The structure has a structure gap 101 formed between adjacent structures 100, and when a safety accident such as collapse occurs, the structure gap 101 is a position where spatial displacement and force change are first exhibited.

The Beidou monitor 103 is connected to the structural body 100 and is positioned outside the structural gap 101; the big dipper monitor 103 is movably connected with a moving ring 106 which elastically moves up and down relative to the structure 100, and when the big dipper monitor 103 generates spatial displacement, the moving ring 106 also moves relatively. The side edge of the moving ring 106 extends outwards to form a connecting strip 104, the connecting strip 104 has an end face facing the structure 100, and two elastic bodies are arranged on the downward end face; the sensor comprises a pressure sensor 105, and the pressure sensor 105 is arranged on the elastic body; the connecting strip 104 spans the structural gap 101, and the two pressure sensors 105 each abut against two adjacently arranged structural bodies 100.

Through two pressure sensor 105 butt on two adjacent structures 100, when there is not relative displacement between two structures 100, pressure sensor 105's pressure value is unanimous, when taking place the space removal of mutual dislocation between two structures 100, because pressure sensor 105 sets up on the elastomer of pre-compaction, the elastomer elasticity activity, and then drives pressure sensor 105's position change to two pressure sensor 105's pressure value then appears changing.

When the vehicle runs and is influenced by slight vibration, for example, the spatial displacement between the structural bodies 100 changes slightly, and the change of the pressure value is within a set value range, so that the background control center does not generate early warning information, and when the change of the pressure value exceeds the set value range, the background control center combines the pressure value and monitoring data of the Beidou monitor 103 to judge whether the change is an abnormal event.

When the space displacement occurs between the structural bodies 100, the Beidou monitor 103 is also displaced, so that the movable ring 106 is movably arranged on the Beidou monitor 103, and the influence of the displacement change of the Beidou monitor 103 on the pressure monitoring of the two pressure sensors 105 can be eliminated.

The elastomer is pre-stressed so that the pressure sensor 105 is guaranteed to constantly abut against the structure 100 within a limited range of displacement variation.

The terminal surface of orientation of connecting strip 104 is equipped with two interval arrangement's mounting groove, and the inner of elastomer is fixed in the mounting groove, and the mounting groove extends out to the outer end of elastomer, and pressure sensor 105 installs the outer end at the elastomer. Therefore, the elastomer can be ensured to have enough elasticity variation distance to meet the requirement of monitoring.

The Beidou monitor 103 is provided with a cylindrical shell, and the periphery of the cylindrical shell is provided with an annular groove which is arranged around the periphery of the cylindrical shell; the upper portion cover of annular groove is equipped with rubberizing ring 108, and the lower part cover of annular groove is equipped with down gluey ring 107, and rubberizing ring 108 and lower gluey ring 107 can extrusion deformation when the pressurized, and when external pressure withdrawed, then can the reconversion.

The moving ring 106 is sleeved in the middle of the annular groove; the upper end surface of the moving ring 106 abuts against the bottom of the upper rubber ring 108, and the lower end surface of the moving ring 106 abuts against the top of the lower rubber ring 107; the upper rubber ring 108 and the lower rubber ring 107 are in a pre-pressed deformation state respectively. Therefore, when adjacent structures 100 are displaced from each other, the Beidou monitor 103 moves along with the adjacent structures, and thus the moving ring 106 can abut against the upper rubber ring 108 or the lower rubber ring 107, so that the movement of the moving ring 106 can be buffered, and the pressure monitoring of the pressure sensor 105 is prevented from being influenced by the moving ring 106 along with the movement of the Beidou monitor 103.

When the structure 100 is reset due to movement in a non-accident space, such as a conventional vibration, the moving ring 106 is reset due to the restoring action of the upper or lower rubber ring 107.

The lower end surface of the moving ring 106 extends towards the periphery to form a flat abutting ring surface 1061, and the abutting ring surface 1061 abuts against the top of the lower rubber ring 107; the bottom of rubberizing ring 108 is equipped with the embedding annular groove, and the embedding annular groove encircles along the bottom of rubberizing ring 108 and arranges, and the up end of shift ring 106 imbeds in the embedding annular groove.

Since the shift ring 106 itself has a weight, the shift ring 106 can be smoothly abutted against the top of the lower rubber ring 107 by providing the lower end surface of the shift ring 106 with a flat abutting end surface. The upper end face of the moving ring 106 is embedded into the embedding ring groove of the gluing ring 108, so that when the moving ring 106 moves upwards relative to the gluing ring 108, the moving ring 106 can accurately abut against the gluing ring 108 to deform upwards, and the phenomenon of abutting dislocation or uneven abutting stress is avoided.

The structure body 100 has a structure end face facing the structure gap 101, the structure end face is provided with a guide groove, the periphery of the guide groove is circular, the depth of the guide groove is gradually reduced along the radial outward extending direction of the guide groove, that is, the guide groove is a circular groove, the depth of the center position of the guide groove is deepest, the depth of the guide groove is gradually reduced along the direction facing the edge, and the whole guide groove is in the shape of a tapered groove.

The sensor comprises a rolling sensor 102 arranged in a structural gap 101, the rolling sensor 102 is in a spherical shape, and the diameter of the guide groove is larger than that of the rolling sensor 102, so that the rolling sensor 102 can roll along the radial direction of the guide groove. Two sides of the rolling sensor 102 are respectively and movably embedded in the guide grooves of the two structural bodies 100; when the two structures 100 are displaced, the two guide grooves are displaced relative to each other, and the rolling sensor 102 rolls in the two guide grooves.

When the two structures 100 are displaced from each other in this way, the displacement may be spatially displaced, and the rolling sensor 102 rolls in the displacement direction by the abutting action of the structure end faces of the structures 100, so that the displacement direction, the moving distance, and the like of the adjacent structures 100 can be determined from the rolling data of the rolling sensor 102. Of course, the rolling data of the rolling sensor 102 and the monitoring data of the beidou monitor 103 can be combined to more accurately determine the spatial movement data of the structure 100.

The periphery of the rolling sensor 102 is covered with an elastic layer, so that the rolling sensor 102 is ensured not to generate a pure rolling phenomenon between the structural end surfaces of the two structural bodies 100, and the monitoring precision is further influenced. When the two structures 100 are spatially displaced, the rolling sensor 102 must roll.

The bottom of guide way is equipped with a plurality of sunken positions, and a plurality of sunken positions are arranged along the radial interval of guide way, and encircle the center of guide way and arrange. Thus, after the spatial movement between the two structures 100 is stopped, the rolling sensor 102 can be fixed to the original position through the recessed position, so as to avoid the original position from being restored due to the slip, thereby facilitating the monitoring of the multiple intermittent spatial movement.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
