Problems solved by technology

[0003] Due to the wide range of geological disaster prevention and control areas, it is usually necessary to arrange a large number of fracture meters in this area for monitoring. Among such a large number of fracture meters, there will be sampling distortion due to some faults, and the sampled monitoring data does not meet the monitoring requirements. The actual situation of the object will eventually lead to a decrease in monitoring accuracy
However, due to the large number of monitoring points, monitoring equipment (crack meter) and the large amount of uploaded data, it is costly and inefficient to manually check the faulty crack meter, and it is difficult to accurately locate the faulty equipment

Embodiment 1

[0059] Example 1. A kind of troubleshooting method of crack gauge for geological disaster prevention and control, see figure 1 , collect the monitoring data of all crack gauges in the area to be investigated for in-depth analysis, including the following steps:

[0060] a. Set all the crack meter equipment to be checked as a queue to be processed;

[0061] b. Extraction and sorting: select a crack meter object in the queue to be processed, and extract all monitoring data within the preset time period into an independent data table; convert the sampling time of the front-end equipment in the monitoring data into the commonly used The time format is yyyy-MM-dd HH24:mm:ss, and the monitoring data is sorted according to the sampling time;

[0062] c.3σ data cleaning: perform 3σ precision mathematical analysis on the sorted monitoring data, eliminate unreliable data in the monitoring data, and obtain a reliable sampling data set; this step can improve the reliability of the analy...

Abstract

The invention discloses a troubleshooting method of a crack meter for geological disaster prevention and control. After positive and negative waveform queues are obtained by using a 3 sigma criterion precision error analysis method and a linear regression analysis method, waveform changes of the equipment are analyzed by using a T-type signal analysis method, and the waveform dynamic early warning equipment and the stability state of the equipment are judged according to analysis, so that fault equipment is troubleshot. The method has the characteristics of reducing the labor cost, improving the troubleshooting efficiency and being high in accuracy.

Description

technical field [0001] The invention relates to the technical field of troubleshooting of monitoring equipment for prevention and control of geological disasters, in particular to a method for troubleshooting a crack meter for prevention and control of geological disasters. Background technique [0002] With the frequent occurrence of regional geological disasters in recent years, causing huge economic losses, the prevention and early warning of geological disasters has become more and more important. The crack gauge is mainly used to monitor ground fissures in geological disaster prevention and control. However, the current monitoring of ground fissures has the following disadvantages: [0003] Due to the wide range of geological disaster prevention and control areas, it is usually necessary to arrange a large number of fracture meters in this area for monitoring. Among such a large number of fracture meters, there will be sampling distortion due to some faults, and the sa...
