摘要
传统的电子信息处理主要是以CDMA网络,或是GPRS网络构成的单机系统为主。在待处理数据量大时,会导致传输通道堵塞,影响传输速率,为此提出基于GSM模块的电子信息双机自动化处理系统设计。在双机硬件冗余技术容错的基础上,设计采用串行异步通信接口连接的GSM硬件模块,完成硬件系统的构建。与此同时,选择基于C++语言的IAR软件开发工具,实现双机嵌入式程序的集成开发环境;并利用GSM模块网络建立不同信道传输电子信息,进而通过空气接口实现双机自动化处理,实现软件系统的构建。根据实验对比结果可知,在考虑网络覆盖率,以及单机或双机处理的前提下,基于GSM模块的电子信息双机自动化处理系统传输速率最快,达175.93 kb/s。
The traditional electronic information processing system is mainly composed of CDMA network or GPRS network;When the amount of data to be processed is large,the transmission channel will be blocked and the transmission rate will be affected.Therefore,the design of electronic information dual computer automatic processing system based on GSM module is proposed.Based on the fault tolerance of dual computer hardware redundancy technology,the GSM hardware module connected with serial asynchronous communication interface is designed to complete the construction of hardware system.At the same time,the IAR software development tool based on C++ language is selected to realize the integrated development environment of dual computer embedded program;The GSM module network is used to establish different channels to transmit electronic information,and then the air interface is used to realize the dual computer automatic processing,and the construction of software system is realized.According to the experimental results,considering the network coverage and single or dual computer processing,the transmission rate of the electronic information dual computer automatic processing system based on GSM module is the fastest,up to 175.93 kb/s.
