Embodiment
Technical scheme is described in further detail with reference to specific embodiment:
The present invention proposes a kind of coupling Critical Rainfall and the double mode mountain torrents pre-alarming control system of soil moisture content saturation degree and side Method, proposition is coupled Critical Rainfall and soil moisture content saturation degree, realizes the generation under two kinds of modes of warning to mountain torrents Carry out more science, in time, it is accurate, comprehensively study and judge and forecast.It is mainly characterized by:First, the system is arranged in mountain torrents Easily hair region, is easy to implement the unmanned remote auto early warning to mountain flood;Second, by monitored area Critical Rainfall threshold value Measuring and calculating, set up the pre-alarming system based on Critical Rainfall;3rd, soil nmoisture content analyser is arranged in the monitoring soil body, determined Go out the water content of the soil body, changed soil moisture content and soil moisture content saturation degree using electronic data interchange device.By soil Earth water content saturation degree is incorporated into the disaster judge to mountain torrents, and more conventional single utilization Critical Rainfall judges the side of mountain torrents Method, establishes more perfect and accurate Alert Standard;Finally, by GPS and mobile communication signal base station, by warning information with mountain torrents Centered on disaster point, the order of severity size occurred according to disaster sets different size of information and pushes radius, accomplishes calamity Evil generation area information all standing, disaster generation area peripheral information in time, the purpose that is accurately sent to.
Currently, territory and meteorological department are mainly by high-resolution satellite and meteorological data to the possible mountain torrents calamity occurred Evil carries out remote sensing monitoring.The control system and method set up one similar to small in the areas adjacent that may occur mountain flood The work station of type meteorological field(Work station is dangerous without mountain torrents Landslide Hazards).Surveyed by the soil moisture in data collecting system Determine water content respectively to the soil body in monitored area of instrument, pluviograph and automatic weather station, 24h rainfalls, wind speed gentle Warm data are gathered in real time;Shone using the PIV particle pictures tester in data collecting system, unmanned plane, high-resolution field Camera is gathered in real time to the internal particle change and external dynamic change of the soil body in monitored area respectively.Cooperation utilizes number According to the electronic data interchange device in conversion and transmission subsystem(EDI)The soil moisture content collected is converted into corresponding soil Water content saturation degree;In addition, using data link by soil moisture content saturation data, 24h rainfall product datas, inside soil body Particle modified-image and soil body external surface layer dynamic image are transferred to disaster and judge subsystem.Formulate and be more defined for relevant department Really, in time, reasonably prevent and treat prediction scheme and transfer measure provides foundation and guarantee.
Currently, the means that mountain flood may be occurred by judging an area are mainly changed by analyzing the meteorological of this area The changing condition of situation, particularly rainfall, coordinates artificial observation experience for many years to formulate preliminary Disaster Assessment report.It is this Method faces many difficult and defects, such as:In the area for having rainfall network or Rainfall data, meteorological, Rainfall data can be coordinated The rainfall in the region is analyzed, so as to be estimated to the probability that mountain torrents occur;And in data deficiencies or non-avaible region, then only Interpolation analysis can be carried out to the rainfall data on periphery, so cause workload not only cumbersome but also forecast precision is not also high.Institute Double mode mountain torrents pre-alarming control system and method are stated, it is small to carry out 24 to rainfall using the pluviograph in data collecting system When continuous acquisition, and the rainfall collected is calculated using the central processing unit in disaster decision-making system, obtains critical rain Amount threshold value and the relation for setting up mountain flood and Critical Rainfall, propose the mountain flood of three different stages based on Critical Rainfall Warning grade.
The control system and method for the present invention, the early warning to mountain flood is incorporated into by soil moisture content saturation degree. Conventional predominantly stays in souring of the rainfall for the soil body for the mechanism that rainfall causes landslide to produce mountain torrents.So And, the change of the water content saturation degree of the soil body itself is only the key factor of the generation of influence mountain torrents or even disaster size.Work as rainfall When generation, with rainwater it is a large amount of under ooze, gradually cause the native rock layers saturation of the soil body, add the weight of gliding mass, reduce The shearing strength of native rock layers.When shear stress has exceeded the shearing strength in the face on a certain slide surface of the soil body, landslide will be caused to produce It is raw, then cause that Freshets roar down from the mountains.So, the water content to the prewarning area soil body carries out dynamic monitoring in real time, for prevention mountain Flood is most important.The mountain torrents pre-alarming control system and method, set the soil moisture content saturation that may cause that Freshets roar down from the mountains Spend threshold value.In the threshold interval, actual rainfall and region are lasted into storm intensity(1h、3h、6h、12h)It is compared, carries Go out the mountain flood warning grade of five different stages based on soil moisture content saturation degree.
In the Hills for occurring mountain flood, its most basic topography and landform character is exactly that massif is numerous, and mountain shape is steep, Soil texture is loose, and easy ponding, cheuch river is dispersed throughout among massif.In addition, meagrely-populated, the personnel that are not easy to garrison for a long time or Contact.The mountain torrents pre-alarming control system and method for the present invention, using unmanned plane and high-resolution field camera in monitored area The soil body internal particle change and the real-time monitoring of external dynamic change, can be in time by the situation of the condition of a disaster when Freshets roar down from the mountains and climing The trend prolonged passes work station back in real time.Further, since mountain area lacks necessary life supply, the electric power support source of whole system The photovoltaic electroplax and small-sized wind energy generating plant installed in system, with the use of battery.When fine, the sun Can electroplax and wind energy plant solar energy, wind energy are converted into work respectively needed for electric energy and by part electrical power storage in battery In.

Central processing unit in system work station sets up the threshold value according to Critical Rainfall the pass of rainfall and Critical Rainfall System(Differentiate 24h rainfall and the multiple proportions relation of Critical Rainfall), it is small according to national mountain flood prevention planning leader in 2003 The establishment of group office《National mountain flood prevention planning mountain flood Critical Rainfall analysis detailed rules of calculation》, propose three kinds of mountain torrents Warning grade:If 24h rainfalls are approximately equal to Critical Rainfall, system is determined as mountain torrents yellow early warning(Three-level);If 24h rainfalls Between 1 times of Critical Rainfall and twice of Critical Rainfall, then system is determined as the orange color early warning of mountain torrents(Two grades);If 24h rainfalls Amount is more than 2 times of Critical Rainfalls, then system is determined as mountain torrents red early warning(One-level).
When rainfall is produced, with rainwater it is a large amount of under ooze, gradually cause the native rock layers saturation of the soil body, add gliding mass Weight, the shearing strength of the native rock layers of reduction.When shear stress has exceeded the shearing strength in the face on a certain slide surface of the soil body, incite somebody to action Cause landslide to produce, then cause that Freshets roar down from the mountains.Therefore, soil moisture content saturation degree and actual rainfall and to last heavy rain strong Degree has contact, affects the judgement that mountain torrents occur.
Central processing unit in system work station will last storm intensity according to monitored area(1h、3h、6h、12h), will The soil moisture content saturation degree threshold value for occurring mountain flood is set to 25%-75%, is somebody's turn to do when soil moisture content saturation degree is less than or greater than During threshold value, the possibility for occurring mountain flood does not occur respectively and necessarily occurred.In this threshold interval, propose that five kinds of mountain torrents are pre- Alert grade:If surveying rainfall not less than 1h point storm rainfalls, system is determined as mountain torrents safe early warning(Pyatyi);If surveying rainfall Amount is between 1h and 3h point storm rainfalls, then system is determined as the low danger early warning of mountain torrents(Level Four);If survey rainfall between 3h and Between 6h point storm rainfalls, then system is determined as in mountain torrents early warning of endangering(Three-level);If surveying rainfall between 6h and 12h point storm rainfalls Between, then system is determined as the high-risk early warning of mountain torrents(Two grades);If surveying rainfall is more than 12h point storm rainfalls, system is determined as The high danger early warning of mountain torrents(One-level).
When respectively by judging that the mountain torrents pre-alarming control system that Critical Rainfall and soil moisture content saturation degree are obtained is present not When with warning grade, the even more serious grade for taking both to judge.
System judges that obtained calamity danger degree can be passed by the data pick-up in data conversion and transmission subsystem Pass early warning system.
