Described display device, for receive described data processing equipment calculate each wireless sensor unit the temperature data in zone, corresponding coal seam, and shown, when temperature surpasses the temperature warning value arranged, signal timely gives the alarm.
Preferably, described dump spontaneous combustion of coal gangue hill monitor and early warning system also comprises data-storage system, described data-storage system for store described data processing equipment calculate each wireless sensor unit the temperature data in zone, corresponding coal seam.
Be more preferably, described dump spontaneous combustion of coal gangue hill monitor and early warning system also comprises intelligent analysis system, for the dump coal gangue hill temperature history data of reading out data storage system, draw out temperature curve, spontaneous combustion Trendline, carry out the early warning of spontaneous combustion hazard level by the Fitting Calculation.
Beneficial effect of the present invention:
1, in the dump coal gangue hill, 3 D stereo is arranged a plurality of temperature sensors, set up the temperature sensor network, dump diverse location temperature is carried out to real-time data acquisition and processing, solve and can not monitor in real time self-ignition of coal pile, early warning not in time, is processed problem not in place.
2, the wireless senser solid space is arranged, accurately location, solve the problem of position erroneous judgement, can effectively reduce the operation that the managerial personnel scene is repeatedly detected repeatedly.
3, temperature analysis software is analyzed, is calculated, is stored the image temperature data gathered; Draw various temperature curves, Trendline, the simple and clear relation that represents dump temperature and the degree of depth, and the relation of the degree of oxidation of the temperature of dump and coal, reach the timely early warning of warning value, is the provide technical support of later stage to self-ignition of coal pile.
4, in actual applications, by to coal yard spontaneous combustion Analysis on Mechanism and application sensors thermometry, analyze simultaneously various possible disturbing factors (such as: sunlight, season, wait round the clock), and effectively eliminate, go into a set of coal yard spontaneous combustion monitoring real time early warning method, guaranteed to understand in time the ANOMALOUS VARIATIONS of dump temperature.
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, effectively prevent that for taking measures 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.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is further described in detail.
The system architecture schematic diagram that Fig. 1 is the specific embodiment of the invention.
Embodiment
As shown in Figure 1, lay a plurality of wireless sensor unit 2 in dump coal gangue hill 1 solid space, wireless sensor unit 2 reticulates distribution, volume according to dump, and single temperature probe can detection range broadness, determine the number that needs the set temperature sensor in the 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 the data processing, calculate each wireless sensor unit the temperature data in zone, corresponding coal seam, set up the 3-D data volume in its temperature field, location respective temperature sensor spatial relation.
The temperature that the oxidation rate of coal produces during to oxidation is directly proportional, 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 the dump temperature surpasses 60 ℃, accelerate the oxidation of coal, the dump medial temperature is violent the rising just, when the 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, carry out the early warning of spontaneous combustion hazard level by the Fitting Calculation, 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 the 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, provide foundation for eliminating in time spontaneous combustion, take relevant measure, reach the generation purpose that reduces or avoid dieseling.
The present invention is originally to now methodical improvement, directly a plurality of temperature sensors are embedded in dump with the stratiform spatial structure, utilize wireless receiver to receive the data of induction, form wireless monitor by remote data transmission system analyze in time, the displays temperature curve, data are processed, the temperature variation of monitoring dump diverse location, when reaching the temperature warning value, carry out the 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 technical scheme of the present invention to be described, although with reference to preferred embodiment, the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
