The Design of The electrical Control Parts of Automatic Gate
Based on PLC
Abstract
The configure of a automatic control system of automatic gate and the structure of its control system are presented in this paper.It pays more attention to the method using PLC and frequency inverter to control the automatic gate.The center controller passes with various conjunction that spreads the feeling machine( defend to clip, defend to bump to spread the feeling machine, the infrared ray responds to spread the feeling machine, nearing to the switch to spread the feeling machine), carry out a system of automatic underway stop, automatic fixed position, adjust soon the function and nighttimes shut the lock etc. function, then carry out the safe credibility control of a system.This text still introduces the software design of the system and adjusts to try, and give a form of language procedure of the system.
