【摘要】 大米抛光机的"闷车"问题一直是众多大米抛光机的一个瓶颈。启动或者关闭顺序不对,或者是在停机时没有同时停水都会导致这种情况的发生。目前这种现象还没有一种很好的解决办法。基于S7-200PLC的智能大米抛光机控制系统,通过对抛光机主作业参数之电流、电压、进水温度以及抛光室物料的检测、采样处理的控制,达到了优化抛光机工作状态的目的。控制系统通过控制机器各个部件的启动和停止顺序,从而达到解决大米抛光机"闷车"问题。实验表明,该抛光机控制系统是有效的。更多还原

【Abstract】 The overload problem is a bottleneck for most rice polishers.The wrong order of starting and halting,or halting without cutting off the water supply at the same time,could lead to this problem.There is no good solution to the problem.The automatic control system for rice polisher based on S7-200 PLC optimized the performance of rice polisher by detecting the main parameters of the rice polisher,including current,voltage and inlet water temperature,and controlling the sampling process of the material in polishing chamber.The system controlled starting and halting order for each component,so the problem above was solved.The experiment results showed that the control system was effective.更多还原
