Abstract
A device for monitoring gas consistency in coal mines comprises a gas sensor, a single-chip, a wrist type LCD and an audio and visual alarm, wherein the output end of the gas sensor is connected with the input end of the single-chip; and the output end of the single-chip is connected with the wrist type LCD and the audio and visual alarm. The device for monitoring gas consistency in the coal mines has the advantages that firstly, the device performs real-time monitoring to gas consistency in working regions of the coal mines via the gas sensor and displays gas consistency via the wrist type LCD at the same time for instantly starting the audio and visual alarm to timely remind staffs in the working regions of the coal mines to rapidly evacuate out of the working regions once the gas consistency reaches or exceeds a preset critical value; and secondly, the device can simplify structure and lower construction cost.
Description
Technical field:
The utility model relates to the safety device that uses on a kind of colliery, the particularly a kind of coal mine gas concentration monitoring device that can monitor, show coal mine gas concentration in real time.
Background technology:
The mine disaster of China in recent years frequently takes place, and causes serious casualties and enormous economic loss.In these mine disasters, be mainly gas explosion, mine caves in and the mine water leak accident.The gas that gathers in the ore bed of down-hole is discharged in mining process in the air in the well gradually, if the deficiency in draught under the mine when reaching finite concentration in the air of gas in well, will set off an explosion in case run into Mars, disaster takes place.For fear of the generation of mine disaster, should update and improve mine production safety monitoring system and mine disaster oneself rescue aid.The gas boring and surveying system has been installed according to the mandatory requirement large tracts of land of country in domestic many collieries at present, though these systems play a good role to the coal mine gas security alarm, but, they are transferred in the computer of the outer management of well department after in use the fire damp concentration data can only being gathered from the down-hole, and are in the size of staff's monitoring in real time zone gas density of down-hole.
Summary of the invention:
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and provides a kind of and can monitor in real time, show the coal mine gas concentration monitoring device of coal mine gas concentration.
As above design, the technical solution of the utility model is: a kind of coal mine gas concentration monitoring device is characterized in that: be made up of firedamp sensor, single-chip microcomputer, wrist formula LCD and audible-visual annunciator; Wherein, the output of firedamp sensor is connected with the input of single-chip microcomputer, and the output of single-chip microcomputer is connected with audible-visual annunciator with wrist formula LCD respectively.
Above-mentioned firedamp sensor adopts MQ5.
Above-mentioned single-chip microcomputer adopts ATMEGA16 (L).
The utility model has the advantages that: 1, this equipment utilization firedamp sensor is monitored the gas density in coal mine working zone in real time, and by wrist formula liquid crystal display displays.When gas density met or exceeded the threshold of setting, this equipment just started sound and light alarm immediately and in time reminds the coal mine working personnel to withdraw the working region.2, simple in structure, construction cost is low.
Description of drawings:
Fig. 1 is a structured flowchart of the present utility model.
The specific embodiment:
As shown in the figure: a kind of coal mine gas concentration monitoring device, form by firedamp sensor MQ5, single chip computer AT MEGA16 (L), wrist formula LCD and audible-visual annunciator; Wherein, the output of firedamp sensor is connected with the input of single-chip microcomputer, and the output of single-chip microcomputer is connected with audible-visual annunciator with wrist formula LCD respectively.
This equipment is set up a kind of gas density monitoring display system based on ATMEGA16 (L) single-chip microcomputer, utilizes firedamp sensor MQ5 to monitor gas density in real time, and by wrist formula liquid crystal display displays gas density.When gas density exceeds standard, send the sound and light alarm signal, remind the coal mine working personnel in time to withdraw the workspace.
