Description

Technical Field

[0001] This invention relates to the field of millimeter-wave radar equipment technology, specifically a millimeter-wave radar device for monitoring tunnel deformation. Background Technology

[0002] As a key node in the transportation network, the structural health of tunnels directly affects traffic safety and the lifespan of the project. Especially under the long-term influence of geological pressure and vehicle loads, tunnels are prone to minor deformations such as arch settlement and sidewall displacement. In order to detect these deformations in a timely manner, millimeter-wave radar equipment for tunnel deformation monitoring is generally used to monitor tunnel deformation.

[0003] Existing millimeter-wave radar equipment for tunnel deformation monitoring has the following shortcomings:

[0004] Millimeter-wave radar equipment is usually mounted directly on a bracket. When it is damaged and needs to be repaired, it is generally necessary to rely on scaffolding or aerial work platforms to carry out high-altitude operations. This not only prolongs the repair time and reduces the efficiency of the operation, but also incurs additional costs due to scaffolding materials, work platform rentals, and labor input, resulting in unnecessary consumption of resources and reducing the effectiveness of millimeter-wave radar equipment used for tunnel deformation monitoring.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention, by setting up an auxiliary mechanism, allows millimeter-wave radar equipment to be maintained without relying on scaffolding or aerial work platforms for high-altitude operations. This not only shortens maintenance time and improves work efficiency, but also avoids the costs associated with scaffolding materials, work platform rentals, and additional labor, thereby effectively reducing resource waste and improving the effectiveness of millimeter-wave radar equipment used for tunnel deformation monitoring. When the radar body needs to be installed directly below the monitoring point on the tunnel arch, the radar body can be installed on top of the sliding plate using another auxiliary hole. Then, using the controller, motor, support frame, mounting column, and rectangular plate, the round rod can be rotated between the two perforated seats. Next, using the rotating round rod, two cylindrical holes, two winding wheels, two wire ropes, and two cylindrical blocks, the sliding plate can be moved vertically upward inside the chute. Finally, using the vertically moving sliding plate, the radar body can be moved vertically upward.

[0020] 2. When the radar body reaches its maximum position, the controller, electric push rod, rectangular block, U-shaped frame, and mounting block work together to drive the electromagnet to move horizontally. Then, the controller, motor, support frame, perforated seat, and round rod work together to drive both winding wheels to unwind. Next, the two unwinding winding wheels, two wire ropes, two cylindrical holes, two auxiliary slots, two cylindrical blocks, the starting electromagnet, the starting electric push rod, the iron plate, one of the auxiliary holes, the sliding plate, the U-shaped frame, the rectangular block, and the mounting block work together to drive the radar body to move horizontally. When the radar body reaches its maximum position, the controller can be used to shut off the motor and electric push rod. At this point, the stopped radar body is directly below the monitoring point on the tunnel arch, completing the installation of the radar body. To remove the installed radar body, simply reverse the above steps.

[0021] 3. By setting up a protective mechanism, the present invention can protect the controller and another auxiliary hole to avoid accidental contact. When the controller needs to be used, the cover can be opened directly by using the hand-tightening bolt, and the controller can be used at this time. When the controller is finished, the hand-tightening bolt can be returned to its original position.

[0022] 4. In use, the power supply module provides the required power to each functional module; the signal transmission module generates and transmits millimeter-wave signals that meet the detection requirements; the signal receiving module receives electromagnetic wave signals and converts them into electrical signals that can be processed by subsequent modules; the signal conditioning module preprocesses the received signals to prepare for subsequent digital processing; the analog-to-digital conversion module converts the preprocessed signals into digital signals for subsequent processing; the digital signal processing module performs in-depth analysis and feature extraction on the digital signals, converting them into target information; the data fusion module integrates, analyzes, and optimizes the processed signal data; the output module outputs the integrated signal data in a form recognizable by the external system to enable data interaction between the radar and external devices; and the control module coordinates the orderly operation of each module to ensure that the radar completes the detection task stably and efficiently.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figures 1-9 As shown, the present invention provides a technical solution: a millimeter-wave radar device for monitoring tunnel deformation, including a radar body 1, and an auxiliary mechanism 2 disposed on the outside of the radar body 1;

[0036] The auxiliary mechanism 2 includes a mounting column 201. A groove 202 is formed at the top of the mounting column 201, and two auxiliary holes 203 are formed on the inner wall of the groove 202. A support frame 204 and a controller 221 are mounted on the surface of the mounting column 201. A motor 205 is mounted on the top of the support frame 204. A rectangular plate 206 is mounted on the top of the mounting column 201, and two perforated seats 207 are mounted on the top of the rectangular plate 206. A round rod 208 is mounted on the output end of the motor 205, and two coils are fixedly sleeved on the outer surface of the round rod 208. The bottom of the wheel 209 and the rectangular plate 206 has two cylindrical holes 210 and two auxiliary grooves 211. Each winding wheel 209 has a steel wire rope 212 wound inside. A sliding plate 213 is slidably connected inside the sliding groove 202. An iron sheet 215 is fixedly embedded on the surface of the sliding plate 213. Two cylindrical blocks 214 are fixed to the top of the sliding plate 213. A U-shaped frame 216 is fixed to the surface of the mounting column 201. A rectangular block 217 is fixed inside the U-shaped frame 216. An electric push rod 218 is mounted on the front surface of the rectangular block 217. An installation block 219 is installed at one end of the telescopic end of the electric push rod 218. An electromagnet 220 is installed on the surface of the installation block 219. The interior of one of the auxiliary holes 203 is connected to the interior of the U-shaped frame 216, and the bottom of the inner wall of one of the auxiliary holes 203 is on the same plane as the bottom of the inner wall of the U-shaped frame 216. Each wire rope 212 is adapted to each auxiliary groove 211. The motor 205 is electrically connected to the controller 221. The round rod 208 is rotatably sleeved between the interiors of two perforated seats 207. The interior of each cylindrical hole 210 is connected to the interior of each auxiliary groove 211. One end of each wire rope 212 is movably sleeved inside each cylindrical hole 210. One end of each wire rope 212 is fixed to the top of each cylindrical block 214. The electric push rod 218 is electrically connected to the controller 221. One end of the telescopic end of the electric push rod 218 movably passes through the front surface of the rectangular block 217. The telescopic electromagnet 220 is electrically connected to the controller 221. The bottom of the radar body 1 is installed with the top of the slide plate 213.

[0037] In this embodiment, when the radar body 1 needs to be installed directly below the monitoring point on the tunnel arch, the controller 221 is first connected to an external power supply. Then, the mounting post 201 is installed in a suitable position inside the tunnel. Next, using the auxiliary hole 203, the radar body 1 is installed on top of the slide plate 213. Then, the controller 221 starts the motor 205. The started motor 205, in conjunction with the support frame 204, the mounting post 201, and the rectangular plate 206, drives the round rod 208 to rotate between the two perforated seats 207. The rotating round rod 208 drives both winding wheels 209 to rotate. Simultaneously, both rotating winding wheels 209, in conjunction with their corresponding cylindrical holes 210, cause the corresponding... Both steel wire ropes 212 are wound up, and the two wound steel wire ropes 212, in cooperation with the corresponding cylindrical blocks 214 and slides 202, drive the slide plate 213 to move vertically upward. At the same time, the vertically moving slide plate 213 will drive the radar body 1 and the iron plate 215 to move vertically upward. When the radar body 1 moves vertically upward to the point where it can no longer move, the tops of the two cylindrical blocks 214 are in contact with the bottom of the rectangular plate 206. At the same time, the controller 221 will directly shut off the motor 205. The shut-off motor 205 will stop the radar body 1 from moving vertically upward. Then, the controller 221 will activate the electromagnet 220 and the electric push rod 218. The activated electric push rod 218 will then move vertically upward at the rectangular block 217 and the U-shaped plate 206. With the cooperation of the frame 216, the mounting block 219 is driven to move horizontally. The horizontal movement of the mounting block 219 will drive the electromagnet 220 to move horizontally. When the electromagnet 220 moves to its limit, it will attract the slide plate 213 with the cooperation of the iron plate 215. At the same time, the controller 221 will directly shut off the electric push rod 218. The shut-off electric push rod 218 will stop the electromagnet 220 from moving horizontally. Then, the controller 221 will start the electric push rod 218 and the motor 205. The started motor 205, with the cooperation of the above-mentioned components, will cause both steel wire ropes 212 to unwind. At the same time, the started electric push rod 218 will move along the rectangular block 217, the U-shaped frame 216, and the mounting block. 219. The activation electromagnet 220, iron plate 215, two unwinding steel wire ropes 212, two cylindrical holes 210, two auxiliary grooves 211, two cylindrical blocks 214, and one of the auxiliary holes 203 work together to drive the slide plate 213 to move horizontally. The horizontally moving slide plate 213, in turn, drives the radar body 1 to move horizontally. When the radar body 1 can no longer move, the controller 221 will directly shut off the electric push rod 218 and the motor 205. Simultaneously, the stopped radar body 1 will be directly below the monitoring point on the tunnel arch, thus completing the installation of the radar body 1. When it is necessary to remove the installed radar body 1, simply reverse the above steps to reset the radar body 1.Once the radar body 1 is reset to its original position, it can then be removed from the slide plate 213 using the assistance of another auxiliary hole 203.

[0038] Example 2: According to Figures 1-3 , Figure 5 , Figure 7 and Figure 8 As shown, the auxiliary mechanism 2 is provided with a protective mechanism 3. The protective mechanism 3 includes a housing 301. A cover 302 is rotatably connected to the corner of the front surface of the housing 301. A hand-tightening bolt 303 is threaded through the front surface of the cover 302. The housing 301 is fixed to the surface of the mounting post 201. The threaded end of the hand-tightening bolt 303 is threadedly connected to the front surface of the housing 301. The controller 221 is located inside the housing 301. The outlet of another auxiliary hole 203 is located inside the housing 301.

[0039] In this embodiment, when the controller 221 is needed, first loosen the hand-tightening bolt 303, then apply a force to the cover 302, causing the cover 302 to rotate around the corner of the front surface of the housing 301 until the cover 302 rotates to a suitable angle. Then the controller 221 can be used. When the controller 221 is finished, simply reverse the above operation steps until the hand-tightening bolt 303 is reset to its original position.

[0040] Example 3: According to Figure 10 As shown, the system includes a power supply module 4, a signal transmission module 5, a signal receiving module 6, a signal processing unit 7, and a control module 8. The signal processing unit 7 includes a signal conditioning module 701, an analog-to-digital converter module 702, a digital signal processing module 703, a data fusion module 704, and an output module 705. The power supply module 4 provides stable power to each module. The signal transmission module 5 generates and transmits millimeter-wave signals that meet the detection requirements. The signal receiving module 6 receives the captured echo signals. The signal conditioning module 701 preprocesses the received electrical signals to prepare for subsequent digital processing. The analog-to-digital converter module 702 converts the preprocessed signals into digital signals for subsequent digital processing. The digital signal processing module 703 performs algorithm-level processing on the digitized signals to extract key features. The data fusion module 704 integrates the processed signal data. The output module 705 outputs the integrated parameters in a standardized format. The control module 8 ensures that each component operates according to the logical timing sequence, avoids interference between modules, and ensures the reliability of the radar.

[0041] In this embodiment, during use, the power supply module 4 provides the required power support to each functional module, the signal transmission module 5 generates and transmits millimeter-wave signals that meet the detection requirements, the signal receiving module 6 receives electromagnetic wave signals and converts them into electrical signals that can be processed by subsequent modules, the signal conditioning module 701 preprocesses the received signals to provide high-quality analog signals for subsequent digitization and algorithm analysis, the analog-to-digital conversion module 702 converts the preprocessed signals into digital signals for subsequent processing, the digital signal processing module 703 performs in-depth analysis and feature extraction on the digital signals and converts them into target information, the data fusion module 704 integrates, analyzes and optimizes the processed signal data, the output module 705 outputs the integrated signal data in a form that can be recognized by the external system to realize data interaction between the radar body 1 and external devices, and the control module 8 coordinates the orderly operation of each module to ensure that the radar body 1 completes the detection task stably and efficiently.

[0042] The overall effect and working principle of the mechanism are as follows:

[0043] During installation and maintenance, when the radar body 1 needs to be installed directly below the monitoring point on the tunnel arch, first connect the controller 221 to the external power supply. Then, install the mounting post 201 in a suitable position inside the tunnel. Next, using the assistance of another auxiliary hole 203, install the radar body 1 on top of the slide plate 213. Then, use the controller 221 to start the motor 205. At this time, the started motor 205, with the cooperation of the support frame 204, the mounting post 201, and the rectangular plate 206, drives the round rod 208 to rotate between the two perforated seats 207. The rotating round rod 208 drives both winding wheels 209 to rotate. At the same time, both rotating winding wheels 209 are engaged with the corresponding cylindrical holes 210. This causes the corresponding wire ropes 212 to be wound up. Both wound wire ropes 212, in cooperation with their corresponding cylindrical blocks 214 and slides 202, drive the slide plate 213 to move vertically upwards. Simultaneously, the vertically moving slide plate 213 drives the radar body 1 and the iron plate 215 to move vertically upwards as well. When the radar body 1 reaches its maximum vertical position, the tops of the two cylindrical blocks 214 contact the bottom of the rectangular plate 206. At this point, the controller 221 directly shuts off the motor 205. The shut-off motor 205 stops the radar body 1 from moving vertically upwards. Then, the controller 221 activates the electromagnet 220 and the electric push rod 218. The activated electric push rod 218 then... With the cooperation of rectangular block 217 and U-shaped frame 216, mounting block 219 moves horizontally. This horizontal movement of mounting block 219 causes electromagnet 220 to move horizontally as well. When electromagnet 220 can no longer move, it, in cooperation with iron plate 215, attracts slide plate 213. Simultaneously, controller 221 directly shuts off electric push rod 218, causing electromagnet 220 to stop moving horizontally. Then, controller 221 activates electric push rod 218 and motor 205. The activated motor 205, in cooperation with the aforementioned components, causes both wire ropes 212 to unwind. Simultaneously, the activated electric push rod 218, along with rectangular block 217... The U-shaped frame 216, mounting block 219, starting electromagnet 220, iron plate 215, two unwinding steel wire ropes 212, two cylindrical holes 210, two auxiliary slots 211, two cylindrical blocks 214, and one of the auxiliary holes 203 work together to drive the sliding plate 213 to move horizontally. The horizontally moving sliding plate 213 then drives the radar body 1 to move horizontally as well. When the radar body 1 can no longer move, the controller 221 will directly shut off the electric push rod 218 and the motor 205. Simultaneously, the stopped radar body 1 will be directly below the monitoring point on the tunnel arch, thus completing the installation of the radar body 1. To remove the installed radar body 1, simply reverse the above steps.This causes the radar body 1 to move and reset until it returns to its original position. Then, using the assistance of another auxiliary hole 203, the radar body 1 can be removed from the slide plate 213.

[0044] During the protection phase, when the controller 221 needs to be used, first loosen the hand-tightening bolt 303, then apply a force to the cover 302, causing the cover 302 to rotate around the corner of the front surface of the housing 301 as the center, until the cover 302 rotates to the appropriate angle, and then the controller 221 can be used. When the controller 221 is finished, simply reverse the above operation steps until the hand-tightening bolt 303 is reset to its original position.

[0045] During operation, the power supply module 4 provides the required power to each functional module; the signal transmission module 5 generates and transmits millimeter-wave signals that meet the detection requirements; the signal receiving module 6 receives electromagnetic wave signals and converts them into electrical signals that can be processed by subsequent modules; the signal conditioning module 701 preprocesses the received signals to provide high-quality analog signals for subsequent digitization and algorithm analysis; the analog-to-digital conversion module 702 converts the preprocessed signals into digital signals for subsequent processing; the digital signal processing module 703 performs in-depth analysis and feature extraction on the digital signals, converting them into target information; the data fusion module 704 integrates, analyzes, and optimizes the processed signal data; the output module 705 outputs the integrated signal data in a form recognizable by external systems to enable data interaction between the radar body 1 and external devices; and the control module 8 coordinates the orderly operation of each module to ensure that the radar body 1 completes the detection task stably and efficiently.

[0046] Among them, the controller 221 (PLC controller), motor 205, electric push rod 218 and radar body 1 are all existing technologies, and their working principles are all publicly available technologies. Their models can be selected according to the actual situation, and will not be explained in detail here.
