The invention discloses a tower crane anti-swing automatic control system, which relates to the technical field of motor control, and comprises a power supply rectification protection frequency conversion module used for rectification, protection and inversion frequency conversion control; the function control module is used for outputting a control instruction through the touch screen circuit; the swing detection module is used for detecting the swing degree of the hoisted object; the intelligent control module is used for receiving the signal and controlling the module to work; the sampling, holding and comparing module is used for holding the swing signal and carrying out threshold comparison; the pulse control module is used for generating and adjusting a pulse signal; and the motor control module is used for adjusting the motor speed. According to the tower crane anti-swing automatic control system, the function control module provides a control instruction for the intelligent control module in a touch screen circuit mode so that up-down and left-right control can be carried out, meanwhile, real-time monitoring and real-time comparison judgment can be carried out on the swing degree of a hoisted object, the conduction degree of the motor control module is determined according to the magnitude of swing force, and therefore the swing degree of the hoisted object can be controlled. The working speed of the motor is controlled.

    本发明公开了一种塔机防摇摆自动控制系统,涉及电机控制技术领域,包括电源整流保护变频模块,用于整流、保护和逆变变频控制;功能控制模块,用于通过触摸屏电路输出控制指令;摇摆检测模块,用于检测被吊物的摇摆程度;智能控制模块,用于接收信号并控制模块工作;采样保持比较模块,用于保持摇摆信号并进行阈值比较;脉冲控制模块,用于产生和调节脉冲信号;电机控制模块,用于调节电机速率。本发明塔机防摇摆自动控制系统由功能控制模块采用触摸屏电路的方式为智能控制模块提供控制指令,以便进行上下左右控制,同时对被吊物的摇摆程度进行实时监测和实时比较判断,由摇摆力的大小决定电机控制模块的导通程度,控制电机的工作速率。
