Hitachi Elevator (China) recently unveiled in Kunming its the next-generation smart elevator MCA-ES, which uses advanced intelligent control technology to monitor users’ riding experience. The new model is designed for 5G and is running on an open platform.
According to data from Qianzhan Industry Research Institute, China’s smart building market will reach 640 billion yuan by 2020.
With a focus on the development of smart buildings, Hitachi Elevator in recent years has been committed to building Internet of Things solutions, while leveraging its own experience in smart cities and smart buildings to promote the development of smart buildings.
According to the company, the MCA-ES model can achieve a higher level of speed and position control because it has a tolerance in the elevator’s vertical position when stationary of +/-0.1 mm. This ensures the elevator’s high accuracy landing on each floor despite building shrinkage, settlement and climate change, among other factors. This also vastly reduces the likelihood of a passenger tripping and falling when the elevator does not line up perfectly with the ground of the floor it has stopped.
“Statistics show that safety is the leading concern for 90% of elevator passengers,” said Liang Dongming, chief engineer at Hitachi Elevator.
He added that for safety issues that have raised most concerns, the MCA-ES model has obtained the safety integrity level (SIL) 3 certification and features a more comprehensive functional and good big data processing capability.
The new elevator model is equipped with a remote monitoring device that collects elevator operation data 24 hours a day. Through AI pre-diagnosis, the big data centre can analyse more than 600 sets of elevator-related data to facilitate preventive maintenance before a failure occurs.
“We have been working with the Nanjing Municipal Government to promote the on-demand service pilot project. Using the AI pre-diagnosis service, elevator abnormalities have decreased by 65%,” said Liang.
