Embodiment Construction

[0013] Such as figure 1 As shown, there is a gas detection unit 8 inside the miner's lamp 5 , the gas detection unit 8 is fixed in the housing 6 of the miner's lamp 5 , and the gas detection unit 8 detects gas through the gas sensor 4 .

[0014] The gas sensor 4 in the gas detection unit 8 and the casing 6 have a breathing channel 3 , and a respiratory protective film 7 is outside the breathing channel 3 , and the gas detecting unit 8 is electrically connected to the charging circuit 9 .

[0015] 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.

[0016] 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 the am...

Abstract

The invention relates to a gas detector, in particular to a wireless communication type gas detection device. The wireless communication type gas detection device is characterized in that a gas detection unit comprises a single chip microcomputer, the single chip microcomputer is electrically connected to a gas sensor through an amplifying and filtering circuit and is electrically connected with awireless transmitting and receiving circuit, signal of the gas sensor passes through the amplifying and filtering circuit and then is input into the input end of the single chip microcomputer with anA/D converter, the gas detection unit is electrically connected to a rechargeable battery through a power management circuit, and the rechargeable battery is electrically connected to the power management circuit. According to the gas detection device, the gas sensor and an outer shell are provided with a breathing channel, a breathing protection film is arranged outside the breathing channel, sothat the wireless communication type gas detection device cannot be affected to detect gas, and meanwhile, the phenomenon that normal work of the gas sensor is influenced due to the fact that the gassensor sucks dust can be avoided.

Description

technical field [0001] The present application relates to a gas detector, in particular to a wireless communication gas detection device. 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, there were 1398 major accidents with 3-9 deaths in coal mines across the country, 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...
