[0024] Reference Figure 1-2 The figure shows a preferred embodiment of the present invention.

[0025] The highway safety three-dimensional monitoring device based on the Beidou positioning system includes a background control center, a Beidou monitor set on a road base layer 101 and monitoring the spatial movement data of the road base layer 101, a Beidou base station and a pressure roller 200 installed at a position to be monitored on the highway. The background control center establishes a visualized three-dimensional model of the highway. According to the actual size ratio and location information of the structure, a three-dimensional model is established in the background control center through three-dimensional modeling. The Beidou monitor communicates with the Beidou satellite through the Beidou base station.

[0026] By combining BeiDou satellites with BeiDou monitors, centimeter-level spatial displacement monitoring can be achieved, realizing high-precision monitoring. In this embodiment, the BeiDou monitor of Hunan Lianzhi Technology Co., Ltd. is used to monitor the spatial displacement of the structure.

[0027] The pressure roller 200 is arranged in the soil 100 below the roadbed 101 and is extended along the width direction of the roadbed 101; a strip-shaped pressure sensor is attached to the surface of the pressure roller 200, and the pressure sensor is extended along the axial direction of the pressure roller 200; in this way, the pressure data of the roadbed 101 can be monitored by the pressure sensor, and a positioner is provided inside the pressure roller 200 to monitor the position of the pressure roller 200. When the roadbed 101 is damaged or other problems occur, the position of the pressure roller 200 will change.

[0028] The outer circumference of the Beidou monitor is surrounded by a rotating ring, which is driven by a motor to rotate relative to the Beidou monitor. The rotating ring is connected to a solar panel arranged tilted downward, and a photosensitive sensor is provided on the solar panel. The solar panel collects solar energy to provide power for the Beidou monitor, and by setting a photosensitive sensor, the direction of sunlight can be monitored. The rotation of the rotating ring driven by the motor can make the solar panel face the sun at any time to ensure sufficient power.

[0029] The pressure sensor and locator communicate with the background control center through the wireless network, and embed the pressure data and positioning data in the three-dimensional model for display. The Beidou monitor transmits the spatial movement data of the collected roadbed to the background control center in real time through the Beidou base station and Beidou satellite, and the background control center embeds the spatial movement data in the three-dimensional model for display.

[0030] The above-mentioned three-dimensional highway safety monitoring device based on the Beidou positioning system monitors the pressure data of the roadbed 101 by arranging a pressure sensor on the pressure roller 200, and sets a positioner inside the pressure roller 200 to monitor the positioning data of the pressure roller 200. By monitoring the pressure data and the positioning data, the state of the roadbed 101 can be monitored at any time, and the pressure data and the positioning data can be embedded in the three-dimensional model for display; through the positioning monitoring of the Beidou monitor and the Beidou satellite, the spatial displacement of the roadbed 101 can be accurately monitored, and by establishing a three-dimensional model of the highway, the spatial displacement data monitored by the Beidou monitor is embedded in the three-dimensional model, and the spatial displacement data of the roadbed 101 can be monitored anytime and anywhere, and the three-dimensional model can be intuitively displayed to achieve high-precision three-dimensional safety monitoring for the highway, and achieve the effects of early warning and emergency command.

[0031] When an abnormality occurs in the roadbed 101 of the highway, the three-dimensional model of the background control center combined with the monitoring data of the Beidou monitor can quickly determine the exact location of the accident and achieve the effect of rapid emergency command.

[0032] The bottom of the Beidou monitor is provided with a mounting base fixed on the roadbed 101, and the mounting base is provided with a mounting groove 404 with an upper opening. The lower part of the Beidou monitor is embedded and fixed in the mounting groove 404. There is an installation gap between the bottom of the Beidou monitor and the bottom of the mounting groove 404. The installation gap is filled with elastic mounting blocks, and the elastic mounting blocks are in a pre-compressed state.

[0033] In this way, when the roadbed layer 101 vibrates normally, the mounting base will vibrate, and the Beidou monitor will also vibrate. The elastic mounting block can buffer the up and down vibrations of the Beidou monitor, thereby protecting the Beidou vibrator. The vibration data of the roadbed layer 101 can be obtained through the up and down vibrations of the Beidou monitor.

[0034] The mounting seat includes a ring seat 400 fixed on the roadbed 101 and a seat body 403. The ring seat 400 encloses an inner ring space 401. The seat body 403 is located in the inner ring space 401. There is a gap between the outer periphery of the seat body 403 and the inner side wall of the ring seat 400. The inner side wall of the ring seat 400 is provided with a plurality of inclined bars 402. The plurality of inclined bars 402 are arranged at intervals along the circumferential direction of the inner side wall of the ring seat 400. The outer ends of the inclined bars 402 extend obliquely toward the middle of the inner ring space 401 and are fixedly connected to the outer periphery of the seat body 403. A mounting groove 404 is provided in the seat body 403.

[0035] In this way, as the roadbed layer 101 vibrates, since the ring seat 400 is fixed to the roadbed layer 101, as the roadbed layer 101 vibrates, and the seat body 403 and the ring seat 400 are connected by the inclined inclined bar 402, the inclined bar 402 plays a role of vibration buffering. Combined with the elastic effect of the elastic mounting block, the mounting seat performs a secondary buffering effect on the Beidou monitor, thereby protecting the Beidou monitor and more accurately obtaining the vibration data of the roadbed layer 101.

[0036] In this embodiment, the adjacent inclined strips 402 have different inclined directions, so that they can play a buffering and regulating role in both the upward and downward directions.

[0037] Extension strips 201 extend outward from both sides of the pressure roller 200 , respectively. The extension strips 201 are arranged along the axial direction of the pressure roller 200 . The pressure sensor includes two side pressure sensors, which are arranged on the extension strips 201 and toward the roadbed layer 101 .

[0038] By setting extension strips 201 and side pressure sensors on both sides of the pressure roller 200, under normal conditions, the pressure data of the two side pressure sensors are not much different. When the road base layer 101 has faults or ruptures, the pressure data of the two side pressure sensors change significantly, thereby enabling real-time monitoring and early warning of the fault and dislocation phenomenon of the road base layer 101.

[0039] The extension strip 201 is arranged in parallel with the roadbed layer 101 , so that the side pressure sensor disposed on the extension strip 201 can monitor the pressure data of the roadbed layer 101 more accurately.

[0040] A flat end surface 202 facing downward is formed at the bottom of the pressure roller 200 . The flat end surface 202 is extended along the axial direction of the pressure roller 200 , so that the pressure roller 200 can be firmly fixed in the soil 100 under normal conditions.

[0041] The pressure sensor includes a bottom pressure sensor, which is arranged on the flat end surface 202 and away from the roadbed 101. In this way, when the soil 100 below the roadbed 101 is dislocated or settled, it will drive the pressure roller 200 to roll. At this time, the pressure data of the bottom pressure sensor will change, so that the settlement and dislocation of the roadbed 101 can be monitored.

[0042] A plurality of insertion rods 203 are provided at the bottom of the pressure roller 200 , and the plurality of insertion rods 203 are arranged at intervals along the axial direction of the pressure roller 200 , and the insertion rods 203 are inserted into the soil body 100 . In this way, the pressure roller 200 is conveniently fixed in the soil body 100 .

[0043] The highway safety three-dimensional monitoring device based on the Beidou positioning system includes a transverse bar 300 placed in the soil 100 below the roadbed 101, and the transverse bar 300 is extended along the width direction of the roadbed 101; strain gauges 301 extending upward are respectively arranged on both sides of the transverse bar 300, and along the direction from bottom to top of the roadbed 101, the strain gauge 301 is arranged away from the transverse bar 300, and the top of the strain gauge 301 abuts against the bottom of the roadbed 101.

[0044] When the roadbed layer 101 sinks or moves out of position, the strain data of the two strain gauges 301 will change, so that the sinking and moving out of position of the roadbed layer 101 can be accurately monitored.

[0045] The strain gauge 301 is in a pre-deformed state, so that the strain gauge 301 can always abut against the bottom of the roadbed layer 101 .

[0046] The top of the strain gauge 301 is arranged away from the transverse strip 300 and extends outward to form a sheet-shaped abutting end 302, and the abutting end 302 abuts against the bottom of the roadbed 101. In this way, by providing the sheet-shaped abutting end 302, the strain gauge 301 can be better abutted against the bottom of the roadbed 101, and the abutting area is increased, so as to better monitor the settlement strain of the roadbed 101.

[0047] The abutting end 302 is provided with a plurality of protruding structures. Since the bottom of the roadbed layer 101 may be uneven, the abutting end 302 can always abut against the bottom of the roadbed layer 101 by providing the protruding structures.

[0048] The strain gauges 301 on both sides of the transverse strip 300 are arranged in a staggered manner, so that not only the settlement or dislocation movement at the same position of the roadbed layer 101 can be monitored, but also the settlement or dislocation movement in the inclined direction can be monitored.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
