Description
Technical field
The present invention relates to the safety monitoring system in a kind of industrial and mineral place, refer in particular to a kind of mine of being used for, monitoring mining wireless sensor network system based on cable power and independent current source (battery) mixed type belongs to monitoring mining sensor network technique application.
Background technology
The domestic interior monitoring system (detecting as gas) of mine of China all is the form that adopts cable network now, and each transducer all is to provide power supply by power line, the information of utilizing the transmission of twisted-pair feeder or coaxial cable to gather.There is construction, the problem that maintenance cost is high.Along with going deep into of mine, the appearance in new tunnel.Do not have the technical professional, be difficult to install new wired sensor.Simultaneously, along with the growth of transmission line, there is decay in signal, need add incoming trunk, and this has more increased the cost of system.Simultaneously, in the process of construction, circuit is easy to be dug disconnected, in case circuit has broken, does not have professional and technical personnel's maintenance, and whole system is with at a standstill.Here it is why, drop on the annual mining safety monitoring of country nearly 1,000,000,000, but the continuous reason of annual mine gas explosion.Monitoring equipment drops in a large number, but really plays effect seldom.Be exactly because existing wired sensor system, the system maintenance cost is too high, causes attendant's specification requirement is too high.
And in the existing wireless sensor network, each transducer all is an independently system, having independently, power supply (battery) provides energy, wireless network routing algorithm by complexity, the mode by other transducer relayings of detected data is separately transferred to service host, realize function the information gathering and the monitoring of target area.For the wired sensor network, wireless sensor system has huge advantage: the first, there is not the problem of wiring, and the construction of system, construction cost can be reduced to minimum; The second, expansion is convenient, if new tunnel needs to detect, operating personnel are as long as lose a wireless senser at objective, in system server, note the numbering of this initiate wireless senser, and the place is set, just finished the expansion of system.This mode, the system that greatly reduces expand cost and to attendant's specification requirement.3, be convenient to change, if certain faulty sensor, by system server, can be very fast, determine malfunctioning number of sensor and place very easily.Replace malfunctioning transducer with a new wireless senser, and new wireless senser will add whole system automatically.This mode has reduced the expense and the maintenance cost of system maintenance.
But because the finite energy of the battery of wireless senser own, in case running down of battery, whole network will lose its due function.Simultaneously, because if utilize existing technology, there is wireless route complexity in tunnel kind situation complexity, wireless relay enormous amount, the problem of single transmission range limited (10-50 rice).In case certain wireless senser breaks down, deplete as battery, the information gathering of whole system, transmission all may be interrupted.Present wireless senser all is a single type, and any node in the wireless sensor network all is a transducer, wireless repeater, and the aggregate of wireless route.In the spreading, owing to nodal distance, scatter density at wireless senser in mine, electromagnetic media or the like factor in the mine makes the load of each wireless sensor node in whole system be difficult to reach balanced.This just causes, and in the whole system, the life-span of some node is long, and some is because the load of route transmission is very strong, causes the life-span very short.Because the wooden barrel effect,, determined by the shortest node of that life-span probably the useful life of whole system even all nodes can both operate as normal.This single structure has limited the application of wireless sensor network in mine safety is produced.Therefore, necessary this is improved.
For the mine that does not have the sensor installation monitoring system, wireless sensor network can be installed directly.But, in the existing colliery, much adopted the wired sensor monitoring system, country and ore deposit master have dropped into a lot of funds at secure context, reality determined can not be quickly whole system by wired wireless senser monitoring system that is transformed into.If all escalate into wireless sensor network in the mine, just exist funtion part to overlap with existing sensor network, existing equipment cannot utilize, the problem of overlapping investment.Though there is huge advantage in radio sensing network, these reasons all will limit the application of wireless sensor network in mine.
