Description

[Technical Field]

[0001] The present invention relates to a moisture meter that measures the amount of moisture contained in a sample to be measured and determines the moisture percentage, i.e., a technology for conveniently setting measurement conditions suitable for each type of sample to be measured in a moisture meter that measures the moisture content of a sample, a moisture measurement system that uses this moisture meter technology, a user terminal used in this moisture measurement system, a moisture measurement method, and a program. [Background technology]

[0002] A moisture meter is an instrument used to measure the moisture content of a measurement target (sample). For example, a moisture meter that measures the moisture content of a sample such as grain by irradiating it with infrared rays and then heating and drying it is called an "infrared moisture meter," "heat-drying moisture meter," or "heat-drying infrared moisture meter," and is a measuring instrument that can easily implement the "heat-drying method," which is often used as an official moisture measurement method (see, for example, Patent Documents 1 and 2).

[0003] The infrared moisture meter does not specify the object to be measured, and is basically configured to include a sample dish 93, a load meter 95, and a heat source (heater) 97 as a measurement unit 90, as shown in Figure 19, and measures the moisture content before and after heating and drying. That is, in the infrared moisture meter, the sample S to be measured is placed in a sample dish 93, and the weight of the sample S before heat drying is measured using a load meter 95, and the weight of the sample S after heat drying by irradiation with infrared rays from a heat source 97 is also measured, and the moisture content of the sample S is determined from the change in mass due to evaporation of the moisture.

[0004] In such infrared moisture meters, the relationship between measurement time and measured value is such that the measurement will automatically stop when the moisture change falls within a specified value as shown in Figure 20. However, the measurement results vary depending on the drying temperature set. In other words, although the infrared moisture meter can easily achieve the official method, it may not be able to measure correctly depending on the measurement conditions set.

[0005] Regarding temperature control with an infrared moisture meter, you can select a measurement mode that allows for rapid or slow drying, or a measurement mode that allows you to freely set the drying temperature for each elapsed time. However, the measurement conditions, consisting of the drying temperature and measurement mode settings, are not uniform and differ depending on the type of sample being measured. Therefore, when measuring, it is important to set measurement conditions appropriate for the object (sample) being measured. However, there are many objects being measured, such as food, pharmaceuticals, construction materials, and industrial raw materials, and the number of measurement conditions is accordingly increasing. As a result, users often have to set the measurement conditions by trial and error in order to measure correctly.

[0006] Therefore, a means has been proposed that improves the convenience of setting measurement conditions in a moisture meter (see, for example, Patent Document 3). This means allows the user to input the measurement conditions into an external device and acquire the measurement conditions through communication with the external device, eliminating the need to input the measurement conditions into the moisture meter or to store the measurement conditions in advance in the moisture meter.

[0007] However, the above-mentioned means requires the user to input the measurement conditions for measuring the moisture content of a sample into an external device, and does not allow the user to set measurement conditions suitable for each type of sample to be measured without trial and error.

[0008] Therefore, it is desirable for the user to be able to easily set measurement conditions suitable for the object to be measured in a short time without trial and error, but as far as the applicant knows, such a moisture meter has not yet been proposed.

[0010] The present invention was developed in consideration of the above-mentioned conventional circumstances, and aims to provide a technology that enables convenient setting of measurement conditions suitable for each type of sample to be measured in a moisture meter that measures the moisture content of a sample. [Means for solving the problem]

[0011] In order to achieve the above-mentioned object, a first aspect of the present invention is a moisture meter for measuring the moisture content of a sample, comprising at least a memory means for storing measurement condition information for each type of sample, a display means for displaying sample information associated with the measurement condition information stored in the memory means, and a measurement means for measuring the moisture content of the sample, wherein the display means receives selection information for selecting one of the pieces of sample information to be displayed, and the measurement means identifies the measurement condition information stored in the memory means in accordance with the reception of the selection information by the display means, and performs moisture measurement of the sample based on the measurement condition information.

[0012] The moisture meter may further include a communication means for communicating with an external device, wherein the communication means receives selection information from the external device for selecting one of the measurement condition information stored in the storage means, and the measurement means identifies the measurement condition information stored in the storage means in accordance with the selection information received by the communication means, enabling moisture measurement of the sample to be performed based on the measurement condition information.

[0013] In addition, the moisture meter described above may further include a communication means for communicating with an external device, the communication means receiving update information about the measurement condition information from the external device, and the storage means updating the stored measurement condition information to the update information received by the communication means.

[0015] In the moisture measurement system described above, the moisture meter may be further communicatively connected via a network to a measurement condition management device that manages measurement condition information for each type of sample and an administrator terminal used by an administrator who updates the measurement condition information, wherein the moisture meter's communication means receives update information for the measurement condition information from the user terminal, and the storage means updates the measurement condition information it stores to the update information received by the communication means, and the user terminal further comprises means for confirming with the measurement condition management device whether or not the update information is available, means for receiving the update information from the measurement condition management device, means for updating the measurement condition information to the update information, and means for sending the update information to the moisture meter, and the measurement condition management device may at least comprise means for receiving the update information from the administrator terminal, means for storing the update information, means for receiving confirmation of the presence or absence of the update information from the user terminal, and means for sending the update information to the user terminal, and the administrator terminal may at least comprise means for sending the update information to the measurement condition management device.

[0016] Here, the term "update information" refers to information that includes new measurement conditions that have been changed (improved) by verifying known measurement conditions, as well as newly developed measurement conditions that are not known measurement conditions. Therefore, the term "update information" is a term (phrase) used to distinguish it from known measurement condition information by referring to new measurement condition information, so as not to confuse it with known measurement condition information, and both refer to measurement condition information.

[0017] In addition, in this case, in the above-mentioned moisture measurement system, the measurement condition information and the update information are provided with version information, and the measurement condition information is updated to the update information based on the version information.

[0018] Another aspect of the present invention is a user terminal used by a user who instructs a moisture meter to measure the moisture content of a sample, and which is characterized by having at least: a means for storing measurement condition information for each type of sample; a means for displaying sample information associated with each of the measurement condition information; a means for accepting selection information for selecting one of the sample information; and a means for transmitting the selection information to the moisture meter.

[0022] Each of the moisture measurement methods described above may further include the steps of receiving update information for the measurement condition information via communication, and updating the stored measurement condition information to the received update information.

[0023] Another aspect of the present invention is a program that causes a computer to perform the following functions: storing measurement condition information for each type of sample; displaying sample information associated with the measurement condition information; receiving selection information for selecting one of the sample information; identifying the measurement condition information in accordance with the reception of the selection information; and measuring the moisture content of the sample based on the identification of the measurement condition information.

[0024] Furthermore, another aspect of the present invention is a program that causes a computer to perform the following functions: storing measurement condition information for each type of sample; receiving selection information via communication to select one of the measurement condition information; identifying the measurement condition information in accordance with the reception of the selection information; and performing moisture measurement of the sample based on the identification of the measurement condition information.

[Effects of the Invention]

[0026] According to the present invention, the moisture meter stores in advance the measurement conditions suitable for each type of sample, and displays the sample information associated with each measurement condition. This allows the user to easily instruct the moisture measurement of a sample by selecting and setting any measurement condition from the measurement conditions derived in advance, without having to think about inputting difficult measurement conditions (i.e., without having to go through trial and error to input the measurement conditions). This eliminates the need to input measurement conditions into the moisture meter, and allows measurement conditions suitable for each type of sample to be measured to be set conveniently, easily, and in a short time.

[0028] As an example of an embodiment of the present invention, a heat-drying type infrared moisture meter that measures the moisture content of a sample by heating and drying the sample by irradiating it with infrared rays will be described below with reference to the drawings. The embodiments described below are preferred examples of the present invention and are therefore subject to various technical limitations. However, the scope of the present invention is not limited to these embodiments unless otherwise specified in the following description.

[0029] First Embodiment 1 and 2, a heat-drying type infrared moisture meter (hereinafter simply referred to as "moisture meter") 10 in this embodiment includes a housing 1 and an openable / closable lid 2 for housing 1. By closing this lid 2, a heating chamber is formed inside the sealed housing 1 in which the moisture content of a sample (measurement object) is measured.

[0030] A tray 4 is provided inside (heating chamber) of the housing 1. The tray 4 detachably holds a sample dish 3 on which a sample such as grain is placed. The tray 4 is disposed at the upper end of a measuring column 5a of the load meter 5. In other words, the tray 4 is connected to the load meter 5 via the measuring column 5a disposed on the underside.

[0031] The load meter 5 is a means for measuring the weight of the sample, and can be, for example, a mass (weight) sensor that detects the weight of the sample placed on the sample tray 3. Therefore, when the sample tray 3 with the sample placed thereon is set in the receiving tray 4, the load acting on the receiving tray 4 is detected by the load meter 5, and the weight of the sample can be measured.

[0032] The heating chamber is also provided with a lower windshield 6a and an upper windshield 6b. The lower windshield 6a is a cylindrical member that is open at the top and is fixed to the housing 1 so as to surround the sample dish 3 and the receiving dish 4. On the other hand, the upper windshield 6b is a cylindrical member that is open at the bottom and is disposed above the lower windshield 6a so as to be openable and closable. A heating unit 17 is provided inside the upper windshield 6b.

[0033] The heating unit 17 includes a heat source 7 and a thermometer 8 . The heat source 7 is a means for heating the inside of the heating chamber, and can be, for example, a heater such as a halogen lamp or a resistance wire that generates Joule heat. The thermometer 8 is a means for measuring the temperature inside the heating chamber, and can be, for example, a temperature sensor.

[0034] A heat source (heater) 7 is attached inside this upper windshield 6b so as to be parallel to the top surface of the sample dish 3, and a thermometer 8 is placed in a corner of the upper windshield 6b, diagonally above the sample dish 3. Therefore, in the heating section 17, the inside of the heating chamber (sample) is heated by the heat source 7 based on the output from the thermometer 8.

[0035] The display unit 9 is a means for displaying various information relating to the measurement, such as sample information, and is provided at the top of the front side of the housing 1 so that it can be easily viewed from the outside. Here, the sample information refers to, for example, the type or name of the sample, and is information that allows the measurement condition information to be identified from the sample information. That is, a plurality of pieces of measurement condition information are stored in advance in the storage unit in association with the sample information, and each piece of sample information associated with this measurement condition information is displayed on the display unit 9. The display unit 9 displays a plurality of pieces of sample information before the start of measurement as a list-type sample selection menu that allows one piece of sample information to be selected from among a plurality of pieces of sample information.

[0036] The display unit 9 is configured integrally with the instruction receiving unit 91. The instruction receiving unit 91 is a means for receiving an instruction to select one piece of sample information from among a plurality of pieces of sample information displayed on the display unit 9 as selection information, and functions as a selection button in the sample selection menu. This instruction receiving section 91 may also have the function of a measurement start button for issuing an instruction to start measurement.

[0037] Such a display unit 9 can be, for example, a liquid crystal touch panel display. Therefore, by touching (tapping) any of the sample information display areas in the sample selection menu displayed on the display unit 9, the selection button is pressed and the sample information can be selected. The display unit 9 also displays the measurement results after the measurement is completed.

[0038] FIG. 3 is a block diagram showing the hardware configuration of the moisture meter 10 according to this embodiment. As shown in FIG. 3, the moisture meter 10 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a bus 14, an input / output interface 15, the above-mentioned sample dish 3, a load meter 5, a heater (heat source) 7, a thermometer 8, a touch panel display 9, and a memory unit 18.

[0039] CPU 11 executes various processes according to programs stored in ROM 12 or programs loaded from storage unit 18 to RAM 13. That is, CPU 11 is a processor that executes various processes according to the programs and controls the operation of moisture meter 10. The programs are, for example, an operating system or firmware for operating each unit of moisture meter 10, or application software for implementing the functional blocks described below.

[0040] The RAM 13 also stores data necessary for the CPU 11 to execute various processes as needed. The CPU 11, ROM 12, and RAM 13 are interconnected via a bus 14. An input / output interface 15 is also connected to this bus 14. The input / output interface 15 is connected to a load meter 5, a heater 7, a thermometer 8, a touch panel display 9, and a storage unit 18.

[0041] The memory unit 18 stores various data in advance, such as measurement condition information appropriate for each type of sample to be measured, as information necessary for the moisture meter 10 to perform the moisture measurement process, and can be, for example, a non-volatile semiconductor memory such as a flash memory.

[0042] The moisture meter 10 may be provided with a drive to which removable media can be appropriately attached. This drive allows a program read from the removable media to be installed in the storage unit 18. Furthermore, the removable media can store various data stored in the storage unit 18 in the same manner as the storage unit 18.

[0043] FIG. 4 is a functional block diagram showing an example of the functional configuration of moisture meter 10 according to the present embodiment. As shown in FIG. 4, moisture meter 10 includes measurement unit 16, display unit 9, instruction receiving unit 91, memory unit 18, as well as sample information display unit 111, selection information receiving unit 112, measurement condition identification unit 113, measurement execution unit 114, and moisture content calculation unit 115.

[0044] When the CPU 11 operates, a sample information display unit 111, a selection information receiving unit 112, a measurement condition specifying unit 113, a measurement execution unit 114, and a moisture content calculation unit 115 function. In other words, the moisture meter 10 of this embodiment functions as a device including a sample information display unit 111, a selection information receiving unit 112, a measurement condition identification unit 113, a measurement execution unit 114, and a moisture content calculation unit 115, by loading various programs (OS, applications, etc.) stored in an auxiliary storage device (e.g., ROM) into a main storage device (RAM) and executing them by a CPU 11.

[0045] The measurement unit 16 is composed of a weight measurement unit (load meter) 5 and a heating unit 17, and identifies the measurement condition information stored in the memory unit 18 in accordance with the selection information received by the instruction receiving unit 91, which is integral with the display unit 9, and performs moisture measurement of the sample based on the measurement condition information.

[0046] The sample information display unit 111 is a means having a function of displaying sample information associated with measurement condition information. That is, the sample information display unit 111 displays on the display unit 9 sample information that can identify the measurement condition information stored in the memory unit 18, and for example, by turning on the power or pressing any button such as a measurement button (not shown), the sample information is displayed as a sample selection menu.

[0047] In this embodiment, the sample information can be displayed, for example, as shown in FIG. FIG. 5 is a schematic diagram showing an example of the configuration of a sample selection menu screen 100 displayed on the display unit 9. 5, a sample selection menu screen 100 displays a sample selection menu 102 together with an instruction message 101 saying "Please select measurement conditions." The sample selection menu 102 also displays information on a plurality of samples, such as "Sample A, Sample B, Sample C, Sample D, Sample E, Sample F," for example. For ease of explanation, the sample selection menu 102 displays sample A, sample B, etc. However, more specifically, it would be better if the menu displayed displayed names of samples to be measured, such as rice grains, brown rice, wheat, and soybeans.

[0048] The measurement condition information is, for example, as shown in FIG. FIG. 6 shows an example of measurement conditions that are set in advance in the moisture meter 10, where FIG. 6(A) shows the measurement conditions for sample A, FIG. 6(B) shows the measurement conditions for sample B, and FIG. 6(C) shows the measurement conditions for sample C. FIG. 6(A) shows that the measurement conditions for sample A were that it was heated at a temperature of 120°C for 3 minutes, and then continued to be heated at a temperature of 100°C. FIG. 6(B) shows that sample B was measured under conditions in which it was continuously heated at a temperature of 85°C. FIG. 6(C) shows that the measurement conditions for sample C were such that it was heated at a temperature of 100°C for 1 minute, and then continued to be heated at a temperature of 90°C.

[0049] The selection information receiving unit 112 is a means having a function of receiving selection information that specifies one of the pieces of sample information (sample selection menu). That is, the sample selection menu screen 100 displayed on the display unit 9 allows the user to select any piece of sample information by touching the portion where that piece of sample information is displayed. Therefore, the selection information receiving unit 112 receives the selection information (i.e., any one piece of sample information) received by the instruction receiving unit 91 when any sample information display portion is touched in the sample selection menu 102 displayed by the sample information display unit 111.

[0050] The measurement condition specifying unit 113 is a means having a function of specifying measurement condition information in accordance with the reception of selection information. In other words, the sample information displayed on the sample selection menu screen 100 is associated with measurement condition information appropriate for each corresponding sample, and by selecting any of the sample information, the corresponding measurement condition information can be identified. Therefore, the measurement condition specifying unit 113 refers to the storage unit 18 based on the selection information received by the selection information receiving unit 112, and specifies the corresponding measurement condition information.

[0051] The measurement execution unit 114 is a means having a function of executing measurement of the moisture content of a sample based on the specified measurement condition information. That is, the measurement execution unit 114 controls the measurement unit 16 based on the measurement condition information specified by the measurement condition specification unit 113, and executes the measurement. Therefore, the measurement execution unit 114 controls the measurement unit 16 to measure the mass of the sample before heating and drying when the measurement starts, and then to continue heating and drying the sample, and to measure the mass of the sample after heating and drying when the measurement ends.

[0052] The moisture content calculation unit 115 is a means having a function of calculating the moisture percentage of the sample based on the change in mass of the sample. That is, the moisture content calculation unit 115 calculates the moisture percentage by a known calculation method upon completion of the measurement by the measurement execution unit 114. Therefore, after the measurement by the measurement execution unit 114 is completed, the moisture content calculation unit 115 calculates the moisture content value (moisture percentage) based on the mass of the sample before heating and drying measured at the start of the measurement and the mass of the sample after heating and drying measured at the end of the measurement.

[0053] Next, the processing flow in the moisture meter 10 will be explained. FIG. 7 is a flowchart showing an example of the basic operation of the moisture measurement process according to the embodiment of the present invention. First, in step S101, the sample information display unit 111 performs processing to display a sample selection menu (sample information) on the touch panel display (display unit) 9 in response to a request from the user to perform measurement.

[0054] Next, in step S102, the selection information receiving unit 112 performs processing to determine whether or not it has received a selection of sample information (selection information) in the sample selection menu displayed by the sample information display unit 111. If the selection information receiving unit 112 has received the selection information (YES in S102), it proceeds to step S103; if not (NO in S102), it repeats the determination in step S102. Subsequently, in step S103, the measurement condition specifying unit 113 refers to the storage unit 18 based on the selection information received by the selection information receiving unit 112, and performs processing to specify the corresponding measurement condition information.

[0055] Then, in step S104, the measurement execution unit 114 controls the measurement unit 16 based on the measurement condition information identified by the measurement condition identification unit 113, and performs processing to execute the measurement. That is, the mass of the sample before heat drying is measured, and the temperature inside the heating chamber is controlled while heating the heating chamber (sample) based on the selected measurement conditions for the sample, and measurement is performed until the change (decrease) in the mass of the sample becomes constant.

[0056] In step S105, the measurement execution unit 114 performs a process of determining whether or not the measurement in the measurement unit 16 has finished. If the measurement execution unit 114 determines that the measurement has finished (YES in S105), the process proceeds to step S106; if not (NO in S105), the process in step S104 is repeated. That is, when the change in mass of the sample becomes constant, the heating is stopped, the measurement is completed, and the mass of the sample after heating and drying is measured.

[0057] Furthermore, in step S106, after the measurement is completed, the moisture content calculation unit 115 performs a predetermined calculation based on the mass of the sample before and after heat drying measured by the measurement execution unit 114 to calculate the moisture content (moisture content value) of the sample. Then, in step S107, the display unit 9 performs a process of displaying the information on the moisture percentage calculated by the moisture content calculation unit 115 on the touch panel display (display unit) 9. Thereafter, the series of operations in the moisture meter 10 ends (END).

[0058] As described above, in the moisture meter 10 of this embodiment, the measurement condition information suitable for each type of sample that has been derived in advance is stored in the moisture meter 10 in advance, and when measuring the moisture content of a sample, the user can simply select the desired sample information from the sample selection menu displayed on the display unit 9 in accordance with direct operation, thereby setting the measurement condition information associated with the sample information and performing the measurement. This eliminates the need to input measurement conditions into the moisture meter, eliminating the risk of setting the wrong measurement conditions and allowing for convenient setting of measurement conditions.

[0059] <Second embodiment> The present invention also makes it easier to set measurement conditions for a moisture meter. That is, the present invention differs from the first embodiment in that measurement conditions can be set via an external device that has a display larger than the display provided in the moisture meter and that can communicate with the moisture meter.

[0060] As an example of an embodiment of the present invention, a moisture measurement system (hereinafter referred to as "this measurement system") that sets measurement conditions for measuring the moisture content of a sample using an external device that is communicably connected via a network will be described below with reference to the drawings. In the following embodiment, the differences from the first embodiment will be mainly described. Therefore, the same components as those in the first embodiment will be denoted by the same reference numerals and the description thereof will be omitted, and they will be considered the same unless otherwise specified.

[0061] [System Configuration] FIG. 8 is a diagram showing an outline of the configuration of this measurement system. As shown in FIG. 8, this measurement system is made up of a moisture meter 20 that measures the moisture content of a sample, and an external device 30 that can communicate with the moisture meter 20.

[0062] As shown in Figures 9 and 10, the moisture meter 20 of this embodiment is the same as the moisture meter 10 described in the first embodiment, except that it further comprises a communication unit (communication function) 19.

[0063] The communication unit 19 is a communication interface that communicates with an external device via a network such as Bluetooth (registered trademark). When information is input through the communication unit 19, the communication unit 19 also functions as the instruction receiving unit 91 or the selection information receiving unit 112.

[0064] The external device 30 is a terminal (hereinafter referred to as a "user terminal") used by a user (measurer) who performs measurements using the moisture meter 20, and is configured, for example, by a computer device such as a smartphone, a notebook computer, a tablet computer, or a desktop computer. As described above, the user terminal 30 is configured to be connected to the moisture meter 20 via short-range wireless communication such as Bluetooth (registered trademark) so as to be able to communicate with each other.

[0065] [User device configuration] FIG. 11 is a block diagram showing the hardware configuration of the user terminal 30 according to this embodiment. The user terminal 30 includes a CPU (Central Processing Unit) 31, a ROM (Read Only Memory) 32, a RAM (Random Access Memory) 33, a bus 34, an input / output interface 35, a display unit 36, an input unit 37, a memory unit 38, and a communication unit 39.

[0066] The CPU 31 executes various processes according to a program stored in the ROM 32 or a program loaded from the storage unit 38 into the RAM 33 . That is, the CPU 31 is a processor that executes various processes in accordance with a program and controls the overall operation of the user terminal 30. The program is, for example, an operating system (system software) for operating each unit of the user terminal 30, or application software for realizing the functional blocks described below.

[0067] The RAM 33 also stores data and the like necessary for the CPU 31 to execute various processes. The CPU 31, ROM 32, and RAM 33 are interconnected via a bus 34. An input / output interface 35 is also connected to this bus 34. A display unit 36, an input unit 37, a storage unit 38, and a communication unit 39 are connected to the input / output interface 35.

[0068] The display unit 36 ​​is a means for displaying information, and is, for example, a display. The input unit 37 is a means for inputting various information to the user terminal 30, and is composed of a keyboard, mouse, camera, touch panel display, etc., and inputs various information in response to received instruction operations. For example, the display unit 36 ​​and the input unit 37 may be integrated into one unit using a touch panel display.

[0069] The storage unit 38 is a means for storing various data necessary for the user terminal 30 to execute information processing, and stores applications and other programs for executing moisture measurement processing in this measurement system. The communication unit 39 is a communication interface, and communicates with the moisture meter 20 via a network such as Bluetooth (registered trademark).

[0070] FIG. 12 is a block diagram illustrating an example of the configuration of a user terminal 30 that functions as an external device in this embodiment. As shown in FIG. 12, the user terminal 30 includes a display unit 36, an input unit 37, a storage unit 38, a communication unit 39, and a moisture content measurement processing unit 311.

[0071] When the CPU 31 operates, a moisture content measurement processing unit 311 functions. That is, the user terminal 30 used in this embodiment functions as a device including a moisture content measurement processing unit 311 by loading various programs (OS, applications, etc.) stored in an auxiliary storage device (e.g., ROM) into a main storage device (RAM) and executing them by a CPU 31.

[0072] Moisture content measurement processing unit 311 is a means having a function of displaying sample information associated with each measurement condition information. That is, moisture content measurement processing unit 311 displays sample information that can identify the measurement condition information stored in memory unit 18 of moisture meter 20 on display unit 36, and this sample information can be displayed, for example, as shown on user terminal 30 in FIG. 8.

[0073] FIG. 8 is also a schematic diagram showing an example of the configuration of the sample selection menu screen 130 displayed on the display unit 36 ​​of the user terminal 30. 8, the sample selection menu screen 130 displays a sample selection menu 131, a plurality of selection buttons 132 provided corresponding to each piece of sample information, a send button 133, and a cancel button 134. The sample selection menu 131 also displays, as an example, a plurality of pieces of sample information such as "Sample A, Sample B, Sample C, Sample D, Sample E, Sample F, and Sample G." The selection button 132 is displayed as if sample D has been selected. For ease of explanation, sample selection menu 131 is assumed to show sample A, sample B, etc., but as with moisture meter 20, the names of the samples to be measured, such as rice husks, brown rice, wheat, and soybeans, are actually shown.

[0074] The moisture content measurement processing unit 311 also has a function of accepting selection information for specifying one of the displayed pieces of sample information. That is, the sample selection menu screen 130 displayed on the display unit 36 ​​allows the user to select any piece of sample information by touching a selection button 132 provided in front of that piece of sample information. Therefore, when any of the selection buttons 132 in the displayed sample selection menu 131 is touched, the moisture content measurement processing unit 311 accepts the specified selection information (ie, selected sample information).

[0075] Furthermore, moisture content measurement processing unit 311 is a means having a function of transmitting the received selection information to moisture meter 20. That is, moisture content measurement processing unit 311 transmits the selected sample information to moisture meter 20 by selecting one of the samples from displayed sample selection menu 131 (by touching selection button 132) and then pressing send button 133.

[0076] In the moisture meter 20 , the communication unit 19 receives the sample information transmitted from the user terminal 30 . Then, just as in the first embodiment, when instruction receiving unit 91 or selection information receiving unit 112 receives selection information, measurement condition specifying unit 113 then refers to memory unit 18 to specify the corresponding measurement condition information based on the received selection information, and measurement execution unit 114 controls measurement unit 16 based on the specified measurement condition information to perform measurement. Then, moisture content calculation unit 115 calculates the moisture percentage of the sample based on the change in mass of the sample.

[0077] Next, the processing flow of the measurement system according to one embodiment of the present invention will be described. Here, a case will be described in which measurement conditions are set for the moisture meter 20 using the user terminal 30. FIG. 13 is a sequence diagram showing an example of information processing according to an embodiment of the present invention.

[0078] First, in order to enjoy the use of this measurement system, the user accesses the site of this measurement system using the communication function of the user terminal 30 and installs (downloads) dedicated application software onto the user terminal 30 in advance.

[0079] Then, in step S201, the user terminal 30 displays the sample selection menu (sample information) 131 on the display unit 36 ​​in response to a request from the user to perform measurement. Next, in step S202, the user terminal 30 selects sample information in the sample selection menu 131 displayed. Then, in step S203, the user terminal 30 transmits the selected sample information to the moisture meter 20.

[0080] In step S204, the moisture meter 20 receives the sample information transmitted from the user terminal 30 via the communication unit 19. Next, in step S205, moisture meter 20 refers to storage unit 18 based on the received sample information to identify measurement condition information. Subsequently, in step S206, the moisture meter 20 performs measurement according to the specified measurement condition information.

[0081] Thereafter, in step S207, moisture meter 20 calculates the moisture content of the sample based on the measurement results. Then, in step S208, moisture meter 20 displays the calculated moisture percentage on display unit 9.

[0082] Next, the processing flow in the moisture meter 20 in this measurement system will be described. FIG. 14 is a flowchart showing an example of the operation of the moisture measurement process according to the embodiment of the present invention. In step S301, the selection information receiving unit 112 performs a process of determining whether or not it has received the specimen information received by the communication unit 19. If the selection information receiving unit 112 has received the specimen information (YES in S301), it proceeds to step S302, and if not (NO in S301), it repeats the determination in step S301.

[0083] Next, in step S302, the measurement condition specifying unit 113 refers to the storage unit 18 based on the sample information received by the selection information receiving unit 112, and performs processing to specify the corresponding measurement condition information. Subsequently, the same processes as those in steps S104 to S107 in the first embodiment are carried out. That is, in step S303, similarly to step S104 described above, the measurement execution section 114 controls the measurement section 16 based on the measurement condition information identified by the measurement condition identification section 113 to perform a process of executing measurement.

[0084] Also, in step S304, similar to step S105 described above, the measurement execution unit 114 performs processing to determine whether or not the measurement in the measurement unit 16 has been completed. Also, in step S305, similar to step S106 described above, after the measurement is completed, the moisture content calculation unit 115 performs a predetermined calculation based on the mass of the sample before and after heat drying measured by the measurement execution unit 114 to calculate the moisture content (moisture content value) of the sample.

[0085] Then, in step S306, similar to step S107 described above, the display unit 9 performs processing to display the information on the moisture percentage calculated by the moisture content calculation unit 115 on the touch panel display (display unit) 9. Thereafter, the series of operations in the moisture meter 20 ends (END).

[0086] As described above, according to this measurement system, by installing a dedicated application in an external device (user terminal) 30 such as a smartphone and enabling communication between the moisture meter 20 and the user terminal 30, it becomes possible to select and set measurement conditions not only through operations on the moisture meter 20 itself but also through indirect operations via the user terminal 30. That is, the user terminal 30 stores the same measurement condition information as that stored in the moisture meter 20 using a dedicated application, and the user can select the measurement condition information using the user terminal 30 and set the measurement condition information for the moisture meter 20. Therefore, even if the display unit 9 of the moisture meter 20 is small or even if the user is located far from the moisture meter 20, the user can conveniently set the measurement conditions and instruct the execution of moisture measurement of the sample using the user terminal 30.

[0087] <Third embodiment> Furthermore, in the present invention, the measurement condition information stored in the moisture meter can be updated as needed. That is, the present embodiment differs from the first embodiment in that the measurement conditions can be set via an external device capable of communicating with the moisture meter, and the present embodiment differs from the second embodiment in that another external device is provided that allows the measurement condition information stored in the moisture meter to be updated.

[0088] Below, as an example of another embodiment of the present invention, a moisture measurement system (hereinafter referred to as "this update system") that updates measurement condition information stored in a moisture meter using an external device that is communicatively connected via a network will be described with reference to the drawings. In the following embodiments, the explanation will be focused on the differences from the above-mentioned embodiments. Therefore, the same components as those in the first and second embodiments will be assigned the same reference numerals and the explanation thereof will be omitted, and they will be considered the same unless otherwise specified.

[0089] [System Configuration] FIG. 15 is a diagram showing an outline of the configuration of the update system in which the measurement condition information according to this embodiment is updated. As shown in Figure 15, this update system is composed of a moisture meter 20 that measures the moisture content of a sample, a first external device 40 that can communicate with the moisture meter 20, a second external device 50 that can communicate with the first external device 40, and a third external device 60 that can communicate with the second external device 50.

[0090] The moisture meter 20 has the same configuration as the moisture meter 20 described in the second embodiment, and receives update information from the first external device 40 via the communication unit 19 and updates the measurement condition information stored in the memory unit 18.

[0091] The first external device 40 is a terminal (hereinafter referred to as a "user terminal") used by a user (measurer) who performs measurements using the moisture meter 20 and updates the measurement condition information stored in the moisture meter 20, and is configured, for example, by a computer device such as a smartphone, a notebook computer, a tablet computer, or a desktop computer.

[0092] This user terminal 40 is configured to be connected to the moisture meter 20 so that they can communicate with each other, for example, via short-range wireless communication such as Bluetooth (registered trademark), and is also configured to be connected to a second external device 50 so that they can communicate with each other, for example, via a network such as the Internet.

[0093] The second external device 50 is a server device (hereinafter referred to as the "measurement condition management device") that manages measurement condition information for each type of sample, and receives and stores update information from the third external device 60, as well as accepting confirmation (inquiry) from the user terminal 40 as to whether or not there is update information, and if there is update information, transmits the update information to the user terminal 40.

[0094] The measurement condition management device 50 is realized by an electronic device such as a desktop computer, a laptop computer, a tablet computer, or a smartphone, and functions as a server in the present update system. Furthermore, the measurement condition management device 50 is configured to be connected to a user terminal (first external device) 40 and a third external device 60 via a network such as the Internet so as to be able to communicate with each other.

[0095] The third external device 60 is a terminal used by an administrator who updates the measurement condition information (hereinafter referred to as the “administrator terminal”), and transmits (uploads) the update information to the measurement condition management device 50. The administrator who uses the administrator terminal 60 may be, for example, the provider of the moisture meter, who verifies previous measurement conditions, develops new measurement conditions, and provides aftercare after providing the moisture meter.

[0096] The administrator terminal 60 is realized by, for example, an electronic device such as a desktop computer, a laptop computer, a tablet computer, a smartphone, etc. The administrator terminal 60 is also configured to be connected to a measurement condition management device (second external device) 50 via a network such as the Internet so that they can communicate with each other.

[0097] As described above, in this update system, administrator terminal 60 provides (transmits) to measurement condition management device 50 update information that becomes new measurement condition information that is not stored in memory 18 of moisture meter 20. Furthermore, measurement condition management device 50 manages the update information received from administrator terminal 60 and provides (transmits) it to user terminal 40. Furthermore, user terminal 40 provides (transmits) the update information received from measurement condition management device 50 to moisture meter 20. Then, moisture meter 20 stores the update information received from user terminal 40 in memory 18 and performs measurement based on the updated measurement condition information (update information).

[0098] The network is a communication network used for data exchange between devices, and is not particularly limited. Therefore, the network may be, for example, a local area network (LAN) or a wide area network (WAN). The communication lines of the network may be wired or wireless, and both may be used.

[0099] [User device configuration] FIG. 16 is a block diagram illustrating an example of the configuration of a user terminal 40 that functions as a first external device in this embodiment. 16, the user terminal 40 according to this embodiment has a display unit 36, an input unit 37, a memory unit 38, a communication unit 39, as well as a moisture content measurement processing unit 311 and a measurement condition update processing unit 312. That is, the user terminal 40 further has the measurement condition update processing unit 312 in addition to the components of the user terminal 30 described in the second embodiment, and otherwise has the same configuration. When information is input through the communication unit 39, the communication unit 39 may also function as the input unit 37.

[0100] The measurement condition update processing unit 312 is a means having a function of checking the presence or absence of update information with respect to the measurement condition management device 50. In other words, the measurement condition update processing unit 312 queries the measurement condition management device 50 via the communication unit 39 as to whether or not there is new measurement condition information that the user terminal 40 itself does not store.

[0101] The measurement condition update processing unit 312 can be configured to, for example, access the measurement condition management device 50 and check (inquire) whether new information is available when dedicated application software that has been installed (downloaded) in advance is launched. In this case, it is advisable to confirm whether or not there is update information by, for example, assigning a version to the measurement condition information for each sample and checking based on this version information.

[0102] The measurement condition update processing unit 312 is a means having a function of receiving update information from the measurement condition management device 50. That is, when update information is found as a result of an inquiry to the measurement condition management device 50, the measurement condition update processing unit 312 acquires the update information from the measurement condition management device 50 and stores (updates) it in the storage unit 38.

[0103] Furthermore, measurement condition update processing unit 312 is a means having a function of transmitting update information to moisture meter 20. That is, after acquiring update information from measurement condition management device 50, measurement condition update processing unit 312 transmits the acquired update information to moisture meter 20. When moisture content measurement processing unit 311 transmits the selected information accepted to moisture meter 20, if the measurement condition information stored in user terminal 40 is newer than the measurement condition information stored in moisture meter 20, the update information may be transmitted to moisture meter 20 together with the sample information.

[0104] On the other hand, when the moisture meter 20 receives the update information transmitted from the user terminal 40, it updates the measurement condition information stored in the storage unit 18. Furthermore, when moisture meter 20 receives sample information and update information from user terminal 40, it updates the measurement condition information stored in storage unit 18, and measurement condition specification unit 113 subsequently specifies the relevant measurement condition information by referring to storage unit 18 based on the received selection information (sample information), just as selection information acceptance unit 112 did in the second embodiment when accepting selection information. Measurement execution unit 114 then controls measurement unit 16 to perform measurement based on the specified measurement condition information, and moisture content calculation unit 115 calculates the moisture percentage of the sample based on the change in mass of the sample.

[0105] Next, a process flow for setting measurement conditions using the update system according to one embodiment of the present invention will be described. FIG. 17 is a sequence diagram showing an example of information processing according to an embodiment of the present invention.

[0106] First, in order to enjoy using this system, the user accesses the site of this system using the communication function of the user terminal 40 and installs (downloads) dedicated application software onto the user terminal 30 in advance.

[0107] In step S401, the administrator terminal 60 transmits update information to the measurement condition management device 50. In addition, in step S402, the measurement condition managing device 50 receives the update information transmitted from the administrator terminal 60. Next, in step S403, the measurement condition management device 50 updates the measurement condition information stored therein.

[0108] On the other hand, in step S404, the user terminal 40 checks (inquires) the measurement condition management device 50 whether or not there is any updated information. In step S405, in response to confirmation from the user terminal 40, if there is update information, the measurement condition managing device 50 transmits the update information to the user terminal 40. In addition, in step S406, the user terminal 40 receives the update information transmitted from the measurement condition management device 50. Next, in step S407, the user terminal 40 updates the measurement condition information stored therein.

[0109] In step S408, the user terminal 40 displays a sample selection menu (sample information) based on the updated measurement condition information on the display unit 36 ​​in response to the request to perform measurement. Next, in step S409, the user terminal 40 accepts the selection of sample information from the displayed sample selection menu. Then, in step S410, the user terminal 40 transmits the selected sample information to the moisture meter 20.

[0110] Thereafter, as in the second embodiment described above, in step S411, moisture meter 20 receives the sample information transmitted from user terminal 40. At this time, if updated information is transmitted from user terminal 40, moisture meter 20 updates the measurement condition information stored therein. In step S412, moisture meter 20 refers to storage unit 18 based on the received sample information to identify measurement condition information. In step S413, the moisture meter 20 performs measurement according to the specified measurement condition information.

[0111] Then, in step S414, the moisture meter 20 calculates the moisture content of the sample based on the measurement results. Thereafter, in step S415, moisture meter 20 displays the calculated moisture percentage on display unit 9.

[0112] Next, the flow of processing at the user terminal 40 in this update system will be described. FIG. 18 is a flowchart showing an example of the operation of the measurement condition information update process according to the embodiment of the present invention. First, in order to enjoy the use of this update system, the user accesses the site of this update system using the communication function of the user terminal 40 and installs (downloads) the dedicated application software into the user terminal 30 in advance.

[0113] In step S501, the measurement condition update processing unit 312 performs processing to check (inquire) the measurement condition management device 50 about the presence or absence of update information in accordance with dedicated application software. Next, in step S502, the measurement condition update processing unit 312 performs processing to determine whether or not there is update information. If the measurement condition update processing unit 312 determines that there is update information (YES in S502), the process proceeds to step S503, and if not (NO in S502), the process proceeds to step S505.

[0114] In this case, the presence or absence of update information can be easily determined, for example, by comparing the version information of the measurement condition information managed (stored) by the measurement condition management device 50 with the version information of the measurement condition information stored by the user terminal 40.

[0115] Furthermore, in step S503, if the version information of the measurement condition information managed by the measurement condition management device 50 is newer than the version information of the measurement condition information stored in the user terminal 40, the measurement condition update processing unit 312 performs processing to receive the new measurement condition information as update information from the measurement condition management device 50. That is, the user terminal 40 requests new measurement condition information (update information) from the measurement condition management device 50 and receives the update information. In step S504, the measurement condition update processing unit 312 stores the received update information in the storage unit 38 and performs processing to update the measurement condition information.

[0116] Next, in step S505, the moisture content measurement processing unit 111 performs processing to display a sample selection menu (sample information) on the display unit 36 ​​in response to a measurement request from the user. Subsequently, in step S506, the moisture content measurement processing unit 111 performs a process of determining whether or not a selection of sample information (selected information) has been accepted in the sample selection menu 131 displayed on the display unit 36. If the moisture content measurement processing unit 111 has accepted the selected information (YES in S506), the process proceeds to step S507; if not (NO in S506), the process repeats the determination in step S506.

[0117] Then, in step S507, moisture content measurement processing unit 111 performs processing to transmit the selected sample information to moisture meter 20. After that, the series of operations at the user terminal 40 ends (END).

[0118] As described above, with this update system, by installing a dedicated application on an external device (user terminal) 40 such as a smartphone, it becomes possible to select and set measurement conditions and update the measurement condition information stored in the moisture meter 20 in accordance with operations on the moisture meter 20 itself as well as indirect operations via the user terminal 40.

[0119] In other words, the moisture meter 20 itself is shipped with the measurement condition information derived by the product provider pre-stored in it, but when the measurement condition information for each sample is revised (updated), this update system makes it easy to correct and update the measurement condition information stored in the moisture meter 20. Therefore, when performing moisture measurement, it is possible to increase the amount of measurement condition information and perform moisture measurement of a desired sample based on the latest upgraded measurement condition information.

[0120] Although one embodiment of the present invention has been described above, the above-described embodiment is merely an example for facilitating understanding of the present invention, and is not intended to limit the present invention. Furthermore, the present invention is not limited to the above-described embodiment, and any modifications, improvements, etc. that can achieve the object of the present invention are included in the present invention.

[0121] Furthermore, nothing in the present invention precludes the user from creating measurement conditions on moisture meters 10 and 20 or user terminals 30 and 40 . Furthermore, in the present invention, if the measurement condition information created by the user can be uploaded from the user terminal 30, 40 to the measurement condition management device (server) 50, it becomes possible for users at multiple locations within a company, for example, to share the measurement condition information with each other. [Industrial Applicability]

[0122] The moisture meter of the present invention can be used to measure the moisture content of grains and other foods, pharmaceuticals, construction materials, industrial raw materials, and the like. Furthermore, the moisture measurement system of the present invention makes it easier to set measurement conditions for a moisture meter, and can be used to update measurement condition information stored in the moisture meter.
