AI Technical Summary
Existing pathogenic microorganism sample transportation systems have difficulty determining whether unpacking, inventory, and signing were completed at the same site. This can lead to unpacking, inventory, or signing in different locations potentially entering the normal performance process, increasing scenario maintenance costs and hindering the handling of anomalies and the archiving of evidence chains.
By linking the unpacking location record, inventory location record, and receipt location record through the handover record module, and combining the location error to form the handover separation quantity, a handover location separation warning is generated, and the transportation service order is controlled not to automatically generate a delivery completion certificate, so as to ensure that the three physical actions of unpacking, inventory and receipt are synchronized.
The system can identify risks of remote unpacking, remote inventory, or remote signing, reduce manual fencing and fixed-distance configuration, improve the reliability of transport box status tracking and order fulfillment process, and ensure the accuracy of delivery completion certificates and the linkage of the evidence chain.

Abstract
Description
Technical Field
[0001] This invention relates to the field of transportation supervision technology, and more specifically, to a full-chain supervision and early warning system for the transportation of pathogenic microorganism samples. Background Technology
[0002] The transportation of pathogenic microorganism samples typically relies on the collaborative efforts of transport containers, container lid detection, positioning terminals, RFID readers, signing terminals, and a monitoring platform. Existing systems can record sample labels, transport container labels, container temperature, container humidity, transport container location, container lid status, communication status, battery level, and electronic signing results around the transport service order, and handle in-transit anomalies such as excessive temperature, excessive humidity, loss of contact, opening, and delayed arrival. In actual operation, opening, inventory, and signing are often recorded on the platform by different terminals at different times. The platform typically only verifies the completeness of label quantity, status records, and signing results. If the opening location record, inventory location record, and signing location record lack a shared verification at the same handover node, the system struggles to determine whether the opening, inventory, and signing were completed at the same location. Even with consistent sample quantities and electronic signing, remote opening, remote inventory, or remote signing may still proceed as normal. For regulatory platforms, relying solely on manual fencing, fixed-distance configuration, or post-event log verification will increase the cost of scenario maintenance and will not be conducive to linking anomaly handling, delivery completion certificates, and evidence chain archiving. Summary of the Invention
[0003] This invention provides a whole-chain monitoring and early warning system for the transportation of pathogenic microorganism samples, which solves the technical problems mentioned in the background art.
[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solution.
[0005] A whole-chain monitoring and early warning system for the transportation of pathogenic microorganism samples, including a handover record module, a handover co-location verification module, and a performance control module; The handover record module associates the unpacking location record, inventory location record, and receipt location record of the same handover node with the transportation service order number. The unpacking location record includes the unpacking coordinates and unpacking location error, the inventory location record includes the inventory coordinates and inventory location error, and the receipt location record includes the receipt coordinates and receipt location error. The handover alignment verification module forms a positional dispersion degree based on the unpacking coordinates, inventory coordinates, and signing coordinates to characterize the dispersion of the unpacking coordinates, inventory coordinates, and signing coordinates relative to the same handover node. It also forms a positioning error benchmark to offset the influence of positioning errors based on the unpacking positioning error, inventory positioning error, and signing positioning error. The positional dispersion degree is then offset using the positioning error benchmark to obtain a non-negative handover separation quantity that characterizes whether the three physical actions of unpacking, inventory, and signing are aligned. When the handover separation quantity indicates that the three physical actions of unpacking, inventory counting, and signing for receipt are not aligned, the performance control module generates a handover separation warning and controls the transportation service order not to automatically generate a delivery completion certificate.
[0006] Compared with the prior art, the present invention has the following substantial features and significant progress: This invention integrates the location records generated from unpacking the transport container, inventorying the samples, and electronic signing into the same transport service order for processing. It also generates a handover separation quantity based on the positioning errors provided by each terminal, enabling the system to identify risks of unpacking, inventorying, or signing remotely when the number of samples is consistent and electronic signing is completed. At the same time, the system links the handover location separation warning with the abnormal pending processing, evidence chain solidification, and delivery completion certificate generation, reducing reliance on manual fencing and fixed distance configurations. This makes it easier for supervisory personnel to trace the status of transport containers, sample handover, and order fulfillment process. Attached Figure Description
[0007] Figure 1 This is a system architecture diagram of a pathogenic microorganism sample transportation end-to-end monitoring and early warning system according to the present invention. Detailed Implementation
[0008] The following description is provided in conjunction with the accompanying drawings. It should be understood that the following embodiments are for illustrative purposes only and are not intended to limit the invention; those skilled in the art can make equivalent substitutions or combinations for the specific implementations.
[0009] The Pathogenic Microorganism Sample Transportation Full-Chain Monitoring and Early Warning System 100 is used to process the entire process of pathogenic microorganism sample transportation service orders, from creation, tag binding, in-transit status collection, routine transportation anomaly judgment, handover record, handover co-location verification, performance control, arrival and receipt, and archiving query.
[0010] like Figure 1 As shown, the pathogenic microorganism sample transportation end-to-end monitoring and early warning system 100 includes an order and label binding module 110, an in-transit status acquisition module 120, a routine anomaly early warning module 130, a handover record module 140, a handover co-location verification module 150, and a performance control and archiving module 160.
[0011] In one implementation, the order management module generates a transportation service order number and records the planned arrival time, transportation storage conditions, and sample quantity. The label binding module reads all sample label numbers in batches before packing to obtain the initial sample quantity, establishes a correspondence between the transportation service order number, the shipping container label number, and the sample label number, and generates an electronic packing list based on the initial sample quantity and sample label numbers. The in-transit status acquisition module collects data on the container's internal temperature, internal humidity, shipping container location, container lid status, and battery level according to the sampling time, and writes the transportation service order number, shipping container label number, and sampling time into the same status record. The routine anomaly warning module generates routine transportation anomalies based on the container's internal temperature, internal humidity, shipping container location sequence, container lid status, communication status, battery level, and planned arrival time.
[0012] At handover nodes requiring unpacking and inventory checks, the handover record module associates the unpacking location record, inventory location record, and receipt location record for the same handover node with the transportation service order number. The unpacking location record includes unpacking coordinates and unpacking location error; the inventory location record includes inventory coordinates and inventory location error; and the receipt location record includes receipt coordinates and receipt location error. The handover alignment verification module calculates the positional dispersion based on the unpacking coordinates, inventory coordinates, and receipt coordinates, and establishes a positioning error benchmark based on the unpacking location error, inventory location error, and receipt location error. The positioning error benchmark is then used to offset the positional dispersion, resulting in a non-negative handover separation amount. When the handover separation amount indicates that the three physical actions of unpacking, inventory, and receipt are not aligned, the performance control module generates a handover positional separation warning and prevents the transportation service order from automatically generating a delivery completion certificate.
[0013] It should be noted that this implementation uses the transportation service order number as a common index for the entire supply chain. When the handover record module processes handover nodes requiring unpacking and inventory checks, it binds and stores the transportation service order number, shipping container label number, handover time, and unpacking location record, inventory location record, and receipt location record for the same handover node. This binding and storage can be implemented jointly by the order database, handover event database, and equipment status database of the monitoring platform, or it can be implemented by a unified data table structure. Regardless of which conventional database implementation method is used, it should be ensured that the three location records of the same handover node are used as inputs for the same unpacking and handover in the subsequent handover co-location verification module.
[0014] Furthermore, the implementation methods for the order management module and the tag binding module are as follows: The order management module receives pathogen sample transportation service requests submitted by sampling institutions and generates a transportation service order number. The transportation service order number is a unique index for each transportation service task and can be a string generated by the regulatory platform based on time, institution code, and serial number, or a unique code generated by the database. The planned arrival time recorded by the order management module is used for routine transportation anomaly detection; the recorded transportation storage conditions are used for comparing the internal temperature and humidity of the container; and the recorded sample quantity is used for sample consistency verification. To avoid the same transportation service order number corresponding to multiple transportation tasks, the order management module writes the transportation service order number into the order basic information after generating it and prohibits assigning the same transportation service order number to other transportation service tasks before the current transportation service order is closed.
[0015] The shipping and storage conditions recorded in the order management module are derived from existing device-readable information in the sample containers, storage media, or consignment documents. These conditions may include a minimum storage temperature, a maximum storage temperature, and the permissible humidity range within the container. The minimum storage temperature can be expressed as... The maximum storage temperature can be expressed as When the transport and storage conditions already include the allowable humidity range inside the box, the routine anomaly warning module compares the humidity inside the box accordingly. When the transport and storage conditions do not include the allowable humidity range inside the box, the routine anomaly warning module does not use the missing allowable humidity range inside the box as the calculation input for the handover and separation quantity, but instead saves the missing state as auxiliary information for routine transport anomaly judgment.
[0016] The tag binding module reads all sample tag numbers in batches before packing to obtain the initial sample quantity. Sample tag numbers can be provided by RFID tags or 2D barcodes, while shipping box tag numbers can be provided by machine-readable tags on the shipping boxes. When reading sample tag numbers, the tag binding module intercepts duplicate reads, read failures, and discrepancies in read quantities. After verifying the read results, it establishes a correspondence between the transportation service order number, shipping box tag number, and sample tag number, and generates an electronic packing list based on the initial sample quantity and sample tag numbers. The electronic packing list includes at least the transportation service order number, shipping box tag number, sample tag number, initial sample quantity, read time, and reading terminal identifier.
[0017] The order management module maintains the status of transportation service orders. The status of a transportation service order can include: Pending Pickup, In Transit, Pending Exception, Pending Verification of Receipt, Delivered, or Closed. The initial status of a transportation service order is Pending Pickup; after pickup and handover verification is successful, the transportation service order is updated to In Transit; if a regular transportation exception or handover location separation warning is not closed, the transportation service order is updated to Pending Exception; if the handover separation value at any handover node requiring unpacking and inventory indicates that the three physical actions of unpacking, inventory, and signing are not synchronized, the transportation service order remains Pending Verification of Receipt until it reaches the signing stage; when the comparison results are consistent, all regular transportation exceptions have been closed, and the handover separation value at each handover node requiring unpacking and inventory indicates that the three physical actions of unpacking, inventory, and signing are synchronized, the transportation service order is updated to Delivered.
[0018] Furthermore, the implementation methods of the in-transit status acquisition module and the regular anomaly early warning module are as follows: The on-the-go status acquisition module 120 is used to collect data on the internal temperature, internal humidity, location of the transport box, lid status, and battery level according to the sampling time, and writes the transport service order number, transport box tag number, and sampling time into the same status record. The sampling time can be represented as... ,in This indicates the order in which the status data was collected. The internal temperature of the chamber in the status record can be expressed as... The humidity inside the box can be expressed as The location of the shipping container can be represented as The state of the box lid can be represented as Battery capacity can be expressed as .
[0019] The in-transit status acquisition module generates a transport container location sequence based on sampling time. This sequence consists of transport container locations sorted by sampling time under the same transport service order number and transport container label number. When communication is available, the in-transit status acquisition module uploads status records to the monitoring platform; when communication is unavailable, the module locally stores status records in sampling time order and re-uploads records once communication is restored. During re-upload, the monitoring platform deduplicates and sorts the status records according to the transport service order number, transport container label number, and sampling time to generate continuous records of container internal temperature, humidity, transport container location sequence, lid status, and battery level.
[0020] The routine anomaly warning module 130 generates routine transportation anomalies based on the internal temperature and humidity of the container, the container's location sequence, the container lid status, communication status, battery level, and planned arrival time. Routine transportation anomalies include any of the following: internal temperature or humidity exceeding transportation and storage conditions; opening the container outside of the handover period; the container's location not updating for an extended period; the container's location sequence being interrupted; communication status remaining unavailable; insufficient battery power; and failure to be signed for after the planned arrival time.
[0021] If the temperature inside the container exceeds the transport and storage conditions, this can be determined by comparing the temperature inside the container with the minimum and maximum storage temperatures.
[0022] ; In the above formula, Indicates sampling time The temperature inside the chamber at that time This indicates the minimum storage temperature required during transport and storage. When... Upon establishment, the routine anomaly warning module generates routine transportation anomalies corresponding to the temperature inside the box exceeding the transportation and storage conditions.
[0023] ; In the above formula, Indicates sampling time The temperature inside the chamber at that time This indicates the maximum storage temperature under transport and storage conditions. When... Upon establishment, the routine anomaly warning module generates routine transportation anomalies corresponding to the temperature inside the box exceeding the transportation and storage conditions.
[0024] Opening of containers outside of handover periods is determined by the container lid status and the handover time recorded in the handover record module. If the container lid status shows that the lid has changed from closed to open, but the corresponding sampling time does not fall within the handover time range of the transfer point, carrier personnel change point, or pre-receive handover point being processed by the handover record module, then the routine anomaly warning module generates a routine transportation anomaly corresponding to the opening of containers outside of handover periods. A prolonged period without updates to the container location can be determined by the sampling time interval between adjacent container locations. An interruption in the container location sequence can be determined by the absence of container locations with consecutive sampling times in the container location sequence. A persistently unavailable communication status can be determined by the communication status recorded in the continuous status log.
[0025] The determination of a prolonged delay in container location updates is based on both the container location in the status record and the sampling time. Under the same transportation service order number and container tag number, the routine anomaly warning module reads the status records in ascending order of sampling time. If, after the last status record containing a valid container location, no new valid container location is found in any consecutive status records, and the corresponding sampling time span reaches the location update determination duration, the routine anomaly warning module generates a routine transportation anomaly corresponding to the prolonged delay in container location updates. The location update determination duration is written into the operation and maintenance parameters by the monitoring platform according to the sampling cycle of the container monitoring terminal before the transportation service order enters the transportation in progress state, and remains unchanged during the execution of the same transportation service order.
[0026] An interruption in the shipping container location sequence is determined by the adjacent valid shipping container location records within the sequence. Under the same transportation service order number and the same shipping container tag number, if the number of missing status records between the sampling times corresponding to two adjacent valid shipping container locations reaches the required number of missing records for location sequence interruption determination, or if the sampling time interval between two adjacent valid shipping container locations reaches the required duration for location sequence interruption determination, the routine anomaly warning module generates a routine transportation anomaly corresponding to the shipping container location sequence interruption. The required number of missing records and the required duration for location sequence interruption determination are pre-written into the operation and maintenance parameters by the monitoring platform based on the sampling cycle and transportation monitoring requirements of the transportation service order, and are directly read during the determination process.
[0027] A persistent communication unavailability status is determined by both the communication status in the continuous status record and the sampling time. Under the same transportation service order number and the same shipping container label number, if the communication status changes from available to unavailable and remains unavailable in the continuous status record, and the time span from the first recorded sampling time of unavailable communication status to the current sampling time reaches the communication unavailability determination duration, then the regular anomaly warning module generates a regular transportation anomaly corresponding to the persistent communication unavailability status. The communication unavailability determination duration is written into the operation and maintenance parameters by the monitoring platform before the transportation service order is started; when the communication status recovers to available, the regular anomaly warning module uses the first status record after recovery as the end record.
[0028] Low battery power is determined by comparing the battery level with a low battery power threshold. The low battery power threshold is derived from the equipment manual of the transport container monitoring terminal or the operation and maintenance parameters of the monitoring platform, and is associated with and saved with the transport container tag number before the transport service order enters the "in transit" status. When the routine anomaly warning module reads that the battery level is less than or equal to the low battery power threshold at any sampling time, it generates a routine transport anomaly corresponding to low battery power. If the battery level cannot be read, this status record is simultaneously saved as a battery power shortage record, and is solidified by the evidence chain solidification module when a routine transport anomaly occurs.
[0029] If the delivery has not been signed for by the scheduled arrival time, the regular anomaly warning module will compare the current system time with the scheduled arrival time and determine the delivery completion status by checking whether the arrival and signing module has generated a delivery completion certificate.
[0030] Furthermore, the implementation method of the handover record module is as follows: The handover record module 140 is used to read the transportation service order number and the shipping container label number at transit points, carrier personnel change points, or pre-receive handover points. The handover record module generates a handover record between the handover terminal and the receiving terminal, and saves the handover terminal, the receiving terminal, and the handover time. The handover time may include the time the handover is initiated by the handover party, the time the receiving party confirms receipt, and the time the system saves the handover record; when using three location records associated with the same handover node, the handover time range of the same handover node shall prevail.
[0031] When an inventory check is required, the handover record module saves an unpacking location record when the box lid changes from closed to open, an inventory location record when the batch reading of sample labels is completed, and a receipt location record when acceptance is confirmed. The unpacking location record comes from the transport box positioning terminal, the inventory location record comes from the inventory terminal that completed the batch reading of sample labels, and the receipt location record comes from the receiving terminal. All three location records include planar coordinates and positioning errors, where the positioning error is the horizontal positioning error directly reported by the corresponding terminal.
[0032] No. In the handover node where an unpacking and inventory check is required, the unpacking location record is shown as follows: .in, and These are the two planar coordinate components of the box opening coordinates. This is an error related to the opening and positioning of the container. The opening and positioning record is saved when the container lid changes from closed to open, and the recording time corresponds to the actual physical action of the container being opened.
[0033] At the same handover point, the inventory location record is represented as .in, and These are the two planar coordinate components of the inventory coordinates. This is an inventory location error. The inventory location record is saved when the sample tags are read in batches, and the time of recording corresponds to the entity action in which the sample tag numbers are read in batches.
[0034] Within the same handover node, the signature and location record is represented as .in, and These are the two planar coordinate components of the receipt coordinates. This is a delivery confirmation error. The delivery confirmation record is saved when receipt is confirmed, and the recording time corresponds to the physical action of the receiving terminal confirming receipt.
[0035] If the terminal directly outputs latitude and longitude coordinates, the handover record module or monitoring platform will convert these coordinates into the same local plane coordinates before saving the unpacking coordinates, inventory coordinates, and receipt coordinates. This conversion can use the local projection processing method commonly provided by the positioning service, ensuring that the unpacking coordinates, inventory coordinates, and receipt coordinates are located in the same plane coordinate system, with the unit being meters. This processing is only used to enable the handover verification module to calculate the spatial dispersion of the same handover node.
[0036] The handover record module compares the currently read sample tag number and sample quantity with the sample tag number and sample quantity saved at the previous handover node. If the comparison results match, the handover record module saves the current handover record; if the comparison results do not match, the handover record module still saves the already generated unpacking location record, inventory location record, and receipt location record, and outputs the comparison results to the performance control module and the evidence chain solidification module, enabling the transportation service order to enter the abnormal pending processing or receipt pending verification state. For handover nodes that only undergo closed transit and have not undergone unpacking and inventory, the handover record module continues to use the sealed box handover record method.
[0037] To ensure that the three location records belong to the same handover node, the handover record module generates or reads a handover node identifier when it begins processing the handover node. This identifier is then stored together with the transportation service order number, container label number, handover time, unpacking location record, inventory location record, and receipt location record. The handover node identifier is only used for binding routine event data. If a separate handover node identifier is not used, the system can also determine the same handover node using the transportation service order number, container label number, handover time range, and the sender's and receiver's terminals.
[0038] When no separate handover node identifier is used, the start point of the handover time range is the sampling time when the handover terminal reads the transportation service order number and the shipping container label number at the transfer point, carrier personnel change point, or pre-receive handover point and initiates the sampling process requiring unpacking and inventory checking. The end point of the handover time range is the later of the receipt location record retention time and the system's handover record retention time. If the duration from the start point to the end point exceeds the handover duration determination period, the handover record module will not directly identify the unpacking location record, inventory location record, and receipt location record within that time range as the same handover node, but will output that handover node as receipt pending verification. The handover duration determination period is written into the operation and maintenance parameters by the regulatory platform before the transportation service order enters the transportation status and remains unchanged during the execution of the same transportation service order.
[0039] When multiple unpacking and inventory checks occur under the same transportation service order number and the same shipping container label number, the handover record module sorts the unpacking location records, inventory location records, and receipt location records from earliest to latest according to the handover time. Each unpacking location record can only form the same handover node with the first unassigned inventory location record after it and the first unassigned receipt location record after it; an unpacking location record, inventory location record, or receipt location record that has already been assigned to a handover node cannot be reassigned to other handover nodes. If any type of location record is missing, or if the sorting relationship does not meet the chronological order of unpacking location records, inventory location records, and receipt location records, the handover record module will not generate the handover separation quantity for that handover node and will output the existing records to the evidence chain solidification module.
[0040] Furthermore, the implementation method of the handover peer verification module includes: The handover verification module 150 receives the unpacking location record, inventory location record, and receipt location record output by the handover record module 140, and determines the handover center point based on the unpacking coordinates, inventory coordinates, and receipt coordinates. The handover center point represents the planar position center of the three physical actions of unpacking, inventory, and receipt within the same handover node. The handover center point can be represented as... The calculation method is as follows.
[0041] ; In the above formula, Indicates the first The handover center point of the handover node that requires unpacking and inventory checking. Indicates the coordinates of the unpacking. Indicates the coordinates of the inventory count. The coordinates indicate the points of receipt. The handover center point is formed by the arithmetic mean of the three coordinates of the same handover node.
[0042] The handover verification module determines the degree of positional dispersion based on the differences between the unpacking coordinates, inventory coordinates, and receipt coordinates relative to the handover center point. To determine this dispersion, the module calculates the unpacking distance, inventory distance, and receipt distance separately. The unpacking distance represents the distance from the unpacking coordinates to the handover center point; the inventory distance represents the distance from the inventory coordinates to the handover center point; and the receipt distance represents the distance from the receipt coordinates to the handover center point.
[0043] ; In the above formula, Indicates the distance from the box opening. Indicates the coordinates of the unpacking. Indicates the center point of the handover.
[0044] ; In the above formula, Indicates the distance of the inventory check. Indicates the coordinates of the inventory count. Indicates the center point of the handover.
[0045] ; In the above formula, Indicates the distance to the delivery receipt. Indicates the delivery coordinates. Indicates the center point of the handover.
[0046] In one implementation, the degree of location dispersion is expressed as The distance is calculated from the root mean square of the distance between the unpacking, inventory, and signing. Using this method, if any physical action during unpacking, inventory, or signing deviates significantly from the handover center point, the positional dispersion will increase, thus avoiding misjudgments caused by comparing only two coordinates and overlooking the third.
[0047] ; In the above formula, Indicates the degree of location dispersion. Indicates the distance from the box opening. Indicates the distance of the inventory check. This indicates the distance to the delivery confirmation. The dimension of the location dispersion is length, and the unit is consistent with the plane coordinate system where the unpacking coordinates, inventory coordinates, and delivery coordinates are located.
[0048] The handover verification module establishes a positioning error benchmark based on the positioning errors from unpacking, inventory, and signing for receipt. This benchmark is used to offset the impact of positioning errors and originates from the horizontal positioning errors directly reported by the corresponding terminals in the unpacking, inventory, and signing for receipt records, rather than from artificial geofencing or manually set fixed distances. The positioning error benchmark can be expressed as... The calculation method is as follows.
[0049] ; In the above formula, Indicates the positioning error reference. This indicates the error in unpacking and positioning. This indicates the inventory location error. This indicates the location error during acceptance. The location error benchmark is formed by averaging the three location errors and is used to reflect the location uncertainty jointly reported by the three location records at the same handover node.
[0050] The handover and alignment verification module then uses the positioning error benchmark to compensate for the position dispersion. This compensation process first generates a handover and alignment margin, which represents the portion of the position dispersion that exceeds the positioning error benchmark. The handover and alignment margin can be expressed as... The calculation method is as follows.
[0051] ; In the above formula, This indicates the remaining balance after handover and acceptance. Indicates the degree of location dispersion. This represents the positioning error baseline. The handover and receipt margin can be positive, zero, or negative. When the handover and receipt margin is not greater than zero, it indicates that the existing positioning data cannot prove that the three physical actions of unpacking, inventory, and signing for receipt exceed the influence of positioning error and cause position separation.
[0052] The handover and verification module obtains the non-negative handover separation quantity based on the handover and acceptance margin. The handover separation quantity is expressed as... The calculation method is as follows.
[0053] ; In the above formula, Indicates the amount of separation at the transfer point. This indicates the remaining balance after handover and acceptance. Indicates taking and The larger values in the middle. Therefore, the crossover separation quantity is a non-negative quantity. When At that time, the handover separation quantity indicates that the three physical actions of unpacking, inventory counting, and signing for receipt are completed simultaneously; when At that time, the separation of the handover indicates that the three physical actions of unpacking, inventory, and signing for receipt were not completed in the same manner.
[0054] When any three location records are missing, or any location error is missing, the handover verification module does not use the missing data to generate a handover separation quantity. Instead, it outputs the handover node as a state where handover verification cannot be completed. This state is used by the performance control module as a condition for the transportation service order not to automatically generate a delivery completion certificate, and the evidence chain solidification module solidifies the existing unpacking location record, inventory location record, receipt location record, handover terminal, receiving terminal, and handover time. This process is used to prevent missing data from being mistakenly identified as equivalent receipt.
[0055] Furthermore, the implementation methods of the performance control module, evidence chain solidification module, arrival and receipt module, and archive query module are as follows: The fulfillment control module receives the handover separation quantity output by the handover alignment verification module and controls whether the transportation service order automatically generates a delivery completion certificate based on the handover separation quantity. When the handover separation quantity indicates that the three physical actions of unpacking, inventory counting, and signing are not aligned, the fulfillment control module generates a handover location separation warning and prevents the transportation service order from automatically generating a delivery completion certificate. The handover location separation warning records at least the transportation service order number, the shipping container label number, the handover node where the handover location separation warning occurred, the unpacking location record, the inventory counting location record, the signing location record, the location dispersion, the location error benchmark, and the handover separation quantity.
[0056] When the fulfillment control module receives a routine transportation anomaly, it also controls the transportation service order to enter the anomaly pending processing state. Routine transportation anomalies and handover location separation warnings handle different issues: routine transportation anomalies are used to indicate problems related to the transportation process, such as container temperature, container humidity, container location sequence, container lid status, communication status, battery level, or planned arrival time; handover location separation warnings are used to indicate that the three physical actions of opening, inventory, and signing for receipt at the same handover node are not synchronized. Both can prevent the automatic generation of delivery completion certificates for the transportation service order, but the generation of the handover location separation warning is based on the amount of handover separation.
[0057] When the evidence chain solidification module receives a warning about a routine transportation anomaly or a separation of handover locations, it marks the corresponding transportation service order as an anomaly pending processing and solidifies the following data before and after the anomaly: container temperature, container humidity, container location, container lid status, electronic packing list, communication status, battery level, unpacking location record, inventory location record, receipt location record, handover terminal, receiving terminal, and handover time. Solidification can be achieved through conventional methods such as writing to append-only logs, generating hash checksums, setting an overwriteable flag for database records, or synchronizing to the regulatory platform's archive. Its purpose is to preserve the generated performance documents and original records, facilitating subsequent verification of handover location separation warnings.
[0058] Upon arrival at the receiving laboratory, the arrival and receipt module reads the transportation service order number, the transportation box label number, and all sample label numbers to obtain the number of arriving samples. It then compares this number with the sample label numbers read upon arrival against the electronic packing list and the sample label numbers and quantities saved at the previous handover node. If the comparison results match, it means the sample label numbers and number of arriving samples match the data in the electronic packing list and the data saved at the previous handover node. If the comparison results do not match, the arrival and receipt module does not generate a delivery completion certificate and outputs the comparison result to the performance control module.
[0059] For the comparison results to be consistent, both the quantity consistency condition and the label consistency condition must be met simultaneously. The quantity consistency condition is: the number of arriving samples equals the initial number of samples in the electronic packing list, and if a previous handover node exists, the number of arriving samples equals the number of samples saved in that previous handover node. The label consistency condition is: the set of sample label numbers read upon arrival is exactly the same as the set of sample label numbers in the electronic packing list, and if a previous handover node exists, the set of sample label numbers read upon arrival is exactly the same as the set of sample label numbers saved in that previous handover node. If no intermediate handover record occurred for the transportation service order, the arrival and receipt module uses the electronic packing list as the substitute comparison object for the data saved in the previous handover node.
[0060] Before generating a comparison result, the arrival and receipt module first checks for duplicate labels on the sample label numbers read upon arrival. If there are duplicate labels among the sample label numbers read upon arrival, or if there are sample label numbers not included in the electronic packing list, or if there are missing sample label numbers already included in the electronic packing list, or if the sample label numbers are not completely identical to those saved at the previous handover node, then the comparison result is inconsistent. When the comparison result is inconsistent, the arrival and receipt module does not generate a delivery completion certificate, and outputs the number of arrived samples, the sample label numbers read upon arrival, the electronic packing list, and the sample label numbers and sample quantities saved at the previous handover node to the performance control module and the evidence chain solidification module.
[0061] The arrival and receipt module also downloads data on the container's internal temperature, humidity, location sequence, lid status, routine transportation anomalies, handover location separation warnings, and the separation amount at each handover node requiring opening and inventory checks. When the comparison results are consistent, all routine transportation anomalies are closed, and the separation amount at each handover node requiring opening and inventory checks indicates that the opening, inventory check, and receipt actions are synchronized, the arrival and receipt module generates a delivery completion certificate. If the separation amount at any handover node requiring opening and inventory checks indicates that the opening, inventory check, and receipt actions are not synchronized, the arrival and receipt module does not generate a delivery completion certificate; instead, the transportation service order remains signed but awaiting verification.
[0062] The archive query module archives basic order information according to the transportation service order number, the correspondence between the transportation service order number and the shipping container label number, the correspondence between the transportation service order number and the sample label number, the electronic packing list, pickup handover records, intermediate handover records, container temperature, container humidity, shipping container location sequence, opening and positioning records, routine transportation anomalies, handover location separation warnings, anomaly handling records, and electronic signature records. Based on the archived content, it generates a full-link report for tracing handover location separation warnings. The full-link report is organized around the transportation service order number and does not evaluate the medical quality of the sample; it only describes the fulfillment process of the transportation service order from pickup, in-transit monitoring, handover verification, arrival signature to archive query.
[0063] As an optional implementation, after the sampling agency creates a transportation service order, the label binding module reads all sample label numbers and generates an electronic packing list. The in-transit status acquisition module continuously uploads status records according to the sampling time, and the routine anomaly warning module does not generate routine transportation anomalies. When the transport box needs to be opened and inventoried at the handover point before receipt, the handover record module sequentially saves the opening location record, inventory location record, and receipt location record. The opening coordinates, inventory coordinates, and receipt coordinates in the three location records are all located at the same handover site, and the opening location error, inventory location error, and receipt location error in the three location records can cover the visible dispersion of the three coordinates. At this time, the handover separation amount calculated by the handover co-location verification module is... The performance control module does not generate a handover location separation warning; the arrival and receipt module generates a delivery completion certificate according to the aforementioned receipt verification rules.
[0064] As an optional implementation, the transport container is opened at a transit point, the inventory terminal completes batch reading of sample labels at another location, and the receiving terminal confirms receipt at different locations. The handover record module still associates and saves the opening location record, inventory location record, and receipt location record under the same handover node using the transport service order number. Because the differences between the opening coordinates, inventory coordinates, and receipt coordinates and the handover center point increase, the positional dispersion formed by the handover co-location verification module is greater than the positioning error benchmark. After offsetting processing, the resulting handover separation is greater than... At this point, the performance control module and the evidence chain solidification module process the order according to the aforementioned performance control rules and solidification rules, respectively, and put the transportation service order into the stage of pending receipt and verification.
[0065] As an optional implementation, the in-transit status acquisition module collects data on the container's internal temperature, humidity, location, lid status, and battery level according to the sampling time. However, due to the unavailability of communication, the status records cannot be uploaded to the monitoring platform in real time. The in-transit status acquisition module stores the status records locally in the order of sampling time and continues to re-transmit the status records after the communication status becomes available again. The routine anomaly warning module can generate routine transportation anomalies based on the continued unavailability of communication, and updates the container location sequence, internal temperature, humidity, lid status, and battery level based on the re-transmitted status records after re-transmission is completed.
[0066] It should be noted that this implementation can be jointly achieved by a monitoring platform server, a transport container monitoring terminal, an inventory terminal, a receiving terminal, and a handover terminal. The monitoring platform server may include a processor, memory, database, and network communication interface. The inventory terminal may include an RFID reader or 2D barcode reader, a positioning unit, a communication unit, and a display and interaction unit. The receiving terminal may include a positioning unit, a communication unit, an identity verification unit, and a receipt confirmation unit. The handover terminal may include a reading unit for reading the transport service order number and transport container label number, a communication unit, and a handover confirmation unit. All of the above terminals can communicate with the monitoring platform via cellular communication, NB-IoT, wireless LAN, or other conventional communication methods. When communication is unavailable, the in-transit status acquisition module and the handover record module can write status records and handover records to local storage, and continue to retransmit status records and handover records after communication is restored to availability.
[0067] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and all such modifications and variations fall within the scope defined by the appended claims.

The unpacking location record includes the unpacking coordinates and unpacking location error, the inventory location record includes the inventory coordinates and inventory location error, and the receipt location record includes the receipt coordinates and receipt location error. The handover alignment verification module forms a positional dispersion degree based on the unpacking coordinates, inventory coordinates, and signing coordinates to characterize the dispersion of the unpacking coordinates, inventory coordinates, and signing coordinates relative to the same handover node. It also forms a positioning error benchmark to offset the influence of positioning errors based on the unpacking positioning error, inventory positioning error, and signing positioning error. The positional dispersion degree is then offset using the positioning error benchmark to obtain a non-negative handover separation quantity that characterizes whether the three physical actions of unpacking, inventory, and signing are aligned.
