摘要
针对分布式无源探测系统中各探测节点组网灵活性、智能化和适应各种地理环境的要求,设计了相应的整套通信系统。该系统包括集GPRS、CDMA和Ethernet 3种网络功能于一体的通信终端,通信终端以LPC2214微控制器为核心,通信单元包括GPRS模块MC55、CDMA模块EM200和以太网芯片W5100。该系统还引入中间服务器作为TCP服务器,实现了作为TCP客户端的通信终端间的数据交换。样机试验结果表明,该系统使用简便,工作稳定可靠。
In order to meet the requirement of the detecting node networking in distributed passive detection system,a communication system was designed. The system included the terminal which combines GPRS,CDMA and Ethernet functions in one set,mierocontroller LPC2214 was used as the core of the terminal,other units like MC55,EM200 and W5100 were used as the communication module. In addition, the intermediate server was introduced to realize the transceiver communication among different terminals. The test results of the prototype show that the system works steadily and reliably,and is easy to use.
