Abstract

Provided is a miner safety helmet alarm instrument which comprises a safety helmet. A power supply module, a gas sensor, a carbon monoxide sensor, and a temperature sensor are disposed in the safety helmet. The gas sensor, the carbon monoxide sensor, and the temperature sensor are connected with an analog-to-digital conversion circuit. The analog-to-digital conversion circuit is connected with a single chip microcomputer. The single chip microcomputer is connected with a nixie display, a photoelectric alarm, and a buzzer alarm. The miner safety helmet alarm instrument has characteristics of portableness, high measuring precision, reliable operation, and an acousto-optic alarm prompt function, and is capable of monitoring parameter indexes in a mining operating plane in real time.

Description

Miner's safety helmet alarm
Technical field
The utility model relates to a kind of mine safety warning device, specifically, relates to a kind of miner's safety helmet alarm.
Background technology
The most dangerous factor of coal mine operation is Gas Outburst, and other monitoring parameters also have CO concentration, borehole operation temperature, wind speed etc.Because existing fixedly supervising device can only be measured a certain position, down-hole, along with pushing ahead of the scope of operation, just there is variation in monitoring environment, exist volume large, detect the not accurate enough shortcoming of data, because on-the-spot fixed instrument has layout underaction, can not reflect the shortcoming of the toxic and harmful concentration of all positions in mine comprehensively.Particularly cannot find in time that leak in general crack and workplace leaks.
Utility model content
For above-mentioned deficiency of the prior art, the utility model provides a kind of easy to carry, miner's safety helmet alarm that measuring accuracy is high.
Technical solution adopted in the utility model is:
An alarm, comprises safety helmet, is provided with power module, firedamp sensor, carbon monoxide transducer and temperature sensor in described safety helmet; Described firedamp sensor, carbon monoxide transducer and temperature sensor are connected with analog to digital conversion circuit respectively, and analog to digital conversion circuit is connected with single-chip microcomputer; Single-chip microcomputer is connected with nixie display, photoelectric alarm and buzzer siren.
Described photoelectric alarm and buzzer siren are arranged on the front sealing of safety helmet in explosion-resistant enclosure, and it is outside that described firedamp sensor, carbon monoxide transducer and temperature sensor are fixed on safety helmet explosion-proof shell.
The beneficial effect of the relative prior art of the utility model:
The utility model miner's safety helmet alarm, easy to carry, measuring accuracy is high, reliable, there is sound and light alarm prompt facility, the parameter index in can Real-Time Monitoring digging operation face.

Embodiment
Referring to drawings and Examples, the utility model is described in detail:
An alarm, comprises safety helmet, is provided with power module 6, firedamp sensor 7, carbon monoxide transducer 8 and temperature sensor 9 in described safety helmet; Described firedamp sensor 7, carbon monoxide transducer 8 and temperature sensor 9 are connected with analog to digital conversion circuit 1 respectively, and analog to digital conversion circuit 1 is connected with single-chip microcomputer 5; Single-chip microcomputer 5 is connected with nixie display 4, photoelectric alarm 3 and buzzer siren 2.
The front sealing that described photoelectric alarm 3 and buzzer siren 2 are arranged on safety helmet is in explosion-resistant enclosure, and it is outside that described firedamp sensor 7, carbon monoxide transducer 8 and temperature sensor 9 are fixed on safety helmet explosion-proof shell.
The utility model is a kind of multi-functional, integrated form miner's safety helmet alarm, is arranged on safety helmet the powered battery of carrying with workman.
Hardware circuit mainly comprises firedamp sensor circuit, infrared CO sensor circuit, temperature sensor, A/D analog to digital converter, power module, single-chip microcomputer, sound light alarming circuit, digital display circuit.Totally 5 of digital demonstrations, wherein temperature shows with the 4th, 5, and gas and the demonstration of CO concentration are with the 2nd, 3, and most significant digit is used for distinguishing gas and CO, shows that 0 does not show any number for gas density, is CO concentration.
Safety helmet and warning circuit unit are become one, realize the function such as Real-Time Monitoring, alarming value setting, photoelectric alarm, buzzing warning of fire damp, CO and temperature.Sensor assembly gathers respectively mine gas, CO and temperature signal, and signal becomes digital signal after sending ADC change-over circuit; The signal of all collections is processed and shows current concentration, temperature value through STC89C52 single-chip microcomputer; By measuring concentration, compare with the alarm threshold value data of setting in advance, if exceed the limit value of regulation, warning system produces photoelectric alarm, buzzing is reported to the police, and prompting miner takes care, and withdraws in time.
The utility model miner's safety helmet alarm, easy to carry, measuring accuracy is high, reliable, there is sound and light alarm prompt facility, the parameter index in can Real-Time Monitoring digging operation face.
