The integrated deformation monitoring of 4S system
The utility model relates to the geologic hazard monitoring technical field, is specially the integrated deformation monitoring of a kind of 4S system, can be applicable to fast distortion, the distortion and the deformation monitoring and the deformation early warning of overall process type geologic hazard slowly.
4S refers in particular to following 4 system: GPS (Global Positioning System GPS) in the utility model; GIS (Geographic Information System GIS-Geographic Information System); RS (Remote Sensing remote sensing) and CS (Comunication System communication system).Reorganize according to the proprietary feature of Principles of Computer Composition to GPS, GIS, RS, each system of CS, generation has the new system of close physical structure and data fusion characteristic and new ergasia, and it is integrated that its process and result are called 4S.The integrated deformation monitoring of 4S system is the system that is used for deformation monitoring that turns to fabric with the 4S one.
Because nature and people are the catastrophic failure of geologic function to geologic media; In recent years; In the world wide, China particularly, geologic hazard demonstrates frequently-occurring situation; Mainly comprise avalanche, landslide, rubble flow, surface collapse and ground fissure etc., seriously prestige is assisted the people's the security of the lives and property.Surplus the reservoir and 230,000 in the great geologic hazard body, only having hundreds of Important Project and geologic hazard body to implement with GPS deformation monitoring net is master's long-term continuous monitoring surplus China existing 8.5 ten thousand.Domestic geologic hazard monitoring method mainly comprises at present: crowd anti-(being observed the master with artificial visually examine, dipstick metering etc.), traditional measurement (using traditional instruments such as transit, spirit-leveling instrument, total powerstation), GPS go the rounds to measure (using instruments such as RTK type GPS orientator, total powerstation), GPS deformation monitoring net (using a plurality of fixing GPS monitoring stations to constitute face of land deformation monitoring net).
The crowd is anti-: up to now, " crowd is anti-" method is generally adopted in the most geologic hazard monitoring of China: undertaken regularly or the range estimation of not timing, dipstick metering etc. by the fixed personnel.The defective of this kind method is not have objective standard also not have objective basis, determines whether early warning by litigant's subjectivity.
Traditional measurement: carry out regularly or irregularly measuring with the local traditional instruments such as transit, spirit-leveling instrument, total powerstation that use in units with good conditionsi such as Reservoir region.The defective of this kind method is: receive influence of various factors such as weather (necessary naked eyes intervisibility), manual work; Take time and effort and still seldom arrive valid data (precision is not enough, data are imperfect etc.) after the wealth; And the interval time between twice measurement is very long, and geologic hazard almost occurs in this interval time all.
GPS is touring to be measured: unit with good conditionsi carries out regularly or irregularly measuring with instruments such as the local RTK of use type GPS orientator, total powerstations in the large reservoir reservoir area etc.As far as the geology disaster alarm, this kind method still seldom arrives valid data.The defective of this kind method has three: one, and observation time is too short; The 2nd, receive artificial factor bigger; Three is that interval time between twice measurement is very long.More than 3 cause that precision is not enough, data are imperfect, observation is discontinuous.In fact, geologic hazard almost occurs between twice measurement all.
GPS deformation monitoring net: since the mid-90 in last century, this method is applied gradually, obtains good effect.The crux problem that the method for using a plurality of fixing GPS monitoring stations to constitute face of land deformation monitoring net can not popularize so far is: the one, and the deformation monitoring system price is too high, more than 20 ten thousand yuan/platform of import GPS receiver main frame (the GPS deformation monitoring station host that does not contain gps antenna) needs; The 2nd, system does not match; The 3rd, the system automation degree is low, and use, operation and maintenance aspects all have deficiency.
