Abstract
The utility model relates to a wireless settlement sensor which can measure the settlement of highway embankment, railway embankment, pier, building basement and other buildings. A differential pressure sensor divides the internal space of the wireless settlement sensor to two spaces which are not communicated. One side is air and the other side is liquid. The elevation change is calculated by the change of the size of the pressure.
Description
Affiliated technical field
The utility model relates to a kind of device of measuring sedimentations such as ground, roadbed, bridge, especially can read settlement values long-range by wireless network, on a large scale.
Background technology
At present, the method for settlement measurement mainly is the settlement plate method.This method is simple in structure, directly perceived, still, buries complicated operation underground, has a strong impact on construction and construction speed, and the verticality of connecting link be difficult for to guarantee, the data of a point of energy measurement only, and its shortcoming is more obvious when measuring settlement point in enormous quantities.Whole engineering is done one-shot measurement, needs a large amount of manpowers, the time of continuous coverage tens days even some months.So needs of highway, railway and the bridge construction of the incompatible fast development of this method.
Summary of the invention
Can not be on a large scale in order to overcome existing settlement measurement method, at a high speed, the deficiency of high-acruracy survey settling data, the utility model provide a kind of on a large scale, high-speed, high-precision settling data measuring system, and, the subsidence curve of continuous on-line reflection in time, cheap settlement sensor.
The technical scheme that its technical matters that solves the utility model adopts is: by being linked together identical two or more settlement sensor conjunction measuring settling datas.One of them is fixed on the non-settling foundation stone as with reference to point, the sensor of measurement point, according to the sensor of reference point in the pressure change calculations of liquid go out the settling data of measurement point sensor.In the sensor housing of sealing, a higher precision differential pressure sensor is arranged.Differential pressure pick-up is divided into housing two parts that separate fully.Be air on one side, the another side full of liquid.When the settlement sensor high and low position of measurement point changed, the pressure of liquid changed in the measurement point sensor, and the differential pressure value after changing is converted into height, this height with regard to the time sedimentation numerical value.
The beneficial effects of the utility model are, owing to adopted advanced Single Wire Bus Technology and wireless sensor network technology, and the therefore settling data of large-range measuring settlement point easily.
