Description

Technical Field

[0001] This invention relates to the field of life science research technology, and in particular to a laboratory animal production management system and method based on RFID technology. Background Technology

[0002] With the development of life science technology and people's increasing emphasis on health, the market demand for laboratory animals is increasing, and there is growing concern about the quality of laboratory animals.

[0003] The current production, use, and management of laboratory animals in the industry are mostly done manually, which leads to problems such as low production efficiency, unstable animal quality, heavy workload, and high production and management costs. In particular, laboratory animal production and use facilities are mostly cleanroom barriers, and personnel access is strictly restricted, which increases the difficulty of management and hinders information transmission.

[0004] Existing laboratory animal production management systems on the market are mostly computer systems deployed outside the barrier facility, relying on manual data entry. They lack direct communication with the front-line processes within the barrier, making it difficult to achieve coordination, scheduling, and real-time updates and feedback of information data between different production processes. Some production management systems have added methods for scanning animal tags using handheld mobile devices to establish a link between animals and the management database. However, this method primarily links animals to the animal information management system and does not achieve the collection, transmission, processing, and feedback of data information within the production process. It cannot coordinate the collaboration between different production processes to improve production efficiency and animal quality, or reduce production costs. Furthermore, these handheld terminals cannot locate animals of different strains, ages, or groups, still relying heavily on manual operation. For facilities with an annual production of millions of animals and tens of thousands of cages, the efficiency improvement is very limited.

[0005] In order to meet the growing demand for laboratory animals in the life science research field, reduce the workload of laboratory animal production personnel and researchers, and improve the efficiency and quality of laboratory animal production and use, there is an urgent need to establish an efficient, real-time, dynamic, automated, and intelligent production system to break away from the traditional production model that is highly dependent on manual operation.

[0015] This invention also provides a management method for the experimental animal production management system based on RFID technology, comprising the following steps: sending a target work task to an interactive terminal via a task allocation module; enabling staff belonging to the target work group to claim the task via the interactive terminal, thereby binding the task code and the staff identification code; binding the task code, staff identification code, and target task operation object code via a second type of RFID reader / writer device; the interactive terminal gradually sending guidance information to the staff to enable them to perform work task operations according to the guidance information; the operation information identification and acquisition module capturing the operation execution status information of the staff on the target work task; the information transmission module sending the collected operation execution status information to the task execution review module; the task execution review module comparing and verifying the operation execution status information and the decomposition steps of the SOP; if the consistency review fails, sending a warning message to the interactive terminal; when the staff completes the target work task and the actual operation passes the consistency review, enabling the staff to release the task via the interactive terminal, thereby unbinding the task code, staff identification code, and target task operation object.

[0016] The beneficial effects of this invention are:

[0017] (1) Improved production efficiency: This invention eliminates the traditional method of relying on manual viewing and recording of tasks. Staff can obtain tasks by activating the interactive terminal through identification tags. The work execution status and results are automatically entered into the system database, eliminating the need for manual recording and transmission, thus saving time and effort. This invention breaks through the limitations of traditional fixed-area animal search. The system can accurately track the location of animals and cages, supports the arbitrary placement of cages, and assigns tasks based on the nearest location according to the workflow, reducing the travel distance and time for staff and improving work efficiency.

[0018] (2) Ensuring Animal Quality: This invention provides detailed SOP guidance information through the operation guidance module and real-time review of operations through the task execution review module, standardizing staff operation procedures, effectively reducing human error, avoiding the impact of improper operation on animal health and experimental results, ensuring the reliability of animal experimental data, and improving the quality of experimental animals. This invention utilizes temperature, humidity, and other sensor tags to monitor the environmental parameters of experimental animals in real time. Once the parameters exceed the preset threshold range, the system immediately alarms and automatically adjusts to create a stable living environment for the animals, reducing the interference of environmental factors on animal physiological functions and ensuring the accuracy of experimental data. This invention can utilize passive data acquisition tags such as liquid level sensors and pressure sensors to detect the consumption of drinking water and feed by animals. Once it falls below the preset threshold, the system will issue a prompt to relevant staff to replace or add food to ensure animal welfare and animal health.

[0019] (3) Enhanced Management Efficiency: This invention achieves precise binding and unbinding of tasks, personnel, and operational objects through a unique task code, staff identification code, and target task operation object code system. The system can track task progress in real time, view the executors, operational objects, and execution progress of each task, facilitating management and supervision. When personnel transfers or task adjustments occur, the system can quickly respond to reassign tasks, enhancing the accuracy and traceability of task management. The information recording module comprehensively records the information flow of each link in production management, including task allocation, acceptance, operation execution, and review information, and associates it with time, location, operational object, and operator identity attributes. This rich data provides strong support for production process traceability, problem analysis, and optimization, helping to identify bottlenecks and optimization points in the production process and improve the overall management level. The data collected by the information recording module in this invention can be used as raw data for machine learning and intelligent factory AI algorithms. The automated data collection, transmission, and processing of this invention can reduce manual operation links and lower labor costs. At the same time, it avoids resource waste caused by manual recording errors and chaotic animal information management, further reducing production management costs. Attached Figure Description

Detailed Implementation

[0022] This invention can be applied to the production of various laboratory animals, with its application value particularly evident in the production of rodents. In rodent production, existing technologies cannot coordinate the collaboration between different production processes. Collaboration between different production processes refers to the digital collection, transmission, processing, and feedback of information from each different process within the entire production workflow, rather than simply collecting information from the objects being produced. Digitalization of processes significantly improves the efficiency of communication and collaboration between them. For example, in a production process with five processes, when one process changes, in traditional methods, this change information is transmitted sequentially as the object being produced moves to other processes, making it impossible to transmit change information to the other four process units simultaneously and promptly, hindering timely responses and adjustments. This invention, however, utilizes RFID technology to achieve comprehensive digital management of the production process. In rodent production, each process operates collaboratively through interactive terminals, reader / writer units, various modules, and the system backend. This enables real-time information sharing between production processes. If a change occurs in one process, the system can quickly synchronize the information to other processes, allowing each stage to respond and adjust promptly. For example, in the processes of rodent breeding, feeding, experimental preparation, and experimental operation, changes in animal reproduction can be immediately fed back to subsequent feeding and experimental preparation processes. Staff can adjust feeding plans and experimental arrangements in a timely manner, which greatly improves overall production efficiency and management precision, effectively solving the problems of existing technologies. From the perspective of lean production theory, this represents a shift from the traditional pull production model between processes to a collaborative production model between processes.

[0023] Traditional pull production model, such as Figure 5 As shown, the production process can only control the beginning and end; changes can only be transmitted sequentially between the intermediate processes. The production management model based on the digital technology of this invention is as follows: Figure 6 As shown, when production changes, adjustments can be made simultaneously to each production process.

[0024] like Figure 4 As shown, this invention provides a laboratory animal production management system based on RFID technology, comprising:

[0025] The system includes a task management subsystem, comprising a task allocation module, a task assignment module, a task operation guidance module, a task execution review module, and a task completion module; a staff management subsystem, comprising a staff information collection module; the staff management subsystem is deployed on an interactive terminal, which is located within the target work area for experimental animal production; a work object management subsystem, comprising an operation information identification and collection module; the work object management subsystem is deployed at work points, which are located within the target work area; a data information management subsystem, comprising an information transmission module and an information recording module; and a task allocation module, used to assign target work tasks to target work groups. The target work task is associated with the target task operation object and operation steps; the task claiming module is used to enable staff members belonging to the target work group to claim tasks after identity authentication through any of the interactive terminals; the task operation guidance module is used to send guidance information to the staff members who claim tasks through the interactive terminal; the guidance information includes the SOP for each operation step; the operation information identification and collection module is used to collect the operation execution status information of the target task operation object; the task execution review module is used to review the consistency between the actual operation and the SOP based on the operation execution status information, as a condition for the release of the target work task.

[0026] RFID technology is a technology that uses RFID readers installed at different locations to couple with RFID tags installed on the work object to achieve data collection. In specific implementation, the interactive terminal can include a mobile interactive terminal and a fixed interactive terminal. The mobile interactive terminal can move within the target work area, while the fixed interactive terminal can be fixed at the target work point.

[0027] For mobile interactive terminals, RFID identification technology can be used to bind them to specific staff members. For example, each staff member is equipped with a unique identification tag (based on RFID technology). When a staff member wants to use the mobile interactive terminal, they can activate it with their work tag. The mobile interactive terminal then obtains the staff member's identification information, which serves as the operator's account information to open the mobile interactive terminal.

[0028] For fixed interactive terminals, they can be installed at each specific work point (or workflow point). The production management system backend will assign the daily or immediate work tasks to the corresponding work points and display them on the fixed interactive terminals. Once a worker is bound to a work point and the corresponding fixed interactive terminal, the system will immediately assign the work tasks for that work point to that worker.

[0029] It's important to understand that the interactive terminal is not a necessary module of this system. It can be understood as a limitation of the laboratory animal industry; current technology cannot fully realize unmanned factories, and some tasks and operations still require manual intervention, thus necessitating an auxiliary input / output device. Conversely, sensor data collection, transmission, recording, and processing do not require human intervention, thus eliminating the need for an interactive terminal. As technology advances, the basic architecture of this system will not change, but the interactive terminal will gradually become obsolete. If the interactive terminal serves as a medium for information exchange among staff, then there should also be a corresponding medium for information exchange with the task object; this is the RFID reader / writer unit in this invention.

[0030] For staff, RFID identification technology can be used to bind them to specific work areas and work locations. This involves binding fixed interactive terminals to specific work areas and work locations, and mobile interactive terminals to specific staff members, as well as binding specific staff members to their work areas and work locations. This allows for the allocation of specific work task information to specific work areas, work locations, and specific staff members.

[0031] When the task assignment module is working, it can send target work tasks to specific work areas, work locations, and work teams through fixed interactive terminals or mobile interactive terminals installed inside the facility (or through other more flexible operating devices such as computers or mobile apps located outside the facility). For fixed interactive terminals, their location can be defined by the specific physical address code of the work area or work location to which they belong.

[0032] When the task operation guidance module is working, it can use the interactive terminals located at each work point to send operation guidance information step by step to the staff who have claimed the task after receiving the claim confirmation signal. The system breaks down a task into several operation steps according to the standard operating procedure (SOP). Through the interactive terminal, the SOP of each operation step is displayed to the staff in the form of text, images or sound.

[0033] The first piece of information in the guidance message might be the specific object being manipulated, such as an animal or a cage, including its location. After the staff moves the object to the workbench, an RFID reader installed on the workbench will authenticate the object's identity. If the authentication is successful, the task, personnel, and object are successfully linked, and the guidance message will proceed to the next step.

[0034] Regarding the step-by-step delivery of operation guidance information, a specific operation process may include several operation steps. The specific operation steps and their order are strictly defined by the Standard Operating Procedure (SOP). The system can guide and verify the operation of the staff step by step according to the standard SOP, which is of great help to improve product quality and can minimize the inefficiency and quality problems caused by human factors.

[0035] The system of this invention can capture the signal access and disconnection status of RFID tag transponders associated with operational tasks, as well as the continuous changes in this status, through a group of second-type RFID reader / writer devices bound to the work site, and record each change in the production management system. By capturing the changes in RFID tag status, the production management system can automatically confirm the completion of each operation step and send information to the interactive terminal. The confirmation of each operation step by the production management system can trigger the interactive terminal to output and display guidance information for jumping to the next SOP operation step. The "automatic confirmation" emphasized here means that it is executed automatically by the system without human intervention.

[0036] The connection and disconnection of RFID tags and RFID readers can reflect whether the operated or tracked object is correctly present at a certain operation point, thus preventing errors. Furthermore, the system records when an object connects to which point, when it leaves that point, and how long it takes before it reappears at the next point and completes connection. This information is used to determine if there are errors in the operation sequence, or if the dwell or disconnection time exceeds the standard. This is also a fundamental data source for implementing machine learning and enabling the system to make self-decision.

[0037] For environmentally sensitive animals, leaving the standard living environment provided by the container system may lead to changes in their functions and condition, affecting the quality of animal products. If the time spent at a process point exceeds a reasonable range (threshold), production accidents or efficiency problems may occur. For several operational steps in an operation process, verification is not required; it can be simply understood that the reader capturing the access of a tag is the start, and the tag detachment is the end, with tag detachment being the system's confirmation signal for termination. Determining whether something is "reasonable" requires the system to capture several operational actions in an operation process and comprehensively judge their sequence, intervals, the time consumed by each step, and the overall duration.

[0038] When the operation information identification and acquisition module is working, it can automatically collect information from operational processes and actions in the overall production flow that have information collection value. It defines which "objects" have information collection value. RFID tag transponders can be installed on different target tracking objects. During production operations, these RFID tag transponders couple and transmit signals with RFID reader / writer devices installed at different work points to obtain the location, status, and other relevant information of the target tracking objects. RFID tags can be installed on animals to collect their identification and location information; RFID tags can be installed on animal containers to collect their identification and location status information; RFID tags can be installed on sensors for temperature, humidity, weight, and liquid level to collect their status data and location information. The information collected by the module can be changes in location, changes in status, changes in quantity, combinations of several different changes, or the sequence of several changes. The operation information identification and acquisition module mainly relies on RFID readers / writers and has no direct connection with the interactive terminal.

[0039] When the task execution review module is working, it can transmit the data collected by the operation information identification and collection module to the animal production management system backend through the information transmission module. This data is then compiled into the execution status of a work task or operation step, and compared, judged, and fed back with the pre-determined SOP. It can be used to verify whether the specific content of the executed operation is consistent with the task assigned by the work task allocation module; whether the executor of the task is consistent with the executor confirmed by the task assignment module; and whether the operation of the work task is consistent with the steps of the operation guidance module. If there is an inconsistency in the review results, a warning message can be promptly sent to the interactive terminal associated with the executor, prompting correction. If the review results are correct, the system can automatically proceed to the next process or operation step. In this invention, the main steps directly involving human participation can be limited to task allocation → task assignment → obtaining guidance information → task execution. The review of the task execution results in this invention is completed automatically by the system and interacts with the on-site operation process through the information transmission module.

[0040] In practical implementation, the production management system can establish a standard task breakdown structure. When decomposing tasks level by level to specific work operation steps, each step corresponds to a Standard Operating Procedure (SOP). RFID signal acquisition does not directly link to a specific SOP; it simply records who appeared / left or what numerical value was returned in the database. This value can then serve as input parameters for a discrimination algorithm, allowing the system to perform judgment and calculations.

[0041] Existing laboratory animal production management systems suffer from numerous shortcomings. Most systems have hardware located outside the barrier facility, rely on manual data entry, and lack direct connection with the frontline processes within the barrier. This prevents coordination, scheduling, and real-time updates and feedback between production processes. Even when some systems add the ability to scan animal tags using handheld mobile devices, they merely link animals to the information management system without effectively collecting, transmitting, processing, or providing feedback on production process data. This hinders the coordination of various processes to improve production efficiency and animal quality, and prevents the location of animals of different strains, ages, and populations. They remain highly dependent on manual operation, resulting in limited efficiency improvements in large-scale production scenarios.

[0042] This invention relates to an experimental animal production management system built upon RFID technology, with each module working in close coordination. The task allocation module achieves precise task assignment through accurate equipment and personnel binding; the task assignment module clarifies task ownership; the operation guidance module automatically guides operations according to Standard Operating Procedures (SOPs) and confirms step completion; the operation information identification and collection module comprehensively collects various production process data and captures operational status; the information transmission module ensures accurate data transmission; the task execution review module guarantees that operations comply with standards; the information recording module records information throughout the entire production process; and the task completion module achieves closed-loop management of tasks. These modules work collaboratively to achieve automated and intelligent management of the production process.

[0043] Traditionally, task acquisition relies on manual viewing and recording, animal location locating is limited and time-consuming, animal information tags are inconvenient to fill out and update, and cage replacement is cumbersome. This invention's system allows staff to acquire tasks simply by activating an interactive terminal using an identification tag. The system accurately locates animals and cages, automatically records and updates animal information, significantly simplifying cage replacement, reducing operational steps and search time, and improving overall production efficiency. This system can monitor the environmental parameters of laboratory animals in real time (such as temperature and humidity information collected through sensor tags), promptly detect anomalies, and automatically adjust to reduce the impact of environmental factors on animals. The system can also monitor the consumption of daily animal drinking water, feed, and other major production materials, promptly reminding staff to replenish them. Simultaneously, standardized operating procedures and review mechanisms reduce human error, ensuring the accuracy and reliability of animal experimental data, thereby improving the quality of laboratory animals. Through automated data acquisition, transmission, and processing, manual operations are reduced, labor costs are lowered, and resource waste caused by manual recording errors and chaotic animal information management is reduced, further lowering production management costs.

[0044] The modules in this invention are designed to achieve their respective functions through system integration, combining hardware devices and software systems according to requirements and application scenarios. The hardware requirements of this invention mainly include interactive terminal devices (mobile interactive terminals, fixed interactive terminals, etc.), identity recognition and data acquisition devices (RFID readers, RFID badges, RFID tags, RFID sensors, etc.), network transmission devices (routers, switches, etc.), and system backend devices (servers, database storage devices, etc.). The specific devices used for the interactive terminals can be varied; fixed interactive terminals can be computers, industrial control computers, touchscreen computers, etc., while mobile interactive terminals can be mobile phones, tablets, smartwatches, etc.

[0045] It's important to understand that the term "system" in this invention emphasizes a system process, thus ignoring the physical presence of servers and interactive terminals. However, the physical carrier of the software component, especially applications deployed in the cloud, is highly likely to be a server. The purpose of this system is to track and identify the manipulated objects—"animals, cages, and sensors." By tracking and identifying these objects, production tasks can be managed. Data collection aims to gather various data about the "manipulated objects," indirectly providing feedback on the production status within the factory. For production facilities of different sizes, the hardware carrier will vary during deployment; it could be the reader / writer itself, an interactive terminal, a server, a virtual machine based on several servers, or a cloud-based node.

[0046] From a physical hardware perspective, the core devices and equipment of this system are the RFID tag chips embedded in the objects being operated on and the RFID reader devices deployed at different work locations. Passive, wireless data acquisition is achieved by relying on these two devices. The interactive terminal is an auxiliary device that is logically parallel to the RFID reader device. With the development of technology, manual operation will gradually be replaced by more automated mechanical equipment, and the "interactive terminal" will also decrease or eventually be eliminated.

[0047] If we view the above sub-modules more structurally, this invention can be divided into two parts. The first part is associated with the personnel performing the operation and can be authenticated and tracked using a 13.56MHz high-frequency (NFC) RFID tag and a first-type RFID reader / writer device. This part mainly involves a task allocation module, a task assignment module, a task operation guidance module, and a task completion module. The physical carrier of this part can be an interactive terminal. The second part is associated with the object being operated on and can be authenticated, tracked, and collected by installing an ultra-high frequency (UHF) 920MHz RFID tag on the tracked object and a second-type RFID reader / writer device installed at the work point (such as a cage or operating table). This part mainly involves an operation information identification and collection module.

[0048] The modules in the first and second parts described above can communicate with the system backend (such as a database) through the information transmission module (information transmission module) and record information (information recording module); furthermore, the two parts are linked together through "operation execution". At this point, a work task is bound to a specific operator and a specific object being operated on.

[0049] The task execution review module is completed in the background, and the review results will be returned to the interactive terminal through the information transmission module.

[0050] An RFID reader / writer is a terminal computing unit equipped with a microcontroller, and can be understood as a device on par with an "interactive terminal." If the interactive terminal is the medium for interaction between staff and the back-end system, then the "RFID reader / writer device" is the medium for interaction between the operated object and the back-end system. This device also largely undertakes the computing services for the application. In essence, depending on the scale of the production facility, the various sub-modules of the above system can be deployed in the reader / writer unit for standalone use; they can be deployed in the interactive terminal, treating the interactive terminal as a computer to provide services for small-scale, localized facilities; they can be deployed on the server or on a virtual machine generated by the server to provide services for large-scale, cross-regional facility groups; or they can be deployed in a combination of one or more of the above devices for collaborative computing and service provision.

[0051] In simple terms, an RFID-based laboratory animal production management system can be understood as software or a method deployed on a hardware platform. The advantage of this system is that it enables the automatic, passive, and wireless collection, transmission, and processing of data within laboratory animal facilities. This allows for more efficient and accurate allocation, execution, and monitoring of work tasks, improving production efficiency, reducing production costs, and promoting lean production practices in the laboratory animal industry.

[0052] This invention is based on RFID technology. By deploying a large number of RFID readers within animal facilities, it tracks, locates, and identifies the status of key production objects (cages, animals, sensors, etc.) tagged with RFID tags, thereby achieving passive, wireless production data collection, transmission, and recording. The advantages of this technology are that it essentially eliminates the need for human personnel as intermediaries for data collection, transmission, and recording, greatly improving the efficiency of information acquisition, transmission, and recording, reducing the probability of errors caused by the uncertainty of human operation, lowering overall production costs, and increasing yield. Furthermore, RFID-based production data collection can also serve as a data source for machine learning and artificial intelligence, providing a foundation for production lines to achieve self-decision-making.

[0053] In one specific embodiment of the present invention, each target work task has a unique task code, which includes target work area information, work location information, target task operation object information, operation step information, and target work group information involved in the target work task; each target task operation object has a unique target task operation object code, and the target task operation object information includes one or more target task operation object codes.

[0054] When assigning target work tasks, the task allocation module performs the following steps: the task allocation module assigns the target work task with a unique task code to the interactive terminal through the information transmission module.

[0055] The target task operation object information is the core of the work task. The system automatically generates and feeds back its location information based on the target task operation object information. For example, if a customer has an order request, this order will include the required animal breed information, quantity, and some characteristic information of the animals themselves, such as sex, age, weight, etc. After receiving this customer's order, the production management system will search the system to obtain information on animals in inventory that can meet this requirement, or animals that can meet the customer's requirement in batches over a future period. This search process is achieved through RFID readers and RFID tags on animal cages or animals. Subsequently, based on the corresponding search results, a work order will be automatically generated in the production workshop (e.g., a work order to select and cage animals that meet the requirements, or to pack and ship animals that meet the requirements). This production work order will be broken down into several sub-orders and sent to different work areas to deliver the qualified animal products to the customer as quickly as possible. Therefore, the process of order generation and allocation requires the location information of the animal products first, followed by the target work area and workstation information for order delivery. The location information of animal products that meet the requirements, or will soon meet the requirements, is generated instantly after data collection and confirmation via RFID readers and RFID tags installed on the animal cages / animals. Due to the specific nature of the laboratory animal industry, each work area generally has a unique and fixed corresponding work team, and work teams and personnel in different work areas cannot overlap. However, who performs the operation within each corresponding work team is not unique. Worker identification does not mean specifically assigning the task to a particular person, but rather recording who specifically performs the operation. (In the event of cross-infection between animals, operators are most likely to become carriers of these microorganisms.)

[0056] In one specific embodiment of the present invention, each staff member of the target working group is equipped with a unique RFID badge, and each RFID badge stores a unique staff identification code. The staff identification code is used for staff identification, and the items verified include determining whether the staff member belongs to the target working group.

[0057] Each of the interactive terminals is equipped with a first-type RFID reader / writer device, and each interactive terminal has a unique first-type device code, which contains the unique location information of the interactive terminal; the first-type RFID reader / writer device can call the staff information collection module; the interactive terminal can call the task assignment module;

[0058] The task assignment module performs the following steps when assigning a task:

[0059] The staff information collection module collects the staff identification code from the RFID work badge through the first type of RFID reader / writer device; the task assignment module obtains the staff identification code from the staff information collection module; if the staff identification code belongs to the target work group and has the authority or qualification to perform the target work task, the task assignment confirmation information is displayed on the interactive terminal, the staff clicks the confirmation button on the interactive terminal, and the system background binds the task code and the staff identification code.

[0060] An interactive terminal can be understood as a shared input / output device. Once personnel and task information are confirmed, this information is temporarily stored in a designated space. When the RFID tag chip of the object being operated on (cage, animal) is identified and collected by a Type II RFID reader / writer located at the workstation, the task, the worker, and the object are linked together for easy traceability later. A task might involve operating on cages 1-10, but each operation on a cage is linked again to record the specific time information.

[0061] The core purpose of task assignment is to clearly identify which staff member, at what location, and what task they have assigned. The device code on the interactive terminal is not the key element; rather, the specific work location indicated by the terminal is crucial for traceability. When the task assignment module is operational, the touch input function of the interactive terminal (preferably a fixed terminal, as mobile terminals present inconveniences such as charging and sterilization, and the movement of a device within a cleanroom poses a risk of contamination; therefore, mobile devices should be avoided as much as possible, although they can be used in certain inconvenient scenarios) allows specific staff members to confirm and assign tasks, thus establishing ownership of the task. The interactive terminal obtains the specific task code from the production management system via its information transmission module; the terminal's RFID reader reads the staff member's RFID tag to obtain detailed staff information; a identified staff member meeting the assignment criteria can click the "Confirm" button on the terminal to bind the task code with the staff member's identification code, confirming the task's assignment to that specific staff member and establishing ownership; the binding information can then be sent to the production management system backend via the terminal's information transmission module.

[0062] Specifically, the target work area information may include the device codes of interactive terminals that meet the requirements of this target work task; the target work point information may include the location codes of fixed interactive terminals involved in this target work; and the target work team information may include the identification codes of personnel who meet the requirements of this target work task. More specifically, there may be only one or more mobile interactive devices that meet the requirements, and the personnel may choose one of them; there may also be only one or more fixed interactive devices that meet the requirements. For example, in a cage-changing operation, there are two work points: the cage rack and the cage-changing workbench, which are two fixed interactive devices; and there may be only one or more personnel who meet the requirements, and any one of the multiple members of the work team may claim the task.

[0063] Regarding task assignment, it can be done manually or automatically by obtaining the task code. For example, when a worker enters the work area, the mobile interactive terminal is already turned on and a prompt is issued for the worker to assign a task, or the worker enters the work area, turns on the mobile interactive terminal, enters the task assignment page, and then selects a task that can be assigned.

[0064] In a specific embodiment of the present invention, each target task operation object is configured with a unique RFID tag transponder, and each RFID tag transponder stores a unique target task operation object code, which is used for the identification of the target task operation object.

[0065] Each work station is equipped with a second-type RFID reader / writer device. Each second-type RFID reader / writer device has a unique second-type device code, which contains unique location information of the second-type RFID reader / writer device. The second-type RFID reader / writer device can call the operation information identification and acquisition module. The operation information identification and acquisition module obtains the target task operation object code from the RFID tag transponder through the second-type RFID reader / writer device to capture the operation execution status information, and binds the task code, the worker identity code, and the target task operation object code.

[0066] The operation information recognition and acquisition module performs the following steps when capturing the operation execution status information:

[0067] The operation information identification and acquisition module captures the operation execution status information based on the target work task and access disconnection status information;

[0068] The access disconnection status information is generated by the second type of RFID reader / writer device monitoring the access disconnection status of the RFID tag transponder.

[0069] Each product / job / operation object is assigned a unique identity. RFID technology is used to collect data on the location of these objects within the work area, as well as their workflow, process, and points of contact, including sensor status data. This automatically collected data (AIDC) can serve as raw data for machine learning. The results of machine learning, once returned to the production line, can guide actual operations, thereby achieving a more lean production process.

[0070] In practical implementation, for example, the second type of RFID reader / writer can actively poll, sending a radio frequency signal every 500 milliseconds to detect the RFID tag transponder of the target task object. When the tag enters the reader's effective identification range (e.g., an area with a radius of 2 cm), the tag is activated and returns a signal, and the reader records information such as the tag access time and signal strength; when the tag leaves the identification range, the reader records the disconnection time. The second type of RFID reader / writer can send access and disconnection information to the system backend through an information transmission module. For example, in an animal transfer task, if the reader detects that the tag of the container containing the experimental animal is disconnected at the source location and connected at the target location, and the time interval meets the transfer time range specified in the task, the system backend generates operation execution status information, indicating that the animal transfer operation has been completed. The operation execution status information can be stored in the database of the system backend, using the task code and operation step identifier as a joint primary key.

[0071] Existing technologies rely heavily on manual recording to capture the operational status, making it difficult to obtain real-time and accurate operational status information. This invention utilizes RFID tag access and disconnection information to generate operational status information, achieving real-time and automatic monitoring of the operation process and accurately determining the completion status of operational steps. In laboratory animal production, accurately grasping the operational status is crucial for ensuring production quality and efficiency. The solution of this invention can promptly detect abnormalities in operation, such as omitted steps or excessively long operation times. For example, during animal husbandry, if the cage-changing operation time exceeds the normal range, the system can promptly issue an alarm, reminding staff to check the work site or the animal's condition. Through precise monitoring of the operational status, animal health problems and production accidents caused by improper operation are effectively avoided, improving the level of lean production management.

[0072] Taking the scenario of changing laboratory animal cages as an example: The target task is to replace laboratory animal cages. When the worker picks up the cage containing the laboratory animal from its original rack, the RFID reader installed on the rack collects the disconnection information of the RFID tag on the cage. This information is transmitted to the system backend via the information transmission module. The system backend, combined with the target task, determines that this may be the start of the "removing the cage from the original rack" step in the cage replacement operation. When the worker places the cage on the cage-changing workbench, the RFID reader on the workbench collects the access information of the cage tag and transmits it to the system backend. The system, based on the task flow, determines that the step of "removing the cage from the original rack and placing it on the cage-changing workbench" has been completed. If no corresponding access or disconnection information is detected within a specified time (e.g., 3 minutes, reasonably set according to actual operation), the system can determine that the operation is abnormal and the current step has not been completed normally.

[0073] In one specific embodiment of the present invention, the interactive terminal may also call the task completion module; the task completion module is used to release the task through the interactive terminal after the staff member who made the task assignment completes the target work task and the actual operation passes the review of the task execution review module.

[0074] The task completion module performs the following steps when releasing the target work task:

[0075] The staff information collection module collects the staff identification code from the RFID work badge through the first type of RFID reader / writer device; the task completion module obtains the staff identification code from the staff information collection module; if the staff identification code and the task code are bound together, and the review result of the task execution review module is "approved", then the interactive terminal displays a confirmation message for task release. The staff clicks the confirmation button on the interactive terminal, and the system backend releases the binding relationship between the task code, the staff identification code, and the target task operation object code.

[0076] When the task completion module is active, all operations for a task can be completed and verified. All relevant information has been recorded in the animal production management system's database. The worker can then unbind the task assignment module and wait to receive the next task assignment. Regarding task cancellation, it can be configured so that this interface only appears after all tasks are completed and all steps of the tasks have passed consistency verification; alternatively, it can be configured to allow cancellation midway to handle unexpected situations.

[0077] In practical implementation, for example, each target task can be assigned a unique task code. The coding rule can be generated using a combination of timestamps, work type codes, and serial numbers, such as "20241001001001," where the first 8 digits represent the date, the middle 3 digits represent the work type, and the last 3 digits are the serial number for that type of work on that day. Each worker is equipped with a unique RFID badge, and their identification code is stored in a chip. Each interactive terminal has a unique device code, which can be burned and solidified during equipment production. The task code includes target work area information, target work location information, and target work group information, such as "01-05-03," which represents the 1st work area, the 5th work location, and the 3rd work group, respectively. When a worker claims a task through the interactive terminal, the interactive terminal's information transmission module can send a request to the system backend to obtain the task code. After verifying the legitimacy of the interactive terminal, the system backend can return the task code in JSON format. The RFID reader uses a 13.56MHz frequency to read the RFID employee ID code. It compares the read employee ID code with the target work group information in the task code. If a match is found, the interactive terminal screen displays a pop-up confirming the task assignment, including task details (task name, estimated duration, etc.). The employee clicks the confirm button, and the interactive terminal sends the task code and employee ID code to the system backend via the network module. The system backend stores this information in a database table, completing the binding. When the employee cancels the task through the interactive terminal, the RFID reader reads the employee ID code again and queries the database table. If the employee ID code and task code are still bound, the interactive terminal displays a confirmation of task cancellation, which may include a brief description of the task completion status (completed steps, incomplete steps, etc.). The employee clicks the confirm button, and the system backend deletes the corresponding binding record from the database table, releasing the binding relationship.

[0078] In existing technologies, task assignment and release methods mostly rely on manual registration or simple account password verification, lacking close linkage with personnel and equipment and automated processes. This invention, through a unique coding system and RFID technology, enables precise binding and release of tasks, personnel, and equipment, improving not only the accuracy and efficiency of task management but also enhancing traceability. This task assignment and release method based on coding and RFID technology represents a completely new design approach compared to traditional methods. In experimental animal production management scenarios, traditional task assignment and release methods are prone to problems such as mismatch between personnel and tasks and difficulty in tracking task progress. The solution of this invention achieves automatic task allocation and precise association. When personnel are transferred or tasks are adjusted, the system can respond quickly and reassign tasks. For example, if the staff member originally responsible for feeding animals in area A has an emergency, the system can quickly reassign the task to other members of the same group and accurately record the task flow process. Simultaneously, the binding relationship allows real-time monitoring of the personnel and equipment usage for each task, facilitating management and supervision—something difficult to achieve with traditional methods.

[0079] In one specific embodiment of the present invention, the task operation guidance module performs the following steps when sending the guidance information:

[0080] The task operation guidance module obtains the operation execution status information from the operation information recognition and collection module, determines the guidance information that should be sent for the current operation step based on the operation execution status information, and displays the guidance information for the current operation step to the staff in the form of text, images or sound through the interactive terminal.

[0081] In practice, for example, the system background can push operation execution status information to the fixed interactive terminal in real time. After receiving the information, the fixed interactive terminal parses the operation step identifier (such as "step001", "step002", etc.) and task progress information (number of completed steps, current step time, etc.). Based on a preset guidance information mapping table, it determines the guidance information to be sent for the current operation step. The guidance information can be stored in the local database of the fixed interactive terminal, indexed by the operation step identifier as the primary key. The fixed interactive terminal presents the guidance information to the staff in the form of text, images, or sound. If presented in text form, detailed operation instructions can be displayed in a specific area of ​​the interactive terminal screen (such as the bottom information bar); if presented in image form, images corresponding to the operation steps can be read from the locally stored image library, with operation points marked on the images; if presented in sound form, pre-recorded voice guidance content can be played by calling the audio playback interface of the interactive terminal, and the voice content includes operation steps, precautions, etc.

[0082] In existing technologies, operational guidance often provides all instructions at once or in simple paper guides, failing to provide real-time guidance based on the progress of the operation. This invention dynamically sends guidance information based on the operation's execution status and offers multiple display formats, achieving personalized and precise operational guidance. In laboratory animal production operations, complex procedures and high-standard requirements make operators prone to errors. The dynamic guidance system of this invention significantly improves the accuracy and efficiency of operators. For example, during laboratory animal surgery, operators can accurately complete the procedure based on real-time guidance at each step, reducing animal injuries and experimental failures due to operational errors. Simultaneously, the multiple display formats cater to the learning and operational habits of different operators, improving operational convenience.

[0083] In one specific embodiment of the present invention, the target task operation object includes experimental animals and / or animal containers and / or sensors; the sensors include temperature sensors and / or humidity sensors and / or weight sensors and / or liquid level sensors and / or pressure sensors; the experimental animals are equipped with a first type of RFID tag transponder, the animal containers are equipped with a second type of RFID tag transponder, and the sensors are equipped with a third type of RFID tag transponder.

[0084] The operation information identification and acquisition module performs the following steps when collecting the operation execution status information:

[0085] The operation information identification and acquisition module reads the first type of RFID tag transponder through the second type of RFID reader / writer device to collect the identification information and location information of the experimental animal; and / or, the operation information identification and acquisition module reads the second type of RFID tag transponder through the second type of RFID reader / writer device to collect the identification information and location information of the animal container; and / or, the operation information identification and acquisition module reads the third type of RFID tag transponder through the second type of RFID reader / writer device to collect the measurement data information and location information of the sensor.

[0086] Temperature sensors are used to monitor the temperature of the environment in which laboratory animals live in real time. Laboratory animals have strict requirements for the temperature of their living environment; excessively high or low temperatures can interfere with their normal physiological functions and affect the accuracy of experimental data. For example, the optimal living temperature for mice is typically 22℃±2℃. The temperature sensor continuously collects temperature data and transmits it to the system backend via RFID tags. Once the temperature exceeds the preset reasonable range, the system immediately issues an alarm and automatically adjusts (laboratory animal facilities require constant temperature and humidity 24 hours a day, 365 days a year, and the fluctuation range of standard values ​​is very small; therefore, only automatic adjustment control mechanisms can be used) to ensure that the animals live in a suitable temperature environment and that experiments can proceed smoothly.

[0087] Humidity sensor: This sensor monitors the humidity level of the environment in which laboratory animals live. Humidity has a significant impact on the health of laboratory animals. Excessive humidity can promote the growth of bacteria and fungi, leading to animal diseases; conversely, insufficient humidity results in dry air, which may cause respiratory discomfort. For example, when raising mice, the ideal humidity level is generally controlled between 40% and 70%. The humidity sensor monitors humidity in real time and uploads the data. The system uses this data to determine whether the humidity is suitable, and if any abnormalities are detected, it automatically adjusts the humidity level to create a stable environment for the animals.

[0088] Weight sensors: These can be used to measure the weight of laboratory animals or supplies such as feed and drinking water. Measuring animal weight and uploading the data to the production management system via RFID tags and readers facilitates rapid animal selection. In drug experiments, ensuring the animals' weight meets standards is a crucial indicator of drug efficacy. Simultaneously, monitoring changes in feed and drinking water weight allows for understanding animal feeding and drinking habits, assessing their health, and promptly alerting staff to replenish supplies, preventing shortages from impacting animal growth and experimental progress.

[0089] Liquid level sensors are used to monitor the liquid level in animal drinking water containers or other liquid containers. Ensuring animals have access to a constant supply of clean drinking water is crucial in laboratory animal husbandry. Liquid level sensors monitor water levels in real time, and when the level falls below a set threshold, the system promptly alerts staff to add water, ensuring the animals' drinking needs are met. In certain specialized experimental scenarios where precise control of liquid usage is required, liquid level sensors can also provide accurate data support for experimental operations.

[0090] In practical implementation, for example, RFID tags for laboratory animals can be subcutaneously implanted or ear-tagged. The tag chip stores the animal's identification information (a unique identification code that serves as the key in a database, linking the animal's breed, genetic information, date of birth, etc.) and location information (the location information is assigned through the location code of the RFID reader; when object A is captured and identified by reader X, object A is considered to be within the location area of ​​X). For example, a mouse with the tag number "001" stores the identification information "C57BL / 6-001-20240101" and the location information "X:10.5,Y:5.2,Z:0.3", representing its coordinate position in the laboratory coordinate system. RFID tags for animal containers are attached to the surface of the containers, using adhesive or embedded methods. The tags store the container's identification information (such as container type, number, and region) and location information (also obtained through communication with the RFID reader device). For example, a mouse cage numbered "V005" might have a tag storing the identification information "MouseCage-V005-A01," indicating that it is the 5th mouse cage in area A01. The RFID tag for the sensor is integrated inside the sensor. Taking a temperature sensor as an example, the tag not only stores the sensor's identification information (such as manufacturer, model, and serial number), but can also collect and store temperature measurement data (with an accuracy of ±0.1℃) and location information in real time. The sensor writes the measurement data into the tag according to a specific data format (such as JSON format: {"sensor_id":"T001","temperature":"22.5","location":"X:15.0,Y:8.0,Z:1.0"}), and the tag then transmits the information to the RFID reader on the interactive terminal via radio frequency signals.

[0091] In existing technologies, information collection methods for laboratory animals, animal containers, and sensors are relatively simple and cannot achieve unified management and real-time tracking (real-time tracking and positioning can be defined as a function of the data acquisition module, collecting the location information of the manipulated object). This invention achieves integrated management of identification, location tracking, and data collection for multiple objects by installing RFID tags on different target tracking objects. In laboratory animal production management, comprehensive and real-time information collection is crucial for ensuring animal health and experimental accuracy. The solution of this invention enables comprehensive monitoring of the living environment and the animal's own condition. For example, temperature and humidity sensor tags can monitor changes in temperature and humidity in the animal's living environment in real time. When environmental parameters exceed suitable ranges, the system automatically issues an alarm, reminding staff to adjust environmental conditions. Simultaneously, by tracking the location of animal containers and animals, staff can quickly locate and manage them, improving work efficiency—effects that are difficult to achieve with traditional information collection methods.

[0092] In a specific embodiment of the present invention, the task execution audit module includes the following steps when performing consistency audits between actual operations and SOPs:

[0093] Verify whether the specific task operation object of the actual operation is consistent with the target task operation object; and / or verify whether the specific content of the actual operation is consistent with the target work task; and / or verify whether the operation steps of the actual operation are consistent with the guidance information.

[0094] A key aspect of the task execution review module is preventing confusion between operations. For example, when weaning animals in a specific cage (after a three-week lactation period, pups are separated from their mothers and moved to the rearing stage), traditional work methods lack automated mechanisms for identification, comparison, and review based on digital technology. This often leads to the wrong cage being used, such as mistakenly weaning newborn lactating animals. This is undoubtedly a work accident and will result in losses. The task execution review module of this invention effectively avoids this risk.

[0095] In practice, when verifying whether the specific content / object of the actual operation matches the target work task / object assigned by the task allocation module, the system backend can read the task allocation information from the task management database, including the task type (such as adding feed to animals, changing cages, etc.), task content details (feed amount, operation steps, etc.), and the specific task object. Information collected during the actual operation (such as the amount of feed recorded during feeding operations, and the execution status of operation steps recorded during cage changing operations) is compared with the task allocation information. When verifying whether the personnel performing the actual operation match the personnel who claimed the task in the task assignment module, the system backend can retrieve the personnel identification code bound at the time of task assignment from the task assignment record database and compare it with the operator identification code obtained through the interactive terminal during the operation (obtained by reading the RFID work badge). If the two match, the operator is deemed to meet the requirements. In this operational scenario, the interactive terminal is installed in two locations: one on the cage rack and one on the operating table. The interactive terminal on the cage rack will inform you which cage box to retrieve. At this point, the identity authentication process will record who retrieved the cage box (due to sterility and cleanliness requirements, the personnel transporting the cage box and the operator are usually separated to avoid frequent disinfection procedures). After that, the step of retrieving the cage box is completed. When the cage box is transferred to the cage rack, the interactive terminal on the cage rack will provide operation instructions, start a new operation step, and authenticate the specific operator, recording who performed the operation task for this cage box.

[0096] When verifying whether the actual operation steps are consistent with the guidance information sent by the operation guidance module, the system backend can record each step of guidance information sent by the operation guidance module (including the sending time and content of the guidance information), and simultaneously record the steps and time actually performed by the operator. For example, in the screening of experimental animals, the operation guidance module sends guidance information for screening operation steps 1, 2, etc., in sequence. The system compares the order and time of the steps actually performed by the operator to determine whether it is consistent with the guidance information. If inconsistencies are found, the system records the differences in detail (such as skipped steps, incorrect step execution order, etc.).

[0097] Existing technologies for operational auditing largely rely on periodic manual checks or simple post-event verifications, which are inefficient and prone to oversights. This invention constructs a comprehensive and automated consistency auditing mechanism, conducting real-time audits across four dimensions: operational content, operational objects, operators, and operational steps. This multi-dimensional and automated auditing approach significantly improves the comprehensiveness, accuracy, and timeliness of audits compared to traditional auditing techniques. In laboratory animal production, ensuring operational consistency is crucial for guaranteeing the reliability of experimental results and animal quality. This invention's consistency auditing mechanism effectively reduces operational errors and violations. Strict operational step auditing avoids experimental failures and animal waste due to improper operation, improving experimental success rates and animal resource utilization. Simultaneously, the real-time auditing function allows for timely detection and correction of problems, reducing the potential risks associated with erroneous operations.

[0098] In one specific embodiment of the present invention, if the consistency audit fails, the system backend sends a warning message to the interactive terminal bound to the target task; if the consistency audit passes, the fixed interactive terminal begins to send guidance information for the next step.

[0099] In practice, for example, if the consistency audit fails, the system backend retrieves the interactive terminal information bound to the target task (from the task allocation record database) based on the task code, including the device codes and network addresses of mobile and fixed interactive terminals. The system backend sends warning messages to these interactive terminals via a network push service (such as JPush). The warning message is displayed as a pop-up on the interactive terminal screen, titled "Operation Anomaly Prompt," detailing the anomaly (e.g., "Operation Step Error: Step 3 should be executed after Step 2," "Operation Object Mismatch: The current operation object is XXX, it should be XXX," etc.), and provides a link to the operation specification guidance; clicking the link allows viewing the correct operation process and standards. If the consistency audit passes, the fixed interactive terminal reads the guidance information for the next step from the guidance information database. The guidance information database stores guidance information in the order of operation steps, with each guidance information record containing fields such as step number, guidance content, and display format. The fixed interactive terminal retrieves the guidance information corresponding to the next step number based on the current operation step number and presents it to the staff according to the set display format (text, image, or sound).

[0100] Existing technologies lack timely and effective warning mechanisms when dealing with operational inconsistencies, and the consistency and standardization of operational procedures are difficult to guarantee. This invention designs precise warning and guidance measures for consistency audit results. Through timely warning information and automatic push of next-step guidance information, dynamic management and optimization of the operational process are achieved. In laboratory animal production management scenarios, timely correction of operational errors and guidance to correct operational procedures are crucial. The solution of this invention can effectively avoid subsequent problems caused by undetected operational errors, such as experimental failure and damage to animal health. For example, in in vivo pharmacodynamic testing experiments, once an operational error is detected and corrected in time, the experiment can be carried out smoothly, reducing experimental costs and animal losses. At the same time, the automatic push of next-step guidance information improves the continuity and efficiency of the operator's work, an effect that is difficult to achieve with traditional operational management methods.

[0101] When the information transmission module is working, it can transmit the signal of the target object being tracked via RFID tags to the RFID reader / writer device via radio frequency signals. The signal is then demodulated and converted into a digital signal, which is then transmitted to the animal production management system via the information transmission module. For RFID tags used only for identification, the unique identification code is compiled and transmitted to the RFID reader / writer device via carrier wave. Upon receiving the signal from the RFID tag, the RFID reader / writer device demodulates it, translates it into digital information, and then transmits it to the backend of the animal production management system via the network module. The target object being tracked can be a container, an animal, changes in temperature and humidity, the consumption of feed and drinking water, or any event in the production process that has data collection value.

[0102] In one specific embodiment of the present invention, the information recording module is used to record the information streams generated by the task allocation module, the task assignment module, the task operation guidance module, the task execution review module, the task completion module, the staff information collection module, the operation information identification and collection module, and the information transmission module into a database.

[0103] In specific implementation, for example, when the task allocation module performs a task allocation operation, the information recording module records the task allocation time (accurate to milliseconds, using a system timestamp), location (work area and work location information parsed from the task code), operator identity (obtaining the operator's RFID badge identification code from the interactive terminal performing the task allocation operation), and the specific content of the task allocation (task code, task details, etc.). This information is stored in a structured data format (such as JSON format: {"time":"20241010101010.123","location":"A01-05","operator_id":"001","task_assignment":"{...}"}) in the "task_assignment_log" table of the MySQL database in the system backend. In the task claiming module, the time, location, operator identity, and task claiming confirmation information (task code, confirmation time, etc.) of the staff claiming the task are recorded and stored in the "task_claim_log" table. In the operation guidance module, the time, location, operator identity, content of the guidance information, and the interactive terminal device code receiving the guidance information are recorded for each transmission of guidance information and stored in the "operation_guidance_log" table. In the operation information identification and collection module, the time sequence information of operation execution (operation start time, execution time of each step, operation end time), location, operator identity, and operation execution status information (such as operation success, failure, interruption, etc.) are recorded and stored in the "operation_execution_log" table. In the information collection module, the time, location, operator identity, and content of the collected target tracking object information (animal identification information, container location information, sensor data, etc.) are recorded and stored in the "information_collection_log" table. In the information transmission module, the time, location, operator identity, sender device code, receiver device code, and content of the transmitted information are recorded and stored in the "information_transmission_log" table. In the task execution audit module, the audit time, location, operator identity, audit result (pass or fail), and reasons for audit failure (details such as operation content inconsistency, operator inconsistency, operation steps inconsistency, etc.) are recorded and stored in the "task_execution_audit_log" table.

[0104] Existing technologies for recording information in the laboratory animal production management process are often incomplete, non-standardized, and lack systematicity and coherence. The information recording module of this invention comprehensively and systematically records the information flow of each stage of production management, establishing a complete log system. Through a unified recording format and a linked database table structure, efficient information storage and retrieval are achieved. In laboratory animal production management, complete information recording is crucial for tracing the production process, analyzing problems, and optimizing workflows. The information recording module of this invention provides detailed data support for production management. For example, when laboratory animals experience health problems, the source of the problem can be quickly traced and possible causes (such as improper operation or environmental changes) can be analyzed by querying operation execution records and environmental monitoring data. Simultaneously, through the analysis of a large amount of recorded data, bottlenecks and optimization points in the production process can be identified, improving production efficiency and quality—effects that exceed the capabilities of traditional information recording methods.

[0105] In one specific embodiment of the present invention, each piece of information recorded by the information recording module includes time attributes, location attributes, operator identity attributes, and operation object attributes. The information recorded by the information recording module includes: binding information between the worker and the interactive terminal; and / or, binding information between the worker and the target work area / work location; and / or, binding information between the worker and the target work task; and / or, information triggered by the worker's operation actions; and / or, consistency verification result information.

[0106] When the information recording module is working, it can be executed synchronously with each process in the task allocation module, task assignment module, task operation guidance module, operation information collection module, task completion module, information transmission module, and task execution review module. It records the information flow generated in each process module within the animal production management system's database. It can be used to record the binding information between specific workers and mobile interactive terminals, workers and work areas / locations, workers and tasks, and workers and their operating objects in the task allocation module; record worker confirmation feedback information in the task assignment module; record information triggered by each operation action in the operation information recognition and collection module; and record each review result in the task execution review module. Each piece of recorded information includes at least four basic attributes: time, location, operator identity, and operating object identity.

[0107] In practical implementation, for example, the time attribute of each piece of information recorded by the information recording module is accurate to the second with a timestamp obtained through the system clock. For instance, "20241115142330" represents 14:23:30 on November 15, 2024, ensuring accurate traceability of the operation's occurrence time. The location attribute can be determined based on the work area and work point information in the task code, combined with a positioning module (such as Wi-Fi or Bluetooth positioning technology, or RFID positioning technology) to obtain real-time location information. The positioning accuracy can reach tens of centimeters indoors, and this information is converted into a corresponding work area identifier. The operator's identity attribute is obtained from the RFID work badge identification code read from the interactive terminal. This identification code is associated with the personnel information database, allowing for the querying of detailed information such as the operator's name and department. Regarding the recorded binding information between staff and interactive terminals, the information recording module records the binding time, interactive terminal device code, staff identification code, and the work area and location information where the binding occurs when a staff member uses the interactive terminal to claim or perform a task. For example, if staff member "001" uses mobile interactive terminal numbered "T005" at work location "A02-03" at work location "20241115142000", this binding information will be recorded in detail. For the binding information between staff and work areas / locations, the binding relationship and effective time are recorded in conjunction with the staff identification code. For example, if task "0001" is assigned to staff member "002" to perform an operation on animal XXX at work area and location "B01-07", this binding relationship is recorded at "20241115143000". For the binding information between staff and work tasks / objects, it can be recorded after the task is successfully claimed, including the task code, staff identification code, claim time, and estimated completion time. For example, if staff "003" claims task "0002" at "20241115143500" and expects to complete it at "20241115160000", this information will be accurately recorded. For information triggered by staff operation actions, it can be recorded after the operation information recognition and acquisition module captures the operation action. For example, in the operation of adding feed to experimental animals, when the RFID reader / writer device on the operating table recognizes the tag of the container containing feed and the tag of a cage, and the current task allocation module assigns the scenario of adding feed, it is considered as a feed adding operation triggered, and the operation time, the object being operated on (cage code, animal code, feed batch code, etc.), and the location information of the operation are recorded. The results of the consistency audit can be recorded after the task execution audit module completes the audit. Record the audit time, audit result ("pass" or "fail"), and if it fails, record the reasons for failure in detail (such as "the actual operation steps do not match the SOP, and the order of steps 2 and 3 is reversed"), and information such as the code of the operated object involved does not match.

[0108] Existing technologies for information recording typically focus only on key business data, neglecting related information during the operation process. Furthermore, the recording methods are fragmented, lacking systematicity and coherence. The information recording module of this invention not only records various operation-related information in detail but also closely links multi-dimensional information such as time, location, operators, and operated objects with business operations. This comprehensive and interconnected information recording method breaks the traditional recording model, constructs a complete operational information chain, and provides a rich data foundation for subsequent data analysis, process traceability, and optimization. In the field of laboratory animal production management, the technical effects brought by the information recording module of this invention exceed conventional expectations. By recording multi-dimensional related information, when abnormal conditions occur in laboratory animals or experimental results deviate, rapid and accurate full-process traceability can be achieved. For example, if a batch of laboratory animals is not growing well, a comprehensive analysis can be conducted based on information such as time, location, and operators, drawing from feed addition records, environmental monitoring records, and experimental operation records, to accurately pinpoint the problem. This could be due to improper operation by a specific operator at a particular time and place, or abnormal fluctuations in environmental factors. At the same time, this wealth of data can provide a strong basis for optimizing production processes. By analyzing the execution effects of different operations at different times and locations, potential optimization points can be discovered, improving overall production efficiency and quality. These in-depth analyses and optimization effects are difficult to achieve with traditional, fragmented information recording methods.

[0109] like Figure 1 As shown, the present invention also provides a management method for a laboratory animal production management system based on RFID technology, comprising the following steps:

[0110] The task assignment module sends the target work task to the interactive terminal; the interactive terminal allows staff belonging to the target work group to claim the task, thus binding the task code and staff identification code; the second type of RFID reader / writer binds the task code, staff identification code, and target task operation object code; the interactive terminal sends guidance information to the staff step by step so that the staff can perform the work task operation according to the guidance information; the operation information identification and collection module captures the operation execution status information of the staff on the target work task; the information transmission module sends the collected operation execution status information to the task execution review module; the task execution review module compares and verifies the consistency of the operation execution status information and the breakdown steps of the SOP; if the consistency review fails, a warning message is sent to the interactive terminal; when the staff completes the target work task and the actual operation passes the consistency review, the staff releases the task through the interactive terminal to unbind the task code, staff identification code, and target task operation object.

[0111] Existing methods for managing laboratory animal production largely rely on manual operation and recording, resulting in untimely and error-prone information transmission. For example, traditional methods may assign tasks via paper documents or verbal communication, leading to unclear task assignments and staff unaware of their responsibilities. During task execution, the lack of real-time operational guidance and monitoring forces staff to rely on memory or paper-based instructions, resulting in low accuracy and efficiency. Information collection and verification during operations are often done manually afterward, failing to promptly identify and correct errors, leading to low production efficiency, unstable animal quality, and high management costs. This invention's management method, based on RFID and a digital system, automates and digitizes the entire process of task allocation, assignment, execution, verification, and release. A unique task code, identity code, and equipment code system ensures precise association between tasks, personnel, and equipment. Real-time communication between interactive terminals and the system backend enables real-time push of operational guidance information and real-time collection of operational status. A consistent verification mechanism detects and corrects operational errors in real time. This fully automated and digitized management approach represents a qualitative leap from traditional methods, both in management model and technological means.

[0112] To enable those skilled in the art to more clearly understand the beneficial technical effects of the present invention, the following are some further examples of process steps that can be optimized using the technical solutions of the present invention:

[0113] 1. Obtaining work tasks

[0114] Obtaining work assignments is often the first task upon entering a barrier facility. Traditionally, these assignments are posted on the barrier's glass windows. Once inside, staff can view the assignments through these windows, making the windows a primary communication medium between the inside and outside of the barrier facility. Currently, many facilities still use this method.

[0115] With technological advancements, some facilities pre-install computer terminals within barriers, with one terminal shared across an entire barrier area. Once inside, staff can communicate with those outside the barrier via these terminals. However, even with this method, it's still necessary to transcribe information from the computer terminal or manually input completed tasks. The difference from the previous method is simply that information is now read from a computer screen instead of a glass window; it doesn't fundamentally alter the way staff transmit information.

[0116] Based on this invention, the workflow for obtaining work tasks in the two methods described above can be essentially eliminated. After entering the facility, staff can activate the interactive terminal installed at each workflow point using their identification badge to obtain the corresponding work task information. The work execution status and results no longer need to be manually recorded and transmitted; instead, they are automatically entered into the production management system's database by RFID tags and readers.

[0117] 2. Locating the animal's location

[0118] Traditionally, the layout of cages and enclosures is planned in advance, with each animal assigned a fixed area, shelf, and enclosure, similar to library management. This facilitates easy retrieval by staff. Staff must navigate to the correct area and shelf within the pre-defined space to find the animal they need to handle. However, this approach limits the cage placement ratio to some extent. Animals from different zones cannot be placed together, resulting in idle resources when one zone is not fully utilized. Conversely, when one zone is overcrowded, other controlled zones cannot be used due to confusion.

[0119] Based on the system of this invention, the system can track specific cages and specific animals. Therefore, a cage full of animals can be placed on a cage shelf in any area. The RFID-based production management system will tell the staff (e.g., displaying relevant information on the screen of the interactive terminal) where to retrieve the task object for this operation. Furthermore, based on the relationship between the workflow points and the arrangement of the feeding cages, the system can assign tasks according to proximity, reducing the distance and time spent traveling between the work station (work point) and the feeding cages. More importantly, it is difficult for staff to pick up the wrong object, and even if an error occurs, the system will issue a warning immediately, which greatly improves production efficiency and accuracy.

[0120] 3. Filling out and updating animal information tags

[0121] Traditional animal information signs are handwritten and hung in front of their cages for easy reference by staff. However, problems frequently arise, such as errors in filling out the forms, untimely or forgotten updates, illegible handwriting leading to misreading, and even signs being hung on the wrong cages. Because staff in the facility must wear protective clothing, goggles, and gloves, writing is very inconvenient, and it often results in staff members themselves being unable to decipher their own handwriting.

[0122] This system invention breaks away from traditional information recording and transmission methods, eliminating the need for these steps. Based on this system, information is recorded seamlessly in a database for each operation. Staff only need to click a few basic confirmation buttons on the interactive terminal to automatically generate and update animal information tags in real time. The physical hanging method also disappears, with all information accessed through the interactive terminal. This minimizes the impact of information interaction issues on production costs, quality, and efficiency.

[0123] 4. Cage replacement

[0124] like Figure 2 As shown, the traditional cage replacement operation process includes at least (1) entering the facility, (2) obtaining work information, (3) finding the work object, (4) taking out the cage, (5) finding the cage replacement workbench, (6) changing the cage, (7) recording work information, (8) returning the cage to its original position, (9) taking the work record out of the barrier, (10) organizing the information, and (11) entering the information into the system, totaling 11 work steps, involving 2 work points (cage rack and cage replacement workbench) and 4 operators.

[0125] like Figure 3 As shown, the cage-changing workflow based on the system of the present invention only requires five steps: (1) entering the facility, (2) obtaining information and taking out the cage, (3) changing the cage, (4) returning the cage to its original position, and (5) leaving the facility. Based on the present invention, the work related to information acquisition, recording, and transmission is synchronized with the operation and is automatically completed by the RFID device and production management system; the recording, transmission, and verification of work information are all automatic and imperceptible; since the mobile interactive terminal and the fixed interactive terminal can receive and present the target work task information, the location of the cage and the work point to be visited (e.g., the cage-changing work station) can be quickly and obviously indicated to the staff, thus saving a lot of time and effort spent on finding the work object, finding the cage-changing work station, and other search-related work. Based on this, the present invention can omit steps (3), (5), (10), and (11) in the traditional cage replacement operation, merge steps (2) and (4) in the traditional cage replacement operation into the current step (2), merge steps (7) and (8) in the traditional cage replacement operation into the current step (4), and simplify step (9) in the traditional cage replacement operation into the current step (5). Due to the merging and simplification of steps, the investment in auxiliary and supervision work can be reduced, and therefore the number of operators can also be reduced accordingly.

When verifying whether the staff performing the actual operation is consistent with the staff who claimed the task in the task assignment module, the system backend retrieves the staff identification code bound when claiming the task from the task assignment record database and compares it with the operator identification code obtained through the interactive terminal during the operation. If the two are consistent, the operator is deemed to meet the requirements. When verifying whether the actual operation steps are consistent with the guidance information sent by the operation guidance module, the system background records each step of the guidance information sent by the operation guidance module, and at the same time records the actual steps and time of the operation performed by the operator.
