针对起重机在工作中作业效率不高、操作人员易疲劳、故障率高等问题,设计了一套起重机高速频率控制和实时起重量协调运行的系统,本系统将PLC、传感器、变频器、网络等结合到一起。PLC把信息采集单元采集的实时起重量、行程等信号计算并输出控制信号给变频器,变频器在速度步期间计算相应速度,输出相对应的工作频率,使起重机运行机构协调工作,从而使起重机更具智能化。
Aiming at the problems of low work efficiency, easy fatigue of operator and high failure rate of crane, a system of crane high-speed frequency control and real-time crane weight coordinated operation was designed. The system combined PLC, sensor, inverter, network and so on Together. PLC real-time information collected by the acquisition unit to collect weight and travel signals and other control signals calculated and output to the inverter, the speed of the inverter during the calculation of the corresponding speed, output the corresponding operating frequency, so that the crane operating agencies to work together so that the crane More intelligent.
