摘　　要：针对目前中小型水电站及水库坝体的安全监测系统自动化程度不高的问题,设计了基于ARM9嵌入式系统的网络化监测系统,并分析测试了监测系统网络化可能带来的数据传输实时性问题。系统采用数据采集终端和处理中心相分离的模式,实现了现场传感器、上游水文站以及上位监控系统之间数据的网络化传输,而且使得数据采集器的小型化和便携式成为可能,特别适合应用于监测点不太多的中小型水电站及水库坝体的安全监测。At present,the automation level of the safety monitoring system for small-and-medium-sized hydraulic power stations and reservoir dams is quite low,thus the safety monitoring system based on ARM9 embedded system has been designed.The real-time performance for data transmission affecting by networking of the monitoring system is analyzed and tested.The system adopts separation pattern for the data acquisition terminals and processing center,this implements the networking data transmission among field sensors,upstream hydrometric stations,and host computerized monitoring system;and makes the data collector compact and portable,it is most suitable for small-and-medium-sized dams of hydraulic power stations with not too many detected points.
