Abstract
The present invention relates to mine safety fields, particularly disclose a kind of mine goaf fire monitoring prior-warning device.It is by wireless transmission without wired connection, the expense for being laid with wired connection is both saved in this way, it will not be restricted because of being wired in layout, additionally it is possible to have better anti-interference (data transmission will not be interrupted because wired connection disconnects) compared with wired connection when Environment of Mine Disaster occurs.On the other hand, underground mine fire sensor monitoring device according to an embodiment of the present invention with wireless transmission function, which only passes through the concentration of carbon monoxide in monitoring coal mine, wind pressure variation and temperature, accurately can forecast and monitor underground mine fire, without monitoring a variety of mine gas and other safety factors, therefore do not have to include more kinds of sensors, the accuracy for thus saving cost, and simplifying software alarm decision method, improving judgement.
Description
Technical field
The present invention relates to mine safety field, in particular to a kind of mine goaf fire monitoring prior-warning device.
Background technique
Coal is the main energy sources substance in China, and China is coal resources country more abundant, coal
Using concerning national economic development, but the exploitation of coal is full of peril, and accident of mine disaster happens occasionally.Fire is in coal mine
One of major casualty, the fire in coal mine are mainly derived from inflammable gas or coal dust burning in mine.With China's coal-mine machine
The raising of tool degree, rubber conveyer fire proportion is on the rise, and sealing-tape machine fire can generate a large amount of cigarettes when occurring
Mist and the pernicious gas that asphyxia can be made one.For the generation of fire preventing, need to be monitored in coal mine to continuous, exogenous fire incubation period
Sign and realize fire forecast, fire expenses for prevention and control can be reduced, avoid disaster accident.
Currently, the main applicable Tube Bundle Monitoring System of the monitoring of China's coal-mine natural fire and forecast, by being deposited in goaf
The forecast of some gas concentrations prevents coal spontaneous combustion, but beam tube technology is only limited to analysis fire gases, to spontaneous combustion temperature,
Ignition region blow down condition etc. is unable to monitor.Meanwhile beam tube equipment is there is also gas conveying distance is remote, sample time delay, point
Analyse that real-time property is poor and beam tube in condensed water accumulate, blocking pipeline is not easy to handle, and it is not accurate enough etc. analysis data occur
Technological deficiency.
Summary of the invention
In order to compensate for the shortcomings of the prior art, the present invention provides one kind can be multi-faceted to the progress of mine goaf fire
The prior-warning device of monitoring.
The present invention is achieved through the following technical solutions:
A kind of mine goaf fire monitoring prior-warning device, characterized in that the oxygen including being set to mine goaf or citadel
Change carbon sensor, wind pressure sensor and temperature sensor, the carbon monoxide transducer acquires carbonomonoxide concentration data in mine,
The wireless wind pressure sensor acquires mine borehole pressure delta data, and radio temperature sensor acquires mine built-in temperature data.
The carbon monoxide transducer, wind pressure sensor, temperature sensor are equipped with wireless network communication module, can be real
Now real-time data receiver and transmission.
The wireless wind pressure sensor includes the pressure sensor for measuring the differential pressure pickup and measurement relative pressure of pressure difference,
The differential pressure pickup is diffusion silicon micro-pressure sensor.
The wireless wind pressure sensor includes the pressure sensor for measuring the differential pressure pickup and measurement relative pressure of pressure difference,
The differential pressure pickup is diffusion silicon micro-pressure sensor.
The beneficial effects of the present invention are:
Fire monitoring prior-warning device in mine goaf according to an embodiment of the present invention can lead to collected mine safety data
Wireless transmission is crossed without wired connection, both saves the expense for being laid with wired connection in this way, it will not be because of being wired at
It is restricted in layout, additionally it is possible to have better anti-interference (will not be because of wired compared with wired connection when Environment of Mine Disaster occurs
Connection disconnects and interrupts data transmission).On the other hand, the underground coal mine according to an embodiment of the present invention with wireless transmission function
Fire sensor monitoring device, which only passes through the concentration of carbon monoxide in monitoring coal mine, wind pressure variation and temperature, accurately to be forecast
With monitoring underground mine fire, without monitoring a variety of mine gas and other safety factors, therefore do not have to include more kinds of biographies
Sensor, thus the accuracy for saving cost, and simplifying software alarm decision method, improving judgement.
Detailed description of the invention
The present invention will be further described below with reference to the drawings:
Fig. 1 is operation schematic diagram of the present invention.

Specific embodiment
Attached drawing is specific embodiments of the present invention.As shown in Figure 1, a kind of mine goaf fire monitoring prior-warning device,
It is characterized in, carbon monoxide transducer 2, wind pressure sensor 3 and temperature sensor 4 including being set to mine goaf or citadel,
Carbonomonoxide concentration data in the carbon monoxide transducer acquisition mine, the wireless wind pressure sensor acquisition mine borehole pressure become
Change data, radio temperature sensor acquires mine built-in temperature data.The carbon monoxide transducer, wind pressure sensor, temperature pass
Sensor is equipped with wireless network communication module 5, is able to achieve real-time data receiver and transmission.The wireless wind pressure sensor 3 wraps
The differential pressure pickup of measurement pressure difference and the pressure sensor of measurement relative pressure are included, the differential pressure pickup is diffusion silicon micro-pressure-difference
Sensor.The radio temperature sensor be set at mine goaf or sealing-tape machine and thermometric it is online be 150 DEG C, the wireless temperature
Spending sensor includes data acquisition module 1 and multiple temp probes 6 connected to it.
In addition to the technical characteristic described in the specification, remaining technical characteristic is technology known to those skilled in the art.
