摘要
为解决异构测控网络的以太网接入问题,以ARM9处理器S3C2440A和多个功能模块组成硬件平台,在移植嵌入式操作系统Linux和嵌入式数据库SQLite3的基础上,设计了多线程网关服务程序,实现了兼容无线数传、通用串口、WiFi等通信方式的以太网接入。测试结果表明:该网关具有成本低,兼容性强,使用方便等特点。
In order to solve the problem of Ethernet access in heterogeneous measurement and control network,by taking ARM9 processor S3C2440A and several functional modules to form the hardware platform,a multithread service program for gateway was designed,and Ethernet access compatible with the multiple communication modes such as WSN,universal serial port and WIFI was realized based on transplantion of the embedded operation system Linux and embedded database SQLite3. The test results show that this gateway has the characteristics of low cost,strong compatibility and convenient application.
