Description

Technical Field

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

[0002] In recent years, many studies have shown that ultraviolet disinfection is superior to manual disinfection in terms of disinfection effect and efficiency. In the field of ultraviolet disinfection technology, according to theoretical definition, the irradiation dose is the cumulative integral value of irradiance over time. The ultraviolet irradiation dose is the key parameter affecting the disinfection effect. Therefore, accurate calculation and reasonable control of the irradiation dose is the core technology to achieve efficient disinfection of the disinfection device.

[0003] In the prior art, the detection scheme of near-field irradiance distribution has the following problems: on the one hand, the detection cost is high; on the other hand, the detection efficiency is low. At present, no efficient and low-cost dense measurement scheme has been proposed, which makes it difficult to perform fast and dense irradiance distribution sampling around the disinfection device, so that sufficient sampling data cannot be obtained, and it is difficult to compare the calculated value of the disinfection device with the actual sampling value efficiently and at low cost. This limitation restricts the research on the irradiation dose of the disinfection device and product improvement.

[0004] The high detection cost in the prior art is mainly reflected in the fact that when performing point-to-point irradiance measurement in the near-field area of ​​the UV lamp, a radiometer needs to be installed at each detection point. This means that the number of radiometers required is very large, and the cost of a single radiometer is relatively high, resulting in a significant increase in the overall detection cost. In addition, the low detection efficiency in the prior art means that if the radiometer is used to measure the detection points 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 relatively low 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 relatively low-cost and efficient manner, which was originally difficult to achieve in the prior art.

[0006] In order to solve the above technical problems, the present invention first provides the following technical solution 1: An automated dense sampling method comprises the following steps: S1. Preparation: 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; S2. Sampling work: Start measuring the preset measurement area in the first plane where n UV irradiance measuring instruments are currently located: S2-1, controlling n ultraviolet irradiance measuring instruments to scan each irradiance collection point in a preset measurement area in the first plane to obtain the irradiance value of each current irradiance collection point; 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 as the second plane during the rotation process; Start the measurement work of the preset measurement area in the second plane where n UV irradiance measuring instruments are currently located: S2-2, controlling 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 current irradiance collection point; Controlling the plane where the n ultraviolet irradiance measuring instruments are located to continue rotating by a first preset angle compared to the second plane, with the center line of the tubular ultraviolet radiation source as the axis during the rotation process, as the third plane; Finally, n ultraviolet irradiance measuring instruments are sequentially controlled to scan each irradiance collection point of the preset measurement area from the third plane to the m-th plane, so as to finally obtain the irradiance value of each irradiance collection point within the second preset angle in the near field area of ​​the tubular ultraviolet radiation source; or, An automated dense sampling method comprises the following steps: S1', Preparation: 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; S2', sampling work: Start measuring the preset measurement area within the first cylindrical surface where the n UV irradiance measuring instruments are currently located: S2-1', controlling n ultraviolet irradiance measuring instruments to scan each irradiance collection point in a preset measurement area within the first cylindrical surface to obtain the irradiance value of each current irradiance collection point; Controlling the cylindrical surface where n ultraviolet irradiance measuring instruments are located to change by a first preset radius compared with the first cylindrical surface to serve as the second cylindrical surface; Start the measurement work of the preset measurement area in the second cylindrical surface where the n ultraviolet irradiance measuring instruments are currently located: S2-2', controlling n ultraviolet irradiance measuring instruments to scan each irradiance collection point in the preset measurement area within the second cylindrical surface to obtain the irradiance value of each current irradiance collection point; Controlling the cylindrical surface where the n ultraviolet irradiance measuring instruments are located to continue changing the first preset radius compared with the second cylindrical surface to serve as the third cylindrical surface; Finally, n ultraviolet irradiance measuring instruments are controlled in sequence to scan each irradiance collection point in the preset measurement area from the third cylindrical surface to the mth cylindrical surface, so as to finally obtain the irradiance value of each irradiance collection point within the preset angle in the near-field area of ​​the tubular ultraviolet radiation source.

[0007] Through the above technical solution: the basic working principle of the automated dense sampling method of the present invention is to control n ultraviolet radiometers to efficiently and automatically scan each collection point in the near-field area to obtain the irradiance value of each collection point, thereby providing a more accurate irradiance distribution in the near-field area.

[0008] There are two main ideas for the scanning process. The first idea is: use n linearly distributed UV irradiance meters to scan all the collection points in the preset measurement area in the first two-dimensional plane along the direction perpendicular to the line connecting them, so as to realize the detection of all the collection points in the preset measurement area in the first two-dimensional plane; then control the first two-dimensional plane to rotate by a preset angle to form a second two-dimensional plane...the mth plane, and realize the detection of all the collection points in the near field area in this cycle.

[0009] The second idea is: use n ultraviolet irradiance meters arranged in the cylindrical surface to rotate and scan all the collection points in the first cylindrical surface to realize the detection of all the collection points in the preset measurement area in the first cylindrical surface; then control the n ultraviolet 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, so as to realize the detection of all the collection points in the near field area in this cycle.

[0010] The present invention also provides the following technical solution 2: An automated dense sampling system, comprising: a tubular ultraviolet radiation source, n ultraviolet irradiance measuring instruments, a scanning controller, a rotation controller and a data server; n ultraviolet light irradiance measuring instruments are connected to a data server for communication; the data server is used to receive irradiance values ​​measured by the n ultraviolet light irradiance measuring instruments; n ultraviolet irradiance measuring instruments are located in a two-dimensional plane where the center line of the tubular ultraviolet radiation source is located; 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 the irradiance value of each irradiance collection point in the two-dimensional plane; The rotation controller is connected to n ultraviolet irradiance measuring instruments or tubular ultraviolet radiation sources, and 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 with the two-dimensional plane where the previous position is located, and the rotation process uses the center line of the tubular ultraviolet radiation source as the axis; or, An automated dense sampling system, comprising: a tubular ultraviolet radiation source, n ultraviolet irradiance measuring instruments, a scanning controller, a rotation controller and a data server; n ultraviolet light irradiance measuring instruments are connected to a data server for communication; the data server is used to receive irradiance values ​​measured by the n ultraviolet light irradiance measuring instruments; n ultraviolet irradiance measuring instruments are located in a cylindrical surface with the center line of the tubular ultraviolet radiation source as the axis; 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; 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 where the n ultraviolet irradiance measuring instruments are currently located to increase or decrease the radius by a first preset radius compared to the radius of the cylindrical surface where the previous position is located.

[0011] 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.

[0012] The present invention further provides the following technical solution three: The ultraviolet disinfection device comprises 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.

[0013] Through the above technical scheme: the dense sampling system of the present invention is used as a supporting facility for the ultraviolet disinfection device. After the ultraviolet disinfection device is used for a certain period of time, 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.

[0014] In summary, the present invention has the following beneficial effects: (1) The existing technology does not mention the dense sampling detection idea in the near-field irradiance detection technology. Usually, when the existing technology uses the dense sampling detection idea to detect the irradiance of the near-field area of ​​the ultraviolet lamp, the irradiance of each detection point needs to be measured by a radiometer, so the number of radiometers required is very large, and the cost is very large, and the dense sampling detection idea is almost impossible to achieve in reality. In another case, if the existing technology uses a very large number of irradiance detection points to detect one by one, due to the lack of automated design, the detection efficiency is very low, and the realistic realization is also almost impossible.

[0015] Therefore, the present invention realizes automated and efficient detection sampling through a dense sampling method when the automated dense sampling system is running. Compared with the traditional dense sampling technology that requires a radiometer to be installed at each detection point, the dense sampling method and system of the present invention can greatly reduce the number of radiometers used, and use the dense sampling method when the automated dense sampling system is running to provide a sampling efficiency that is acceptable to the actual performance, so that the present invention makes a reasonable balance between sampling efficiency and system cost, and finally realizes more accurate irradiance value detection that is realistic and achievable.

[0016] (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 is simulated and expressed in the form of a mathematical formula (mathematical model).

[0017] (3) After the mathematical model of the near-field irradiance distribution is established by the dense sampling method and system of the present invention, when the model is applied to the disinfection device, the disinfection device can calculate the irradiance distribution (irradiance value) in the near-field area around itself through the model, thereby providing an important tool for the research on the irradiation dose of ultraviolet disinfection devices and product improvement.

[0018] (4) The dense sampling system of the present invention is used as a supporting facility for the ultraviolet disinfection device (disinfection robot). After the ultraviolet disinfection device has been used for a certain period of time, the dense sampling system is used to detect the ultraviolet light in the near-field area of ​​the disinfection robot. The detected irradiance value is compared with the irradiance value calculated by the model to determine the attenuation level of the ultraviolet lamp of the disinfection robot. After the attenuation of the ultraviolet lamp of the disinfection robot is determined, the calculated attenuation degree is used as the basis for adjusting the disinfection robot parameters or improving the product.

[0019] Parameter adjustments, such as: ① Adjust the initial irradiance value of the irradiance distribution model to obtain a more accurate near-field irradiance value after attenuation; ② Adjust the walking path of the disinfection robot, close the distance between the disinfection robot and the disinfected items, and reasonably control the radiation dose; ③ Adjust the walking speed of the disinfection robot, slow down the walking speed of the disinfection robot, extend the disinfection time, and reasonably control the radiation dose.

[0020] Product improvements such as: ① Replace the UV lamp of the disinfection robot to ensure that the calculation results of the near-field area model are basically the same as the actual near-field irradiance distribution. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] Below is a combination of the embodiments and the attached Figure 1-Figure 7 The present invention is further described in detail, but the embodiments of the present invention are not limited thereto.

[0024] The irradiance sampling method of the present invention aims to achieve efficient and automated dense sampling. Dense sampling means sampling at intervals of 7.2° in the range of the direction angle θ∈[0,300°] of the ultraviolet lamp, sampling at intervals of 4.75cm in the range of the distance of length d∈[50cm,202cm], and sampling at intervals of 6.3cm in the range of the height h∈[-18.9cm,163.8cm]. A total of (41580) sampling points. This is referred to as dense sampling of the irradiance of the ultraviolet lamp in the present invention.

[0025] Of course, dense sampling does not absolutely mean a total of (41580) sampling points. When the direction angle θ of the UV lamp changes, the length d changes, the height h changes, or the sampling interval parameters of the three change, the total number of sampling points of 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.

[0026] In the present invention, how to achieve efficient, automated and low-cost dense sampling is the research focus. The significance of the dense sampling results lies in being able to realistically provide a more accurate analysis of the near-field irradiance distribution of ultraviolet lamps, and further provide an effective data basis for subsequent near-field irradiance modeling.

[0027] After completing the modeling of the near-field irradiance of the UV lamp based on the dense sampling results, the near-field irradiance of the UV lamp can be calculated through the model (advanced mathematical formula); when the model is applied to the 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, and then combined with the national standards for the disinfection industry The requirements for irradiation dose can more accurately calculate and control the reasonable disinfection working time of the disinfection device and optimize the disinfection effect.

[0028] Regarding how to achieve efficient, automated and low-cost dense sampling, firstly, this embodiment discloses the following automated dense sampling method. The overall working principle of the dense sampling method includes two parts: preparation work and sampling work, which are detailed as follows.

[0029] Preparation: Select a tubular ultraviolet radiation source to be sampled, and select n ultraviolet irradiance measuring instruments, and arrange them in a two-dimensional plane where the center line of the tubular ultraviolet radiation source is located. The reason why the present invention arranges n ultraviolet irradiance measuring instruments in a two-dimensional plane where the center line of the tubular ultraviolet radiation source is located is that the two-dimensional plane rotates 360° around the center line of the tubular ultraviolet radiation source to form a three-dimensional space area around the tubular ultraviolet radiation source, thereby facilitating dense sampling of the three-dimensional space area around the tubular ultraviolet radiation source.

[0030] Sampling work: Start the measurement work of the preset measurement area in the first 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: control the n ultraviolet irradiance measuring instruments to scan each irradiance collection point in the preset measurement area in the first plane to obtain the irradiance value of each current irradiance collection point. The meaning of scanning here is that the n ultraviolet irradiance measuring instruments scan the preset measurement area along the preset direction. The scanning process is to stop for detection after moving a certain distance, continue to move a certain distance and then stop for detection, and ensure that all sampling points in the preset measurement area are measured by the instrument.

[0031] The plane where the n ultraviolet irradiance measuring instruments are located is controlled to rotate by a first preset angle compared to the aforementioned first plane, and the center line of the tubular ultraviolet radiation source is used as the axis during the rotation process as the second plane.

[0032] 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: control the n ultraviolet irradiance measuring instruments to scan each irradiance collection point of the preset measurement area in the second plane to obtain the irradiance value of each current irradiance collection point.

[0033] The plane where the n ultraviolet irradiance measuring instruments are located is controlled to continue to rotate by a first preset angle compared to the aforementioned second plane, and the rotation process uses the center line of the tubular ultraviolet radiation source as the axis, which serves as the third plane.

[0034] Accordingly, n ultraviolet irradiance measuring instruments are controlled in sequence to scan each irradiance collection point in the preset measurement area from the third plane to the mth plane, so as to finally obtain the irradiance value of each irradiance collection point within the second preset angle in the near-field area of ​​the tubular ultraviolet radiation source.

[0035] In addition to the above solution of realizing three-dimensional spatial area detection by rotating a two-dimensional plane 360° around the center line of the tubular ultraviolet radiation source, this embodiment also has a second idea.

[0036] Preparation: 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; 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: 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 current irradiance collection point. 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 stop for detection after rotating for a certain angle, and then stop for detection after continuing to rotate for a certain angle, until each irradiance collection point in the preset measurement area of ​​the first cylindrical surface is measured by the instrument.

[0037] The cylindrical surface where the n ultraviolet irradiance measuring instruments are located is controlled to change the first preset radius compared with the aforementioned first cylindrical surface, that is, to increase or decrease the first preset radius, to serve as the second cylindrical surface.

[0038] The measurement work of the preset measurement area in the second cylindrical surface where the n ultraviolet irradiance measuring instruments are currently located is started, that is, the irradiance detection is performed on the preset measurement area of ​​the second cylindrical surface. The detection method is: control the n ultraviolet irradiance measuring instruments to scan each irradiance collection point of the preset measurement area in the second cylindrical surface to obtain the irradiance value of each current irradiance collection point.

[0039] The cylindrical surface where the n ultraviolet irradiance measuring instruments are located is controlled to continue to change the first preset radius compared to the second cylindrical surface, as the 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 the preset measurement area within the m-th cylindrical surface, so as to finally obtain the irradiance value of each irradiance collection point within the preset angle in the near-field area of ​​the tubular ultraviolet radiation source.

[0040] The dense sampling method is described in detail below through specific embodiments, and the first idea is taken as an example.

[0041] Select a UV lamp or multiple UV lamps arranged in parallel with each other as a tubular UV radiation source, that is, as the detection object of UV near-field irradiance distribution. The UV irradiance measuring instrument is a self-made or purchased UV irradiance meter, and the number is selected to be 30. Arrange the 30 irradiance meters in a two-dimensional plane where the center line of the UV lamp is located, and arrange the 30 irradiance meters in a straight line in the two-dimensional plane. The direction of the straight line arrangement can be arranged in the vertical direction, or in the horizontal direction, or in other inclined directions. The scanning direction of the 30 irradiance meters is scanned in a direction perpendicular to the line connecting the irradiance meters arranged in a straight line.

[0042] Case 1: When 30 irradiance meters are arranged in a two-dimensional plane along the vertical direction and controlled to scan in the horizontal direction, a rectangular area can be scanned. The total length of the line connecting the 30 irradiance meters is preset, and the scanning distance in the horizontal direction is preset, thus forming a preset measurement area.

[0043] Scenario 2: When 30 irradiance meters 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 irradiance meters is preset, and the scanning height along the vertical direction is preset, thus forming a preset measurement area.

[0044] Take situation 1 as an example: 30 irradiometers are arranged vertically in a two-dimensional plane, and the irradiometers are set at 6.3 cm intervals in the vertical direction. The bottom of the UV lamp is defined as the origin in the three-dimensional coordinates (when there are multiple parallel UV lamps, the bottom of the center line of the UV lamp is the origin). The lowest end height of the 30 irradiometers is set to -18.9 cm, and the top height of the 30 irradiometers is 163.8 cm. In addition, the closest scanning point of the 30 irradiometers in the horizontal direction is 50 cm, and the farthest scanning point is 202 cm. Sampling is performed at intervals of 4.75 cm between the closest scanning point and the farthest scanning point.

[0045] Therefore, under this parameter setting, the preset measurement area has a length d∈[50cm,202cm] distance range. The preset measurement area has a height range h∈[-18.9cm,163.8cm]. Each irradiance collection point in the preset measurement area in the two-dimensional plane is spaced 6.3cm in the height direction and 4.75cm in the length direction. It can be seen that the total length of the rectangular preset measurement area is 152cm, with 32 measurement intervals, 33 sampling points, a total height of 182.7cm, 29 measurement intervals, and 30 sampling points. There are a total of (30*33=990) sampling points in the rectangular preset measurement area.

[0046] At the same time, in the three-dimensional space, the first preset angle is 7.2°, and the second preset angle is 300°, so there are 41 angle intervals and 42 sampling two-dimensional planes. Therefore, the total sampling points of the dense sampling method in this embodiment are (990*42=41580) sampling points.

[0047] In addition, the tubular ultraviolet radiation source can be configured as an ultraviolet lamp tube, or a disinfection robot equipped with an ultraviolet lamp tube.

[0048] In summary, the dense sampling method of the present invention sequentially collects irradiance data of preset sampling areas in a two-dimensional plane in a three-dimensional coordinate space, with up to (41580) collection points, and has high detection sampling efficiency and low cost.

[0049] Based on the above dense sampling method, the present invention also discloses a dense sampling system that can automatically and efficiently implement the dense sampling method. The dense sampling system includes five parts: a tubular ultraviolet radiation source, n ultraviolet irradiance measuring instruments, a scanning controller, a rotation controller and a data server. The n ultraviolet irradiance measuring instruments are communicatively connected to the data server; the data server is used to receive the irradiance values ​​measured by the n ultraviolet irradiance measuring instruments.

[0050] In the first dense sampling method mentioned above, the connection structure of the dense sampling system corresponding to this operation idea is as follows: The n ultraviolet irradiance measuring instruments are located in a two-dimensional plane where the center line of the tubular ultraviolet radiation source is located.

[0051] 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.

[0052] 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 positions of the n ultraviolet irradiance measuring instruments are located to rotate by a first preset angle compared to the two-dimensional plane where the previous positions are located. The rotation process uses the center line of the tubular ultraviolet radiation source as the axis.

[0053] 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.

[0054] The same as the dense sampling method, in the dense sampling system, a UV lamp or multiple UV lamps arranged in parallel are selected as tubular UV radiation sources, that is, as the detection object of UV near-field irradiance distribution. The UV irradiance measuring instrument is a self-made or purchased UV irradiance meter, and the number is selected to be 30. The 30 irradiance meters are arranged in a two-dimensional plane where the center line of the UV lamp is located, and the 30 irradiance meters are arranged in a straight line in the two-dimensional plane. The direction of the straight line arrangement can be arranged in the vertical direction, or in the horizontal direction, or in other inclined directions. The scanning direction of the 30 irradiance meters is scanned in a direction perpendicular to the line connecting the irradiance meters arranged in a straight line.

[0055] Case 1: When 30 irradiance meters are arranged in a two-dimensional plane along the vertical direction and controlled to scan in the horizontal direction, a rectangular area can be scanned. The total length of the line connecting the 30 irradiance meters is preset, and the scanning distance in the horizontal direction is preset, thus forming a preset measurement area.

[0056] Scenario 2: When 30 irradiance meters 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 irradiance meters is preset, and the scanning height along the vertical direction is preset, thus forming a preset measurement area.

[0057] Take situation 1 as an example: 30 irradiance meters are arranged vertically in a two-dimensional plane, and the irradiance meters are set at 6.3 cm intervals in the vertical direction. In the three-dimensional coordinates, the bottom of the UV lamp is defined as the origin (when there are multiple parallel UV lamps, the bottom of the center line of the UV lamp is the origin). The lowest end height of the 30 irradiance meters is set to -18.9 cm, and the top height of the 30 irradiance meters is 163.8 cm. In addition, the closest scanning point of the 30 irradiance meters in the horizontal direction is 50 cm, and the farthest scanning point is 202 cm. Sampling is performed at intervals of 4.75 cm between the closest scanning point and the farthest scanning point.

[0058] Therefore, under this parameter setting, the distance range of the preset measurement area length d∈[50cm,202cm]. The height range of the preset measurement area height h∈[-18.9cm,163.8cm]. Each irradiance collection point in the preset measurement area in the two-dimensional plane is spaced 6.3cm in the height direction and 4.75cm in the length direction. It can be seen that the total length of the rectangular preset measurement area is 152cm, with 32 measurement intervals, 33 sampling points, and a total height of 182.7cm, 29 measurement intervals, and 30 sampling points. There are a total of (990) sampling points in the rectangular preset measurement area.

[0059] At the same time, in the three-dimensional coordinates, the first preset angle is 7.2°, and the second preset angle is 300°, so there are 41 angle intervals and 42 sampling two-dimensional planes. Therefore, the total sampling points of the dense sampling method in this embodiment are (41580) sampling points.

[0060] In addition, the tubular ultraviolet radiation source can be configured as an ultraviolet lamp tube, or a disinfection robot equipped with an ultraviolet lamp tube.

[0061] In order to realize the function of the scanning controller, that is, to control 30 irradiance meters to complete the detection of all sampling points of the preset sampling area in the two-dimensional plane, the specific structure of the scanning controller can include three structural forms, as follows: The first structural form of the scanning controller: The scanning controller includes a mounting carrier, a slide rail and a first driving component. 30 irradiance meters are fixed on the mounting carrier along a straight line. The mounting carrier is slidably mounted on the slide rail. The first driving component controls the mounting carrier to slide on the slide rail. The mounting carrier drives the 30 irradiance meters to slide on the slide rail to realize the scanning process of the preset measurement area.

[0062] The second structural form of the scanning controller: The scanning controller also includes a mounting carrier, a slide rail and a first driving component, and the ultraviolet lamp is fixed on the mounting carrier, and the mounting carrier is slidably mounted on the slide rail. The first driving component controls the mounting carrier to slide on the slide rail, and the mounting carrier drives the ultraviolet lamp to slide on the slide rail (equivalent to the mounting carrier driving 30 irradiance meters to slide on the slide rail), thereby realizing the scanning process of the preset measurement area.

[0063] The third structural form of the scanning controller: two groups of scanning controllers are provided, and both groups of scanning controllers include a mounting carrier, a slide rail and a first driving member. In one group of the scanning controller structures, 30 irradiometers are fixed on the mounting carrier along a straight line, the mounting carrier is slidably mounted on the slide rail, and the first driving member controls the mounting carrier to slide on the slide rail; in the other group of the scanning controller structures, the ultraviolet lamp tube is fixed on the mounting carrier, the mounting carrier is slidably mounted 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 irradiometers and the ultraviolet lamp tube are on the same straight line, so that under the driving action of the two first driving members, the 30 irradiometers and the ultraviolet lamp tube slide towards each other or away from each other.

[0064] Wherein, in the structural installation direction, when the UV lamp 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 scanning in the horizontal direction. When the UV lamp 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 scanning in the vertical direction.

[0065] In order to realize the function of the rotation controller, that is, to control the two-dimensional plane where the current positions of the 30 irradiometers are located to rotate by a first preset angle compared to the two-dimensional plane where the previous positions are located, the specific structure of the rotation controller may include a turntable and a second driving member. The second driving member controls the rotation of the turntable, and the turntable drives the ultraviolet lamp to rotate on its own or drives the 30 irradiometers to revolve around the ultraviolet lamp at the same time. Both methods can realize the rotation of the detection plane by the first preset angle.

[0066] Wherein, both the first driving member and the second driving member can be configured as stepping motors.

[0067] According to the above system structure, this embodiment further provides a specific implementation plan for the automated dense sampling system. As shown in the figure, the bottom end of the tubular ultraviolet radiation source is defined as the origin (when there are multiple parallel ultraviolet lamps or a disinfection robot, the bottom end of the center line of the ultraviolet lamp or the center line of the disinfection robot is defined as the origin): The tubular ultraviolet radiation source 1 is configured as a disinfection robot with an ultraviolet lamp tube (not shown in the figure); n ultraviolet irradiance measuring instruments 2 are configured as 30 irradiance meters; The scanning controller 3 is configured to include 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. There are a total of 30 sampling points in the height direction. The mounting carrier 3-1 is installed in a height range of h∈[-18.9cm,163.8cm] in the height direction and 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. The first driving member 3-3 is configured to be driven by a motor to slide the bottom end of the mounting carrier 3-1 on the slide rail 3-2.

[0068] At the same time, a support rod 3-4 is provided on the side of the mounting member 3-1 away from the irradiometer, which is used to maintain the stability of the mounting member 3-1 during the sliding process and reduce the position error between the actual sampling point and the theoretical sampling point. In order to realize the sliding of the mounting member 3-1 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 in the slide rail 3-2, the first driving member 3-3 drives the belt 3-21 to move, and the sliding connection block 3-5 is fixed to the belt 3-21, and the sliding connection block 3-5 is driven to slide synchronously when the belt 3-21 moves.

[0069] 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∈[50cm,202cm], 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.

[0070] The rotation controller 4 is configured as a turntable 4-1 and a second driving member 4-2. The disinfection robot is fixed on the upper surface of the turntable 4-1 (not shown in the figure). The second driving member 4-2 drives the turntable 4-1 to rotate a first preset angle. In the present embodiment, the first preset angle is 7.2°, and the second driving 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 are sampled in the three-dimensional space.

[0071] 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. The 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.

[0072] 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 the disinfection industry on irradiation dose, it can more accurately calculate and control the reasonable disinfection working time of the disinfection device and optimize the disinfection effect.

[0073] In the second dense sampling method mentioned above, the connection structure of the dense sampling system corresponding to this operation idea is as follows: n ultraviolet irradiance measuring instruments are located in a cylindrical surface with the center line of the tubular ultraviolet radiation source as the axis; 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; 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 where the n ultraviolet irradiance measuring instruments are currently located to increase or decrease the radius by a first preset radius compared to the radius of the cylindrical surface where the previous position is located.

[0074] 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∈[50cm,202cm], 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.

[0075] 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.

[0076] Therefore, one radiometer can collect a total of (33*42=1386) sampling points. If 30 radiometers are installed on the mounting carrier 3-1, there are a total of (1386*30=41580) sampling points.

[0077] 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 combination to regularly detect and inspect the near-field irradiance distribution of the disinfection device.

[0078] 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 radiation dose.

[0079] 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 that can continuously (or "regularly") effectively guarantee the disinfection effect of the ultraviolet disinfection device, which has not been mentioned in the prior art.

[0080] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
