基于无线电台的电话延伸系统

现阶段在我军的边防部队装备有大量旧式模拟制无线电台,这些电台的信号质量较差,接口功能有限,无法满足部队对通信的要求。本系统通过研制扩展接口设备,将电话网通过无线电台延伸到值勤巡逻分队,使指挥员可通过电话与一线外出分队直接通信。通过使用PIC18F8720微处理器和DSP芯片实现了这个接口设备,从试验仿真和结果来看,达到了研制目的,并且研制出了样机交付部队使用。

Extended Telephone System with Wireless Terminal

Currently,large amount of old type wireless communication terminals are in service in the frontier army.These terminals that offer poor communication quality and limited interfaces can not satisfy the requirement of the army.The aim of this system we developed is to extend the military telephone network with these old type wireless terminals,so that the officers can communicate directly with the parols.In this article,using the PIC18F8720 microprocessor and DSP chip,the interface is achieved.From the simulated and resulted,the aim is also got.At the same time,the module machine has also used in the army.
