[0036] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0037] Example:

[0038] This embodiment provides a test method for a hamster test chamber based on the Hall effect, and the steps are as follows:

[0039] S1: Place the hamsters in the working chamber and install the rotating wheel according to the number of hamsters. During this process, turn the screws to install the rotating wheel and the plum key. During the monitoring process, the hamster climbs onto the rotating wheel and drives the rotating wheel to rotate by running, which drives the induction wheel connected to it to rotate accordingly, and cooperates with the sensor to record the rolling, so as to record the rotating wheel data through the Hall effect;

[0040] S2: During this process, the function of the device can be switched. By driving the rotating wheel to rotate, the running situation of the hamster at a fixed speed can be recorded. By rotating the driving device, the plum blossom sleeve and the plum blossom key of the card installation mechanism are engaged and installed, and the driving motor is started to drive the multiple sets of rotating wheels to roll through the belt, so as to record the data;

[0041] S3: During the experimental monitoring process, the temperature and humidity in the box are adjusted by activating the environmental switching device to record the survival and habits of hamsters in different environments.

[0042] As a preferred embodiment of the above, the present invention is a hamster experimental cabin based on the Hall effect, and the monitoring device also includes: when the device is started, the main control box is started first, and the main control box includes a power supply, a signal transmitter and a single-chip microcomputer. The power supply provides the necessary power for the entire system. It is responsible for converting AC power into DC power, or directly providing DC power. The power supply must be able to provide stable voltage and current to ensure the normal operation of the single-chip microcomputer and other components. The single-chip microcomputer is a computer integrated on a chip, including a processor, memory and input / output interface. It controls the operation process of the entire system by executing pre-written programs. This procedure can include reading sensor data, processing information, making decisions, and sending control commands. The signal transmitter is used to send and receive signals, which can be analog signals or digital signals. At the sending end, it can convert the control signal from the single-chip microcomputer into a form suitable for long-distance transmission. In this process, according to the number of experimental hamsters, the bolts are turned to make threaded connections with the corresponding wheels and plum keys, so that multiple wheels or a single wheel are evenly arranged or in the center of the working chamber. The wheel is open on one side to facilitate hamsters to climb. Under the supply of electricity, the hamster runs and drives the wheel to rotate, and the induction wheel fixed with the wheel rotates accordingly. The sensor records the rotation of the induction wheel. The way the sensor and the induction wheel work through the Hall effect mainly involves using Hall elements to detect changes in the magnetic field. The Hall effect refers to the phenomenon that when current flows through a conductor or semiconductor placed in a magnetic field, a potential difference is generated in the direction perpendicular to the current and the magnetic field. This phenomenon is caused by the deflection of charged particles in the magnetic field due to the Lorentz force. When the induction wheel rotates, it periodically changes the strength of the magnetic field near the sensor. This is because when a metal part is close to the Hall sensor, it will concentrate the magnetic flux lines, thereby enhancing the magnetic field in the area; when a non-metal part passes by, the magnetic field is weakened. Whenever the magnetic field changes, a Hall voltage will be generated inside the Hall effect sensor accordingly. This voltage change can be converted into a digital signal or an analog signal output, which can be captured and processed by the electronic control system to calculate the rotation speed, angle or other related information.

[0043] As a preferred embodiment of the above-mentioned embodiment, a hamster experimental cabin based on the Hall effect of the present invention, the driving device also includes: when it is necessary to record the running speed and time of the hamster at a fixed speed of the wheel, the mounting plate is connected to the box body by screws, and can be disassembled when use is completed or maintenance is carried out. During this process, the bent plate is rotated to make it parallel to the box body, and the angle and position of the bent plate are fixed by rotating the knob on the first mounting seat. After the fixation is completed, the clamping mechanism is assembled with the corresponding plum blossom key, and the driving motor is started to rotate. The belt is driven to rotate by the rotation of the driving motor. The driving wheel and the driven wheel are connected by a belt, thereby driving the driven wheel and the wheel on the plum blossom key to rotate synchronously through the rotation of the belt.

[0044] As a preferred embodiment of the above-mentioned embodiment, a hamster experimental cabin based on the Hall effect of the present invention, the clamping mechanism also includes: in the process of fixing the rotating wheel, the flat head pin is inserted into the flat head groove by rotating, thereby driving the flat head pin through the flat head sleeve, and when the flat head pin is not inserted, due to the inclination angle on the flat head pin, the flat head sleeve will bounce through the oblique angle during the rotation process, and the spring is used for reset, so that the flat head sleeve cannot drive the flat head pin to rotate, and after the flat head pin is inserted into the flat head sleeve, the spring reverse thrust is used to fix it, and then the plum blossom key and the plum blossom sleeve are assembled to drive the rotating wheel to rotate.

[0045] As a preferred embodiment of the above, a hamster experimental cabin based on the Hall effect of the present invention also includes: when the humidity and temperature need to be adjusted during the process of switching the environment in the working chamber, the control can be carried out by starting the heater or humidifier. During the control process, the electric push rod is started to drive the rack connected to it to rotate, thereby driving the gear to rotate, and driving the adjustment plate on the shaft to rotate in the same direction, so as to control and blow the warm air or humidified air blown out by the fan.

[0046] As a preferred embodiment of the above, a hamster experimental cabin based on the Hall effect of the present invention also includes: by pulling the handle to drive the cover to rotate, the hamster is released from the top, and the visual baffle is connected with the lateral connecting plate to observe the situation in the working chamber. During this process, the hamster is fed in the feeding bowl and the bottom leakage plate is used to collect and clean the water.

[0048] The “first”, “second” and “third” in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
