Abstract
PURPOSE: To improve safety of opening/closing of a door, by transmitting data from an exclusive transmitter and selectively deciphering and releasing only a necessary doorlock in accordance with the transmission time and the number of times in a receiver at an automobile side. CONSTITUTION: A transmitter 1 is constituted of a clock oscillator 11, a transmission data generation circuit 12, a modulation circuit, a high frequency oscillator circuit, 13, etc. Clock signals and ID codes are generated so that respective circuits cope with them. A receiver is constituted of a band-pass filter 22, a high frequency amplifier 23, a transmitting data-demodulation circuit 24, a low-pass filter 25, a converter 26,a microcomputer 27, an actuator 281, etc. Received data are inputted in the I/O port 271 of the microcomputer 27. The system is constituted so that only a doorlock which copes with a transmission time and transmission number of times can be separately released. In this way, only a necessary door lock can be released.
