Problems solved by technology

[0003] At present, there are two main problems in the field of domestic elevator safety maintenance: one is that passive maintenance cannot reduce the losses caused by failures, and the other is that the lack of a scientific maintenance decision-making system leads to high maintenance costs and low efficiency of elevators
The elevator system has long lacked fault prediction and maintenance methods based on fault prediction. When faults break out in a concentrated manner and maintenance resource allocation is unreasonable, the fault loss will greatly increase

Embodiment Construction

[0042] The elevator health management and maintenance system based on the Internet of Things and the collection and evaluation method of the present invention will be described in detail below in conjunction with the embodiments and the accompanying drawings.

[0043] The elevator health management and maintenance system and collection and evaluation method based on the Internet of Things in the present invention designs the elevator health management and intelligent maintenance system according to the Internet of Things system architecture, and divides the whole system into three levels: the perception layer, the network layer and the application layer. Various sensors and elevator data collection terminals are installed on the perception layer. The sensors are low-cost, low-power, and multi-functional wireless sensors. Data information fusion, eliminate the original redundant data and convert it into a unified format to send to the remote end; the network layer forwards the r...

Abstract

The invention relates to an elevator health management and maintenance system based on the Internet of things and a collection and assessment method, wherein the elevator health management and maintenance system based on the Internet of things comprises a perception layer, a network layer and an application layer which are sequentially communicated through a network, the perception layer performs communication with the network layer by a VPN (virtual private network) or M2M (machine-to-machine), and the perception layer comprises a plurality of elevator data collection terminals which are respectively correspondingly arranged on a plurality of elevator controllers and have the same structure; the network layer comprises a cloud computing platform, a management center of the Internet of things and a GPRS (general packet radio service), 3G (third generation) and 4G (fourth generation) network management system; and the application layer comprises an elevator mass data processing module, an elevator health assessment module and an elevator intelligent maintenance module which are sequentially connected. The elevator health management and maintenance system disclosed by the invention can support large-scale elevator health monitoring and maintenance, is favorable for reducing the elevator maintenance cost and improving the elevator maintenance efficiency, and can keep minimal maintenance resource demands in reliability, availability and safety.

Description

technical field [0001] The present invention relates to an elevator. In particular, it relates to an elevator health management and maintenance system based on the Internet of Things and a collection and evaluation method. Background technique [0002] Due to the rapid increase in the number of domestic elevators in recent years, the elevator failure rate has risen sharply, and the number of serious elevator accidents has a significant upward trend. It is not only inefficient and low-quality to carry out maintenance only through isolated elevator maintenance companies, but also the entire elevator maintenance industry lacks an elevator safety evaluation standard, and unified safety management measures cannot be implemented. In order to achieve the unification of elevator safety and maintenance standards from both technical and management aspects, improve maintenance efficiency, and improve elevator safety performance, an elevator health management and intelligent maintenanc...
