Description
Technical field
The present invention relates to mine automatic spraying device for reducing dust sensor.
Background technology
Mine spray dust-fall device sensor is applicable to underground coal mine detection or induction: whether blast mining face blows out, conveyor, scrapper conveyor whether convey materials, whether whether unloading point unloads coal, whether milling coal hole produces coal, have pedestrian or locomotive to pass through, the various working parameters such as coal mining machine in full-mechanized mining face run location.In its normal work period, when running into personnel by spraying point, the water circuit system of spray outfit must be closed in time, after personnel pass through, then open the water circuit system of spray outfit.In prior art, mine spray dust-fall device working sensor model comparision is single, can not realize long-term safety reliability service.
Summary of the invention
The object of the present invention is to provide a kind of mine automatic spraying device for reducing dust sensor, its mode of operation variation, can long-term safety reliability service.
For achieving the above object, technical scheme of the present invention is a kind of mine automatic spraying device for reducing dust sensor of design, be provided with pyroelectric infrared inductive mode, touch-control detection mode, acoustic control detection mode, infrared emitting pattern and infrared receiver pattern, by inner toggle switch selection mode, a sensor can only select a kind of mode of operation simultaneously.
Preferably, described pyroelectric infrared inductive mode is specially: distance of reaction >=5m, induction angle 30 °.
Preferably, described touch-control detection mode is specially: impact energy >=1.0J.
Preferably, described acoustic control detection mode is specially: sound level intensities >=115dB (A).
Preferably, described infrared emitting pattern and infrared receiver pattern are specially: launching and receiving distance >=5m, angle 30 °.
Advantage of the present invention and beneficial effect are: provide a kind of mine automatic spraying device for reducing dust sensor, and its mode of operation variation, can long-term safety reliability service.
The operating principle of mine automatic spraying device for reducing dust sensor of the present invention:
When selecting pyroelectric infrared inductive mode, out-of-date when there being people to walk before the lens of sensor, the infrared rays that human body sends constantly alternately enters in " highly sensitive district " from " blind area ", the human body infrared signal received so just is made to input with dynamic impulse form, this pulse signal is converted to the signal of telecommunication by sensor, then amplifies after process through sensor internal circuit and deliver to single-chip microcomputer and carry out calculation process; When the signal of telecommunication reaches alarming value, single-chip microcomputer sends alarm signal by output circuit.
When selecting touch-control detection mode, when there being the touch-control spring of object of which movement impact microphone, clash into when the impact energy produced reaches alarming value and converted to the signal of telecommunication by sensor, after the single-chip microcomputer of sensor internal carries out calculation process, send alarm signal by output circuit.
When selecting acoustic control detection mode, when sensor receives acoustic signals, this acoustic signals is converted to the signal of telecommunication by sensor, then amplifies after process through internal circuit and deliver to single-chip microcomputer and carry out calculation process; When the signal of telecommunication reaches alarming value, single-chip microcomputer sends alarm signal by output circuit.
When selecting infrared emitting pattern, code signal is converted to by infrared transmitting tube and carries code infrared signal (optical signal) by the single-chip microcomputer in sensor.
When selecting infrared receiver pattern, when having object or person from selecting between the sensor of infrared ray transmitting function and this sensor through out-of-date, infrared receiving terminal in this sensor does not receive the infrared signal being loaded with code signal, and single-chip microcomputer sends alarm signal by output circuit.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
The technical scheme that the present invention specifically implements is:
Mine automatic spraying device for reducing dust sensor, be provided with pyroelectric infrared inductive mode, touch-control detection mode, acoustic control detection mode, infrared emitting pattern and infrared receiver pattern, by inner toggle switch selection mode, a sensor can only select a kind of mode of operation simultaneously.
The operating principle of mine automatic spraying device for reducing dust sensor of the present invention, as shown in Figure 1:
When selecting pyroelectric infrared inductive mode, out-of-date when there being people to walk before the lens of sensor, the infrared rays that human body sends constantly alternately enters in " highly sensitive district " from " blind area ", the human body infrared signal received so just is made to input with dynamic impulse form, this pulse signal is converted to the signal of telecommunication by sensor, then amplifies after process through sensor internal circuit and deliver to single-chip microcomputer and carry out calculation process; When the signal of telecommunication reaches alarming value, single-chip microcomputer sends alarm signal by output circuit.
When selecting touch-control detection mode, when there being the touch-control spring of object of which movement impact microphone, clash into when the impact energy produced reaches alarming value and converted to the signal of telecommunication by sensor, after the single-chip microcomputer of sensor internal carries out calculation process, send alarm signal by output circuit.
When selecting acoustic control detection mode, when sensor receives acoustic signals, this acoustic signals is converted to the signal of telecommunication by sensor, then amplifies after process through internal circuit and deliver to single-chip microcomputer and carry out calculation process; When the signal of telecommunication reaches alarming value, single-chip microcomputer sends alarm signal by output circuit.
When selecting infrared emitting pattern, code signal is converted to by infrared transmitting tube and carries code infrared signal (optical signal) by the single-chip microcomputer in sensor.
When selecting infrared receiver pattern, when having object or person from selecting between the sensor of infrared ray transmitting function and this sensor through out-of-date, infrared receiving terminal in this sensor does not receive the infrared signal being loaded with code signal, and single-chip microcomputer sends alarm signal by output circuit.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
