In November 2001, China's accession to the world trade organization to make the Chinese economy to the direction of global integration and a big step forward. The Chinese market will be more open, more free trade, that is to say more foreign products will participate in the domestic market competition, and product prices due to tariff reduction will be very competitive. Facing the increasingly severe market environment each enterprise first consider how to survive. To survive, we must improve the competitiveness of enterprises, in the factors that can change the rules of competition, technological change is the most significant one. How to maintain the leading position in the elevator technology so as to keep the competitive advantage of the enterprise? First of all business managers must be aware of the elevator technology development status, and develop a business elevator technology development strategy, in order to enable enterprises not only to survive and can be developed. What is the development trend of elevator technology in the next period of time? (1) environmental protection. In today's world, it is very clear that the relationship between survival and development: no environmental protection can not survive, there is no fundamental to the development of survival. Green concept has been popular in the world, the green concept is the general trend of the development of the elevator. Some experts predict who will be the first to launch green products and to seize the market, who will grasp the initiative in market competition". The main development trends are as follows: continuous improvement of product design, elevator production of environmentally friendly low energy consumption, low noise, no leakage, no, no Water Leakage hoistway guide electromagnetic interference nooil pollution of the. The elevator traction syntheticnylon rope steel belt without lubricating oil pollution traction mode. Elevator decoration will be no environmental pollution materials (less). The regeneration technology of the lift and the full load of the elevator in the elevator. Install the elevator will be installed without scaffolding. Elevator parts in the production and use of the environment has no impact on the environment (such as the brake must not use the leather) and the material can be recycled. (2) drive system using permanent magnet synchronous gearless machine. The traction machine worm gear, permanent magnet synchronous gearless machine and traditional worm transmission has the following advantages: compared to a) permanent magnet synchronous gearless machine is directly driven, no worm gear, worm gear, permanent magnet synchronous motor for asynchronous motor stator coil is required to account for local, and the production of neodymium the main material of iron boron permanent magnet synchronous motor is a high energy density high remanence and high coercive force, the air gap flux density generally reached more than 0.75T, so it can achieve small volume and light weight. B) high transmission efficiency. Due to the use of permanent magnet synchronous motor direct drive (no worm gear and worm gear) its transmission efficiency can be increased by 20% ~ 30%. C) permanent magnet synchronous gearless machine because there is no noise generated by an induction motor in high speed operation of the bearing and absence of worm gear transmission contact that occurs when the noise, so the noise can be reduced by 5 ~ 10dB (A). D) low energy consumption. According to the working principle of permanent magnet synchronous motor (PMSM), it can be known that the excitation is realized by the permanent magnet, which does not need additional excitation current, so the power factor of the motor can reach very high (in theory). The rotor of permanent magnet synchronous motor without current, rotor loss does not exist. General than asynchronous motor is reduced by 45% to 60%. Because of the low efficiency and high energy consumption, the energy consumption is reduced. E) permanent magnet synchronous gearless machine because there is no tooth wear and no lubrication oil changed regularly, so the service life is long, and almost no maintenance. In the near future if we can solve the problem of permanent magnet synchronous motor production cost as soon as possible, the permanent magnet synchronous gearless machine will replace the traction machine composed of worm and worm gear motor. Of course, in the future, the superconducting power drive technology and magnetic levitation drive technology will also be applied in the elevator.

3) elevator industry will be information, network. How to combine the elevator control system with the network technology will be the main trend in the future. Today in twenty-first Century to provide products and services customer satisfaction has become related to the issue of enterprises of vital importance. Elevator access to the Internet to provide customers with better quality throughout the service. Major brand manufacturers in the future in order to survive and development will create its own elevator website in the public network (special lift platform), which is a lift is the only way which must be passed, the Internet to achieve the following functions: a) with the network all lift up supervision, ensure the safe operation of the elevator, ensure the safety of passengers. When the elevator malfunction, lift through the network to the customer service center sends a signal to the maintenance personnel can timely and accurate understanding of the elevator malfunction causes and related information, the customer's personal safety is threatened, and repair to the scene of the accident in the first time, at the same time through the network to the passengers in the elevator comfort, the negative impact the elevator down to the lowest. Can also be through the elevator network within the time required to automatically scan each part of the elevator to find the accident hidden trouble to do prior to repair, reduce the stop time, improve the quality of service enterprises. (b) elevator online trading (lift business website). Now the traditional marketing system is a person to person sales (or face to face sales), due to the need for a large number of sales staff, its high cost of sales. If the network media through the elevator business website, you can greatly reduce the cost of sales. On the Internet you can display the features, functions, shapes and sizes of your products as well as the required dimensions of the building. If you fill in the relevant data of the project on the Internet, it will automatically lift flow calculation, and provide N elevator configuration according to the calculation results (including lift type, load, speed, number of stops, waiting time, running time) scheme for the user to choose. If the user needs can also get all the program offer, you can sign the purchase and sale contract online, through online banking payment, so as to complete the purchase and sale of the contract. Of course, you can download any information on the Internet to be useful for the day after the use of. C) using the network fast, accurate features, reduce production costs. In Chinese after joining WTO, various enterprises (especially joint ventures and foreign-funded enterprises) in order to reduce the cost of global procurement is inevitable, avoid being influenced by various improper means in the procurement process, the use of the elevator site tendering and bidding can ensure purchasing cheap elevator parts, its operation is very low. Can also have fixed all purchased parts factory, supporting the factory through networking manufacturers after receiving the order, the technical department to arrange production schedule and parts production division table through the network quickly and accurately for purchased parts factory, factory production orders issued, and indicate the place of delivery (usually reduced from production the factory to the assembly plant to the site and freight shipped directly to the site), at the same time through the network notification is approved by the manufacturer of professional installation team to install electric (help) ladder. After the installation is complete, the installation team on the Internet to the manufacturers and the relevant government departments to apply for acceptance. In short, from sales to installation and after-sales service, many of the work can be done through the network, and the cost is low, fast, accurate, good quality of service. (4) the application of Bluetooth technology in elevator. Install the elevator let people know that line, on line is very time-consuming and error prone work capacity. If the control panel and the call system are connected via Bluetooth technology, wireless call will be another revolution in the control of the elevator and it will bring us great benefits. A) installation period will be reduced by more than 30%, the direct benefit is to reduce the cost of installation, customers also due to the use of the elevator cycle costs from the order to reduce and improve cash flow. B) using Bluetooth technology in elevator elevator control system will make extensive use of the latest and fastest computer, which will further improve the reliability of the elevator, the failure rate is greatly reduced, the control accuracy is further improved, the result is the elevator more comfortable, more accurate leveling. At the same time it is possible for the future through the network to check the status of the elevator, in particular, prior to the elevator maintenance can do better and more comprehensive, but also to further accelerate the enterprise elevator internet. C) the transformation of the old ladder is more easy, the time required, the cost will be reduced. According to the statistics table will be 50 thousand old ladder to enter the market, the use of the technology will have a huge social benefits and enterprise benefits. Believe that any enterprise will not give up this opportunity. E) is a good solution to the elevator control and peripheral equipment compatibility and contact. In particular, the elevator and escalator can be summarized into the building management system or intelligent management system.

(5) in the elevator to the development of high technology, while we are also clearly aware that China's per capita income is low, particularly sensitive to prices, in this special environment, the market is an urgent need for a simple, reliable universal type of elevator. In the future this type of elevator about the total demand for more than half of China's elevator. The elevator is characterized in that the elevator configuration meets the minimum requirements, but the price is very low, low failure rate, high reliability, durability, basic in its service life without maintenance, and easy to use. This type of elevator technology development direction is: a) high technology and new materials in the production of the application of the elevator parts. Such as the surface of parts and high-tech paint, so that the service life is greatly extended. With low price and high reliability in elevator special electronic universal computer instead of price low reliability to control elevator. Production process improvement of B. Parts process improvements to reduce product prices, while more durable. Production processes and ways to change. Can make this kind of elevator production and modern large-scale automobile production, the use of assembly line production. And the yield is very high, with an annual output of 4 to 50 thousand sets of elevators. C) a large number of standard parts. Almost all parts of this kind of elevator can be purchased in the market standard parts.
