Description
Technical field
The present invention relates to CH_4 detection instrument field more particularly to a kind of methane transducers.
Background technique
Safety of coal mines is always China's concern and urgent problem, and the acquisition production of coal mine is faced with many difficulties,
Especially coal mine can generate a large amount of flammable explosive gas in process of production, and in recent years, safety of coal mines explosion accident frequently occurs,
Huge economic loss and casualties are caused, and causes the pollution of environment, as gas detection sensor moves to
In coal production, Safety of Coal Mine Production has obtained certain change, and methane is the gas of no color or smell, only by sensitive reliable
Detecting instrument just can be carried out detection, and methane transducer can detect the variation of methane concentration, and record and be transferred to alarm,
When reaching certain numerical value, alarm will start warning device, avoid the generation of accident, and the detection methane of existing sensor is dense
Degree variation range is not wide enough, and accuracy and sensitivity is not high.
Summary of the invention
The problem to be solved by the invention is to provide a kind of sensitiveer, accurate, firm methane transducers.
To solve the above problems, the invention adopts the following technical scheme:
A kind of methane transducer, including sensor housing, display screen, alarm lamp, sensor circumscription socket, alarm jingle bell,
Sensor detecting device and sensor internal circuit board, the sensor internal circuit board are embedded in sensor shell body, by
New Type of Chip Microcomputer and highly integrated digital circuit are set up；The display screen, alarm lamp, sensor circumscription socket, alarm are rung
Bell and sensor detecting device are electrically connected with sensor internal circuit board；The sensor detecting device is by high concentration CH_4 detection
Room, low-concentration methane sensing chamber, methane inlet plenum composition.
Further, further include handle, be set to above the sensor housing.
It further, further include sealing rubber ring, the sensor housing includes front housing and rear shell, is embedded within sensor
In the gap of front housing and rear shell.
Further, the alarm lamp group that the alarm lamp is made of High brightness Red LED.
Further, the alarm jingle bell is piezoelectric ceramics.
The dense methane transducer of GJ-40 coal mine height of the present invention has the beneficial effect that the present invention since internal circuit board is adopted
With state-of-the art single-chip microcontroller and highly integrated digital circuit, to have sensitiveer, accurate, firm detection performance.

Specific embodiment
The present invention is further described in detail with reference to the accompanying drawings and detailed description.
Referring to Fig. 1 and Fig. 2, a kind of methane transducer, including sensor housing 1, display screen 4, alarm lamp 12, sensor
Circumscription socket 2, alarm jingle bell 8, sensor detecting device 10 and sensor internal circuit board 9, the sensor internal circuit board
9 are embedded in sensor housing 1, are set up by New Type of Chip Microcomputer and highly integrated digital circuit, fundamentally improve sensor
Accuracy and sensitivity；Display screen 4, alarm lamp 12, sensor circumscription socket 3, alarm jingle bell 8 and the sensor inspection
Device 10 is surveyed to be electrically connected with sensor internal circuit board 9；What the alarm lamp 12 was made of High brightness Red LED
Alarm lamp group；The alarm jingle bell 8 is piezoelectric ceramics；The sensor detecting device 10 by high concentration CH_4 detection room 5,
Low-concentration methane sensing chamber 7, methane inlet plenum 6 form.
Further include handle 3, is set to 1 top of sensor housing, is bolted with shell 1.
Further include sealing rubber ring 11, the sensor housing 1 include front housing and rear shell, be embedded within sensor front housing with
In the gap of rear shell；The sealing rubber ring 11 is dustproof and waterproof sealing rubber ring.
When work, the methane in test environment enters methane inlet plenum 6 with diffusion way and sensing element reacts simultaneously
Generate corresponding with methane concentration electric signal, when being judged as high concentration methane, electric signal through excessive concentrations CH_4 detection room 5,
When being judged as low-concentration methane, electric signal passes through low-concentration methane sensing chamber 7, and then the signal is amplified turns through modulus
It changes, is sent to sensor internal circuit board 9, be sent to after single-chip microcontroller carries out data processing by sensor circumscription socket 2
The downhole monitoring substation and ground central station being attached thereto realize networking monitoring under row, monitoring and number show harmony on the spot
Light alarm.
It should be noted last that the above specific embodiment is only used to illustrate the technical scheme of the present invention and not to limit it,
Although being described the invention in detail referring to preferred embodiment, those skilled in the art should understand that, it can be right
Technical solution of the present invention is modified or replaced equivalently, without departing from the spirit and scope of the technical solution of the present invention,
It is intended to be within the scope of the claims of the invention.
