Problems solved by technology

Post-failure inspection and maintenance refers to the inspection and maintenance after the escalator fails. This is only a relief measure for the fault. Preparing spare parts for maintenance in advance will bring a greater economic burden
Although regular inspection and maintenance can reduce the occurrence of escalator failures to a certain extent, it not only has high maintenance costs, but also many failures are caused by improper regular maintenance.
In addition, these safety inspection methods largely rely on the accuracy of testing instruments and the experience level of inspectors. It is difficult to monitor the operating status of the escalator in real time, and it is impossible to provide timely early warning or alarm for faults based on the operating status of the escalator.
Although there are some methods for monitoring the status of escalators in the technology, for example, by setting Hall speed sensors, laser ranging sensors, etc. to collect the operating conditions of passengers on the escalator and perform automatic diagnosis, and by setting transformers to detect The running state of the escalator, by setting the image acquisition module to collect the image on the escalator, and then performing image recognition to determine whether there is an abnormality, etc., the existing methods of monitoring the escalator are only for the monitoring of the escalator Or the detection and control of some functions is not universal, or it is only for some parameter indicators of escalator operation, the online monitoring status is not comprehensive, or it only has monitoring functions, no early warning and diagnosis functions, etc., and cannot realize automatic monitoring. Comprehensive online detection, fault alarm, fault early warning and remote fault diagnosis of escalators, etc.

Abstract

The invention discloses a system and a method for monitoring state of an escalator. The system comprises a signal sensing sub system, a data acquisition sub system and a monitoring and diagnosing main system, wherein the signal sensing sub system is used for obtaining state information, in an operation process, of the escalator; the data acquisition sub system is used for acquiring and obtaining corresponding original state information after pre-processing the obtained state information, and storing the original state information; and the monitoring and diagnosing main system is used for carrying out online monitoring, early-warning and alarm processing after carrying out analysis and feature extraction on the original state information to obtain a real-time state feature vector, and carrying out self-learning type intelligent diagnosing and fault predicating on the state feature vector by combining with historical fault data and / or expert knowledge base. The system can be used for realizing comprehensive online monitoring of the escalator, can be used for accurately carrying out intelligent diagnosing and fault predicating, and can be widely applied to the monitoring industry of the escalators, moving sidewalks and elevators.

Description

technical field [0001] The present invention relates to the monitoring field of escalators, in particular to an escalator state monitoring system and method, which can be used to monitor steps running along a fixed line or boxes running along rigid guide rails, and electromechanical equipment that lifts or transports people or goods in parallel . Background technique [0002] Escalator, also known as escalator, or automatic pedestrian elevator, escalator, escalator, is a fixed electromechanical device with a cyclic movement ladder path that continuously transports passengers up or down in large quantities. Commonly used in subways, airports, stations, office buildings, shopping malls, docks and other places. like figure 1 As shown in the figure, the escalator consists of a drive system, a ladder system, a handrail system, a metal structure and an electrical control system. The drive system includes a motor, a reducer, a drive chain and a main drive shaft. And comb tooth p...
