Traction Machine Absolute UpgradeA new generation of environment-friendly high-performance permanent magnet synchronous (PM) traction machine. High quality rare earth permanent magnet materials and high-precision permanent magnet positioning technology are adopted. At the same time, the motor technologies such as sectional punching and riveting integrated core and automatic centralized winding are comprehensively applied. It not only makes the output of the traction machine more efficient, low energy consumption, quiet and stable. Moreover, the axial distance of the traction machine is shorter and the structure is more compact: the new technology of large-sized brake disc and low-noise disc brake is adopted. When outputting safe and sufficient braking torque. Greatly reduce the band brake noise. It is more safe, reliable and durable.
All-digit Intelligence Power System
It utilizes all-digit control intelligent DC-DC power as the substitution for three-phase power transformer to provide power for elevator control system. New power system is not only more stable and reliable, invulnerable to grid fluctuation, but also consume less energy, with higher efficiency and more comprehensive protection.
Mute Brake Control TechnologyCompared to traditional open-loop voltage control, more accurate closed-loop current control mode is now employed to control the action speed and braking forque at all stages of the brake. This has remarkably reduced the noise from the brake during action and improved the comfort of the passengers while taking the elevators.
The Latest Generation of High-power ModuleTake the lead in employing the sixth generation of high-power module system in the industry. Multiple fast protection circuit can better protect the power module, further improving the reliability of the drive system. Meanwhile, the drive control circuit of power module connects with the power module by direct plugging, further enhancing the system's anti-jamming ability.
High-performance and Intelligent CPU Control SystemApply new generation of high-performance CPU technology and PCB system architecture and realize elevator's main control system with multi-chip architecture of motor drive, elevator control management, elevator communication and FPGA logic control. Cooperation work of multiple CPUs has greatly improved the elevator system performance. The redundancy protection with multiple CPUs and the FPGA hardware monitoring have improved system stability and security.
AC VVVF Speed Regulation Control Technology, Full Digital Control TechnologyAdhering to the philosophy of steadily and slowing releasing of profound knowledge and constantly using latest technologies and components in VVVF drive of elevators enable Shanghai Mitsubishi VVVF speed regulation technology to develop rapidly toward high performance, high reliability, digitization and miniaturization. Employing space vector pulse width modulation (SVPWM) technology to realize elevator speed regulation, taking the lead in adopting international latest sixth generation of high-power module, 32-bit high speed digital signal controller (DSC) and large scale integrated circuit and other advanced electrical components,enabling the elevator to accurately regulate the motor rpm completely according to optimum speed variation curve and operate following the perfect speed curved optimized according to modern ergonomics principle. These have realized full digital control and motor drive in true sense and enabled the elevator run smoothly, safely and efficiently.
Data Network Control TechnologyData network control technology based on CANBUS (Field bus) features high communication rate, large data volume. Independent microprocessors are used separately in elevator car command controller, floor indicators inside the car, door machine controller, each landing button and floor indicators and various subsystems. The communication between the various subsystems needs only a few signal lines. This has greatly improved system reliability, electromagnetic interference immunity and flexibility, and reduced the maintenance costs.
Energy Feedback Technology（Optional）Highly energy-saving energy feedback technology based on dual-PWM control can feed the renewable green electric energy, which was consumed through energy consumption resistors, back to the grid without pollution. This can save more than 30% energy compared to common VVVF elevators on average, and so to meet relevant national power quality standards.
LEHY-Ill adopts really small machine room design with the machine room size equal to shaft. This saves machine room space, improves building utilization rate, allows more free building design, and compared to traditional machine room, provides more convenient and safe maintenance of the traction machine, control cabinet, over speed governor and other components.
ITS-21, ITS-2100 group control systems use a high-performance CPU processor for computing and achieving high-speed processing of complex algorithms. High-speed data network has effectively improved the system throughput and scalability. Expert system, fuzzy logic technology and neuron technologies are adopted. Dispatching plan can be given in an intelligent way according to different traffic conditions. This can substantially reduce passengers' waiting time and riding time and reduce elevator operation energy consumption throughout the building by reducing invalid elevator operation.
Multi-beam Safety Edge (MBS) (Standard)Safety edge with multi-beam. Provide double protection by multi-beam and safety edge. During door closing, when a passenger or object is detected. the doors will open again.
Extended Door-open Button (DKO-TB) (Standard)By pressing this button, you can keep the elevator door open for a longer time to facilitate the access of passengers within the hospital.
Voice Announce Device (AAN-S)(Optional)In case of car overload, control operation during disaster or misuse, etc., the speech unit will remind the passengers by broadcasting about how to deal with the emergency, so that to mitigate and eliminate passengers' confusion and anxiety.
False Call Cancelling - Manual (FCC-P)(Optional) If the wrong car button is pressed, it can be canceled by quickly pressing the same button again twice.
Car Arrival Chime (AECC)(Optional)4-5 seconds prior to the arrival of elevator at the call floor. the car arrival chime will prompt the passenger that the car is about to arrive at the destination floor.
Elevator car video surveillance feature (ITV)(Optional)By placing cameras inside the car, you can monitor the status of car from control room, thereby suppressing crime, as well as playing certain role in early detection of the accident.
