Design of induction electric door control system based on PLC
Abstract:With the social and economic development and progress, induction automatic doors have been gradually applied to large-scale companies, scientific research institutions and other high confidentiality of the unit.In order to strengthen the reliability of automatic door operation, the design is based on PLC as the basis of control, combined with pyroelectric infrared sensor and inverter control sensor automatic door control system.The design of PLC as a controller to improve the automatic door control system optional, can handle the automatic door switch control and good stability, at the same time can easily change the control mode.

Key words:PLC;Reliability;Frequency conversion control
