Both the cleaning management device and the cleaning management system according to the present invention are described in one embodiment. The cleaning management system is described in this specification. The cleaning management device is described together with the cleaning management system. However, the present invention is not limited to the embodiments described below.

[0011] Objects whose cleaning is managed by a cleaning management system may be referred to as cleaning targets. In this specification and drawings, cleaning targets may be indicated using the symbol M or the term cleaning target M. That is, cleaning target M is an object to be cleaned with a cleaning material. Also, in Figures 1A and 1B, for example, as described above, the symbol M indicates a cleaning target. Examples of cleaning targets M include mobile objects and non-mobile objects. Regarding examples of mobile objects, there are no particular limitations. Specifically, examples of mobile objects include aircraft, helicopters, transport vehicles, pickup trucks, armored vehicles, buses, wheeled armored vehicles, motorcycles, bicycles, aerial drones, underwater drones, surface drones, ships, etc. The above-mentioned aircraft include military aircraft such as fighter jets, passenger planes, transport planes, etc. The above-mentioned ships include military vessels such as aircraft carriers and destroyers.

Figures 1A and 1B show examples where the object to be cleaned M is an aircraft.

[0012] A cleaning management system can be particularly effective when the object to be cleaned, M, is a moving object. Moving objects often require efficient operation. For example, if the moving object is an aircraft, efficient operation is crucial. Examples of efficient operation may include operation that is fuel-efficient and operation that ensures reliable flight when needed.

[0013] The following description is a preferred example of the present invention, and the content of the present invention is not limited to the embodiments described.

[0014] The configurations shown in Figures 1A, 2, 3, etc., are examples of a single embodiment and are not limited to those shown in each figure. Furthermore, the dimensions such as size shown in Figure 1, etc., are for convenience only and are not limited to the size relationships shown in Figure 1.

[0015] [1. Cleaning Management System] [1-1. Configuration of the Cleaning Management System] The cleaning management system 100 includes a cleaning management device 10, a measuring device 20, and a cleaning device 30, as shown in Figures 1A, 1B, 2, 3, etc. Figure 1 is a configuration diagram illustrating one embodiment of the cleaning management system according to the present invention.

[0016] The cleaning management system 100 may have a configuration that enables information communication between the cleaning management device 10 and the measuring device 20. An example of a case where information communication is possible between the cleaning management device 10 and the measuring device 20 is the example shown in Figure 1A. That is, an example of the cleaning management system 100 is an example in which the cleaning management device 10 and the measuring device 20 are connected wirelessly, as shown in Figure 1A. In the cleaning management system 100, the cleaning management device 10 and the measuring device 20 may be connected by wire. Note that in Figure 1A, the dashed line connecting the measuring device 20 and the object to be cleaned M is a line drawn for convenience. The dashed line connecting the measuring device 20 and the object to be cleaned M is a dashed line that shows on the drawing the state in which the sensor 21A of the measuring device 20, which will be described later, is measuring the state of the object to be cleaned M.

[0017] Furthermore, the cleaning management device 10 and the measuring device 20 may be connected via a communication line. Examples of communication lines include Bluetooth®, the Internet, and wireless LAN lines. In connection via a communication line, at least one of the cleaning management device 10 and the measuring device 20 may be connected to the communication line either wired or wirelessly. Also, a combination of wired and wireless connections may be used for the connection between the cleaning management device 10 and the measuring device 20. The same applies to the following case. The following case refers to the case in which the cleaning device 30 is connected to at least one of the cleaning management device 10 and the measuring device 20 via a communication line. This case will be explained later. Note that in Figure 1A, the dashed line connecting the cleaning device 30 and the object to be cleaned M is drawn for convenience. The aforementioned dashed line connecting the cleaning device 30 and the object to be cleaned M is a dashed line that shows on the drawing the state in which the object to be cleaned M is being cleaned after the cleaning material has been released from the cleaning device 30. In Figure 1A, both a dashed line connecting the cleaning device 30 and the object to be cleaned M, and a dashed line connecting the measuring device 20 and the object to be cleaned M are shown. However, this does not mean that the cleaning management system 100 is limited to cases where the cleaning device 30 and the measuring device 20 are operated simultaneously. In the cleaning management system 100, the cleaning device 30 and the measuring device 20 may be operated individually and independently.

[0018] Furthermore, in the cleaning management system 100, the cleaning device 30 may be configured to communicate information with at least one of the cleaning management device 10 and the measuring device 20. In the example shown in Figure 1A, the cleaning device 30 is configured to communicate information wirelessly with the cleaning management device 10. Examples of cases in which the cleaning device 30 can communicate information with at least one of the cleaning management device 10 and the measuring device 20 include the following. That is, the example of the cleaning management system 100 includes cases in which the cleaning management device 10 and the measuring device 20 are connected wirelessly or by wire, as shown for the measuring device 20. In addition, the cleaning device 30 may be connected to a communication line via a base station to at least one of the cleaning management device 10 and the measuring device 20.

[0019] Furthermore, the cleaning management system 100 is not limited to cases where the cleaning management device 10 and the measuring device 20 are connected via a communication line. In the cleaning management system 100, the cleaning management device 10 and the measuring device 20 do not need to be connected via a communication line or the like. Also, the cleaning device 30 does not need to be connected to both the cleaning management device 10 and the measuring device 20 via a communication line or the like.

[0020] The cleaning management system 100 is not limited to having only a combination of a cleaning management device 10, a measuring device 20, and a cleaning device 30. For example, the cleaning management system 100 may have a server device for storing information (not shown). In the cleaning management device 10, the server device may be configured to communicate with at least one of the cleaning management device 10, the measuring device 20, and the cleaning device 30. In particular, from the viewpoint of being able to store a large amount of information related to cleaning management, the server device may be configured to communicate with the cleaning management device 10.

[0021] [1-2. Functions of the Cleaning Management System] The cleaning management system 100 has a function to measure the surface of the object to be cleaned M and a function to clean the object to be cleaned M. The cleaning management system 100 has a cleaning execution information acquisition unit that acquires information on the cleaning execution content (cleaning execution content information) corresponding to the cleaning performed on the object to be cleaned M. The cleaning management system 100 has a cleaning management information determination unit that determines cleaning management information. The cleaning management system 100 has a function to store cleaning management information.

[0022] The function of measuring the surface of the object to be cleaned M can be realized by the measuring device 20. The measuring device 20 has a configuration that acquires information corresponding to the type of specified element. Examples of information corresponding to the type of specified element include light wavelength and spectral waveform. The measuring device 20 may also have a configuration that acquires information corresponding to the abundance of the specified element. Examples of information corresponding to the abundance of an element include values ​​such as light intensity, absorbance, electrical resistance and magnetic force.

[0023] The function of cleaning the object to be cleaned M can be achieved by the cleaning device 30.

[0024] The functions of acquiring information on the cleaning process, specifically how the object M was cleaned with the cleaning material, and determining cleaning management information, can be implemented by the cleaning management device 10. Furthermore, the function of storing the cleaning management information can also be implemented by the cleaning management device 10. The cleaning management device 10 may also have a function for acquiring information on the types of elements.

[0025] In other words, as shown in Figure 2, the cleaning management system 100 includes at least an element type information acquisition unit 10A, a cleaning execution content information acquisition unit 10B, a cleaning management information determination unit 10C, and a cleaning management storage unit 10D in the cleaning management device 10. Figure 2 is a functional block diagram of one embodiment of the cleaning management device 10.

[0026] The element type information acquisition unit 10A acquires element type information as information about the types of elements. The element type information is information about the types of elements contained in the chemical substance adhering to the surface of the object to be cleaned M. Furthermore, the element type information is information about at least one specified type of element. The cleaning management system 100 has a configuration that acquires information associated with the specified types of elements. Examples of information associated with the abundance of elements include values ​​such as light intensity, absorbance, electrical resistance, and magnetic force, as shown in the above description of the measuring device 20.

[0027] The timing for acquiring elemental type information can be before, after, or during cleaning of the object to be cleaned. Acquiring elemental type information before cleaning makes it possible to determine whether or not chemical substances are present on the surface of the object before cleaning. If elemental type information is acquired both before and after cleaning, the effectiveness of the cleaning can be confirmed. Specifically, the effectiveness of the cleaning can be confirmed by comparing the elemental composition of the chemical substance before cleaning with the elemental composition of the chemical substance after cleaning. If elemental type information is acquired both before and during cleaning, the cleaning can be carried out while confirming the effectiveness of the cleaning. Specifically, the effectiveness of the cleaning can be confirmed by comparing the elemental composition of the chemical substance before cleaning with the elemental composition of the chemical substance during cleaning.

[0028] The cleaning execution information acquisition unit 10B acquires cleaning execution information. The cleaning execution information refers to information about the cleaning process performed on the cleaning target M. The cleaning execution information is information about the cleaning conditions applied when the cleaning target M was cleaned. Furthermore, the cleaning execution information is information obtained by performing the cleaning on the cleaning target M. In other words, the cleaning execution information is information obtained by performing the cleaning using the cleaning device 30 described above.

[0029] The cleaning management information determination unit 10C determines the cleaning management information. The cleaning management information indicates information that associates the cleaning procedure with the type of element identified. The cleaning procedure indicates the details of the cleaning performed on the object to be cleaned.

[0030] The cleaning management memory unit 10D stores cleaning management information.

[0031] The element type information acquisition unit 10A, the cleaning execution content information acquisition unit 10B, the cleaning management information determination unit 10C, and the cleaning management storage unit 10D are realized by the control unit 16 and storage unit 12, etc., which will be described later and are mounted on the cleaning management device 10. Because the cleaning management device 10 has the cleaning execution content information acquisition unit 10B, the cleaning management information determination unit 10C, and the cleaning management storage unit 10D, the cleaning management device 10 has the function of acquiring information on elements present on the surface of the object to be cleaned M with the cleaning material, and the function of storing the cleaning execution content.

[0032] Furthermore, the cleaning management system 100 may have an element abundance-corresponding information acquisition unit. The element abundance-corresponding information acquisition unit has the function of acquiring element abundance information. That is, all element abundance-corresponding information acquisition units shown herein may be referred to as element abundance information acquisition units. Element abundance information can be obtained by measuring the cleaning target M that is being cleaned with the cleaning material. That is, element abundance information is obtained by measuring the cleaning target M that is being cleaned with the cleaning material. The acquired element abundance information is information on the abundance of at least one of the specified elements contained in the chemical substance adhering to the surface of the cleaning target M.

[0033] The timing for acquiring elemental abundance information is the same as for acquiring elemental type information; it can be done before, after, or during the cleaning of the object being cleaned.

[0034] The cleaning management system 100 may have an element abundance estimation unit. The element abundance estimation unit has the function of estimating the abundance of elements that could not be measured by the measuring device 20, based on the elemental component ratios and information on chemical substances that are known in advance. Specifically, a sodium abundance estimation unit can be exemplified as an element abundance estimation unit. The sodium abundance estimation unit has the function of determining the amount of sodium contained in the chemical substance according to the amount of potassium present. Specifically, the cleaning management system 100 has an element abundance corresponding information acquisition unit, and the element abundance corresponding information acquisition unit can determine the amount of potassium present. Furthermore, by having a sodium abundance estimation unit, the cleaning management system 100 can determine the amount of sodium contained in the chemical substance according to the determined amount of potassium present. In the cleaning management system 100, the element abundance corresponding information acquisition unit and the sodium abundance estimation unit are realized by a control unit 16, etc., mounted on the cleaning management device 10, which will be described later.

[0035] The cleaning management system 100 may include a cleaning necessity determination unit. The cleaning necessity determination unit determines whether or not the object to be cleaned M needs to be cleaned.

[0036] The cleaning management system 100 may have a cleaning content determination unit. The cleaning content determination unit has a function to determine the cleaning content of the cleaning target M. The cleaning content determination unit may also have a function to determine the cleaning content of the cleaning target M according to the information in the cleaning management information.

[0037] Furthermore, the cleaning management system 100 may have a usage history storage unit. The usage history storage unit has the function of storing information on the history of the cleaning target M being used. In the cleaning management system 100, the usage history storage unit is realized by a storage unit 12, etc., which will be described later and is mounted on the cleaning management device 10.

[0038] Further, the cleaning management system 100 may have a component replacement necessity determination unit. The component replacement necessity determination unit has a function of determining whether component replacement of the cleaning target M is necessary. The cleaning management system 100 may have an availability determination unit. The availability determination unit has a function of determining whether the cleaning target M can be used. In the cleaning management system 100, the component replacement necessity determination unit and the availability determination unit are realized by a control unit 16 or the like described later mounted on the cleaning management device 10.

[0039] Next, the configurations and functions of the respective devices constituting the cleaning management system 100 will be described. The description of each device will be given in the order of the description of the measurement device 20, the description of the cleaning management device 10, and the description of the cleaning device 30.

[0040] [2. Measurement Device] (2-1. Configuration of Specific Device) The measurement device 20 may have a configuration for analyzing the chemical properties and / or physical properties of chemical substances adhering to the surface of the cleaning target M to be cleaned with a cleaning material.

[0041] The configuration for analyzing the chemical properties and / or physical properties of chemical substances may be determined according to the analysis method of chemical substances. Examples of the analysis method of chemical substances include various methods such as fluorescent X-ray analysis, infrared absorption spectroscopy, and surface image analysis.

[0042] The analysis method of chemical substances to be realized by the measurement device 20 may be realized by information measured non-contact with respect to the cleaning target M. Examples of information measured non-contact with respect to the cleaning target M include measurement data described later. For example, when the analysis method of chemical substances is fluorescent X-ray analysis, examples of the measurement device 20 include a device having a fluorescent X-ray detection sensor as a sensor 21A described later and an X-ray irradiator as an energy irradiator. In this case, according to the measurement device 20, the fluorescent X-ray generated in response to the irradiation of the cleaning target M with X-rays from the X-ray irradiator is detected by the sensor 21A. Therefore, the fluorescent X-ray analysis is realized non-contact with respect to the cleaning target M using the measurement device 20. By configuring the measurement device 20 to be able to perform the analysis method of chemical substances non-contact with respect to the cleaning target M, the risk of physically damaging the surface state of the cleaning target M can be reduced.

[0043] In the example of FIG. 1A, the measuring device 20 includes a measuring unit 21. Further, the measuring device 20 may have a measurement information processing unit 22. Note that the dimensions of the measuring device 20 may be such that an operator can hold it. From the perspective of dimensions, examples of the measuring device 20 include handy-type devices. Since the dimensions of the measuring device 20 are such that an operator can hold it, for example, the operator can easily perform the measurement of the cleaning target M while holding the measuring device 20.

[0044] The measuring unit 21 is configured to be able to obtain predetermined data with the sensor 21A. The predetermined data obtained with the sensor 21A is measurement data.

[0045] The sensor 21A detects a predetermined response regarding the chemical substance adhering to the surface of the cleaning target M. The predetermined response is a response corresponding to the chemical properties and / or the physical properties of the chemical substance. Examples of the response include various responses such as optical responses such as light absorption, fluorescence, and phosphorescence, and electromagnetic responses such as electromagnetic waves. Further, in the measuring unit 21, data corresponding to the response detected by the sensor 21A is obtained. The data corresponding to the response detected by the sensor 21A may be referred to as measurement data as described above. Examples of data that may be regarded as measurement data include various types of data such as optical data, chemical data, and electromagnetic data.

[0046] The sensor 21A may be determined according to the content of the above-described chemical substance analysis method. Specifically, the sensor 21A is not limited. Examples of the sensor 21A include various sensors such as a surface sensor, a fluorescence detection sensor, an electric sensor, a magnetic sensor, and an image sensor. Examples of the fluorescence detection sensor include a fluorescence detector. Examples of the fluorescence detector include a fluorescent X-ray detection sensor. For example, when the measuring unit 21 has a configuration for performing fluorescent X-ray analysis, a fluorescent X-ray detection sensor can be specifically used as the sensor 21A. Note that in this case, the measuring device 20 has a function of performing fluorescent X-ray analysis.

[0047] If the chemical substance analysis method described above is a method of detecting a response corresponding to a predetermined energy irradiation, the measurement unit 21 may have an energy irradiator (not shown) for realizing detection by the sensor 21A. However, in the cleaning management system 100, the device having the energy irradiator may be provided as a separate device from the measurement device 20. For example, if the chemical substance analysis method is fluorescent X-ray analysis, an X-ray irradiator can be specifically cited as the energy irradiator. The arrangement of the energy irradiator should be such that detection by the sensor 21A can be realized. The arrangement of the energy irradiator may be determined according to its type.

[0048] The measurement information processing unit 22 is configured to process the measurement data obtained by the measurement unit 21. An example of how the measurement information processing unit 22 processes the measurement data is to identify the types of elements contained in the chemical substance according to the measurement data obtained by the measurement unit 21. The chemical substance referred to here is a chemical substance attached to the surface of the object to be cleaned M. Processing the measurement data includes at least one selected from transmitting the measurement data, processing the measurement data, and editing the measurement data.

[0049] Furthermore, the measurement information processing unit 22 may be configured to identify the amount of elements contained in the chemical substance according to the measurement data obtained by the measurement unit 21. There may be multiple types of elements contained in the chemical substance. The amount of an element may be specified for one type of element contained in the chemical substance. The amount of an element may be specified for each type of element. Note that the concept referred to by the term "types of elements contained in the chemical substance" includes the types of elements contained in the chemical substance attached to the surface of the object to be cleaned M.

[0050] The measurement information processing unit 22 may have computer functions. The measurement information processing unit 22 has a measurement information control unit. The measurement information control unit has a CPU (Central Processing Unit), RAM (Random Access Memory), and ROM (Read Only Memory), etc. The CPU is configured to be able to execute programs and instructions for processing measurement data. In the measurement information control unit, the CPU reads and executes the code of various programs stored in the ROM and RAM.

[0051] The measuring device 20 may include a measurement information communication unit. The measurement information communication unit is configured to transmit information corresponding to the type of element to the outside. Preferably, the measuring device 20 also includes a measurement information display unit. The measurement information display unit is configured to display information corresponding to the type of element. Examples of displaying information corresponding to the type of element in the measurement information display unit include display using at least one medium selected from various media, including images, video, and sound. The measuring device 20 may also include a measurement information input unit. The measurement information input unit is configured to allow information to be input. The measurement information input unit may have, for example, a keyboard or a touch panel.

[0052] The measuring device 20 may be equipped with a camera. The camera may be omitted, and therefore its illustration is omitted in each drawing. The position of the camera is not particularly limited. However, in the measuring device 20, it is preferable that the camera is positioned so that the portion of the object to be cleaned M that is to be measured by the measuring unit 21 can be photographed. By having a camera in the measuring device 20, the measurement area m can be identified more accurately when measuring the object to be cleaned M. The measurement area m indicates the region that is to be measured, such as the measurement location or part. For example, the measuring device 20 is equipped with a camera, and the measurement information processing unit 22 of the measuring device 20 has image information of the measurement area m stored in advance. The measurement information processing unit 22 of the measuring device 20 then compares the image from the camera with the stored image information of the measurement area m. As a result, according to this example of the measuring device 20, the measurement area m can be identified accurately.

[0053] (2-1. Function of the measuring device) The measuring device 20 has the function of measuring the surface of the object to be cleaned M. The measuring device 20 determines measurement data by measuring the surface of the object to be cleaned M. The measurement data is data corresponding to the chemical substance adhering to the surface of the object to be cleaned M. The measurement data also includes information on the type of at least one specific element contained in the chemical substance. Examples of information on the type of element include light wavelength, spectral waveform, etc.

[0054] Furthermore, the measuring device 20 may have a function to determine the abundance of a specified element. In this case, the measurement data may include information on the abundance of the specified element. The specified element is at least one element contained in the chemical substance. When the measurement of the object to be cleaned is performed by measuring the object to be cleaned M, which is cleaned with a cleaning material, by fluorescent X-ray analysis, the type of element and its abundance may be determined as follows. That is, the type of element and its abundance may be determined according to the position and intensity of the peak wavelength in the spectral waveform of the fluorescent X-ray. In this case, examples of information on the abundance of the element may include information on the spectral waveform and information on the intensity at the peak wavelength. Note that the spectral waveform is determined according to the type of element, etc., so the peak wavelength is not limited to one, but may be two or more. Accordingly, the intensity information may also be two or more, as information for each peak wavelength.

[0055] Furthermore, the spectral waveform information and the intensity information at the peak wavelength may be a set of information. The spectral waveform information and the intensity information at the peak wavelength may also be identified individually and independently.

[0056] The function for measuring the surface of the object to be cleaned M should be determined according to the chemical analysis method described above performed by the measuring device 20. Examples of the function for measuring the surface of the object to be cleaned M may include various functions such as a function for measuring the visual condition of the surface, a function for performing X-ray fluorescence analysis, and a function for performing infrared absorption spectroscopy.

[0057] The chemical substances adhering to the surface of the object to be cleaned M, and the elements identified by the measuring device 20, are not particularly limited. The chemical substances adhering to the surface of the object to be cleaned M, and the elements identified by the measuring device 20, should be determined according to the chemical substance analysis method to be performed by the measuring device 20.

[0058] The chemical substances adhering to the surface of the object to be cleaned M are the chemical substances to be measured by the measuring device 20. The chemical substances adhering to the surface of the object to be cleaned M represent substances whose abundance on the surface of the object to be cleaned has increased compared to the standard state, or chemical substances that were not observed in the standard state. Chemical substances that were not observed in the standard state are chemical substances that have newly adhered to the surface of the object to be cleaned M.

[0059] The reference state refers to a predetermined state defined as the surface state of the object to be cleaned M. The reference state may be defined according to the object to be cleaned M. Specifically, examples of the reference state include various states such as the surface state of the object to be cleaned M immediately after its manufacture and the surface state of the object to be cleaned M when it is deployed to its place of use. The reference state is also defined as the state of the measurement area m. If there are multiple measurement areas m, as described later, the reference state may be defined for each measurement area m of the object to be cleaned M. There may be one or more measurement areas m. If there are multiple measurement areas m, they may be indicated as multiple measurement areas m1, m2, etc. For example, the notation multiple measurement areas m1, m2 refers to measurement area m1 and measurement area m2. If multiple measurement areas such as measurement area m1 and measurement area m2 are not distinguished, they may be referred to as measurement area m.

[0060] The measurement area m refers to a predetermined area defined from the surface of the object to be cleaned M. The measurement area m may be specified at one location or at multiple locations. An example of a measurement area m is that it may include an area of ​​the object to be cleaned M where the accumulation of dirt significantly affects the function of the object to be cleaned M. If the measurement area m is such an area, it is possible to select the part of the object to be cleaned M that affects its function and clean that selected part. Furthermore, if multiple measurement areas m1, m2, etc. are defined, it becomes easy to determine the cleaning content for each measurement area.

[0061] The type of chemical substance adhering to the surface of the object to be cleaned M is not particularly limited, provided that it is the chemical substance to be measured by the measuring device 20. This chemical substance may be a metal compound. Metal compounds may potentially be the cause of rust and scale on the object to be cleaned M. From the perspective of the possibility that metal compounds may be the cause, it is important that they be effectively removed from the object to be cleaned M. If the chemical substance to be measured by the measuring device 20 is a metal compound, the cleaning management system 100 makes it possible to efficiently and systematically remove the metal compound adhering to the surface of the object to be cleaned M. However, this does not prohibit the chemical substance adhering to the surface of the object to be cleaned M, which is the chemical substance to be measured, from being a metal compound. Specifically, examples of chemical substances adhering to the surface of the object to be cleaned M may include non-metallic inorganic compounds, metal salts and other inorganic substances such as metals, organic substances such as proteins, and substances in which various elements constituting inorganic substances and organic substances are chemically bonded. The concept of organic substances such as proteins may include salts of those organic substances. Examples of substances in which various elements constituting inorganic matter and organic matter are chemically bonded together may include components of blood found in living organisms.

[0062] Regarding the function of determining the abundance of the specified element described above, the specified element may be selected from a first group of elements. The first group of elements is a group that includes at least one element selected from alkali metals having an atomic weight greater than or equal to sodium, and alkaline earth metals having an atomic weight greater than or equal to magnesium. Examples of alkali metals include sodium and potassium. Examples of alkaline earth metals include magnesium and calcium. It is preferable that the elements included in the first group of elements are elements that can form halides and / or oxides. Therefore, for example, the first group of elements may consist of potassium, magnesium, and calcium. When the specified element is selected from the first group of elements, the chemical substance adhering to the surface of the cleaning target M, which is the chemical substance to be measured by the measuring device 20, will be a metal compound. Sodium chloride can easily cause rust to form on the cleaning target M. For this reason, it is important that sodium is removed efficiently. From this viewpoint, it is preferable that the specified element is sodium or contains sodium. In this case, the chemical substance that includes sodium and other elements belonging to the first group of elements is sodium chloride and other elements. Magnesium carbonate and calcium carbonate can form scale on the material M being cleaned. Therefore, it is important that magnesium carbonate and calcium carbonate are efficiently removed. From this perspective, it is preferable that the specified element is at least one of magnesium carbonate and calcium carbonate, or contains at least one of magnesium carbonate and calcium carbonate. Chemical substances belonging to the first element group that include magnesium, calcium, etc. are magnesium carbonate and calcium carbonate. Thus, it is important that elements belonging to the first element group can be effectively cleaned.

[0063] Furthermore, the specified elements described above may be selected from a second group of elements. The second group of elements includes at least halogens having an atomic weight greater than or equal to that of chlorine. The elements constituting the second group of elements may be capable of forming negative ions and metal salts. Compounds containing halogens such as chlorine may easily cause rust to form on the object being cleaned when they form sodium salts. For this reason, it is important that compounds containing halogens such as chlorine be efficiently removed. In other words, it is important that elements belonging to the second group of elements can be effectively cleaned. From this perspective, the elements belonging to the second group of elements may include halogens, and the specified elements described above may be selected from the second group of elements.

[0064] If the identified element described above is at least one element selected from the first and second element groups, the measuring device 20 can specifically be a device that has the function of performing X-ray fluorescence analysis. In this case, the information on the type of element corresponding to the measurement data described above is information determined according to the measurement results obtained by X-ray fluorescence analysis of the cleaning target M that is cleaned with the cleaning material.

[0065] In addition to the classifications of the first and second element groups described above, the identified elements may also be selected from various groups of elements classified by their position on the periodic table or by their properties. These various groups of elements classified by their properties may be referred to as classifications of identified elements. Examples of these various groups of elements may include heavy metals, metals that have been identified as harmful to the human body, rare earth elements, and isotopic elements. Examples of elements belonging to the heavy metal group include chromium (Cr), iron (Fe), silver (Ag), gold (Au), cadmium (Cd), and mercury (Hg). Examples of metals that have been identified as harmful to the human body include cadmium (Cd) and mercury (Hg). Examples of the group of rare earth elements include lanthanide elements such as lanthanum (La) and neodymium (Nd), and actinide elements such as thorium (Th), uranium (U), and plutonium (Pu). Lanthanide and actinide elements may be defined individually as specific elemental classifications. Furthermore, the elements identified by measurement using the measuring device 20 are not particularly limited as long as they are elements. For example, the elements targeted for identification by measurement using the measuring device 20 may be all possible elements. Also, the classification of identified elements may be selected based on the detection limit according to the elements measured by the measuring device 20. For example, in measurement using the measuring device 20, if an element belonging to a predetermined group of elements is present in an amount greater than or equal to a predetermined amount, that predetermined amount is XM. This indicates that the detection limit of the measuring device 20 is XM. In such a case, the classification of identified elements may be a group of elements adhering to the surface of the object to be cleaned M in an amount of XM or more. Examples of units for predetermined amounts include mass and volume.

[0066] [3. Cleaning Management Device] The cleaning management device 10 is a device that determines cleaning management information. The cleaning management information is information that associates the cleaning procedure with element type information. The cleaning procedure is the procedure of cleaning the cleaning target M with the cleaning material. The element type information is information on at least the types of specified elements. As described above, the information on the types of specified elements can be determined, for example, according to the measurement results obtained by measuring the cleaning target M with the measuring device 20. An example of a device that realizes the cleaning management device 10 according to the present invention is an information processing device. In this specification, the description will continue as an example of the case where the cleaning management device 10 is an information processing device.

[0067] (3-1. Overview of the Cleaning Management Device) The cleaning management device 10 is an information processing device with computer functions. The cleaning management device 10 acquires information on the type of element identified and determines the cleaning content, which will be described later. Specifically, examples of the cleaning management device 10 include various devices such as mobile computers, smartphones, notebook personal computers, and desktop personal computers.

[0068] (3-2. Configuration of the Cleaning Management Device) As shown in Figure 3, the cleaning management device 10 comprises a communication unit 11, a storage unit 12, an output unit 13, an input unit 14, an input / output interface unit 15, and a control unit 16. The control unit 16 and the input / output interface unit 15 are electrically connected via a system bus 17. The cleaning management device 10 has a clock function. Figure 3 is a configuration diagram illustrating one embodiment of the cleaning management device 10.

[0069] The communication unit 11 is configured to control the communication status with the measuring device 20, etc. The communication unit 11 may be connected to the measuring device 20 by wire or by wireless connection. The communication unit 11 may also be electrically or electromagnetically connected to a communication line. In other words, in the cleaning management system 100, the electrical or electromagnetic connection between the cleaning management device 10 and the measuring device 20 may be a wired connection, a wireless connection, or a connection via a communication line. Furthermore, the electrical or electromagnetic connection between the cleaning management device 10 and the measuring device 20 may be a combination of wired, wireless, and communication line connections as appropriate.

[0070] The storage unit 12 is composed of, for example, a hard disk drive and / or a solid-state drive. The storage unit 12 stores various types of data. The storage unit 12 also stores various programs and files. Examples of programs that may be stored in the storage unit 12 include operating systems and server programs. For example, if the information processing device that becomes the cleaning management device 10 is connected to a communication line, various programs may be obtained from other server devices via the communication line. Furthermore, various programs may be recorded on a recording medium and read via a drive device.

[0071] As shown in Figure 4, a cleaning implementation management database 12A may be constructed in the storage unit 12. The cleaning implementation management database 12A is a database that stores information relating element types to cleaning implementation details. Examples of element types include element types included in the measurement data of the measuring device. For example, examples of element types include various elements such as magnesium and calcium. In predetermined cases, the cleaning implementation management database 12A may include other elements not included in the measurement data as element types. An example of the predetermined case is when the abundance of other elements not included in the measurement data is estimated from the measurement data of the measuring device. Examples of cleaning implementation details include cleaning date, cleaning location, type of cleaning material, and cleaning time. Examples of cleaning implementation details may include other conditions other than cleaning date, cleaning location, type of cleaning material, and cleaning time. Other conditions other than cleaning date, cleaning location, type of cleaning material, and cleaning time may be referred to as cleaning conditions. Cleaning date, cleaning location, type of cleaning material, cleaning time, and cleaning conditions may be collectively referred to as cleaning conditions. The cleaning execution management database 12A shown in Figure 4 stores information indicating the cleaning date, cleaning location, cleaning materials, and cleaning time. The information indicating the cleaning date clarifies when the cleaning was performed. The information indicating the cleaning location clarifies where the cleaning was performed. The information indicating the cleaning materials clarifies what was used for cleaning. The cleaning time clarifies how long the cleaning took. In addition, the cleaning execution management database 12A may store the cleaning conditions. Pressure and element types are examples of cleaning conditions. That is, the cleaning execution management database 12A may store various types of information, such as information indicating pressure and information indicating element types. Here, the information indicating pressure as an example of cleaning conditions indicates the amount of spray pressure used for cleaning. The information indicating element types as an example of cleaning conditions indicates the type of element targeted when performing the cleaning. The information indicating the type of target element indicates what elements were targeted as constituent elements of the chemical substance measured from the surface of the object being cleaned.Furthermore, the cleaning implementation management database 12A may store information for identifying partitioned areas. In Figure 4, partitioned areas are indicated in the partitioned area column using symbols such as D1, D2, etc. In this specification, including the drawings, partitioned areas may be represented using symbols such as partitioned area D1, partitioned area D2, etc. Also, when no distinction is made between partitioned area D1, etc., they may be referred to as partitioned area D. In Figure 4, the symbols "〇", "〇〇", and "..." indicate some kind of information. Also, for the sake of explanation, when elements such as magnesium, calcium, sodium, and chlorine are described in Figure 4, they are shown in Figure 4 using element symbols. Note that in Figure 4, information may not be present in some of the locations where the symbols "〇", "〇〇", and "..." are indicated.

[0072] The database constructed in the memory unit 12 is not limited to those described above, and various databases corresponding to the functions of the control unit 16 may be constructed.

[0073] For example, a database 12B for determining whether cleaning is necessary may be constructed in the storage unit 12. The database 12B for determining whether cleaning is necessary stores information that associates the types of elements with the judgment criteria values ​​for each element. For example, as shown in Figure 5, elements such as potassium, magnesium, calcium, and chlorine are associated with MS1, MS2, MS3, MS4, etc., respectively. MS1 to MS4 represent numerical values. The units of the judgment criteria values ​​are not limited. Examples of units for judgment criteria values ​​include various units such as mass, amount of substance, and volume.

[0074] For example, a database for estimating values ​​may be constructed in the memory unit 12. An example of a database for estimating values ​​includes a database for estimating sodium values. The database for estimating sodium values ​​is a database that associates the abundance of a predetermined element with the abundance of sodium. An example of a case in which a database for estimating sodium values ​​may be constructed is, for example, the case in which the abundance of sodium is estimated from the abundance of a predetermined element by associating the abundance of a predetermined element with the abundance of sodium.

[0075] Furthermore, the database constructed in the storage unit 12 may be a database corresponding to the function of the control unit 16. Examples of databases corresponding to the function of the control unit 16 include a threshold database for determining whether parts need to be replaced and a threshold database for determining whether parts can be used. The storage unit 12 may have a threshold database for determining whether parts need to be replaced and / or a threshold database for determining whether parts can be used. The threshold database for determining whether parts need to be replaced and the threshold database for determining whether parts can be used each store information that associates element types with thresholds.

[0076] A usage history database may be constructed in the storage unit 12. In this case, the storage unit 12 functions as a usage history storage unit. The usage history database is a database that stores information indicating the usage history of the object to be cleaned M. The usage history of the object to be cleaned M indicates the usage status of the object to be cleaned M. Examples of items stored in the usage history database include various items such as the date and time of use of the object to be cleaned, time, duration, weather, and temperature. Furthermore, if the object to be cleaned M is a moving object such as an aircraft, examples of items stored in the usage history database include various items such as distance traveled, starting point of travel, ending point of travel, altitude of travel, speed of travel, pilot, and date of manufacture.

[0077] A cleaning contents database may be constructed in the storage unit 12.

[0078] The cleaning content database stores information corresponding to information defining the cleaning content, for example. The cleaning content stored in the cleaning content database may be content corresponding to the type of element. For example, an example of a cleaning content database includes a database that stores information defining the cleaning content when the type of element is magnesium. Note that the type of element corresponding to the cleaning content is not limited to metallic elements. For example, an example of a cleaning content database includes a database that stores cleaning content when the type of element is, for example, chlorine. Multiple databases defined for each element may be integrated into a single cleaning content database in the storage unit 12.

[0079] The cleaning content database may be a database associated with each measurement area m or partitioned area D. For example, the storage unit 12 may have a database associated with each type of element corresponding to the measurement data measured in a predetermined measurement area m1 corresponding to partitioned area D1, which can be used as the cleaning content database. By having a database associated with each measurement area m or partitioned area D in this way, it is possible to achieve more effective cleaning according to the condition of the cleaning part of the cleaning target M.

[0080] The information used to identify the cleaning content stored in the cleaning content database includes a group of cleaning content identification items such as type, temperature, pressure, volume, velocity, and time. The individual contents of the cleaning content identification items shown here are as follows: Type refers to the type of cleaning material. Temperature refers to the temperature of the cleaning material. Pressure refers to the pressure at which the cleaning material is sprayed. It refers to the spray volume of the cleaning material. Velocity refers to the spray velocity of the cleaning material. Time refers to the spray duration of the cleaning material. The cleaning content database stores information corresponding to cleaning specification items. Cleaning specification items are items selected from the cleaning content identification item group. The cleaning content database may store information corresponding to cleaning specification items, associated with each type of element. For example, a cleaning content database may be constructed that associates the items of type of element, type of cleaning material, and temperature during cleaning. For example, specific conditions such as Mg, gas-liquid mixture, and 25°C may be associated with each item of type of element, type of cleaning material, and temperature during cleaning, respectively.

[0081] The storage unit 12 and / or ROM 16B may store various programs. Examples of such programs include programs for implementing various functions, such as determining the cleaning content. The CPU 16A of the control unit 16 is configured to execute the various programs stored in the storage unit 12 and / or ROM 16B.

[0082] The output unit 13 has a configuration that enables it to transmit information to a person by acting on the senses such as sight and hearing. An example of a configuration for transmitting information to a person by acting on the sense of sight is a configuration for outputting an image. A specific example of a configuration for outputting an image is shown below. For example, the output unit 13 has a liquid crystal display element or an organic EL element. The organic EL element is an Organic Electro Luminescence element. An example of a configuration for transmitting information to a person by acting on the sense of hearing is a configuration for outputting sound. A specific example of the case where the output unit 13 outputs sound is a case where the output unit 13 has a speaker. The image output by the output unit 13 may be a still image or a moving image, or it may be both a still image and a moving image.

[0083] The input unit 14 is configured to allow information to be input. An example of the configuration of the input unit 14 is a configuration that includes a keyboard and a mouse. The configuration of the input unit 14 may also include at least a part of the configuration of the output unit 13 described above. For example, when the output unit 13 outputs video, the input unit 14 may use at least a part of the configuration that realizes the functions of the output unit 13. To give a specific example, the configuration of the input unit 14 may include a configuration that includes a touch panel, and this configuration that includes a touch panel may also include at least a part of the configuration of the output unit 13.

[0084] The input / output interface unit 15 is configured to perform interface processing between the communication unit 11 and the storage unit 12, etc., and the control unit 16.

[0085] The control unit 16 includes a CPU 16A, ROM 16B, RAM 16C, etc. The CPU 16A reads and executes the code of various programs stored in the ROM 16B and the memory unit 12, thereby determining at least the type of element.

[0086] (3-2. Functions of the Cleaning Management Device) The cleaning management device 10 has a function to acquire information such as the type of element identified. The cleaning management device 10 also has a function to store information that associates the cleaning execution content with the type of element identified. The cleaning execution content is the content of the cleaning performed on the object to be cleaned. These functions of the cleaning management device 10 are realized by the element type information acquisition unit 10A, the cleaning execution content information acquisition unit 10B, the cleaning management information determination unit 10C, and the cleaning management storage unit 10D, as described above with reference to Figure 2, etc. The element type information acquisition unit 10A to the cleaning management storage unit 10D are realized by the control unit 16, etc., which will be described later and is mounted on the cleaning management device 10.

[0087] The cleaning management device 10 may have a function to acquire information on the abundance of a specified element. This function can be realized by the element abundance-corresponding information acquisition unit described above. The element abundance-corresponding information acquisition unit is realized by a control unit 16, etc., which will be described later and mounted on the cleaning management device 10. The cleaning management device 10 may have a function to determine whether or not cleaning is necessary for the cleaning target M. This function can be realized by the cleaning necessity determination unit described above. Furthermore, the cleaning management device 10 may have a function to determine the amount of sodium contained in the chemical substance according to the amount of potassium present as a specified element. This function can be realized by the sodium abundance estimation unit described above. The sodium abundance estimation unit is realized by a control unit 16, etc., which will be described later and mounted on the cleaning management device 10.

[0088] The cleaning management device 10 may have a function to store information about the history of past use of the cleaning target M. This function can be implemented by a usage history storage unit. The usage history storage unit is implemented by a storage unit 12, etc.

[0089] [4. Cleaning device] The cleaning device 30 is a device having a cleaning section (not shown) for cleaning the object to be cleaned M with a cleaning material.

[0090] The configuration of the cleaning unit is not particularly limited. The cleaning unit only needs to be configured to discharge (spray) cleaning material from a nozzle toward the object to be cleaned M. The cleaning unit may also include, for example, a nozzle for discharging the object to be cleaned, a pump for discharging the cleaning material, and piping connecting the pump and the nozzle, although these are not shown in the diagram. The piping is configured to allow the cleaning material to be delivered from the pump toward the nozzle. The cleaning device 30 may also include a tank (not shown). The cleaning device 30 may also have a configuration for storing cleaning material in the tank. In this case, it is preferable that the cleaning device 30 is configured so that cleaning material is sent from the tank to the cleaning unit and that cleaning material is discharged from the nozzle of the cleaning unit. The cleaning device 30 may also be configured so that cleaning material can be supplied to the cleaning device 30 from the outside. In this case, the tank may be omitted.

[0091] Furthermore, the cleaning device 30 may be configured to control the pressure, discharge amount (injection amount), temperature, discharge speed (injection speed), etc., when discharging (injecting) the cleaning material from the nozzle. Also, if the cleaning material is a gas-liquid mixture as described later, the cleaning device 30 may be configured to control the concentration of bubbles.

[0092] The cleaning device 30 may have a cleaning execution information processing unit. The cleaning execution information processing unit may be configured to control the execution of cleaning by the cleaning device 30. The cleaning execution information processing unit may also be configured to determine cleaning execution information. Cleaning execution information refers to information corresponding to the cleaning execution performed by the cleaning device 30. The cleaning execution information processing unit may also be configured to record cleaning execution information, which is information corresponding to the cleaning execution performed by the cleaning device 30, and / or to transmit cleaning execution information to an external party. An example of transmitting cleaning execution information to an external party is to transmit cleaning execution information to the cleaning management device 10. The cleaning execution information processing unit may also be configured to process and / or edit the cleaning execution information from the cleaning device 30.

[0093] The cleaning execution information processing unit has computer functions. The cleaning execution information processing unit has a cleaning execution information control unit. The cleaning execution information control unit has a CPU, RAM, and ROM, etc. In the cleaning execution information control unit, the CPU is configured to be able to execute programs and instructions for processing cleaning execution information. In the cleaning execution information control unit, the CPU reads the code of various programs stored in ROM and RAM and executes the various programs.

[0094] The cleaning device 30 may include a cleaning information communication unit. The cleaning information communication unit is configured to transmit information corresponding to the cleaning execution content (cleaning execution content information) to the cleaning management device 10. The cleaning device 30 may also include a cleaning execution information display unit. The cleaning execution information display unit is configured to display selected information. Examples of displaying selected information in the cleaning execution information display unit include displaying using one or more media selected from a group of media having various media such as images, videos, and sounds. The selected information is information selected from the cleaning execution content information. The selected information may include all the information of the cleaning execution content included in the cleaning execution content information. The cleaning information input unit is configured to allow information input. The cleaning information input unit may have, for example, a keyboard or a touch panel.

[0095] The cleaning material may consist of a fluid that can be used to clean the object to be cleaned M. Examples of cleaning materials include cleaning liquids. Examples of cleaning liquids include water, aqueous solutions, and gas-liquid mixtures. Examples of cleaning liquids may include mixtures of aqueous solutions and organic substances. Examples of organic substances include surfactants. From the viewpoint of achieving efficient cleaning and suppressing the rinsing process time, it is preferable that the cleaning material is a gas-liquid mixture or a liquid containing a gas-liquid mixture. When the cleaning material is a gas-liquid mixture or a liquid containing a gas-liquid mixture, the cleaning device 30 may have a bubble generator. The bubble generator is not particularly limited, but a bubble generator 300, which will be described later, may be used.

[0096] Next, we will explain gas-liquid mixtures.

[0097] A gas-liquid mixture that may be used as a cleaning material (or may be included in a cleaning material) contains bubbles in the liquid. At least some of the bubbles in the gas-liquid mixture have a diameter of less than 1 μm (the average bubble diameter of at least some of the bubbles is less than 1 μm). However, it is preferable that all of the bubbles in the gas-liquid mixture are less than 1 μm (the average bubble diameter of the bubbles is less than 1 μm). Bubbles with a diameter of 100 μm or less are sometimes called fine bubbles. Bubbles with a diameter of 1 μm or more and 100 μm or less are sometimes called microbubbles. Bubbles with a diameter of less than 1 μm are sometimes called ultrafine bubbles or nanobubbles. The term "fine bubble" shall be used as a term that encompasses microbubbles and ultrafine bubbles. It is preferable that at least some of the bubbles in the gas-liquid mixture are ultrafine bubbles. The gas-liquid mixture is a state in which ultrafine bubbles are dispersed in the liquid. This does not preclude the inclusion of bubbles other than ultrafine bubbles in the gas-liquid mixture used as a cleaning material (or contained in the cleaning material); the gas-liquid mixture may contain microbubbles, etc.

[0098] The gaseous components within the bubbles of a gas-liquid mixture are not particularly limited. The gaseous components within the bubbles may be gases taken in from the outside, or gaseous components dissolved in the liquid used in the production of the gas-liquid mixture. Examples of gaseous components dissolved in a liquid include, for example, dissolved carbon dioxide dissolved in water, or dissolved oxygen and nitrogen dissolved in water, if the liquid is water.

[0099] The bubble diameter refers to the diameter of the bubble. The average bubble diameter refers to the average value of the bubble diameter. The average bubble diameter can be determined from the bubble diameter distribution. The average bubble diameter of some bubbles can be determined from the bubble diameter distribution. The bubble diameter can be determined when measuring the bubble diameter distribution. The bubble diameter and average bubble diameter can be determined using techniques for measuring the bubble diameter distribution (particle size distribution) of bubbles contained in a gas-liquid mixture. Examples of techniques for measuring the bubble diameter distribution (particle size distribution) include methods using laser diffraction / scattering type particle size distribution analyzers. As a method for determining the bubble diameter distribution, particle size analysis - particle trajectory analysis method (particle tracking analysis method) in accordance with JIS Z 8829:2021 can also be mentioned.

[0100] Bubble concentration (units / cm³) of gas-liquid mixture ３ ) is not particularly limited. However, from the viewpoint of effectively exhibiting the function of the gas-liquid mixture containing bubbles having a predetermined bubble diameter, the bubble concentration for bubbles smaller than 1 μm in the gas-liquid mixture should be 20 million bubbles / cm³. ３ Preferably, the number is 50 million / cm² or higher. ３ It is more preferable that the number be 60 million / cm². ３ It is even more preferable that the liquid contains 20 million bubbles with a diameter of less than 1 μm per cm. ３ If the above conditions are met, the gas-liquid mixture can exhibit a fouling prevention effect. The liquid contains 50 million bubbles with a diameter of less than 1 μm per cm². ３ The above conditions allow for effective cleaning of biofilms (aggregates formed by microorganisms on solid surfaces). The liquid contains 60 million bubbles with a diameter of less than 1 μm per cm². ３ By doing so, these effects can be further enhanced.

[0101] There is no particular upper limit to the bubble concentration of a gas-liquid mixture, but from the viewpoint of ease of stable bubble generation, the upper limit to the bubble concentration of a gas-liquid mixture is approximately 5 billion bubbles / cm³. ３It is preferable that the concentration be within a certain range. The bubble concentration can be determined using methods such as those exemplified above for determining the bubble diameter and average bubble diameter of the bubbles mentioned above.

[0102] It is preferable that the bubbles contained in the gas-liquid mixture have a negative potential. The negative potential charge state of the bubbles can be achieved by the bubble generator 300, described later, being a cavitation-type bubble generator. The negative potential charge state of the bubbles can be achieved depending on the cavitation in the liquid fluid within the liquid channel of the bubble generator 300 and the magnitude of the static electricity due to the friction of the fluid within the channel. The magnitude of the negative potential can be determined according to various conditions such as the diameter of the bubbles. The friction of the fluid within the channel refers to the friction between the members forming the channel and the bubbles.

[0103] The gas-liquid mixture can be prepared specifically as follows.

[0104] A gas-liquid mixture can be produced using a bubble generator.

[0105] The configuration of the bubble generator is not particularly limited. The bubble generator only needs to be configured to generate fine bubbles, such as ultrafine bubbles, in a liquid and form a gas-liquid mixture in which the bubbles are dispersed in the liquid. Examples of such bubble generators include devices that apply various bubble generation mechanisms as needed, such as cavitation type, micropore type, ultrasonic type, swirling flow type, static mixer type, Venturi type, steam condensation type, pressurized dissolution type, and gas-liquid mixing shear type.

[0106] However, from the viewpoint of efficiently generating fine bubbles such as ultrafine bubbles having a negative potential as bubbles contained in the gas-liquid mixture, it is preferable to prepare the gas-liquid mixture using a cavitation type device as the bubble generator 300. As a cavitation type device, a device like the one shown in the following "Example of a Bubble Generator" can be used. Next, as an example of a bubble generator, an example of a cavitation type bubble generator will be described with reference to Figure 6.

[0107] (An example of a bubble generator) As shown in Figure 6, the bubble generator 300 includes a receiving section 110 for receiving liquid components that will be used as raw materials (referred to as raw material liquid), a bubble generation mechanism 120 for generating a gas-liquid mixture in which bubbles are dispersed in the raw material liquid supplied from the receiving section 110, and a discharge section 130 for discharging the gas-liquid mixture. Figure 6 is a diagram illustrating one embodiment of the bubble generator. The gas-liquid mixture flowing out of the discharge section 130 then flows further towards the pump through the supply pipe.

[0108] (Bubble generation mechanism) The bubble generation mechanism 120 has a flow channel forming body 121 and a plurality of impacting bodies 124. The flow channel forming body 121 has a liquid flow channel 122 on its inner circumferential surface 121A side and a throttling structure 123. The throttling structure 123 has a first portion 123A in which the cross-sectional diameter of the inner circumferential surface 121A (the cross-sectional diameter determined by the cross-section of a plane whose normal direction is assumed to be the longitudinal direction of the liquid flow channel 122) decreases from the upstream end 125 (inlet) to the downstream end 126 (outlet). The throttling structure 123 has a second portion 123B in which the cross-sectional diameter of the inner circumferential surface 121A increases from the upstream end 125 to the downstream end 126. The first portion 123A is located upstream of the second portion 123B. The multiple impactors 124 protrude inward from the inner circumferential surface 121A of the flow channel forming body 121 and are adjacent to each other across a predetermined segment region. The multiple impactors 124 are positioned between (or at the boundary between) the first portion 123A and the second portion 123B in the longitudinal direction of the liquid flow channel 122. However, this does not prohibit the multiple impactors 124 from being formed in either the first portion 123A or the second portion 123B. The segment region refers to the area of ​​the cross-section of the inner circumferential surface 121A that is divided by adjacent impactors 124 in the circumferential direction of the inner circumferential surface 121A. The multiple impactors 124 are arranged to form a gap between their tips that narrows the flow channel. The bubble generation mechanism 120 is configured so that the flow channel forming body 121 can pass the raw material liquid from the upstream end 125 to the downstream end 126. As mentioned above, it is preferable that a pump (not shown) for supplying raw material liquid is installed upstream and / or downstream of the bubble generator 300. This pump supplies the raw material liquid to the bubble generator 300 so that the water pressure, flow velocity, and volume of the raw material liquid are each above predetermined values. In the bubble generator 300, the concentration of fine bubbles generated differs depending on the pressure, flow velocity, and flow rate of the liquid flowing through the liquid channel 122. Examples of fine bubbles include microbubbles and ultrafine bubbles. In the bubble generator 300, a high concentration of fine bubbles can be generated in the liquid by increasing at least one of the liquid pressure, flow velocity, and flow rate.

[0109] The bubbles dispersed in the gas-liquid mixture obtained by the bubble generator 300 are formed by cavitation in the raw material liquid, as described above, and are gaseous components associated with the cavitation of components dissolved in the raw material liquid. In such bubbles, vaporized oxygen (dissolved oxygen) and vaporized nitrogen (dissolved nitrogen) that were dissolved in the water constituting the raw material liquid are included in the bubbles. The gaseous components in the bubbles may be determined according to the desired effect of the gas-liquid mixture. For example, if the gas-liquid mixture is to be effective in removing biofilms, it is preferable that the bubbles contain little oxygen. It is preferable that the bubble generator 300 be equipped with a gas supply structure, taking into consideration the enhancement of the desired effect.

[0110] The bubble generator 300 shown in Figure 6 may be provided with a gas supply structure (not shown) as described above. The gas supply structure is a structure that introduces gas into the liquid channel 122 from the outside. Preferably, the gas supply structure is configured so that the conditions of the gas introduced into the liquid channel 122 from the outside can be determined according to the effects required of the gas-liquid mixture, as described above. When the bubble generator 300 is provided with a gas supply structure that takes in gas from the outside (for example, nitrogen or carbon dioxide) into the liquid channel 122, the supplied gas flows toward the downstream end 126 in the form of bubbles in the raw material liquid at the point of introduction, in accordance with the flow of the raw material liquid. Furthermore, bubbles formed by the gas supplied to the raw material liquid via the gas supply structure are finely divided in gaps and segment regions by collisions between the collision body 124 and the bubbles, and are further miniaturized. As a result, the bubble generator 300 can generate bubbles with a diameter of less than 1 μm, for example.

[0111] [5. Example of operation of the cleaning management system] The operation of the cleaning management system 100 includes a measurement operation, a cleaning operation, and a cleaning execution management operation. The measurement operation is an operation to measure the surface of the object to be cleaned M. The cleaning operation is an operation to clean the object to be cleaned. The cleaning execution management operation is an operation to store the details of the cleaning execution. In this specification, the timing of the measurement operation, cleaning operation, and cleaning execution management operation may be the same or different. The measurement operation, cleaning operation, and cleaning execution management operation may be performed separately and sequentially. Alternatively, the measurement operation, cleaning operation, and cleaning execution management operation may not be distinguished. For example, the cleaning operation and the measurement operation may proceed simultaneously.

[0112] The operation examples of the cleaning management system 100 will be described, including the measurement operation, the cleaning content determination operation, the cleaning operation, and the cleaning execution management operation. The explanation will proceed in the order of the first embodiment of the operation example and the second embodiment of the operation example.

[0113] The explanation of the operation example of the cleaning management system 100 will continue using the example shown in Figure 1. Furthermore, the explanation of the operation example of the cleaning management system 100 will be given as an example in which the measuring device 20 is configured to perform fluorescent X-ray analysis and the cleaning material is a gas-liquid mixture.

[0114] (5-1. First Embodiment of Operation Example) In the first embodiment of the operation example of the cleaning management system 100, the cleaning content is determined according to the type of element. In the first embodiment of the operation example of the cleaning management system 100, the measurement operation, cleaning operation, and cleaning execution management operation are performed, for example, as shown below. In the first embodiment, the measurement operation, cleaning operation, and cleaning execution management operation are performed sequentially in this order. However, this is just one example. The order and timing of the measurement operation, cleaning operation, and cleaning execution management operation do not have to be the order and timing described above, as will be described in the modified version of the first embodiment described later.

[0115] (5-1-1. Measurement Operation) In the cleaning management system 100, the measurement operation can be performed by the measuring device 20. The measuring device 20 measures the surface of the object to be cleaned M with the measuring unit 21. The measuring device 20 irradiates the measurement area m of the object to be cleaned M with X-rays from an energy ray irradiation unit (not shown). The sensor 21A of the measuring unit 21 detects fluorescent X-rays. Fluorescent X-rays are generally produced when X-rays are irradiated onto chemical substances attached to the surface of the object to be cleaned M. The measuring unit 21 sends the information of the fluorescent X-rays detected by the sensor 21A to the measurement information processing unit 22. The information of the fluorescent X-rays includes spectral waveform information. However, the information of the fluorescent X-rays may also include information on the peak wavelength in the spectral waveform and information on the light intensity corresponding to the peak wavelength. Information to identify each measurement area m may be stored in the database of the storage unit 12. Furthermore, for example, the measurement data measured in measurement area m1 may be stored in a database in the cleaning management device 10 for storing data obtained from measurements in measurement area m1.

[0116] The measurement information processing unit 22 identifies the type of element according to the light wavelength information contained in the received fluorescent X-ray information. For example, an element determination data table is constructed in the ROM of the measurement information processing unit 22, associating light wavelengths with element types. The CPU of the measurement information processing unit 22 then compares the spectral waveform information contained in the received fluorescent X-ray information with the information stored in the element determination data table. This allows the measurement information processing unit 22 to identify the type of element. The CPU of the measurement information processing unit 22 only needs to identify the type of at least one element contained in the chemical substance adhering to the surface of the object to be cleaned M. The CPU of the measurement information processing unit 22 may identify two or more types of elements. In this way, the measuring device 20 obtains information on the identified type of element. The identified type of element information is information on the type of at least one element contained in the chemical substance adhering to the surface of the object to be cleaned M.

[0117] The chemical substances measured by the measuring device 20 as chemical substances adhering to the surface of the object to be cleaned M are metal compounds. The type of element identified by the measuring device 20 is selected from the first group of elements described above. However, this is just an example, and the type of element identified by the measuring device 20 may be selected from the second group of elements described above. In this case, the type of element identified by the measuring device 20 may also be selected from a group that combines the first and second groups of elements described above.

[0118] The measuring device 20 transmits information about the type of element identified to the outside from a measurement information transmission unit (not shown). This information about the type of element identified is referred to as element type information. For example, the measuring device 20 may transmit the element type information to at least one of the cleaning device 30 and the cleaning management device 10. However, this is just one example. The measuring device 20 may also display the element type information on a measurement information display unit (not shown). In this case, the measuring device 20 does not need to transmit information about the type of element identified (element type information) to the outside. In this way, the measuring device 20 performs the function of measuring the surface of the object to be cleaned. As a result, the measuring device 20 realizes the measurement operation in the cleaning management system 100.

[0119] Thus, in the cleaning management system 100, the measuring device 20 operates to perform a function of measuring the surface of the object to be cleaned M. The measuring device 20 may perform the surface measurement of the object to be cleaned M again after the cleaning operation.

[0120] (5-1-2. Cleaning Operation) In the cleaning management system 100, the cleaning operation can be realized by the cleaning device 30. The cleaning device 30 releases (sprays) cleaning material from the nozzle of the cleaning unit toward the object to be cleaned M. In the cleaning device 30, the cleaning execution information processing unit may determine the cleaning execution content after starting the cleaning of the object to be cleaned M and upon completion of the cleaning. The cleaning execution content represents a combination of various cleaning execution conditions associated with the cleaning content of the object to be cleaned M and execution information associated with each cleaning execution condition. For example, examples of cleaning execution conditions include conditions such as discharge pressure, discharge time, and discharge volume. Examples of execution information include various types of information such as Va (MPa) for information associated with discharge pressure, Ta (min) for information associated with discharge time, and Wa (Kg) for information associated with discharge volume. The type of cleaning execution conditions determined by the cleaning execution information processing unit of the cleaning device 30 may be stored in the cleaning execution information processing unit of the cleaning device 30 in advance, or it may be input from the cleaning information input unit.

[0121] The cleaning details information may include time information such as the date and time the cleaning was performed, and / or environmental information such as the weather and temperature at the time the cleaning was performed. The cleaning details information may also include information about the person who performed the cleaning. Examples of information about the person who performed the cleaning include the name of the person who performed the cleaning, their affiliation, their cleaning experience, and information such as the person responsible for managing the cleaning operation.

[0122] The cleaning device 30 may be configured to transmit cleaning information from the cleaning information communication unit to the cleaning management device 10. Alternatively, the cleaning device 30 may display the cleaning information on the cleaning information display unit. In this case, the cleaning device 30 may omit transmitting the cleaning information to the cleaning management device 10.

[0123] In this way, the cleaning device 30 realizes the cleaning operation in the cleaning management system 100.

[0124] The cleaning device 30 may perform cleaning of the object to be cleaned M according to the planned cleaning content. The planned cleaning content can be the same as the cleaning execution content. The planned cleaning content represents a combination of various planned information associated with the planned cleaning conditions. The planned cleaning conditions represent the cleaning conditions planned when cleaning the object to be cleaned M. The planned information represents specific numerical values ​​and other information corresponding to each planned cleaning condition. Examples of planned cleaning conditions may include the same conditions as those listed in the examples of cleaning execution conditions. Examples of planned information may include the same types of information as those listed in the examples of execution information. The cleaning device 30 may store the planned cleaning content in advance in the cleaning execution information processing unit, or it may be input from the cleaning information input unit. It is preferable that the cleaning execution content matches the planned cleaning content. However, the planned cleaning content and the cleaning execution content may differ. For example, in such a case, the cleaning execution information processing unit may receive input information to change the cleaning conditions before the cleaning of the object to be cleaned M under the cleaning conditions corresponding to the planned cleaning content is completed.

[0125] (5-1-4. Cleaning Implementation Management Operation) The cleaning implementation management operation is an operation to store information corresponding to the cleaning implementation details described later in the storage unit 12, associating it with element type information. The cleaning implementation details are determined when the cleaning device 30 performs the cleaning operation described later. The information corresponding to the cleaning implementation details is referred to as cleaning implementation details information.

[0126] As shown in Figure 7, the control unit 16 of the cleaning management device 10 receives element type information transmitted from the cleaning device 30 via the communication unit 11 (step S71). The cleaning management device 10 may also receive information corresponding to the element type information from the input unit 14. As a result, the control unit 16 of the cleaning management device 10 acquires the element type information. In this way, the control unit 16 of the cleaning management device 10 functions as an element type information acquisition unit 10A.

[0127] As shown in Figure 7, the control unit 16 of the cleaning management device 10 receives cleaning execution information transmitted from the cleaning device 30 via the communication unit 11. The cleaning management device 10 may also receive information corresponding to the cleaning execution information from the input unit 14. As a result, the control unit 16 of the cleaning management device 10 acquires the cleaning execution information. In this way, the control unit 16 of the cleaning management device 10 functions as a cleaning execution information acquisition unit 10B.

[0128] The control unit 16 acquires element type information and cleaning procedure information in that order.

[0129] The control unit 16 of the cleaning management device 10 associates element type information with cleaning execution content information (step S72). That is, the control unit 16 of the cleaning management device 10 determines cleaning management information as information that associates element type information with cleaning execution content information. For example, the cleaning execution content information is associated by associating the most recently acquired cleaning execution content information with the most recently acquired element type information in the control unit 16. However, this is just one example.

[0130] In the cleaning management device 10, the control unit 16 may add identification information (such as ID information) to the element type information and transmit association information, which is associated with the identification information added to the element type information, to the cleaning device 30. In this case, the cleaning execution information processing unit in the cleaning device 30 adds the association information to the cleaning execution content information. The control unit 16 of the cleaning management device 10 acquires the cleaning execution content information to which such association information has been added, and by comparing the identification information with the association information, it can associate the element type information with the cleaning execution content information. In addition, the output unit 13 of the cleaning management device 10 may output the association information. In this case, the cleaning execution information processing unit in the cleaning device 30 may acquire the association information input from the cleaning information input unit. The association information may have the same content as the identification information or it may have different content. Matching such identification information with association information to associate the element type information with the cleaning execution content information can also be applied to the second embodiment and its modified versions in the operation example described later. In this way, the control unit 16 functions as a cleaning management information determination unit 10C.

[0131] The storage unit 12 of the cleaning management device 10 stores the cleaning management information determined by the control unit 16 in the cleaning execution management database 12A (step S73). In this way, the storage unit 12 functions as a cleaning management storage unit 10D.

[0132] According to the cleaning management device 10, element type information and cleaning implementation details can be associated and stored in the cleaning implementation management database 12A of the storage unit 12. In this case, information indicating what kind of cleaning was actually performed based on the element type information and cleaning implementation details can be stored in the cleaning implementation management database 12A of the storage unit 12. Furthermore, by storing information in the cleaning implementation management database 12A that associates element type information and cleaning implementation details, information for identifying the types of elements that tend to adhere to the surface of the cleaning target M can be stored. In addition, information for identifying efficient cleaning methods for chemical substances adhering to the surface of the cleaning target M can be stored.

[0133] Thus, in the cleaning management system 100, the cleaning management device 10 performs the function of storing the details of the cleaning performed. Furthermore, the cleaning management device 10 can also operate to store in association the type of element measured by the measuring device 20 with the cleaning details, which are the results of the cleaning operation performed according to that type of element. According to the cleaning management system 100, it is possible to perform cleaning according to the chemical substances adhering to the surface of the object to be cleaned M. Furthermore, according to the cleaning management system 100, it is possible to accumulate the history of chemical substances adhering to the surface of the object to be cleaned M and the conditions under which the cleaning was performed. For this reason, the cleaning management system 100 enables more efficient cleaning management. For example, the combination of element type information and cleaning details obtained from the Nth measurement by the measuring device 20 is compared with the element type information obtained from the (N+1)th measurement by the measuring device 20. This makes it possible to grasp the effectiveness of the cleaning details included in the cleaning details information. For example, if the object to be cleaned M is cleaned with a predetermined cleaning details, it is possible to grasp information such as whether a large amount of chemical substances that were adhering before the previous cleaning are not adhering significantly before the next cleaning. Therefore, it is possible to determine whether the cleaning procedures tend to improve the effectiveness of the cleaning.

[0134] The description of the first embodiment of the above operation example was given for an example where one measurement area m is defined on the object to be cleaned M. The first embodiment of the operation example is not limited to this. In the first embodiment of the operation example, multiple measurement areas m1, m2, ... may be defined on the object to be cleaned M.

[0135] The measurement areas m1, m2, etc. are defined, for example, as follows. That is, as shown in Figure 1B, the surface of the object to be cleaned M is divided into multiple regions (partition regions D1, D2, etc.), and a measurement area is assigned to each partition region. For example, measurement area m1 is defined for partition region D1, measurement area m2 is defined for partition region D2, and so on, with the measurement areas for each partition region being defined sequentially. In the first embodiment of the operation example, the above-described measurement operation, cleaning content determination operation, cleaning operation, and cleaning implementation management operation may be performed for each measurement area m1, m2, etc. In Figure 1B, examples of measurement areas m1, m2, m3 are shown in the dashed lines for the sake of explanation. The size and other conditions of the measurement areas m1, m2, m3 are not limited to the example shown in Figure 1B.

[0136] For example, if the object to be cleaned M is an aircraft, the surface of the aircraft is divided into multiple compartmental areas: the surface of the wing (compartmental area D1), the surface of the wing-fuselage connection (compartmental area D2), and the surface of the aircraft's fuselage (compartmental area D3). A measurement area m1 is determined from the wing surface area. A measurement area m2 is determined from the surface of the wing-fuselage connection area. A measurement area m3 is determined from the surface of the fuselage. Then, a measurement operation and a cleaning content determination operation are performed for measurement area m1. The cleaning operation is performed on the wing surface, which is the compartmental area corresponding to measurement area m1 (compartmental area D1 in the example of Figure 1B). The cleaning content determined by the cleaning operation corresponding to measurement area m1 is stored in the cleaning execution management database 12A of the storage unit 12 by performing a cleaning execution management operation. The measurement operation, cleaning content determination operation, cleaning operation, and cleaning execution management operation performed for measurement area m1 are also performed for measurement areas m2 and m3, respectively. In this way, by defining multiple measurement areas m, the cleaning content can be determined according to the part of the cleaning target M, and cleaning can be performed according to the cleaning content corresponding to the part of the cleaning target M. Furthermore, when the cleaning execution management operation is performed, the cleaning content corresponding to the part of the cleaning target M is stored in the cleaning execution management database 12A of the storage unit 12.

[0137] Furthermore, the possibility of defining multiple measurement areas m1, m2, etc. for the cleaning target M described above can also be applied in the second embodiment and its modified versions described later in the operation example. In addition, the possibility of performing the measurement operation, cleaning content determination operation, cleaning operation, and cleaning implementation management operation described above for each of the measurement areas m1, m2, etc. can also be applied in the second embodiment and its modified versions described later in the operation example.

[0138] In the first embodiment of the operation example, the storage unit 12 may have a usage history database that stores the usage history of the object to be cleaned M. In this case, the control unit 16 can associate element type information, cleaning implementation details information, and usage history and store them in the cleaning implementation management database 12A of the storage unit 12. In this case, it becomes possible to accumulate information that further associates the usage history with the history of chemical substances adhering to the surface of the object to be cleaned M and the implementation conditions when cleaning was performed, thus enabling more efficient cleaning management. For example, the combination of element type information and cleaning implementation details obtained by the Nth measurement by the measuring device 20 is compared with the combination of element type information and usage history obtained by the (N+1)th measurement by the measuring device 20. This makes it possible to grasp the effectiveness of the cleaning implementation details included in the cleaning implementation details information. For example, when the object to be cleaned M is cleaned with predetermined cleaning implementation details, it is possible to grasp information such as whether a large amount of chemical substances that were adhering before the previous cleaning are not adhering as much before the next cleaning, while considering the usage history. Therefore, it is possible to grasp whether the cleaning implementation details tend to increase the effectiveness of cleaning. Furthermore, the possibility of constructing a usage history database in the storage unit 12 that stores the usage history of the items to be cleaned can also be applied in the second embodiment and its modified versions described later in the operation example.

[0139] (5-2. Modifications of the First Embodiment of the Operation Example) In the description of the first embodiment of the operation example above, the case in which the measurement operation, cleaning operation, and cleaning implementation management operation are performed in this order was described as an example. In the first embodiment of the operation example, the order of the measurement operation, cleaning operation, and cleaning implementation management operation does not have to be in the order described above. Also, the timing of the individual execution of the measurement operation, cleaning operation, and cleaning implementation management operation is not limited. The timing of the individual execution may be at an appropriate time. Modifications 1 and 2 of the first embodiment of the operation example may also be applied to the second embodiment of the operation example described later.

[0140] (Modification 1 of the First Embodiment of the Operation Example) In Modification 1 of the First Embodiment of the Operation Example, the cleaning operation, measurement operation, and cleaning execution management operation are performed in this order at appropriate timings. The operation details of the cleaning operation and measurement operation in this Modification 1 may be the same as the cleaning operation and measurement operation shown in the First Embodiment of the Operation Example described above, so a detailed explanation is omitted. The cleaning execution management operation in this Modification 1 may be the same as the cleaning execution management operation shown in the First Embodiment of the Operation Example described above, except that the control unit acquires cleaning execution content information and element type information in this order, so a detailed explanation is omitted.

[0141] (Modification 2 of the First Embodiment of the Operation Example) In Modification 2 of the First Embodiment of the Operation Example, the cleaning operation, measurement operation, and cleaning execution management operation are performed repeatedly. For example, in the First Embodiment of the Operation Example, the measurement operation, cleaning operation, and cleaning execution management operation are performed repeatedly. The individual measurement operation, cleaning operation, and cleaning execution management operation in this Modification 2 may be the same as the cleaning operation, measurement operation, and cleaning execution management operation shown in the First Embodiment of the Operation Example described above, so a detailed explanation is omitted.

[0142] (5-2. Second Embodiment of Operation Example) In the second embodiment of the operation example of the cleaning management system 100, the amount of an element is determined according to information associated with the amount of the element, and the amount of the element is associated with the cleaning execution content. In the second embodiment of the operation example of the cleaning management system 100, the measurement operation, cleaning operation and cleaning execution management operation are performed, for example, as shown below.

[0143] (Measurement Operation) In the measurement operation of the second embodiment of the operation example, the information of the fluorescent X-rays detected by the sensor 21A includes spectral waveform information, the peak wavelength in the spectral waveform, and information of the light intensity corresponding to the peak wavelength. Except for this point, the measurement operation of the second embodiment of the operation example includes the same operation as the measurement operation of the first embodiment of the operation example. For this reason, the measurement information processing unit 22 identifies the type of element according to the spectral waveform information contained in the received fluorescent X-ray information.

[0144] Furthermore, in the measurement operation of the second embodiment of the operation example, the measurement information processing unit 22 determines the type of element and the amount of that element based on the light intensity information and element type information at the peak wavelength in the spectral waveform. For example, a data table for determining elemental abundance is constructed in the ROM of the measurement information processing unit 22, which associates light intensity with the amount of element for each type of element. The CPU of the measurement information processing unit 22 then compares the light intensity information contained in the received fluorescent X-ray information with the information stored in the data table for determining elemental abundance. As a result, the measurement information processing unit 22 identifies the type of element and the amount of that element.

[0145] The measuring device 20 transmits information about the type of element identified and the amount of that element to an external source (the cleaning management device 10 in the cleaning management system 100 of Figure 1). In the second embodiment of the operation example, as in the first embodiment of the operation example, the information about the type of element identified is referred to as element type information. Also, in the second embodiment of the operation example, the information about the amount of the element identified is referred to as element abundance information. However, the transmission of element type information and element abundance information as described above is just one example. As also explained in the first embodiment of the operation example, the measuring device 20 may display the element type information and element abundance information on a measurement information display unit (not shown). In this case, the measuring device 20 does not need to transmit the element type information and element abundance information to an external source.

[0146] The element abundance information and element type information are information about the type of element and information about the abundance of the element, which are identified by the measurement of the cleaning target M by the measuring device 20. The element abundance information and element type information can be identified by measurements performed at the same time. The specific element type included in the element type information and the specific element abundance included in the element abundance information are associated with each other. For example, when the measuring device 20 measures the cleaning target M at a predetermined timing and magnesium and calcium are detected by the measuring unit 21, the measurement information processing unit 22 determines information about magnesium and its abundance combination, and calcium and its abundance combination. In this way, the element abundance information and element type information are associated with each measurement by the measuring device 20.

[0147] In the second embodiment of the operation example, the cleaning operation is the same as the cleaning operation in the first embodiment of the operation example, so a detailed explanation is omitted.

[0148] (Cleaning execution management operation) In the second embodiment of the operation example, the cleaning execution management operation is an operation in which information corresponding to the cleaning execution content is stored in the storage unit 12 in association with element type information and element abundance information.

[0149] In the second embodiment of the operation example, the control unit 16 of the cleaning management device 10 receives element type information transmitted from the cleaning device 30 via the communication unit 11, similar to the first embodiment of the operation example. The cleaning management device 10 may also receive information corresponding to the element type information from the input unit 14. As a result, the control unit 16 of the cleaning management device 10 acquires the element type information. In this way, the control unit 16 of the cleaning management device 10 functions as an element type information acquisition unit 10A.

[0150] The control unit 16 of the cleaning management device 10 receives element abundance information transmitted from the cleaning device 30 via the communication unit 11. The cleaning management device 10 may also receive information corresponding to the element abundance information from the input unit 14. As a result, the control unit 16 of the cleaning management device 10 acquires the element abundance information. Note that the element type information and element abundance information may be separate information or integrated information. Integrated information is information that is transmitted and received as a set of element type information and element abundance information. In this way, the control unit 16 of the cleaning management device 10 functions as an element abundance corresponding information acquisition unit that acquires element abundance information.

[0151] The control unit 16 of the cleaning management device 10 receives cleaning execution information transmitted from the cleaning device 30 via the communication unit 11, similar to the first embodiment of the operation example. The cleaning management device 10 may also receive information corresponding to the cleaning execution information from the input unit 14. As a result, the control unit 16 of the cleaning management device 10 acquires the cleaning execution information. In this way, the control unit 16 of the cleaning management device 10 functions as a cleaning execution information acquisition unit 10B.

[0152] The control unit 16 acquires element type information and element abundance information before acquiring cleaning procedure information.

[0153] The control unit 16 of the cleaning management device 10 determines cleaning management information as information that associates element type information, element abundance information, and cleaning implementation details. For example, the cleaning implementation details are associated by associating the most recently acquired cleaning implementation details with the most recently acquired element type information in the control unit 16. Element abundance information is associated with the element type information as information about the abundance of the element type corresponding to the element type information. Therefore, the control unit 16 can determine information that associates element type information, element abundance information, and cleaning implementation details. This is just one example, and as described in the first embodiment of the operation example above, the element type information and cleaning implementation details may be associated by comparing identification information and association information. The association between element type information and element abundance information may also be achieved by comparing identification information and association information, similar to the association between element type information and cleaning implementation details. In this way, the control unit 16 functions as a cleaning management information determination unit 10C.

[0154] The storage unit 12 of the cleaning management device 10 stores the cleaning management information determined by the control unit 16 in the cleaning execution management database 12A, similar to the first embodiment of the operation example. In this way, the storage unit 12 functions as a cleaning management storage unit 10D.

[0155] According to the second embodiment of the operation example of the cleaning management system 100, element type information, element abundance information, and cleaning execution content information can be stored in the cleaning execution management database 12A of the storage unit 12 in association with each other, thus achieving the same effects as the first embodiment.

[0156] Furthermore, according to the second embodiment of the operation example of the cleaning management system 100, it becomes possible to perform cleaning according to the amount of chemical substance adhering to the surface of the object to be cleaned M, thereby enabling more efficient cleaning.

[0157] (5-3. Modifications of the second embodiment of the operation example) In the second embodiment of the operation example of the cleaning management system 100, for example, the following modifications may be adopted. The modifications will be described in the order of Modification 1, Modification 2, Modification 3, Modification 4, Modification 5, Modification 6, Modification 7, and Modification 8.

[0158] (Modification 1 of the second embodiment of the operation example) In Modification 1 of the second embodiment of the operation example of the cleaning management system 100, a cleaning necessity determination operation is performed. The cleaning necessity determination operation is an operation that determines whether or not the cleaning target M needs to be cleaned according to the amount of each element corresponding to the type of element. The description of one embodiment of Modification 1 of the second embodiment of the operation example of the cleaning management system 100 will continue. In the following description, we will take as an example the case in which a cleaning necessity determination database 12B as shown in Figure 5 is constructed in the storage unit 12 of the cleaning management device 10.

[0159] In Modification 1 of the second embodiment of the operation example, the measuring device 20 performs a measurement operation. The measurement operation is the same as in the second embodiment described above, so its explanation is omitted. In Modification 1 of the second embodiment of the operation example, the measurement operation is performed before the cleaning operation.

[0160] (Cleaning Requirement Determination Operation) The control unit 16 of the cleaning management device 10 receives element type information and element abundance information from the cleaning device 30 via the communication unit 11. The cleaning management device 10 may also receive information corresponding to the element type information and / or information corresponding to the element abundance information from the input unit 14. As a result, the cleaning management device 10 acquires element type information and element abundance information.

[0161] The element abundance information included in the element abundance information is associated with the type of element. The control unit 16 acquires the element abundance information associated with each type of element by acquiring the element type information and the element abundance information. For example, when the control unit 16 acquires information on magnesium and calcium as element type information, the control unit 16 acquires information on the abundance associated with magnesium (i.e., the amount of magnesium) and information on the abundance associated with calcium (i.e., the amount of calcium) as the amount information included in the element abundance information. The control unit 16 reads a judgment criterion value corresponding to the type of element according to the element type information from the cleaning necessity determination database 12B. The judgment criterion value is a threshold value for determining whether or not cleaning is necessary for the cleaning target M. For example, when the control unit 16 acquires information on magnesium and calcium as element type information, it reads the judgment criterion value MS2 associated with magnesium and the judgment criterion value MS3 associated with calcium from the cleaning necessity determination database 12B, as shown in Figure 5.

[0162] The control unit 16 determines whether or not to clean the object to be cleaned M by comparing the amount of element determined according to the type of element with a judgment criterion value corresponding to that type of element. For example, if the control unit 16 acquires magnesium information as element type information, the control unit 16 compares the amount of magnesium acquired from the element amount information with the judgment criterion value MS2 shown in Figure 5 to determine whether or not to clean the object to be cleaned M. Specifically, for example, the control unit 16 determines that the object to be cleaned M needs to be cleaned if the amount of magnesium exceeds the judgment criterion value MS2. The control unit 16 determines that the object to be cleaned M does not need to be cleaned if the amount of magnesium is less than or equal to the judgment criterion value MS2. In this way, the control unit 16 functions as a cleaning necessity determination unit that determines whether or not to clean the object to be cleaned M.

[0163] Furthermore, if there are multiple types of elements corresponding to the element type information, the control unit 16 may compare the amount of each element with the judgment criterion value. For example, if the control unit 16 acquires information on magnesium and calcium as element type information, the control unit 16 will perform the same procedure for calcium as it did for magnesium, where it determined whether cleaning of the cleaning target M was necessary by comparing the amount of magnesium with the judgment criterion value. That is, the control unit 16 will determine whether cleaning of the cleaning target M is necessary by comparing the amount of calcium obtained from the element amount information with the judgment criterion value MS3. Specifically, for example, the control unit 16 will determine that cleaning of the cleaning target M is necessary if the amount of calcium exceeds the judgment criterion value MS3. The control unit 16 will determine that cleaning of the cleaning target M is unnecessary if the amount of calcium is less than or equal to the judgment criterion value MS3. In this example, the control unit 16 will determine that cleaning of the cleaning target M is necessary if either the amount of magnesium or calcium exceeds the judgment criterion value. Thus, when the control unit 16 of the cleaning management device 10 compares the amount of each of several types of elements with the judgment criterion value, the control unit 16 may determine that cleaning of the object to be cleaned M is necessary if the amount of at least one type of element exceeds the judgment criterion value. However, this is just one example. The criteria for determining whether or not cleaning of the object to be cleaned M is necessary are not limited to the above.

[0164] In the cleaning management device 10, information corresponding to the determination result of whether or not the cleaning target M needs to be cleaned (referred to as cleaning necessity determination result information) is stored in the storage unit 12.

[0165] The cleaning management device 10 may also display the cleaning necessity determination result information on the output unit 13. In this case, the cleaning management device 10 does not need to store the cleaning necessity determination result information in the storage unit 12. The cleaning management device 10 may also transmit the cleaning necessity determination result information from the communication unit 11 to the cleaning device 30. In this case as well, the cleaning management device 10 does not need to store the cleaning necessity determination result information in the storage unit 12.

[0166] In Modification 1 of the second embodiment of the operation example, the cleaning device 30 performs a cleaning operation. The cleaning operation is the same as in the second embodiment described above, so its explanation is omitted.

[0167] In Modification 1 of the Second Embodiment of the Operation Example, the cleaning management device 10 performs a cleaning execution management operation. The cleaning execution management operation is the same as in the second embodiment described above, so its explanation is omitted.

[0168] In addition, in Modification 1 of the second embodiment of the operation example, the cleaning execution management operation may be omitted.

[0169] According to Modification 1 of the second embodiment of the operation example, it is possible to determine whether or not the object to be cleaned M needs to be cleaned depending on the type and amount of elements attached to the object to be cleaned M.

[0170] (Modification 2 of the second embodiment of the operation example) In modification 2 of the second embodiment of the operation example of the cleaning management system 100, the cleaning management device 10 performs the cleaning content determination operation. In this case, the cleaning management system 100 may have a cleaning content database stored in the storage unit 12 of the cleaning management device 10 that stores cleaning content corresponding to the cleaning conditions of the object to be cleaned.

[0171] (Cleaning Content Determination Operation) The control unit 16 of the cleaning management device 10 reads cleaning management information obtained as a result of Modification 2 of the second embodiment of the operation example described above from the cleaning execution management database 12A. The control unit 16 selects predetermined cleaning management information as the cleaning content for the specified type of element. In this way, the control unit 16 functions as a cleaning content determination unit that determines the cleaning content (cleaning conditions).

[0172] The storage unit 12 of the cleaning management device 10 stores the cleaning management information selected by the control unit 16 in the cleaning content database. In this way, the storage unit 12 functions as a cleaning content storage unit that stores cleaning content (cleaning conditions).

[0173] According to Modification 2 of the Second Embodiment of the Operation Example of the Cleaning Management System 100, it becomes possible to pre-determine cleaning conditions that have been proven effective as cleaning content, thereby enabling more efficient cleaning.

[0174] (Modification 3 of the second embodiment of the operation example) In modification 3 of the second embodiment of the operation example, an operation to estimate the amount of sodium present is performed. The sodium present amount estimation operation is an operation in which the estimated amount of sodium attached to the surface of the object to be cleaned M is determined from the amount of potassium attached to the surface of the object to be cleaned M. In modification 3 of the second embodiment of the operation example, the measurement operation and the cleaning operation are the same as in the second embodiment described above, so their explanation is omitted.

[0175] The second embodiment of the operation example includes a cleaning execution management operation. The cleaning execution management operation in the second embodiment of the operation example is the same as that of the second embodiment described above, so its explanation is omitted.

[0176] (Sodium Abundance Estimation Operation) The operation to determine the washing content can be realized by the washing management device 10. In the washing management device 10, the communication unit 11 receives element type information and element abundance information from the measuring device 20 in the same operation as in the second embodiment described above. The washing management device 10 acquires at least potassium information as element type information and potassium abundance information as element abundance information. The washing management device 10 may also receive potassium information and potassium abundance information from the input unit 14.

[0177] The storage unit 12 of the washing management device 10 has a sodium estimation conversion database that stores information relating the amount of potassium present to the estimated amount of sodium. The control unit 16 then compares the information on the amount of potassium present with the information on the amount of potassium present that is associated with the estimated amount of sodium stored in the sodium estimation conversion database. As a result, the control unit 16 determines the estimated amount of sodium. In this way, the control unit 16 functions as a sodium presence estimation unit that determines the estimated amount of sodium.

[0178] The values ​​stored in the sodium estimation conversion database mentioned above can be specified, for example, as follows: When the object to be cleaned M is used in at least one of the following locations: in the sea, on the sea surface, and in the air above the sea, it can be estimated that the sodium and potassium adhering to the surface of the object to be cleaned M are mainly derived from seawater. It can be estimated that the chemical substances adhering to the surface of such an object to be cleaned M contain potassium and sodium in the same ratio as those contained in seawater. That is, when the amount of potassium is determined from the "light intensity information and elemental type information" obtained by measuring the object to be cleaned M, the estimated amount of sodium adhering to the surface of the object to be cleaned M can be determined according to the ratio of potassium and sodium contained in seawater. Therefore, specifically, the sodium estimation conversion database stores information that associates the amount of potassium with the estimated amount of sodium according to the ratio of potassium and sodium contained in seawater, for example.

[0179] In Modification 3 of the second embodiment of the operation example, since the estimated amount of sodium present can be determined, the cleaning method for removing sodium-containing chemical substances from the surface of the object to be cleaned M can be determined without directly measuring the amount of sodium present. Modification 1 of the second embodiment of the operation example is particularly effective when the object to be cleaned M has a history of use in or near the sea (when mainly chemical substances derived from seawater adhere to the surface of the object to be cleaned M).

[0180] (Modification 4 of the second embodiment of the operation example) In modification 4 of the second embodiment of the operation example, an operation to determine whether or not parts need to be replaced is performed. The operation to determine whether or not parts need to be replaced is an operation in which the need to replace parts of the object to be cleaned M is determined based on the amount of elements present on the surface of the object to be cleaned M.

[0181] In Modification 4 of the second embodiment of the operation example, the measurement operation, cleaning operation, and cleaning execution management operation are the same as those in the second embodiment of the operation example described above, so their explanation is omitted.

[0182] (Determination of whether parts need to be replaced) In the modified example 4 of the second embodiment of the operation example, the determination of whether parts need to be replaced can be realized as follows. A threshold database for determining whether parts need to be replaced is constructed in the storage unit 12 of the cleaning management device 10 as a database for determining whether parts need to be replaced from the storage unit 12. The threshold database for determining whether parts need to be replaced stores the type of element and a threshold value (referred to as the first threshold value) for determining whether parts need to be replaced.

[0183] The control unit 16 of the cleaning management device 10 acquires element type information and element abundance information, as described in the second embodiment of the operation example.

[0184] The control unit 16 determines the combination of element type and element abundance information according to element type information and element abundance information. The control unit 16 reads a first threshold corresponding to the determined element type from the threshold database for determining whether parts need to be replaced. The control unit 16 compares the element abundance with the first threshold. If the element abundance exceeds the first threshold, the control unit 16 determines that parts of the part to be cleaned M need to be replaced. If the element abundance is less than or equal to the first threshold, the control unit 16 determines that parts of the part to be cleaned M do not need to be replaced. In this way, the control unit 16 functions as a parts replacement necessity determination unit.

[0185] For example, if the control unit 16 receives information on magnesium as element type information and determines the value of the amount of magnesium present (let's call it value WA), it can determine whether or not parts of the object to be cleaned M need to be replaced, as shown below. That is, the control unit 16 reads the combination of magnesium and the first threshold (value TA) stored in the threshold database for determining whether or not parts need to be replaced, and compares value WA with value TA. If value WA is greater than value TA, the control unit 16 determines that parts of the object to be cleaned M need to be replaced. If value WA is less than or equal to value TA, the control unit 16 determines that parts of the object to be cleaned M do not need to be replaced.

[0186] Furthermore, if the control unit 16 receives information on multiple types of elements as element type information, it may compare the amount of each element with a first threshold. In this case, if the amount of at least one of the multiple types of elements exceeds the first threshold, the control unit 16 may determine that replacement of the parts of the cleaning target M is necessary. If the amount of a specific element is below the first threshold, the control unit 16 may determine that replacement of the parts of the cleaning target M is unnecessary.

[0187] For example, if the control unit 16 receives information on magnesium and calcium as element type information and determines the value of the amount of magnesium present (let's call it value WA) and the value of the amount of calcium present (let's call it value WB), it can determine whether or not parts of the object to be cleaned M need to be replaced, as shown below. That is, the control unit 16 reads out the combination of magnesium and a first threshold (let's call it value TA) stored in the threshold database for determining whether or not parts need to be replaced, and compares value WA with value TA. The control unit 16 also reads out the combination of calcium and a first threshold (let's call it value TB) stored in the threshold database for determining whether or not parts need to be replaced, and compares value WB with value TB. If value WA is greater than value TA or value WB is greater than value TB, the control unit 16 may determine that parts of the object to be cleaned M need to be replaced. If value WA is less than or equal to value TA and value WB is less than or equal to value TB, the control unit 16 may determine that parts of the object to be cleaned M do not need to be replaced.

[0188] The control unit 16 displays the result of the operation to determine whether or not parts replacement is necessary on the output unit 13. For example, if the control unit 16 determines that parts replacement is necessary for the cleaning target M, it displays information indicating that parts replacement is necessary on the output unit 13.

[0189] According to Modification 4 of the second embodiment of the operation example, it is possible to determine whether or not to replace the equipment of the object to be cleaned M depending on the type and amount of elements attached to the object to be cleaned M.

[0190] (Modification 5 of the second embodiment of the operation example) In modification 5 of the second embodiment of the operation example, a usage permission determination operation is performed. The usage permission determination operation is an operation in which the usage permission (permission to use or prohibition to use) of the object to be cleaned M is determined based on the amount of elements present on the surface of the object to be cleaned M.

[0191] In Modification 5 of the second embodiment of the operation example, the measurement operation, cleaning operation, and cleaning execution management operation are the same as those in the second embodiment of the operation example described above, so their explanation is omitted.

[0192] (Usage Permit Determination Operation) In Modification 5 of the second embodiment of the operation example, the usage permit determination operation can be the same as the part replacement necessity determination operation shown in Modification 4 of the second embodiment of the operation example described above, except that the usage permit determination operation uses the usage permit determination threshold database described above instead of the part replacement necessity determination threshold database. The usage permit determination threshold database is a database for determining whether or not to use from the storage unit 12. The usage permit determination threshold database stores information that associates the type of element with a threshold (referred to as the second threshold) for determining whether or not to use. The usage permit determination threshold database is constructed in the storage unit 12 of the cleaning management device 10.

[0193] The control unit 16 of the cleaning management device 10 acquires element type information and element abundance information, as described in the second embodiment of the operation example. The control unit 16 acquires a combination of element type and abundance from the element type information and element abundance information. The control unit 16 compares the element abundance with a second threshold depending on the element type. If the element abundance exceeds the second threshold, the control unit 16 determines that the use of the cleaning target M is prohibited. If the element abundance is less than or equal to the second threshold, the control unit 16 determines that the use of the cleaning target M is permitted. In this way, the control unit 16 functions as a usability determination unit.

[0194] The control unit 16 displays the result of the permission / denial determination operation on the output unit 13. For example, if the control unit 16 determines that the use of the item to be cleaned M should be prohibited, it displays information on the output unit 13 indicating that the use of the item to be cleaned M is prohibited.

[0195] According to Modification 5 of the second embodiment of the operation example, it is possible to determine whether or not the object to be cleaned M is usable depending on the type and amount of elements attached to the object to be cleaned M.

[0196] (Modification 6 of the second embodiment of the operation example) In modification 6 of the second embodiment of the operation example, a usage history matching operation is performed to associate the usage history of the item to be cleaned with the cleaning management information. In this case, in the cleaning management system 100, a usage history database storing the usage history of the item to be cleaned may be constructed in the storage unit 12 of the cleaning management device 10.

[0197] In Modification 6 of the second embodiment of the operation example, the measurement operation, cleaning operation, and cleaning execution management operation are the same as those in the second embodiment of the operation example described above, so their explanation is omitted.

[0198] (Usage history matching operation) The control unit 16 of the cleaning management device 10 determines the cleaning management information by the same operation as in the second embodiment of the operation example described above. The control unit 16 reads the usage history information from the usage history database. The control unit 16 associates the read usage history information with the cleaning management information. The storage unit 12 stores the cleaning management information that has been associated with the usage history information.

[0199] According to Modification 6 of the second embodiment of the operation example, the types and amounts of elements attached to the object to be cleaned M can be associated with the usage history of the object to be cleaned M, and information can be accumulated to determine what elements will be attached to the object to be cleaned M under what kind of usage history.

[0200] (Modification 7 of the first embodiment of the operation example) In the second embodiment of the operation example, the order and timing of the measurement operation, cleaning operation and cleaning execution management operation do not have to be the order and timing of the measurement operation, cleaning operation and cleaning execution management operation. In Modification 7 of the second embodiment of the operation example, the cleaning operation, measurement operation and cleaning execution management operation are performed in this order and at appropriate timings. In Modification 7 of the second embodiment of the operation example, the operation contents of the cleaning operation and measurement operation may be the same as the cleaning operation and measurement operation shown in the second embodiment of the operation example described above, so a detailed explanation is omitted. In Modification 7 of the second embodiment of the operation example, the cleaning execution management operation may be the same as the cleaning execution management operation shown in the second embodiment of the operation example described above, except that the control unit 16 acquires "element type information and element abundance information" after acquiring cleaning execution content information, so a detailed explanation is omitted.

[0201] (Modification 8 of the second embodiment of the operation example) In modification 8 of the first embodiment of the operation example, the cleaning operation, measurement operation, and cleaning execution management operation are performed repeatedly. For example, in the first embodiment of the operation example, the measurement operation, cleaning operation, and cleaning execution management operation are performed repeatedly. In modification 8 of the second embodiment of the operation example, the individual measurement operation, cleaning operation, and cleaning execution management operation may be the same as the cleaning operation, measurement operation, and cleaning execution management operation shown in the first embodiment of the operation example described above, so a detailed explanation is omitted.

[0202] Modifications 1 to 8 of the second embodiment of the operation example may be combined with each other.
