[0098] Normally, each unit is in a waiting state.

[0099] 2) When the user needs the electric pressure plate to open or close, a remote control command needs to be sent to the pressure plate through the communication network. The communication unit directly connected to the communication network first receives the command signal. The communication unit converts the remote control command level and format on the communication network into a level and format recognizable by the processing unit and transmits it to the processing unit.

[0100] 3) After the processing unit receives the remote control command from the communication unit, it first identifies whether the command conforms to the preset format. If it does not conform to the preset format, it is considered to be an invalid command and discarded. If it conforms, it controls the corresponding unit (motor unit and status detection unit) to perform actions or conduct detection based on the command content and the current system status.

[0101] 4) If the processing unit receives a rotation instruction for the drive motor (the instruction has only two types: turn to the open position / turn to the closed position), it first reads the status detection unit to obtain the position of the transmission shaft. If the transmission unit is not currently located at the open position / closed position target position to be operated, it is determined that the motor needs to rotate to the position to be operated. The processing unit sends a start signal to the drive unit, which is converted by the drive unit into a motor drive current to drive the motor unit, drive the transmission unit and the pressure plate spring unit to rotate toward the target position; at the same time, the processing unit continuously reads the status information of the status detection unit. If it is recognized that the transmission unit has rotated to the target position, the status information changes to open position in place / closed position in place, and the processing unit sends a stop signal to the drive unit to stop the motor unit from working and drive the transmission unit and the pressure plate spring unit to stop rotating. If the transmission unit is currently located at the open position / closed position target position to be operated, it is determined that the motor does not need to rotate to the position to be operated, and the processing unit does not send a start signal to the drive unit.

[0102] 5) If a status acquisition instruction is received, the processing unit reads the status detection unit to obtain the position of the transmission unit, and determines whether the current reed is in an open position / closed position / abnormal position based on the read status. The processing unit converts the status into data in a preset format and sends the status data to the user through the communication network via the communication unit.
