In this paper,an automatic filling system based on AVR control unit design. The design of automatic filling system, the choice of software and hardware, and so on are given in detail by means of automatic control thought method. The system uses 8-bit processor,the voltage sensor signal acquisition,conversion,and finally through the dig-ital filter processing,the results will be displayed on the LCD,the control signal sent to the implementing agencies to control the filling system action. The simulation results show that the system has good self-practicability,strong robust-ness and reliability,and can be integrated in a variety of filling environments,and has broad market prospects.%提出了一种基于AVR的自动灌装系统控制单元设计方案.利用自动控制思想方法对自动灌装系统的结构设计、软硬件选择等给出详细的解决方案.系统采用8位处理器,对称重传感器的电压信号采集、转换,最后通过数字滤波处理,将处理结果显示在LCD上,将控制信号发送给执行机构控制灌装系统动作.仿真实验表明该系统具有好的自实用性和强的鲁棒性、可靠性,能够集成在多种灌装环境中,具有广阔的市场应用前景.
