基于PLC定时器的立体车库运车机构准停控制

Accurate stop control of the stereo garage car delivering mechanism based on PLC timer

介绍一种立体车库运车机构准停控制方法,该方法与通常的用接近开关控制电机减速方法不同,而是利用PLC定时器控制电机减速,采用行程开关控制车库运车机构准停。

The paper introduces an accurate stop control method of the stereo garage car delivering mechanism,and the method is different from the common method which uses the proximity switch to control the speed reduction of the motor.The PLC timer is used to control the speed reduction of the motor in the new method,and the travel switch is also used to control the accurate stop of the car delivering mechanism.
