Abstract
The utility model relates to the field of gas alarm in underground coal mining, in particular to a three-color-lamplight voice gas alarm which is characterized by comprises a controller, a gas sensor and a three-color light-emitting diode (LED) lamp, wherein the controller is respectively connected with the gas sensor and the three-color LED lamp, and an output end of a power source of a miner lamp is respectively connected with the controller and the gas sensor. The controller comprises a microprocessor chip, a voice chip, a driving module and a loudspeaker, wherein an output end of the microprocessor chip is respectively connected with the voice chip and the driving module which is connected with the loudspeaker. Compared with the prior art, the three-color-lamplight voice gas alarm has the advantages of: being capable of being carried by undermine operation staff so as to reflect gas concentration of the surrounding environment at any time and effectively reduce the danger caused by gas explosion; adopting lights with three colors, being capable of respectively and obviously alarming safe, dangerous and clinical states, and being capable of giving out alarm voice when dangerous condition occurs by means of the voice chip; and being light in weight and low in power consumption.
Description
Technical field
The utility model relates to the gas alarming field in the underground coal mine mining operations, relates in particular to a kind of three colour lamp light voice gas alarm.
Background technology
The underground mining in colliery accounts for 60% of world's Coal Production, and in coal mine five big disasters, the gas disaster is to cause the disaster of particularly serious dead and wounded accident the most easily, and gas explosion is disaster form the most serious in the gas disaster.
There is the shortcoming of arranging underaction, can not reflect the methane gas concentration of all positions in the mine comprehensively in on-the-spot at present fixed gas alarm, can't find in time that particularly leak in general crack and work plane leaks; The gas leakage detector is the additional of existing fixed monitoring system in the mine; Use also commonplace, but the deficiency that exists is must be through the flow-type detection of security staff and field worker, could the symptom of a trend of discovery accident at any time; In time prevent dangerous generation, device carries inconvenience; And all there is the shortcoming that can't observably warn to underground operators at any time in above-mentioned two kinds of warning devices.
Summary of the invention
The purpose of the utility model provides a kind of three colour lamp light voice gas alarm; Overcome the deficiency of prior art, be worn on the safety helmet, the detection at any time gas density by the underground work personnel; Different according to gas density; Utilize the various colors of tri coloured lantern conversion to send the light caution, send audio alert simultaneously, the generation of gas disaster accident when avoiding underground work.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
A kind of three colour lamp light voice gas alarm comprises controller, firedamp sensor and three-color LED light, and controller links to each other with three-color LED light with firedamp sensor respectively, and the output of head lamp power supply is connected with firedamp sensor with controller respectively.
Said controller comprises little process chip, speech chip, driver module and loudspeaker, and the output of little process chip links to each other with driver module with speech chip respectively, and driver module links to each other with loudspeaker.
Compared with prior art, the beneficial effect of the utility model is:
1) carries by underground operators, can reflect the surrounding environment gas density at any time, reduced the harm that gas explosion brings effectively.
2) light of three kinds of colors of employing can be made eye-catching caution to safety, danger, critical condition respectively, and speech chip can also send chimes of doom to dangerous situation.
3) volume is little, and is in light weight, easy to carry; Utilize the power supply of head lamp power supply, simple in structure, low in energy consumption.

Fig. 2 is the utility model application site sketch map.
Among the figure: 1-safety helmet 2-head lamp power supply 3-head lamp 4-gas alarm
The specific embodiment
Be described further below in conjunction with the specific embodiment of accompanying drawing the utility model:
See Fig. 1, Fig. 2; It is a kind of three colour lamp light voice of the utility model gas alarm example structure schematic block diagram; Comprise controller, firedamp sensor and three-color LED light; Controller is gone into end with two ends of firedamp sensor and three-color LED light respectively and is linked to each other, and the output of head lamp power supply is connected with firedamp sensor with controller respectively, links to each other with the positive pole of head lamp power supply behind the public pole series resistor R of three-color LED light.
Controller comprises little process chip, speech chip, driver module and loudspeaker, and the output of little process chip links to each other with driver module with speech chip respectively, and driver module links to each other with loudspeaker.
When in a single day gas density reaches the gas density that constitutes danger around the operating personnel in the mine; Little process chip MCU of controller puts low level to the P1.1 port, makes the bright ruddiness that sends of LED1, and this moment, gas alarm 4 demonstrations were dangerous here; Gas leakage is arranged; Speech chip conducting simultaneously, loudspeaker sends chimes of doom, and at this moment underground operators must be withdrawn immediately.
When gas density is between safety value and dangerous values around the underground operators in the mine; Little process chip MCU of controller puts low level simultaneously to P1.1 and P1.0 port; Make LED1 and LED2 simultaneously bright, be shown as orange light this moment, this moment, gas alarm 4 was in alarm condition.
The operation occasion under the mine of being suitable for the utility model detects and reports to the police; And will detect data and control speech chip and three-color LED light through controller; At any time reflect staff's gas density on every side, send caution, utilize the power supply of head lamp power supply simultaneously; Real-time detection can be realized, power supply needn't be added in addition.
