Problems solved by technology

[0002] In coal mine production, it is often necessary to use a detonator to detonate the detonator. If there are personnel who have not evacuated from the explosion site during the detonation process, there will be a greater safety hazard; It has the function of methane gas detection. If the content of methane gas in the explosion area exceeds the standard, it will lead to the occurrence of gas explosion accidents.

Abstract

The invention provides a methane locking alarm which can effectively detect methane concentration and personnel information in a firing area. The methane locking alarm comprises a microcontroller which has operation and treatment actions and is characterized in that an input port of the microcontroller is connected with a methane sensor and a human body sensor, an output port of the microcontroller is connected with an LED digital display, and a control port of the microcontroller is connected with a recording and playing chip; the recording and playing chip is connected with an audible and visual alarm via an audio power amplifier. The methane closing alarm is provided with the methane sensor and the human body sensor, so that the detonation of a detonating cap under the condition that working personnel do not evacuate or the concentration of methane gas exceeds standard; the recording and playing chip and the audible and visual alarm are also arranged, the double stimulation of audible signals and visual signals are adopted to warn the working personnel in a burst area.

Description

technical field [0001] The invention relates to a methane blocking alarm, in particular to a methane blocking alarm which can effectively detect the methane concentration and personnel information in the blasting area. Background technique [0002] In coal mine production, it is often necessary to use a detonator to detonate the detonator. If there are personnel who have not evacuated from the explosion site during the detonation process, there will be a greater safety hazard; It has the function of methane gas detection. If the content of methane gas in the explosion area exceeds the standard, it will lead to the occurrence of gas explosion accidents. In order to ensure safe production, before the detonator is used to detonate the detonator, whether there are workers on site and the methane gas content on site should be detected. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned technical problems, the present invention provi...
