摘要
针对分布式无源探测信息融合系统中各探测站与融合中心组网通信要求,构建了一套基于CDMA网络的收发系统,满足在各种地理环境下的使用需求。以LPC2214为控制核心结合CDMA模块EM200构成了该系统的收发终端,针对其中发送端存在的问题给出了硬件解决方案,并结合实时操作系统分别阐述收发端软件架构。此外还引入中间转发平台用作TCP服务器实现作为TCP客户端的收发终端间的数据交换。与传统GPRS方案相比,该系统低延时的特性使其更适合实时性要求较高的分布式信息融合系统的需求。
For the network communication of distributed passive detection information fusion system, a transceiving sys- tem based on CDMA network has been set up to meet the requirement of using in various geographic environments. The transceiver terminal is mainly comprised of LPC2214 and EM200 module. A hardware solution is provided to solve the prob- lems existed in transmitting terminal. The software structure of transceiver terminal with real-time operating system is ex- pounded and the intermediate transmitting platform is introduced to realize data exchang among different terminals of TCP client. Compared with the traditional GPRS scheme, this system is more suitable for the high demand of real-time performance in distributed information fusion system.
