摘　　要： 为了自动精确称量铝水重量,本文建立了叉车自动称重的数学模型,开发了基于S7-200的叉车自动称重系统。该系统采用拉力传感器采集拉力信号,通过PLC进行称重模型计算,采用TD200显示,使叉车具有搬运与称重双重功能,并能超载报警和自动记录工作情况。应用表明,称重精度达到1％,操作方便、安全,提高了作业效率和管理水平。 In this paper, the weighing model of forklift truck is presented, and a weighing system of automatic forklift truck based on S7 200 is developed, which is used to weigh liquid aluminum from aluminum cell. In this system, the pull detector is employed to collect the signals , PLC dispose it ,then the relative messages are displayed on TD200 text displayer. The system can automatic record the production and alarm while overloading. It is suggested by the application that the design is reasonable and the precision is 1%, it largely improve the efficiency of work and the level of management due to the double functions-conveying and weighing.
