たつもりでも片方が受信していないという事態が
起きる。 Conventionally, when processing is performed using two microcomputers, each microcomputer is provided with a reset circuit to set it to an initial state so that it does not operate until the power supply voltage is stabilized. However, if a reset circuit is provided for each, the reset release time will be different, causing a difference in the microcomputer processing start time of the transmission section and the processing section. The transmission section transfers the data signal communicated with the remote control device to the processing section, so if one of the microcontrollers operates but the other microcontroller is in the initial state, there will be a lag in the processing timing and one side will fail. Even if you intend to transfer the message, a situation may occur where the other party does not receive the message.
このようなタイミングのずれにより動作初期に
無駄な時間を消費し、動作速度の鈍いシステムと

The transmission microcomputer 6, which has been reset by the output signal of the reset circuit 9, outputs a transmission request to the remote control devices 2a, 2b, and 2c, and the remote control devices 2a, 2b, and 2c output response signals to the transmitting and receiving devices. Based on the data signal input to the transmission microcomputer 6 via the demodulation circuit 8, it is repeatedly determined whether the transmitting/receiving device 1 and the remote control devices 2a, 2b, 2c are communicating normally. If it is not normal, the determination is repeated until a predetermined number of times, that is, a predetermined reset time has elapsed. When the required reset time has elapsed, the transmission microcomputer 6 transfers a reset release signal to the process microcomputer 11 via the bus 10b. After transmitting the reset release signal, the transmission microcomputer 6 transfers data signals to and from the process microcomputer 11 via the bus 10b.
