5, manufacture craft is simple, and it is convenient to lay, and with low cost, it is convenient to monitor, and is conducive to promote the use of.The deployment cost of native system temperature sensor and wireless monitor network is low, successful, can find in time coal yard (coal gangue hill) spontaneous combustion origin, for taking measures, effectively prevent that the spontaneous combustion of coal yard from providing great help, energy-saving and emission-reduction also played to obvious effect simultaneously.There is important society and economic benefit, be worthy of popularization.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further described in detail.
Fig. 1 is system architecture schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, in dump coal gangue hill 1 solid space, lay a plurality of wireless sensor unit 2, wireless sensor unit 2 reticulates distribution, according to the volume of dump, and single temperature probe can detection range broadness, determine the number that needs set temperature sensor in dump coal gangue hill, and make number in minimum as far as possible, realize cost savings.Require temperature variation in temperature sensor temperature detection responding range, its shell possesses the functions such as anticorrosive, moistureproof simultaneously.The measurement range of temperature sensor is wide, and detection range can continuous several times be used deeply.
The communication that network data transmission device 4 receives wireless network data and retransmission unit is sent is to central processing server 5.Central processing server 5 by hub 6 connect respectively display terminal T1, T2 ..., Tn, and Database Systems 7.Central processing server comprises data processing equipment and intelligent analysis system, the information of sending according to treating apparatus 5 receiving network data transmitting devices 4, carry out data processing, calculate each wireless sensor unit the temperature data in region, corresponding coal seam, set up the 3-D data volume in its temperature field, location respective temperature sensor spatial relation.
The oxidation rate of coal is directly proportional to the temperature that when oxidation produces, and experiment shows, the oxidation rate of coal often increases 1 ℃ in the time of 30-100 ℃, and oxidation rate just improves 2.2 times.When dump temperature surpasses 60 ℃, accelerate the oxidation of coal, dump medial temperature is violent rising just, when dump temperature reaches 100 ℃, within 1-2 days, can reach involuntary ignition temperature (kindling point of coal is about 260-350 ℃ of left and right), and coal just starts spontaneous combustion.The dump coal gangue hill temperature history data of intelligent analysis system reading out data storage system, draw out temperature curve, spontaneous combustion Trendline, by the Fitting Calculation, carry out the early warning of spontaneous combustion hazard level, find early dump self-heating, spontaneous combustion sign, judgement self-heating, spontaneous combustion state, spontaneous combustion situation to dump is carried out status monitoring, from face, realizes the real-time monitoring to dump coal gangue hill.When there is the abnormal temperature warning value over setting in temperature, signal timely gives the alarm, inform that spontaneous combustion may occur keeper's dump coal gangue hill, and the approximate location of self-ignition of coal pile, for eliminating in time spontaneous combustion, provide foundation, take relevant measure, reach the generation object that reduces or avoid dieseling.
The utility model is originally to now methodical improvement, directly a plurality of temperature sensors are embedded in dump with stratiform spatial structure, utilize wireless receiver to receive the data of induction, form wireless monitor by remote data transmission system analyze in time, displays temperature curve, data are processed, the temperature variation of monitoring dump diverse location, when reaching temperature warning value, carries out high temperature early warning in real time.Take ahead of time relevant measure, for eliminating in time spontaneous combustion, provide foundation, reduce or avoid the generation of dieseling.
It should be noted last that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
