Abstract

In the remote control system that controls the operation of the main body by inputting a key signal from the remote control, the remote control system transmits information between the main body and the remote control by FM signal, separates setting data and execution data for hourly main body control, and sends and receives The main body of the microcomputer is equipped with a memory function for controlling and the current time recognition function, and the remote control system having a function to view the operation status of the main body on the remote control unit, so that the user can fix the direction and position within a predetermined distance. You can control the operation of the main body with the remote control without programming, and you can control the various functions of the main body at that time by programming the control data for each time zone. In addition, there is an effect that can know the operating status of the main body on the remote control.
