摘要
介绍了一种专用编码和译码的多路遥控指令的发送系统.该系统以键控计数译码、数据选择、环形延时标定、编码、振荡分频、门控及载频放大电路为核心电路.电路设计巧妙,实用性强,适用范围广.长期实际运行证明,该系统十分稳定可靠,达到了原设计的各项技术指标要求.
special codinganddecoding transmitting system with multichannel remote control commands is introduced in this paper.Its key circuits are the keying decoding circuit,data selector circuit,ring timedelay demarcation circuit,coding circuit,oscillating frequency demultiplier circuit,control system circuit and carrier frequency amplifier circuit.The circuits have clever designs,strong practicability and wide application range.The longterm practice has proved that the system was very stable and reliable,and accorded with the demands of technical indices in the original designs.
