Description: 毕业设计时制作的一套水位遥测自控系统,本系统以AT89S51单片机为主控单元，通过超声波传感器和液位变送器实现液位实时数据的检测和自动控制。系统分主控站与测控站，通过主控站的键盘可以实现对测控站的水位上下限的控制和显示。主控站与测控站之间的无线实时数据传输的解决方案采用广泛应用于无线抄表、工业数据采集系统和水文气象监控等领域的无线通信芯片nRF24L01组成无线高速数据收发模块。系统实现对所监控水位的短矩离无线测量与自动控制，利用GFSK实现数据高速传送以及较低的功耗。从测控站传送过来的数据通过人性化人机交换界面LCD1602实现数据的实时数据显示以及实现相应的报警提示。本系统通过单片机串口与电脑串口的通讯功能和利用互联网可以实现水位的远程测量与自动控制，这对江河水位的实时监控非常实用。本系统可能通过简单地调整就可以移植到其它物位系统与无线抄表系统，非常有研究价值。系统利用功能强大的C语言开发，并在软硬件设计中分别使用了Protel 99se 、keilC51开发平台。结果表明，该系统具有有性价比高、操作简便、可视化操作等优点.-The system main control unit MCU AT89S51 by ultrasonic liquid level sensors and liquid level transmitter implementation of real-time data detection and automatic control. System sub-master control station and the monitoring and control station, through the master control station s keyboard can be achieved on the water level monitoring station on the lower limit of the control and display. Master control station and the monitoring and control station in real time between the wireless data transmission solutions are widely used for wireless meter reading, industrial data acquisition systems and hydro-meteorological monitoring in areas such as wireless communications chip component nRF24L01 wireless high-speed data transceiver module. System monitoring the water level on the implementation of the short moments away from the wireless measurement and automatic control, the use of GFSK achieve high-speed data transmission and lower power consumption. From the monitoring station to send back
