Embodiment 1

[0035] see figure 1, an 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, and photo video; the server end The modules include inspection application, task assignment, inspection report review, and inspection report approval;

[0036] 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, and adopts the fixed IP of th...

Embodiment 2

[0043] On the basis of Embodiment 1, the control module analyzes the collected elevator data information, including the following steps: S1, detecting and analyzing data feature extraction; S2, establishing a database; S3, stratifying the new data set; S4, Obtain new data results; it is convenient to accurately judge the fault information of the elevator, and the inspection is accurate.

[0044] In addition, S1, detection and analysis data feature extraction, first perform data segmentation during original data processing, and then perform feature body extraction for each segment of data, and select time domain, frequency domain and time-frequency domain data features; S2, establish a database According to the speed of elevator operation and the degree of fault, the data characteristic signal is layered, and the clustering algorithm is used to find the cluster center of each layer for each layer, and a small set of fault types is obtained. Classifier training, you can extract ...

Embodiment 3

[0046] The difference from Embodiments 1 and 2 is that the state of the elevator inspection is divided into 3 categories: normal, abnormal, and alarm; all inspection points do not have an elevator system with an alarm index exceeding the alarm threshold value; a certain alarm index exceeds the alarm threshold. The value is abnormal; alarm: when a certain indicator of the system exceeds the alarm threshold, the system can send out an alarm signal, and when the system returns to normal, the alarm signal is released.

[0047] In order to increase the accuracy of the elevator inspection, the alarm threshold calculates the data indicators according to the normal data in each working state when the monitoring and analysis results of the control module are not obtained, and then reports to the police according to the mean value μ and standard deviation σ of these data indicators The threshold y satisfies the following relationship:

[0048] y=β·(2μ+2σ) 1 / 2 ;

[0049] β is the relat...

Abstract

The invention discloses an elevator inspection video auxiliary system, which includes 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 video ;The server module includes inspection application, task assignment, inspection report review, and inspection report approval; the mobile terminal inspection module and the server module realize data interaction through the interface, forming a complete elevator inspection system, improving inspection efficiency and inspection efficiency Accuracy; through the 24-hour monitoring of the elevator by the inspection system combined with the remote monitoring module of the Internet of Things, the safety of the elevator is greatly improved and the safety of people's lives and property is guaranteed.

Description

technical field [0001] The invention belongs to the field of elevator inspection, in particular to an elevator inspection video auxiliary system. 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 echo inside and outs...
