Elevator vibration signal detection system based on GPRS (general packet radio service)

Abstract

The invention relates to an elevator vibration signal detection system based on GPRS (general packet radio service). The provided detection system is used for remotely acquiring vibration signals, analyzing the signals and calculating corresponding vibration values for the convenience of judging the working quality of an elevator and reducing the fault probability of the elevator. The invention adopts the technical scheme as follows: the system comprises a lift car vibration signal acquisition and wireless data sending device, a wireless data receiving and GPRS remote data transmitter and a remote data receiving and analyzing service center, wherein the lift car vibration signal acquisition and wireless data sending device is mounted on a lift car; the data of the vibration signals acquired by a pair of wireless data transmission modules is transmitted to the wireless data receiving and GPRS remote data transmitter, and a GPRS module on the wireless data receiving and GPRS remote data transmitter is used for transmitting the data to the remote data receiving and analyzing service center through a GPRS network.

Description

technical field [0001] The invention relates to an elevator vibration signal detection system, in particular to a GPRS-based elevator vibration signal detection system. Background technique [0002] According to the 2013 global and Chinese elevator industry research report: under the background of the downturn in the European elevator industry and the slow recovery of the American elevator market, China’s elevator output in 2012 was 529,000 units, a year-on-year increase of 17.56%. The growth rate slowed down, but the output still ranked first in the world. First. Therefore, the expansion of multinational elevator companies in China has accelerated. Under the circumstance that the growth rate of elevator production and sales is slowing down and the number of elevators is increasing, the prospect of China's elevator aftermarket is optimistic. [0003] Statistics from the China Elevator Industry Association show that as of 2012, the number of elevators in China has exceeded ...

AI Technical Summary

Problems solved by technology

This has caused the following problems: the staff engaged in elevator maintenance are uneven, and the prediction of elevator failure is not very accurate; although some large enterprises have their own special maintenance personnel, the sales area of ​​these companies is relatively wide , it is difficult for technicians to regularly maintain the elevators installed by the company

[0008] The hardware part of these elevator vibration signal detection systems is not very portable, and the cost is relatively high, which requires high professional quality of maintenance staff; professional maintenance personnel need to carry these instruments to the site for measurement, so they do not have Solve the problem that elevators are widely distributed and it is difficult for ordinary elevator maintenance staff to adapt
