The monitoring assembly includes a sensor 7 disposed on the housing 13 and a sensed element 2 disposed on the tray 1 and sensing the sensor 7.

[0022] The shaking amplitude of tray 1 is first adjusted and determined according to the actual experimental requirements. Specifically, tray 1 is driven to rotate by the drive component, and the rotation position of tray 1 is monitored in real time by the monitoring component. That is, when the drive component drives tray 1 to rotate, the sensed component 2 moves accordingly. The position change of sensed component 2 is sensed in real time by the sensing component 7 to accurately reflect the position of tray 1. When the monitoring component detects that tray 1 has rotated to the designated position, the drive component stops driving, thus determining the shaking amplitude of tray 1. Then, the experimental sample is placed on tray 1 and shaken. The shaking amplitude of tray 1 matches the actual shaking conditions required by the experimental sample, meeting the diverse shaking requirements of different experimental samples.

[0023] Furthermore, the sensing element 7 is a photoelectric sensor, and the sensed element 2 is a light-shielding rod, which is located at the sensing end of the photoelectric sensor.

The output speed and frequency of the power element 6 can be adjusted, and the output speed and frequency of the power element 6 are adjusted according to the actual experimental requirements, that is, the shaking speed and frequency of the tray are adjusted, so that the shaking speed and frequency of the tray are consistent with the actual shaking conditions required by the test sample, and the shaking requirements of different test samples are further met. In addition, it should be further pointed out that the power element 6 uses FOC (field oriented control) closed loop control to realize accurate control of the motor torque and speed.
