某型遥控系统编码器研制

The development of coder for a remote control system

本文介绍了一种基于频率合成技术的编码器,叙述了该编码器的研制方案及实现方法。该编码器采用89C2051单片机,通过改变参考频率,控制频率合成器产生不同的音频信号,再将这些音频信号按时序要求组合成编码指令。该编码器具有体积小、重量轻、性能优良、形式新颖、成本低廉、使用方便等特点。特别是本文提出的利用单片机为频率合成器提供不同的基准频率从而得到不同音频输出信号的方法,新颖简单、灵活方便。

This paper shows one coder based on frequency synthesis technology, and presents its developing method and working prin- ciple. The coder introduced in this article bases 89C2051 ,which changes reference frequency and control frequency synthesizer which produces different audio frequency signals.These audio frequency signals can be making several orders. The order has the features of small volume, light weight, high performance,unusual form,low cost,easy operation.Especially,the method making signal from reference frequency of single-chip microcomputer is novelty,simple and agility.
