Design of Control System of New Scissor Lifting Platform Based on PLC
In view of the previous scissor lifting platform is basically hydraulic cylinder drive can not achieve accurate control positioning,it is difficult to meet the requirements of automatic production line for accurate control of lifting height,now to step motor drive and syn-chronous belt drive,to improve the positioning accuracy of the lifting platform,and overcome the shortcomings of the traditional hydraulic system.The pulse number and pulse frequency of the stepper motor are controlled by PLC to realize the rise and fall,and a closed-loop control system integrating real-time monitoring and measuring platform height is formed.In addition,parameters and real-time display are set on the man-machine interface to meet the needs of different application scenarios.
