Chongqing Fuji elevator technology new contribution:

　　The company through the introduction of Japan's Fuji technology and developed continuously, absorption and progress, leading to keep pace with the development of modern science and technology, among the world advanced technology to the forefront of elevator, as customers continue to provide better products and better service elevator. The core technology of the company has: Fuji microcomputer control technology and Fuji VVVF VVVF technology, Fuji low-voltage electrical control technology, PFGA high density programmable technology, network control technology, gearless permanent magnet synchronous technology, anti electromagnetic interference, energy feedback technology etc..

Chongqing Fuji elevator features:

　　The company inherited the Fuji elevator "heavy industry" design concept, through the integration of the core technology, making Chongqing Fuji elevator has the following characteristics:

　　Safe and reliable:With perfect safety protection device, since the generation of energy consumption brake, effectively prevent the danger of sliding car; light fault lift can also reach the nearest layer to open the door to put people after the stop ladder. Perfect security protection to ensure the safety and reliability of the elevator operation.

　　Ride comfort:The permanent magnet synchronous gearless traction machine, excellent performance of inverter control technology, noise and vibration damping arrangement structure reasonable, make the elevator running curve to achieve the best condition, small vibration. Ultra low speed synchronous motor mechanical vibration, minimum complete elimination of gear and motor noise, VVVF frequency drive to ensure that no peak current, so that the elevator running smoothly, riding more comfortable.

　　Modern aesthetic feeling:Signal system button modeling, dot matrix color, dynamic dot matrix, so that the elevator quite modern aesthetic.

　　Energy saving and environmental protection:Permanent magnet synchronous motor with high efficiency, the energy consumption is only about 60% of the traditional traction machine, can save the cost of the year.

　　Flexible and compact:Light weight, small size AC gearless traction machine and its weight is only half of the traditional traction machine, compact size reduces the elevator machine room space, the construction cost savings at the same time, provide designers more free space.

Chongqing Fuji elevator control system features:

　　Network:The electronic components distribution in various parts of the elevator for the specific parts of the specially designed, so that the "human - machine" information exchange more convenient, more rich content, the maximum to meet the personalized needs of customers. All parts are connected with the electronic control part of serial communication, the elevator control is very simple, more reliable, the single elevator core network through computer group management are connected by serial communication mode, constitute a set of elevator control network, according to the operating condition, the passengers in the elevator group call request, evaluate passengers psychological waiting time, calculate the optimal dispatch service plan, minimize the waiting time, and improve the running efficiency of elevator and energy saving; through the public network, the operational status of the elevator remote transmission to the elevator management center, a remote elevator management network. Is the equivalent of a "computer housekeeper" for each elevator ".

　　Intelligence:System to control the parameters of the object and elevator parameters to learn, in order to obtain the most ideal running comfort and running efficiency, while ensuring the best level of accuracy. System for fault diagnosis, to ensure the safety of the elevator. Each layer of the station computer has a self closing function in the fault, so that the other layer on the network is not affected. To monitor the operation of the elevator car's load weight, car and layer station button at any time, and make the appropriate treatment if abnormal. The door machine controls the computer to open the door width, the load size and so on the parameter self - learning, will study the result to be processed automatically, in order to achieve the most safe pattern and the best gate operation effect. Pre load start, so that the elevator start more stable.

CF series high speed elevator:

　　For the new high speed ladder type, mainly for the high level of the real estate market and high-grade office market research and development of new products, running speed of 5 m/s, up to 220 meters high. In the control system, the introduction of dual 32 bit microprocessor as the control core, so that the system control accuracy, get a smooth ride comfort. Using advanced analog speed operation to control the frequency converter, the elevator does not need to crawl, direct call, to improve the efficiency of the elevator operation. The speed limiting device is additionally provided with an encoder, which can feedback the absolute position of the car in real time, and a speed monitoring device is arranged in the well path to monitor the running speed of the elevator, and greatly improve the safety of the elevator. Using permanent magnet synchronous motor as power source, no reduction box, no excitation current, high efficiency, energy saving, low noise, maintenance free. Using VVVF frequency conversion speed regulating door machine, the switch door is more stable, lower noise, open and close the use of photoelectric induction type protection device. The elevator energy feedback device will convert mechanical energy into electrical energy, power grid, which can reduce the room temperature and improve the braking torque, and energy efficiency up to 35%, can control 8 sets of elevator, fast scheduling for rapid response operation call, elevator use efficiency.
