| 摘 要： | 针对各种实时数据采集传输的需要,设计和实现基于通用分组无线业务(General Packet Radio Service,GPRS)网络的远程数据采集传输系统.该系统使用RS-232接口读取外部数据,如果GPRS网络或GSM(Global System for Mobile Communication)网络可用,则以GPRS通信或短信方式将数据发送到数据中心,否则将数据存储在外部存储器中.介绍该系统软件设计和实现中的关键技术,包括网络协议栈的实现和网络地址转换(Net Address Translation,NAT)设备的穿透.该系统已经应用到某车载监控终端系统和远程抄表系统中,且运行稳定高效.

| Abstract: | To satisfy the requirement of real-time remote data acquisition,the remote acquired data transmission system based on GPRS is designed and implemented which receives data through a RS-232 port.If the GPRS network or GSM network is available,the data are sent to data center,or otherwise they are stored in the storage.The key techniques in design and implementation of the software are introduced which include the implementation of the network protocol stack and Net Address Translation(NAT)device traversal.The system is applied in supervision system by vehicle terminal and remote metering system,and achieves good stability and high efficiency. |
