这里介绍的是一种用单片微型计算机模拟导弹遥控系统指令译码解调的电路,它实用于国产某型地空导弹无线电控制探测仪的模拟装置中。该模拟装置由于其该心电路采用了上述单片微型机模拟方案,从而使其电路设备大为简化,模拟效果也较为逼真,同时还可以根据需要为该模拟装置扩展新的功能(如打印、显示等)。本文通过对该导弹遥控系统K_1、K_2指令译码解调原理的讨论,引出了用MCS—48TM单片微机模拟上述译码解调电路的方案,并较详细地介绍了该方案中主要电路的工作情况和程序设计的有关问题。
Described here is a single-chip microcomputer simulation missile remote control system decoding instruction decoder circuit, it is practical for a type of ground-to-air missile radio control detector simulation device. The simulation device uses the above-mentioned single-chip microcomputer simulation scheme for the heart circuit, so that the circuit device is greatly simplified and the simulation effect is more realistic. At the same time, the simulation device can be further extended with new functions (such as printing, Display, etc.). In this paper, we discussed the decoding and demodulation principle of the K_1 and K_2 command remote control system of the missile, and introduced the scheme of MCS-48TM singlechip microcomputer to simulate the above decoding and demodulation circuit. The main circuit Work and program design issues.
