Nowadays,the manufacture capability and using quantity of elevator is one of the symbols of national modernization degree.Especially,along with urban population increase and people’s corporeal life quality have been raised greatly,architecture field develop rapidly that a large of high building and large mansions appear as if bamboo shoots in spring come out of ground after raining.The elevator has been playing a key role in our life such as production working and daily life.Therefore,study on elevator is much more significant.
People never stop study on elevator.On theory,elevator controls system had gone through three phases that from relay-connector control to PLC control and then Computer control.Inactual engineering design in our country,PLC is popular applied in virtue of its advantage such as high-reliability,excellent anti-jamming ability,strong function,wonderful expansibility and low cost etc.
This paper mainly does a research on elevator control based on PLC, Firstly,the main construction and control requirement of elevator is analyzed;the PLC program is designed.Secondly, the elevator model system is designed by MCGS configuration software. Finally, admiting plc as lower computer meanwhile the configuration system is simulated by PLC。As a result ,we can control the real elevator model in ourlifies。This technique is significant to the more research on elevator control and industry spot monitor.
