摘要
国内水库水位测量大多采用人工测量的方法,或是通过GPRS实现远程监测。人工方法测量存在人身安全问题,测量数据的不准确性,监测的实时性较差等问题,利用GPRS对水库水位远程多点实时监控,功耗、供电等问题造成附加成本较高。系统采用STC89C52微控制器,处理传感器测得的水位数据,通过现场数码管实时显示水位信息,采用低功耗的ZigBee技术实现数据无线远程传输,监控中心通过C#编写的可视化界面实时观测水库水位信息。实验证明系统具有实时性强、数据准确、智能化高、易组网、成本低、便于安装和维护等优点,具有一定的应用价值。
The water level of reservoir is measured by manpower or remote monitoring of GPRS, but some problems like safety, inaccuracy of data and lack of real-time monitoring exist in the manpower measurment, and the remote monitoring through GPRS calls for high power consumption and high cost. The microcontroller STC89C52 is used to obtain the water level data through sensors and display the real-time water level information by digital tube. The low-power technology of ZigBee is ad- opted to realize wireless remote transmission of the data. The monitoring center observe the information of reservoir water level at real time through visual interface programmed with C#. The experiment show that the system has the advantages of hard real time, accurate data, high level intelligentization, fast networking and low cost, and is easy to install and maintain.
