摘　　要：针对无线电遥控系统抗干扰能力差、稳定性不高等缺点，提出了可靠性较高的简易无线电遥控系统的工作原理和设计方法。其中，发射部分采用电容三点式振荡改进型的西勒电路产生调制信号；接收部分按超外差方式组成，完成解调信号恢复电路的设计。理论与实践表明，该设计思路新颖，方案可行，可实现短距离遥控。According to the disadvantages of the bad anti-interference ability and the poor stability of the radio remote control system, this paper proposed the working principle and design method of the simple radio remote control system with high reliability. Among them, the emission part adopted the Schillel circuit of the improved three-point capacitance oscillator to generate modulation signals. The receiver part was form in accordance with super heterodyne and completed the design of the demodulation signal recovery circuit. Theory and practice shows that the design idea is novelty, the scheme is feasible. And it can achieve short remote.
