Abstract
Escalators are widely used in hotels, shopping malls, subways, train stations, office buildings, airports and other places, in the convenience of our customers and improve service quality has played a very important role. The design uses a PLC control system with high reliability, good stability, programming is simple, easy to use, easy to repair and maintenance and other significant advantages. The PLC is applied to the escalator, can greatly improve the level of control of the escalator, escalator reached the control effect is more ideal. Compared with relay control escalators have a qualitative leap. It enables computerized control of the escalator, escalator more intelligent. Escalators by servo drive, Y-Δ switching activation. From the safety requirements and inspection requirements to run the elevator starting, taking into account the convenience of the elevator operation, the program primarily designed to achieve three operating states: automatic operation, manual operation, maintenance operation. Under normal circumstances, the escalator into the automatic operation; when a particular situation occurs when the escalator in the role of external hand signals, enter manually run the state, when the system maintenance, overhaul insert the cartridge into the maintenance state. After the electrical system components, in order to achieve optimal control, the control program needs careful preparation of the PLC. In the PLC control program needs to be treated first and foremost safety circuit logic signal detection signal, by processing of these signals, given the appropriate operating status display and alarm signals
