Description

Technical Field

[0001] The present invention relates to the technical field of biological experimental equipment, and in particular to an experimental animal cage system based on an NFC switch and a control method thereof. Background Art

[0002] Laboratory animals are artificially raised, with controlled microorganisms, and with clear genetic backgrounds or sources, and are used for scientific research, teaching, production, testing, and scientific experiments. Non-human primates (NHP) are currently the mainstream experimental animals in animal experiments. The primate experimental animals used in experiments are generally rhesus monkeys, crab-eating macaques, common marmosets, and pig-tailed macaques. Because their genes are highly consistent with humans, they can replace humans in early clinical trials.

[0003] During the experiment of non-human primates, the operator needs to catch the experimental animals and fix them in the corresponding position many times before operating them. After the experimental operation, the experimental animals need to be released. In the process of capturing and releasing, the feeding cages need to be opened and closed frequently. At present, the cage locks of the experimental animal cage system are still traditional mechanical lock switches. For operators who are holding the animals to move, they have to use keys to open the doors while controlling the movements of the animals. There is a risk of animals escaping, which is not conducive to the safety of the experimental animals or the health of the operators themselves. In addition, it is easy to put the cages in the wrong place, thus affecting the accuracy of the experimental data. In addition, the keys of traditional mechanical locks are small and similar, which are easy to confuse and lose, affecting the progress and efficiency of the experiment.

[0004] Therefore, there is an urgent need in this field for a new experimental animal cage system to replace the traditional mechanical lock, which is convenient for operators to conduct experiments and can accurately identify cage information to avoid misplacing cages. At the same time, no keys are required and there is no need to worry about key loss. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides an experimental animal cage system based on NFC switch, including an induction bracelet and a plurality of cages with the same structure;

[0006] A cage lock with the same structure is fixedly installed at the cage door of each cage, and the cage lock establishes NFC near-field communication with the induction bracelet, and the induction bracelet controls the opening and closing of the cage lock through NFC near-field communication technology;

[0007] Each of the cages is provided with an animal chip corresponding to the cage, the animal chip is used to store the information of the experimental animal placed in the corresponding cage, and the induction bracelet is used to identify and store the information of the experimental animal in the animal chip.

[0008] Specifically, the induction bracelet includes a strap and a bottom frame, two ends of the strap are respectively fixed on the left and right sides of the bottom frame, and a first control circuit board, a first NFC induction coil and a battery are arranged in the bottom frame.

[0009] Specifically, the cage lock is provided with a second control circuit board, a second NFC induction coil, an electromagnet, a capacitor and a lock core.

[0010] Specifically, a spring is also provided in the cage lock, and the spring is used to reset the lock core.

[0011] Specifically, an alarm is provided in the induction bracelet.

[0012] Specifically, the shell material of the cage lock is stainless steel, and the shell is provided with a data interface reserved for writing or updating software programs.

[0013] The present invention also provides a control method for an experimental animal cage system based on an NFC switch, wherein the cage system is the aforementioned experimental animal cage system based on an NFC switch, wherein the cage system adopts a passive communication mode, wherein the induction bracelet serves as an active card, and the cage lock serves as a passive card communication, and wherein the method comprises the following steps:

[0014] Step 1: The operator wears a sensing bracelet and approaches the animal chip. The sensing bracelet obtains the information of the experimental animal and temporarily stores it;

[0015] Step 2: The operator grabs the experimental animal and approaches the cage lock. The cage lock identifies and judges the experimental animal information temporarily stored in the sensing bracelet. If the information corresponds, the correct information is transmitted to the sensing bracelet and the electromagnet is controlled to open the cage lock. The operator completes the return of the experimental animal and closes the cage door. If the information does not correspond, the error information is transmitted to the sensing bracelet, and the sensing bracelet alarm issues an error alarm.

[0016] Specifically, in step 2, after the sensing bracelet receives the correct information, the temporarily stored experimental animal information is deleted.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the experimental animal cage system provided by the present invention, the induction bracelet obtains the experimental animal information in the animal chip through NFC communication, temporarily stores the corresponding animal information in the induction bracelet, and then matches the information through NFC communication with the cage lock. When the information matches, the cage door is opened to complete the placement of the experimental animal. The operation is simple, efficient and fast. The cage door can be opened only by close contact, which is convenient for the operator and improves the experimental efficiency.

[0019] 2. In the experimental animal cage system provided by the present invention, when the cage lock and the information of the induction bracelet do not match, the induction bracelet will sound an alarm, which not only improves the convenience of opening and closing the cage door, but also ensures the correspondence between the experimental animals and their cages, thereby ensuring the accuracy of data collection.

[0026] Embodiment 1

[0027] like Figure 1-3As shown, this embodiment shows an experimental animal cage system based on NFC switch, including an induction bracelet and multiple cages with the same structure;

[0028] Each cage door is fixed with a cage lock of the same structure. The cage lock and the induction bracelet establish NFC near-field communication. The induction bracelet controls the opening and closing of the cage lock through NFC near-field communication technology.

[0029] Each cage is provided with an animal chip corresponding to the cage, the animal chip is used to store the information of the experimental animals placed in the corresponding cage, and the induction bracelet is used to identify and store the information of the experimental animals in the animal chip.

[0030] The induction bracelet includes a strap 1 and a bottom frame 2. The two ends of the strap 1 are respectively fixed on the left and right sides of the bottom frame 2. A first control circuit board 3, a first NFC induction coil 4 and a battery 5 are arranged in the bottom frame 2.

[0031] The outer shell of the cage lock is made of stainless steel, which is waterproof and anti-corrosive, improving the safety and durability of the cage lock. The outer shell is reserved with a data interface, which is used to write or update the software program. The operator writes the control program and the cage position information corresponding to the cage lock in advance, and burns the software through the reserved data interface. The cage lock shell is provided with a second control circuit board 6, a second NFC induction coil 7, an electromagnet 8, a capacitor 9 and a lock core 10. A spring is also provided in the cage lock, which is used to reset the lock core 10.

[0032] The animal chip has the cage position information of the animal built in. When the induction bracelet is close to the animal chip, the induction bracelet obtains the cage position information of the animal and temporarily stores it in the induction bracelet. When the induction bracelet is close to the cage lock, the information stored in the induction bracelet matches the information of the cage lock. If the information in the induction bracelet corresponds to the cage lock information, the built-in program in the cage lock will control the electromagnet 8 in the lock to open the cage door. If the information does not correspond, an alarm is set in the induction bracelet. The induction bracelet receives the error message sent back and controls the alarm to issue a voice prompt to indicate that the animal is placed wrong. When the correct animal is successfully put back, the animal information temporarily stored in the induction bracelet will be reset and cleared for the next operation. When the induction bracelet and the cage lock are transmitting data, the power supply for the cage lock is provided by the induction bracelet, which is convenient for replacing batteries and can also prevent the device from causing electric shock to the animal.

[0033] This embodiment also shows a control method for an experimental animal cage system based on an NFC switch. The cage system is the aforementioned experimental animal cage system based on an NFC switch. The cage system adopts a passive communication mode, the induction bracelet is used as an active card, and the cage lock is used as a passive card communication. The method includes the following steps:

[0034] Step 1: The operator wears a sensing bracelet and approaches the animal chip. The sensing bracelet obtains the information of the experimental animal and temporarily stores it;

[0035] Step 2, the operator grabs the experimental animal and approaches the cage lock. The cage lock identifies and judges the experimental animal information temporarily stored in the sensing bracelet. If the information corresponds, the correct information is transmitted to the sensing bracelet and the electromagnet 8 is controlled to open the cage lock. The operator completes the return of the experimental animal and closes the cage door; if the information does not correspond, the error information is transmitted to the sensing bracelet, and the sensing bracelet alarm issues an error alarm.

[0036] After the induction bracelet receives the correct information, the temporarily stored experimental animal information will be deleted.

[0037] In summary, the above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
