Description

Technical Field

[0001] This invention relates to the field of life science research technology, and in particular to a system and method for collecting status data of animal containers based on RFID technology. Background Technology

[0002] Due to cleanliness requirements, laboratory animal facilities typically employ barrier systems to separate them from the general environment, controlling the entry and exit of personnel and materials and strictly managing the cross-transmission of microorganisms. This hinders communication between the inside and outside of these barriers during daily operations, causing significant inconvenience for information collection, recording, and transmission within the barrier, and substantially reducing work efficiency. Even though many facilities have installed interactive terminals such as computers and tablets inside the barriers, this does not fundamentally solve the aforementioned problems.

[0003] Existing RFID-based methods for tracking and managing laboratory animals are difficult to apply to the production of mice and rats. For example, attaching RFID tags to animal information cards is problematic for a production facility with tens of thousands of cages, where the cards need weekly updates, often leading to tags falling off or becoming confused. Handheld RFID readers are also insufficient for facilities producing millions of animals annually to effectively track, locate, and differentiate individuals. Some methods, in an effort to reduce the frequency of RFID tag disinfection, install the tags outside the container body, but this also carries the risk of incorrect installation and confusion.

[0004] Chinese patent document CN106875282A discloses an animal husbandry and management method based on RFID technology, including the following steps: associating the RFID code of an RFID tag with the basic animal information in a database, and then wearing the RFID tag on the animal's body or attaching it to an animal information card; collecting and recording various data related to animal husbandry through RFID reading and writing technology; uploading the collected data related to animal husbandry process to the database of the animal husbandry and management platform; and allowing managers to query and analyze the status of animals currently being raised or previously raised according to different query needs.

[0005] The technical solutions disclosed in the aforementioned patent documents and other existing related technologies have the following shortcomings when producing experimental mice and rats:

[0006] (1) It is difficult to put RFID tags on laboratory mice or rats. First, the animals are very small, making it difficult to put tags on them, as the size of traditional ear tags is much smaller than that of RFID tags. Second, rodents will bite and chew on the tags, which can easily damage them. Third, laboratory mice and rats are group animals, and they often play and fight, which can cause the tags to fall off, rendering them ineffective for identification and tracking.

[0007] (2) If the labels are pasted on the animal information tags, the cages and information tags need to be changed and updated periodically during daily feeding operations. This process can easily lead to confusion, falling off, or incorrect hanging of the information tags, making it difficult to ensure 100% consistency between the information tags and the animals in the cages. Furthermore, the animal information tags in cage A and cage B may have almost no difference in information content (such as breed, date of birth, etc.), but the animals contained in the boxes are definitely different. It is easy to cause confusion when changing and hanging the information tags.

[0008] (3) Using handheld terminals to scan tags cannot fundamentally solve the production management problems of laboratory animal barrier facilities, nor can it significantly improve work efficiency or significantly reduce the probability of errors and corresponding costs. For a medium-sized laboratory animal facility, there are tens of thousands of cages and boxes, and an annual output of millions of animals. If staff use handheld devices to scan, identify, enter information, and link it in the system, it would be a huge undertaking.

[0009] (4) When staff need to find which cage to house an animal of a certain breed that meets the requirements, they can only scan one by one using a handheld terminal device, which is very inefficient. It can take several hours to pinpoint which cage to house a specific animal.

[0010] (5) The method of scanning, recording, linking and searching in the database through handheld devices cannot update the production capacity of laboratory animal production facilities in real time. For example, at a certain moment, how many cages are occupied, how many cages are vacant, how many animals are in the process of changing cages, in the process of giving birth, in the process of nursing, or waiting to be sent to the customer's laboratory cannot be updated in real time and dynamically, and still cannot get rid of the problems caused by manual operation.

[0011] Therefore, in order to optimize the daily workflow of laboratory animal facilities, reduce cost-consuming and inefficient processes, and shorten the operation time of daily workflows, there is an urgent need for an animal container system that can be automatically identified, tracked, collect work status information, and provide feedback on the internal operation process of the facility. Summary of the Invention

[0012] To address one or more technical problems in the prior art, the present invention provides an animal container status data acquisition system based on RFID technology, comprising:

[0013] Switching unit, transponder unit, reader / writer unit, container, support;

[0014] The switching unit includes a triggering component and a sensing component. The triggering component and the transponder unit are disposed on the container, and the sensing component is disposed on the reader / writer unit. The reader / writer unit is disposed on the bracket, so that the RFID-based animal container status data acquisition system can be in either the first acquisition state or the second acquisition state:

[0015] First acquisition state: When the container is placed in the designated position of the bracket, the triggering component triggers the sensing component to make the reader unit enter the working state and emit radio frequency signals. After receiving the radio frequency signals, the transponder unit emits identification code information. After receiving the identification code information, the reader unit sends the container positioning information to the information management system. After sending the container positioning information, the reader unit enters the sleep state.

[0016] Second acquisition state: When the container is removed from the designated position of the bracket, the triggering component triggers the sensing component to enable the reader unit to enter the working state and emit radio frequency signals. After receiving the radio frequency signals, the transponder unit emits identification code information. The reader unit continues to receive the identification code information until it can no longer receive the identification code signal within a set time, and then sends the container departure information to the information management system. After sending the container departure information, the reader unit enters the sleep state.

[0017] Preferably, the triggering component is a magnet, the sensing component is a magnetic switch, the reader unit includes a housing, and a circuit board is provided inside the housing. The circuit board integrates an MCU main control module, an RF module, a baseband module, a network communication module, and an antenna module. The sensing component is electrically connected to the MCU main control module.

[0018] Preferably, the network communication module has a PoE power supply configuration to supply power to the reader unit via the PoE power supply configuration.

[0019] Preferably, the outer casing is provided with screw holes, and the support rod of the bracket is provided with a position-adjustable fixing module, and the fixing module is connected to the screw holes by screws.

[0020] Preferably, the transponder unit's chip, circuit, and antenna are encapsulated within a tag, which is encapsulated in a fixing bracket. The fixing bracket includes a front part and a rear part connected by snap-fit. The upper edge of the container has a pre-drilled hole, and the inner diameter of the pre-drilled hole has a protrusion. The front part and the rear part of the fixing bracket are respectively engaged on the front and rear sides of the protrusion. The outer surface of the front part of the fixing bracket is flush with the outer surface of the upper edge of the container.

[0021] Preferably, the triggering component is also encapsulated in the fixing bracket.

[0022] Preferably, the support is provided with a guide rail and a limiting mechanism. The guide rail is used to allow the upper edge of the container to slide in and out of the support, and the limiting mechanism is used to limit the container when it slides to a designated position on the support.

[0023] Preferably, the sensing component and the antenna module are jointly disposed in the antenna area of ​​the reader unit, so that when the container slides to a designated position on the bracket, the tag, the triggering component, the sensing component and the antenna module are located on the same axis.

[0024] Preferably, the fixing bracket is provided on the upper left and upper right edges of each of the containers;

[0025] Each reader unit contains two sets of sensing components and antenna modules. One set of sensing components and antenna modules is located in the antenna area on the right side of the reader unit, and the other set of sensing components and antenna modules is located in the antenna area on the left side of the reader unit.

[0026] The present invention also provides a data acquisition method based on the RFID-based animal container status data acquisition system, comprising:

[0027] When the container is placed in the designated position of the bracket, the triggering component triggers the sensing component to send a first control signal. After receiving the first control signal, the MCU main control module controls the reader unit to enter a first working state. The MCU main control module controls the radio frequency module to send a radio frequency signal through the antenna module. After receiving the radio frequency signal, the transponder unit sends identification encoding information. The baseband module decodes the identification encoding information received by the radio frequency module to obtain decoded data information. After receiving the decoded data information, the MCU main control module generates container positioning information. After sending the container positioning information to the information management system through the network communication module, the MCU main control module controls the reader unit to enter a sleep state.

[0028] When the container is removed from the designated position on the support, the triggering component triggers the sensing component to send a second control signal. After receiving the second control signal, the MCU main control module controls the reader unit to enter a second working state. The MCU main control module controls the radio frequency module to send a radio frequency signal through the antenna module. After receiving the radio frequency signal, the transponder unit sends out identification encoding information. The baseband module decodes the identification encoding information received by the radio frequency module to obtain decoded data information. The MCU main control module continues to receive the decoded data information until it can no longer receive the decoded data information within a set time, and then generates container displacement information. After the MCU main control module sends the container displacement information to the information management system through the network communication module, the MCU main control module controls the reader unit to enter a sleep state.

[0029] The beneficial effects of this invention are:

[0030] (1) Automated data acquisition and real-time transmission

[0031] This invention achieves automatic data acquisition and transmission of animal container status data through the coordinated operation of a switching unit, a transponder unit, and a reader / writer unit, eliminating the need for manual intervention. After acquiring data, the reader / writer unit transmits the information to the management system in real time via a network communication module, ensuring immediate data updates and dynamic management. This automated and real-time data processing method allows managers to monitor the feeding and experimental conditions of laboratory animals at any time, eliminating the need for manual inspection and recording, significantly improving management efficiency and the scientific basis of decision-making. Simultaneously, it reduces the error rate caused by manual operation, enhancing the accuracy and reliability of the data.

[0032] (2) Precise positioning and identification

[0033] This invention employs a trigger-type switching unit to ensure that the reader unit is activated only after the container is physically in place, avoiding accidental triggering and uncertainties in data acquisition. The precise positioning of the transponder unit and reader unit (e.g., coaxial cable design) further improves the stability of signal transmission and the accuracy of data acquisition, avoiding data errors caused by tag detachment or confusion in traditional methods. This high-precision data acquisition method significantly improves management efficiency and reduces repetitive work and resource waste caused by inaccurate data.

[0034] (3) Flexible installation and layout

[0035] The installation positions of the reader / writer unit and transponder unit of this invention can be flexibly adjusted according to actual needs, adapting to experimental animal facilities of different sizes and layouts. The support system is equipped with guide rails and limiting mechanisms to ensure that the containers are accurately positioned each time, further improving the stability of the system and the accuracy of data acquisition, reducing the additional costs and time consumption caused by facility adjustments, and ensuring the efficiency and reliability of the management process.

[0036] (4) Low power consumption and energy-saving design

[0037] The reader unit of this invention enters a sleep state after completing data acquisition, reducing the overall power consumption of the system. Simultaneously, the system uses PoE power supply, reducing the disruption to the clean environment caused by traditional power supply methods and improving the stability and reliability of the power supply. This design makes the system more economical and environmentally friendly during long-term operation, while also reducing interference with the laboratory animal facility environment.

[0064] like Figures 1-20 As shown, an animal container status data acquisition system based on RFID technology includes:

[0065] Switch unit 1, transponder unit 2, reader / writer unit 3, container 4, bracket 5;

[0066] The switching unit 1 includes a triggering component 101 and a sensing component 102. The triggering component 101 and the transponder unit 2 are disposed on the container 4, and the sensing component 102 is disposed on the reader / writer unit 3. The reader / writer unit 3 is disposed on the bracket 5, so that the animal container status data acquisition system based on RFID technology can be in either the first acquisition state or the second acquisition state:

[0067] First acquisition state: When the container 4 is placed in the designated position of the bracket 5, the triggering component 101 triggers the sensing component 102 to make the reader unit 3 enter the working state and emit radio frequency signals. After receiving the radio frequency signals, the transponder unit 2 emits identification code information. After receiving the identification code information, the reader unit 3 sends the container positioning information to the information management system. After sending the container positioning information, the reader unit 3 enters the sleep state.

[0068] Second acquisition state: When the container 4 is removed from the designated position of the bracket 5, the triggering component 101 triggers the sensing component 102 to make the reader unit 3 enter the working state and emit radio frequency signals. After receiving the radio frequency signals, the transponder unit 2 emits identification code information. The reader unit 3 continues to receive identification code information until it can no longer receive identification code signals within a set time, and then sends the container removal information to the information management system. After sending the container removal information, the reader unit 3 enters the sleep state.

[0069] The main function of the switch unit 1 is to activate the reader unit 3 and put it into working state when the container 4 (animal container) is in place on its corresponding support 5 (support system). The switch component 1 (trigger component 101) located on the container 4 triggers the switch component 1 (sensor component 102) located on the reader unit 3.

[0070] The transponder unit 2 is mainly used for: when the container 4 is in place in its corresponding bracket 5, the activated transponder unit 2 is coupled with the reader unit 3 located in the bracket 5. After receiving the energy signal (radio frequency signal) sent by the reader unit 3, the transponder unit 2 is activated and sends a unique identification code information (identity code) to the reader unit 3 through the carrier wave.

[0071] The reader unit 3 is mainly used to: transmit wireless radio frequency signals to provide energy signals to the transponder unit 2 within its radiation range, and capture the carrier signals returned by the transponder unit 2 to demodulate the corresponding identification code information; the coupling method between the reader unit 3 and the antenna of the transponder unit 2 can be different according to the actual use of animal barrier facilities and animal container systems, such as inductive coupling, electromagnetic coupling, etc.; the frequency band of the wireless radio frequency can be low frequency, high frequency, ultra-high frequency, microwave, etc., depending on the different use scenarios.

[0072] When inductive coupling is used, a high-frequency (HF) RFID communication module can be selected. Data transmission between transponder unit 2 and reader unit 3 adopts a load modulation method. Its advantages include a shorter radiation distance and better control over the reader signal radiation range. When the transponder enters the alternating magnetic field generated by the reader, an induced voltage is generated on the transponder's antenna coil. At sufficiently close distances, the energy captured by the transponder antenna circuit can supply the operating requirements of the transponder chip. When the transponder chip is working, it converts its internally stored unique code into binary form and alters its antenna reactance by alternating circuit switching, thereby affecting the reactance of the reader antenna. After receiving the reactance change information, the reader circuit chip decodes it accordingly to recover the binary code information, thus achieving data transmission.

[0073] When electromagnetic coupling is used, an ultra-high frequency (UHF) RFID communication module can be selected, which is characterized by relatively long communication distance, high efficiency, and fast reading speed. After the reader emits radio frequency electromagnetic waves into space, the transponder absorbs the energy brought by the voltage generated by the alternating magnetic field. Part of the remaining energy is reflected back to the reader by the transponder antenna. The reflected electromagnetic waves are modulated by the transponder's load and carry the corresponding modulation signal. This modulated signal contains the encoded information stored in the transponder chip, thereby realizing the transmission of data information.

[0074] The software embedded in transponder unit 2 and reader unit 3 can be used to drive the various functional modules in transponder unit 2 and reader unit 3, ensuring that the status information of animal containers (position information, departure information) can be collected safely, stably and efficiently. At the same time, the collected data information is processed and sent to the backend application software and management information system.

[0075] After the sensing component 102 is triggered by the switch module trigger component 101 of the animal container, the reader unit 3 is activated and enters the working state. At this time, without any intervention from the staff, the reader unit 3 can couple with the transponder unit 2 of the animal container 306 through its antenna module, supply power to the transponder unit 2, receive the radio frequency signal returned by the transponder unit 2, and automatically identify the identification code information of the transponder tag of the animal container; thereby realizing the identification and tracking of different animal containers, and realizing the automatic collection, recording and transmission of production process operation data.

[0076] Existing laboratory animal management technologies largely rely on manual operation or simple tag identification, making it difficult to achieve automated and systematic data collection and management. This embodiment constructs a complete animal container status data acquisition system based on RFID technology, encompassing a switch unit, a transponder unit, a reader / writer unit, and a software control unit. These units work collaboratively to achieve automatic collection, transmission, and processing of animal container status data, providing a completely new technical architecture and solution for laboratory animal management, fundamentally different from existing technologies. In laboratory animal facilities, traditional methods often face problems of untimely and inaccurate data recording, leading to low management efficiency. This system, by automating data collection, significantly reduces manual intervention and human error. Simultaneously, real-time acquisition of container status data allows managers to promptly grasp the feeding and experimental status of laboratory animals, improving management efficiency.

[0077] In a specific embodiment of the present invention, the triggering component 101 is a magnet, the sensing component 102 is a magnetic switch, the reader unit 3 includes a housing 307, and a circuit board 305 is provided inside the housing 307. The circuit board 305 integrates an MCU main control module, a radio frequency module, a baseband module, a network communication module 304, and an antenna module 306. The sensing component 102 is electrically connected to the MCU main control module.

[0078] The sensing component 102 can be connected to the circuit board 305 via a signal cable to achieve electrical connection between the sensing component 102 and the MCU main control module.

[0079] The baseband module is responsible for demodulating the signals received by the RF module, converting the RF signals into digital information. After demodulating the signals received by the RF module, the baseband module obtains the corresponding digital information and transmits this information to the MCU main control unit for analysis and processing. Finally, the processed results are sent to the application program or information management system through the network communication module 304.

[0080] When reader unit 3 is operating, transponder unit 2 receives the radio frequency signal and sends out identification code information. The radio frequency module receives this signal, and then the baseband module demodulates it to obtain the corresponding digital information, preparing for subsequent processing. The MCU main control module decodes, analyzes, and processes the data information demodulated by the baseband module. After the baseband module demodulates the signal into digital information, the MCU main control module further processes this information, extracting valid data such as the container identification code from the digital information, thereby realizing the acquisition and analysis of animal container status data.

[0081] The MCU main control module can also be used to: receive the trigger signal of the switch unit 1 and activate the reader unit 3 to enter the working state; trigger the radio frequency module to send radio frequency signals to the transponder unit 2 through the antenna module 306 of the reader unit; and control the network communication module 304 to send the processed data information to other applications or management information systems.

[0082] The reader unit 3 can be installed on the support system or other work points where data on the status of animal containers needs to be collected via a fixing device. The reader unit 3 can be arranged corresponding to one or more animal containers.

[0083] When the container 4 is correctly positioned on its support 5, the triggering component 101 reaches a position that can trigger the sensing component 102. The triggering component 101 can trigger the sensing component 102 in a contact or non-contact manner.

[0084] Contact-based triggering, such as mechanical switch triggering, occurs when the container 4 is correctly positioned on the support 5. The triggering component 101 directly contacts the sensing component 102, and mechanical pressure alters the internal structure of the sensing component 102, thus triggering its operation. For example, similar to a push-button switch, the triggering component 101 acts like an object pressing a button. When it reaches the position of the sensing component 102, it presses the button, activating the circuit and triggering the sensing component 102. Preferably, the sensing component 102 can be a microswitch. When the container 4 is in place, the triggering component 101 presses the contacts of the microswitch, closing its normally open contacts and generating a trigger signal.

[0085] Non-contact triggering can be achieved using a magnetic switch. The triggering component 101 is a magnet, and the sensing component 102 is a magnetic switch. When the container 4 is in place, the magnet (triggering component 101) approaches the magnetic switch (sensing component 102). The magnetic switch senses the change in magnetic field, thereby generating a trigger signal that puts the reader unit 3 into operation. Alternatively, non-contact triggering can be achieved using infrared sensing, capacitive sensing, or other methods. For example, an infrared transmitter can be installed on the container 4 as the triggering component 101, and an infrared receiver can be installed on the reader unit 3 as the sensing component 102. When the container 4 is in place, the infrared light emitted by the transmitter is detected by the receiver, thus triggering the reader unit 3.

[0086] The activation of reader unit 3 by switch unit 1 can be either physical or logical.

[0087] Physical activation, taking a magnetic switch as an example, involves the interaction between the triggering component 101 (magnet) and the sensing component 102 (magnetic switch). Through the action of the magnetic field, the internal circuit state of the reader unit 3 is directly changed, thereby activating the reader unit 3. This is one form of physical activation. Alternatively, a mechanical connection can be used. When the triggering component 101 is in position, it directly pushes the internal mechanical structure of the reader unit 3, thereby connecting the circuit and enabling the reader unit 3 to begin operation. This is another form of physical activation.

[0088] Activation can be achieved through logic. For example, when triggering component 101 triggers sensing component 102, sensing component 102 sends an electrical signal to the MCU main control module of reader unit 3. The MCU main control module, based on a preset logic program, determines that the signal meets the activation conditions and then controls the various functional modules of reader unit 3 to begin operation. This is one form of logical activation. Specifically, for example, the signal sent by sensing component 102 can be used as an interrupt request signal and input to the MCU main control module. Upon receiving this interrupt signal, the MCU main control module, according to its internally pre-written program, sends enable signals to the RF module, baseband module, etc., activating these modules and thus activating reader unit 3.

[0089] In one specific embodiment of the present invention, the network communication module 304 has a PoE power supply configuration to supply power to the reader unit 3 via the PoE power supply configuration.

[0090] The PoE power supply configuration of the network transmission module 304 can be used to supply power to the reader unit 3 via a network switch.

[0091] Laboratory animal facilities have unique environments with strict cleanliness requirements, necessitating controlled access for personnel and materials and strict management of cross-contamination of microorganisms. In such environments, traditional power supply cabling can easily disrupt the cleanliness of the facility, increasing the risk of microbial contamination. PoE power supply, however, only requires laying Ethernet cables, reducing the need for additional power lines and minimizing the impact on the cleanliness of the facility. Furthermore, traditional power supply methods are susceptible to interference from the complex electromagnetic environment within the facility, affecting power stability. PoE technology better adapts to this complex electromagnetic environment, ensuring stable power supply to the reader unit and uninterrupted data acquisition. This choice of power supply method fully considers the special environmental needs of laboratory animal facilities. In the management of laboratory animals, the continuity of data acquisition is crucial. Traditional power supply methods may lead to unexpected power outages for the reader unit due to battery issues or power adapter malfunctions, resulting in data loss or interruption of data acquisition. PoE power supply, via Ethernet cables, provides a continuous and stable power supply to the reader unit as long as the network connection remains intact, significantly reducing data acquisition interruptions caused by power supply problems. During long-term observation of laboratory animals, traditional power supply methods may result in the loss of data for hours or even days due to battery depletion. However, a system powered by PoE can ensure uninterrupted data acquisition, providing researchers with complete and accurate data and improving the reliability of experimental results.

[0092] In one specific embodiment of the present invention, the outer shell 307 is provided with a screw hole 302, and the support rod of the bracket 5 is provided with a position-adjustable fixing module 308, and the fixing module 308 is connected to the screw hole 302 by screws.

[0093] The reader unit 3 has four screw holes 302 at both ends for fixed installation. It is installed on the bracket 5 by cooperating with the mounting and fixing module 308. The installation position of the reader unit 3 is related to the positioning position of the container 4 (the designated position of the bracket 5) and the position of the transponder unit 2 installed on the outer wall of the container 4, so as to ensure that the container status data acquisition system can work normally and accurately.

[0094] The layout and equipment placement within laboratory animal facilities change due to variations in experimental projects, animal species, and numbers. In such an environment, traditional fixed installation methods cannot adapt to these dynamic changes. Changing equipment positions often requires reinstallation or even replacement, resulting in high costs and complex operations. This embodiment fully considers this practical need. Through the adjustable fixing module 308 and screw holes 302, the height, angle, and other positional parameters of the reader unit 3 can be easily adjusted. When the placement of the laboratory animal cages changes, or when other equipment is added that affects the reader's signal reception, the position of the reader unit 3 can be easily adjusted to ensure optimal signal interaction with the transponder unit 2 on the container.

[0095] In one specific embodiment of the present invention, the chip, circuit and antenna of the transponder unit 2 are encapsulated in a tag 201. The tag 201 is encapsulated in a fixed bracket. The fixed bracket includes a front part 203 and a rear part 202 of the fixed bracket connected by a snap fastener. The upper edge of the container 4 is provided with a reserved hole 401. The inner diameter of the reserved hole 401 is provided with a protrusion 4011. The front part 203 and the rear part 202 of the fixed bracket are respectively snapped on the front and rear sides of the protrusion 4011. The outer surface of the front part 203 of the fixed bracket is flush with the outer surface of the upper edge of the container 4.

[0096] The transponder unit 2 can employ a passive operating mechanism. Its operating energy comes from the alternating magnetic field generated by the radio frequency signal emitted by the reader unit 3, which cuts through the antenna circuit of the transponder unit 2, generating a momentary current that powers the chip and circuitry of the transponder unit 2. The chip of the transponder unit 2 can be a passive radio frequency identification (RFID) chip. The transponder unit 2 chip, its circuitry, and antenna module can be encapsulated together within a nylon tag 201, and mounted on the pre-drilled opening 401 at the upper edge of the bottom of the cage (container) via a mounting bracket. When the container 4 is correctly positioned on the bracket 5 via the track 6, the antenna area 301 of the reader unit 3 and the transponder unit 2 are aligned on the same axis. Figures 11-13 As shown.

[0097] The transponder unit 2's chip, circuit, antenna and other modules are encapsulated in the tag 201, which can withstand various sterilization operations such as high-temperature sterilization, chemical reagent soaking, and wiping of experimental animal barrier facilities. The material used to encapsulate the tag 201 can be a material that does not have a shielding effect on electromagnetic waves, such as engineering plastics, nylon, paper (polyester fiber paper, polypropylene fiber paper, polytetrafluoroethylene paper, engineering plastic paper) and other non-metallic materials.

[0098] Preferably, the transponder unit 2's chip, circuit, and antenna are encapsulated within a nylon label 201, which can withstand various sterilization processes such as high-temperature sterilization, chemical reagent immersion, and wiping used in laboratory animal barrier facilities. The nylon encapsulation label also does not shield electromagnetic waves. The mounting bracket can also be made of nylon.

[0099] The radio frequency chip of the transponder unit 2 contains a fixed-format, unique identification code. When the tag 201 is installed on the bottom upper edge of the container 4 via the fixed bracket, it defines a unique identification code for the animal container, which can identify, track and locate the container and the animal contained in the container 4.

[0100] In addition to being installed on the upper edge of container 4, label 201 can also be installed at any other location on the container via a mounting bracket, such as the side wall, bottom, or top of the container. The mounting bracket can be made of any material that meets the daily maintenance requirements of laboratory animals, such as engineering plastics or stainless steel. The pre-drilled hole 401 can be designed as an elongated circular hole. Using the above-described embodiment, after installing the mounting bracket, it can be ensured that the outer surface of container 4, where the transponder unit 2 is installed, remains smooth and flush.

[0101] Laboratory animal facilities require frequent cleaning and disinfection of containers, while ensuring that labels function stably in complex environments without affecting the normal use of the containers. Traditional adhesive labels are prone to falling off or being damaged during cleaning and disinfection, affecting data collection and animal management. This embodiment's design allows the transponder unit to be securely installed on the container, preventing damage during cleaning and disinfection. The snap-fit ​​fixing bracket tightly secures the label, preventing it from shaking or falling off during container use. The installation method, which mates with pre-drilled holes and protrusions, ensures installation stability and ensures that the front outer surface of the fixing bracket is flush with the upper edge of the container, without obstructing the placement and handling of the container. This effectively solves the problems of traditional installation methods in laboratory animal facility environments.

[0102] In one specific embodiment of the present invention, a triggering component 101 is also encapsulated in the fixed bracket.

[0103] The triggering component 101 and the transponder unit are integrated into a fixed bracket, which facilitates more efficient collaboration between the two. During system operation, when the container 4 is placed at the designated position on the bracket 5, the triggering component 101 triggers the sensing component 102, activating the reader unit 3. Simultaneously, the transponder unit 2 must also promptly exchange signals with the reader unit 3. Encapsulating the triggering component 101 within the fixed bracket allows for precise control of its relative position to the transponder unit 2, ensuring that while the triggering component 101 triggers the reader unit 3, the transponder unit 2 can quickly respond to the radio frequency signal emitted by the reader unit 3, thus improving the collaborative efficiency of system triggering and data acquisition.

[0104] In one specific embodiment of the present invention, the bracket 5 is provided with a guide rail 6 and a limiting mechanism. The guide rail 6 is used for the upper edge of the container 4 to slide in and out of the bracket 5, and the limiting mechanism is used to limit the container 4 when it slides to a designated position on the bracket 5.

[0105] like Figures 11-13 As shown, after the container 4 is correctly positioned on the bracket 5 after being inserted into the guide rail 6, the transponder unit 2 and the antenna area 301 of the reader unit 3 are coaxially aligned. At this time, the switch triggering component 101 embedded in the fixed bracket interacts with the sensing component 102 located in the antenna area 301 of the reader unit 3, triggering the magnetic switch to open and activating the relevant modules integrated into the circuit board 305 of the reader unit 3 to enter the working state. After the reader unit 3 is activated by the switch module 1, its radio frequency module emits a wireless radio frequency signal to the corresponding animal container side through the antenna module 306. After the antenna circuit of the transponder unit 2 of the container 4 receives the energy of the wireless radio frequency signal, it generates a current, activates the chip of the transponder unit 2, and transmits the identification code information to the reader unit 3 through the carrier wave. Through this process, the reader unit 3 realizes the identification, tracking and collection of the status data information of the animal container.

[0106] The limiting mechanism can be a protrusion, groove, baffle, buckle, spring, damping element, etc. The limiting mechanism can be located in the middle or at the end of the guide rail 6. When the limiting mechanism is located at the end of the guide rail 6, the container 4 can be taken out and placed from one side of the bracket 5; when the limiting mechanism is located in the middle of the guide rail 6, the container 4 can be taken out and placed from both the front and rear sides of the bracket 5, for example:

[0107] The container 4 has an arc-shaped protrusion, and the guide rail 6 has an arc-shaped groove in the middle. When the operator inserts the container 4 into the support 5 from the front, the arc-shaped protrusion engages with the arc-shaped groove, and the container 4 pauses its forward movement. When the operator continues to push the container 4 from the front of the support 5, or pulls the container 4 from the rear of the support 5, the arc-shaped protrusion disengages from the arc-shaped groove, and the container 4 can be removed from the rear of the support 5. The technical advantages of this design include improved space utilization flexibility, easier equipment maintenance, and enhanced data acquisition stability.

[0108] In the process of acquiring data on the status of laboratory animal containers, accurate positioning of the containers is crucial for the accuracy of data acquisition. If the container's position deviates significantly, the reader unit may be unable to accurately read the information from the transponder unit, leading to data acquisition errors or omissions. The guide rail and limiting mechanism design in this embodiment effectively solves this problem. Through the guidance of the guide rail and the positioning of the limiting mechanism, the container is placed on the support in the same position and posture each time, ensuring the relative position stability between the transponder unit and the reader unit on the container, thus improving the accuracy and stability of data acquisition. The guide rail and limiting mechanism not only position the container but also enhance the stability and durability of the system to a certain extent.

[0109] In one specific embodiment of the present invention, the sensing component 102 and the antenna module 306 are jointly disposed in the antenna region 301 of the reader unit 3, so that when the container 4 slides to the designated position of the support 5, the tag 201, the triggering component 101, the sensing component 102 and the antenna module 306 are located on the same axis.

[0110] In experimental animal facilities, various interference factors exist, such as electromagnetic interference from other electronic devices, which can easily lead to unstable signal transmission and false triggering of the system. This embodiment reduces signal interference during transmission through precise component layout. When all components are located on the same axis, the directionality of signal transmission is stronger, reducing signal scattering and reflection, and minimizing the impact of other interference sources on the signal. Simultaneously, this layout makes the process of triggering component 101 triggering sensing component 102 more stable and reliable, reducing the possibility of false triggering and effectively solving the problems of signal interference and false triggering in complex environments of traditional systems. The coaxial layout of components also helps improve the system's response speed. When the container 4 is placed at the designated position on the support 5, triggering component 101 can quickly trigger sensing component 102, and antenna module 306 can quickly interact with tag 201. In actual operation, this rapid response can improve work efficiency and reduce operator waiting time.

[0111] In one specific embodiment of the present invention, a fixing bracket is provided on the upper left edge and the upper right edge of each container 4;

[0112] Each reader unit 3 has two sets of sensing components 102 and antenna modules 306 inside. One set of sensing components 102 and antenna modules 306 is located in the antenna area 301 on the right side of the reader unit 3, and the other set of sensing components 102 and antenna modules 306 is located in the antenna area 301 on the left side of the reader unit 3.

[0113] The data acquisition system of this invention can be installed in various ways:

[0114] like Figure 17 As shown, for a container support system consisting of m rows and n columns, n+1 columns of reader units 3 can be deployed. Each animal container is equipped with two sets of transponder units 2, located on the two long sides of the container 4. Each reader unit 3 is equipped with two sets of magnetic switches (sensing components 102) and two sets of antenna modules 306, located on both sides of the reader unit 3. This ensures that the status data acquisition of each container 4 has two acquisition points, maximizing the accuracy of the container status data acquisition. Specifically, for example, the container 4 in column D has two sets of magnetic switches, L and R, on its left and right sides. These can be defined in the program: when the R magnetic switch on the left side and the L magnetic switch on the right side of the container 4 are both in the open state, the container 4 in column D is accurately in the specified position.

[0115] like Figure 18 As shown, for a container support system consisting of m rows and n columns, n columns of reader units 3 can also be deployed, with each reader unit only identifying the container 4 on one side.

[0116] like Figure 19 As shown, for a container support system consisting of m rows and n columns, n-1 columns of reader units 3 can also be arranged. Each reader unit 3 uses the magnetic switches and antenna modules 306 on both sides to work in correspondence with the transponder unit 2 of a container 4. The two sets of antenna modules 4 and magnetic switches share the other modules of each reader unit 3.

[0117] For the control logic of the data acquisition system of this invention, various different control logics can be set according to different usage scenarios. The following is one type of control logic:

[0118] Switch unit 1 is a magnetic switch and serves as the logic control switch for reader unit 3.

[0119] Once container 4 is inserted into guide rail 6 and correctly positioned in the designated location on bracket 5, triggering component 101 triggers sensing component 102. At this time, the magnetic switch (sensing component 102) opens and sends an activation signal. Upon receiving the activation signal, the MCU main control module of reader unit 3 supplies power to the radio frequency module and issues a command. The radio frequency module sends a radio frequency signal to transponder unit 2. If the chip in transponder unit 2 is activated and returns the corresponding identification code information via carrier wave, the MCU main control module processes the demodulated data and transmits it to the management information system via network communication module 304. If the radio frequency module of reader unit 3 does not receive feedback from transponder unit 2 after sending a radio frequency signal, the MCU main control module issues another command to the radio frequency module to send a radio frequency signal until the identification information fed back by the chip in transponder unit 2 is captured. After acquiring the positioning status information of container 4, reader unit 3 enters sleep mode.

[0120] When the container is removed from the track and leaves the support system, the magnetic switch closes, and the reader unit is reactivated by logic. The MCU control unit sends a command to the RF module, which then sends an RFID signal to the transponder unit 2. If no further RF feedback signal is received from the transponder unit 2, the reader unit 3 has acquired the status information that the container 4 has left. After transmitting this status data to the management information system via the network communication module 304, the reader unit 3 enters sleep mode again.

[0121] Preferably, the reader unit 3 is also provided with a working indicator light 303, which can be used to indicate to the operator whether the cage is in place or which cage is the object being searched by using different colors.

[0122] A data acquisition method for an animal container status data acquisition system based on RFID technology includes:

[0123] When container 4 is placed in the designated position of bracket 5, triggering component 101 triggers sensing component 102 to send a first control signal. After receiving the first control signal, MCU main control module controls reader unit 3 to enter the first working state. MCU main control module controls radio frequency module to send radio frequency signal through antenna module 306. After receiving the radio frequency signal, transponder unit 2 sends out identification code information. Baseband module decodes the identification code information received by radio frequency module to obtain decoded data information. After receiving the decoded data information, MCU main control module generates container positioning information. After sending the container positioning information to information management system through network communication module 304, MCU main control module controls reader unit 3 to enter sleep state.

[0124] When container 4 is removed from the designated position on bracket 5, triggering component 101 triggers sensing component 102 to send a second control signal. After receiving the second control signal, the MCU main control module controls reader unit 3 to enter the second working state. The MCU main control module controls the radio frequency module to send radio frequency signals through antenna module 306. After receiving the radio frequency signal, transponder unit 2 sends out identification code information. The baseband module decodes the identification code information received by the radio frequency module to obtain the decoded data information. The MCU main control module continues to receive the decoded data information until it can no longer receive the decoded data information within a set time, and then generates container removal information. The MCU main control module sends the container removal information to the information management system through network communication module 304, and then controls reader unit 3 to enter sleep state.

[0125] The sleep state of reader unit 3 refers to a low-power state entered after transmitting container positioning or departure information. When container 4 is placed in the designated position on bracket 5, reader unit 3 receives the identification code information from transponder unit 2 and sends the container positioning information to the information management system. It also enters sleep state after container 4 is removed from the designated position on bracket 5 and reader unit 3 sends the container departure information. The sleep state is controlled by the MCU main control module, which controls reader unit 3 to enter sleep mode after transmitting the corresponding information. In sleep mode, components that only operate during data acquisition, such as the RF module, stop working. However, components responsible for monitoring container status changes, such as the magnetic switch (sensor 102) used to detect whether the container has been triggered, remain active so that reader unit 3 can be woken up promptly when the container status changes.

[0126] The RF module in reader unit 3 is responsible for transmitting RF signals to communicate with transponder unit 2 during data acquisition, but it does not need to operate in sleep mode. After receiving the container's position or departure information and completing the transmission to the information management system, the MCU main control module will cut off the power supply to the RF module. For example, by using a switching element in the control circuit to prevent current from flowing to the RF module, it will stop transmitting and receiving RF signals, thereby reducing the module's power consumption. The baseband module is mainly responsible for demodulating the signals received by the RF module and is also in a non-operating state in sleep mode. The MCU main control module will control the baseband module to stop working, stopping the demodulation processing of signals, reducing unnecessary computation and power consumption.

[0127] After the network communication module 304 completes data transmission, the MCU main control module can adjust its operating mode to reduce its power consumption. For example, the network communication module can be set to a low-power monitoring mode, maintaining only basic network connection detection functions and waiting for the next data transmission request, thus avoiding continuous full-power operation.

[0128] When reader unit 3 enters sleep mode, the MCU main control module keeps the magnetic switch (sensor 102) responsible for monitoring changes in the container's status active. The magnetic switch is electrically connected to the MCU main control module and continuously monitors for any new changes in the container's status. Once the container's status changes, such as when the container is placed in or removed from the designated position on the bracket 5, the magnetic switch immediately senses the change in magnetic field and sends a signal to the MCU main control module, waking up reader unit 3 and enabling it to enter the corresponding working state to continue data acquisition and transmission.

[0129] When container 4 is placed into the designated position on the support 5, triggering component 101 triggers sensing component 102 to send a first control signal (e.g., a magnetic switch open signal); when container 4 is removed from the designated position on the support 5, triggering component 101 triggers sensing component 102 to send a second control signal (e.g., a magnetic switch close signal). The MCU main control module controls the reader unit 3 to enter the corresponding working state based on whether it receives the first or the second control signal, thereby distinguishing whether container 4 is in the removal or placement process.

[0130] The set time can be freely adjusted according to specific application scenarios, component performance, and user operating habits. For example, if the frequency of detection and recognition of the encoded signal by reader unit 3 is relatively high, and the container removal operation can be completed in a short time, the set time for detecting the disappearance of the signal can be relatively short, such as 0.5 to 1 second; if the detection frequency is low and the user's operating skills are not good, in order to ensure that the container has been accurately removed, the set time can be extended to 3 to 5 seconds as needed.

[0131] In practical use, the reader unit 3 can be installed at one or more specific locations on the animal container support; the transponder unit 2 can be installed on the outer wall of the animal container, and the installation position of the transponder unit 2 should be such that after the container 4 is in place on the support 5, the transponder unit 2 and the reader unit 3 are coupled; after the animal container is placed in the support system, the triggering component 101 of the switch unit 1 triggers the sensing component 102, activating the reader unit 3 to enter the working state; the reader unit 3 emits a wireless radio frequency signal and collects the identification code information returned by the transponder unit 2, thereby obtaining the status data of the container 4; the MCU main control module of the reader unit 3 processes and analyzes the obtained status data and sends it to the application program or information management system through the API interface.

[0132] More specifically, the RFID identification technology used in this invention is near-field identification. Whether based on a high frequency of 13.56MHz or an ultra-high frequency of 925MHz, the identification range is controlled within 1cm. This ensures accuracy from the technical level of RFID itself. By setting up a switch unit 1, this invention ensures that the reader will only be triggered and emit an radio frequency signal after the container 4 is physically in place. If the placement is incorrect, the reader will not be triggered, thereby further avoiding uncertainty.

[0133] Traditional data acquisition methods suffer from numerous problems regarding data accuracy, timeliness, and system energy consumption. Manual recording is prone to human error, simple scanning methods cannot monitor container status changes in real time, and prolonged device operation consumes significant energy. The data acquisition method in this embodiment, through component triggering and automatic collaborative operation of various modules, achieves real-time monitoring of container status and automatic data acquisition and transmission, greatly improving data accuracy and timeliness. Furthermore, the design of the reader unit entering a sleep state after completing the data acquisition task effectively reduces system energy consumption.

[0134] Compared with the prior art, the present invention can solve at least the following technical problems:

[0135] Solving the problem of difficulty in tagging animals: This invention eliminates the direct attachment of RFID tags to animals. Instead, the transponder unit 2's chip, circuitry, and antenna are encapsulated within the tag 201, which is then placed in a mounting bracket and installed on the container 4. This avoids problems such as small animals being unable to wear tags, rodents biting at the tags, and tags falling off due to playful fighting among group animals. It protects the tags while indirectly enabling animal identification, tracking, and location through container recognition.

[0136] Solving the problem of information tag management: This invention eliminates the need to affix tags to animal information tags. Instead, it uses a transponder unit and triggering component installed on the container, along with a reader / writer unit and sensing component on the support frame, to automatically collect and transmit container status data. The system automatically records relevant information when the container is in or out of position, eliminating the need for frequent manual replacement and management of the information tags. This avoids problems such as tag confusion, detachment, and incorrect hanging, ensuring accurate correspondence between information and the animal.

[0137] Improving work efficiency and reducing error rate: The system of this invention realizes automated data acquisition and transmission. The reader unit 3 is automatically triggered to work when the container status changes, collecting the identification code information of the transponder unit 2 and sending it to the information management system. Compared with handheld terminal scanning, no manual operation is required, which greatly improves work efficiency, while reducing errors caused by manual operation, thus lowering the error probability and cost.

[0138] Facilitates animal location: When it is necessary to locate a specific breed of animal, the system can collect and update the status information of the container in real time. The location of the cage where the animal is located can be quickly found through the information management system, without having to scan one by one as with a handheld terminal. This greatly improves the search efficiency and saves time and labor costs.

[0139] Real-time updates of production capacity: The system of this invention can collect real-time information on the placement and removal of containers, and send the data to the information management system through the network communication module 304, realizing real-time and dynamic updates on the production capacity of laboratory animal production facilities. Managers can monitor cage occupancy, availability, and various animal conditions at any time, enabling timely management decisions and reducing the lag and inaccuracies caused by manual operation.

[0140] Real-time monitoring of cage occupancy and availability: The system of this invention monitors the cage status through the coordinated operation of a switch unit, a transponder unit, and a reader / writer unit. When a cage (container 4) is placed in the designated position on the support 5, the triggering component 101 triggers the sensing component 102, the reader / writer unit 3 enters the working state, the transponder unit 2 sends identification code information, and the reader / writer unit 3, upon receiving it, sends container placement information to the information management system. When a cage is removed, the reader / writer unit 3 is also triggered. If no identification code signal is received within a set time, the reader / writer unit 3 sends container removal information. Based on the received placement and removal information, the information management system can count the number of occupied and available cages in real time. In an experimental animal facility with multiple cages and support systems, the reader / writer unit 3 continuously collects data and transmits it to the information management system. The system backend can analyze and statistically analyze this data to present the accurate number of currently occupied and available cages at any time.

[0141] Monitoring Animal Status: Information regarding animal status (e.g., cage changing, laboring, nursing, or awaiting shipment to a client's laboratory) can be dynamically updated by combining records from the information management system with initial manual input. Before an animal enters its cage, its initial status information is manually entered into the information management system and associated with the identification code of the corresponding cage's transponder unit 2. When the cage status changes, such as moving to a different shelf, the system records the time and the cage's movement trajectory. Combined with the animal's initial status information, it can infer whether the animal is in cage changing status. If specific areas are set up in the laboratory animal facility, such as laboring or nursing areas, when a cage containing an animal enters a shelf in these areas, the reader unit 3 collects data and sends it to the information management system. Based on the cage's location and the animal's initial status information, the system can update the animal's status to laboring or nursing. For animals awaiting shipment to a client's laboratory, when the cage is marked as ready for shipment, the system updates its status to awaiting shipment. Furthermore, when the cage leaves the facility, the departure information collected by the reader unit 3 further confirms that the animal has been shipped.

[0142] Reducing Human Intervention: Traditional methods rely on manual recording and statistics, which are prone to errors and inefficient. This invention, through automated data collection and transmission, significantly reduces human intervention. The reader unit 3 enters a sleep state after completing data collection, reducing system power consumption. It also automatically triggers operation when the container status changes, ensuring timely and accurate data collection. The information management system automatically analyzes and statistically processes the collected data, updating the status information of the animals and cages in real time. Managers can access the necessary data at any time through this system, eliminating the need for frequent manual statistics and recording, effectively avoiding the problems caused by manual operation.

[0143] In summary, this invention enables automated acquisition, precise positioning and identification of animal container status data, flexible installation and layout, low power consumption and energy-saving design, as well as durability and reliability.

[0144] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
