Integration of elevator control systems

Elevator automatic control system has become a computer technology applications in the field has a very dynamic branch. In order to meet the high requirements for the flexibility, reliability and functionality of the system, the developed system is based on microcomputers. This system is a 4C technology, namely, computer technology (COMPUTER), automatic control technology (CONTROL), communication technology (COMMUNICATION) and conversion technology (CHANGE) into a highly related, integrated system. It has obvious superiority in the control range, adaptability, maintainability, system stability and so on, and has become the cornerstone of the development of elevator control technology. System stability and many other aspects of the previous control system has obvious advantages, and has become the cornerstone of the development of elevator control technology.

Elevator speed tends to ultra-high speed

With the mass of skyscrapers, the elevator running speed constantly challenge, but also to promote the development of elevator technology. At present the world’s highest speed of the elevator has reached 17m / s, more 18m / s elevator will run in more than 600 meters high “Shanghai Center Building”. Can be expected, with multi-purpose, full-featured high-rise building development, ultra-high-speed elevator will continue to be the direction of research and development. Large capacity traction motors, high-performance microprocessors, vibration reduction, noise suppression technology, car automatic pressure control system, suitable for ultra-high-speed elevator safety components and other technologies will be actively promoted.

The popularity of green elevators is an inevitable trend

Energy-saving, environmentally friendly materials in the elevator parts on the application has been exposed. Permanent magnet synchronous gearless traction machine, energy feedback device is rapidly improving the machine matching rate. Non-metallic materials made of car wall, guide wheel, traction wheel has been put into use. The elevator suspension system replaces the traditional traction wire rope with a flat composite traction strip. The use of non-metallic materials made of rope to replace the rope is more revolutionary. In addition, the use of linear motor-driven elevator also has a larger research space. The two elevators that share the same hoistway are already running. Elevator group control system more intelligent. Such as expert system, fuzzy logic group control system can adapt to the elevator traffic uncertainty, control the diversity of objectives, non-linear performance and other dynamic characteristics. With the development of intelligent buildings, the intelligent group control system of the elevator can be combined with all the automation service equipment of the building into the whole intelligent system.
