Title:
REMOTE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP3143249
Kind Code:
B2
Abstract:
PURPOSE: To reduce electric power consumption of a battery by arranging an intermittent power supply means and a power supply ON and OFF switching means in a receiver operated by receiving a radio wave signal from a transmitter, and switching these to/from each other according to a condition.
CONSTITUTION: A ROM15a and a RAM15b to store fixed/variable data are arranged in a CPU15 of a receiving device, and a receiver 17 having an antenna 16 is connected to a battery 25 through the CPU15, a DSP18, an operation box 19, a door lock driving motor 20, a timer circuit 21, an A/D converter 22, an SRAM24, a switch circuit 28 and a pressure reducing circuit 26. The receiving device is put in a power unsupplied condition at initial time of operation, and next, is put in a condition of power supply from an electric power supply part 27 for prescribed time by the CPU15, and these are repeated. The device is restored to continuous power supply at ON time of an electric power supply closing condition signal, and to intermittent power supply at OFF time, and when an ON signal continues for not less than constant time at continuous power supply time of the receiving device, it is restored to the intermittent power supply. Thereby, electric power consumption of the battery 25 can be reduced, and a dead condition of the battery can be prevented.
