The infrared methane sensor is connected to a front-arranged amplifier which is connected with an analog-digital converter which is connected to the single chip microcomputer which is connected with an infrared remote control device. The single chip microcomputer is also connected with a sound-light alarming output system. By adopting the structure, on one hand, mining production is led to be safer by means of sound-light alarming and outage output, and on the other hand, parameters of an alarming value, an outage value and the like can be set in remote mode through the infrared remote control device.
Description
Technical field
The utility model relates to a kind of gas warning system, particularly a kind of mining methane warning device.
Background technology
Safety of coal mines is China's problem demanding prompt solution all the time, and Coal Production faces many difficulties, and is low like mechanization degree, the safety device imperfection, and technical level is low etc., and these all are the hidden danger of safety of coal mines.Can there be flammable explosive gas in the colliery in the safety in production process, these gases are main threats of Coal Production.In recent years, the explosion of coal mines accident frequently takes place, and when having caused huge economy and personal casualty loss, has also caused the pollution of environment.Along with gas detection sensor applies in the Coal Production, Safety of Coal Mine Production has obtained change to a certain extent.
Methane is the gas of colorless and odorless, can only just can detect through sensitive reliable detection instrument.Methane transducer can be reported to the police when methane concentration transfinites automatically.But existing methane warning device can not be regulated sensor and each parameter at a distance, the alarm output facet do perfect inadequately, be difficult to guarantee the safety in production in colliery.
Summary of the invention
It is a kind of safe and reliable that the utility model technical issues that need to address provide, and the mine methane alarming apparatus of desired parameters can long-rangely be set.
For solving the problems of the technologies described above; The mining methane warning device of the utility model comprises power supply, infrared methane sensor, oscillator, single-chip microcomputer and light-emitting diode display; Infrared methane sensor connects preamplifier; Preamplifier connects analog-digital converter, and analog-digital converter is connected to single-chip microcomputer; Said single-chip microcomputer is connected with infrared remote-control device, and said single-chip microcomputer also is connected with the sound and light alarm output system.
Said mining methane warning device has an infrared remote-control device, and it comprises:
Convert various key commands to IR remote controller that serial infrared light code signal sends;
Be connected on the single-chip microcomputer, the serial infrared light code signal that above-mentioned IR remote controller is sent converts the receiver of remote-control sytem that serial electric signal send single-chip microcomputer to handle to.
Said sound and light alarm output system comprises:
The methane concentration value that single-chip microcomputer is obtained converts correspondent frequency into, then the frequency output module of output;
When methane concentration reached alarming value, the output signal produced the audible and visible alarm module that acousto-optic replaces alarm signal;
When methane concentration reaches power-down value, output low level, the outage output module of generation power-off signal.
After adopting above-mentioned structure, on the one hand through sound and light alarm and outage output, can be so that mine production be more safe; Can pass through infrared remote-control device on the other hand, the long-range parameters such as alarming value, power-down value that are provided with.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the theory structure sketch map of the mining methane warning device of the utility model.
The specific embodiment
