Problems solved by technology

These technical means often transmit a large amount of data, require a dedicated network such as optical fiber, and have high construction costs. Moreover, these technical means only send out alarm information when a fault occurs or after it occurs. At this time, the fault has already occurred. In many cases, there is very little time left for people to rescue, and it is often impossible to prevent the damage in time

Abstract

The invention provides a diagnosis and early-warning system for elevator faults. The diagnosis and early-warning system comprises a sound and vibration signal acquirer and a sound and vibration signal analysis server, wherein the sound and vibration signal acquirer is arranged in an elevator car, connected with the sound and vibration signal analysis server and sends acquired sound signals and / or vibration signals to the sound and vibration signal analysis server; and the sound and vibration signal analysis server processes the sound signals and / or vibration signals. According to the diagnosis and early warning system for elevator faults, hidden faults of an elevator can be discovered as soon as possible, sufficient maintenance time is saved, and heavy losses are avoided. The running safety and reliability of elevators in an area range can be greatly improved once the diagnosis and early warning system is applied to the elevator Internet of Things field.

Description

technical field [0001] The invention relates to the technical field of elevator operation safety monitoring, in particular to the technical field of elevator operation safety monitoring and early warning. Background technique [0002] With the increase of urban high-rise buildings, more and more elevators have been put into operation. While elevators bring convenience to people, elevator failures have also had an impact on people's life safety. In 2007, there were 33 elevator accidents across the country, accounting for 13% of the total number of special equipment safety accidents. Among them, there were 22 elevator fatal accidents, resulting in 25 deaths and 10 serious injuries; 38 elevator accidents occurred in 2008; in 2010, there were records in our country There were more than 44 serious elevator accidents in my country, and 43 people died. [0003] In order to ensure the safe and reliable operation of elevators, various safety measures have been designed and put into ...
