Abstract:
along with the continuous development of city construction, the increasing high-rise buildings.Elevator high-rise buildings as a means of transport in the vertical run has been closely linked with people's daily lives.The traditional elevator control system uses logic of the relay to control circuit, this control easy fault, inconvenient maintenance, operation and short service life, large space occupation, are gradually being phased out.
in order to improve the automatic control system reliability and the work efficiency of the equipments, design a set of PLC and frequency converter as the core controller of the elevator control system, used to replace the complex relay contactor control.The core part of the system (control) using a Japanese Mitsubishi Co production of type FX2N-80MR PLC, because in the core control part is used in software program control, thereby ensuring the normal operation of the elevator in case the requirements, greatly improve the elevator fault inspection and maintenance is convenient and easy, but also overcomes manual the operation brought by a number of factors, and achieved good economic and social benefits.Frequency converter to control the lift during start-stop speed, greatly satisfy people's comfort.On the PLC basic structure of control system and the elevator control system installation and debugging are introduced as follows.
key words: Elevator; PLC; inverter; program design.
