The angle displacement sensor is mounted on the supporting frame, one end of the multistrand fine wire rope and supporting frame are respectively relatively fixed on the slope body or non-movable rock body, another end of the multistrand fine wire rope is winded round angular displacement sensor, then the slided dimension of said slope body can be converted into line displacement by means of multistrand fine wire rope, and the line displacement can be converted into angular displacement by means of angular displacement sensor.
Description
Technical field
The present invention relates to a kind of displacement measurement method and device, geologic body surface displacement measuring method and devices such as particularly a kind of measurement landslide or high slope.
Background technology
At present, the monitoring of landslide or high slope has many kinds, mainly contains methods such as surface displacement dynamic observes, deep displacement dynamic observes, hydrogeology is observed, face of land hydrologic observation.Wherein, deep displacement dynamic observes and is divided into tiltmeter method, radioisotope method, resistance wire sheet method, Metal Ball method etc.In order to grasp the dynamic change of the surperficial each several part in landslide, need carry out surface displacement observation.Observation procedure is a lot, the most frequently used method is exactly the GPS global positioning system total powerstation of unifying, also have to be exactly GPS receiver and electronic total station or robot measurement are linked together, be exactly so-called super total powerstation or super robot measurement, it is the perfect adaptation of real-time dynamic positioning technology and the total powerstation three-dimensional measurement technology of GPS.But, these two kinds of measuring methods all have the shortcoming that is difficult to overcome, that is exactly under conditions such as greasy weather or rainy day, or under other atrocious weather condition, GPS real-time dynamic positioning technology and total powerstation three-dimensional measurement technology all are difficult to realize, perhaps promptly enable to survey, its precision is also very low, and in the most probable generation of under heavy rain or other severe weather conditions, coming down just.
Summary of the invention
Problem at the prior art existence, the objective of the invention is to: overcome the real-time dynamic positioning technology of GPS and total powerstation three-dimensional measurement technology under conditions such as greasy weather or rainy day, or under other atrocious weather condition, be difficult to the accurately shortcoming of measurement, and then provide a kind of round-the-clock landslide surface displacement measuring method and device, it can be under conditions such as greasy weather or rainy day, or under other atrocious weather condition, also can measure exactly.
The object of the present invention is achieved like this: a kind of slope surface displacement measuring method of the present invention:
One end of multiply seizing wire is fixed on the sliding mass, and the other end is fixed on the motionless object or on the basement rock body, twines an angular displacement sensor on the multiply seizing wire; When sliding mass slides with respect to motionless object or basement rock body, the length of multiply seizing wire will change between the two-end-point, and drive angular displacement sensor simultaneously and rotate, the variable quantity of the length of multiply seizing wire has just reflected the slippage of sliding mass between the two-end-point, this moment, described multiply seizing wire drove described angular displacement sensor rotation, just can converse slope surface displacement by the measured angular displacement.
The present invention and then a kind of slope surface displacement measurement mechanism is provided, comprise: angular displacement sensor, support and multiply seizing wire, angular displacement sensor is installed on the described support, one end of described multiply seizing wire and described support difference relative fixed are on sliding mass, the other end is fixed on the motionless object or on the basement rock body, the multiply seizing wire is wrapped on the described angular displacement sensor, and the variation of described multiply seizing wire length is measured with angular displacement sensor.
Further, also comprise a data radio transmission system, the size of described angular displacement is sent to data processing centre (DPC) by this data radio transmission system.
Further, also comprise a gimballed base bearing, the base that it can adapt to the established angle displacement transducer rotates arbitrarily, to adapt to the variation of wire rope direction.
Further, also comprise a guide bearing, described multiply seizing wire is through any rotation of this guide bearing with adjustment established angle displacement transducer chassis.
Further, described angular displacement sensor is conductive plastics angular displacement sensor or angular encoder or grating angular displacement sensor.
The invention has the advantages that: the present invention is owing to adopted little and the angular displacement sensor that sensitivity is very high of driving torque, make that the measuring accuracy of sliding mass displacement is very high, and can change measuring accuracy by the diameter that changes the sensor rotor wheel as required.Even under conditions such as greasy weather or rainy day, or under other atrocious weather condition, particularly under the most possible heavy rain condition that takes place to come down, the present invention still can measure the landslide surface displacement in real time and be transferred to the land slide data processing enter by radio transmitting device.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment:
