[0002] Water maze experiments are widely used in research fields such as cognition, memory, and neurological disorders, and are commonly used with rodents such as mice and rats. However, traditional water maze platforms are mainly designed for larger animals and are not suitable for smaller animals with different movement characteristics, such as tree shrews. In addition, traditional platforms usually cannot dynamically reflect animal behavior and lack intelligent detection and interactive functions, which reduces experimental efficiency and accuracy.
[0003] Therefore, this invention proposes a water maze platform suitable for tree shrews to improve experimental efficiency and accuracy. Utility Model Content

[0029] Reference Figure 1 , Figure 2 , Figure 4 , Figure 9As shown, a water maze platform 1 suitable for tree shrews is provided. The platform 1 comprises a waterproof shell 5, a lifting device located between the platform 1 and the waterproof shell 5, an attitude sensor 9 located at the bottom of the platform 1, a control circuit board 8 located inside the waterproof shell 5, and a battery 7. The control circuit board 8 is electrically connected to the attitude sensor 9, the lifting device, and the battery 7. A wireless communication module 12 is also connected to the control circuit board 8. The attitude sensor 9 is externally protected by a waterproof shell 901, and the attitude sensor 9 is connected to the control circuit board 8 via a waterproof connecting cable 10. In this embodiment, the platform 1 has a diameter of approximately 20 cm and a thickness of 0.7 cm. Tree shrews are 25-40 cm long and weigh 120-250 grams when fully grown; therefore, a 20 cm circular platform 1 with a thickness of 0.7 cm is chosen. To reduce the weight of the platform 1 while ensuring load-bearing capacity, and to better conceal the platform 1, the platform 1 is made of transparent acrylic material.
[0030] Preferably, in this embodiment, the attitude sensor 9 is an MPU-6050 sensor, and the control circuit board 8 is an STM32 microcontroller. The MPU-6050 communicates with the STM32 via the I2C bus. After the MPU-6050 sensor senses a change in the load of the platform 1 and the load change value exceeds a set threshold, the STM32 microcontroller controls the lifting device to lift the platform 1 upward. In this embodiment, the load threshold is more than 100g. In this embodiment, the lifting height of the platform 1 is 1.5-2 cm, and the lifting time of the platform 1 is 2-3 seconds to avoid startling the animals. At the same time, the STM32 microcontroller transmits the lifting time to the host computer or mobile phone through the wireless module.
[0031] Specifically, in this embodiment, the workflow of a water maze platform 1 suitable for tree shrews consists of four steps: detection, control, execution, and feedback. Detection: After the tree shrew climbs onto platform 1, the MPU6050 sensor detects changes in Z-axis acceleration or load. When the load changes to 100g, the control is activated. Control: The microcontroller receives the signal from the MPU6050 sensor and triggers the lifting logic of the lifting device. Execution: The STM32 microcontroller drives the lifting device to slowly raise platform 1. Feedback: When platform 1 rises to a preset position, the STM32 microcontroller keeps platform 1 in the raised state and records the lifting time, transmitting it to a host computer or mobile phone via a wireless module. Simultaneously, 30 seconds after platform 1 rises to the preset position, platform 1 descends to the initial position, and the descent time is recorded and transmitted to a host computer or mobile phone via a wireless module. Setting platform 1 to descend 30 seconds after rising to the preset position is to allow the animal to adapt to and become familiar with the position of platform 1.
[0032] Preferably, in this embodiment, the wireless communication module 12 is a Bluetooth module, specifically a BLE 5.0 module, and the Bluetooth module uses the GTT protocol. Example 2
