ELEVATOR INTERNET OF THINGS

Introduction to Internet of Things

 

Under the support of aviation technology and big data, AVIC Elevator independently developed the elevator Internet of Things public service platform. The elevator Internet of Things big data platform of the company uses the big data industry of Guizhou Province to develop elevator after-sales service (elevator maintenance, old ladder transformation, old building retrofitting new ladder, advertising business and other service markets) to provide customers with better after-sales maintenance services. Its working principle is to integrate and transmit the elevator's real-time operating status, video surveillance, fault alarm and other event information to the information management platform through the wired or wireless connection such as 2G/3G/4G and WiFi, using the elevator's original or additional information acquisition device. The management platform processes and analyzes the above data. To realize the elevator remote monitoring, automatic fault alarm, rapid rescue of trapped people, daily management and maintenance, hidden danger analysis and prevention and many other functions.

 

 

The application of the Internet of Things platform has the following advantages:

 

 

(1) Enhance the management capacity of regulatory departments. The integration of elevator operation big data and monitoring data enables the regulatory authorities to directly understand the current operating status, failure rate, rescue of trapped people, maintenance quality and other conditions of the elevator in the jurisdiction, master first-hand information, avoid various artificial or technical distortions caused by layer upon layer of information transmission, and provide comprehensive and accurate big data support for the formulation of regulatory measures.

(2) Elevator rescue is more convenient and rapid, can be remote assistance, elevator technical experts can in the office, by obtaining the integrated controller function code, terminal status and remote modification of part of the elevator function code to assist field engineers to complete debugging and fault handling; Second, it can be remote diagnosis, and on-site personnel have vague descriptions of faults. Through remote diagnosis, maintenance management can be quickly located at the fault point, and the performance of on-site maintenance personnel can be managed through maintenance check-in and maintenance process records to improve work efficiency.

(3) Improve the quality of elevator maintenance. At present, the daily maintenance testing that needs to be carried out on site, on the one hand, is to obtain data at any time through the Internet of Things mobile terminal equipment, which greatly improves the efficiency and quality of daily maintenance; On the other hand, due to low-price competition in the industry, lax internal management of maintenance units or insufficient technical capacity of maintenance, the actual arrival rate of daily maintenance is still short. However, the use of the Internet of Things technology can read the unchangeable original maintenance operation record in the elevator control system through the elevator built-in information acquisition device, and it can determine whether a maintenance is carried out according to the technical specifications and on time.

(4) Achieve safety early warning and improve the quality of elevator products. By analyzing the elevator fault data, operating status parameters and monitoring information collected and summarized by the Internet of Things, the company can continuously improve product design, improve product quality and improve safety performance; At the same time, it can also predict the elevator failure through big data analysis, and carry out targeted maintenance or replace parts in advance. By taking the initiative to improve the safety of the elevator, achieve "on-demand maintenance", truly change the elevator supervision and maintenance "post-repair" into "pre-management", and eliminate possible accidents in the pending state.

(5) Fault reminder, automatic SMS reminder when the elevator fails, can improve rapid response ability, reduce passenger complaints, improve customer satisfaction and reputation.
