摘要
针对停车场管理系统,设计了两种通信技术之间直连网关。采用Zigbee与计算机融合的通信技术,满足了车辆管理、医院监护和智能家居等远程监控领域的个性化需求。对网关的串口通信模块和网络通信模块进行了分析,并详细介绍了在Linux操作系统环境下的串口编程和基于TCP/IP协议的Socket网络编程及通过ARM控制的GSM短信模块,实现了远距离实时报警。本网关通过Select监控机制实现了串口数据流和以太网的数据流的同步转换。
A new direct-connection gateway between the two communication technologies is proposed and designed for parking management system. By integrating communication technology with Zigbee and computer, the proposed gateway could meet the demands of vehicle management, hospital care, smart home and other individual demand for remote monitoring. Serial communication module of gateway and network communication module are analyzed, and serial programming under Linux operating system environment and Socket network programming based on TCP/IP protocol also described in detail. With the Select monitoring mechanism, the novel gateway could realize the synchronous conversion of between serial data flow and Ethernet data flow.
