Coal-mine gas movement detection data processing method of mine Internet of Things

Abstract

The invention discloses a coal-mine gas movement detection data processing method of mine Internet of Things, relating to the technical field of coal-mine gas movement detection data processing. The coal-mine gas movement detection data processing method comprises the following steps: installing a wireless access point composed of a sensor preprocessing unit and a sensor judging unit near each fixed gas detector; after simply processing and judging data detected by the fixed gas detectors and data detected by mobile gas detectors around the wireless access points by the wireless access points, uploading the data to a ground workstation through an underground switch, a coal mine Internet of Things transmission platform and a ground switch, grouping the gas detected by the mobile gas detectors and the data detected by the fixed gas detectors into two kinds of data of multi-dimensional gas data points and gas detection data pairs by the ground workstation, carrying out global judgment by respectively adopting a clustering-based adaptive weighting data fusion algorithm and a single-sensor and multi-measurement period credibility fusion algorithm, and issuing a global judgment result to each wireless access point in a broadcasting form. The reliability of the detected data is improved.

Description

technical field [0001] The invention relates to the technical field of mine gas mobile detection data processing, in particular to a coal mine gas mobile detection data processing method of the Internet of Things in mines, which is mainly applicable to the identification and processing of mine gas detection data under multi-data. Background technique [0002] Coal mine safety monitoring system refers to the detection and control of coal mine gas, wind speed, carbon monoxide, smoke, temperature and other environmental parameters and the working status of electromechanical equipment in mine production, transportation, lifting, drainage and other links, and uses computer analysis and processing to obtain data. A system in which gas detection is the most important function of the coal mine safety detection system. There are many safety detection systems commonly used in my country, such as: KJ2, KJ4, KJ8, KJ10, KJ13, KJ19, KJ38, KJ66, KJ75, KJ80, KJ90, KJ95, KJ2000, etc. The cu...

Problems solved by technology

The above-mentioned requirements and regulations are impossible to realize for the mobile point, for example: the mobile point cannot meet the requirements of the gas sensor installation site; when the mobile detection sensor is required to be calibrated with calibration gas every 10 days, thousands of The adjustment of the mobile detection sensor will bring a surge in workload; it is impossible to directly realize the power-off lock at the mobile detection point; in addition, the mobile point measurement is a kind of flow detection, and the detected data has the variability of time and place. The detection data of time and space changes is also not in the original fixed security monitoring system, etc.
