[0015] A control method for implementing the anti-collision control system for a shaking head fan includes the following steps:

[0016] S1. Electrical connection and power-on: The anti-collision control system for the oscillating fan is electrically connected to the oscillating motor through the connection circuit, and then electrically connected to an external power supply. After the connection is completed, the anti-collision control system for the oscillating fan is started through the pin FAN-POWER-ON.

[0017] S2. Driving of the oscillating motor: The control chip U3 outputs a switch control signal for driving.

[0018] S3. Angle data acquisition by the gyroscope processing circuit: The oscillating motor performs an oscillating action. The gyroscope processing circuit senses and collects the angle of the oscillating action and feeds the sensed and collected data back to the control chip U3. When the gyroscope processing circuit detects that the angle of the oscillating motor does not change, it is recorded as the wall-touching limit angle.

[0020] Step S2 further includes the following steps:

[0021] S2.1. The gyroscope in the gyroscope processing circuit is in a zero state at the beginning. Then, when the oscillating motor acts, the gyroscope records the step data of the oscillating motor. When the oscillating motor encounters an obstacle and its angle does not change, the gyroscope processing circuit records the total step data.

[0022] S2.2. The oscillating motor resets and then swings. The gyroscope processing circuit searches again, and the gyroscope processing circuit attenuates the total step data. If the oscillating motor does not encounter an obstacle, the step data recording of the angle is completed. If the oscillating motor encounters an obstacle and its angle does not change, the gyroscope processing circuit repeats steps S2.1 - S2.2 until no obstacle is encountered.
