摘　　要：水源地信息采集装置是以STC12C5A60S2单片机为核心控制器,主要完成水压、水量、电机温度、电机转速以及电量等信息的采集。水压、水量、电机温度等信息通过AD芯片交给单片机进行分析处理,电机转速信息通过脉冲信号直接通过单片机采集,而电压、电流等电量信息采用智能电量模块通过RS485接口与单片机进行通讯。水源地信息采集装置采集数据准确,而且设计了扩展电路,能和泵房、上位机系统进行数据连接和交流。It is mainly to collect water pressure, water volume, motor temperature, rotating speed, power and other information. Water pressure, water volume and the motor temperature were analyzed through AD chip to MCU processing, motor speed was collected by the pulse signal directly through single chip microcomputer, and power information such as voltage used intelligent power module to communicate with MCU via RS485 interface. This device completes the collection of some basic information and collect data accurately. With the expanded circuit, it could do data connection and communication with pump room and upper machine systems.
