Residential elevators is still the mainstream market
According to incomplete statistics, China lifts Association, 2004 annual subscriptions to lift production volume may more than 80,000 Taiwan. 2005, although the pace of growth slowed elevator industry, but also in more than 80,000 Taiwan. Elevator market situation will continue to look good, the new product development and the application of new technologies will promote lift market development. It is estimated that 80,000 Taiwan in the new clothing lifts, residential elevators occupied 70%, which is also China's domestic market in recent years with China's prosperity are closely related. It is one of the characteristics of residential elevators in the use of functions compared with the previous Keti essence no different. It is characteristic of the two services targeting residents did not like the high-grade lift for luxury decoration. Therefore, the price of residential elevators positioning relatively low. Characteristics of the three residential buildings is now my many are a small structure of a residential elevator purchase orders are often not a two, but the purchase of computers, nearly 100 more persons Taiwan. Residential elevators to lift the industry will undoubtedly bring up a good development opportunities. Elevator industry increased investment
As national policy to lift the adjustment has ceased production two years elevator acceptance issuance of work permits and re-started, the end of investment inaccessible elevator industry conditions. Lift investment to the industry last year, the National additional lift production enterprises dozens, hundreds of other related businesses. From the investment point of view the content of most traditional investment enterprises or to lift products, and household staircase and the lift is no room new investment hot spot. Investment analysis of the phenomenon from the elevator, the elevator is the industry's open-door policy for investors enthusiasm. Granted restrictions, not only building technical problems, one important factor is subject to high lift restrictions, and lift not only daily transport tool is the hallmark of human civilization, the technology development is reflected in social progress and civilization.
With computer technology, communications technology and control technology for the development of intelligent buildings a reality, and the wisdom of building the lift is an important means of transport, the technological development has attracted worldwide attention and intelligent level. Intelligent lifts first smart buildings with all automation networking, such as with building control systems, fire safety systems, security surveillance systems in the world linked to a high-efficiency and high-quality lift, safe service tool serial communications in wiring simple, such as the transmission of information advantage in the lift control system applications increasing, The board removed a large number of import and export of computer interface circuits, reducing wells Road, the number of rooms in the wiring, greatly enhancing reliability. With intelligent building improvement, the technology has begun to lift bus system and the building control BAS,FAS,SAS.
Elevator operation from the standpoint of intelligent control to lift quality service quality. Control procedures should adopt advanced management rules for the management group charged with the best send staircase model. The group now has not a single control algorithms to rely on "the shortest waiting time of passengers" as the goal, but a vague theory, neural networks, expert systems approach will be integrated into the factors (that expertise) attract groups control system. In both these factors affect passengers psychological factors, there are also going to happen to be evaluated decision that the current operational status of expert systems and elevators mix together multiple control objectives. Lifts voice announcements and information that can implement thoughtful service. The use of genetic algorithms for passenger traffic patterns and send staircase rules optimization, and since learning of the elevator control rules evolution to adapt to environmental changes. "people-oriented" design of the elevator control system will enable the quality of service is getting better and better lifts.
Lift people out of the lift failure has been plagued by the contractor, in the early 1980s to lift a lift manufacturers increased process monitoring system, installed in the lift Jiaoxiang camera and communications system, the passengers trapped Jiaoxiang surveillance personnel can establish contact with the building. As a result of this facility is limited to lift the building and the security personnel responsible for, once the storm lifts, have informed professionals to solve. Now the RMON service system in the long-range surveillance system is a step that sets advanced communications device, failure diagnosis, integrated microprocessors for its transmission line through the city, elevator operation and the failure of information to remote service centers (RMON lift maintenance center), elevator maintenance personnel to know the problem and how to deal with. If Jiaoxiang door failures were due to the occurrence of a specified level, long-range maintenance center under fault conditions judgement, may allow the use of remote-controlled door sedan chair to open the doors and floors, in the absence of maintenance personnel to the scene of trapped personnel can leave Jiaoxiang. If the failure of maintenance personnel to the scene only to be excluded, for the trapped personnel at the center to immediately broadcast the three Jiaoxiang voice lift tensions. RMON escalator installation, in addition to monitoring performance, monitoring repair center under the suddenly showed a rapid processing of information, so as to prevent injuries. Long-distance services to users benefit is obvious, not only to lift the RMON users receive a components, and allows users to enjoy a set of services. Distance maintenance control center always monitoring of their contract elevator, the lift ready to know the operation and failure attributes, maintenance personnel to failure staircase prior knowledge of the maintenance projects, reduced maintenance costs and service time, which pre-maintenance type of after-sale approach is highly popular abroad users trust, This will also be my lift an important direction for the development of industrial technology.
From the environmental perspective, the "green" concept will become the new mainstream of the 21st century color, a global market for green business development will provide a vast space launch 21 giant green products, and capture the green marketing market will be able to sustain the initiative in the hands of the competition.
Lift the total energy consumption of about building 3%~7% it with the building functional, high floor area and trips. Measures to reduce energy lift is multifaceted. These mainly include : the full use of raw materials and re-use; Choose efficient drive systems, elevators and escalators in the optimal allocation of parameters; Elevator mechanical systems reduce inertia and friction resistance; Re-balance and re-use of reasonable; Entrance layout, trips and freight planning, the selection of energy-efficient lighting, which will need the lift in design optimization options and determine in advance.
The group stops in less staircase layout, a server-driven operation is a two Jiaoxiang separately from the energy conservation programme. Another way is to reduce energy consumption in the course of operating the lift control. Use elevators empty uplink and downlink, full electrical power by the state characteristics of renewable energy will be fed back into the power grid, energy-saving measures such notable effect on the staircase at high speed. Another energy-saving programme will be realized in software control. If a real-time control of traffic patterns and try to lower operating frequency to carry more passengers to lift the stoppings to the minimum. Jiaoxiang elevator calls and registration instructions Ecumenical floors imported passenger elevator control programme is the way a revolutionary technology that enables passengers to the original layer station became clear unknown purpose layer, thereby enabling efficient control system to send staircase highest. Another measure to reduce operating efficiency of the operation is to lift up into a simple mode change speed parameters that elevator control system operational speed, acceleration and acceleration rate curve changes with the operation of both distance changes, but also with Jiaoxiang load changes. Through simulation software simulation, identify the best operation between different floors curve.
Use the elevator machine rooms in the roof edge, making full use of solar energy as an elevator will also be added to the new study. In addition to the lift oil pollution (hydraulic oil, transmission oil, lubricants, etc.) to a minimum, the electromagnetic compatibility of the lift is another issue studied. The elevator is the only building in a large capacity frequent electrical, electromagnetic interference is the main culprit. Elevator electrical and electronic devices produce electromagnetic radiation will affect the building of office equipment, such as radios, television sets, computers, cordless telephone. Also lifts environment should not be affected by electromagnetic radiation. Especially elevator safety circuit isolation measures should be reliable. Currently the EC has developed a magnetic-noising of CE standards, such as wireless environment, in the frequency range between 30MHZ~230MHZ allow the radiation level is 30dB, distance 30m; in 3~10m context is 40dB. In cable transmission environment, the level and frequency of the radiation and currents. If the current is not greater than 25A, for 0.15MHZ~0.50MHZ frequency range between the maximum allowed radiation level is 79dB. I believe that with the lift technology, high-speed and efficient, intelligent, green, the elevator will provide better service to humanity. No gear, no room, electromagnetic compatibility, RMON lift industrial technology will be the major research direction in the next few years
