Problems solved by technology

Usually when the gas detection system has an early warning, the gas concentration in the environment where the sensor is located is already in a dangerous state. Therefore, the current gas detection system cannot give an early warning before the gas concentration reaches a dangerous state, which affects the timeliness of the early warning.

Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0024] The basic idea of ​​the embodiment of the present invention is: by monitoring the change speed of the concentration of the target gas, it is judged whether the change of the gas concentration is abnormal, and when the change of the concentration of the target gas is abnormal, an early warning is issued.

[0025] see figure 1 , which shows the flow of a gas detection and early warning method provided by an embodiment of the present invention, the method may include:

[0026] S101: The early warning device acquires N concentration change rates of the target gas within the preset first time period, where N is a positive integer greater than 0;

[0027] Exemplarily, the early warning device acquires N concentration change rates of the target gas within a preset first time ...

Abstract

The invention discloses a gas detection early-warning method, device and system. The method comprises acquiring N concentration change speeds of target gas in a preset first time period through the gas detection early-warning device, wherein N is a positive integer greater than 0, and when the gas detection early-warning device determines target gas concentration change anomaly according to the N concentration change speeds and a preset concentration change speed threshold value, producing an early-warning massage through the gas detection early-warning device.

Description

technical field [0001] The invention relates to the field of gas detection, in particular to a method, device and system for gas detection and early warning. Background technique [0002] In coal mines, chemical plants, laboratories and other production or experimental sites with flammable and explosive gases or toxic and harmful gases, gas detection systems are generally installed, such as gas detection systems in coal mines. The current gas detection system generally adopts the method of setting a threshold to monitor the gas concentration for early warning, that is, the gas detection system uses the gas concentration reported by the sensor to exceed the preset threshold as the early warning condition. When the gas concentration exceeds the threshold, the gas detection system performs early warning. Usually when the gas detection system has an early warning, the gas concentration in the environment where the sensor is located is already in a dangerous state. Therefore, the...
