Description
Technical field
The utility model relates to a kind of gas-monitoring control device, relates in particular to a kind of colliery mine gas monitor controller.
Background technology
The coal in China reserves are abundant, and coal all is the topmost primary energy of China all the time.Yet coal mining often is accompanied by excessive risk, and coal mining accident constantly takes place, and has caused serious casualties, economy and politics loss.How to strengthen the mine disaster preventing and controlling, how correctly to handle the relation of safety and production, safety and benefit, fulfil the coal mine safety monitoring function how accurately, in real time, fast, guarantee the efficient running of rescue and relief work, safety rescue, become the most important thing of coal mine working.Facts have proved that quickly and accurately mine gas being tested and the data that test draws are made analysis and judgement is very important to reducing mine fire and gas explosion.The coal mine gas check and analysis are the essential bases that ensure mine safety, are the fundamental basis of colliery disaster prevention, improvement and disaster relief decision-making.
Lay the place difference according to equipment, mine fire beam tube monitoring system is divided into ground type and down-hole type.The ground type to ground, adopts the Ground analysis instrumental analysis by " beam tube " suction downhole gas sample, carries out continuous monitoring; But because its exhaust pipe is long, it is relatively poor that the gas sample is analyzed real-time, and be easy to the accuracy of factor affecting gas analyses such as because of the pipeline windage excessive or pipeline principal fault, thereby influence monitoring accuracy, and material, construction and maintenance cost are all very high.The down-hole type is by being placed on the monitoring equipment of down-hole, the parameter of required monitoring is carried out field monitoring sampling, analyzing and processing, thereby avoid the monitoring analysis error brought because of exhaust pipe is long as far as possible, improve the real-time and the accuracy of monitoring, all saved cost greatly in each link simultaneously.Therefore, need a kind of like this colliery mine gas monitor controller:, realize control function such as calculating, sampling, analysis, demonstration, storage and data transmission as the control assembly of colliery mine gas monitoring device.
The utility model content
The purpose of this utility model provides a kind of colliery mine gas monitor controller, carry out by Automatic Program, realize monitoring in real time with the surface work station under the coal mine demand of colliery mine gas, the danger and the electromagnetic interference problem of blast have been eliminated, strong to environmental suitability, can under the environment moist, that dust is more, use, be applicable to coal mine operation.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of colliery mine gas monitor controller, comprise apparatus main body, described apparatus main body is provided with embedded type CPU, datacom chip, storer, analog to digital converter and power supply, described embedded type CPU is connected with datacom chip, storer and analog to digital converter by system bus, described apparatus main body upper end is provided with signal output port, and the apparatus main body bottom is provided with wire jumper.
The beneficial effects of the utility model are: this colliery mine gas monitor controller adopts embedded system, and is powerful, the scene is practical, automaticity is high; Well-designed, science has been arranged a plurality of assemblies and module, and all circuit are all followed explosion-proof design, explosion-proof, safety own, and problems such as explosion danger and electromagnetic interference (EMI) have been eliminated in this intrinsic security; Matching embedded type software by staff's requirement, is finished the Control work such as sampling, analysis, demonstration, storage of colliery mine gas monitoring device, finishes the real-time monitoring of colliery mine gas; The CPU reaction velocity is fast, supports that the real-time multi-task ability is strong, for Control work is laid a good foundation; Each parts is equipped with complete, each telotism; Closure is good, and is strong to environmental suitability, can use long service life under the environment moist, that dust is more; Compact conformation, in light weight, volume is little, convenient installation, maintenance, remarkable benefit.
