Description

Technical Field

[0001] This invention relates to the field of drug detection technology, and in particular to a rapid drug detection device capable of performing batch testing. Background Technology

[0002] Urine testing is a common and effective method of drug detection. Current drug research aims to screen for drugs by conducting urine tests on a certain population. However, there are some difficulties in both sampling and detection of drugs.

[0003] For example, from a sampling perspective, current technologies typically involve sampling within a specific target group or periodically screening relevant personnel in key locations. However, at the societal level, there isn't a particularly effective testing scope. From a testing perspective, while there are numerous drug test kits and strips available, and the time to obtain results is increasingly shorter, the sample run times vary when using test strips with colloidal gold methods. In batch testing, current technologies primarily rely on manual plate reading, or manual pre-judgment to determine if the plate has already run before machine reading. These tests still require manual operation and remain time-consuming and labor-intensive.

[0004] Furthermore, current technologies for bulk drug testing typically involve sampling and then taking the samples back for centralized testing. Even on-site testing requires a long wait for results, and this delay in feedback is highly detrimental to rapid response and handling after detection. For example, at temporary testing sites set up at airports, airport staff conduct on-site testing on individuals of high interest. After the on-site testing, due to the long result time, those tested, considering the public interest, may leave without waiting if they are not found to be positive. In this case, if the result is positive, it is necessary to track down the tested individual with the cooperation and coordination of other departments for a second test. However, if the interval between the second test is long, the test results may differ significantly, which is highly detrimental to the effective containment and screening of positive drug tests.

[0005] Existing technologies also offer some improvements to urine testing. For example, Chinese patent application CN106596910A discloses an automatic urine testing device, a toilet, and an automatic urine testing method. This belongs to a urine testing device with urine collection and disinfection functions for private, household, or small-scale use. This technology mainly discloses a toilet with testing accessories but does not improve the testing method. Another example is Chinese patent application CN108680507A, which discloses a urine testing device for a toilet and a toilet with urine testing function. This solution incorporates a test strip box and an automatic device within the toilet, requiring manual test strip dispensing, which is inconvenient for the elderly and children. However, it lacks a corresponding solution for large-scale urine testing involving public interest. Furthermore, existing technologies for urine testing devices integrated with toilets primarily focus on individualized and convenient designs. Improvements to the testing method are mainly concentrated on reagents and test boxes, without considering the overall approach to improving the effectiveness and efficiency of urine testing.

[0006] Therefore, there is a need to design a urine testing device that is conducive to public use and can improve testing efficiency.

[0007] The technical problem to be solved by the present invention is to provide an adaptive follow-up detection device and method to fill the gap in the prior art and make batch urine testing and large-scale urine screening possible.

[0008] An adaptive follow-up detection device includes:

[0009] A conveying component is configured to carry a detection plate and to move the detection plate within a certain range and along a certain path through its own movement or partial movement; and,

[0010] A dot-on assembly is configured to drop a sample to be tested onto a detection plate at a defined position on a conveying assembly; the detection plate onto which the sample to be tested is dropped then undergoes a plate-running process; and,

[0011] A data acquisition component is configured to track a specified detection board, acquire the board's running status, and send the acquired running status to a server. The server is configured to recognize the running status and output running results. The data acquisition component is also configured to change or continuously track the detection board's status based on the running results.

[0012] A movable component is configured to carry and move the acquisition component.

[0013] The core problem of this invention is to solve how to identify multiple detection plates at once, while taking into account the different running speeds and reading times of each detection plate. Furthermore, this invention can avoid various problems associated with random urine sampling in public places, such as the unsanitary and embarrassing nature of urine testing, the potential for sample falsification in self-testing, and the slow feedback speed of submission or manual testing, leading to complicated follow-up processing after a positive result.

[0014] Furthermore, the conveying assembly includes a conveyor wheel and a conveyor belt, the conveyor belt is provided with multiple inspection stations, and the inspection plate is limited at the inspection stations.

[0015] Furthermore, the dot plate assembly is fixedly installed above the starting end of the conveying assembly.

[0016] Furthermore, the dotting assembly includes a dropper and a sensor, the dropper being connected to the sample pool via a connecting structure and configured to obtain samples from the sample pool.

[0017] Furthermore, the dotting assembly also includes a dotting drive structure configured to drive the dropper to dispense liquid in response to the detection result of the sensor.

[0018] Furthermore, the moving component is disposed above the conveying component, and the moving component is provided with a translation device. The acquisition component is movably mounted on the moving component via the translation device and is configured such that the distance between the acquisition component and the conveying component satisfies the condition that the acquisition component can acquire at least one complete pattern of a detection plate.

[0019] Furthermore, the acquisition component is a camera device with real-time shooting and transmission functions.

[0020] Preferably, to improve the acquisition accuracy, the height of the acquisition component is set such that the distance from each test plate placement position (test station) on the transmission component to the camera is exactly the focal length of the camera. Since the present invention is equipped with a movable acquisition component, the focal length will not change no matter how the acquisition component moves, provided that the relative height of the transmission component and the acquisition component remains unchanged. Furthermore, it can accurately acquire clear images of the test plates for the server to read.

[0021] Preferably, the detection plate is a drug detection plate, which is configured to detect at least two drugs simultaneously. For example, multiple test strips can be set on the same drug detection plate. Of course, there are also technologies in the prior art that allow one test strip to detect multiple drugs at the same time. The present invention does not require any improvement to the drug detection plate itself.

[0022] This invention also provides an adaptive follow-up detection method, which uses the above-mentioned adaptive follow-up detection device to detect drugs in urine samples. The method specifically adopts the following steps:

[0023] Step (1): The conveying component is started, and the test boards are sent to the spotting station in sequence. The spotting component performs spotting on each test board that passes through the spotting station. In this invention, the conveying component can be in the form of a conveyor belt. The test boards can be placed on the conveying component in advance, or they can be placed on the conveying component one by one by a robot or manually. When the conveying component is started, it can drive the test boards to move. The movement of the test boards is mainly to allow more test boards to enter the conveying component and be included in the detection range, so as to form simultaneous detection of multiple test boards.

[0024] Step (2): When the first detection board is touched, the acquisition device is started. Here, starting means moving synchronously with the movement of the detection board and taking a picture of the detection board at intervals of a certain time, such as 30 seconds. The captured image is sent to the server via wired or wireless means. The server performs real-time online reading of the board through image analysis. The most critical step in this invention is that, with the assistance of the moving component, the acquisition device can move back and forth in the direction of the movement of the detection board to track and acquire images of each detection board after it is touched. After each detection board is touched, the touching component will send a touching signal to the server. The server can then send a tracking command to the acquisition device, and the acquisition device will include the detection board in the tracking acquisition range and send the acquired image to the server in real time.

[0025] As a preferred option, since multiple detection boards need to be monitored simultaneously, each detection board can be distinguished by setting a corresponding label, such as a QR code. That is, when operating the board, the code is scanned and the information is entered. After the acquisition device collects the data, the acquired image can be matched with the code and entered into the corresponding detection board directory.

[0026] Step (3): The server performs real-time image reading of the received pattern and feeds back the reading results to the acquisition device in real time. The server can perform real-time online reading of the pattern using basic image recognition methods. The acquisition component acquires the pattern of the detection plate. In fact, the core part is the pattern of the detection area. The possible situations of the pattern of the detection area are "C line present, T line absent", "CT line present", "C line absent, T line present", and "CT line absent (blank)". Among them, "C line present, T line absent", "CT line present", and "C line absent, T line present" indicate that the plate running has been completed, while "CT line absent (blank)" may be two situations. One is that the plate running has not been completed, so the result has not been produced. The other is that the plate running has been completed, but the test strip has not reacted, which is actually an invalid result. In practice, according to the requirements of sample plate running in drug testing, a time threshold can be set. When this time threshold is exceeded, "CT line absent (blank)" is considered to be a plate running result and will no longer be tracked and read. Since online reading technology is a common image processing method in the existing technology, and since online reading only needs to determine whether horizontal lines appear in the detection area and the control area, it is also a relatively simple image recognition and processing method. Therefore, this invention will not elaborate on this content. This part of the technology can follow the existing technology or be simply developed. The core protection point of this invention is the follow-up detection method.

[0027] Preferably, while tracking one detection board, the acquisition device can also track multiple detection boards simultaneously according to a set time or number. For example, if the reading result of any one of the detection boards changes to "read" within a certain time, the acquisition device will abandon tracking that detection board and continue to add new detection boards as tracking objects.

[0028] Step (4): The acquisition device responds in real time based on the reading result. When the reading result is "read", the acquisition device abandons the tracking of the detection board and tracks the next detection board according to the board order.

[0029] The beneficial effects of this invention are:

[0030] (1) The present invention designs a transmission structure that can accommodate multiple detection plates at the same time, making it possible for multiple people to conduct simultaneous detection, which can greatly enhance the social effect of drug detection.

[0031] (2) The present invention designs a plate-dotting device that can automatically dot the plate. When a sample comes, the plate-dotting device can automatically sense and dot the sample, which greatly improves the real-time performance and convenience of the detection.

[0032] (3) The present invention designs a follow-up acquisition device. After the board is completed, the acquisition device immediately performs real-time online reading of the board. Moreover, the device can follow the board until the reading result is obtained. Through the design of automatic board selection and automatic board reading, the present invention completely liberates the manpower of the test and can achieve better timeliness. Once the server reads a positive result, it can make a rapid feedback.

[0033] (4) The following acquisition device of the present invention can track multiple detection boards at the same time. The acquisition device can adaptively select to track or abandon based on the reading results of the detection boards, which greatly improves the detection efficiency. Attached Figure Description

[0044] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be noted that the embodiments are only specific descriptions of the present invention and should not be regarded as limitations on the present invention.

[0045] Example 1, refer to Appendix Figure 1-5 .

[0046] This embodiment provides an adaptive follow-up detection device that can be installed in public restrooms in locations such as airports and train stations. The device can be installed within public restrooms / toilets / urinals or concealed within walls, and can collect wastewater after the equipment has been used for drug detection. This invention emphasizes providing a device that can be used in conjunction with the aforementioned equipment; however, this invention does not provide improvements to the device itself, nor does it provide improvements made to the device to be combined with this invention. Such improvements can be new technical solutions independent of this invention, which the applicant will protect through other patent applications. Furthermore, the installation of the aforementioned locations or equipment can be considered one application scenario of this invention, but this invention is not limited to the aforementioned application scenario and can also be applied to other locations.

[0047] This invention first includes at least one conveying component, which may include a conveyor belt 1 or a flow strip, etc. The conveyor belt 1 is driven by a conveyor wheel 2. Multiple parallel placement positions 4 for detection plates 3 are provided on the conveyor belt 1. The placement positions 4 serve as the plate-pointing station during the plate-pointing operation and as the detection station during the plate-running process after plate-pointing. The placement positions 4 can be grooves 10 that match the shape and size of the detection plates 3, or they can be baffles or other structures that partially block the detection plates 3, allowing the detection plates 3 to move with the conveyor belt 1 without falling off. Since the conveyor belt 1 moves at a relatively slow speed and within a small range, the possibility of vibration is also relatively small. Therefore, the limiting requirements for the detection plates 3 on the placement positions 4 are not high; it is sufficient that the detection plates 3 can move with the conveyor belt 1.

[0048] Furthermore, in this invention, the internal parameters of the conveying components must have a certain correlation. The length L of the conveyor belt 1 must be sufficient to allow a detection plate 3 to remain on the conveyor belt 1 for a set time t (usually the time required for the plate to run). Figure 2 As shown, assuming the distance from the starting placement position (the position where the detection plate 3 is placed) to the edge of the conveyor belt 1 is x, then the length L of the conveyor belt 1 needs to satisfy L>x+vt to ensure that each detection plate can be located on the conveyor belt 1 and can be detected within the running time. When the set running time has passed, it is considered that reading the plate again is invalid, and the detection plate 3 can fall off the conveyor belt 1. A collection box 5 can be set at the end of the conveyor belt 1, and the used detection plate 3 is disposed of as medical waste.

[0049] Of course, in some preferred embodiments, the conveyor belt 1 of the present invention can also be configured as a ring. In this case, the length of the conveyor belt 1 does not need to be considered. Instead, a device is needed to remove or reject the detection plates 4 that have been read or are invalid from the conveyor belt 1.

[0050] The present invention also includes at least one dotting plate assembly, the function of which is to drip the sample to be tested onto a detection plate at a defined position on the conveying assembly, and the detection plate on which the sample to be tested is dripped then runs. Generally speaking, the present invention needs to be installed in a concealed location in a public toilet, so as not to affect the normal use of the public toilet, and also to avoid causing psychological burden to the person being tested. Therefore, all the components of the present invention are not installed in a visible position in the public toilet, but can be selectively installed behind the wall in a cubicle or similar location. Whenever a urinal or similar device is used, the built-in sensor flushes the urinal, activating the sampling device behind the wall. The sample is drawn from the wastewater outlet and transported through pipes to the spotting assembly or a sample storage tank, where it is then applied to the sample. It should be noted that during the use of this invention, multiple urinals may share a single testing device. Even if multiple urinals do not share the same device, it is unavoidable for the same urinal to share a spotting assembly or storage tank. Furthermore, in public places where test samples may appear at any time, it is impractical to clean the device after each sampling or replace the sampling assembly or dropper / aperture after each sampling. The testing device in this invention, acting as a preliminary screen, allows for a small risk of cross-contamination within a sample cluster, even if positive samples exist within a short period or device. Moreover, the urinal is automatically flushed after each use, so even if cross-contamination occurs, it will only occur between 1-2 closely spaced samples. With repeated flushing, the sample concentration decreases, fully meeting the requirements for preliminary screening.

[0051] like Figure 1As shown, the dot plate assembly is fixedly installed above the starting point of the conveyor assembly. In this embodiment, taking a straight conveyor belt as an example, a starting point is artificially set for easy observation. This starting point is located at one end of the conveyor assembly, which facilitates the placement of the plate and the overall arrangement of the structure. The first placement position 4 at this starting point is called the initial placement position. Before the entire system is started, a new detection plate 3 is pre-placed at the initial placement position. When the urinal is flushed, the flushing signal is sent to the server as an initial signal. The server sends an instruction to the sampling device. It should be noted that the sampling device in the prior art, such as a sewage pipe sampling device, can be used in this invention. The sampling device randomly samples. At the same time, the server also sends an instruction signal to the dot plate assembly. After receiving the instruction signal, the dot plate assembly delays for t1 (sampling time) before performing the dot plate operation. The delay time is determined according to the sampling time of the sampling assembly. Generally, the sampling time of the sampling assembly is determined by the model and specifications of the sampling assembly. Once the sampling assembly is determined, the sampling time is basically determined. Therefore, the sampling and dot plate operations can be controlled by the acquisition of a single signal.

[0052] The spotting assembly also includes an injection pump 6, which is connected to the sampling device 11 (sample pool) via a connecting structure and is configured to obtain samples from the sample pool. The sampling device can have its own sample pool, or it can directly deliver sampled wastewater to the injection pump 6 for dripping. Alternatively, the spotting assembly can take other forms, such as a drip tube, with a robotic arm grasping the drip tube and placing it into the sample pool for spotting. When the spotting assembly uses the injection pump 6, the injection pump 6 can be directly controlled by the server for spotting. When the spotting assembly uses a drip tube, other tools, such as the aforementioned robotic arm, can be used to assist in the dripping operation by receiving signals from the server.

[0053] Once any dripping operation is completed in the system, the acquisition component 7 is activated. Similarly, the acquisition component can automatically activate after a set delay time t2 (drip time, typically 0.5-1 second). In some preferred embodiments, the acquisition component can determine whether dripping has occurred by capturing images. If the determination is that dripping has occurred, it activates tracking mode; that is, the camera of the acquisition device activates tracking mode, moving along the moving component to track the designated detection plate 3, and at certain acquisition intervals t3 (e.g., 30-45 seconds), captures a full-view image of the detection plate (in running state), and sends it to the server. Figure 3The diagram shows the acquisition component tracking the designated detection board. In state (a), the detection board 3 has just completed the test and entered the detection station. In state (b), the detection board 3 moves and the acquisition device moves with it. The tracking of a single detection board 3 continues until the pattern acquired by the acquisition device 7 is fed back by the server as the reading result position. The acquisition time t3 can be a time set manually according to the normal board running situation, or it can be adjusted according to the actual situation.

[0054] After the server receives the pattern sent by the acquisition component 7, it performs real-time online reading and sends the reading results back to the acquisition component. The reading results are as follows: Figure 4 As shown, where, Figure 4 (a) shows "C line present, T line absent", indicating that the test run has been completed and the result is positive. Figure 4 (b) shows "CT lines are all present", indicating that the plate test has been completed and the result is negative. Figure 4 (c) shows "No C line, present T line". This indicates that the test strip test has been completed, but the result is invalid. This may be due to the test strip itself or other reasons. Although it is an invalid result, it still means that a result has been obtained. Figure 4 When the reading results shown in (a)-(c) are displayed, the server reports "read". After receiving the "read" signal, the acquisition component abandons tracking the read detection board and continues tracking the next detection board. The detection board that is abandoned will naturally fall into the collection box 5 below as the conveyor belt moves down when it reaches the end of the conveyor belt 1. It should be noted here that... Figure 4 (d) shows "No CT lines (blank)". In this case, there are two possibilities: one is that the CT scan has finished running, but no CT lines are displayed, which is actually an invalid result; the other possibility is that the CT scan has not finished running, therefore no lines appear. In this case, image recognition alone is insufficient for identification. To solve this problem, this invention sets an invalid time t4 based on the CT scan invalid time (e.g., invalid reading after 15 minutes). Within the invalid time t4, if a result such as... Figure 4 As shown in (d), the acquisition device will continue to acquire the detection board pattern according to the set interval time until other results appear or the invalid time t4 is exceeded. Because once the invalid time t4 is exceeded, the result is considered invalid by default. In addition, if the length of the conveyor belt 1 is set just right, the invalid time t4 is equal to the time it takes for a detection board 3 to travel the entire conveyor belt L. When the invalid time t4 is exceeded, the detection board 3 falls off the conveyor belt 1 and becomes a waste board.

[0055] Furthermore, preferably, the acquisition component 7 can simultaneously track multiple detection plates 3. For example, during a certain time period, such as when an airplane lands, the number of people using the airport restrooms will surge, resulting in a continuous influx of new samples. Consequently, the number of detection plates 3 on the conveyor belt 1 will continuously increase. It is highly likely that before the acquisition device has even completed tracking the first detection plate 3-1, several more detection plates will have been added to the conveyor belt 1. In this case, the acquisition device can move back and forth. For example, the acquisition device 7 can first track the first detected plate 3-1, and so on. Figure 5 As shown in state (a), a single tracking time t5 is set. If within the single tracking time t5, such as Figure 5 If no results were found (the server did not return a "read" result), then... Figure 5 As shown in state (b), the acquisition device 7 returns to the spacing h (the distance between the two placement positions 4), acquires data from the next detection plate 3-2, and then returns to the first tracking object to continue acquisition. Figure 5 In state (c), as the number of subsequent detection boards increases, the acquisition device can continuously collect data from subsequent detection boards (3-3, 3-4, ..., 3-n, where n is the number of detection boards) within the specified acquisition time t3. Figure 5 (as shown in state (d)), but eventually it will return to the initial detection board 3-1 (state (c)) until 3-1 exceeds the invalid time t4 or obtains a "read" result.

[0056] The acquisition device 7 simultaneously tracks the tracking status of multiple detection plates, such as... Figure 5 As shown, where Figure 5 (a) indicates the state of the first inspection plate after it enters the inspection station (3-1 point plate).

[0057] In practice, if the detection frequency is too high and the operating speed of a single detection device cannot keep up with the sampling speed, multiple detection devices can be used to operate simultaneously.

[0058] In this invention, the acquisition component 7 can be a camera device with real-time shooting and transmission capabilities. Preferably, to improve acquisition accuracy, such as... Figure 2 As shown, the height setting of the acquisition component 7 meets the condition that the distance H from each detection plate placement position (detection station) on the transmission component to the camera is exactly the focal length of the camera. Since the present invention is equipped with a movable acquisition component, the focal length will not change no matter how the acquisition component moves, provided that the relative height between the transmission component and the acquisition component remains unchanged. Furthermore, it can accurately acquire clear images of the detection plates for the server to read. Of course, in practice, a Z-axis can also be set for the acquisition component 7 according to the actual situation for height and distance adjustment.

[0059] In order to drive the acquisition component 7 to move along the direction of the conveyor belt 1, the present invention provides a moving component, which is located above the conveyor component. The moving component is provided with a translation device 7, which can be a lead screw or other structure. The translation device is driven by a driving device 9, which can be a motor or other equipment, to provide power for the movement of the acquisition component.

[0060] In this invention, the detection plate is typically as follows: Figure 5 The detection plate shown is sometimes configured to detect at least two drugs simultaneously. For example, multiple test strips can be set on the same detection plate. Of course, there are also existing technologies that allow one test strip to detect multiple drugs at the same time. The image recognition in this invention can be adjusted according to the type of detection plate, but the detection method and principle remain unchanged.

[0061] Example 2, refer to Appendix Figure 7 .

[0062] In this embodiment, the detection plate 3 is fixed to the conveyor belt 1 by means of adhesive or the like. When the conveyor belt 1 is started, the detection plate 3 moves synchronously with the movement of the conveyor belt 1. The conveyor belt 1 can move in steps according to the spacing h between the detection areas of the detection plate 3. Furthermore, the detection plate 3 can stop for a waiting time t6 after moving to a position. During the waiting time t6, the detection plate 3 at the starting end can be used for a point operation, which also facilitates the acquisition device 7 to acquire the image of the detection area on the detection plate 3.

[0063] This invention is typically designed for unattended and automated operation after setup, with manual monitoring as a secondary measure. If a robotic arm is used to place the detection plate, on the one hand, the robotic arm needs to grasp and align precisely, which places high demands on its accuracy and naturally increases the cost. On the other hand, when the detection volume is large, the robotic arm's operation interval is very short, which can easily lead to deviations or interference, hindering normal operation.

[0064] To address this issue, in this embodiment, the detection plate 3 is configured to remain fixed to the conveyor belt 1 throughout the entire operation. The conveyor belt 1 can also be customized to have the detection plates 3 already fixed to it at equal intervals. In this implementation, to reduce operational burden and prevent excessive local thickness of the conveyor belt 1, the detection plate 3 can be simplified to a detection strip 3', which is directly pasted or printed onto the surface of the conveyor belt 1. Figure 7 As shown.

[0065] As a preferred option, such as Figure 8 As shown, the conveyor belt 1 can be in the form of a roll. Upon initial use, a roll of conveyor belt 1 is hung on one of the conveyor wheels 2, as shown. Figure 8As shown in state (a), the outer end of conveyor belt 1 is then pulled out and fixed to another conveyor wheel 2' by means of adhesive or other methods, as follows. Figure 8 As shown in state (b), in this embodiment, the drive wheel 2' can act as the driving wheel, rotating in steps under the drive of the stepper motor 12. Whenever a new sample enters the system, the conveyor belt 1 advances one step. The used detection plates 1 are gradually wound onto the drive wheel 2' and collected as the conveyor belt 1 advances. Figure 8 As shown in state (c), it does not need to be collected through a waste bin, so the whole process can run automatically without human intervention.

[0066] Preferably, specifications can be set for each roll of conveyor belt 1. For example, the number of detection strips 3' on a roll of conveyor belt 1 can be 50 / 100 / 200, etc., or can be set according to actual conditions. Counting sensors or position sensors can be set at the transmission wheel 2' or other positions in the system. For example, the counting sensor can record the number of detection strips 3' used. When the last detection strip 3' is used or reaches the vicinity of the transmission wheel 2', an alarm is sent to the server to remind the monitoring personnel to replace the conveyor belt 1. In this way, the whole process can run automatically without human intervention, and the cost of use can be greatly reduced compared to a robotic arm.

[0067] In this embodiment, the tracking and acquisition method of the acquisition device 7 is the same as that in embodiment 1.

[0068] Example 3, refer to Appendix Figure 7 .

[0069] This embodiment provides an adaptive follow-up detection method, which uses the device described in Embodiment 1 and specifically includes the following steps:

[0070] S1, the conveyor component starts and sends the test boards to the board inspection station in sequence. The board inspection component performs inspection on each test board that passes through the board inspection station.

[0071] In this embodiment, the conveying component can be in the form of a conveyor belt. One detection plate 3 can be pre-placed on the conveyor belt 1. Subsequent detection plates can be placed onto the conveying component one by one using a robotic arm or manually. When the conveyor belt starts, it can move the detection plates. The movement of the detection plate 1 is mainly to allow more detection plates to enter the conveying component and be included in the detection range, thus enabling simultaneous detection of multiple plates. Each detection plate is initially at the spot detection station when it enters the conveyor belt.

[0072] S2, once the first detection board is detected, the acquisition device is immediately activated and takes a picture of the detection board at certain intervals, such as 30 seconds. The captured image is sent to the server via wired or wireless means, and the server performs real-time online board reading through image analysis.

[0073] In step S2, the acquisition device can move back and forth in the direction of the detection plate movement with the assistance of the moving device to track and acquire images of the detection plate after each detection plate is touched. After each detection plate is touched, the acquisition device will include the detection plate in the tracking acquisition range according to the server's instructions or preset settings, and send the acquired images to the server in real time.

[0074] As a preferred option, since multiple detection boards need to be monitored simultaneously, each detection board can be distinguished by setting a corresponding label, such as a QR code. That is, when operating the board, the code is scanned and the information is entered. After the acquisition device collects the data, the acquired image can be matched with the code and entered into the corresponding detection board directory.

[0075] S3, the server performs real-time image reading of the received pattern and feeds back the reading results to the acquisition device in real time. The server can perform real-time online pattern reading using basic image recognition methods. The acquisition component acquires the pattern of the detection plate, the core of which is the pattern of the detection area. The pattern of the detection area may show "C line present, T line absent", "CT lines present", "C line absent, T line present", and "CT lines absent (blank)". Among them, "C line present, T line absent", "CT lines present", and "C line absent, T line present" indicate that the plate run is complete, while "CT lines absent (blank)" may be due to two situations: one is that the plate run is not yet complete, so no result is generated; the other is that the plate run is complete, but the test strip does not react, which is actually an invalid result. In practice, according to the requirements of sample plate run in drug testing, a time threshold can be set. When this time threshold is exceeded, "CT lines absent (blank)" is considered a plate run result and is no longer tracked and read. Since online reading technology is a common image processing method in the existing technology, and since online reading only needs to determine whether horizontal lines appear in the detection area and the control area, it is also a relatively simple image recognition and processing method. Therefore, this invention will not elaborate on this content. This part of the technology can follow the existing technology or be simply developed.

[0076] Preferably, while tracking one detection board, the acquisition device can also track multiple detection boards simultaneously according to a set time or number. For example, if the reading result of any one of the detection boards changes to "read" within a certain time, the acquisition device will abandon tracking that detection board and continue to add new detection boards as tracking objects.

[0077] S4, the acquisition device responds in real time based on the reading result. When the reading result is "read", the acquisition device abandons the tracking of the detection board and tracks the next detection board according to the board order.
