Since it is the first type of spring, all the first springs have the same specification, i.e., the same length and the same spring constant.
S2: arranging an oscillator in the center of one side of the first plate close to the second plate, and connecting the center of one side of the second plate close to the first plate with the oscillator through a second spring, wherein the length of the second spring is smaller than that of the first spring;

Therefore, the second spring is in a tensioned state, and the oscillation transmission effect is better.

However, since the second plate is not fixedly connected to the first plate but elastically connected thereto, the second plate may deviate from the rotational axis of the first plate (centrifugal movement) when rotated, but may be always maintained in parallel with the first plate when rotated due to the same force of the plurality of first springs.
S4: inputting the vibration frequency of the oscillator to enable the second plate to vibrate, and starting the driving motor to drive the first plate to rotate around the axis of the output shaft of the driving motor;

S7: and outputting detection signal curves of the two microwave detectors, the vibration frequency of the oscillator and the rotating speed value of the driving motor to a control center, and decoding microwave contents by the control center.
