Background technology
The soil body on slope or rock mass, affect, under gravity, along certain Weak face or weak band by factors such as river degradation, groundwater activities, rainwater immersion, earthquake and artificial blending rock, integrally or dispersedly the spontaneous phenomenon of inclined slope aspect lower slider, is called landslide.Landslide is a kind of common geologic hazard, and lives and properties and the safety of the mankind in serious threat.Landslide Deformation process generally can be divided into initial deformation, mild distortion and accelerate distortion three phases.According to the deformation stage residing for landslide, slide prediction can be divided into following several stage: long-term, mid-term, short-term, face cunning.In the initial deformation stage, be first that top, landslide starts to occur distortion sign, earth's surface starts to occur interrupted crack, and now the displacement of whole Landslide Deformation is very little; At mild deformation stage, there is more deformation crack in earth's surface, and form the crack of continuous distribution gradually along landslide periphery, and in the unit interval, the displacement of Landslide Deformation is substantially equal, day accumulative displacement amount can reach several millimeters or several centimetres; Acceleration deformation stage, earth's surface starts to have occurred larger displacement, and Landslide Deformation body unit interval intrinsic displacement amount increases gradually, day accumulative displacement amount can reach several centimetres or several tens cm.
Due to the randomness of " burst " characteristic sum landslide displacement Changing Pattern of landslide disaster, complicacy and uncertainty, make accurate forecast come down the time occurred time very difficult.Present stage existing monitoring method, have plenty of instrument and equipment precision not enough, have plenty of and involve great expense, practicality is strong, and the forecast of therefore coming down also does not improve.
The object of the invention is to solve slide prediction and detect the problems referred to above existed, a kind of device utilizing laser displacement sensor to monitor landslide is provided, the present invention realizes and establishes the wireless interaction network of data, has Real-Time Monitoring, tamper-proof, antijamming capability strong, measures convenient, precision advantages of higher.
The present invention includes several laser displacement sensor, regulate support, wireless transport module, Receiving Host, Image Rendering module, alarming controller and target, each laser displacement sensor is connected with wireless transport module signal, wireless connections between wireless transport module and Receiving Host, wired connection between Receiving Host and Image Rendering module, Image Rendering module and alarming controller wired connection; Several laser displacement sensor, adjustment support, wireless transport module, Receiving Host, Image Rendering module and alarming controller overall package are in casing, casing is fixed on fixed bar, fixed bar top arranges solar panel, solar panel is powered to laser displacement sensor, wireless transport module, Receiving Host, Image Rendering module and alarming controller, and solar panel can also keep off the rain for casing; Fixed bar is fixed on the stable basement rock outside landslide, and target is placed on the monitoring point of sliding mass.The data of each laser displacement sensor are sent to Receiving Host by wireless transport module, Receiving Host statistics, arrangement, storage data, then data are passed to Image Rendering module, Image Rendering module draws each point accumulative displacement amount-time, rate of displacement-time curve, the accumulative displacement amount that alarming controller is passed to according to Image Rendering module and rate of displacement, judge whether to give the alarm, play forewarning function;
Target is arranged to netted, be distributed in multiple region, landslide, be placed on monitoring point, multiple spot is monitored simultaneously, not only can judge landslide glide direction according to the difference of each point displacement, accurate measurements landslide dangerous situation more, and monitor multiple point simultaneously, can prevent landslide from avalanche locally occurring and cause damage.
The course of work of the present invention:
Be assembled with several laser displacement sensor, regulate the casing of support, wireless transport module, Receiving Host, Image Rendering module and alarming controller to be fixed on fixed bar, fixed bar top arranges solar panel, solar panel is powered to laser displacement sensor, wireless transport module, Receiving Host, Image Rendering module and alarming controller, and solar panel can also keep off the rain for casing; Fixed bar is fixed on the stable basement rock outside landslide, and target is placed on the monitoring point of sliding mass.According to geologic examination in early stage, choose multiple monitoring point, monitoring point reticulates distribution, then target is fixed on each monitoring point, debug sensor orientation, opening power, measures the initial distance of each laser displacement sensor to target, setting accumulative displacement amount, rate of displacement and the warning critical value in each stage.Support is regulated to be used for regulating and fixation of sensor, the data that laser displacement sensor records by wireless transport module are transferred to Receiving Host, Receiving Host statistics, arrangement, storage data, then data are passed to Image Rendering module, Image Rendering module draws each point accumulative displacement amount-time, rate of displacement-time curve, the accumulative displacement amount that alarming controller is passed to according to Image Rendering module, the critical value of rate of displacement and setting, judge whether to give the alarm, play forewarning function.
Beneficial effect of the present invention:
The present invention adopts laser displacement sensor, can be as accurate as mm rank, the situation of change of the upper each point displacement in landslide can be reflected accurately, and by wireless transport module, complete the wireless transmission of data from laser displacement sensor to Receiving Host, Receiving Host to be for further processing analysis to data, Image Rendering module realizes graphical to data, can visual pattern observation landslide distortion, set up the time-space relationship of displacement, thus accurate measurements landslide mobile trend.The present invention has continuous monitoring, simple structure, simple to operate, precision is high, can in harsh climate environment the plurality of advantages such as normal work.
