Description

Technical Field

[0001] The utility model specifically relates to an array-type MEMS deep displacement intelligent sensor, belonging to the technical field of displacement sensors. Background Art

[0002] The measurement of deep displacement of underground soil has always been the focus of geological disaster monitoring. Inclinometers are widely used in landslide and foundation pit monitoring. Array displacement meters are a type of inclinometer that is composed of intelligent measurement units that can measure inclination in series and realize dynamic or static three-dimensional displacement monitoring through conversion. They are widely used in earth-rock dams, embankments, building foundations, mines, foundation pit excavation, rock and soil slopes and other safety monitoring fields. Since the inclinometer uses a catheter with a fixed groove and a certain strength, it is difficult for the catheter to sense the damage and loss of karst collapsed soil. With the maturity of MEMS technology, the integration of gyroscopes and accelerometers is miniaturized, low-cost, and buried in series deep displacement sensors have become possible. Array MEMS deep displacement intelligent sensors can measure online for a long time, and displacement measurement information can be reported in real time. Combined with BIM technology, dynamic modeling of geological structure changes can be realized.

[0003] At present, the flexible inclinometer mainly utilizes the angle changes of the sensor in the X, Y, and Z axes to sense the changes in the environment. At the same time, it requires multiple sensors to be supported in series with hard tubes and flexible connecting parts to achieve this. In order to solve the problems of waterproofing and sensor direction consistency, the flexible inclinometer is a professional customized product and needs to be customized and processed by professionals in the factory. After customization, the length and direction cannot be adjusted. All of them are disposable products, so there are the following problems: if the on-site construction situation is inconsistent with the customized length, the entire flexible inclinometer will be scrapped. When the number of sections in series is large, the entire flexible inclinometer is large and very heavy, and it is very difficult to transport to the dangerous slope, which causes great difficulties for construction. After customization, it is large in size and there is no way to do deep water testing. Customized products rely entirely on manual experience, quality is difficult to control, and the cost is very high. Customization on demand cannot be reused.

[0004] In view of this, this application is filed. Utility Model Content
