A new type monitoring system of water regimen is designed by using current popular ARM9 processor and GPRS technology to achieve hardware of poor scalability, single function and data transmission. The system can effectively overcome the many shortcomings to the use of traditional wired transmission, such as lines of difficult, overcome the shortcomings of not strong, secondary development and upgrading of inconvenient by through the ARM9 processor instead of microcontroller. The preliminary result shows that the system owns such advantages as high reliability, scalability, testing accuracy, being used easily and so on. The technology and methods adopted in the system are practical.%针对目前我国水情测报系统的硬件可扩展性差、功能单一和数据传输方式不便的问题,采用ARM9处理器和GPRS技术,设计了一种新型的水情测报系统.该系统充分利用现有的GPRS技术实现现场的遥测站与数据中心之间的信号传输功能,有效地克服了以往系统中数据传输采用有线传输方式(如架线困难等)的多种缺陷；通过ARM9处理器代替单片机,克服了以往系统性能不强大、二次开发和升级不方便等缺点.实际应用表明,该系统可靠性高、可扩展、检测精确、维护方便,具有一定的实用性.
