Noise Control
The elevator is a source of noise; let it be quiet. It is well known that service plants and installations in buildings (including elevator systems) produce airborne and structure-borne sound....
Improved Monte Carlo Method for Apartment Configuration
Program builds on existing elevator-traffic configuration studies to achieve optimal results. by Shi Xiaoliang, Si Liangqun and Wan Jianru The elevator is the indispensable means of vertical transportation in the...
Applied Research on Office Building Elevator Configuration
A case study illustrates that the CMOPSO algorithm method is better than the traditional elevator configuration method of improving the service quality of office buildings. by Ma Lianzhe, Luo Zhiqun,...
A New Method for Measuring Escalator or Moving Walk Overspeed and Anti-Reverse Protection
A testing system that uses an advanced single-chip microcontroller that can produce simulated overspeed and low-speed signals to test escalator or moving-walk protection by Junhua Shen, Yihui Ruan, Rongfeng Lu...
Methods for Evaluating Elevator RTT
Six methods are used to evaluate round-trip time (RTT), using numerical analytics and simulation. by Lutfi Al-Sharif, Ahmad M. Abu Alqumsan and Ahmad T. Hammoudeh The evaluation of the elevator...
Open Communication Protocols for Elevators, Part 2
In the first article of this series (ELEVATOR WORLD, July 2014), the science and concept of open and interoperable protocols were discussed, with an introduction to the seven layers of...
Open Communication Protocols for Elevators, Part 1
Applications in elevator systems for the popular LonTalk standard are discussed. Compatibility, interoperability, interchangeability, and open and standard protocols have been the hottest terminologies in the building-automation industry over the...
Predicting Elevator Traffic Flow Using SAS
The Statistical Analysis System (SAS) software is used, and its results are verified with measured data. by Xu Ruiying, Yao Lianghong, Yu Kun and Wan Jianru High-rise and super-high-rise buildings...
for Tall and Slender Buildings
Virtually all tall buildings are subdivided into zones served by groups of four or six elevators. These groups, with large, single-deck cars, reflect the planning concepts of the attendant-operated elevators...
Grid-Connected Feedback Control
An LCL filter aids the conversion of elevator feedback energy to AC for it to be safely sent back to the grid. by Wang Yanqing, Jiang Qing, Cao Jie and...
