Description

Technical Field

[0001] The present invention relates to the technical field of life science research, and in particular to an experimental animal production management system and method based on RFID technology. Background Art

[0002] With the development of life science and technology and people's increasing attention to life and health, the market demand for experimental animals is increasing, and more and more attention is paid to the quality of experimental animals.

[0003] The production, use, and management of laboratory animals in the industry are largely manual, resulting in low production efficiency, inconsistent animal quality, heavy workloads, and high production and management costs. In particular, most facilities for the production and use of laboratory animals are cleanroom facilities with strict access restrictions, increasing management difficulties and hindering information transfer.

[0004] Existing laboratory animal production management systems on the market are mostly computer systems deployed outside of containment facilities and rely on manual data entry. These systems lack direct connectivity with frontline processes within the facility, making it difficult to achieve coordination, scheduling, and real-time data updates and feedback across production processes. Some production management systems incorporate methods for scanning animal tags using handheld mobile devices to connect animals to management databases. However, this method primarily links animals to animal information management systems and does not enable the collection, transmission, processing, and feedback of data across the production process. This inability to coordinate cross-process collaboration to improve production efficiency, animal quality, and reduce production costs is crucial. Furthermore, these handheld terminal devices cannot accurately locate animals of different strains, ages, or groups, and still rely heavily on manual operation. For facilities with annual production of millions of animals and cages holding tens of thousands of animals, these methods offer limited efficiency gains.

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

[0018] (3) Enhance management efficiency: The present invention realizes the precise binding and release of tasks, personnel and operation objects through a unique task coding, staff identity coding and target task operation object coding system. The system can track the progress of tasks in real time, view the executors, operation objects and execution progress of each task, and facilitate 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 of production management, including task allocation, claiming, operation execution, review and other information, and associates time, location, operation object and operator identity attributes. These rich data provide strong support for production process tracing, problem analysis and optimization, help to find bottlenecks and optimization points in the production process, and improve the overall management level. The data collected by the information recording module in the present invention can be used as raw data for machine learning and intelligent factory AI algorithms. The automated data collection, transmission and processing of the present invention can reduce manual operation links and reduce labor costs. At the same time, it avoids resource waste caused by manual recording errors, chaotic animal information management, etc., and further reduces production management costs.

DETAILED DESCRIPTION

[0021] This invention can be used in a variety of laboratory animal production processes, with its application value particularly evident in the production of rodents. Existing technologies in rodent production processes are unable to coordinate and collaborate across production processes. Collaboration between different production processes refers to digitally collecting, transmitting, processing, and providing feedback for each distinct process within the overall production process (work flow), rather than simply collecting information about the produced object. Digitizing processes can greatly improve the efficiency of communication and collaboration between processes. For example, in a production process with five processes, when a change occurs in one process, traditional methods require that information about the change be transmitted individually, along with the flow of the produced object to the other processes. This information cannot be immediately and synchronously transmitted to the other four process units, hindering timely response and adjustment. However, this invention, leveraging RFID technology, enables 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. Once a process changes, the system can quickly synchronize the information to other processes, allowing each link to respond and adjust in a timely manner. For example, in processes such as rodent breeding, feeding, experimental preparation, and experimental operation, changes in animal reproduction can be immediately fed back to subsequent feeding, experimental preparation, and other processes, allowing staff to adjust feeding plans and experimental arrangements in a timely manner. This greatly improves overall production efficiency and management accuracy, and effectively solves the problems of existing technologies. From the perspective of lean production theory, this is a shift from the traditional pull production model between processes to a collaborative production model between processes.

[0022] Traditional pull production model such as Figure 5 As shown, the production process can only be controlled at the beginning and end, and the change information can only be transmitted one by one between the processes in the middle. The production management model based on the digital technology of the embodiment of the present invention is as follows Figure 6 As shown, when production changes, each production process can be adjusted simultaneously.

[0023] like Figure 4 As shown, the present invention provides an experimental animal production management system based on RFID technology, comprising: A work task management subsystem includes a task allocation module, a task claiming module, a task operation guidance module, a task execution review module, and a task completion module; a staff management subsystem includes a staff information collection module; the staff management subsystem is deployed on an interactive terminal, which is arranged in the target work area of experimental animal production; a work object management subsystem includes an operation information identification and collection module; the work object management subsystem is deployed on a work point, which is arranged in the target work area; a data information management subsystem includes an information transmission module and an information recording module; the task allocation module is used to dispatch the target work task to the target work group; The target work task is associated with the target task operation object and operation steps; the task claiming module is used to enable the staff belonging to the target work group to claim the task after identity authentication through any of the interactive terminals; the task operation guidance module is used to send guidance information to the staff who claim the task through the interactive terminal; the guidance information includes the SOP of each of the operation steps; 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 conduct a consistency review between the actual operation and the SOP based on the operation execution status information, as a condition for releasing the target work task.

[0024] RFID technology uses RFID readers installed at various locations to couple with RFID tags attached to work objects, enabling data collection. In specific implementations, interactive terminals can include mobile interactive terminals that can be moved within the target work area, while fixed interactive terminals can be fixed to the target work location.

[0025] Mobile interactive terminals can be tied to specific staff members through RFID identification technology. For example, each staff member is equipped with a unique ID tag (based on RFID technology). When a staff member wants to use a mobile interactive terminal, they can activate it using their ID tag. The mobile interactive terminal then obtains the staff member's identity information, which serves as the operator account information at that moment to open the mobile interactive terminal.

[0026] Fixed interactive terminals can be installed at each specific work point (or workflow point). The production management system background will assign the day's or immediate work tasks to the corresponding work point and display them on the fixed interactive terminal. When a worker forms a binding relationship with a work point and the corresponding fixed interactive terminal, the system will assign the immediate work tasks of the work point to this worker.

[0027] It should be understood that the interactive terminal is not a necessary module for this system. It can be understood that, due to the characteristics of the experimental animal industry, current technology cannot fully realize unmanned factories, and the execution and operation of some tasks can only be completed manually, so an accompanying input and output device is required. On the contrary, sensors collect data, transmit data, record data, process data, etc., without any human participation, and there is no need for interactive terminals. As technology develops, the basic architecture of this system will not change, but interactive terminals will gradually withdraw from the stage of history. If the interactive terminal is a medium for information interaction between staff members, then there should also be a medium for information interaction with the task object, which is the RFID reader unit in the present invention.

[0028] For workers, RFID identification technology can be used to bind them to specific work areas and work locations. By binding fixed interactive terminals to specific work areas and work locations, and mobile interactive terminals to specific workers, and specific workers to work areas and locations, specific work task information can be assigned to specific work areas, work locations, and specific workers.

[0029] When the task assignment module is operational, it can send target work tasks to specific work areas, locations, and work groups via fixed or mobile interactive terminals installed within the facility (or other more flexible operating devices such as computers or mobile apps located outside the facility). For fixed interactive terminals, their location is defined by the specific physical address code of the work area or location to which they belong.

[0030] When the task operation guidance module is working, it can use the interactive terminals located at each work point to gradually send operation guidance information to the staff who claim the work task after receiving the claim confirmation signal; the system breaks down a work task into several operation steps according to the standard operating procedure (or standard operating procedure) (SOP); through the interactive terminal, the SOP of each operation step is displayed to the staff in the form of text, image or sound.

[0031] The first piece of guidance information might be the specific object being manipulated, such as an animal or cage, including its location. After the worker moves the object to a workbench, an RFID reader installed on the workbench authenticates the object's identity. If authentication succeeds, the task, person, and object are successfully bound, and the guidance proceeds to the next step.

[0032] Regarding the step-by-step sending of operation guidance information, specifically, an operation process may include several operation steps. The specific operation steps and the order of these steps are strictly specified by the SOP. The system can guide and verify the staff to perform operations one by one according to the standard SOP. This is of great help in improving product quality and can minimize inefficiency and quality problems caused by human factors.

[0033] The system of the present invention can capture the signal connection and disconnection status of the RFID tag transponder associated with the operation task, as well as the continuous changes of this status, through the second-class RFID reading and writing device group bound to the work point, and record each change in the production management system; by capturing the changes in the RFID tag status, the production management system can automatically confirm the completion of each step of the operation and send information to the interactive terminal; the confirmation of the completion of each step of the operation by the production management system can trigger the interactive terminal to jump to the output and display of the guidance information of the next SOP operation step. The "automatic confirmation" emphasized here means that it is automatically executed by the system without human intervention.

[0034] The connection and disconnection of RFID tags and RFID readers can reflect whether the object being operated or tracked appears correctly at a specific point in the operation process, thereby preventing errors. In addition, the system records when an object connects to a certain point, when it leaves that point, and how long it takes for it to reappear and connect at the next point. This is used to determine whether there are errors in the operation sequence or whether the standard stay or disconnection time has been exceeded. This also serves as a basic data source for machine learning and system self-determination.

[0035] For environmentally sensitive animals, when removed from the standard living environment provided by the container system, their functions and state may change, affecting the quality of the animal product. If the time spent at a process point exceeds a reasonable range (threshold), production accidents or efficiency issues may occur. For several steps in an operation process, verification is not required. It can be simply understood that the reader captures the connection of a tag, which marks the beginning, and the tag detaches, which marks the end. Tag detachment is the trigger signal for the system to confirm the end. To determine whether "reasonable" is achieved, the system captures several operations in an operation process and comprehensively determines their order, interval time, time spent on each step, and overall duration.

[0036] When the operational information recognition and collection module is operational, it can automatically capture information from operational processes and actions within the overall production process that are valuable for information collection, defining which "objects" are valuable for information collection. RFID tag transponders can be installed on different target tracking objects. During production operations, these RFID tag transponders couple with RFID reader / writer devices installed at different work points and transmit signals to obtain relevant information such as the target tracking object's location and status. 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; and RFID tags can be installed on sensors such as temperature, humidity, weight, and liquid level to collect their status data and location information. The information collected by the collection module can be changes in position, state, quantity, a combination of several changes, or the sequence of several changes. The operational information recognition and collection module primarily relies on RFID readers and has no direct connection to the interactive terminal.

[0037] When the task execution audit module is working, the data collected by the operation information identification and acquisition module can be transmitted to the animal production management system background through the information transmission module, compiled into the execution status of a work task or an operation step, and then compared, judged and fed back with the pre-determined SOP; it can be used to review whether the specific content of the execution operation is consistent with the task assigned by the work task assignment module; it can review whether the operation executor of the task is consistent with the executor confirmed by the task claiming module; it can review whether the operation of the work task is consistent with the steps of the operation guidance module; if there is inconsistency in the review result, a warning message can be promptly sent to the interactive terminal associated with the operation executor, prompting correction; if there is no deviation in the review result, it can automatically enter the next process or operation step. In the present invention, the main steps directly participated by people can only be task assignment → task claiming → obtaining guidance information → task execution. The audit task execution result in the present invention is completed by the system itself, and interacts with the on-site operation process through the information transmission module.

[0038] When implementing specific tasks, the production management system can create a standard work breakdown structure. When breaking down the steps into specific work steps, these steps correspond to the SOP. RFID signal collection isn't directly tied to a specific SOP; it simply records the presence or absence of a worker, or the value provided, in a database. This value can then be used as an input parameter for the system's decision-making algorithm.

[0039] Existing experimental animal production management systems have numerous flaws. Most system hardware is located outside the barrier facilities, relying on manual data entry and lacking direct connection to the frontline processes within the barrier. This makes it impossible to achieve coordination and scheduling between production processes, as well as real-time information updates and feedback. Even some systems have added the ability to scan animal tags using handheld mobile devices, which only links animals to information management systems. Production process data is not effectively collected, transmitted, processed, or fed back. This makes it impossible to coordinate various processes to improve production efficiency and animal quality. Furthermore, animals of different strains, ages, and groups cannot be located. These systems still rely heavily on manual operations, resulting in limited efficiency gains in large-scale production scenarios.

[0040] The present invention utilizes RFID technology to construct a laboratory animal production management system, with each module working closely together. The work task allocation module achieves precise task allocation through precise equipment and personnel binding; the task claim module clarifies task ownership; the operation guidance module automatically guides operations and confirms step completion according to the SOP; the operation information identification and acquisition module comprehensively collects various production process data and captures the operation status; the information transmission module ensures accurate data transmission; the task execution review module ensures that operations meet standards; the information recording module records information throughout the production process; and the task completion module implements closed-loop task management. These modules work together to achieve automated and intelligent management of the production process.

[0041] Traditionally, obtaining work tasks relies on manual verification and recording, making animal location locating difficult and time-consuming. Filling out and updating animal information tags is inconvenient and prone to errors, and the cage replacement process is cumbersome. The system presented in this paper, however, allows workers to access tasks by activating an interactive terminal using an identification tag. The system accurately locates the animal and cage, automatically recording and updating animal information, significantly simplifying the cage replacement process, reducing steps and search time, and improving overall production efficiency. This system monitors the living environment parameters of experimental animals in real time (e.g., temperature and humidity, collected through sensor tags), promptly detecting anomalies and automatically adjusting them to minimize the impact of environmental factors on the animals. The system also monitors the daily consumption of key production materials, such as drinking water and feed, providing prompt reminders for replenishment. Furthermore, standardized operational procedures and review mechanisms reduce human error, ensure the accuracy and reliability of animal experimental data, and thus improve the quality of experimental animals. Automated data collection, transmission, and processing reduce manual operations, lower labor costs, and minimize resource waste caused by manual recording errors and disorganized animal information management, further reducing production and management costs.

[0042] Each module in this invention implements its corresponding functionality through system integration, combining hardware devices and software systems based on specific needs and application scenarios. The hardware requirements primarily include interactive terminal devices (mobile interactive terminals, fixed interactive terminals, etc.), identification and data collection equipment (RFID readers, RFID badges, RFID tags, RFID sensors, etc.), network transmission equipment (routers, switches, etc.), and system backend equipment (servers, database storage devices, etc.). The specific devices used for the interactive terminals can be selected from a variety of options. Fixed interactive terminals can include computers, industrial personal computers, touch-screen computers, etc., while mobile interactive terminals can include mobile phones, tablets, smart watches, etc.

[0043] It should be understood that the "system" in the present invention emphasizes a system process, which ignores the existence of servers and interactive terminals. However, the carrier of the software part, especially the application deployed in the cloud, is most likely composed of a server as its physical carrier. The original intention of this system is to track and identify the operated objects "animals, cages, sensors". By achieving the tracking and identification of the operated objects, the management of production tasks can be achieved. The original intention of data collection is to collect various types of data information of the "operated objects" and indirectly feedback the production status in the factory. For production facilities of different sizes, the hardware carriers will be different during implementation and deployment. It may be the reader-writer device itself, the interactive terminal, a server, a virtual machine based on several servers, or a cloud-based node.

[0044] From the perspective of physical hardware, the core devices and equipment of this system are the RFID tag chips embedded in the operating objects and the RFID reader devices arranged at different working points. Passive and wireless data collection is achieved by relying on these two. The interactive terminal is an auxiliary device that is logically parallel to the RFID reader device. With the development of technology, manual operations will gradually be replaced by more automated mechanical equipment, and the "interactive terminal" will also be reduced until it is eliminated.

[0045] From a more structured perspective, the present invention can be divided into two parts. The first part is associated with the operator performing the operation and can be authenticated and tracked through a 13.56MHz high-frequency (NFC) RFID tag and a first-class RFID reader / writer device. This primarily involves the task assignment module, the task claim module, the task operation guidance module, and the task completion module. The physical carrier of this part can be an interactive terminal. The second part is a module associated with the object being operated on and can be authenticated, tracked, and collected data through an ultra-high frequency (UHF) 920MHz RFID tag installed on the tracked object and a second-class RFID reader / writer device installed at the work point (such as a cage or operating table). This primarily involves the operation information identification and collection module.

[0046] The modules in the first and second parts can communicate with the system backend (e.g., a database) through information transmission modules (information transmission module) and record information (information recording module). Furthermore, the two parts are linked together through "operation execution." Here, a work task is tied to a specific operator and the specific object being operated.

[0047] 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.

[0048] An RFID reader / writer is a terminal computing unit equipped with a single-chip microcomputer. It can be considered a device equivalent to an "interactive terminal." If the interactive terminal is the medium through which workers interact with back-end systems, then the "RFID reader / writer device" is the medium through which the operated object interacts with the back-end system. This device also largely performs computing services for applications. Essentially, depending on the scale of the production facility, the various submodules of the aforementioned system can be deployed on the reader / writer unit for stand-alone use; on the interactive terminal, treating the interactive terminal as a computer and providing services for small-scale, localized facilities; on the server side or on a virtual machine generated by the server, providing services for large-scale, cross-regional facilities; or on a combination of one or more of the aforementioned devices for collaborative computing and service provision.

[0049] Simply put, 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 can automatically collect, transmit, and process passive and wireless data within laboratory animal facilities, enabling more efficient and accurate task allocation, execution, and supervision. This improves production efficiency, reduces costs, and promotes lean production in the laboratory animal industry.

[0050] This invention leverages RFID technology. By deploying a large number of RFID readers and writers within animal facilities, it tracks, locates, and identifies the status of key production objects (cages, animals, sensors, etc.) equipped with RFID tags, thereby enabling passive, wireless collection, transmission, and recording of production data. This technology offers the advantage of virtually eliminating the need for human intervention in data collection, transmission, and recording, significantly improving the efficiency of information acquisition, transmission, and recording. This reduces the probability of errors caused by operational uncertainty, lowers overall production costs, and improves yield rates. Furthermore, production data collected using RFID technology can serve as a data source for machine learning and artificial intelligence, providing a foundation for self-determination in production lines.

[0051] In a specific embodiment of the present invention, each target work task has a unique task code, and the task code includes target work area information, work point 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; The task assignment module performs the following steps when distributing the target work task: the task assignment module distributes the target work task with a unique task code to the interactive terminal through the information transmission module.

[0052] The target task object information is the core of the work task. The system automatically generates and returns its location information based on this target task object information. For example, a customer places an order, which includes the desired animal breed, quantity, and animal characteristics such as sex, age, and weight. Upon receiving this order, the production management system searches the system for animals in stock that meet the requirement, or for animals that can be delivered in batches within a certain period of time. This search process is performed using RFID readers and RFID tags attached to animal cages or animals. Based on the search results, a work order is automatically generated for the production workshop (for example, a work order to select and cage animals that meet the requirements, or to box and ship animals that meet the requirements). This production work order is then split into several sub-orders and sent to different workspaces to ensure that the animals that meet the requirements can be delivered to the customer as quickly as possible. Therefore, the order generation and dispatch process begins with the location of the animal products, followed by the target workspace and workstation information. The location information of animal products that meet the requirements, or will meet the requirements in the short term, is generated instantly after data collection and confirmation through RFID readers and RFID tags installed on animal cages / animals. Due to the particularity of the experimental animal industry, each work area basically has a unique and fixed corresponding work group, and the work groups and personnel in different work areas cannot overlap. However, who performs this operation in each corresponding work group is not unique. For the identification of staff, it does not mean that this work task must be assigned to a certain person, but it is necessary to record who specifically performs this work task. (If cross-infection occurs between animals, the operator is most likely to become a carrier of these microorganisms) In a specific embodiment of the present invention, each staff member of the target work group is equipped with a unique RFID badge, each of which stores a unique staff member identity code. The staff member identity code is used for staff member identity verification, and the verification items include determining whether the staff member belongs to the target work group; Each of the interactive terminals is embedded with a first-class RFID reader / writer device, and each of the interactive terminals has a unique first-class device code, which includes the unique location information of the interactive terminal; the first-class RFID reader / writer device can call the staff information collection module; and the interactive terminal can call the task claiming module; The task claiming module performs the following steps when claiming a task: The staff information collection module collects the staff identity code from the RFID work badge through the first type of RFID reader / writer device; the task claiming module obtains the staff identity code from the staff information collection module; if the staff identity code belongs to the target work group and has the authority or qualifications to perform the target work task, the confirmation task claim information is presented on the interactive terminal, and the staff clicks the confirmation button on the interactive terminal, and the system background binds the task code and the staff identity code.

[0053] The interactive terminal can be thought of as a public (shared) input and output device. Once the personnel's identity and work task information are confirmed, this information is temporarily stored in a location. When the RFID tag chip of the object being operated (cage, animal) is recognized and captured by a second-class RFID reader / writer located at the operator's station, the work task, personnel, and object are linked together for easy traceability. A single work task might involve operating cages 1 through 10, but each time a cage is operated, a link is created to record the specific time information.

[0054] The core purpose of task claiming is to identify which worker, at what location, and what work has been claimed. The device code on the interactive terminal is not the key factor; the specific work location indicated on the interactive terminal is the core traceability information. When the task claiming module is operational, a specific worker can use the touch input function of the interactive terminal (preferably a fixed interactive terminal, as mobile interactive terminals can be inconvenient to charge and sterilize, and moving a device around a clean facility can also pose a risk of contamination. Therefore, the use of mobile devices should be avoided as much as possible. However, mobile interactive terminals can be used in some inconvenient scenarios) to claim and confirm the assigned work task, thereby determining ownership of the task. The interactive terminal obtains the specific work task code from the production management system through the information transmission module. The interactive terminal's RFID reader / writer reads the worker's RFID tag to obtain detailed worker information. A specific worker who has been identified and meets the assignment criteria can click the "Confirm" button on the interactive terminal to associate the work task code with the worker's identification code, confirming the assignment of the task to the specific worker and establishing ownership. This association information is then sent to the production management system backend through the interactive terminal's information transmission module.

[0055] Specifically, the target work area information can include the device codes of interactive terminals that meet the requirements of this target work task, the target work point information can include the location codes of fixed interactive terminals involved in this target work, and the target work group information can include the identity codes of staff members that meet the requirements of this target work task. More specifically, there can be only one or more mobile interactive devices that meet the requirements, and the staff member can choose any one of them. There can be only one or more fixed interactive devices that meet the requirements. For example, a cage changing operation involves two work points: the cage rack and the cage changing workbench, that is, two fixed interactive devices. There can be only one or more staff members that meet the requirements, and any one of the multiple people in the work group can claim the task.

[0056] Regarding task claiming, it can be a manual operation or the task code can be automatically obtained. For example, when the staff enters the work area, the mobile interactive terminal is turned on and prompts the staff to claim the work, or the staff turns on the mobile interactive terminal after entering the work area, enters the task claiming page, and then selects the work that can be claimed.

[0057] 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, and the target task operation object code is used to identify the target task operation object; Each of the work points is equipped with a second-class RFID reader / writer device, each of which has a unique second-class device code, which includes the unique location information of the second-class RFID reader / writer device; the second-class RFID reader / writer device can call the operation information identification and collection module; the operation information identification and collection module obtains the target task operation object code from the RFID tag transponder through the second-class RFID reader / writer device to capture the operation execution status information, and binds the task code, the staff identity code and the target task operation object code; The operation information identification and collection module performs the following steps when capturing the operation execution status information: The operation information identification and collection module captures the operation execution status information according to the target work task and the connection and disconnection status information; The access and disconnection status information is generated by the second type RFID reader / writer device monitoring the access and disconnection status of the RFID tag transponder.

[0058] Each product, task, or operation object is assigned a unique identity. RFID technology is used to collect data on their location within the work area, as well as their workflow, process, and points, including sensor status data. This automatically collected data (AIDC) serves as raw data for machine learning. The machine learning results, when returned to the frontline production workshop, can guide actual operations, thereby achieving a more lean production process.

[0059] In specific implementations, for example, a second-class RFID reader / writer device can actively poll the RFID tag transponder of the target task object, transmitting a radio frequency signal every 500 milliseconds. When the tag enters the reader's effective recognition range (e.g., a 2-cm radius), it is activated and returns a signal. The reader / writer records information such as the tag connection time and signal strength. When the tag leaves the recognition range, the reader / writer records the disconnection time. The second-class RFID reader / writer device can transmit this connection and disconnection information to the system backend via an information transmission module. For example, in an animal transfer task, if the reader / writer detects that the tag of the container containing the experimental animal has disconnected at the source location and connected at the target location, and the time interval falls within 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. This operation execution status information can be stored in the system backend database, using the task code and operation step identifier as a joint primary key.

[0060] The existing technology relies heavily on manual recording when capturing the status of operation execution, and is unable to obtain operation status information in real time and accurately. The present invention utilizes the access and disconnection information of RFID tags to generate operation execution status information, achieving real-time and automatic monitoring of the operation process, and accurately judging the completion status of the operation steps. In the production process of experimental animals, accurately grasping the operation execution status is crucial to ensuring production quality and efficiency. The solution of the present invention can promptly detect abnormal conditions in the operation, such as missing operation steps, excessive operation time, etc. For example, during the animal breeding process, if the cage changing operation time exceeds the normal range, the system can promptly issue an alarm to remind the staff to check the work point or the animal status. By accurately monitoring the operation status, animal health problems and production accidents caused by improper operation are effectively avoided, and the lean level of production management is improved.

[0061] For example, consider the laboratory animal cage replacement scenario: the target task is to replace a cage. When a worker removes a cage containing an animal from its original cage rack, an RFID reader mounted on the cage rack detects the disconnection information on the cage's RFID tag. This information is transmitted to the system backend via the information transmission module. Based on the target task, the backend determines that this may be the beginning of the "removal of the cage from the original cage rack" step in the cage replacement operation. When the worker places the cage on the cage replacement workstation, the RFID reader on the workstation detects the access information on the cage tag and transmits it to the system backend. Based on the task flow, the system determines that the "removal of the cage from the original cage rack and placement on the cage replacement workstation" step has been completed. If the corresponding access or disconnection information is not detected within a specified time (for example, 3 minutes, whichever is appropriate based on actual operation), the system determines that the operation is abnormal and the current step has not been completed normally.

[0062] In a specific embodiment of the present invention, the interactive terminal may further call the task completion module; the task completion module is used to enable the task claiming staff to release the task through the interactive terminal after the staff claiming the task completes the target work task and the actual operation passes the review of the task execution review module; The task completion module performs the following steps when releasing the target work task: The staff information collection module collects the staff identity code from the RFID work badge through the first type of RFID reader device; the task completion module obtains the staff identity code from the staff information collection module; if the staff identity code and the task code are in a bound state, and the audit result of the task execution audit module is "passed the audit", the confirmation task release information is presented on the interactive terminal, and the staff clicks the confirmation button on the interactive terminal, and the system background releases the binding relationship between the task code, the staff identity code and the target task operation object code.

[0063] When the Task Completion module is active, all operations for a task are completed and reviewed, and all relevant information is recorded in the animal production management system database. The staff member then unbinds the Task Assignment module and waits to receive the next task assignment. Regarding task release, this interface can be set to appear only after all tasks are completed and all steps have passed consistency review. It can also be set to allow release midway to handle unexpected situations.

[0064] In specific implementation, for example, each target work task can be assigned a unique task code. This code can be generated using a combination of a timestamp, work type code, and serial number. For example, "20241001001001" represents the date, the middle three digits represent the work type, and the last three digits are the serial number for that type of work performed that day. Each worker is equipped with a unique RFID badge, whose identification code is stored in the chip. Each interactive terminal has a unique device code, which is burned into the device during production. The task code includes information about the target work area, target work point, and target work group. For example, "01-05-03" represents work area 1, work point 5, and work group 3, respectively. When a worker claims a task through an interactive terminal, the interactive terminal's information transmission module sends a request to the system backend to obtain the task code. After verifying the legitimacy of the interactive terminal, the system backend returns the task code in JSON format. The RFID reader uses a 13.56MHz frequency to read the RFID badge ID code and compares the read worker ID code with the target workgroup information in the task code. If a match occurs, the interactive terminal screen displays a pop-up window confirming task claim, which includes task details (task name, estimated duration, etc.). The worker clicks the confirm button, and the interactive terminal sends the task code and worker 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 worker releases the task through the interactive terminal, the RFID reader reads the badge ID code again and queries the database table. If the worker ID code and task code are already bound, the interactive terminal displays confirmation of task release, which may include a brief summary of the task completion status (completed steps, unfinished steps, etc.). The worker clicks the confirm button, and the system backend deletes the corresponding binding record from the database table, releasing the binding relationship.

[0065] In the prior art, task claiming and release methods mostly rely on manual registration or simple account and password verification, lacking close links with personnel and equipment and automated processes. The present invention, through a unique coding system and RFID technology, can achieve precise binding and release of tasks, personnel, and equipment, not only improving the accuracy and efficiency of task management, but also enhancing traceability. This task claiming and release method based on coding and RFID technology is a completely new design approach compared to traditional methods. In the experimental animal production management scenario, traditional task claiming and release methods are prone to problems such as mismatch between personnel and tasks and difficulty in tracking task progress. The solution of the present invention realizes the automatic allocation and precise association of tasks. When personnel transfers or task adjustments occur, the system can respond quickly and reallocate tasks. For example, if the staff member originally responsible for the animal feeding task in area A has something to do temporarily, the system can quickly reallocate the task to other personnel in the same team and can accurately record the task flow process. At the same time, through the binding relationship, the executors and equipment usage of each task can be viewed in real time, facilitating management and supervision, which is difficult to achieve with traditional methods.

[0066] In a specific embodiment of the present invention, the task operation guidance module performs the following steps when sending the guidance information: The task operation guidance module obtains the operation execution status information from the operation information identification and collection module, determines the guidance information that should be sent for the current operation step based on the operation execution status information, and presents the guidance information of the current operation step to the staff in the form of text, image or sound through the interactive terminal.

[0067] In specific implementations, for example, the system backend can push operation execution status information to a fixed interactive terminal in real time. Upon receiving the information, the fixed interactive terminal parses the operation step identifier (e.g., "step001," "step002," etc.) and task progress information (number of completed steps, duration of the current step, etc.). Based on a pre-set guidance information mapping table, the guidance information that should be sent for the current operation step is determined. Guidance information can be stored in a local database on the fixed interactive terminal, indexed by the operation step identifier as the primary key. The fixed interactive terminal presents guidance information to the staff member in the form of text, images, or audio. If presented in text form, detailed instructions can be displayed in a specific area of the interactive terminal screen (e.g., the bottom information bar). If presented in image form, images of the corresponding operation steps can be retrieved from a locally stored image library, with key operational points annotated on the images. If presented in audio form, pre-recorded voice guidance content can be played by invoking the interactive terminal's audio playback interface, containing the operation steps, precautions, and so on.

[0068] In the prior art, operation guidance mostly provides all the operation instructions at once or a simple paper guide, which cannot provide real-time guidance according to the progress of the operation. The present invention dynamically sends guidance information based on the operation execution status information, and provides a variety of display forms, realizing personalized and precise operation guidance. In the production operation of experimental animals, the complex operation process and high-standard specification requirements make operators prone to errors. The dynamic guidance system of the present invention significantly improves the work accuracy and efficiency of the operators. For example, when performing experimental animal surgery, the operator can accurately complete the surgical process according to the real-time guidance of each step, reducing animal casualties and experimental failures caused by operational errors. At the same time, a variety of display forms meet the learning and operation habits of different operators, and improve the convenience of operation.

[0069] In a specific embodiment of the present invention, the target task operation object includes an experimental animal and / or an animal container and / or a sensor; the sensor includes a temperature sensor and / or a humidity sensor and / or a weight sensor and / or a liquid level sensor and / or a pressure sensor; the experimental animal is equipped with a first-class RFID tag transponder, the animal container is equipped with a second-class RFID tag transponder, and the sensor is equipped with a third-class RFID tag transponder; The operation information identification and collection module performs the following steps when collecting the operation execution status information: The operation information identification and collection module reads the first type of RFID tag transponder through the second type of RFID reader / writer device to collect the identity information and location information of the experimental animal; and / or, the operation information identification and collection module reads the second type of RFID tag transponder through the second type of RFID reader / writer device to collect the identity information and location information of the animal container; and / or, the operation information identification and collection 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.

[0070] Temperature sensor: It can be used to monitor the temperature of the environment in which experimental animals live in real time. Experimental animals have strict requirements on the temperature of their living environment. Temperatures that are too high or too low may interfere with the normal physiological functions of the animals and affect the accuracy of experimental data. Taking mice as an example, their suitable living temperature is usually 22℃±2℃. The temperature sensor continuously collects temperature data and transmits it to the system background with the help of RFID tags. Once the temperature exceeds the preset reasonable range, the system will immediately issue an alarm and automatically adjust it (experimental animal facilities require constant temperature and humidity 24 hours a day, 365 days a year, and the fluctuation range of the standard value is very small, so only an automatic adjustment control mechanism can be used to ensure that the animals live in a suitable temperature environment and ensure the smooth progress of the experiment.

[0071] Humidity sensors monitor the humidity of the laboratory animal environment. Humidity significantly impacts the health of laboratory animals. High humidity can easily breed bacteria and fungi, leading to illness. Low humidity can dry out the air and cause respiratory problems. For example, when raising mice, the ideal humidity level is typically between 40% and 70%. Humidity sensors monitor humidity in real time and upload data. The system uses this data to determine whether humidity is appropriate. If any abnormalities are detected, the system automatically adjusts the humidity to maintain a stable humidity environment for the animals.

[0072] Weight sensors can be used to measure the weight of experimental animals or supplies such as feed and drinking water. Measuring the weight of experimental animals and uploading it to the production management system via RFID tags and readers facilitates rapid animal selection. In drug trials, ensuring that animal weight meets standards is a key indicator for ensuring efficacy. Furthermore, by monitoring changes in feed and drinking water weight, we can monitor animal eating and drinking habits, assess their health, and promptly alert staff to replenish supplies, preventing shortages that could impact animal growth and experimental progress.

[0073] Liquid level sensors can be used to monitor the liquid level in animal drinking water containers or other liquid containers. When raising experimental animals, ensuring that animals have sufficient clean drinking water at all times is crucial. Liquid level sensors monitor the water level in real time. When the liquid level falls below the set threshold, the system promptly issues a prompt, notifying staff to add water to ensure the animals' normal drinking needs. In some special experimental scenarios, where precise control of liquid usage is required, liquid level sensors can also provide accurate data support for experimental operations.

[0074] In specific implementations, for example, RFID tags for experimental animals can be implanted subcutaneously or in the form of ear tags. The tag chip stores the animal's identity information (identity information is a unique identification code that serves as a database key, linking the animal's strain information, genetic information, date of birth, etc.) and location information (location information is assigned by the RFID reader / writer's location code; when object A is captured and identified by reader / writer X, object A is considered to be within the location area of X). For example, a mouse numbered "001" has its tag stored with the identity 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 container surface, either adhesively or embedded. The tags store the container's identity information (such as container type, number, and region) and location information (also obtained through communication with the RFID reader / writer). For example, a mouse cage numbered "V005" has a tag that stores the identity information "MouseCage-V005-A01," indicating mouse cage number 5 in area A01. A sensor's RFID tag is integrated within the sensor. For example, a temperature sensor not only stores sensor identification information (such as manufacturer, model, and serial number), but also collects and stores real-time temperature measurement data (with an accuracy of ±0.1°C) and location information. The sensor writes measurement data into the tag in a specific format (e.g., JSON format: {"sensor_id":"T001","temperature":"22.5","location":"X:15.0,Y:8.0,Z:1.0"}). The tag then transmits this information to the RFID reader / writer on the interactive terminal via radio frequency signals.

[0075] In the prior art, the information collection methods for experimental animals, animal containers and sensors are relatively simple, and unified management and real-time tracking cannot be achieved (real-time tracking and positioning can be defined as a function of the data acquisition module, which collects the location information of the operating object). The present invention realizes the integrated management of identity recognition, location tracking and data collection of multiple objects by installing RFID tags on different target tracking objects. In the production management of experimental animals, comprehensive and real-time information collection is crucial to ensure animal health and experimental accuracy. The solution of the present invention realizes all-round monitoring of the living environment and the status of experimental animals. For example, through temperature and humidity sensor tags, the temperature and humidity changes of the animal breeding environment can be monitored in real time. When the environmental parameters exceed the appropriate range, the system automatically issues an alarm to remind the staff to adjust the environmental conditions. At the same time, by tracking the location of animal containers and animals, it is convenient for staff to quickly find and manage, thereby improving work efficiency. These effects are difficult to achieve with traditional information collection methods.

[0076] In a specific embodiment of the present invention, the task execution audit module includes the following steps when performing the consistency audit between the actual operation and the SOP: Review whether the specific task operation object of the actual operation is consistent with the target task operation object; and / or, review whether the specific content of the actual operation is consistent with the target work task; and / or, review whether the operation steps of the actual operation are consistent with the guidance information.

[0077] A key aspect of the task execution review module is to avoid confusion about the objects being operated on. For example, if the animals in a certain numbered cage are being weaned (after three weeks of weaning, the pups are separated from their mothers and moved to the rearing stage), the traditional work model lacks automated mechanisms for digital identification, comparison, and review. This often leads to the wrong cage being used, such as incorrectly weaning a newly born animal in its weaning stage. This is a surefire workplace accident and can result in losses. The task execution review module of the present invention can effectively mitigate this risk.

[0078] During implementation, to verify whether the specific content / object of the actual operation aligns with the target work task / object assigned by the task assignment module, the system backend retrieves task assignment information from the task management database, including task type (e.g., adding feed to animals, changing cages), task details (feed amount, operation steps, etc.), and specific task object. Information collected during the actual operation (e.g., feeding amount recorded during feeding operations, execution of operation steps recorded during cage changing operations) is compared with the task assignment information. To verify whether the actual operator is the same as the one who claimed the task in the task claim module, the system backend retrieves the operator identity code associated with the task claim from the task claim record database and compares it with the operator identity code obtained through the interactive terminal during the operation (obtained by reading the RFID badge). If the two match, the operator is deemed qualified. In this operation scenario, the interactive terminal is installed in two locations: one on the cage rack and the other on the operating table. The interactive terminal on the cage rack will tell you which cage box to take out. The identity authentication process at this time will record who took out the cage box (due to the requirements of sterility and cleanliness, the personnel who transport the cage boxes and the operators are usually separated to avoid frequent disinfection processes). After that, the step of taking out 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 to record who performed the operation task for this cage box.

[0079] When reviewing whether the actual operation steps are consistent with the guidance information sent by the operation guidance module, the system background can record each step of the guidance information sent by the operation guidance module (including the time and content of the guidance information), and also record the steps and time the operator actually performed the operation. For example, in the laboratory animal screening operation, the operation guidance module sends the guidance information of screening operation steps 1 and step 2 in sequence. The system compares the order and time of the steps actually performed by the operator to determine whether they are consistent with the guidance information. If there is any inconsistency, the system will record the difference in detail (such as skipped steps, steps executed in the wrong order, etc.).

[0080] In terms of operational audits, the existing technologies mostly rely on manual periodic inspections or simple post-verifications, which are inefficient and prone to omissions. The present invention has constructed a comprehensive and automatic consistency audit mechanism, which performs real-time audits from four dimensions: operation content, operation object, operator and operation steps. Compared with traditional audit technologies, this multi-dimensional and automated audit method has significantly improved the comprehensiveness, accuracy and timeliness of the audit. In the production process of experimental animals, ensuring the consistency of operations is crucial to ensuring the reliability of experimental results and the quality of animals. The consistency audit mechanism of the present invention effectively reduces operational errors and violations. Strict audits of operating steps avoid experimental failures and animal waste due to improper operation, and improve the success rate of experiments and the utilization rate of animal resources. At the same time, the real-time audit function enables problems to be discovered and corrected in a timely manner, reducing the potential risks brought about by incorrect operations.

[0081] In a specific embodiment of the present invention, if the consistency review fails, the system background sends a warning message to the interactive terminal bound to the target work task; if the consistency review passes, the fixed interactive terminal starts sending guidance information for the next step.

[0082] In specific implementation, for example, if the consistency review fails, the system backend retrieves information about the interactive terminals associated with the target work task (from the task assignment record database) based on the task code, including the device codes and network addresses of mobile and fixed interactive terminals. The system backend then sends warning messages to these interactive terminals via a network push service (such as Jiguang Push). This warning message appears on the interactive terminal screen in a pop-up window titled "Operation Abnormality Alert" and details the abnormality (e.g., "Operation Step Error: Step 3 Should Be Performed After Step 2" or "Operation Object Inconsistency: Current Operation Object is XXX, Expected to be XXX"), along with a link to the correct operating procedures and standards. If the consistency review passes, the fixed interactive terminal retrieves guidance information for the next step from the guidance information database. The guidance information database stores guidance information in sequential order of operation steps, with each guidance information record containing fields such as step number, guidance content, and presentation format. Based on the current operation step number, the fixed interactive terminal retrieves the guidance information corresponding to the next step number and presents it to the staff member in the specified presentation format (text, image, or audio).

[0083] The existing technology lacks a timely and effective warning mechanism when dealing with inconsistent operations, and the consistency and standardization of the operating process are difficult to ensure. The present invention designs precise warning and guidance measures for the consistency audit results. Through timely warning information and automatic push of next step guidance information, dynamic management and optimization of the operating process are achieved. In the experimental animal production management scenario, it is crucial to correct operational errors in a timely manner and guide the correct operating process. The solution of the present invention can effectively avoid subsequent problems caused by the failure to discover operational errors in a timely manner, such as experimental failure, damage to animal health, etc. For example, in the in vivo efficacy test experiment, once an operational step error is discovered 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 work consistency and efficiency of the operator, an effect that is difficult to achieve with traditional operation management methods.

[0084] When the information transmission module is operating, the signal of the target tracking object received by the RFID tag is sent to the RFID reader 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 through the information transmission module. For RFID tags that only perform identity information recognition, the unique identification code is compiled and transmitted to the RFID reader device via a carrier wave. After receiving the signal from the RFID tag, the RFID reader device demodulates and translates it into digital information, which is then transmitted to the animal production management system backend via the network module. The target tracking object can be a container, an animal, changes in temperature and humidity, feed and drinking water consumption, or any other event in the production process that is valuable for data collection.

[0085] In a specific embodiment of the present invention, the information recording module is used to record the information flow generated by the task assignment module, the task claim 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.

[0086] In specific implementations, for example, when the task assignment module executes a task assignment, the information recording module records the time of the task assignment (accurate to the millisecond, using the system timestamp), location (work area and work location information parsed from the task code), operator identity (obtained from the operator's RFID badge ID code from the interactive terminal performing the task assignment), and specific content of the task assignment (task code, task details, etc.). This information is stored in the "task_assignment_log" table of the system's MySQL database in a structured data format (e.g., JSON format: {"time":"20241010101010.123","location":"A01-05","operator_id":"001","task_assignment":"{...}"}). In the task claiming module, the time, location, operator identity, and confirmation information (task code, confirmation time, etc.) of the task claim are recorded and stored in the "task_claim_log" table. In the operation guidance module, the time, location, operator identity, guidance information content, and the code of the interactive terminal device receiving the guidance information are recorded and stored in the "operation_guidance_log" table. In the operation information identification and collection module, the time series information of the 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 collected information content (animal identity information, container location information, sensor data, etc.) of the target tracking object information 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 transmitted information content of the information transmission 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, fail), and reason for audit failure (inconsistent operation content, inconsistent operator, inconsistent operation steps, and other detailed information) are recorded and stored in the "task_execution_audit_log" table.

[0087] The information records in the production management process of experimental animals in the existing technology are often incomplete, non-standard, lacking in systematicness and relevance. The information recording module of the present invention comprehensively and systematically records the information flow of each link in production management and establishes a complete log system. Through a unified recording format and an associated database table structure, efficient storage and query of information are achieved. In the production management of experimental animals, complete information records are crucial for tracing the production process, analyzing problems and optimizing processes. The information recording module of the present invention provides detailed data support for production management. For example, when an experimental animal has a health problem, the source of the problem can be quickly traced and possible causes (such as improper operation, environmental changes, etc.) can be analyzed by querying operation execution records, environmental monitoring data records, etc. At the same time, by analyzing a large amount of recorded data, bottlenecks and optimization points in the production process can be discovered, and production efficiency and quality can be improved. These effects exceed the level that can be achieved by traditional information recording methods.

[0088] In a 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 staff member and the interactive terminal; and / or binding information between the staff member and the target work area or work point; and / or binding information between the staff member and the target work task; and / or information triggered by the staff member's operation action; and / or consistency review result information.

[0089] When the information recording module is working, it can be executed synchronously with each process in the task assignment module, task claim module, task operation guidance module, operation information collection module, task completion module, information transmission module and task execution review module, and record the information flow generated in each process module in the database of the animal production management system; it can be used to record the binding information between specific staff and mobile interactive terminals, the binding information between staff and work areas and work points, the binding information between staff and work tasks, the binding information between staff and operation objects, etc. in the work task assignment module; record the confirmation feedback information of the staff in the task claim module; record the information triggered by each operation action in the operation information identification and collection module; record each audit result information in the task execution review module; each of the above recorded information includes at least four basic attributes: time attribute, location attribute, operator identity attribute and operation object identity attribute.

[0090] In specific implementations, for example, the time attribute contained in each piece of information recorded by the information recording module is accurate to the second, obtained through the system clock. For example, "20241115142330" represents 14:23:30 on November 15, 2024, ensuring accurate traceability of the moment the operation occurred. Location attributes can be determined based on the work area and work point information in the task code. This information is combined with a positioning module (such as one based on Wi-Fi, Bluetooth, or RFID) to obtain real-time location information. Positioning accuracy can reach tens to dozens of centimeters indoors, and is converted into a corresponding work area identifier. Operator identity attributes are obtained from the RFID badge ID code read by the interactive terminal. This ID code is linked to the personnel information database, allowing queries to retrieve detailed information such as the operator's name and department. For the recorded binding information between staff members and interactive terminals, the information recording module records the binding time, interactive terminal device code, staff member identity code, and the work area and location information where the binding occurs when the staff member uses the interactive terminal to claim or operate a task. For example, if staff member "001" uses the mobile interactive terminal numbered "T005" at work location "A02-03" at "20241115142000" to claim the task, this binding information will be recorded in detail. For the binding information between staff members and work areas and work locations, the binding relationship and effective time are recorded in combination with the staff member identity 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". The binding information between staff members, work tasks, and work objects can be recorded after the task is successfully claimed, including the task code, staff member identity code, claim time, and estimated completion time. For example, if staff member "003" claims task "0002" at "20241115143500" and is expected to be completed at "20241115160000," this information will be accurately recorded. Information triggered by staff members' operational actions can be recorded after the operational information recognition and acquisition module captures the action. For example, during the feed addition operation for experimental animals, if the RFID reader / writer device on the operating table recognizes the label of the feed container and the label of a cage, and the current task assignment module assigns the scenario to feed addition, it is considered a feed addition operation trigger, and the operation time, the object being operated (cage code, animal code, feed batch code, etc.), and the operation location information will be recorded. The result information of the consistency audit can be recorded after the task execution audit module completes the audit; record the audit time, audit results ("pass" or "fail"), and if failed, record the reasons for failure in detail (such as "the actual operation steps do not conform to the SOP, the order of steps 2 and 3 is reversed"), the coding of the operated objects involved, and other information.

[0091] In terms of information recording, the existing technology usually only focuses on key business data, ignores the associated information during the operation, and the recording method is scattered, lacking systematicity and relevance. The information recording module of the present invention not only records various types of operation-related information in detail, but also closely associates multi-dimensional information such as time, place, operator, and operated object with business operations. This comprehensive and associated information recording method breaks the traditional recording mode, builds a complete operation information chain, and provides a rich data foundation for subsequent data analysis, process tracing and optimization. In the field of experimental animal production management, the technical effect brought about by the information recording module of the present invention exceeds conventional expectations. By recording multi-dimensional associated information, when abnormal conditions occur in experimental animals or experimental results deviate, the entire process can be traced quickly and accurately. For example, if a batch of experimental animals is in poor growth condition, a comprehensive analysis can be conducted from multiple aspects such as feed addition records, environmental monitoring records, and experimental operation records based on information such as time, place, and operator to accurately locate the problem, such as whether a certain operator operated improperly at a specific time and place, or whether it was affected by abnormal fluctuations in environmental factors. At the same time, this rich data can also 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, thereby improving overall production efficiency and quality. These in-depth analyses and optimization effects are difficult to achieve through traditional scattered information recording methods.

[0092] like Figure 1 As shown, the present invention also provides a management method for an experimental animal production management system based on RFID technology, comprising the following steps: The target work task is sent to the interactive terminal through the task allocation module; the staff belonging to the target work group is enabled to claim the task through the interactive terminal, thereby binding the task code and the staff identity code; the task code, the staff identity code and the target task operation object code are bound through the second type of RFID reader-writer device; the interactive terminal gradually sends guidance information to the staff so that the staff can perform the work task operation according to the guidance information; the operation information recognition and collection module captures the staff's operation execution status information 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 conducts consistency review on the operation execution status information and the decomposition step information 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 is enabled to release the task through the interactive terminal to release the binding of the task code, the staff identity code and the target task operation object.

[0093] Existing methods for managing laboratory animal production often rely on manual operations and record-keeping, resulting in untimely information transfer and error-prone outcomes. For example, traditional task assignments may be communicated verbally or through paper documents, leading to unclear assignments and confusion among personnel about their assigned tasks. During task execution, there is a lack of real-time operational guidance and monitoring, forcing personnel to rely on memory or paper operating instructions, resulting in low accuracy and efficiency. Information collection and review during operations is often done manually after the fact, preventing timely detection and correction of errors, leading to low production efficiency, unstable animal quality, and high management costs. The present management method, based on RFID and a digital system, automates and digitizes the entire process of task assignment, claiming, execution, review, and release. A unique system of task, identity, and equipment codes ensures precise association of tasks with 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 execution status. A consistent audit mechanism is established to detect and correct operational errors in real time. This fully automated, digitized management approach represents a significant advancement over traditional management methods, both in terms of management model and technical means.

[0094] In order for those skilled in the art to more clearly understand the beneficial technical effects of the present invention, several process steps that can be optimized by adopting the technical solution of the present invention are listed below: 1. Obtaining work tasks Obtaining work assignments is often the first task performed upon entering a barrier facility. Traditionally, work assignments are posted on the barrier's glass windows. Upon entering, workers can look through the windows to obtain their work assignments for the day or the current time period. This window serves as the primary medium of communication between those inside and outside the barrier facility. Currently, a large number of facilities still utilize this method.

[0095] With technological advancements, some facilities have installed computer terminals within their barriers, allowing each barrier area to share a single terminal. Once inside, workers can use the computer terminals to communicate with those outside the barrier. However, even with this approach, the information on the computer terminals still needs to be transferred or the completed work items must be entered onto the computer terminals. The difference between this and the previous approach is that the information is read from a computer screen instead of a glass window, but it does not fundamentally change the way workers communicate information.

[0096] With this invention, the workflows for acquiring work tasks using the two aforementioned methods are essentially eliminated. Upon entering the facility, workers use their ID badges to activate interactive terminals installed at each workflow point, obtaining corresponding work task information. Work execution status and results no longer require manual recording and transmission; instead, RFID tags and readers automatically record the information into the production management system's database.

[0097] 2. Finding the location of animals Traditionally, cage and box layouts are planned in advance. Different animals are placed in essentially fixed areas, cages, and cages, similar to library management, to facilitate easy access for staff. Staff must navigate the predefined space, navigate the correct areas, and select the correct cages to locate the animals they need to work on. However, this approach often limits the placement of cages, as animals from different areas cannot be placed together. When an area is understocked, production resources are left idle. Conversely, when one area is fully occupied, other controlled areas cannot be used, as this would create confusion.

[0098] The system of the present invention can track specific cages and animals. Therefore, a cage filled with animals can be placed freely on a cage rack in any area. The RFID-based production management system will inform workers (for example, by displaying relevant information on the interactive terminal display) where to obtain the task object for this operation. It can also use the principle of proximity to assign tasks based on the relationship between workflow points and the layout of the cage racks, reducing the distance and time required to travel back and forth between the workstation (work point) and the cage racks. More importantly, workers are unlikely to misplace the task object, and even if an error occurs, the system will provide an immediate warning, greatly improving production efficiency and accuracy.

[0099] 3. Filling out and updating animal information plates Traditionally, animal information signs are handwritten and hung on cages for easy access by staff. However, errors often occur due to late or forgotten updates, poor handwriting leading to misreading, and even signs being hung on the wrong cages. Because facility staff are required to wear protective clothing, goggles, and gloves, writing is extremely inconvenient, and staff often find themselves unable to read their own handwriting.

[0100] This system invention disrupts traditional methods of information recording and transmission, eliminating the traditional steps involved. Based on this system, information is recorded seamlessly in a database for each operational process. Simply by clicking a few basic confirmation buttons on an interactive terminal, animal information signs are automatically generated and updated in real time. Physical hanging systems are eliminated, with all information accessed through the interactive terminal. This minimizes the impact of information exchange issues on production costs, quality, and efficiency.

[0101] 4. Cage replacement like Figure 2 As shown in the figure, the traditional cage box replacement operation process includes at least (1) entering the facility, (2) obtaining work information, (3) finding the work object, (4) taking out the cage box, (5) finding the cage changing workbench, (6) cage changing operation, (7) recording work information, (8) returning the cage box to its original position, (9) taking the work record out of the barrier, (10) organizing the information, and (11) entering the system, a total of 11 work steps, involving 2 work points (cage rack, cage changing workbench) and 4 operators.

[0102] like Figure 3 As shown, the cage-changing workflow based on the system of the present invention only requires (1) entering the facility, (2) obtaining information and removing the cage box, (3) cage-changing operation, (4) returning the cage box to its original position, and (5) leaving the facility, a total of five operation steps. Based on the present invention, the work of obtaining, recording, and transmitting information is synchronized with the operation and automatically completed by the RFID device and production management system; the recording, transmission, and verification of work information are all automatic and imperceptible; because the mobile interactive terminal and the fixed interactive terminal can receive and present the target work task information, the location of the cage box and the work point to be visited (such as the cage-changing workbench) can be quickly and clearly prompted to the staff, thereby greatly saving the time and energy spent on finding the work object, finding the cage-changing workbench, and other search-related work. Based on this, the present invention can omit steps (3), (5), (10), and (11) in the conventional cage replacement operation, merge steps (2) and (4) in the conventional cage replacement operation into the current step (2), merge steps (7) and (8) in the conventional cage replacement operation into the current step (4), and simplify step (9) in the conventional cage replacement operation into the current step (5). Due to the merging and simplification of steps, the input of auxiliary and supervisory work can be reduced, and thus the number of operators can also be reduced accordingly.
