Embodiment Construction

[0015] Such as figure 1 As shown, there is a gas detection unit 8 in the miner's lamp 5 , the gas detection unit 8 is fixed in the casing 6 of the miner's lamp 5 , and the gas detection unit 8 detects gas gas through the gas sensor 4 .

[0016] The gas sensor 4 in the gas detection unit 8 and the casing 6 have a breathing channel 3 , and a breathing protection mold 7 is arranged outside the breathing channel 3 , and the gas detecting unit 8 is electrically connected to the charging circuit 9 .

[0017] The front side of the housing 6 is a light reflector 2, and an LED light 1 is inserted in the light reflector 2. The LED light 1 is controlled to be in a power-saving or non-power-saving state by buttons, and power-saving is for some LEDs to work. Non-power-saving is all LED lights work.

[0018] Such as figure 2 As shown, the gas detection unit 8 includes a single-chip microcomputer 801. The single-chip microcomputer 801 is electrically connected to the gas sensor 4 through ...

Abstract

The present invention relates to a gas detector, specifically to a wireless communication type gas detector, which is characterized in that a gas detection unit comprises a microcontroller unit, wherein the microcontroller unit is electrically connected with a gas sensor through a filtering amplification electric circuit, and is electrically connected with a wireless transmission receiving circuit, a gas sensor signal passes through the filtering amplification electric circuit, and is input into an input end of the microcontroller unit with an A / D converter, the gas detection unit is electrically connected with a charge battery through a power supply management electric circuit, and a charge electric circuit is electrically connected with the power supply management electric circuit. According to the present invention, a breathing channel exists between the gas sensor and the outer housing, and a breathing protection film is arranged outside the breathing channel, such that detection of gas by the gas sensor can not be affected, and the gas sensor can be protected from inhaling powder pollutants, wherein the gas sensor can not normally work if the gas sensor inhales the powder pollutant.

Description

technical field [0001] The invention relates to a gas detector, in particular to a wireless communication type gas detector. Background technique [0002] In the case of rapid growth of coal production, it also brings frequent serious accidents in coal mines. During the "Tenth Five-Year Plan" period, a total of 1,398 major accidents occurred in coal mines across the country with 3-9 deaths, an average of 280 cases per year, accounting for 11% of the number of major accidents in the country; 214 serious accidents with 10-29 deaths occurred , with an average of 43 accidents per year, accounting for 36% of all kinds of serious accidents in the country; 42 particularly serious accidents that killed more than 30 people at one time, with an average of 8 accidents per year, accounting for 58% of all kinds of particularly serious accidents in the country. There is a big gap between my country's coal enterprises and the world's major coal mining countries in terms of production safe...
