摘要
该文研制了一种高性能的液体转移监控系统,该系统采用AD7705型∑-Δ模数转换器,对称重传感器的微弱电压信号进行放大并数字化处理,使用ATmega16单片机进行PID控制,输出PWM信号到直流水泵驱动电路板,用以调节直流水泵的给水量,最后实现容器中液面的动态平衡,该系统可广泛应用于液料的定量转移。
A high-performance system of liquid transforming and monitoring was designed. By used AD7705 ∑-Δ analog to digital converter to amplify and digitalize the micro-signal come from pressure sensor,and complete the PID control algorithm in ATmega16 micro-control unit,then ATmega16 output the PWM signal to circuit board of directcurrent pump driver order to regulate the quantity of water rejecting. This system could maintain the dynamic balance of liquid surface,so it could be widely used in transforming of liquid material in factory.
