PURPOSE: To eliminate the need for wiring works by installing a transmitter modulating and transmitting a detecting signal from a sensor and a receiver demodulating a modulation signal and transmitting and receiving a signal between the sensor and a controller opening and closing a power door by wireless. CONSTITUTION: Sensors 1A, 1B detecting the intrusion and retreat of a person, a transmitter 6 modulating and transmitting a detecting signal, a receiver 7 a demodulating a modulation signal and obtaining a control signal and a control section 5 are mounted on the titled device. When the sensors 1A, 1B detect the person, the detecting signal is transmitted to the transmitter 6, and the transmitter 6 modulates the detecting signal and transmits it to the receiver 7. The receiver 7 demodulates a modulation signal and the original detecting signal is obtained, and the control section 5 of the power door is driven. The signal is transmitted and received by wireless among the sensors 1A, 1B and the control section 5. Accordingly, the wiring works of signal conductors can be made unnecessary. |
