Description

Technical Field

[0001] The present invention relates to the field of medical machinery, and in particular to a sample rack scheduling method, a scheduling system, and an analysis system. Background Art

[0002] In clinical biochemical immunology applications, blood or urine samples are transported in sample racks through a sample dispatching system to the sample analyzer's sample aspiration station for analysis and testing of the sample's chemical composition. Taking a biochemical immunology analysis pipeline as an example, it typically consists of an analysis unit, a sample dispatching system, and an operation unit. The analysis unit analyzes analytes in serum, plasma, and other human fluids; the sample dispatching system handles sample loading, code scanning, dispatching, transporting, locating, and recovering the sample racks containing the samples; and the operation unit controls the software of the analysis unit and sample dispatching system, completing the input of test items, the output of test results, analysis of results, and quality control.

[0003] During a normal test, the sample rack testing process is as follows: sample injection - barcode information acquisition - dispatch and distribution - transfer to the sample aspiration station in the analysis section - return after test completion - dispatch and distribution - return to the recycling area. Sample rack dispatch and distribution is a key step that impacts the efficiency of the dispatch system. Currently, conventional sample rack dispatch and distribution devices in the industry utilize a mobile dispatch and distribution structure that can be freely switched between various workstations. However, this dispatch is limited to dispatching only one sample rack at a time. Existing manufacturers currently lack an efficient sample rack dispatch judgment mechanism to address this issue. Consequently, significant time is wasted in the sample rack dispatch and distribution process, impacting sample injection efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a sample rack scheduling method, scheduling system and analysis system, aiming to solve the problem that the existing sample rack scheduling and distribution process is relatively time-consuming, resulting in low sampling efficiency.

[0005] To solve the above technical problems, the present invention aims to achieve the following technical solutions: providing a sample rack scheduling method, comprising:

[0006] Acquire the sample rack injection position of the sample rack to be triggered for injection and the sample type of the sample rack to be triggered for injection and generate trigger information;

[0007] Determining the scheduling priority of the sample rack according to the trigger information, and controlling the scheduling distribution device to move to the corresponding sample rack injection position according to the injection priority of the sample rack;

[0008] Transferring the sample rack from the sample rack injection position to the scheduling and distributing device;

[0009] The sample rack is moved to a target location via the scheduling and distributing device.

[0010] In addition, the technical problem to be solved by the present invention is to provide a sample rack scheduling system, comprising:

[0011] An information acquisition unit, configured to acquire the sample rack injection position to be triggered for injection and the sample type of the sample rack to be triggered for injection and generate trigger information;

[0012] a moving unit, configured to determine the scheduling priority of the sample rack according to the trigger information, and control the scheduling distribution device to move to the corresponding sample rack injection position according to the injection priority of the sample rack;

[0013] A transfer unit, configured to transfer the sample rack from the sample rack injection position to the scheduling and distributing device;

[0014] A scheduling unit is used to move the sample rack to a target position via the scheduling distribution device.

[0015] In addition, an embodiment of the present invention further provides a sample analysis system, comprising the sample scheduling system as described above, and further comprising an analysis module and an operation unit;

[0016] The analysis module includes one of a full biochemical analysis unit combination composed of multiple biochemical analysis units, a full immune analysis unit combination composed of multiple immune analysis units, and a biochemical and immune analysis unit combination composed of multiple biochemical analysis units and immune analysis units;

[0017] The operating unit connects the analysis module, the track area, and the scheduling area. The operating unit is used to obtain sample test information, location information, and sample rack scheduling instructions. The operating unit is used to receive sample test results, respond to user intervention operations, and control the scheduling process of sample racks between the track area and the scheduling area.

[0018] Embodiments of the present invention disclose a sample rack scheduling method, scheduling system, and analysis system. The method includes: obtaining trigger information for a sample rack sample feed position; controlling a scheduling and distribution device to move to the corresponding sample rack sample feed position based on the trigger information; transferring the sample rack from the sample rack sample feed position to the scheduling and distribution device; and transferring the sample rack to a target position via the scheduling and distribution device. The sample rack scheduling judgment mechanism provided in the embodiments of the present invention enables the scheduling and distribution device to schedule and distribute sample racks to the maximum extent possible, thereby reducing the residence time of sample racks within the system, improving the operating efficiency of the sample processing system, and meeting the demand for the shortest possible sample rack turnover time in clinical applications.

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0043] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the present invention. As used in the specification and appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0044] It should be further understood that the term "and / or" used in the present description and appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0045] An embodiment of the present invention provides a sample rack scheduling method for use in biochemical and immunological clinical testing. The sample rack scheduling method enables a scheduling and distribution device to schedule and distribute sample racks to the maximum extent possible, thereby saving the residence time of sample racks in the system, improving the operating efficiency of the sample processing system, and meeting the demand for the shortest possible sample rack turnover time in clinical applications.

[0046] To facilitate understanding of the sample rack scheduling method according to an embodiment of the present invention, the scheduling system is first introduced:

[0047] refer to Figure 17 and Figure 18 The sample scheduling system includes a scheduling area, a track area 108, a recycling channel 106, a recycling area 107, and a track change area 109; the scheduling area is connected to the track area 108, the recycling channel 106, and the recycling area 107, respectively, and the track area 108 is connected to the track change area 109;

[0048] The scheduling area includes a placement area 101, an injection channel 102, an emergency area 103, a sample buffer 104, and a scheduling distribution device 105. The placement area 101 is connected to the injection channel 102, and the scheduling distribution device 105 is respectively connected to the injection channel 102, the emergency area 103, the sample buffer 104, the track area 108, and the recovery channel 106;

[0049] The placement area 101 is used to place the sample rack to be injected;

[0050] The injection channel 102 is used for injecting samples into the sample rack to be injected;

[0051] Emergency area 103 is used to place emergency sample racks and non-emergency sample racks that need priority scheduling;

[0052] The sample buffer 104 includes at least one sample buffer position for storing sample racks, which is used for temporarily storing sample racks in various test states;

[0053] The dispatching and distributing device 105 is used to transfer and transport the sample racks between the dispatching area and the track area 108. The dispatching and distributing device 105 has a Y-axis bidirectional motion function and can freely switch between the track position of the track area 108 and the buffer position of the sample buffer area 104. The positioning method includes but is not limited to the use of positioning code teeth. Figure 19, is a structural layout diagram of the scheduling and distribution device 105. The scheduling and distribution device includes a carrying track 203 and a guide groove 202 for the bidirectional entry, exit and retention of sample racks, and includes a corresponding sample rack transfer device 201 (the specific structure is not shown), which has a bidirectional X-axis movement function and can transfer the sample rack from the sample loading position to the scheduling and distribution device carrying track.

[0054] Track area 108 includes at least three parallel tracks, specifically an emergency track 108-1, a conventional track 108-2, and a return track 108-3. Up to four tracks are also possible, with the fourth track serving as a sample transfer channel. Emergency track 108-1 and conventional track 108-2 are connected to return track 108-3 via a track change area 109. Emergency track 108-1 includes an emergency track sample aspiration area with an emergency track sample aspiration position. Conventional track 108-2 includes a conventional track sample aspiration area with a conventional track sample aspiration position. Conventional channel 108-2 may also include at least one pre-sample aspiration waiting position. When a sample rack at a conventional track sample aspiration position initiates its return, the sample rack at the pre-sample aspiration waiting position can be immediately introduced to the conventional track sample aspiration position. The movement of sample racks within track area 108 can be controlled by a conveyor belt, grabbed by a robotic arm, or propelled by a propulsion mechanism.

[0055] Specifically, the sample is placed in the scheduling area through the sample rack, which is a carrying mechanism. The scheduling area is responsible for uploading, downloading, scheduling, and buffering the sample. As an independent module, it is generally placed on the side of the analyzer. No matter how many analysis units are interconnected, there is only one sample scheduling system.

[0056] refer to Figure 17 and Figure 18 The running track of the sample rack is shown in the figure. The sample rack in the placement area 101 moves to the dispatching and distributing device 105 via the sample inlet channel 102. The sample rack in the emergency area 103 can directly reach the dispatching and distributing device 105. The dispatching and distributing device 105 can then transport the sample rack to the regular track 108-2 or the emergency track 108-1 for sample aspiration. After the sample aspiration is completed, the sample rack is transported back to the dispatching and distributing device 105 via the return track 108-3 and dispatched to the recycling area 107. The user can remove the sample rack from the recycling area 107. Typically, the sample rack and sample tube (container for storing samples) are provided with barcode labels. When the sample rack arrives at the dispatching and distributing device 105, it will be scanned by a barcode scanner (not shown in the figure) to obtain the sample rack information and sample information.

[0057] The sample scheduling system also includes a sample input module and a sample output module;

[0058] refer to Figure 17,The sampling module includes an emergency sampling position 1, a regular sampling position 2, a sample buffer position 3, and a return track position 4;

[0059] Emergency sample loading position 1 is the position in the emergency area for placing sample racks and waiting for them to be called out;

[0060] Conventional injection position 2 is the position in the injection channel for the sample rack to wait for being called out;

[0061] Sample buffer position 3 is a position in the sample buffer for temporarily storing sample racks and waiting to be called out;

[0062] Return track position 4 is a position in the return track for the sample rack to be called out.

[0063] It can be understood that when the sample rack reaches the corresponding sample loading position, the scheduling action process of the scheduling and distribution device is triggered, and the scheduling and distribution device moves from the previous working stop position to the corresponding sample rack sample loading position. Before reaching the corresponding sample rack sample loading position, the sample rack stays and waits at the corresponding sample rack sample loading position.

[0064] refer to Figure 18 The sample output module includes a conventional track sample output position 5, an emergency track sample output position 6, a sample buffer position 7, and a recovery channel sample output position 8, wherein the sample buffer position can be used as a sample input position or as a sample output position;

[0065] The sample output position on the conventional track is the sample output position when the dispatching and distributing device moves the sample rack to the conventional track;

[0066] The emergency track sample output position is the sample output position when the dispatching distribution device transfers the sample rack to the emergency track;

[0067] The sample buffer position is the sample output position when the scheduling distribution device moves the sample rack to the sample buffer;

[0068] The sample output position of the recycling channel is the sample output position when the scheduling distribution device moves the sample rack to the recycling channel.

[0069] It can be understood that when the sample rack enters the scheduling and distribution device through each sample rack sample input position, it must correspond to a sample output position. When the sample rack has not reached the designated sample output position, the sample rack remains stationary on the carrying track of the scheduling and distribution device. When it reaches the designated sample output position, the transfer action of the sample rack can be started.

[0070] The above is an introduction to the sample scheduling system.

[0071] Next, based on the above sample scheduling system, the sample scheduling method provided by the embodiment of the present invention is introduced. Figure 1 , Figure 1 A schematic flow chart of a sample rack scheduling method provided in an embodiment of the present invention;

[0072] like Figure 1 As shown, the method includes steps S101 to S104.

[0073] S101, obtaining the sampling position of the sample rack to be triggered for sampling and the sample type of the sample rack to be triggered for sampling and generating trigger information;

[0074] In this step, after the sample rack reaches the sample rack injection position, the corresponding sample rack injection position can be triggered. When triggered, the corresponding trigger information can be generated by obtaining the sample rack injection position to be triggered and the sample type of the sample rack that triggers the injection. That is, the trigger information includes injection information of at least one sample rack injection position and one sample type.

[0075] S102, determining the scheduling priority of the sample rack according to the trigger information, and controlling the scheduling distribution device to move to the corresponding sample rack injection position according to the injection priority of the sample rack;

[0076] In this step, the trigger information includes the injection information of at least one sample rack, that is, currently only one sample rack injection position is triggered for injection or multiple sample rack injection positions are triggered for injection at the same time. Based on this, there are many different triggering situations. For various triggering situations, it is necessary to first determine the scheduling priority of the sample racks that are triggered for injection at the same time, and control the scheduling distribution device to move to the corresponding sample rack injection position in the order of high to low scheduling priority.

[0077] S103, transferring the sample rack from the sample rack injection position to the scheduling and distributing device;

[0078] S104: Move the sample rack to the target location via the scheduling and distributing device.

[0079] In steps S103-S104, the scheduling and distributing device needs to receive the sample rack from the sample rack input position and move it to the target position, which is the corresponding sample output position.

[0080] The sample rack scheduling method provided in this embodiment enables the scheduling and distribution device to schedule and distribute sample racks to the maximum extent possible, thereby saving the residence time of sample racks in the system, improving the operating efficiency of the sample processing system, and meeting the demand for the shortest possible sample rack turnover time in clinical applications.

[0081] The following describes the scheduling and distribution of sample racks for different trigger information. For ease of understanding, the scheduling priority judgment mechanism used in the following embodiment is first introduced. That is, all sample rack injection positions and sample rack types are ranked from high to low in the following order: sample racks to be scheduled in the return track position, emergency sample racks to be scheduled in the sample buffer position, sample racks to be scheduled in the emergency injection position, non-emergency sample racks to be scheduled in the sample buffer position, and sample racks to be scheduled in the regular injection position.

[0082] In one embodiment, step S102 includes a description of the situation when only one sample rack injection position is triggered to inject a sample, which may specifically include:

[0083] When the trigger information indicates that only the emergency sampling position is triggered for sampling, the control scheduling distribution device moves from the last working stop position to the emergency sampling position. When the trigger information indicates that only one sample rack sampling position among the emergency sampling position, regular sampling position, sample buffer position, and return track position is triggered for sampling, the control scheduling distribution device moves from the last working stop position to the sample rack sampling position that is triggered for sampling.

[0084] In this embodiment, when a single sample rack injection position is triggered for injection, the sample rack is scheduled according to the order in which the sample rack injection positions are triggered. For example, if the regular injection position is triggered for scheduling and then the return track position is triggered for scheduling, the sample rack scheduling process for the regular injection position is executed first, and then the sample rack scheduling process for the return track position is executed.

[0085] In one embodiment, if Figure 2 As shown, step S102 also includes a description of the situation when two sample rack injection positions are triggered to inject samples, which may specifically include:

[0086] S201, if the trigger information is that the emergency injection position and the regular injection position are triggered to inject simultaneously;

[0087] S202, executing the sample rack scheduling process for the emergency sample loading position;

[0088] S203, after the sample rack scheduling process for the emergency sample injection position is completed, the sample rack scheduling process for the regular sample injection position is executed;

[0089] S204: After the sample rack scheduling process of the regular sample loading position is completed, it is determined whether there is a new sample rack to be scheduled at the emergency sample loading position. If so, the process proceeds to step S205; if not, the process jumps to step S207;

[0090] S205, executing the scheduling process of the sample rack at the emergency sample loading position;

[0091] S206: Determine whether there is a new sample rack to be scheduled at the regular sample loading position. If yes, proceed to step S207; if not, jump to step S208;

[0092] S207, executing the sample rack scheduling process of the regular sample loading position, and returning to step S204 after the execution is completed;

[0093] S208: The scheduling process ends.

[0094] In this embodiment, the conventional sample injection position and the emergency sample injection position are triggered to inject samples at the same time, and two scheduling and distribution methods can be used.

[0095] One method is to first execute the sample rack scheduling process for the emergency sample injection position, then execute the sample rack scheduling process for the regular sample injection position, and then terminate the scheduling process directly, that is, only schedule all sample racks that trigger the injection moment at the same time.

[0096] The other is: first execute the scheduling process of the current sample rack of the emergency sample position, and after the execution is completed, determine whether there are new sample racks at the emergency sample position, that is, consider the situation where new sample racks appear while triggering the injection and scheduling at the same time. In other words, after each execution of the sample rack with the current scheduling priority, it is necessary to return to the judgment step of the highest scheduling priority for repeated judgment until there are no new sample racks at all emergency sample positions and regular sample positions, and the scheduling process ends.

[0097] In one embodiment, if Figure 3 As shown, step S102 also includes a description of the situation when two sample rack injection positions are triggered to inject samples, which may specifically include:

[0098] S301, if the trigger information is that the emergency injection position and the return track position trigger injection at the same time;

[0099] S302, executing the sample rack scheduling process of the return track position;

[0100] S303, after the sample rack scheduling process for the return track position is completed, the sample rack scheduling process for the emergency sample introduction position is executed;

[0101] S304: After the sample rack scheduling process of the emergency sample loading position is completed, it is determined whether there is a new sample rack to be scheduled in the return track position. If so, the process proceeds to step S305; if not, the process jumps to step S307;

[0102] S305, executing the scheduling process of returning to the track position sample rack,

[0103] S306: Determine whether there is a new sample rack to be scheduled at the emergency sample loading position. If yes, proceed to step S307; if not, jump to step S308;

[0104] S307, executing the sample rack scheduling process for the emergency sample loading position, and returning to step S304 after the execution is completed;

[0105] S308: The scheduling process ends.

[0106] In this embodiment, the emergency sample injection position and the return track position are triggered for injection at the same time, that is, when the sample rack to be scheduled arrives at the return track position, the emergency sample injection position is triggered for injection. Two scheduling and distribution methods can be used.

[0107] One method is to first execute the sample rack scheduling process for the return injection position, then execute the sample rack scheduling process for the emergency injection position, and then terminate the scheduling process directly, that is, only schedule all sample racks that trigger the injection moment at the same time.

[0108] The other is: first execute the scheduling process of the current sample rack of the return sample injection position, and after the execution is completed, determine whether there are new sample racks at the return sample injection position, that is, consider the situation where new sample racks appear while triggering injection and scheduling at the same time. In other words, after each execution of the sample rack with the current scheduling priority, it is necessary to return to the judgment step of the highest scheduling priority for repeated judgment until there are no new sample racks at all emergency sample injection positions and return track positions, and the scheduling process ends.

[0109] In one embodiment, if Figure 4 As shown, step S102 also includes a description of the situation when two sample rack injection positions are triggered to inject samples, which may specifically include:

[0110] S401, if the trigger information is that the normal injection position and the return track position trigger injection at the same time;

[0111] S402, executing the sample rack scheduling process of the return track position;

[0112] S403, executing the sample rack scheduling process of the regular sample injection position;

[0113] S404: Determine whether there is a new sample rack to be scheduled at the return track position. If yes, proceed to step S405; if not, jump to step S406;

[0114] S405, executing the sample rack scheduling process for the return track position, and after the execution, proceeding to step S406;

[0115] S406: Determine whether there is a new sample rack to be scheduled at the regular sample loading position. If yes, proceed to step S407; if not, jump to step S408;

[0116] S407, executing the sample rack scheduling process of the regular sample loading position, and returning to step S404 after the execution is completed;

[0117] S408: The scheduling process ends.

[0118] In this embodiment, the regular sample injection position and the return track position are triggered for injection at the same time, that is, the regular sample injection position is triggered for injection when the sample rack to be scheduled reaches the return track position. Two scheduling and distribution methods can be used.

[0119] One method is to first execute the sample rack scheduling process for the return injection position, then execute the sample rack scheduling process for the regular injection position, and then terminate the scheduling process directly, that is, only schedule all sample racks that trigger the injection moment at the same time.

[0120] The other is: first execute the scheduling process of the current sample rack of the return sample input position, and after the execution is completed, determine whether there are new sample racks at the return sample input position, that is, consider the situation where new sample racks appear while triggering the injection and scheduling at the same time. In other words, after each execution of the sample rack with the current scheduling priority, it is necessary to return to the judgment step of the highest scheduling priority for repeated judgment until there are no new sample racks at all regular sample input positions and return track positions, and the scheduling process ends.

[0121] In one embodiment, if Figure 5 As shown, step S102 also includes a description of the situation when two sample rack injection positions are triggered to inject samples, which may specifically include:

[0122] S501, if the trigger information is that the sample buffer position and the return track position trigger the injection simultaneously;

[0123] S502, executing the sample rack scheduling process of the return track position;

[0124] S503, executing the sample rack scheduling process of the sample buffer position;

[0125] S504: Determine whether there is a new sample rack to be scheduled at the return track position. If yes, proceed to step S505; if not, jump to step S506;

[0126] S505, executing the sample rack scheduling process of the return track position, and after the execution, proceeding to step S506;

[0127] S506: Determine whether there is a new sample rack to be scheduled in the sample buffer. If yes, proceed to step S07; if not, jump to step S508;

[0128] S507, executing the sample rack scheduling process of the sample buffer position, and returning to step S504 after the execution is completed;

[0129] S508: The scheduling process ends.

[0130] In this embodiment, the sample buffer position and the return track position are triggered to inject samples simultaneously, that is, the sample buffer position is triggered to inject samples when the sample rack reaches the return track position. Two scheduling and distribution methods can be used.

[0131] One method is to first execute the sample rack scheduling process for the return injection position, then execute the sample rack scheduling process for the sample buffer position injection position, and then the scheduling process ends directly, that is, only scheduling all sample racks at the same time triggering the injection moment.

[0132] The other is: first execute the scheduling process of the current sample rack of the return sample position, and after the execution is completed, determine whether there are new sample racks at the return sample position, that is, consider the situation where new sample racks appear while triggering the injection and scheduling at the same time. In other words, after each execution of the sample rack with the current scheduling priority, it is necessary to return to the judgment step of the highest scheduling priority for repeated judgment until there are no new sample racks in all sample buffer positions and return track positions, and the scheduling process ends.

[0133] In one embodiment, if Figure 6 As shown, step S102 also includes a description of the situation when two sample rack injection positions are triggered to inject samples, which may specifically include:

[0134] S601, if the trigger information is that the sample buffer position and the emergency injection position are triggered to inject at the same time;

[0135] S602: Determine whether there is an emergency sample rack to be dispatched in the sample buffer. If yes, proceed to step S603; if not, jump to step S604;

[0136] S603: Execute the scheduling process for the emergency sample rack currently in the sample buffer, and return to step S602 after completion;

[0137] S604: Determine whether there is a sample rack to be scheduled at the emergency sample loading position. If yes, proceed to step S605; if not, proceed to step S606.

[0138] S605, executing the sample rack scheduling process for the emergency sample loading position, and returning to step S602 after the execution is completed;

[0139] S606: Determine whether there is a sample rack to be scheduled in the sample buffer. If yes, proceed to step S607; if not, proceed to step S608.

[0140] S607, executing the sample rack scheduling process of the sample buffer position, and returning to step S602 after the execution is completed;

[0141] S608: The scheduling process ends.

[0142] In this embodiment, the scheduling priority of the emergency sample racks to be scheduled in the sample buffer is higher than that of the sample racks to be scheduled in the emergency injection position. This is set based on the consideration of reducing sample turnover time. Because sample racks that have not entered the system are not yet included in the turnover time calculation range, while the emergency sample racks to be scheduled in the sample buffer have entered the pre-test waiting period, in order to minimize the sample rack waiting time, the emergency sample racks to be tested in the sample buffer have priority over the sample racks to be scheduled in the emergency injection position.

[0143] It is understandable that for other types of sample racks in the sample buffer (sample rack types may include but are not limited to emergency, calibration, quality control, manual retest, routine, etc.), since the emergency sample injection position has a high priority testing authority, the sample racks to be scheduled in the emergency sample injection position must be scheduled first. When there are no sample racks to be scheduled in the emergency sample injection position, the scheduling process for other types of sample racks in the sample buffer position will be executed.

[0144] Specifically, two scheduling and distribution methods can also be adopted.

[0145] One method is: if there is an emergency sample rack to be scheduled in the sample buffer, the scheduling process of the emergency sample rack to be scheduled in the sample buffer is executed first, and then the scheduling process of the sample rack to be scheduled in the emergency injection position is executed. Finally, if there is a non-emergency sample rack to be scheduled in the sample buffer, the scheduling process of the non-emergency sample rack to be scheduled in the sample buffer is executed, and then the scheduling process ends directly, that is, only all sample racks that are triggered at the same injection moment are scheduled.

[0146] The other method is to schedule in the order of the emergency sample racks in the sample buffer, the sample racks in the emergency injection position, and the non-emergency sample racks in the sample buffer. After each sample rack with the current scheduling priority is executed, it is necessary to return to the judgment step with the highest scheduling priority and repeat the judgment until there are no new sample racks in all sample buffer positions and emergency injection positions. The scheduling process ends.

[0147] In one embodiment, if Figure 7 As shown, step S102 also includes a description of the situation when two sample rack injection positions are triggered to inject samples, which may specifically include:

[0148] S701, if the trigger information is that the sample buffer position and the regular injection position are triggered to inject at the same time;

[0149] S702, executing the scheduling process of the sample rack currently to be scheduled in the sample buffer;

[0150] S703: Determine whether there is a new sample rack to be scheduled in the sample buffer. If yes, proceed to step S704; if not, jump to step S705;

[0151] S704, continue to execute the sample rack scheduling process of the sample buffer position, and return to step S703 after the execution is completed;

[0152] S706, executing the sample rack scheduling process of the regular sample injection position;

[0153] S706: Determine whether there is a new sample rack to be scheduled at the regular sample loading position. If yes, return to step S703; if not, proceed to step S706;

[0154] S706: The scheduling process ends.

[0155] In this embodiment, for the case where the sample buffer position and the regular sample injection position are triggered at the same time, two scheduling and distribution methods can also be used.

[0156] One method is to first execute the sample rack scheduling process for the sample buffer position, then execute the sample rack scheduling process for the regular injection position, and then terminate the scheduling process directly, that is, only schedule all sample racks at the same time when the injection is triggered.

[0157] The other method is: first execute the scheduling process of the current sample rack in the sample buffer position, and after the execution is completed, determine whether there are any new sample racks in the sample buffer position, that is, consider the situation where new sample racks appear while triggering injection and scheduling at the same time. In other words, after each execution of the sample rack with the current scheduling priority, it is necessary to return to the judgment step of the highest scheduling priority for repeated judgment until there are no new sample racks in all regular injection positions and sample buffer positions, and the scheduling process ends.

[0158] This setting is also based on the consideration of reducing the sample rack turnover time within the system, because the sample racks to be scheduled that have entered the sample buffer have entered the test queue. In order to reduce the sample rack turnover time, the sample rack scheduling in the sample buffer is performed first.

[0159] In one embodiment, if Figure 8 As shown, step S102 also includes a description of the situation when the three sample rack injection positions are triggered to inject samples, which may specifically include:

[0160] S801, if the trigger information is that the sample buffer position, the regular injection position and the emergency injection position are triggered to inject at the same time;

[0161] S802: Determine whether there is an emergency sample rack to be dispatched in the sample buffer. If yes, proceed to step S803; if not, jump to step S804.

[0162] S803, executing the scheduling process of the emergency sample rack to be scheduled in the sample buffer, and returning to step S802 after the execution is completed;

[0163] S804: Determine whether there is a sample rack to be scheduled at the emergency sample loading position. If yes, proceed to step S805; if not, jump to step S806;

[0164] S805, executing the sample rack scheduling process for the emergency sample loading position, and returning to step S802 after the execution is completed;

[0165] S806, determine whether there is a sample rack to be scheduled in the sample buffer, if yes, go to step S807, if not, jump to step S808;

[0166] S807, executing the scheduling process of the sample rack to be scheduled in the sample buffer, and returning to step S802 after the execution is completed;

[0167] S808: Determine whether there is a sample rack to be scheduled at the regular sample loading position. If yes, proceed to step S809; if not, jump to step S810.

[0168] S809, executing the scheduling process of the sample rack to be scheduled at the regular sample loading position, and returning to step S802 after the execution is completed;

[0169] S810: The scheduling process ends.

[0170] In this embodiment, when the sample buffer, regular sample feed, and emergency sample feed are triggered to inject samples simultaneously, the following scheduling and distribution method is used: the scheduling process for all the emergency sample racks to be scheduled in the sample buffer is executed first. After all the emergency sample racks to be scheduled in the sample buffer are scheduled, the sample rack scheduling process for the emergency sample feed is executed. If no sample racks to be scheduled in the emergency sample feed are available, the scheduling process for the non-emergency sample racks to be scheduled in the sample buffer is executed. After all the sample racks in the sample buffer are scheduled, the sample rack scheduling process for the regular sample feed is executed. That is, the order is: emergency sample racks to be scheduled in the sample buffer > sample racks to be scheduled in the emergency sample feed > non-emergency sample racks to be scheduled in the sample buffer > sample racks to be scheduled in the regular sample feed.

[0171] It is understandable that after the current sample rack to be scheduled is scheduled, it is necessary to re-determine whether there are new sample racks to be scheduled at the sample rack injection position with high priority and the current sample rack injection position. When there are new sample racks to be scheduled at the sample rack injection position with high priority, the sample rack to be scheduled at the sample rack injection position with high priority must be executed first.

[0172] In one embodiment, if Figure 9 As shown, step S102 also includes a description of the situation when the three sample rack injection positions are triggered to inject samples, which may specifically include:

[0173] S901, if the trigger information is that the return track position, the regular injection position and the emergency injection position are triggered to inject at the same time;

[0174] S902, executing the sample rack scheduling process of the return track position;

[0175] S903, executing the sample rack scheduling process for the emergency sample loading position;

[0176] S904: Determine whether there is a new sample rack to be scheduled at the return track position. If yes, proceed to step S905; if not, jump to step S906;

[0177] S905, executing the sample rack scheduling process for the return track position, and after the execution, proceeding to step S906;

[0178] S906: Determine whether there is a new sample rack to be scheduled at the emergency sample loading position. If yes, proceed to step S907; if not, jump to step S908;

[0179] S907, executing the sample rack scheduling process for the emergency sample loading position, and returning to step S904 after the execution is completed;

[0180] S908, executing the sample rack scheduling process of the regular sample injection position;

[0181] S909, determine whether there is a new sample rack to be scheduled at the regular sample loading position, if yes, return to step S904, if not, go to step S910;

[0182] S910: The scheduling process ends.

[0183] In this embodiment, when the return track position, the regular sample injection position, and the emergency sample injection position trigger injection at the same time, the scheduling and distribution method adopted is: the sample rack scheduling process of the return track position is executed first, and after the sample rack scheduling process of the return track position is completed, the sample rack scheduling process of the emergency sample injection position is executed; when there are no sample racks to be scheduled at both the return track position and the emergency sample injection position, the sample rack scheduling process of the regular sample injection position is executed.

[0184] It is understandable that after the current sample rack to be scheduled is scheduled, it is necessary to re-determine whether there are new sample racks to be scheduled at the sample rack injection position with high priority and the current sample rack injection position. When there are new sample racks to be scheduled at the sample rack injection position with high priority, the sample rack to be scheduled at the sample rack injection position with high priority must be executed first.

[0185] In one embodiment, if Figure 10 As shown, step S102 also includes a description of the situation when the three sample rack injection positions are triggered to inject samples, which may specifically include:

[0186] S1001, if the trigger information is that the return track position, the sample buffer position and the emergency injection position are triggered to inject simultaneously;

[0187] S1002, executing the sample rack scheduling process of the return track position;

[0188] S1003: Determine whether there is an emergency sample rack to be dispatched in the sample buffer. If yes, proceed to step S1004; if not, jump to step S1006;

[0189] S1004, executing the scheduling process of the emergency sample rack to be scheduled in the sample buffer, and after the execution, proceeding to step S1005;

[0190] S1005: Determine whether there is a new sample rack to be scheduled at the return track position. If yes, return to step S1002; otherwise, return to step S1003;

[0191] S1006: Determine whether there is a sample rack to be scheduled at the emergency sample loading position. If yes, proceed to step S1007; if not, jump to step S1008;

[0192] S1007, executing the sample rack scheduling process for the emergency sample loading position, and returning to step S1005 after the execution is completed;

[0193] S1008, determine whether there is a sample rack to be scheduled in the sample buffer, if yes, go to step S1009, if not, jump to step S1010;

[0194] S1009, executing the sample rack scheduling process of the sample buffer position, and returning to step S1005 after the execution is completed;

[0195] S1010. The scheduling process ends.

[0196] In this embodiment, when the sample buffer, return track, and emergency sample injection positions are triggered for injection at the same time, the scheduling and distribution method adopted is: the sample rack scheduling process of the return track position is executed first, and then the scheduling process of all the emergency sample racks to be scheduled in the sample buffer position is executed. After the scheduling of the emergency sample racks to be scheduled in the sample buffer position is completed, the sample rack scheduling process of the emergency sample injection position is executed. When there are no sample racks to be scheduled in the emergency sample injection position, the scheduling process of the non-emergency sample racks to be scheduled in the sample buffer position is executed; that is, the sample racks to be scheduled in the return track position > the emergency sample racks to be scheduled in the sample buffer position > the sample racks to be scheduled in the emergency sample injection position > the non-emergency sample racks to be scheduled in the sample buffer position.

[0197] It is understandable that after the current sample rack to be scheduled is scheduled, it is necessary to re-determine whether there are new sample racks to be scheduled at the sample rack injection position with high priority and the current sample rack injection position. When there are new sample racks to be scheduled at the sample rack injection position with high priority, the sample rack to be scheduled at the sample rack injection position with high priority must be executed first.

[0198] In one embodiment, if Figure 11 As shown, step S102 also includes a description of the situation when the three sample rack injection positions are triggered to inject samples, which may specifically include:

[0199] S1101, if the trigger information is that the sample buffer position, the regular injection position and the return track position trigger injection simultaneously;

[0200] S1102, executing the sample rack scheduling process of the return track position;

[0201] S1103, executing the sample rack scheduling process of the sample buffer position;

[0202] S1104: Determine whether there is a new sample rack to be scheduled at the return track position. If yes, proceed to step S1105; if not, jump to step S906;

[0203] S1105, executing the sample rack scheduling process for the return track position, and after the execution, proceeding to step S1106;

[0204] S1106: Determine whether there is a new sample rack to be scheduled in the sample buffer. If yes, proceed to step S1107; if not, jump to step S1108;

[0205] S1107, executing the sample rack scheduling process of the sample buffer position, and returning to step S1104 after the execution is completed;

[0206] S1108, executing the sample rack scheduling process of the regular sample injection position;

[0207] S1109: Determine whether there is a new sample rack to be scheduled at the regular sample loading position. If yes, return to step S1104; if not, go to step S1100.

[0208] S1110, the scheduling process ends.

[0209] In this embodiment, when the return track position, the regular sample feed position, and the sample buffer position trigger sample injection simultaneously, the scheduling and distribution method used is as follows: the scheduling process for the sample racks to be scheduled in the return track position is executed first. After the sample racks to be scheduled in the return track position are scheduled, the scheduling process for the sample racks to be scheduled in the sample buffer position is executed. After the emergency sample racks to be scheduled in the sample buffer position are scheduled, it is necessary to determine again whether the return track position has sample racks to be scheduled. The sample rack scheduling process for the regular sample feed position is executed only if and only if there are no sample racks to be scheduled in the return track position and no sample racks to be scheduled in the sample buffer position.

[0210] It is understandable that after the current sample rack to be scheduled is scheduled, it is necessary to re-determine whether there are new sample racks to be scheduled at the sample rack injection position with high priority and the current sample rack injection position. When there are new sample racks to be scheduled at the sample rack injection position with high priority, the sample rack to be scheduled at the sample rack injection position with high priority must be executed first.

[0211] In one embodiment, if Figure 2 As shown, step S102 also includes a description of the situation when the four sample rack injection positions are triggered to inject samples, which may specifically include:

[0212] S1201, if the trigger information is that the emergency injection position, the regular injection position, the sample buffer position and the return track position are triggered to inject simultaneously;

[0213] S1202, executing the sample rack scheduling process for the return track position;

[0214] S1203: Determine whether there is an emergency sample rack to be dispatched in the sample buffer. If yes, proceed to step S1204; if not, jump to step S1206;

[0215] S1204: Execute the scheduling process for the emergency sample racks in the sample buffer, and after the execution, proceed to step S1205.

[0216] S1205: Determine whether there is a new sample rack to be scheduled at the return track position. If yes, return to step S1202; if not, return to step S1203;

[0217] S1206: Determine whether there is a sample rack to be scheduled at the emergency sample loading position. If yes, proceed to step S1207; if not, jump to step S1208;

[0218] S1207, executing the scheduling process of the sample rack to be scheduled at the emergency sample injection position, and returning to step S1205 after the execution is completed;

[0219] S1208: Determine whether there is an emergency sample rack to be dispatched in the sample buffer. If yes, proceed to step S1209; if not, jump to step S1210;

[0220] S1209: Execute the scheduling process for the emergency sample rack to be scheduled in the sample buffer, and return to step S1205 after the execution is completed;

[0221] S1210, determine whether there is an emergency sample rack to be dispatched at the regular sample loading position, if yes, proceed to step S1211, if not, jump to step S1212;

[0222] S1211, executing the scheduling process of the emergency sample rack to be scheduled at the regular sample loading position, and returning to step S1205 after the execution is completed;

[0223] S1212: The scheduling process ends.

[0224] In this embodiment, when the sample buffer, return track, emergency sample introduction, and regular sample introduction are triggered to be injected at the same time, the scheduling and distribution method adopted is as follows: the sample rack scheduling process of the return track is executed first, and then the scheduling process of all the emergency sample racks to be scheduled in the sample buffer is executed. After the scheduling of the emergency sample racks to be scheduled in the sample buffer is completed, the sample rack scheduling process of the emergency sample introduction is executed. If there are no sample racks to be scheduled in the emergency sample introduction, the scheduling process of the non-emergency sample racks to be scheduled in the sample buffer is executed. After the scheduling of the sample racks to be scheduled in the return track, emergency sample introduction, and sample buffer is completed, the sample rack scheduling process of the regular sample introduction is executed, that is, the sample racks to be scheduled in the return track > the emergency sample racks to be scheduled in the sample buffer > the sample racks to be scheduled in the emergency sample introduction > the non-emergency sample racks to be scheduled in the sample buffer > the sample racks to be scheduled in the regular sample introduction.

[0225] It is understandable that after the current sample rack to be scheduled is scheduled, it is necessary to re-determine whether there are new sample racks to be scheduled at the sample rack injection position with high priority and the current sample rack injection position. When there are new sample racks to be scheduled at the sample rack injection position with high priority, the sample rack to be scheduled at the sample rack injection position with high priority must be executed first.

[0226] The above is an explanation of the scheduling and distribution of sample racks for different trigger information, specifically listing the process of scheduling sample racks that are triggered for injection at the same time, as well as the scheduling process when new samples appear in the injection position of a sample rack that is triggered for injection separately during the scheduling process.

[0227] The following further illustrates another situation, namely:

[0228] The control scheduling and distribution device executes the scheduling process of the sample racks that are currently triggering the injection according to the scheduling priority. If a new sample rack triggers the injection position of other sample racks during the execution process, the scheduling priority of the new sample rack is determined, and the new sample rack is added to the scheduling process of the remaining sample racks according to its scheduling priority.

[0229] In this case, the newly entered sample rack triggers the sampling positions of other sample racks, that is, the sampling position of the sample rack triggered this time is different from the sampling position of the sample rack triggered at the same time before. Preferably, the newly entered sample rack and the corresponding sampling position of the sample rack can also be scheduled and judged, and then added to the scheduling process of the current remaining sample racks according to their scheduling priority.

[0230] In one embodiment, step S103 of transferring the sample rack from the sample rack injection position to the scheduling and dispensing device includes:

[0231] Locate the hook position of the sample rack;

[0232] The hooking device on the scheduling and distributing device locks the hooking position of the sample rack and hooks it, driving the sample rack to be transferred to the scheduling and distributing device.

[0233] Specifically, refer to Figure 20 , is a top-down perspective of the sample rack to be scheduled moving process, with the arrow direction in the figure as the moving direction. The method of transferring the sample rack to be scheduled by the hooking device on the scheduling and distributing device includes but is not limited to the following methods:

[0234] a. The propulsion unit of the hooking device locks the front side of the sample rack to be scheduled, uses the front side of the sample rack to be scheduled as a positioning point, and drives the sample rack to be scheduled to move to the carrying track;

[0235] b. The propulsion unit of the hooking device locks the rear side of the sample rack to be scheduled, uses the rear side of the sample rack to be scheduled as a positioning point, and drives the sample rack to be scheduled to move to the carrying track;

[0236] c. The propulsion unit of the hooking device locks the side edges of the front and rear ends of the sample rack to be scheduled, and uses the side edges of the front and rear ends of the sample rack to be scheduled as positioning points to drive the sample rack to be scheduled to move to the carrying track;

[0237] d. The propulsion unit of the hooking device locks the rear end of the sample rack to be scheduled, uses the rear end of the sample rack to be scheduled as the propulsion point, and pushes the sample rack to be scheduled to move to the carrying track;

[0238] The method in which the propulsion part of the hooking device locks the sample rack to be scanned can be: the propulsion part is set as a hooking hand, and the hooking position on the sample rack to be scheduled cooperates with the hooking hand to achieve linkage.

[0239] The sample rack is transferred to the scheduling and distributing device via the sample rack injection displacement. For the sample rack in the track area entering the scheduling and distributing device, the return track or the sample rack pushing device is controlled to push the sample rack onto the scheduling and distributing device.

[0240] In one embodiment, if Figure 13 As shown, step S104 moves the sample rack to the target position via the scheduling and distributing device, including the process of injecting samples from the conventional injection position to the sample buffer position or the sample output position of the recycling channel, specifically the process of steps S1301-S1308:

[0241] S1301, if the sample rack sample loading position of the sample rack is a regular sample loading position;

[0242] S1302, controlling the scheduling distribution device to move from the last action stop position to the regular sample introduction position;

[0243] S1303, transferring the sample rack to the scheduling and distributing device via the scheduling and distributing device, and performing a scanning operation on the sample rack during the transfer process to obtain sample test information;

[0244] S1304: Determine whether to dispatch the sample rack to the analysis unit based on the sample test information and the occupancy of the track sample aspiration position. If yes, proceed to step S1305; otherwise, jump to step S1306;

[0245] S1305: If the sample rack is an emergency sample rack to be dispatched, the dispatching and distributing device moves the sample rack to the emergency track sample output position; if the sample rack is a regular sample rack to be dispatched, the dispatching and distributing device moves the sample rack to the regular track sample output position;

[0246] S1306: Determine whether the sample rack is transferred to the sample buffer. If yes, proceed to step S1307; otherwise, jump to step S1308.

[0247] S1307, moving the sample rack to an idle sample buffer position in the sample buffer;

[0248] S1308. Move the sample rack to the sample outlet position of the recovery channel.

[0249] In one embodiment, if Figure 14 As shown, step S104 moves the sample rack to the target position via the scheduling and distributing device, and also includes the process of injecting samples from the emergency sample input position to the emergency track sample output position, the conventional track sample output position, or the recycling channel sample output position, specifically the process of steps S1401-S1408:

[0250] S1401, if the sample rack sample loading position of the sample rack is the emergency sample loading position;

[0251] S1402, controlling the dispatching distribution device to move from the last action stop position to the emergency sample introduction position;

[0252] S1403, transferring the sample rack to the scheduling and distributing device via the scheduling and distributing device, and performing a scanning operation on the sample rack during the picking process to obtain sample test information;

[0253] S1404: Determine whether to dispatch the sample rack to the analysis unit based on the sample test information and the occupancy of the track sample aspiration position; if yes, proceed to step S1405; if not, jump to step S1406;

[0254] S1405: If the sample rack is an emergency sample rack to be dispatched, the dispatching and distributing device moves the sample rack to the emergency track sample output position; if the sample rack is a regular sample rack to be dispatched, the dispatching and distributing device moves the sample rack to the regular track sample output position;

[0255] S1406, determine whether the sample rack is transferred to the sample buffer; if so, proceed to step S1407, if not, jump to step S1408;

[0256] S1407, moving the sample rack to an idle sample buffer position in the sample buffer;

[0257] S1408. Move the sample rack to the sample outlet position of the recovery channel.

[0258] In one embodiment, if Figure 15 As shown, step S104 moves the sample rack to the target position via the scheduling and distribution device, and also includes the process of feeding the sample from the sample buffer position to the emergency track sample position, the conventional track sample position, or the recycling channel sample position, specifically the process of steps S1501-S1506:

[0259] S1501, if the sample rack sample loading position of the sample rack is the sample buffer position;

[0260] S1502, controlling the scheduling distribution device to move from the last action stop position to the sample buffer position;

[0261] S1503, transferring the sample rack to the scheduling and distributing device via the scheduling and distributing device;

[0262] S1504: Determine whether the sample rack is dispatched to the analysis unit. If yes, proceed to step S1505; if not, jump to step S1506.

[0263] S1505: If the sample rack is an emergency sample rack to be dispatched, the dispatching and distributing device moves the sample rack to the emergency track sample output position; if the sample rack is a regular sample rack to be dispatched, the dispatching and distributing device moves the sample rack to the regular track sample output position;

[0264] S1506. The sample rack is transferred to the sample output position of the recovery channel via the scheduling and distributing device.

[0265] In one embodiment, if Figure 16 As shown, step S104 moves the sample rack to the target position via the scheduling and distributing device, and also includes the process of returning the channel sample input position to the sample buffer position or the recycling channel sample output position, specifically the process of steps S1601-S1606:

[0266] S1601: If the sample rack sampling position of the sample rack is the return channel sampling position;
