Embodiment 1

[0018] A method for gas monitoring and early warning, comprising the steps of:

[0019] 1) Obtain multi-point gas concentration data and store it in the database;

[0020] 2) Process the data in the database as a time series to obtain gas concentration time series data, where time is the real-time time when the gas data is collected, and gas concentration is the dependent variable of time;

[0021] 3) Design a depth-restricted Boltzmann machine model, pre-train the collected time and gas concentration data, and obtain the optimal weight matrix and optimal bias value as the initial weight value of the deep convolutional neural network model and the initial value of the offset value; the optimal weight matrix and the optimal offset value are used as the initial weight value and the initial value of the offset value to establish a four-layer deep convolutional neural network model, and use the model to analyze the gas concentration status Monitoring; the four-layer deep convolut...

Abstract

The invention relates to a method for monitoring and early warning of flammable gas concentration, which mainly solves the problem of poor safety in the prior art. The present invention stores the flammable gas concentration data in the database by adopting a flammable gas concentration monitoring and early warning method, and processes the data as a time series to obtain the flammable gas concentration time series data, and then outputs it through a neural network, The concentration boundary value is set in advance, and when the boundary value is reached, the technical solution of automatic alarm by the system solves the above problems well, and can be used in flammable gas concentration monitoring and early warning.

Description

technical field [0001] The invention relates to a method for monitoring and early warning of flammable gas concentration. Background technique [0002] With the continuous development of society and the improvement of the quality of life, human beings put forward higher requirements for their own safety. Harmful gases in dangerous workplaces such as gas stations, coal mines, and chemical plants have been threatening the safety of life, which will directly affect the quality of life. [0003] At present, the underground gas over-limit alarm mainly uses the sound and light alarm device of the methane sensor for sound and light alarm. Because the sound and light alarm device of the methane sensor has a small alarm sound level, the sound signal level is about 80dB(A), and the light signal can only be seen at a distance of 20m. When a gas accident occurs in a certain place underground, only the place near the methane sensor Operators can perceive the alarm information, but thos...
