摘要
针对海上石油平台油井压力的实时监控,本文设计了基于CDMA无线通信的远程监控系统,提出了一个可以实现服务器和采集器之间1～N通信的协议,协议通过定时测试连接状态的方法减少了网络不稳定性对系统产生的影响,利用目标采集器的独有的名称而不是其动态的IP地址来识别目标,并且实现了差错控制。对协议性能的分析和现场实验都表明该系统达到了监控系统所要求的实时性和低误码率。
A CDMA based remote monitoring system was designed to realize the real-time monitoring of the pressure data in the oil field on the sea. A communication protocol is proposed to achieve the 1-N data transferring between the administrator and the sensors and the impact of the instability of the wireless network is reduced by testing communication every a predefined time when the network is idle. The destination is recognized by its unique ID instead of the dynamic IP address and the error control is realized. The system is verified by experiments and analysis with the requested target.
