Description

Technical Field

[0001] The present invention relates to the technical field of sample analysis, and in particular to a sample analysis scheduling system and a scheduling method for an automatic analyzer. Background Art

[0002] In the automatic analyzer used for clinical examination, it is used to automatically analyze and examine the indicated analysis items of the test sample such as blood, plasma, serum, urine, and other body fluids. When the automatic analyzer performs the test analysis, the sample rack containing the sample container is positioned and transferred to the sample suction position of the analysis unit by the conveying line.

[0003] Typically, since the sample racks are transported and analyzed on the transport line in the order in which they are moved in from the rack supply unit, it is not possible to prioritize the transport of urgent samples requiring expedited analysis to the analysis unit, making it impossible to meet the transfer requirements of sample containers and sample racks of different priority levels, thus delaying the detection time of expedited analysis. In addition, the lack of overall planning function makes it difficult to increase the test throughput. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the present invention aims to provide an automatic analyzer analysis sample scheduling system and scheduling method, which has the advantage of being able to meet the needs of graded detection of analysis samples of different priorities.

[0005] The purpose of the present invention is achieved by the following technical solutions: According to a first aspect of an embodiment of the present disclosure, there is provided a system for scheduling sample analysis by an automatic analyzer, comprising: Sample delivery and buffering track, used to transfer and buffer samples to be tested; The sample feeding and transfer track has at least a first sample feeding port and a second sample feeding port, wherein the first sample feeding port is connected to the discharge end of the sample feeding and buffering track and is used to receive and transfer the sample to be tested, and a barcode scanning device is provided on the sample feeding and transfer track for scanning and identifying the sample barcode and registering it to the host computer to determine the sample priority; An emergency transfer track connected to the second sample inlet and used to transfer the emergency sample, and when a sample is delivered to the emergency transfer track, the first sample inlet stops receiving the sample; A detection buffer track, connected to the sample feeding and transfer track, for temporarily storing samples to wait for transfer to the detection unit for detection; A cache transfer unit connected to the detection cache track and used to select and cache low-priority samples or transfer high-priority samples according to the priority determined by the host computer; A cyclic transfer track, which is docked with the buffer transfer unit and used to carry the sample with the highest current priority. The cyclic transfer track is used to be docked with the detection unit to transfer the sample with the highest current priority to the detection unit for detection and analysis; and, A sample return unit for returning the tested sample.

[0006] To implement the above technical solution, the samples to be normally detected and analyzed are fed into the sample transfer track through the first sample inlet from the sample feeding buffer track. The samples can be transferred and buffered in the sample feeding buffer track to ensure continuous sample feeding. In the sample transfer track, the barcode on the sample is scanned and identified by the barcode scanning device and registered on the host computer. The host computer determines the priority of the sample according to the scanned barcode information. Then the sample is fed into the detection buffer track by the sample transfer track and waits for the buffer transfer unit to receive it. The buffer transfer unit selects to temporarily buffer the sample with a lower priority or transfer the sample with a higher priority to the cyclic transfer track according to the priority of the sample. Thus, the sample on the cyclic transfer track is the sample with the highest current priority. The detection unit sequentially takes out the samples from the cyclic transfer track for detection and analysis according to the detection order, and returns them to the cyclic transfer track after the detection is completed. Finally, the sample return unit sends out the tested sample, enabling the detection process to proceed continuously; while the samples that need to be urgently detected are fed from the emergency transfer track. At this time, when there is a sample fed into the emergency transfer track, the sample feeding from the first sample inlet is stopped, and the sample on the emergency transfer track is preferentially fed into the sample transfer track from the second sample inlet. At this time, since the host computer will also determine that the current sample has the highest priority, the buffer transfer unit will also preferentially feed the sample into the cyclic transfer track and then be preferentially detected and analyzed by the detection unit; through the above process, the purpose of grading and detecting samples according to different priorities is achieved, the samples that need to be urgently detected can be preferentially detected, the overall detection order is optimized, and the test throughput is improved.

[0007] In some exemplary embodiments, two or more groups of the sample feeding buffer tracks are provided, including: a sample inlet area for feeding in new samples and a buffer area for buffering the fed samples.

[0008] To implement the above technical solution, the new samples are conveyed forward by the sample inlet area, and the buffer area buffers the fed samples, so as to ensure that the detection process can proceed continuously.

[0009] In some exemplary embodiments, a first sample inlet sensor is provided at the docking position of each of the sample transfer tracks and the sample feeding buffer tracks. The sample feeding buffer tracks corresponding to the first sample inlet sensors have different priorities and are stored in the host computer. The host computer allows the samples to enter the sample transfer track in sequence according to the predetermined priority order.

[0010] To implement the above technical solution, by setting up multiple groups of sample delivery cache tracks, samples of different priorities can be transferred and cached respectively, and each first sample feeding sensor can detect whether there is a sample to be delivered to each sample delivery cache track. Since the host computer stores different priority orders of the sample delivery cache tracks corresponding to each first sample feeding sensor, the samples can be allowed to be delivered to the sample feeding transfer track in sequence according to the different priority orders, thereby realizing sample supply according to priority, and then meeting the needs of detection according to different priorities.

[0011] In some exemplary embodiments, the sample is contained in a test tube, and several test tubes are loaded in a test tube rack for transfer, the sample barcode includes a test tube barcode and a test tube rack barcode, and the scanning device includes: a tube code scanner for scanning the test tube barcode, and a rack code scanner for scanning the test tube rack barcode.

[0012] The above technical solution is implemented to achieve scanning and acquisition of pipe codes and rack codes.

[0013] In some exemplary embodiments, a second sample injection sensor is provided at the entrance of the emergency transfer track. When the second sample injection sensor detects a sample injection signal, the sample injection transfer track stops receiving samples from the sample delivery buffer track and gives priority to receiving samples on the emergency transfer track.

[0014] To implement the above technical solution, the second sample injection sensor can be used to determine whether there is a sample being delivered to the emergency transfer track. When the second sample injection sensor detects the injection signal, it stops receiving samples from the sample delivery buffer track, thereby achieving priority reception and detection of samples on the emergency transfer track.

[0015] In some exemplary embodiments, the cache transfer unit includes: a connection area connected to the detection cache track, a transfer track connected to the connection area, and a cache module corresponding to the transfer track, wherein the transfer track is connected to the circulation transfer track; If it is determined that the sample in the connection area has the highest priority, it is directly transferred to the circulation transfer track through the transfer track; If it is determined that there is a sample with a higher priority outside the connection area, the sample in the connection area is transferred to the cache module through the transfer track; If it is determined that the priority of the sample in the connection area is lower than or equal to the priority of the sample in the cache module, the sample in the cache module is transferred to the circulating transfer track via the transfer track.

[0016] To implement the above technical solution, the transfer area is used for the transfer and connection of the test samples. The transfer track is used to realize the transfer of test samples between the transfer area, the buffer module and the circular transfer track. The buffer module can buffer the test samples with low priority during the transfer process, ensuring that the test samples with high priority can enter the circular transfer track first for the detection unit to detect and analyze preferentially.

[0017] In some exemplary embodiments, the sample return unit includes a first sample return track, a second sample return track and an unloading track that are connected in sequence. The first sample return track is connected to the circular transfer track or connected to the transfer track through the transfer area.

[0018] Implementing the above technical solution can transfer the test samples that have completed the detection in an orderly manner, ensuring the orderly progress of the detection process.

[0019] According to a second aspect of the embodiments of the present disclosure, there is provided an automatic analyzer test sample scheduling method, which is implemented based on the system as described in the first aspect, and includes: Obtain the sample injection detection signal in real time to initially judge the priority of the test sample, and receive the test sample with the highest priority onto the sample injection transfer track; Scan and identify the barcode information of the test sample to secondarily judge the priority of the test sample, so that the buffer transfer unit can select to buffer the test sample with low priority or transfer the test sample with high priority to the circular transfer track; Periodically send the test samples on the circular transfer track into the detection unit for detection and analysis, and return them through the sample return unit after the detection is completed.

[0020] In some exemplary embodiments, the initial judgment of the priority of the test sample specifically includes: The host computer judges the priority order of the test samples according to the priority order of the sample delivery buffer tracks corresponding to each of the first sample injection sensors stored in advance, or judges that the test sample is of the highest priority when detecting the detection signal of the second sample injection sensor.

[0021] In some exemplary embodiments, the buffer transfer unit selecting to buffer the test sample with low priority or transfer the test sample with high priority to the circular transfer track specifically includes: If it is judged that the test sample in the transfer area has the highest priority, it is directly transferred to the circular transfer track through the transfer track; If it is judged that there is a test sample with a higher priority outside the transfer area, the test sample in the transfer area is transferred to the buffer module through the transfer track; If it is judged that the priority of the test sample in the transfer area is lower than or equal to the priority of the test sample in the buffer module, the test sample in the buffer module is transferred to the circular transfer track through the transfer track.

[0022] In summary, compared with the prior art, the present invention has the following beneficial effects: In the embodiment of the present invention, by providing an automatic analyzer sample scheduling system and a scheduling method, samples to be detected normally are fed into the sample transfer track through the first sample inlet from the sample feeding buffer track. The samples can be transferred and buffered in the sample feeding buffer track to ensure continuous sample feeding. In the sample transfer track, the barcode on the sample is scanned and identified by a barcode scanning device and registered on the host computer. The host computer determines the priority of the sample according to the barcode information scanned and identified. Subsequently, the sample is fed into the detection buffer track by the sample transfer track and waits for the buffer transfer unit to receive it. The buffer transfer unit selects to temporarily buffer the sample with a low priority or transfer the sample with a high priority to the circulation transfer track according to the priority of the sample. Thus, the sample on the circulation transfer track is the sample with the highest current priority. The detection unit sequentially takes out the samples from the circulation transfer track for detection and analysis according to the detection sequence, and sends them back to the circulation transfer track after the detection is completed. Finally, the sample return unit sends out the samples after the detection is completed, so that the detection process can continue; while the samples that need to be urgently detected are fed into from the emergency transfer track. At this time, when a sample is fed into the emergency transfer track, the access of samples from the first sample inlet is stopped, and the sample on the emergency transfer track is preferentially fed into the sample transfer track through the second sample inlet. At this time, since the host computer will also determine that the current sample has the highest priority, the buffer transfer unit will also preferentially feed the sample into the circulation transfer track and then be preferentially detected and analyzed by the detection unit; through the above process, the purpose of classifying and detecting samples according to different priorities is achieved, the samples that need to be urgently detected can be preferentially detected, the overall detection sequence is optimized, and the test throughput is improved.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 3 As shown, the first aspect of the embodiment of the present invention provides an automatic analyzer analysis sample scheduling system, including: a sample delivery buffer track, used to transfer and buffer samples to be tested; a sample injection transfer track 105, which has at least a first injection port and a second injection port, the first injection port is connected to the discharge end of the sample delivery buffer track, and is used to receive and transport samples to be tested, and a barcode scanning device is provided on the sample injection moving track, which is used to scan and identify the sample barcode and register it to the host computer to determine the sample priority; an emergency transfer track 103, which is connected to the second injection port and is used to transfer emergency samples, and when a sample is delivered to the emergency transfer track 103, the first injection port stops receiving the sample. Sample; a detection cache track 24, connected to the sample transfer track 105, for temporarily storing samples waiting to be transferred to the detection unit 30 for detection; a cache transfer unit, connected to the detection cache track 24, for selecting to cache low-priority samples or transfer high-priority samples according to the priority determined by the host computer; a circulating transfer track 28, connected to the cache mobile unit, for carrying the sample with the highest current priority, and the circulating transfer track 28 is used to connect to the detection unit 30 to transfer the sample with the highest current priority to the detection unit 30 for detection and analysis; and a sample return unit, for returning the sample after detection.

[0029] Specifically, there are two or more sets of sample feeding buffer tracks. In this embodiment, two sets are provided, including a first sample feeding buffer track and a second sample feeding buffer track. Each sample feeding buffer track includes: a sample loading area for loading new samples, and a buffer area for buffering the loaded samples. The sample enters the sample loading transfer track 105 from the buffer area, and the buffer area is the discharge end of the sample feeding buffer track. That is, in this embodiment, the first sample feeding buffer track correspondingly includes a first sample loading area 111 and a first buffer area 109. A first sample feeding push arm 1111 is provided on the first sample loading area 111, and the first sample feeding push arm 1111 is used to push the sample forward on the first sample loading area 111. A first buffer push claw 1091 is provided on the first buffer area 109, and the first buffer push claw 1091 is used to push the sample forward on the first buffer area 109. The second sample feeding buffer track correspondingly includes a second sample loading area 110 and a second buffer area 108. A second sample feeding push arm 1101 is provided on the second sample loading area 110, and the second sample feeding push arm 1101 is used to push the sample forward on the second sample loading area 110. A second buffer push claw 1081 is provided on the second buffer area 108, and the second buffer push claw 1081 is used to push the sample forward on the second buffer area 108. The first sample feeding push arm 1111, the first buffer push claw 1091, the second sample feeding push arm 1101, and the second buffer push claw 1081 can all adopt existing pushing structures, such as electric push rods, screw pushing structures, or belt pushing structures, etc. The new sample is transported forward from the sample loading area, and the buffer area buffers the loaded samples, so as to ensure that the detection process can proceed continuously.

[0030] A first sample loading sensor 1052 is provided at the docking position of the sample loading transfer track 105 and each sample feeding buffer track. The sample feeding buffer tracks corresponding to each first sample loading sensor 1052 have different priorities and are stored in the upper computer. The upper computer allows the samples to enter the sample loading transfer track 105 in sequence according to a predetermined priority order. The first sample loading sensor 1052 can adopt, for example, a photoelectric sensor. By setting multiple sets of sample feeding buffer tracks, samples with different priorities can be transported and buffered respectively. Each first sample loading sensor 1052 is used to detect whether there is a sample in each sample feeding buffer track that needs to be sent. Since the upper computer stores the different priority orders of the sample feeding buffer tracks corresponding to each first sample loading sensor 1052, samples can be allowed to enter the sample loading transfer track 105 in sequence according to different priority orders, thus realizing sample feeding according to priority and further meeting the requirement of detecting according to different priorities. That is, different sample feeding buffer tracks have different priorities, and this priority order is stored in the upper computer. When the first sample loading sensor 1052 detects a sample, the upper computer judges the priority of the corresponding sample feeding buffer track and then allows the sample feeding buffer track with the highest priority to load the sample.

[0031] During the transfer process, the test samples are contained in test tubes, and several test tubes are loaded into a test tube rack for transfer. The sample barcodes include test tube barcodes and test tube rack barcodes. The barcode scanning device includes: a tube barcode scanner 107 for scanning test tube barcodes, and a rack barcode scanner 106 for scanning test tube rack barcodes, so as to realize the scanning and acquisition of tube barcodes and rack barcodes. Usually, the priority judgment is made based on the rack barcode.

[0032] At the entrance of the emergency transfer track 103, there is a second sample injection sensor 1031. The second sample injection sensor 1031 can also be in the form of a photoelectric sensor, etc. When the second sample injection sensor 1031 detects a sample injection signal, the sample injection transfer track 105 stops receiving samples from the sample delivery buffer track and preferentially receives samples on the emergency transfer track 103. Through the second sample injection sensor 1031, it can be judged whether there are samples sent on the emergency transfer track 103. When the second sample injection sensor 1031 detects a sample injection signal, it stops receiving samples from the sample delivery buffer track, realizing the preferential reception and detection of samples on the emergency transfer track 103.

[0033] The buffer transfer unit includes: a connection area 23 connected to the detection buffer track 24, a transfer track 26 connected to the connection area 23, and a buffer module 21 corresponding to the transfer track 26. The transfer track 26 is connected to the circular transfer track 28; the transfer sequence of the buffer transfer unit is as follows: If it is judged that the priority of the sample in the connection area 23 is the highest, it is directly transferred to the circular transfer track 28 through the transfer track 26; If it is judged that there are samples with higher priority outside the connection area 23, the samples in the connection area 23 are transferred to the buffer module through the transfer track 26; If it is judged that the priority of the sample in the connection area 23 is lower than or equal to the priority of the sample in the buffer module, the sample in the buffer module is transferred to the circular transfer track 28 through the transfer track 26.

[0034] The connection area 23 is used for the transfer connection of samples. The transfer track 26 is used to realize the transfer of samples between the connection area 23, the buffer module and the circular transfer track 28. The buffer module can cache samples with lower priority during the transfer process, ensuring that samples with higher priority can enter the circular transfer track 28 first for priority detection and analysis by the detection unit 30.

[0035] Among them, the connection area 23 is usually set as a transfer track with a gripper, and a clamping gripper 27 is provided between the connection area 23 and the detection buffer track 24 for grasping the sample from the detection buffer track 24 to the connection area 23. A claw 22 is provided between the transfer track 26 and the buffer module 21 for realizing the transfer action of the sample between the buffer module 21 and the transfer track 26. A guide rod mechanism 261 is provided between the transfer track 26 and the circulating transfer track 28 for realizing the transfer of the sample between the transfer track and the circulating transfer track 28. One side of the circulating transfer track 28 close to the transfer track 26 is a transfer inlet 281. The circulating transfer track 28 is divided into a transfer injection section 282 and a transfer sample return section 283 for temporarily storing the samples to be tested and the samples after the detection is completed respectively. A transfer push arm 284 is further provided on the circulating transfer track 28 for realizing the transfer of the sample on the circulating transfer track 28.

[0036] The detection unit 30 is provided with a detection transfer track 31 therein, and transfer devices such as a three-axis robot, a clamping transfer mechanism or a pushing structure can be provided in the detection unit 30 to grasp the sample from the transfer injection section 282 of the circulating transfer track 28 to the detection transfer track 31 for detection and transfer, or to grasp the sample after the detection is completed from the detection transfer track 31 to the transfer sample return section 283 of the circulating transfer track 28 for sample return.

[0037] The sample return unit includes a first sample return track 25, a second sample return track 104 and an unloading track which are connected in sequence. The first sample return track 25 is connected to the circulating transfer track 28 or connected to the transfer track 26 through the connection area 23, so as to be able to transfer the samples after the detection is completed in an orderly manner and ensure the orderly progress of the detection process.

[0038] Specifically, the end of the first sample-return track 25 is docked with the second sample-return track 104, and the second sample-return track 104 extends to the unloading track. In this embodiment, preferably two sets of unloading tracks are provided, namely the first unloading track 101 and the second unloading track 102. A first unloading hook 1011 is provided on the first unloading track 101 for pushing and moving the sample on the first unloading track 101, and a second unloading hook 1021 is provided on the second unloading track 102 for pushing and moving the sample on the second unloading track 102. In order to detect the position of the sample on the second sample-return track 104, sample-out sensors are respectively provided at the positions of the second sample-return track 104 corresponding to the first unloading track 101 and the second unloading track 102. The sample-out sensors can also be in the form of photoelectric sensors, etc. In some embodiments, in order to make the overall layout more compact and reduce space occupation, the unloading track can be arranged side by side with the sample-feeding buffer track and has a certain height difference from the emergency transfer track 103. For example, the unloading track is arranged below the emergency transfer track 103, and the second sample-return track 104 can be arranged in a liftable form to be docked with the first sample-return track 25, or an inclined transfer section can be provided on the second sample-return track 104 to be docked with the first sample-return track 25.

[0039] In the present invention, the samples to be detected and analyzed normally are sent from the sample-feeding buffer track into the sample-in transfer track 105 through the first sample-in port. The samples can be transferred and buffered in the sample-feeding buffer track to ensure continuous sample feeding. In the sample-in transfer track 105, the barcodes on the samples are scanned and identified by a barcode scanning device and registered on the host computer. The host computer judges the priority of the samples according to the scanned barcode information. Subsequently, the samples are sent from the sample-in transfer track 105 into the detection buffer track 24 for temporary storage waiting for the buffer transfer unit to receive. The buffer transfer unit selects to temporarily buffer the samples with low priority or transfer the samples with high priority to the circular transfer track 28 according to the priority of the samples. Thus, the samples on the circular transfer track 28 are the samples with the highest current priority. The detection unit 30 sequentially takes out the samples from the circular transfer track 28 for detection and analysis according to the detection sequence, and sends them back to the circular transfer track 28 after the detection is completed. Finally, the sample return unit sends out the samples after the detection is completed, so that the detection process can continue. The samples that need to be detected urgently are sent from the emergency transfer track 103. At this time, when there are samples sent on the emergency transfer track 103, the access of samples from the first sample-in port is stopped, and the samples on the emergency transfer track 103 are preferentially sent into the sample-in transfer track 105 from the second sample-in port. At this time, since the host computer will also judge that the current sample has the highest priority, the buffer transfer unit will also preferentially send the sample into the circular transfer track 28 and then be preferentially detected and analyzed by the detection unit 30. Through the above process, the purpose of grading and detecting samples according to different priorities is achieved. The samples that need to be detected urgently can be preferentially detected, the overall detection sequence is optimized, and the test throughput is improved.

[0040] The specific sample injection and detection process of the present invention is as follows: First, it is preferentially judged whether the second sample injection sensor 1031 at the emergency transfer track 103 is triggered. If it is triggered, the sample rack on the emergency transfer track 103 is transported first. When the emergency transfer track 103 is sent to the sample injection transfer track 105, it needs to obtain the permission of the sample injection transfer track 105, that is, there should be no sample rack being transported on the sample injection transfer track 105.

[0041] Second, the first buffer pusher 1091 is preferentially pushed to the end, so that the sample rack on the first buffer area 109 enters the sample injection transfer track 105 and is transported in sequence until there is no sample rack on the first buffer area 109. When the first buffer area 109 is sent to the sample injection transfer track 105, it needs to obtain the permission of the sample injection transfer track 105, that is, there should be no sample rack being transported on the sample injection transfer track 105.

[0042] Third, the second buffer pusher 1081 is pushed to the end, so that the sample rack on the second buffer area 108 enters the sample injection transfer track 105 and is transported in sequence until there is no sample rack on the second buffer area 108. When the second buffer area 108 is sent to the sample injection transfer track 105, it needs to obtain the permission of the sample injection transfer track 105, that is, there should be no sample rack being transported on the sample injection transfer track 105.

[0043] Then, the first sample delivery push arm 1111 and the second sample delivery push arm 1101 are respectively pushed to the end, and the sample racks on the first buffer area 109 and the second buffer area 108 are continuously pushed in sequence according to the above process until all the sample racks to be injected enter the sample injection transfer track 105.

[0044] After the sample rack enters the sample injection transfer track 105, it is successively hooked by the sample injection push arm 1051 to the rack code scanning position and 5 sample tube code scanning positions, and registered to the upper computer. The upper computer determines the priority according to different rack codes; after the scanning is completed, the sample injection transfer track 105 needs to wait for the injection permission of the detection buffer track 24. After receiving the permission, the sample injection push arm 1051 continues to move and sends the sample rack to the detection buffer track 24.

[0045] When the sample rack enters the detection buffer track 24, it is necessary to judge whether the number of empty spaces in the buffer module 21 is not less than 2 grids at this time. If it is not less than 2 grids, the detection buffer track 24 requests the clamping gripper 27 to be in place, otherwise it needs to wait for sample return again; after the clamping gripper 27 is in place, the detection buffer track 24 transports the sample rack to the clamping position on the detection buffer track 24.

[0046] The clamping gripper 27 transports the sample rack to the transfer track 26 and requests the hook 22 to be in place.

[0047] After the claw 22 is in place, it hooks the sample rack onto the claw bracket on the transfer track 26. At this time, the claw 22 will move the sample rack to different positions according to the priority of the sample rack code and the sample injection status allowed by the transfer track 26. That is, if the transfer track 26 allows sample injection and the priority of the sample rack transported by the claw 22 is the highest at present, the claw 22 will move to the transfer track 26; if sample injection is not allowed or the priority of the sample rack transported by the claw 22 is not the highest at present, the claw 22 will transfer the sample rack to the buffer module 21. The positions and priorities of the sample racks stored in the buffer module 21 are stored one-to-one by the computer. If it is judged that there is a vacancy in the test tube rack position, according to the priority, the claw 22 will move to the position of the test tube rack with the highest priority, take out the sample rack, and transmit it to the detection unit 30 through the transfer track 26.

[0048] After the sample rack is sent to the transfer track 26 by the claw 22, the guide rod mechanism 261 on the transfer track 26 pushes the sample rack into the circulating transfer track 28. The circulating transfer track 28 requests the pushing structure of the detection unit 30 to act. After the pushing structure of the detection unit 30 is in place, the circulating transfer track 28 sends the sample rack to the transfer injection section 282 of the circulating transfer track 28.

[0049] The pushing structure of the detection unit 30 moves the sample rack to the detection transfer track 31. Subsequently, the push arm structure on the detection transfer track 31 pushes the sample rack according to the sampling period of the current sample.

[0050] This is the whole process of sample injection into the main unit.

[0051] During the sample withdrawal process: The sample rack is pushed by the push arm on the detection transfer track 31 at the detection unit 30 to the sample withdrawal part of the detection transfer track 31. At this time, the detection transfer track 31 requests sample withdrawal. When the circulating transfer track 28 and the transfer track 26 are not occupied, the push arm on the detection transfer track 31 moves the sample rack to the transfer withdrawal section 283 of the circulating transfer track 28.

[0052] After the sample rack is moved to the transfer withdrawal section 283 of the circulating transfer track 28, the circulating transfer track 28 transports the sample rack in the reverse direction to the transfer entrance of the circulating transfer track 28. Subsequently, the push arm of the circulating transfer track 28 pushes the sample rack to the transfer track 26.

[0053] After the sample rack enters the transfer track 26 from the circulating transfer track 28, the transfer track 26 requests the claw 22 to be in place.

[0054] After the claw 22 is in place, the sample rack is hooked to the claw bracket. At this time, according to the priority of the sample racks to be returned and whether the gripper transfer track 26 is occupied, the sample racks are transported to the buffer module 21 or the gripper transfer track 26 respectively. When requesting the same mechanism to be in place, returning samples takes precedence over loading samples. If the gripper transfer track 26 is not occupied, the claw 22 moves the sample rack to the position of the gripper transfer track 26 and requests the gripper to be in place. After the gripper is in place, the claw 22 hooks the sample rack to the transfer track 26.

[0055] The gripper clamps and requests the lifting mechanism of the detection buffer track 24 to descend. Subsequently, the clamping gripper 27 moves the sample rack to the first sample return track 25.

[0056] After the sample rack is moved to the first sample return track 25, the belt of the first sample return track 25 transports the sample rack to the end of the first sample return track 25, and controls the first unloading hook 1011 and the second unloading hook 1021 to be in place.

[0057] According to the loading conditions of the sample racks to be returned on the first unloading track 101 and the second unloading track 102, the first unloading hook 1011 and the second unloading hook 1021 are respectively called to be in place. Among them, the first unloading track 101 is preferentially loaded. After the first section of the first unloading track 101 is full, the second unloading track 102 is loaded. After the first section of the second unloading track 102 is full, the second section of the first unloading track 101 is loaded, and finally the second section of the second unloading track 102 is loaded.

[0058] If the first unloading hook 1011 is called to be in place, the belt of the first sample return track 25 transports the sample rack to the second sample return track 104. The belt of the second sample return track 104 transports the sample rack to its end, and the first unloading hook 1011 hooks the sample rack to the first section of the first unloading track 101 in sections.

[0059] In this way, the entire sample return process is completed.

[0060] The second aspect of the embodiment of the present invention provides an automatic analyzer analysis sample scheduling method, which is implemented based on the system in the first aspect, and includes: S100. Obtain the sample injection detection signal in real time to initially judge the priority of the sample, and receive the sample with the highest priority onto the sample injection transfer track 105.

[0061] Specifically, initially judging the priority of the sample specifically includes: the upper computer judges the priority order of the samples according to the priority order of the sample delivery buffer tracks corresponding to each first sample injection sensor 1052 stored in advance, or judges that the sample is of the highest priority when the detection signal of the second sample injection sensor 1031 is recognized; it can be understood that the priority during sample injection controls the sample injection in the order of the samples detected by the second sample injection sensor 1031 and the samples detected by the first sample injection sensor 1052.

[0062] S200 scans and identifies the barcode information of the sample to re-determine the priority of the sample, so that the cache transfer unit can select to cache the samples with low priority or transfer the samples with high priority to the circular transfer track 28.

[0063] Specifically, the cache transfer unit selecting to cache the samples with low priority or transfer the samples with high priority to the circular transfer track 28 specifically includes: If it is determined that the sample in the connection area 23 has the highest priority, it is directly transferred to the circular transfer track 28 through the transfer track 26; If it is determined that there are samples with higher priority outside the connection area 23, the samples in the connection area 23 are transferred to the cache module through the transfer track 26; If it is determined that the priority of the sample in the connection area 23 is lower than or equal to the priority of the sample in the cache module, the sample in the cache module is transferred to the circular transfer track 28 through the transfer track 26.

[0064] S300 periodically sends the samples on the circular transfer track 28 into the detection unit 30 for detection and analysis, and returns them through the sample return unit after the detection is completed.

[0065] Through the above process, the purpose of grading and detecting samples according to different priorities is achieved. Samples that need to be urgently detected can be preferentially detected, the overall detection order is optimized, and the test throughput is improved.

[0066] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can be made. These are all equivalent modifications and evolutions made to the above embodiments based on the essence of the present invention, and these all belong to the protection scope of the present invention.
