摘要
基于移动通信网络,设计了新型水雨情远程监测站系统。分析了系统的组成和功能需要,完成了以P89LPC954单片机为控制中心的软硬件设计,描述了通过超短波电台、GSM短信独立或组合方式进行数据通信的工作原理,对RS485传感器接口、雨量传感器接口、数据存储器与时钟电路的设计作了详细阐述,并进行了运行测试。测试结果证明,该系统人机界面友好,操作简便,具有良好的传输特性。
The remote hydrological monitoring system based on GPRS technology was studied in this paper. The functions of the system were analyzed and the makeup of the system was given. The designs of hardware and software based on single chip （P89LP954） were given. The design of the sensor interface based on RS485, data storage and clock circuit were elaborated. Under tested in the laboratory and in the actual circumstance, the system shows friend interface, simply operated, and good performance.
