Integration of elevator control systems
The elevator automatic control system has become a very dynamic branch in the field of computer technology applications. In order to meet the high requirements for system security, reliability and functional flexibility, the system developed is based on a microcomputer. This system integrates 4C technology, namely COMPUTER, CONTROL, COMMUNICATION and CHANGE, into a highly correlated and integrated system. It has obvious advantages over previous control systems in terms of adaptability, scalability, maintainability, system stability and so on, and has become the cornerstone for promoting the development of elevator control technology. Many aspects such as system stability and stability have obvious advantages over previous control systems, and have become the cornerstone for promoting the development of elevator control technology.
Elevator speed tends to be ultra-high speed
With the grouping of skyscrapers, the speed of the elevator is constantly challenged, and the development of elevator technology is also promoted. At present, the maximum speed of elevators in the world has reached 17m/s, and the elevators with 18m/s will be operated in the “Shanghai Tower” of more than 600 meters. It can be expected that with the development of multi-purpose, full-featured super-tall buildings, ultra-high-speed elevators will continue to be the direction of research and development. Technologies such as ultra-large capacity traction motors, high-performance microprocessors, vibration reduction, noise suppression technology, automatic pressure regulation systems in cars, and safety components for ultra-high-speed elevators will be actively promoted.
The popularity of green elevators is an inevitable trend
The application of energy-saving and environmentally-friendly materials in elevator parts has already begun to emerge. The permanent magnet synchronous gearless traction machine and energy feedback device are rapidly improving the matching rate of the whole machine. Car walls, guide wheels and traction sheaves made of non-metallic materials have been put into use. The elevator suspension system replaces the traditional traction wire rope with a flat composite traction steel belt. The replacement of wire ropes with sling ropes made of non-metallic materials is more revolutionary. In addition, elevators driven by linear motors also have a large research space. The twin elevators where the two elevators share the same hoistway have started running. The elevator group control system is more intelligent. For example, the group control system based on expert system and fuzzy logic can adapt to the dynamic characteristics of elevator traffic uncertainty, control target diversification and nonlinear performance. 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 an overall intelligent system.
