Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-7A roadbed settlement monitoring device based on satellite positioning includes a central processing unit and a reference groove 2 opened above the ground to be measured 1. The ground to be measured 1 includes a surface layer 101 above and a deep buried layer 102 below. The reference groove 2 passes through the surface layer 101 and is connected to the deep buried layer 102. A fixed column 3 is provided inside the reference groove 2. The bottom of the fixed column 3 is inserted into the deep buried layer 102. The circumferential side wall of the fixed column 3 is provided with an anti-collapse layer 4. A signal transmitter 5 is fixed to the upper end of the fixed column 3. A plurality of Detection slot 6, the inner wall of each detection slot 6 is fixed with a mounting block 7, the upper ends of multiple mounting blocks 7 are provided with a limit slot 8, the interior of each limit slot 8 is sealed with a support column 9, the upper end of each support column 9 is fixed with multiple vertical support plates 10, the upper ends of multiple vertical support plates 10 are commonly fixed with a protective block 11, each protective block 11 is provided with a signal receiver 12, the interior of each mounting block 7 is provided with multiple groups of movable limit devices, and the multiple groups of movable limit devices are arranged at equal distances in the vertical direction. A rotating separation device is provided inside. Through the fixed column 3 stably fixed in the reference groove 2 and the support column 9 fixed in the roadbed, the signal transmitter 5 on the fixed column 3 and the signal receiver 12 on the support column 9 transmit and receive signals, which are converted into three-dimensional coordinates by the signal conversion module. By observing the offset distance of the signal receiver 12 in the three-dimensional coordinates at different times, the settlement of the roadbed at that location can be detected. Monitoring the roadbed settlement in this way can make the settlement monitoring more accurate and wider in scope. A plurality of diagonal bracing columns 14 are fixed to the circumferential side walls of the fixed column 3, and a protective cover 13 is fixed to the upper ends of the plurality of diagonal bracing columns 14. The protective cover 13 is located directly above the signal transmitter 5, and the protective cover 13 is sealed against the inner wall of the reference groove 2; a plurality of vertical columns 15 are provided above the ground to be measured 1, and a solar panel 16 is fixed to the upper end of each vertical column 15, and a storage block 17 is fixed to the end of each vertical column 15, and a battery 18 is provided inside each storage block 17, and the plurality of solar panels 16 are connected to the plurality of batteries 18 in a one-to-one correspondence.

[0027] The movable limit device includes two horizontal grooves 19 on the inner walls on both sides of the limit groove 8, and each horizontal groove 19 is slidably connected to a moving block 20. One end of each moving block 20 is fixedly connected to the inside of the horizontal groove 19 by a plurality of connecting springs 21, and the other end of the moving block 20 is fixed with two blocking blocks 22; multiple blocking blocks 22 are spaced at the same distance in the vertical direction, and the side wall of the support column 9 is penetrated by a through groove 23, one group of blocking blocks 22 is against the inside of the through groove 23, one group of blocking blocks 22 is against the bottom of the support column 9, and the other multiple groups of blocking blocks 22 are against the side walls of the support column 9. By arranging multiple groups of blocking blocks 22 arranged at equal distances in the vertical direction inside the limit groove 8, the installation position of the support column 9 can be easily adjusted, and the installation position of the signal receiver 12 can be appropriately adjusted according to the situation above the ground 1 to be measured, which can facilitate installation and use in different roadbed environments and effectively increase the practicality of the roadbed settlement device.

[0028] The rotating separation device includes a vertical rotating rod 24 rotatably connected to the upper end of the support column 9 through a bearing, and the circumferential side walls and bottom of the vertical rotating rod 24 are fixed with protrusions 25, one of which is located inside the through groove 23 and abuts against the block 22, and the other protrusion 25 is located at the bottom of the support column 9. The side walls of multiple vertical support plates 10 are commonly fixed with a horizontal fixing plate 26, and the upper end of the horizontal fixing plate 26 is rotatably connected with a locking rod 27. The locking rod 27 is a threaded rod with a small pitch. When it rotates half a circle, the up and down movement range is small. The bottom of the locking rod 27 is fixed to the upper end of the vertical rotating rod 24; the inner wall of each protective block 11 is fixed There are partitions 28, and multiple warning lights 29 are set on the upper end of each partition 28. They are red lights. The protective block 11 is made of transparent material, and the multiple warning lights 29 are evenly distributed in a circle. Multiple batteries 18 are connected to the signal transmitter 5, multiple signal receivers 12 and multiple warning lights 29. By setting a rotating separation device, the vertical rotating rod 24 and the protrusion 25 are rotated by rotating the locking rod 27, so that the block 22 can be separated from the through groove 23, and then the support column 9 can be quickly removed, which facilitates the disassembly and maintenance of the signal receiver 12 and the subsequent reuse, and can reduce the waste of resources.

[0029] The central processing unit is electrically connected to a data conversion module, the data conversion module is electrically connected to a signal transmitter 5 and a plurality of signal receivers 12, the central processing unit is electrically connected to a data center, the central processing unit is electrically connected to a remote control module, and the central processing unit is electrically connected to an alarm module and a Beidou positioning module. By using the Beidou positioning module and the alarm module, the roadbed with larger settlement can be located and sampled, and the red warning light 29 powered on inside the protective block 11 can be used to warn of the position of the roadbed with larger settlement, while facilitating quick inspection and maintenance by maintenance personnel, and facilitating safe monitoring of the roadbed. The alarm module, the signal transmitter 5 and the signal receiver 12 are electrically connected to a power supply module, which is composed of a battery 18, and is convenient for roadbed settlement monitoring in a relatively remote environment.

[0030] In the present invention, when monitoring the settlement of a roadbed, it is first necessary to open a plurality of evenly spaced detection grooves 6 on the surface layer 101 of the roadbed, and fix the mounting blocks 7 to the inside of the detection grooves 6. At the same time, a reference groove 2 is opened through the roadbed, and the fixing columns 3 are inserted into the deep buried layer 102. At the same time, the anti-collapse layer 4 outside the fixing columns 3 is combined to achieve a stable connection between the fixing columns 3 and the deep buried layer 102, thereby ensuring the stable placement and use of the fixing columns 3 inside the reference groove 2.

[0031] Then, by aligning the positions of the limit groove 8 and the support column 9, the support column 9 is vertically inserted into the limit groove 8. After the bottom of the support column 9 abuts against the upper end of the block 22, the locking rod 27 is rotated as a threaded rod, so that the locking rod 27 can rotate stably half a circle along the horizontal fixed plate 26, thereby driving the vertical rotating rod 24 to use the rotation of the protrusion 25 to push the blocks 22 at both ends to move, thereby enabling the moving block 20 to slide along the inner wall of the horizontal groove 19, and at the same time, the compression of the connecting spring 21 can be achieved. After the block 22 is separated from the support column 9, the support column 9 can continue to move downward. When the block 22 reaches the position of the through slot 23, the connecting spring 21 in the compressed state will drive the moving block 20 to return to its original position, so that the block 22 can correspond to the through slot 23, and then the support column 9 can be limited. At the same time, the bottom of the support column 9 will be against the next set of blocks 22, which can make the connection stability of the support column 9 better. By continuously rotating the locking rod 27 and the vertical rotating rod 24 back and forth, the support column 9 can be further moved downward, so that the installation height of the protective block 11 can be adjusted according to the surface conditions of the roadbed, which is suitable for settlement monitoring of roadbeds in different environments.

[0032] When the signal receiver 12 needs to be disassembled for maintenance, the locking rod 27 is rotated so that the locking rod 27 drives the vertical rotating rod 24 and the protrusion 25 to rotate, so that the block 22 is separated from the through groove 23. At this time, the multiple groups of blocks 22 are corresponding to the outer wall of the support column 9. At this time, the protective block 11 and the support column 9 can be quickly removed by moving the support column 9 upward, thereby facilitating the disassembly and maintenance of the signal receiver 12 and subsequent reuse. The mounting block 7 can be inserted above the roadbed during roadbed construction, which can make the installation and disassembly of the roadbed settlement detection device relatively simple and convenient for reuse of the roadbed settlement monitoring device.

[0033] After the equipment in the reference tank 2 and the detection tank 6 is installed, multiple signal receivers 12 are used to receive the GPS signals emitted by the signal transmitter 5, and the collected signals are processed by the signal conversion module so that the signal receiver 12 and the signal transmitter 5 can be displayed on the three-dimensional coordinates. Therefore, the settlement of the roadbed at that location can be detected by observing the offset distance of the signal receiver 12 in the three-dimensional coordinates at different times. Monitoring the roadbed settlement in this way can make the settlement monitoring more accurate and wider in scope. Moreover, by providing a protective block 11 that is easy to adjust in height, the parking height of the signal receiver 12 can be adjusted, which is convenient for multiple detections at different heights. This can make the settlement monitoring more accurate and convenient for roadbed settlement monitoring.

[0034] By setting up multiple solar panels 16, light energy can be absorbed and converted, which is convenient for the supply of electric energy to the battery 18. The signal transmitter 5 and the signal receiver 12 are powered by multiple batteries 18, which facilitates the use of the roadbed settlement monitoring device in relatively remote environments. Moreover, the roadbed monitoring time can be remotely controlled through the remote control module, and the roadbed settlement monitoring results can be quickly viewed. When the theoretical roadbed settlement is large, the Beidou positioning module is used to locate, photograph and sample the area with large settlement, which is convenient for quick viewing of the actual situation of the roadbed. The use of multiple energized red warning lights 29 can serve as a warning for parts of the roadbed with large settlement, which is convenient for preventing accidents and facilitating the search of maintenance personnel, thereby facilitating the maintenance and use of the roadbed.

[0035] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
