Green technology of energy saving and sustainable future adoption of new structure permanent magnet synchronous motor drive gearless machine, improve system efficiency, while reducing energy consumption; Dual PWM control based on energy feedback technology, while reducing pollution and energy consumption, leading Green Future. ? People-oriented unprecedented comfort using advanced artificial intelligence technology, so take reflects the unprecedented precision and comfort; optional deluxe decoration parts, offers a variety of new materials to choose from, but also for customers tailored systems. 5 big breakthrough? Hoisting machine new upgraded new generation of green high-performance permanent magnet synchronous (PM) traction machine with a high-quality rare earth permanent magnetic materials and permanent magnets with high precision positioning technology, and integrated application of one sub-type punch riveting Automated centralized core and windings and other motor technology, not only the output of the hoisting machine is more efficient, low energy consumption, quiet and smooth, and the hoisting machine axial distance is shorter, more compact; new brake disc with a large size and Low noise disc brake technology, ample safety when braking torque output, dramatically reducing brake noise and have a more secure and reliable, and durable characteristics. ? All-digital intelligent power control system uses intelligent digital DC-DC power supply technologies, alternative three-phase power transformer provides power to the elevator control system. The new power system is not only more reliable, less susceptible to power fluctuations, and lower loss, higher efficiency, more comprehensive protection. ? Quiet brake control technology compared to traditional open-loop control voltage, now using a more accurate current closed-loop control, precise control of each stage holding brake control movement speed and brake torque, significantly reduced when the brake is action noise, improved ride comfort elevator. ? The latest generation of high-power module is the industry's first application of the sixth generation of high-power module system. Fast multiple protection circuit module can be better protected power to further improve the reliability of the drive system. Meanwhile, the drive power control circuit module is connected directly to the power module, further enhancing the anti-jamming capability. ? High-performance CPU and intelligent control system performance CPU technology and the printing plate system architecture a whole new generation, driven by a motor, elevator control management, multi-chip communication architecture and FPGA logic elevator control system to achieve the main elevator. Multi-CPU work greatly improves the elevator system performance, multi-CPU and FPGA hardware redundancy protection monitoring to enhance the system stability and security, six innovative, reliable and comfortable -? AC variable voltage variable frequency speed control technology, all-digital Accumulate control technology uphold the idea, to keep the latest technology and devices used to lift VVVF drive, the Shanghai Mitsubishi VVVF speed control technology towards high performance, high reliability, rapid development, digitization and miniaturization direction. Application of space vector control technology (SVPWM) to achieve lift speed, the sixth generation of the first to adopt the latest international high-power modules, 32 high-speed digital signal controller (DSC) and LSI and other advanced electrical components, so that the lift in full accordance with the best velocity curves to precisely adjust the motor speed, running along the ideal speed curve in accordance with modern ergonomically optimized design made to achieve a fully digital control and motor drive in the true sense, so the elevator running smoothly, safely and efficiently. ? Green energy - energy feedback technology (optional) Dual PWM-based high-energy energy feedback control technology, originally resistor energy consumed by renewable green energy, pollution back to the grid, with an average of 30% energy saving than ordinary VVVF elevator the above. Fully meet the relevant national power quality standards. ? High-speed network - data network control technology is based on CANBUS (fieldbus) data network control technology, high communication efficiency, the amount of data and independent microprocessors were used in the elevator car command controller, car inner floor instructions , door controller, each layer station buttons and floor indicators and other subsystems. The communication between the various subsystems of just a few signal lines can greatly improve the reliability, electromagnetic interference and flexibility of the system, reducing maintenance costs. ??????? Efficient group control - intelligent group control system (optional) ITS-21, ITS-2100 group control system uses a high-performance CPU processor operation to achieve high-speed processing of complex algorithms. High-speed data network, effectively improve the throughput and scalability of the system. Application of expert system based on fuzzy logic, neural element technique. According to different traffic conditions, intelligently presented dispatching plan to substantially reduce passenger waiting time and riding time, and by reducing the ineffective running elevators, elevators reduce energy consumption of the building. ? Innovation Operation - whereabouts Forecasting System (optional) through the efficient movement of forecasting systems, greatly improve the utilization of the elevator and reduce the average waiting time for passengers. When pressed own landing passengers wishing to travel to the floor button, the system will inform passengers of the whereabouts of forecasting designated elevator ride, passengers can go before the designated elevator waiting. When the elevator arrived, no passengers in the car and then press the button to go to the floor, the elevator will be automatically registered and sent to the destination layer passengers. ? High adaptability - really small room design LEHY-Ⅲ using the same size room and hoistway really small room design, shortly saves floor space, improve the utilization of the building, so that architectural design more freedom compared with conventional elevator machine room maintenance traction machine, control cabinet, the governor and other components are more convenient and safer. ? Up to 17 kinds of rich decoration of the car roof, within nine kinds of car control box, 19 kinds of landing equipment display and buttons for customers to choose the type of decoration richer, more beautiful appearance, better meet individual customers needs. Also available in 9 different styles of holistic solutions for customers to choose the car decoration, highlighting contemporary and technological sense of the elevator, the overall effect of the construction and decoration of grace.
