Description
Technical field
The present invention relates to a kind of rubble flow, landslide detection method and device, belong to embedded technology, the network communications technology, tilt detection technology and full-view video image and obtain the application of technology, mainly be applicable to and pass through the take place frequently detection of disasteies such as the along the line and crowd residence of along the line, the highway of railway in area of rubble flow, landslide in disaster context of detection such as rubble flow, landslides.
Background technology
On May 23rd, 2010 was caused the landslide buried line because of rainfall day after day, by K859 the passenger train generation off-line accident of Shanghai Nankai toward Guilin, accident causes 19 people's death, 11 people's severe injuries, 60 people's slight wounds, judge through on-the-spot initial analysis, cause the reason of this incident to be, because the spot falls heavy rain recently, causes massif to come down suddenly.The railway top of train process is highways for 20 meters, and the 20 meters massifs in highway top cave in about 8000 cubic metres of the body that caves in.In train operation, the body that caves in falls through highway, causes train generation off-line accident.The extreme meteorologic phenomena that warmization of the earth brought increases day by day, and on the other hand, the construction of highway, railway is apace to the mountain area deepening, and disasteies such as rubble flow, landslide are also increasing day by day to the people's life and the harmfulness that trip causes; Therefore how in time to detect and to forecast the generation of rubble flow, landslide, the loss that reduces people's lives and properties is had crucial meaning.
Chinese invention patent number is 200610154828.8 to have invented a kind of debris flow early-warning predictor based on omni-directional visual, and this invention mainly is made of rainfall detecting unit, rubble flow generation detecting unit, rainfall raininess computing unit, the relevant hydrometeorological historical record mnemon of rubble flow, debris flow early-warning forecast unit, statistics early-warning forecasting model, debris flow early-warning forecast information release unit etc.; Import as state according to 10 minutes raininess that calculated, one hour raininess, actual effect rainfall, judge probability that rubble flow takes place and seriousness and the urgency level that the probability and the mud-stone flow disaster of rubble flow do not take place under this status condition by the statistics early-warning forecasting model; Judged result in time is distributed to the resident in the disaster explosive area in downstream with network and other various means, makes the resident can in time obtain early warning information, avoid loss, alleviate the disaster of rubble flow thereby can take preventive measures in advance.Chinese invention patent number is 200610154827.3 to have invented a kind of mud-stone flow disaster pick-up unit based on omni-directional visual, comprise the omnibearing vision sensor that is used to monitor massif to be measured and rainfall gathering-device water level, the rainfall gathering-device carries out the microprocessor that disaster detects with being used for according to vision signal, described omnibearing vision sensor is installed in the top of the ditch bed of massif to be measured, described omnibearing vision sensor output connecting microprocessor, described rainfall gathering-device comprises water container, tipping bucket, described tipping bucket is provided with the buoy that is used to show the water container water level; Described microprocessor comprises vision sensor calibration module, buoy position acquisition module, rainfall intelligence computation module, excites rubble flow raininess computing module, debris flow early-warning module.Above-mentioned two patent documents all adopt the mode that detects rainfall and raininess to infer the generation of rubble flow indirectly.At present more rarely seen for the means of direct detection rubble flow, main still is by people's observation.Disaster always will take place, and this also is a kind of natural law of outwardness.Adopting monitoring instrument, computing machine and wireless communication technology is a kind of effective means that the loss that disaster causes is minimized in conjunction with carrying out automatic monitoring forecast.
Because relatively difficulty, the more abominable zone of external environment condition of poor, the electric power supply of some communication conditions often, area takes place for rubble flow, landslide, therefore designed pick-up unit must adopt and possess wireless communication ability, that (as: high temperature, high humidity, sand and dust, thunder and lightning etc.) can work reliably and with long-term under the influence of abominable external environment condition, low-power consumption and self-powered design; In addition, the generation of rubble flow, landslide is often regional extensively, time of origin has uncertainty, and therefore designed pick-up unit must satisfy the requirements such as sensing range, Event triggered warning and remote acknowledgement in wide zone; Consider that from the installation and maintenance angle designed pick-up unit must satisfy convenient for installation and maintenance, can carry out from calibrating pick-up unit long-range.
Summary of the invention
Mainly depend on artificial investigation in order to overcome existing rubble flow, landslide detection means, find untimely etc. deficiency, the invention provides a kind of comprehensive perception detection method, omni-directional visual confirm zone, full spectrum information issue means, safeguard adjust simple, real-time and safe reliability by force, low-power consumption, the rubble flow based on omnibearing tilt sensor and omnibearing vision sensor of Event triggered, the detection method of caving in and device.
