Embodiment 1

[0046] Such as figure 1 As shown, a remote elevator inspection video-assisted diagnosis method includes the following steps:

[0047] S1, inspectors log in to the system from the terminal inspection module, and receive inspection tasks from the server after logging in;

[0048] S2. After receiving the inspection task, the inspectors go to the elevator inspection site to conduct inspections and make inspection reports, take photos and videos at the same time, and send the inspection reports and photos and videos back to the server module;

[0049] S3, the operator of the server module reviews and approves the inspection report, and determines the operation status of the elevator with inspection;

[0050] S4, while on-site inspectors are inspecting, remotely monitor the overall operation status of the elevator through the remote monitoring module; generate an inspection report through the control module to clarify the elevator operation failure situation.

[0051] In step S1, ...

Embodiment 2

[0057] see figure 2 , the diagnostic system adopts a remote elevator inspection video auxiliary system, including a mobile terminal inspection module and a server module; the inspection video auxiliary system also includes a remote monitoring module, and the mobile terminal inspection module includes identity authentication, task collection, on-site inspection, Photo and video; the server module includes inspection application, task assignment, inspection report review, and inspection report approval;

[0058] The remote monitoring module includes a data acquisition module, a data transmission module, and a control module; the acquisition module includes a sensor and a front-end machine installed in the elevator car, and the data acquisition module transmits the data information through the transmission module after collecting the data information when the elevator is running. To the control module; the data transmission module supports the network transmission form of GPRS, ...

Embodiment 3

[0065] On the basis of embodiments one and two, the control module analyzes the collected elevator data information, including the following steps: A1, feature extraction of detection and analysis data; A2, establishment of a database; A3, stratification of new data sets; A4, obtain new data results; it is convenient to accurately judge the fault information of the elevator, and the inspection is accurate.

[0066] In addition, A1, detection and analysis data feature extraction, firstly segment the data during the original data processing, and then perform feature body extraction on each piece of data, and select data features such as time domain, frequency domain and time-frequency domain; A2, establish The database, according to the speed of the elevator and the degree of failure, divides the data characteristic signal into layers, and uses a clustering algorithm to find out the cluster center of each layer for each layer, and obtains a small set of fault types. Carry out cl...

Abstract

The invention discloses a video-assisted diagnosis method for remote elevator inspection, which includes the following steps: S1, the inspector logs in the system from the terminal inspection module, and receives the inspection task from the server after logging in; S2, after receiving the inspection task, the inspector goes to Carry out the inspection and make an inspection report on the elevator inspection site, take pictures and videos at the same time, and send the inspection report and photo video back to the server module; S3, the operator of the server module reviews and approves the inspection report, and determines the location of the elevator to be inspected. Operation status; S4, while on-site inspection personnel are inspecting, the overall operation status of the elevator is remotely monitored through the remote monitoring module; the mobile terminal inspection module and the server module realize data interaction through the interface, forming a complete elevator inspection system, improving inspection The efficiency and accuracy of inspection; through the inspection system combined with the remote monitoring module of the Internet of Things, the elevator is monitored 24 hours a day, which greatly improves the safety of the elevator.

Description

technical field [0001] The invention belongs to the field of elevator inspection, in particular to a remote video-assisted diagnosis method for elevator inspection. Background technique [0002] In recent years, cities have developed rapidly, and elevators are an indispensable tool for urban development, which will lead to a sharp increase in the number of elevators. Elevators not only play a huge role in improving the living standards of urban residents, but also due to their own particularity, once an elevator fails, it will cause serious damage to the city. people with significant security implications. [0003] At present, the elevator management level and the elevator operation monitoring level are relatively backward. The elevator monitoring system in the past did not have a relatively perfect management method, the system versatility and compatibility are relatively poor, and the old monitoring system has a low troubleshooting rate; The monitoring is limited to the e...
