摘　　要：设计了一种基于单片机的低功耗水情遥测终端,实现多种水情数据的采集、处理和报送。终端采用AT89S52单片机作为硬件核心,由扩充存储器、实时时钟、键盘输入、液晶显示、串行通信、调制解调及太阳能供电等外围电路构成。同时具备数字和模拟数据采集接口,通过连接相应传感器,实时采集雨量、水位、闸位、流量、温度等信息,使遥测参数多样化。显示模块与按键配合,用于动态显示、设置参数及系统的检测维护。设计的RS-232通信接口,可连接SMS/GSM、GPRS、无线电台等通信模块,满足不同通信方式下的应用,提高了通用性。该终端在实际应用中亦能稳定可靠地工作,满足水情遥测的功能和性能等技术要求。A low power remote terminal unit for water regime information based on single chip was designed, which implemented acquisition, processing and transmission of various hydrological data. The system was composed of AT89S52 and peripheral circuits such as memorizer, real time clock, keyboard, LCD, serial communication, modem, solar power supply, etc. The system had digital and analog data acquisition interfaces, and acquired diversified parameters such as rainfull, water level, water gate position ,flow, temperature and so on by connecting corresponding transducers. LCD and Keyboard were used together to display and set parameters, and to test and maintain the system. The communication interface of RS-232 connected different communication modules which included SMS/GSM,GPRS and digital transmitter-receiver. As a result, the system is suitable for different communication environments and improves the generality greatly. The system works reliably and stably in actual application, and meets the requirements in function and performance.
