基于GSM的专用数字无线通信系统手持终端软件主体逻辑的设计与实现

目前国内专用无线通信系统多为模拟方式,通信工具功能单一,比较落后.为适应发展,迫切需要开发一种新型的功能完备的专用数字无线通信系统.GSM网络不仅可以作为无线通信的公网使用,还可以在此网络基础上开发专用的通信网络及相应的通信终端,满足特定领域的语音和数据通信要求.本文结合基于GSM网络的专用数字无线通信系统终端的实际开发经验,介绍了专用无线通信系统对手持终端功能上和总体设计上的要求,对其基本功能要求进行了阐述,随后重点介绍了手持终端中基于8051F单片机的主控制单元的主体程序开发,并给出相关框图.

Design and realization of the main logic for special digital wireless communication terminal based on GSM

Nowadays,the special wireless communication systems used in China are somehow out of date.It is rather significant to develop a new kind of digital wireless communication terminal to fulfill the need of users.GSM network can not only be used as common communication network,but can also be used as a basic network on which special network and terminal are developed.According to the experience in the development of the new wireless communication system which is based on the GSM network,the article first introduces this communication system's demands that the terminal should has in function,and illustrates the basic functions,then expatiates on the main program of the central control block which is based on 8051F microprocessor.Some important charts are also presented in the article.
