摘要
介绍一种比例遥控收发机的设计与实现方法。在发射机中,四个摇臂变阻器中心抽头输出的电压信号经ADC0808转换为数字信号送入单片机,经单片机处理后加载到315MHz射频发射模块向外发射。接收机中的接收模块将收到的指令解调后以TTL电平送往单片机串口接收,在单片机内经译码等处理后控制相应的执行机构执行指定操作。该收发机引入单片机,使遥控可以更灵活,且扩展方便,成本较低。
The design and effectuation of a remote-controlled transceiver is interpreted. There are four voltage signals outputted from the center taps of four corresponding rocker rheostats in the transmitter, they are converted to digital signal by ADC0808, after the digital signal is processed by a single-chip microcomputer, and it is loaded to a RF launch module with 315 MHz and launched out. The instruction information received by the receiving module is demodulated and sent to the serial port of the receiving single-chip microcomputer with TTL level . The executing agency is operated according to the instruction. The single-chip microcomputer used in this remote-controlled transceiver makes the remote control flexible, and expand conveniently with low cost.
