electromagnet overhead crane control system in the crane size vehicle control principle

This article will introduce the electromagnet overhead crane control system in the crane size car control principle:
SCM central processing system, real-time status and position information gathering work of the master switch, the central processor via the control unit for information processing, the use of 485 to achieve information from the control unit to the execution unit of transmission, thus completing the electromagnet overhead crane size car motor control, and then realize shipbuilding gantry crane left and front right information and the car stalls, control, rear and gear information.The size of the vehicle control system panel is shown in two shows:
Mute switch: turn on the switch, turn off the sound travels carts; turn off the switch, turn on the sound travels carts;
Hammer instructions: Tips reached the limit height;
Hammer Reset: height when it reaches the limit, use the hammer reset button in special circumstances can lift limit increase;
Operating lever: front push each car five stalls, each pushing carts around five stalls, to the execution unit can transmit different instructions;
Phase voltage switch: Turn the switch can adjust voltmeter shows AB, AC, BC, the voltage value of any two phases.
