Hangzhou Passenger Elevator Internet of Things Construction
The Internet of Things (IoT) of the elevator refers to the sensor or elevator main controller, which continuously collects the daily operation information of the elevator and transmits it to the remote terminal through the network for real-time monitoring so as to realize the intelligent management of the elevator failure or accident.
A set of data sufficient to prove this network "efficiency." Since the "96,333" operation, it has received over 17,000 emergency telephone calls and saved more than 18,000 calls. The average time it takes for rescue workers to reach the site has dropped from the previous 40 minutes to 14.07 minutes and the on-site rescue shortened to 4.17 minutes.
"Automatic alarm and risk warning, is the application of Internet of things played the greatest role." City Special Equipment Emergency Disposal Center said that there are more than 70,000 elevators in Hangzhou, access to the network there are 3961 elevators, Mainly new district and staff-intensive shopping malls, hotels, hospitals, schools and other places equipped with elevators.
In the future, Hangzhou will further roll out the passenger elevator safety IOT system to "monitor" more elevators. "On the one hand, we require the new passenger elevator to be integrated into the intelligent management, and on the other hand, we are also studying the cooperation with operators to promote the smart reconstruction of existing elevators." The official said that installation of IOT devices has been included in the passenger elevator maintenance unit Rating system, through the assessment of stars, to help users identify more reliable elevator maintenance units, so as to promote the survival of the fittest.
At present, the old elevator network is not large scale, mainly due to the actual installation of equipment, may be subject to its obsolete structure or design and special treatment, the general cost of each passenger elevator are more than million, plus Follow-up maintenance also costs. Therefore, the existing elevator maintenance unit as the main body of responsibility, lack of enthusiasm for related inputs. The owner of the elevator has the right to use, it is difficult to form a clear consensus, requiring maintenance units to access the network.
Most of Passenger Elevator are newly-built residential areas, because the equipment is relatively new, the financial pressure is not great, and some developers use it as a selling point. Others are special public places such as hospitals and schools. Finally there are more than 100 and some In fact, in theory, is also a new elevator, while others are included in the Hangzhou New Deal pilot elevator, the government funds subsidies.
