摘　　要：基于可编程逻辑控制器的测量与控制技术,设计了水文信息自动测报系统,实现对不同区域的水位与雨量采集测量,并通过GPRS无线通信模块与Inter-net实现组网,把分布在不同现场的水情数据定时传送到水文信息中心进行汇总,实现水文信息的远程测量、监视、报表打印、趋势分析与报警等功能.最后给出的实际测试结果表明了该系统的可行性及精确性.Based on the measuring and control technology of programmable logic controller, an automatic data acquisition system is designed to collect water level and rainfall information in different regions. The system is connected to and communicated with Internet through GPRS module, which can bring all the monitoring data together to the hydrological information center. The system is integrated with various functions such as the hydrological information telemetry, monitoring, report printing, tendency analyzing, and alarming. The actual test results verify the feasibility and accuracy of the system.
