Abstract
The utility model relates to an impact-resistant gas sensor for coal mines, which has significant importance in preventing accidents and guaranteeing safety production in coal mines. Gas is one of the important detection parameters in automatic detection to harmful gas under the coal mines. The impact-resistant gas sensor comprises a housing (2) with a hanger (1), wherein a sensor (3) connected with a monitoring part is arranged at the lower end of the housing; a display window, a remote controller receiving window (4) and an indicating lamp (5) are arranged on the housing; a buzzer (6) is mounted in the housing; a power supply connecting interface (7) is arranged on one side of the housing; and an integral circuit with a central controller is mounted in the housing. The impact-resistant gas sensor provided by the utility model is used in various large, middle, small-sized and local coal mines.
Description
Technical field:
The utility model relates to a kind of firedamp sensor, is specifically related to a kind of mining shock resistance firedamp sensor.
Background technology:
Trouble-saving generation and guarantee that Safety of Coal Mine Production has crucial meaning; During the harmful gas robotization detected under coal mine, gas was one of important detected parameters.
Summary of the invention:
The purpose of this utility model provides a kind of ability that the anti-high concentration of sensor is impacted that strengthened, behind the use certain hour, and can automatic sensor to zero point, sensitivity correction.
Above-mentioned purpose realizes by following technical scheme:
A kind of mining shock resistance firedamp sensor, its composition comprises: the housing that has hanger, described housing lower end connects the sensor of monitoring part, have the display window of having, telepilot receiver window and pilot lamp on the described housing, in the described housing hummer is housed, described housing one side has the power supply connector, and the integrated circuit of band central controller is housed in the described housing.
Described mining shock resistance firedamp sensor, described integrated circuit comprises test section circuit, central processing unit partial circuit and segment signal output circuit, the analog electrical signal that acquisition testing is partly got passes through described central processing unit joint detection sensor and the analog amplify circuit partly that the laggard line data of A/D converting digitalization is handled, described sensor is a catalytic combustion method gas sensor, and described catalytic combustion method gas sensor connects zeroing circuit and described analog amplify circuit; Segment signal output is made up of display circuit and output circuit, and connection signalling alarm equipment, described signalling alarm equipment comprises sound and light alarm infrared receiver, prompting alarm, radiator valve, described radiator valve connects described sensor and described analog amplify circuit, and described catalytic combustion method gas sensor connects zeroing circuit and analog amplify circuit.
Beneficial effect:
1. the utility model is at the problem that exists in the mine gas monitoring, new technologies such as integrated use electronics science, control theory, pattern-recognition, estimation theory adopt high-performance catalytic combustion gas sensitive element device, intrinsically safe circuit, infrared remote control adjustment technology and single chip microcontroller technical design.
The utility model adopts linear Constant Temperature Detection bridge circuit design, strengthened the ability that the anti-high concentration of sensor is impacted, after using certain hour, can be automatically to zero point, sensitivity correction, this automatic trimming process user need not intervene does not influence normal use, and zero point drift is eliminated, and can not need suppressed zero for a long time, make sensitivity obtain bigger correction, effectively improved the stability of sensor.
The utility model is used for getting working face under the coal mine, return aircoursies etc. have in the gas explosion gaseous environment, can carry out continuous detecting to gas density, have good repeatability and stability, detection sensitivity is high, measurement range is wide, compatible strong, realized exempting to uncap the infrared remote control adjustment, long service life, easy to operate.
When the numerical value of the utility model monitoring reaches the alarming value of setting, can send the sound and light alarm signal automatically.

Embodiment:
Embodiment 1:
A kind of mining shock resistance firedamp sensor, its composition comprises: the housing 2 that has hanger 1, described housing 2 lower ends connect sensor 3, described housing 2 have display window, with telepilot receiver window 4, pilot lamp 5, in the described housing 2 hummer 6 is housed, described housing 2 one sides have power supply connector 7, in the described housing integrated circuit are housed.
Embodiment 2:
Principle of work:
KGJ-01 shock resistance firedamp sensor is divided into three parts: test section, central processing unit part and segment signal output.The test section is made up of high-performance catalytic combustion gas sensitive element device and analog amplify circuit, and it is responsible for the collection site data, and the data that collect is become the electric signal of simulation; The partly responsible analog electrical signal digitizing that acquisition testing is partly got of central processing unit, i.e. data processing work such as linearization process, digital filtering, zero point drift calibration, sensitivity calibration are carried out in A/D conversion then; Segment signal output is made up of display circuit and output circuit, the result that central processing unit is obtained passes through the display circuit video data, send the methane concentration signal by output circuit, and the back output alarm signal is judged in analysis of data collected, send sound and light alarm after the driving.
Installation method:
In mine, select the comparatively firm end face or the position, a place of side, then a hook is fixed on the position of selection, again sensor is suspended on the hook, notice during suspension that catalysis element will hang down.
