当今通讯设备中有无微处理机已是衡量通讯设备先进与否、性能优劣的重要标志之一.给通讯设备配用电脑时,必须综合考虑电脑在通讯设备中的任务,专门为通讯设备设计一系列专用单板机,用于收/发讯机的系统控制.并编制高效的专用软件,从而使通信系统逐步实现智能化和自动化.以下谈谈通讯接收机所用电脑板的软件硬件的设计.一、控制的功能微处理机在通讯接收机中所要实现的功能可大致归纳为:1.数字式频率控制.由面板按键直接选择频率,微机将根据所显示的数字频率值控制频率合成器和VCO以及各个频道的自动切换.2.由按键选择AM、FSK、LSB、USB等工作方式,由微机控制各种工作方式的转换. Today’s communication equipment with or without microprocessors is a measure of the advanced or not, the performance of an important symbol of the pros and cons.When used to the communications equipment with computers, we must consider the computer in the communications equipment tasks, specifically for communications equipment Design a series of special single-board machine for the receiver / transmitter system control and the preparation of highly efficient special software, so that the communication system gradually intelligent and automation. The following talk about the communications receiver computer board software and hardware Design. A control function Microprocessor communication receiver to be achieved in the function can be summarized as follows: 1. Digital frequency control. By the panel keys directly select the frequency, the computer will display the digital frequency value under the control of frequency synthesis VCO and the various channels and the channel automatically switch .2 by the key to select the AM, FSK, LSB, USB and other work methods, controlled by the computer a variety of work-style conversion.
