| Abstract: | 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. |
