The action control flow, the power processing unit, the signal processing unit and the output control unit constitute the main control circuit. The power processing unit for supplying power to buck regulator for the power supply of the circuit; the signal processing unit, to accept the power processed by the processing unit to start the internal circuit, and the received signal from the capacitive sensing unit, the program will be compared, editing operation, signal judgment and output signal to the output control unit; a capacitance sensing unit, a body or an object sensing components used to no pressure sensor proximity or contact capacitance sensing unit, and generates a signal input signal processing unit; the output control unit is used to receive the signal from the signal processing unit to start the internal circuit to control the switch from power supply current to the electric telescopic door drive direction; driving device, controlled by the output of the control units and the positive rotation, reverse rotation or linear, |
