Analyzing method and analyzing system of gas accident reason

The invention discloses an analyzing method and an analyzing system of a gas accident reason. The system mainly comprises an information acquisition module, an analyzing and processing module, an alarming reason database and an information output module, wherein the information acquisition module is arranged in a coal mine used for acquiring concentration data of the gas in an area, and converting the concentration data into sensor data to be sent to the analyzing and processing module; the analyzing and processing module is used for analyzing the sensor data, so as to obtain gas concentration values corresponding to the sensor data and corresponding analysis result; the alarming reason database is use for judging whether an alarming standard is reached or not, if so, the alarming information is sent, and the alarming reason database is used for storing alarming standard data; and the information output module is used for displaying the analyzing result output by the analyzing and processing module. With the adoption of the analyzing method and the analyzing system of the gas accident reason, the sensor data in alarming can be acquired at real time through rapid analysis, the alarming position is accurately positioned, and the alarming reason and corresponding handling measures can be given, so that the coal mine safety is improved.
