2 common features of China Passenger Elevator :
1. The advancement of elevators is mainly reflected in the aspects of drag and control technology. With the development of power electronics technology and computer technology, there has been fundamental progress. The vector control frequency regulation, voltage regulation, and speed regulation technology make the speed regulation performance of the AC asynchronous motor. It has reached the level of a DC motor, and the logic control system using a computer is replacing relays and increasing the control function of elevators. The application of network control and fuzzy control theory makes elevator dispatching control develop in an intelligent direction.
2. Comfort mainly refers to the acceleration, vibration, noise, decoration, lighting, and other indicators of the elevator, and its purpose is to provide passengers with a comfortable riding environment as much as possible. The early comfort requirements are mainly to control the overweight and weightlessness, annoying noise, and anxiety within the range that passengers can tolerate; the modern comfort is to make passengers take the elevator as an enjoyment not only physically but also psychologically.
