Description

Technical Field

[0001] The present invention relates to the technical field of ultraviolet disinfection, and more particularly to an automated dense sampling system, method and ultraviolet disinfection device using the same. Background Art

[0002] In recent years, numerous studies have demonstrated that UV disinfection is superior to manual disinfection in terms of both effectiveness and efficiency. In the field of UV disinfection technology, according to theoretical definitions, the irradiation dose is the cumulative integral of irradiance over time. UV irradiation dose is a key parameter affecting disinfection effectiveness. Therefore, accurately calculating and rationally controlling the irradiation dose is the core technology for achieving efficient disinfection in disinfection devices.

[0003] Existing near-field irradiance distribution detection schemes suffer from the following issues: high detection costs and low detection efficiency. Currently, there is no efficient and low-cost dense measurement solution. This makes it difficult to quickly and densely sample the irradiance distribution around the disinfection device, resulting in insufficient sampling data and, consequently, making it difficult to efficiently and cost-effectively compare the calculated values ​​of the disinfection device with the actual sampled values. This limitation hinders research on the irradiation dose of disinfection devices and product improvements.

[0004] The high detection cost of existing technologies is primarily due to the fact that point-by-point irradiance measurements in the near-field area of ​​UV lamps require a radiometer to be installed at each detection point. This requires a very large number of radiometers, and the cost of each radiometer is relatively high, significantly increasing the overall detection cost. Furthermore, the low detection efficiency of existing technologies means that if radiometers are used to measure each detection point one by one, the efficiency of the entire detection process will be very low. Summary of the Invention

[0005] In response to the technical problems raised in the background technology, the present invention aims to achieve efficient automated dense sampling at a lower cost through an automated dense sampling system and a dense sampling method, thereby solving the technical problem of how to provide more accurate irradiance distribution in a lower cost and efficient manner, which was difficult to achieve in the existing technology.

[0006] In order to solve the above technical problems, the present invention first provides the following technical solution 1:

[0007] An automated dense sampling method comprises the following steps:

[0008] S1. Preparation:

[0009] Selecting a tubular ultraviolet radiation source to be sampled, and selecting n ultraviolet irradiance measuring instruments, and arranging them in a two-dimensional plane where the center line of the tubular ultraviolet radiation source is located;

[0010] S2. Sampling work:

[0012] S2-1. Control n ultraviolet irradiance measuring instruments to scan each irradiance collection point in a preset measurement area within the first plane to obtain the current irradiance value of each irradiance collection point;

[0013] Controlling the plane where the n ultraviolet irradiance measuring instruments are located to rotate by a first preset angle relative to the first plane, with the center line of the tubular ultraviolet radiation source as the axis and the second plane as the rotation process;

[0014] Start the measurement of the preset measurement area in the second plane where n UV irradiance measuring instruments are currently located:

[0015] S2-2, controlling n ultraviolet irradiance measuring instruments to scan each irradiance collection point of a preset measurement area in the second plane to obtain the current irradiance value of each irradiance collection point;

[0016] Controlling the plane where the n ultraviolet irradiance measuring instruments are located to continue rotating by a first preset angle relative to the second plane, with the center line of the tubular ultraviolet radiation source as the axis during the rotation process, serving as the third plane;

[0017] Finally, sequentially controlling n ultraviolet irradiance measuring instruments to scan each irradiance collection point of a preset measurement area from the third plane to the m-th plane, so as to ultimately obtain an irradiance value at each irradiance collection point within a second preset angle in the near-field area of ​​the tubular ultraviolet radiation source;

[0018] or,

[0019] An automated dense sampling method comprises the following steps:

[0020] S1', preparation:

[0021] Selecting a tubular ultraviolet radiation source to be sampled, and selecting n ultraviolet irradiance measuring instruments, and arranging them in a cylindrical surface with the center line of the tubular ultraviolet radiation source as the axis;

[0022] S2', sampling work:

[0023] Start measuring the preset measurement area within the first cylindrical surface where n UV irradiance measuring instruments are currently located:

[0024] S2-1', control n ultraviolet light irradiance measuring instruments to scan each irradiance collection point in the preset measurement region in the first cylindrical surface, to obtain the irradiance value of each irradiance collection point at present;

[0025] Control the cylindrical surface where n ultraviolet light irradiance measuring instruments are located to change the first preset radius compared with the first cylindrical surface, as a second cylindrical surface;

[0026] Start the measurement work of the preset measurement region in the second cylindrical surface where n ultraviolet light irradiance measuring instruments are currently located:

[0027] S2-2', control n ultraviolet light irradiance measuring instruments to scan each irradiance collection point in the preset measurement region in the second cylindrical surface, to obtain the irradiance value of each irradiance collection point at present;

[0028] Control the cylindrical surface where n ultraviolet light irradiance measuring instruments are located to continue to change the first preset radius compared with the second cylindrical surface, as a third cylindrical surface;

[0029] Finally, control n ultraviolet light irradiance measuring instruments to scan each irradiance collection point in the preset measurement region in the third cylindrical surface to... the mth cylindrical surface in turn, to finally obtain the irradiance value of each irradiance collection point in the preset angle in the near-field region of the tubular ultraviolet light radiation source.

[0030] Through the above technical solution: the basic working principle of the automatic dense sampling method of the application is to control n ultraviolet light irradiance meters to efficiently and automatically scan each collection point in the near-field region, to obtain the irradiance value of each collection point, and to provide more accurate irradiance distribution of the near-field region.

[0031] And the scanning process mainly has two ideas, the first idea is: using n ultraviolet light irradiance meters distributed linearly to scan all collection points in the preset measurement region in the first two-dimensional plane in the direction perpendicular to the connecting line, to realize the detection of all collection points in the preset measurement region in the first two-dimensional plane; then control the first two-dimensional plane to rotate a preset angle to form a second two-dimensional plane... the mth plane, to realize the detection of all collection points in the near-field region in this cycle.

[0032] The second idea is: using n ultraviolet light irradiance meters arranged in a cylindrical surface to rotate and scan all collection points in the first cylindrical surface, to realize the detection of all collection points in the preset measurement region in the first cylindrical surface; then control n ultraviolet light irradiance meters to move along the radial direction, that is, let the first cylindrical surface change the first preset radius, to form a second two-dimensional cylindrical surface... the mth cylindrical surface, to realize the detection of all collection points in the near-field region in this cycle.

[0033] The present invention also provides the following technical solution 2:

[0034] An automated dense sampling system comprises: a tubular ultraviolet radiation source, n ultraviolet irradiance measuring instruments, a scanning controller, a rotation controller and a data server;

[0035] n ultraviolet irradiance measuring instruments are communicatively connected to a data server; the data server is used to receive irradiance values ​​measured by the n ultraviolet irradiance measuring instruments;

[0036] n ultraviolet irradiance measuring instruments are located in a two-dimensional plane where the center line of the tubular ultraviolet radiation source is located;

[0037] The scanning controller is connected to n ultraviolet irradiance measuring instruments or tubular ultraviolet radiation sources, and the scanning controller is used to control the n ultraviolet irradiance measuring instruments to scan each irradiance collection point of a preset measurement area in a two-dimensional plane to obtain an irradiance value at each irradiance collection point in the two-dimensional plane;

[0038] A rotation controller is connected to n ultraviolet irradiance measuring instruments or tubular ultraviolet radiation sources, and is used to control the two-dimensional plane where the n ultraviolet irradiance measuring instruments are currently located to rotate by a first preset angle relative to the two-dimensional plane where the n ultraviolet irradiance measuring instruments are previously located, with the center line of the tubular ultraviolet radiation source serving as the axis of the rotation process;

[0039] or,

[0040] An automated dense sampling system comprises: a tubular ultraviolet radiation source, n ultraviolet irradiance measuring instruments, a scanning controller, a rotation controller and a data server;

[0041] n ultraviolet irradiance measuring instruments are communicatively connected to a data server; the data server is used to receive irradiance values ​​measured by the n ultraviolet irradiance measuring instruments;

[0042] n ultraviolet irradiance measuring instruments are located in a cylindrical surface with the center line of the tubular ultraviolet radiation source as the axis;

[0043] The rotary controller is connected to n ultraviolet irradiance measuring instruments or tubular ultraviolet radiation sources, and the rotary controller is used to control the n ultraviolet irradiance measuring instruments to scan each irradiance collection point of a preset measurement area within the cylindrical surface to obtain the irradiance value of each current irradiance collection point;

[0044] The scanning controller is connected to n ultraviolet irradiance measuring instruments or tubular ultraviolet radiation sources, and is used to control the radius of the cylindrical surface at the current position of the n ultraviolet irradiance measuring instruments to increase or decrease the first preset radius compared with the radius of the cylindrical surface at the previous position.

[0045] Through the above technical solution: the automated dense sampling system of the present invention strikes a reasonable balance between sampling efficiency and system cost, and ultimately achieves more accurate irradiance numerical detection that is realistic and achievable.

[0046] The present invention further provides the following technical solution three:

[0047] The ultraviolet disinfection device includes a disinfection device body and an automated dense sampling system. The disinfection device body and the automated dense sampling system are used in conjunction with each other. The automated dense sampling system is used to detect and inspect the near-field irradiance of the disinfection device body.

[0048] Through the above technical solution: the dense sampling system of the present invention is used as a supporting facility for the ultraviolet disinfection device. After the ultraviolet disinfection device has been used for a certain period, the dense sampling system is used to detect the ultraviolet light in the near-field area of ​​the disinfection device, and the detected irradiance value is compared with the irradiance value calculated by the model to judge the attenuation level of the ultraviolet lamp of the disinfection device. After the attenuation of the ultraviolet lamp of the disinfection device is determined, the calculated attenuation degree is used as the basis for adjusting the parameters of the disinfection device or improving the product.

[0049] In summary, the present invention has the following beneficial effects:

[0050] (1) The existing technology for near-field irradiance detection technology does not mention the dense sampling detection idea. Usually, when the existing technology uses the dense sampling detection idea to detect the irradiance in the near-field area of ​​the ultraviolet lamp, the irradiance of each detection point needs to be measured by a radiometer. The number of radiometers required is very large, and the cost is even greater. The dense sampling detection idea is almost impossible to implement in practice. In another case, if the existing technology uses the method of detecting a very large number of irradiance detection points one by one, the detection efficiency is very low due to the lack of automated design, and the practical implementation is also almost impossible.

[0051] Therefore, the present invention achieves automated and efficient detection sampling through a dense sampling method during the operation of an automated dense sampling system. Compared to traditional dense sampling techniques that require the installation of a radiometer at each detection point, the dense sampling method and system of the present invention can significantly reduce the number of radiometers used. Furthermore, the dense sampling method during the operation of the automated dense sampling system provides a sampling efficiency that is acceptable to practical performance. Thus, the present invention strikes a reasonable balance between sampling efficiency and system cost, ultimately achieving more accurate irradiance value detection that is realistic and achievable.

[0052] (2) After providing a more accurate near-field irradiance distribution through the present invention, a mathematical model can be further established based on the near-field irradiance distribution, that is, the near-field irradiance distribution can be simulated and expressed in the form of a mathematical formula (mathematical model).

[0053] (3) After the establishment of the mathematical model of the near-field irradiance distribution by the dense sampling method and system of the present application, the model can be applied to the disinfection device, so that the disinfection device can know the irradiance distribution (irradiance value) in the near-field region around itself through model calculation, thereby providing an important tool for the research of the irradiation dose of the ultraviolet disinfection device and the improvement of the product.

[0054] (4) As a supporting facility of the ultraviolet disinfection device (disinfection robot), the dense sampling system of the present application can detect the ultraviolet light in the near-field region of the disinfection robot after the disinfection robot is used for a certain period of time, compare the detected irradiance value with the irradiance value calculated by the model, judge the attenuation level of the ultraviolet lamp tube of the disinfection robot, and after determining the attenuation of the ultraviolet lamp tube of the disinfection robot, use the calculated attenuation degree as the basis for parameter adjustment or product improvement of the disinfection robot.

[0055] Parameter adjustment, for example:

[0056] ① Adjust the initial irradiance value of the irradiance distribution model to obtain more accurate near-field irradiance value after attenuation;

[0057] ② Adjust the walking path of the disinfection robot, the distance between the disinfection robot and the disinfected object, and reasonably control the irradiation dose;

[0058] ③ Adjust the walking speed of the disinfection robot, slow down the walking speed of the disinfection robot, prolong the disinfection time, and reasonably control the irradiation dose.

[0059] Product improvement, for example:

[0060] ① Replace the ultraviolet lamp tube of the disinfection robot to ensure that the model calculation result and the actual near-field irradiance distribution are basically the same. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0069] Below with reference to the embodiment and the attached Figures 1-7 The present invention will be described in further detail, but the embodiments of the present invention are not limited thereto.

[0070] The irradiance sampling method of the present invention aims to achieve efficient, automated, dense sampling. Dense sampling means sampling at 7.2° intervals within the UV lamp angle range θ∈[0,300°], at 4.75cm intervals within the distance range d∈[50cm,202cm], and at 6.3cm intervals within the height range h∈[-18.9cm,163.8cm]. A total of 41,580 sampling points are used. This is referred to as dense sampling of UV lamp irradiance in the present invention.

[0071] Of course, the dense sampling is not absolutely refer to the total of 41580 sampling points, when the direction angle θ of the UV tube changes, the length d changes, the height h changes, or the interval sampling interval parameter changes among the three, the total number of sampling points of the dense sampling changes, when the total number of sampling points in the specified sampling area is higher than the set standard, it can be called dense sampling.

[0072] In the present application, how to realize efficient automation and low-cost dense sampling is the research focus, and the significance of the dense sampling result lies in the fact that it can provide more accurate UV tube near-field irradiance distribution analysis, and further provide effective data basis for subsequent near-field irradiance modeling.

[0073] After the near-field irradiance modeling of the UV tube is completed according to the dense sampling result, the near-field irradiance of the UV tube can be calculated through the model (advanced mathematical formula); when the model is applied to the UV disinfection device, the disinfection device can calculate the irradiance value at a specific distance, height and incident angle near it by using the model, and then combined with the national standard of the disinfection industry for the requirement of irradiation dose, the reasonable disinfection working time of the disinfection device can be more accurately calculated and controlled, and the disinfection effect can be optimized.

[0074] As to how to realize efficient automation and low-cost dense sampling, first of all, the present embodiment discloses the following one kind of automatic dense sampling method, the overall working principle of the dense sampling method includes two parts: preparation work and sampling work, which are as follows.

[0075] Preparation work: selecting a tubular ultraviolet light radiation source to be sampled, and selecting n ultraviolet light irradiance measuring instruments, which are arranged in the two-dimensional plane where the center line of the tubular ultraviolet light radiation source is located. The reason why the n ultraviolet light irradiance measuring instruments are arranged in the two-dimensional plane where the center line of the tubular ultraviolet light radiation source is located is that the rotation of this two-dimensional plane around the center line of the tubular ultraviolet light radiation source by 360° is the three-dimensional space region around the tubular ultraviolet light radiation source, thereby facilitating the dense sampling of the three-dimensional space region around the tubular ultraviolet light radiation source.

[0076] Sampling work: starting the measurement work of the preset measurement region in the first plane where the n ultraviolet light irradiance measuring instruments are currently located, that is, performing irradiance detection on the preset measurement region of the first plane. The detection method is: controlling the n ultraviolet light irradiance measuring instruments to scan each irradiance collection point in the preset measurement region of the first plane to obtain the irradiance value of each irradiance collection point. The meaning of scanning here is that the n ultraviolet light irradiance measuring instruments scan the preset measurement region along the preset direction, and the scanning process is to stop detection after moving a certain distance, and then stop detection again after moving a certain distance, and ensure that all sampling points in the preset measurement region are measured by the instruments.

[0077] Control the plane where the n ultraviolet irradiance measuring instruments are located to rotate a first preset angle compared to the first plane mentioned above, and take the center line of the tubular ultraviolet radiation source as the axis during the rotation process, as a second plane.

[0078] Start the measurement work of the preset measurement area in the second plane where the n ultraviolet irradiance measuring instruments are currently located, that is, perform irradiance detection on the preset measurement area of the first plane. The detection method is to control the n ultraviolet irradiance measuring instruments to scan each irradiance collection point in the preset measurement area in the second plane to obtain the irradiance value of each irradiance collection point at present.

[0079] Control the plane where the n ultraviolet irradiance measuring instruments are located to continue rotating a first preset angle compared to the second plane mentioned above, and take the center line of the tubular ultraviolet radiation source as the axis during the rotation process, as a third plane.

[0080] Accordingly, the n ultraviolet irradiance measuring instruments are controlled in turn to scan each irradiance collection point in the preset measurement area in the third plane to... the mth plane, so as to finally obtain the irradiance value of each irradiance collection point in the second preset angle in the near-field region of the tubular ultraviolet radiation source.

[0081] In addition to the above-mentioned three-dimensional space area detection scheme realized by rotating a two-dimensional plane around the center line of the tubular ultraviolet radiation source by 360°, the present embodiment also has a second approach.

[0082] Preparation work: select a tubular ultraviolet radiation source to be sampled, and select n ultraviolet irradiance measuring instruments and arrange them in a cylindrical surface with the center line of the tubular ultraviolet radiation source as the axis;

[0083] Sampling work: start the measurement work of the preset measurement area in the first cylindrical surface where the n ultraviolet irradiance measuring instruments are currently located, that is, perform irradiance detection on the preset measurement area of the first cylindrical surface. The detection method is to control the n ultraviolet irradiance measuring instruments to scan each irradiance collection point in the preset measurement area in the first cylindrical surface to obtain the irradiance value of each irradiance collection point at present. The meaning of scanning here is that the n ultraviolet irradiance measuring instruments rotate around the center line of the tubular ultraviolet radiation source as the axis, and the rotation process is to rotate by a certain angle and then stop for detection, continue to rotate by a certain angle and then stop for detection, until each irradiance collection point in the preset measurement area of the first cylindrical surface is measured by the instrument.

[0084] Control the cylindrical surface where the n ultraviolet irradiance measuring instruments are located to change the first preset radius compared to the first cylindrical surface mentioned above, that is, increase or decrease the first preset radius, as a second cylindrical surface.

[0085] Initiate measurement of a preset measurement area within the second cylindrical surface where the n ultraviolet irradiance measuring instruments are currently located, i.e., perform irradiance detection on the preset measurement area of ​​the second cylindrical surface. The detection method is to control the n ultraviolet irradiance measuring instruments to scan each irradiance collection point within the preset measurement area within the second cylindrical surface to obtain the irradiance value of each current irradiance collection point.

[0086] The cylindrical surface on which n ultraviolet irradiance measuring instruments are located is controlled to continue changing by a first preset radius compared to the second cylindrical surface, thereby forming a third cylindrical surface. Finally, the n ultraviolet irradiance measuring instruments are sequentially controlled to scan the third cylindrical surface to each irradiance collection point in a preset measurement area within the mth cylindrical surface, thereby ultimately obtaining an irradiance value at each irradiance collection point within a preset angle within the near-field region of the tubular ultraviolet radiation source.

[0087] The following describes the dense sampling method in detail through specific embodiments, taking the first approach as an example.

[0088] Select a UV lamp or multiple UV lamps arranged parallel to each other as the tubular UV radiation source, that is, as the detection object of the UV near-field irradiance distribution. The UV irradiance measuring instrument is a homemade or purchased UV radiometer, and the number is selected to be 30. The 30 radiometers are arranged in a two-dimensional plane where the center line of the UV lamp is located, and the 30 radiometers are arranged in a straight line in the two-dimensional plane. The straight line arrangement can be arranged vertically, horizontally, or in other inclined directions. The scanning direction of the 30 radiometers is perpendicular to the line connecting the radiometers in the straight line.

[0089] Scenario 1: When 30 radiometers are arranged vertically in a two-dimensional plane and controlled to scan horizontally, a rectangular area can be scanned. The total length of the line connecting the 30 radiometers and the scanning distance in the horizontal direction are preset to form a preset measurement area.

[0090] Scenario 2: When 30 radiometers are arranged horizontally in a two-dimensional plane and controlled to scan vertically, a rectangular area can be scanned. The total length of the line connecting the 30 radiometers and the scanning height in the vertical direction are preset to form a preset measurement area.

[0091] Taking case one as an example: 30 irradiance meters are arranged in a vertical direction in a two-dimensional plane, and the irradiance meters are arranged at intervals of 6.3 cm in the vertical direction, the bottom end of the ultraviolet lamp tube is defined as the origin in the three-dimensional coordinates (when there are multiple parallel ultraviolet lamp tubes, the bottom end of the center line of the ultraviolet lamp tube is defined as the origin), the lowest end of the 30 irradiance meters is set to -18.9 cm, and the highest end of the 30 irradiance meters is 163.8 cm. And the closest scanning point of the 30 irradiance meters in the horizontal direction is 50 cm, and the farthest scanning point is 202 cm, and sampling is performed at intervals of 4.75 cm between the closest scanning point and the farthest scanning point.

[0092] Therefore, in this parameter setting case, the length of the preset measurement region is in the distance range d e [50 cm, 202 cm]. The height of the preset measurement region is in the height range h e [-18.9 cm, 163.8 cm]. Each irradiance collection point in the preset measurement region in the two-dimensional plane is spaced apart by 6.3 cm in the height direction and spaced apart by 4.75 cm in the length direction. It can be seen that the total length of the rectangular preset measurement region is 152 cm, there are 32 measurement intervals, and there are 33 sampling points. The total height is 182.7 cm, there are 29 measurement intervals, and there are 30 sampling points. Therefore, there are a total of (30*33=990) sampling points in the rectangular preset measurement region.

[0093] Meanwhile, in the three-dimensional space, the first preset angle is 7.2°, and the second preset angle is 300°. There are 41 angle intervals and 42 sampling two-dimensional planes. Therefore, the total number of sampling points of the dense sampling method in the embodiment is (990*42=41580).

[0094] In addition, the tubular ultraviolet light radiation source can be configured as an ultraviolet light lamp tube. The tubular ultraviolet light radiation source can also be configured as a disinfection robot provided with an ultraviolet light lamp tube.

[0095] In summary, the dense sampling method of the present application sequentially collects irradiance data in the preset sampling region in the two-dimensional plane in the three-dimensional coordinate space, with a total of (41580) sampling points, high detection sampling efficiency, and low cost.

[0096] Based on the above dense sampling method, the present application further discloses a dense sampling system capable of automatically and efficiently implementing the dense sampling method, which comprises a tubular ultraviolet light radiation source, n ultraviolet light irradiance measuring instruments, a scanning controller, a rotation controller, and a data server. The n ultraviolet light irradiance measuring instruments are in communication connection with the data server; and the data server is used for receiving the irradiance values measured by the n ultraviolet light irradiance measuring instruments.

[0097] In the first dense sampling method idea described above, the connection structure of the dense sampling system corresponding to the operation idea is as follows:

[0098] N ultraviolet irradiance measuring instruments are located in a two-dimensional plane where the center line of the tubular ultraviolet radiation source is located.

[0099] The scanning controller is connected to n ultraviolet irradiance measuring instruments or tubular ultraviolet radiation sources. The scanning controller is used to jointly control the n ultraviolet irradiance measuring instruments to scan each irradiance collection point of a preset measurement area in a two-dimensional plane to obtain the irradiance value of each irradiance collection point in the two-dimensional plane.

[0100] The rotation controller is connected to n ultraviolet irradiance measuring instruments or tubular ultraviolet radiation sources. The rotation controller is used to control the two-dimensional plane where the current position of the n ultraviolet irradiance measuring instruments is located to rotate by a first preset angle compared to the two-dimensional plane where the previous position is located. The rotation process uses the center line of the tubular ultraviolet radiation source as the axis.

[0101] Therefore, through the above structural setting, the joint control of the scanning controller and the rotation controller can realize the detection of irradiance values ​​at each irradiance collection point in the preset measurement area in all two-dimensional planes in the three-dimensional space around the tubular ultraviolet radiation source.

[0102] Similar to the dense sampling method, the dense sampling system also selects a single UV lamp or multiple parallel UV lamps as the tubular UV radiation source, i.e., as the detection target of the UV near-field irradiance distribution. The UV irradiance measuring instrument is a self-made or purchased UV radiometer, and the number is selected to be 30. The 30 radiometers are arranged in a two-dimensional plane located on the centerline of the UV lamp, and the 30 radiometers are arranged in a straight line in the two-dimensional plane. The straight line arrangement can be arranged vertically, horizontally, or in other inclined directions. The scanning direction of the 30 radiometers is perpendicular to the line connecting the radiometers in the straight line.

[0103] Scenario 1: When 30 radiometers are arranged vertically in a two-dimensional plane and controlled to scan horizontally, a rectangular area can be scanned. The total length of the line connecting the 30 radiometers and the scanning distance in the horizontal direction are preset to form a preset measurement area.

[0104] Scenario 2: When 30 radiometers are arranged horizontally in a two-dimensional plane and controlled to scan vertically, a rectangular area can be scanned. The total length of the line connecting the 30 radiometers and the scanning height in the vertical direction are preset to form a preset measurement area.

[0105] Taking case one as an example: 30 irradiance meters are arranged in a two-dimensional plane along the vertical direction, and are arranged at intervals of 6.3 cm along the vertical direction. In the three-dimensional coordinate, the bottom end of the ultraviolet lamp tube is defined as the origin (when there are multiple parallel ultraviolet lamp tubes, the bottom end of the center line of the ultraviolet lamp tube is defined as the origin), the lowest end of the 30 irradiance meters is set to -18.9 cm, and the highest end of the 30 irradiance meters is 163.8 cm. The closest point of the scanning along the horizontal direction is 50 cm, and the farthest point of the scanning is 202 cm, and sampling is performed at intervals of 4.75 cm between the closest point and the farthest point.

[0106] Therefore, in this parameter setting case, the length d of the preset measurement region is in the distance range [50 cm, 202 cm]. The height h of the preset measurement region is in the height range [-18.9 cm, 163.8 cm]. Each irradiance collection point in the preset measurement region in the two-dimensional plane is spaced apart by 6.3 cm in the height direction and spaced apart by 4.75 cm in the length direction. It can be seen that the total length of the rectangular preset measurement region is 152 cm, there are 32 measurement intervals, and there are 33 sampling points. The total height is 182.7 cm, there are 29 measurement intervals, and there are 30 sampling points. Therefore, there are a total of (990) sampling points in the rectangular preset measurement region.

[0107] Meanwhile, in the three-dimensional coordinate, the first preset angle is 7.2°, and the second preset angle is 300°. There are 41 angle intervals and 42 sampling two-dimensional planes. Therefore, the total number of sampling points of the dense sampling method in this embodiment is (41580) sampling points.

[0108] In addition, the tubular ultraviolet light radiation source can be configured as an ultraviolet light lamp tube. The tubular ultraviolet light radiation source can also be configured as a disinfection robot provided with an ultraviolet light lamp tube.

[0109] To realize the function of the scanning controller, that is, to realize the control of the 30 irradiance meters to complete the detection of all the sampling points of the preset sampling region in the two-dimensional plane, the specific structure of the scanning controller can include three structure forms, as follows:

[0110] The first structure form of the scanning controller: the scanning controller includes a mounting carrier, a slide rail, and a first driving member. The 30 irradiance meters are fixed along a straight line on the mounting carrier, the mounting carrier is slidingly installed on the slide rail, and the first driving member controls the mounting carrier to slide on the slide rail. The mounting carrier drives the 30 irradiance meters to slide on the slide rail, thereby realizing the scanning process of the preset measurement region.

[0111] The second structure of the scanning controller: the scanning controller also includes a mounting carrier, a slide rail and a first driving member, and the ultraviolet lamp tube is fixed on the mounting carrier, the mounting carrier is slidingly installed on the slide rail, and the first driving member controls the mounting carrier to slide on the slide rail; the mounting carrier drives the ultraviolet lamp tube to slide on the slide rail (equivalent to the mounting carrier driving 30 irradiance meters to slide on the slide rail), and the scanning process of the preset measurement area is realized.

[0112] The third structure of the scanning controller: two groups of scanning controllers are provided, and the two groups of scanning controllers each include a mounting carrier, a slide rail and a first driving member; in the structure of one group of scanning controllers, 30 irradiance meters are fixed on the mounting carrier along a straight line, the mounting carrier is slidingly installed on the slide rail, and the first driving member controls the mounting carrier to slide on the slide rail; in the structure of the other group of scanning controllers, the ultraviolet lamp tube is fixed on the mounting carrier, the mounting carrier is slidingly installed on the slide rail, and the first driving member controls the mounting carrier to slide on the slide rail; and the sliding directions of the 30 irradiance meters and the ultraviolet lamp tube are located on the same straight line, so that the 30 irradiance meters and the ultraviolet lamp tube slide towards each other or away from each other under the driving action of the two first driving members.

[0113] Among them, in the structure installation direction, when the ultraviolet lamp tube is arranged in the vertical direction, the mounting carrier is arranged in the vertical direction, the slide rail is arranged in the horizontal direction, and the scanning direction is to scan in the horizontal direction. When the ultraviolet lamp tube is arranged in the vertical direction, the mounting carrier is arranged in the horizontal direction, the slide rail is arranged in the vertical direction, and the scanning direction is to scan in the vertical direction.

[0114] To realize the function of the rotating controller, that is, to realize the rotation of the two-dimensional plane where the current position of the 30 irradiance meters is located by a first preset angle compared with the two-dimensional plane where the previous position is located, the specific structure of the rotating controller can include a rotating disc and a second driving member, the second driving member controls the rotating disc to rotate, and the rotating disc drives the ultraviolet lamp tube to rotate or drives the 30 irradiance meters to rotate around the ultraviolet lamp tube, both of which can realize the rotation of the detection plane by a first preset angle.

[0115] Among them, the first driving member and the second driving member can be selected to be a stepper motor.

[0116] According to the above system structure, the embodiment further gives a specific implementation scheme of the automatic dense sampling system below. Referring to the drawings, the bottom end of the tubular ultraviolet light radiation source is defined as the origin (the center line of the ultraviolet lamp tube or the center line of the disinfection robot is taken as the origin when there are multiple parallel ultraviolet lamp tubes or when it is a disinfection robot):

[0117] The tubular ultraviolet light radiation source 1 is configured as a disinfection robot with ultraviolet lamp tubes (not shown in the figure);

[0118] The n ultraviolet light irradiance measuring instruments 2 are configured as 30 irradiance meters;

[0119] The scanning controller 3 is configured to be a mounting carrier 3-1, a slide rail 3-2 and a first driving member 3-3. 30 irradiance meters are fixed on the front surface of the mounting carrier 3-1 at equal intervals in the vertical direction, with a total of 30 sampling points in the height direction. The height range of the irradiance meters is h∈[-18.9cm,163.8cm] in the height direction, and the irradiance meters are installed at intervals of 6.3cm in the height direction. The bottom end of the mounting carrier 3-1 is slidably connected to the slide rail 3-2, and the first driving member 3-3 is configured as a motor to drive the bottom end of the mounting carrier 3-1 to slide on the slide rail 3-2.

[0120] A support rod 3-4 is also provided on the side of the mounting member 3-1 facing away from the radiometer. This rod is used to maintain the stability of the mounting member 3-1 during its sliding motion and to reduce the positional error between the actual sampling point and the theoretical sampling point. To enable the mounting member 3-1 to slide on the surface of the slide rail 3-2, a sliding connection block 3-5 is fixed to the bottom end of the mounting member 3-1. A belt 3-21 is provided within the slide rail 3-2. A first drive member 3-3 drives the belt 3-21. The sliding connection block 3-5 is fixed to the belt 3-21, and the movement of the belt 3-21 causes the sliding connection block 3-5 to slide synchronously.

[0121] In this embodiment, the first driving member 3-3 drives the mounting member 3-1 to slide a single distance of 4.75 cm, and slides within a distance range of length d∈[50 cm, 202 cm], thereby sliding 32 times at intervals of 4.75 cm within the distance range, with a total of 33 sampling points in the horizontal direction.

[0122] The rotation controller 4 is configured as a turntable 4-1 and a second drive member 4-2. The disinfection robot is fixed on the upper surface of the turntable 4-1 (not shown in the figure). The second drive member 4-2 drives the turntable 4-1 to rotate a first preset angle. In this embodiment, the first preset angle is 7.2°, and the second drive member 4-2 is used to drive the turntable 4-1 to rotate 41 angle intervals within the range of 300° of the second preset angle, that is, rotate 41 times, and a total of 42 sampling two-dimensional planes in the three-dimensional space.

[0123] The 30 radiometers are communicatively connected to a data server 5, which is used to receive the irradiance values ​​measured by the 30 radiometers and store and perform modeling processing. Modeling processing refers to establishing a mathematical formula using the measured irradiance values, so that the near-field irradiance can be calculated based on distance variables, height variables, and incident angle variables.

[0124] When the model is applied to a UV disinfection device, the disinfection device can use the model to calculate the irradiance value at a specific distance, height and incident angle near it. Combined with the national standards for irradiation dose in the disinfection industry, the reasonable disinfection working time of the disinfection device can be calculated and controlled more accurately, thereby optimizing the disinfection effect.

[0125] In the second dense sampling method mentioned above, the connection structure of the dense sampling system corresponding to this operation idea is as follows:

[0126] n ultraviolet irradiance measuring instruments are located in a cylindrical surface with the center line of the tubular ultraviolet radiation source as the axis;

[0127] The rotary controller is connected to n ultraviolet irradiance measuring instruments or tubular ultraviolet radiation sources, and the rotary controller is used to control the n ultraviolet irradiance measuring instruments to scan each irradiance collection point of a preset measurement area within the cylindrical surface to obtain the irradiance value of each current irradiance collection point;

[0128] The scanning controller is connected to n ultraviolet irradiance measuring instruments or tubular ultraviolet radiation sources, and is used to control the radius of the cylindrical surface at the current position of the n ultraviolet irradiance measuring instruments to increase or decrease the first preset radius compared with the radius of the cylindrical surface at the previous position.

[0129] Under this connection structure, as shown in the figure, at this time, the bottom end of the mounting carrier 3-1 is slidably connected to the slide rail 3-2, and the single sliding distance is 4.75 cm, and it slides within a distance range of length d∈[50 cm, 202 cm], thereby sliding 32 times at intervals of 4.75 cm within the distance range, with a total of 33 sampling points in the horizontal direction.

[0130] When the mounting carrier 3-1 is at a certain sampling point, the second driving member 4-2 is used to drive the turntable 4-1 to rotate 41 angle intervals within the second preset angle range of 300°, each angle interval is 7.2° of the first preset angle, that is, it rotates 41 times, totaling 42 sampling buses.

[0131] Therefore, one radiometer can collect a total of (33*42=1386) sampling points. If 30 radiometers are installed on the mounting carrier 3-1, a total of (1386*30=41580) sampling points can be collected.

[0132] In addition, an embodiment of the present invention further discloses an ultraviolet disinfection device using an automated dense sampling system. The automated dense sampling system and the ultraviolet disinfection device are used in conjunction to regularly detect and inspect the near-field irradiance distribution of the disinfection device.

[0133] The advantage of using them in combination is that the near-field irradiance calculated by the model is the first value, and the near-field irradiance actually measured by the automated dense sampling system is the second value. The error between the first value and the second value is compared, and the attenuation level of the ultraviolet lamp is judged by the error. When the ultraviolet lamp is not replaced with a new one, the model can be adjusted according to the error value to allow the model to calculate the accurate irradiance value after attenuation, and then the disinfection time is calculated according to the calculated irradiance value, thereby obtaining a reasonable travel speed of the disinfection robot, or a reasonable walking path of the disinfection robot, to achieve reasonable control of the irradiation dose.

[0134] Therefore, when the automated dense sampling system and the ultraviolet disinfection device (disinfection robot) are used in conjunction with each other, a matching product is formed, which can continuously (or so-called "regularly") effectively guarantee the disinfection effect of the ultraviolet disinfection device, which has not been mentioned in the prior art.

[0135] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the principles of the present invention are within the scope of protection of the present invention. It should be noted that improvements and modifications that do not depart from the principles of the present invention are within the scope of protection of the present invention.
