【 Weak current College 】 elevator monitoring and intelligent building technology development trend analysis---Power By 【 China power house network 】

At present, China's intelligent building elevator control and power relations between
　　
Experienced a 100-year history of the elevator is already familiar with important buildings, equipment, modern age with the growing of the tall buildings and the architectural design of grades, enables people to lift the increasingly high demands. Now not limited to, the requirements for the elevator ride fast, comfortable, elegant decoration manufacturing firm,, Elevator Safety and reliability and versatility are made increasingly higher demands for this lift is moving control intelligent direction.

In some developed countries in the world of modern intelligent construction, the people have the elevator into the building automation management system important charged device, using advanced electronic monitoring and control instruments, implementation of the operational status of the elevator, maintenance and management of all aspects of security.

In our country, in recent years with advanced control technology of the growing popularity of elevators, especially in the many new intelligent building is the choice of a variety of upscale elevator, elevator control and power control between organic combination possible. But because of the traditional management idea and the elevator manufacturer and weak electricity supplier of their system of relative independence, making our elevator control and power control of mutual penetration of technology and application is slow in most of the high buildings elevator monitoring are basically elevator suppliers provide a closed system, in building security centre is equipped with elevator vendors elevator Monitoring Board for simple display of elevator operation status and can be used with the elevator car to intercom. Elevator and the building automation management system occurred between most of the following three aspects:

(1) elevator from fire Center about signal, elevator in the fire back to the basestation, use the fire ladder with fire.

(2) in the elevator car built-in video camera, video signal (also with audio signals) to the Security Center, monitor show sedan, there's also the elevator floor signal character generator at the same time displayed in the monitor for security personnel in the elevator when committing the fault or bad guys.

(3) Elevator equipped with loudspeakers, can transmit the contents of the public broadcasting system or into the emergency broadcast.

In addition, there are also some important places into the elevator door access part of the regional control, usually in the elevator Hall door or lift is equipped with a card reader, card determines the identity of passengers, to decide whether to run or elevator elevator dock floor. In short, our present in the elevator control and weak current combination of high technology and applications is still at a relatively low level.

II. application of elevator monitoring technology and development direction

Elevator monitoring is the intelligent construction the building automation management system component, the elevator monitoring technology is the building automation management system standard for a basis. Elevator monitoring technology from long-term goals or short-term objective is to design and from the system of single application level two aspects to be taken into account.

First, from system design perspective, the elevator control better long-term objective is to enter the social model of intensive management, at least a regional management model, the advantage is you can each elevator manufacturing, installation and property vendors of products and services of the standard and quality specifications, to various suppliers in an open, fair and equitable conditions of competition, thus improving the quality of their products and services, and makes the overall efficiency greatly improved, costs significantly reduced. Ultimately provide a cheap, safe and comfortable riding the elevator service. To achieve this goal, the Government, or harmonization norms unemployment departments to each vendor's product and service standards and quality.

From our current situation, the lift must be from a technical specification for each elevator supplier provides a unified communication and communication protocols, and technically should not be a problem, and the current main elevator manufacturer is possible even if the computer is not affected by outside interference, you can use a standard protocol for communication to provide lift for running or receive instructions from an external control. According to China's national conditions, and elevator monitoring implementation of the social intensive management go a long way, its main obstacles from two aspects: one is my current property management model is essentially closed small operation, without the elevator monitoring as social intensive management of demand and cries; the second is my existing elevator between various brands has a unified communication protocol, weak monitoring required software and hardware have not been harmonized specifications, many or even the basic configuration. If you want to make social intensive management, improvement of the existing elevators will be significant workload.

So, now on elevator monitoring for the time intensive management of society is not yet mature, but use weak control of high-tech achievement of elevator monitoring is, after all, the future development trend of elevator monitoring regional or social intensive management in our country is also not very far away, to this end, calls on the Government sector and the elevator industry parties, should pay attention to the development direction of elevator monitoring, research, from the standard specification for the design and manufacture, installation, maintenance and so on each link to do some basic work.

Take the elevator car in case of camera-monitor: from the elevator markets of China, the elevator car camera monitoring device in the elevator supplier does not have as a basic configuration of the elevator or optional configurations to consider, so it is usually in the design or manufacturing process is not considered their best recommended scenarios, often based on the temporary additional requirements. The device has a weak electricity supplier in the elevator after installation, the principal Installer during installation, because there is no good solution to standardize the operation of the parties, the effects of unsatisfactory for many, mainly in the following areas:

(1) camera selection not ideal

Elevator car installation of surveillance cameras should be considered and the car's overall coordination and elegant decoration and the hidden, it is advisable to select a roof installation of elevator dome cameras, this camera with a wide-angle lens compact structure, handsome in appearanceAnd concealment. But most of the elevator car installation of ordinary gun camera, the camera directly installed in the cabin top, top of the car, making a hole in the lens exposed. As a result of improper selection of camera, leading to the top of the lift decorated very inconsistent, if the installation doesn't fit hole is even more is needed.

(2) improper camera video cable selection

Elevator monitoring camera video cable should use elevator soft video cable, guarantees that the impedance matching, the television, cable service life is long, and the video cable, power cord, and so video cameras should be done into the accompanying cables, avoiding the elevator runs up bad cables, thereby improving the reliability and service life. Many projects are using ordinary video cable suitable for cable and cable break life shortening, and film and television effects are generally not good. Moreover, no video and radio-frequency cables, of course, this is not acceptable.

All in all, the current firstresponse involving elevator monitoring of communications technology, cabling, security equipment, automation technology, research, specifications, and by borrowing other weak current industry standards, or by the individual to develop standard, elevator to reach unity, enhance individual single elevator monitoring application level, to standardize the elevator control system design. Thereby the further realization of elevator monitoring design become part of the overall design of the elevator, Elevator monitoring design become part of the design of the building automation. In the elevator manufacturing, installation and maintenance also correspondingly increased, implementation specifications, and elevator monitoring device configurations serialized, standardization, then elevator monitoring device will become a unified standard and unified interface of elevator equipment basic configuration items or matching entries, people need to realize the elevator monitoring of regional management and community management is very easy.
