Embodiment 1）

[0022] The method for identifying the false data of the calibration experiment in the monitoring data of the mine gas sensor in this embodiment is implemented by the monitoring background of the existing coal mine safety monitoring system. Real-time monitoring data, and forming the gas concentration data sequence of the gas sensor; the monitoring background adopts the following steps to automatically identify the false data generated by the calibration experiment in the gas concentration data sequence of the gas sensor:

[0023] ①Use formula (1) to judge whether the increase value between the gas concentration values ​​obtained from two adjacent inspections is greater than the set concentration increase judgment threshold Y1, if not, end this identification; if so, enter step ② ;

[0024] C1-C0>Y1 (1)

[0025] In the formula, C1 is the current gas concentration value, and C0 is the previous gas concentration value adjacent to C1; in this embodiment, the concentration increase...

Abstract

The invention provides a method for identifying calibration experiment pseudo-data in mining gas sensor monitoring data. Gas concentration data sequences are processes by a monitoring background through the following main steps that whether the increased value of two gas concentrations obtained successively is larger than a set threshold value or not is judged through comparison; the tour-inspection time t0 corresponding to the gas concentration value obtained in the previous time is determined, and the gas concentration maximum value and the tour-inspection time t1 obtained when the gas concentration maximum value occurs at the last time are determined within the tour-inspection threshold value range after the tour-inspection time t0; the gas concentration average value within the tour-inspection threshold value range after the t1 is calculated, and the tour-inspection time when it is determined that the gas concentration value is not larger than the average value within the threshold value range is denoted as t2; the difference value of the maximum value and the average value is calculated, and the difference value and the judgment threshold value are compared; and whether the gas concentration sequences between the t0 and t2 are the calibration experiment pseudo-data or not is determined according to set judging conditions. The pseudo-data generated by a gas sensor calibration experiment can be identified automatically and effectively in the gas concentration monitoring data sequences, and the automation level of coal mine safety monitoring is improved.

Description

technical field [0001] The invention relates to the field of gas monitoring data analysis in a coal mine safety monitoring system, in particular to a method for identifying false data generated by a gas sensor calibration experiment in the monitoring data of a mine gas sensor. Background technique [0002] In 2016, the State Administration of Work Safety clearly stated in Article 9 of the "Technical Plan for Upgrading and Transforming Coal Mine Safety Monitoring System" that the application and analysis of monitoring and monitoring data should be strengthened, including false data labeling and abnormal data analysis. [0003] The use of gas sensors to monitor the gas concentration in coal mines, especially underground mines, is an important part of coal mine safety monitoring. The monitoring background in the coal mine safety monitoring system obtains the real-time monitoring data of the gas sensor located at the front end through regular inspection, and automatically proces...
