Abstract
The utility model discloses a novel methane sensor and relates to the technical field of safety detection of coal mines. The novel methane sensor comprises a housing (1), a methane inductor (2), a signal converter (3), a digital display (4), a sound alarm device (5) and a light alarm device (6), wherein the methane inductor (2) and the signal converter (3) are arranged in the housing (1), the digital display (4) is arranged at the front part of the housing (1), the sound alarm device (5) and the light alarm device (6) are arranged at the upper part of the housing (1), the methane inductor (2) is connected with the signal converter (3) through an amplifying circuit, the signal converter (3) is connected with the digital display (4), and the sound alarm device (5) and the light alarm device (6) are connected with an internal circuit in the housing (1). The novel methane sensor can continuously detect the concentration of methane in a production place of the coal mine and ensure safety production.
Description
Technical field:
The utility model relates to mine safety detection technique field, is specifically related to a kind of novel biogas sensor.
Background technology:
In the Coal Production process; Locate to produce methane at getting working face, goaf, return aircourse, dynamo-electric chamber etc., methane concentration exceeds standard and can cause the staff to poison, and serious words can cause the methane blast; Consequence is more serious, threatens staff's personal safety.
The utility model content:
The purpose of the utility model provides a kind of novel biogas sensor, and it can guarantee safety in production in the concentration of Coal Production place continuous detecting methane.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises shell 1, methane inductor 2, signal converter 3, digital indicator 4, voice guard 5, visual alarm 6; Methane inductor 2, signal converter 3 are arranged on the inside of shell 1; Digital indicator 4 is arranged on the front portion of shell 1; Voice guard 5, visual alarm 6 are arranged on the top of shell 1; Methane inductor 2 is connected with signal converter 3 through amplifying circuit, and signal converter 3 is connected with digital indicator 4, and voice guard 5 is connected with shell 1 interior internal circuit with visual alarm 6.
The utlity model has following beneficial effect: it can guarantee safety in production in the concentration of Coal Production place continuous detecting methane.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Referring to Fig. 1, this embodiment adopts following technical scheme: it comprises shell 1, methane inductor 2, signal converter 3, digital indicator 4, voice guard 5, visual alarm 6; Methane inductor 2, signal converter 3 are arranged on the inside of shell 1; Digital indicator 4 is arranged on the front portion of shell 1; Voice guard 5, visual alarm 6 are arranged on the top of shell 1; Methane inductor 2 is connected with signal converter 3 through amplifying circuit, and signal converter 3 is connected with digital indicator 4, and voice guard 5 is connected with shell 1 interior internal circuit with visual alarm 6.
When methane is arranged;, amplify the back through multistage amplifier circuit and produce an output signal the proportional feeble signal of content through the methane inductor, send into A/D conversion input port in the single-chip microcomputer sheet; Convert this analog signals into digital signal through signal converter; Single-chip microcomputer is handled this signal then, and realizes showing functions such as warning.
This embodiment can guarantee safety in production in the concentration of Coal Production place continuous detecting methane.
