New Building Energy-Saving Technology — "Energy-Saving Intelligent Traction Passenger Elevator (Model TKJ-E1050/2.0)" Project Passes Evaluation for Scientific and Technological Achievements in the Construction Industry
The “Energy-Saving Intelligent Traction Passenger Elevator (Model TKJ-E1050/2.0)” developed by Shenlong Elevator Co., Ltd. passed the scientific and technological achievement evaluation organized by the Center of Science and Technology and Industrialization Development of the Ministry of Housing and Urban-Rural Development on May 20, 2022.
Brief Technical Introduction:
The Energy-Saving Intelligent Traction Passenger Elevator (Model TKJ-E1050/2.0) adopts an energy-saving traction machine (Model GTM175-105J-1E), intelligent control system (Model SLEC7000-W), energy-saving door operator control system (Model SL21C) and highly integrated electronic transformer. While achieving energy-saving operation, it integrates an abnormal behavior detection system, smart elevator management system and cloud management system to meet the demands of intelligent elevator management.
The energy-saving traction machine (Model GTM175-105J-1E) of the elevator has a rated power of 14.2 kW, rated speed of 235 r/min, torque up to 575 N·m, efficiency of 92.56% and Class 1 energy efficiency rating. The highly integrated electronic transformer supplies power for the brake of the elevator traction machine and elevator communication, providing two isolated DC voltage outputs with significantly lower energy consumption than inductive transformers. The energy-saving door operator control system (Model SL21C) adopts intelligent dynamic optimization generation technology for motion curves and features high-precision vector servo control. When no command is received, the door system and light curtain system automatically enter the energy-saving mode to reduce standby energy consumption. The car leveling fall prevention device is interlocked with the door operator, which can effectively prevent accidental falling of the car at the leveling position.
The intelligent control system (Model SLEC7000-W) adopts dual 32-bit processors with open-loop / closed-loop vector control modes. It can flexibly adjust the leveling position and realize intelligent management including remote elevator monitoring, user management and group control dispatching. The in-car abnormal behavior detection system (Model SSL435-DB) can intelligently detect certain abnormal behaviors of passengers and dangerous behaviors such as electric vehicles entering the car, and send timely alarm prompts to improve elevator operation safety. The wireless communication technology for smart elevators provides data transmission support for remotely monitoring real-time and historical elevator operation data, automatic fault diagnosis and prediction, and proactive maintenance reminders, improving the convenience of elevator maintenance management. In addition, the elevator is equipped with voice call, mobile APP call, contactless button call, as well as ultraviolet and negative ion sterilization and disinfection functions, helping improve the elevator hygiene and epidemic prevention capacity.
Expert Review:
Adopting technologies such as the energy-saving traction drive host and SLEC7000-W intelligent control system, the elevator realizes intelligent and networked control and contactless call, with stable overall operation and low energy consumption.
The elevator has the following innovations: (1) Self-developed energy-saving traction machine (Model GTM175-105J-1E) with Class 1 energy efficiency; (2) Adoption of highly integrated electronic transformer technology, delivering remarkable energy-saving effect compared with traditional inductive transformers; (3) Energy-saving intelligent door operator control system (Model SL21C) with high-precision vector servo control function; (4) SSL435-DB in-car abnormal behavior detection system capable of alarming for certain passenger abnormal behaviors and electric vehicle entry into the elevator car.
