The invention provides a gas detection alarm device which comprises acquisition devices. The acquisition devices are arranged in an underground environment and are used for acquiring various environmental parameters in real time, and output ends of the acquisition devices are connected with input ends of a microprocessor by wires; output ends of the microprocessor are respectively connected with an alarm device and a power switch used for controlling underground power supply circuits; a relay router is interactively connected with the microprocessor, and underground information is wirelessly transmitted to an upper computer of a ground monitoring center by the relay router. The gas detection alarm device has the advantages that serious accidents of gas combustion and explosion can be fundamentally greatly reduced owing to the audible and visual alarm actions of the alarm device and the power-off action of the power switch; the information is wirelessly transmitted via the relay router, so that an underground condition can be effectively known and controlled via the upper computer of the ground control center.
Description
Technical field
The present invention relates to the safety monitoring system under coal mine, specifically a kind of gas-warning device.
Background technology
At coal mine operation, owing to being subject to the impact of geological conditions, environment and toxic and harmful, various accident of mine disaster occur again and again, and life and property have been caused to serious destructiveness.In poisonous and hazardous gas, the harmfulness of gas is maximum, and gas is the hydrocarbon gas being stored in coal seam, and Main Ingredients and Appearance is methane, is inflammable and explosive gas, and Safety of Coal Mine Production is had to great threat.
Gas is blasted or burnt three conditions, and the one, its concentration, in air, gas density reaches 5%～16%; The 2nd, environment temperature; The 3rd, in sufficient oxygen atmosphere, when oxygen concentration is greater than 12%, will blast, burn.And can not burn when the concentration of gas is less than 5% in air, and while being greater than 16%, can not blasting and not burn yet.Therefore, the accurate detection of gas density just becomes the generation that effectively prevents or avoid this mine disaster of gas explosion.
Be mainly that gas density is detected at present, but majority do not pay close attention to the detection of another two factors, thereby cause monitoring unsuccessfully, accident of mine disaster is still taken place frequently, cause serious personnel or property injury.In addition, during at present monitoring, be that long tunnel internal point of division laying under coal mine is for detection of the sensor of gas density, and by electric wire, connect between each sensor, transfer data to again on aboveground computer analyze, processing etc., when there is gas explosion or burning in down-hole, there is great potential safety hazard in this this electric wire, can become fuse and cause larger disaster.
Summary of the invention
The present invention will solve the problems of the technologies described above, and a kind of gas-warning device is provided, and has real-time detection gas density and causes the factor of its blast or burning, effectively prevents or avoided the generation of gas explosion or burning.
Technical scheme of the present invention is:
A device, comprises and is arranged at down-hole for the harvester of the various ambient parameters of Real-time Collection, and the output of described harvester carries out line with the input of microprocessor and is connected; The output of described microprocessor be connected with respectively warning device with for the power switch of supply line under control well; Microprocessor interactive mode is connected with transistroute, described transistroute by down-hole information by radioing to the host computer of aboveground Surveillance center.
Further, described harvester is connected with microprocessor by amplifier.
Further, described harvester is firedamp sensor, oxygen sensor and temperature pick up; Described warning device is buzzer and alarm lamp.
Further, the output of described microprocessor is connected with LED display.
In the air that gas-warning device of the present invention gathers the gas concentration of firedamp sensor collection and oxygen sensor, temperature pick up, oxygen content and temperature data are transferred to microprocessor after processing by amplifier and process, and show in real time the secure state value after current gas density, temperature, oxygen density value and data fusion.When detected value reaches the alarm point pre-seting, start warning device, buzzer call warning while alarm lamp glimmer, and to remind operator on duty dangerous, take safety measures in time; And when detected value rises to default power-off point, microprocessor driven power switch cuts off power supply, thereby close in time circuit, reduced burning or blast occur gas possibility and harmfulness.So reporting to the police, sound, the light of the present invention by warning device fundamentally greatly avoided the serious accident of gas combustion, blast to occur with the power-off of power switch.Simultaneously by the wireless transmission of transistroute, secure state value after concrete gas density, temperature, oxygen density value and the data fusion of each operating point, down-hole is flowed in time to the host computer of aboveground control centre, reach effective understanding and control to downhole conditions.And reduced length of arrangement wire and workload, also reduce the harmfulness that gas combustion or explosion time produce.
This device has that cost is low, strong adaptability, detect and the feature such as detection alarm is accurate in real time, can be widely used in gas on-the-spot under coal mine and detects and report to the police.
Accompanying drawing explanation
Fig. 1 is theory diagram of the present invention.
The specific embodiment
As shown in Figure 1, a kind of gas-warning device, comprise and be arranged at down-hole for firedamp sensor 1, the oxygen sensor 2 and temperature pick up 3 of the various ambient parameters of Real-time Collection, firedamp sensor 1, oxygen sensor 2 all carry out line by amplifier 4 with the input of microprocessor 5 with the output of temperature pick up 3 and are connected; The output of described microprocessor 5 is connected with respectively LED display 6, warning device 7 and power switch 8 for supply line under control well; Microprocessor 5 interactive modes are connected with transistroute 9, relaying road 9 by by down-hole information by radioing to the host computer 10 of aboveground Surveillance center.
Further, described warning device 7 is buzzer and alarm lamp.
Operating principle:
In the air that the gas concentration of firedamp sensor collection and oxygen sensor, temperature pick up gather, oxygen content and temperature data are transferred to microprocessor after processing by amplifier and process, and on LED display, show the secure state value after current gas density, temperature, oxygen density value and data fusion in real time.When detected value reaches the alarm point pre-seting, start warning device, buzzer call warning while alarm lamp glimmer, and to remind operator on duty dangerous, take safety measures in time; And when detected value rises to default power-off point, microprocessor driven power switch cuts off power supply, thereby close in time circuit, reduced burning or blast occur gas possibility and harmfulness.Wireless transmission by transistroute flows to the secure state value after concrete gas density, temperature, oxygen density value and the data fusion of each operating point, down-hole the host computer of aboveground control centre in time simultaneously, reaches effective understanding and control to downhole conditions.Fundamentally greatly avoided the serious accident of gas combustion, blast to occur.
Above embodiment is not limited only to protection scope of the present invention, all based on basic thought of the present invention, modify or change all belong to protection scope of the present invention.
