Description

Technical Field

[0001] This invention relates to the field of highway traffic condition monitoring and early warning technology, and in particular to a highway traffic condition monitoring and early warning device and method. Background Technology

[0002] The fundamental purpose of highway traffic condition monitoring and early warning is to build a proactive safety and efficient management system that "prevents problems before they occur." Its goal is not just monitoring and warning, but to protect lives and infrastructure safety, improve traffic efficiency and economic benefits, and support scientific management and long-term development through proactive perception, intelligent analysis and early intervention.

[0003] Existing highway traffic monitoring and early warning devices monitor road conditions using laser remote sensing road condition sensors. These sensors are typically installed at a height of 3-4 meters. During use, they require frequent maintenance and cleaning. The installation height necessitates the use of ladders for workers to ascend, posing a safety hazard. Furthermore, the low altitude makes maintenance and cleaning of the laser remote sensing road condition sensors inconvenient and can negatively impact the effectiveness of these processes. This leads to issues with monitoring accuracy and ultimately reduces the overall value of the traffic monitoring and early warning device. Summary of the Invention

[0004] This invention discloses a highway road condition monitoring and early warning device, aiming to solve the technical problem that existing highway road condition monitoring and early warning devices monitor road conditions using laser remote sensing road condition sensors. These sensors are typically installed at a height of 3-4 meters. During use, they require frequent maintenance and cleaning. The installation height requires workers to use ladders to ascend, posing certain safety hazards. At the same time, it is inconvenient for workers to maintain and clean the laser remote sensing road condition sensors at low altitudes, which to some extent affects the maintenance and cleaning effect, resulting in technical problems such as monitoring accuracy issues during use.

[0006] In a preferred embodiment, a scraper is fixedly connected to the bottom of the lifting slide, and an installation groove is opened at the bottom of the lifting slide near the scraper. An air plate is fixedly connected inside the installation groove, and an air compressor is fixedly connected to the top of the air plate. The air supply end of the air compressor is connected to the inside of the air plate through a pipe. Air jet holes are opened at equal intervals at the bottom of the air plate, and an air inlet pipe is fixedly connected to the air inlet end of the air compressor. The opening end of the air inlet pipe is located outside the lifting slide, and a guide vane is fixedly connected to the inner side wall of the lifting slide near the bottom.

[0007] In a preferred embodiment, a positioning slide rod is fixedly connected to the top of the base, and the same connecting ring frame is fixedly connected to both sides of the lifting slide, with the connecting ring frame slidably connected to the positioning slide rod.

[0008] In a preferred embodiment, a top seat is fixedly connected to the top of the mounting rod, and an upper lifting rod is fixedly connected to the top of the top seat, with a rainproof mechanism provided at the end of the upper lifting rod.

[0009] In a preferred embodiment, the rainproof mechanism includes a rainproof plate, which is fixedly connected to the end of the lifting rod. The rainproof plate has through drainage holes on its arc surface. The outer side wall of the rainproof plate is connected to unfolding pieces at equal intervals by hinges. Each unfolding piece is fixedly connected to an unfolding spring at equal intervals. One end of the unfolding spring is fixedly connected to the downward-facing arc surface of the rainproof plate.

[0010] In a preferred embodiment, a connecting rod is fixedly connected to the top of the connecting ring frame, and a shock-absorbing connecting mechanism is provided above the connecting rod. The shock-absorbing connecting mechanism includes a mounting ring rod, an inner connecting rod is fixedly connected to the inner ring surface of the mounting ring rod, a connecting cylinder is fixedly connected to one end of the inner connecting rod, the connecting cylinder is slidably connected to the positioning slide rod, and the mounting ring rod is fixedly connected to the top of the connecting rod.

[0011] In a preferred embodiment, the laser remote sensing road condition sensor body is fixedly connected to a frame at the bottom above the mounting ring rod, and the frame and the mounting ring rod have overlapping connection holes, with a connecting rod inserted into the interior of each connection hole.

[0012] In a preferred embodiment, the mounting ring rod is fixedly connected to two symmetrically distributed locking brackets at its bottom below the connecting rod, and each locking bracket is fixedly connected to a slide cylinder at its top. A shock-absorbing spring rod is fixedly connected to the bottom inner wall of the slide cylinder, and a pressing head is fixedly connected to the top of the shock-absorbing spring rod.

[0013] In a preferred embodiment, the bottom of the connecting rod has a placement groove, and the inner walls on both sides of the placement groove have limit grooves. A connecting slider is slidably connected inside the two limit grooves. A sliding block is fixedly connected to each of the two connecting sliders. A swing rod is fixedly connected to the bottom of the sliding block. The sliding block is adapted to the positioning frame. An upper frame is fixedly connected to the top of the connecting rod. The bottom of the upper frame, located above the pressing head, has a matching connecting groove, and the pressing head is inserted into the connecting groove.

[0014] A method for monitoring and warning highway traffic conditions, using a highway traffic condition monitoring and warning device as described above, includes the following steps: Step 1: When installing the laser remote sensing road condition sensor body, align the connecting holes on the frame and the mounting ring rod, then insert the connecting rod into the connecting hole, align the pressing head with the connecting groove, and during the insertion of the connecting rod, the pressing head will squeeze the shock-absorbing spring rod. When the connecting rod is inserted to the bottom, move the sliding block out by the swing rod, so that the sliding block is locked into the mounting bracket, thus completing the fixing of the connecting rod. Step 2: After the laser remote sensing road condition sensor body is installed, move it to the top. During the operation of the laser remote sensing road condition sensor body, the rainproof plate plays a role in shielding and guiding the rainwater above it, reducing the interference caused by the rainwater. At the same time, if the rainfall is heavy, the rainwater impacts the unfolding plate, causing the unfolding spring to be passively compressed and the unfolding plate to deflect downward. The unfolding plate and the rainproof plate work together to increase the shielding space above the laser remote sensing road condition sensor body, thereby improving the rainproof effect. Step 3: When cleaning and maintaining the laser remote sensing road condition sensor body, the operator pulls the docking rod out of the limiting cylinder using the pull rod. After the pull rod is completely removed from the protective frame, press it down so that the pull rod is in a vertical downward position. The operator then pulls the lower lever using the hand lever to pull down the upper accumulation ring to the docking ring. The operator releases the restriction on the pull rod, and the positioning spring rod drives the docking rod through the docking hole on the accumulation ring and inserts it into the limiting cylinder, completing the descent of the laser remote sensing road condition sensor body. The operator then performs maintenance and cleaning. After maintenance and cleaning, the pull rod is completely removed from the protective frame again. The operator then pushes the lower lever up, and the lower accumulation ring moves back into the docking ring. The docking rod resets, and the operation ends.

[0015] As can be seen from the above, the highway road condition monitoring and early warning device provided by the present invention has the following advantages: When cleaning and maintaining the laser remote sensing road condition sensor body, the operator pulls the docking rod out of the limiting cylinder using a pull rod. After the pull rod is completely removed from the protective frame, it is pressed down to make the pull rod vertically downward. The operator then pulls the pull rod with a hand lever to pull down the upper accumulation ring to the docking ring. The operator releases the restriction on the pull rod, and the positioning spring rod drives the docking rod to pass through the docking hole on the accumulation ring and insert into the limiting cylinder, completing the descent of the laser remote sensing road condition sensor body. The height of the pull rod is about 1.5 meters, which allows the operator to easily perform manual operation. At the same time, after the laser remote sensing road condition sensor body is lowered, it is in a stable positioning state, which facilitates the operator to clean and maintain it, improving the cleaning and maintenance effect. This manual lifting method avoids the accidental risks of mechanical lifting, and the operator does not need to climb, eliminating safety hazards and providing convenient and quick operation.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] The highway traffic condition monitoring and early warning device disclosed in this invention is mainly applied to existing highway traffic condition monitoring and early warning devices. These devices monitor road conditions using laser remote sensing road condition sensors, which are typically installed at a height of 3-4 meters. During use, they require frequent maintenance and cleaning. The installation height necessitates the use of ladders for workers to ascend, posing a safety hazard. Furthermore, the low altitude makes maintenance and cleaning of the laser remote sensing road condition sensors inconvenient, potentially affecting the effectiveness of these processes and leading to scenarios where monitoring accuracy is compromised during use.

[0029] Reference Figures 1-10 A highway road condition monitoring and early warning device includes a base 1 and a laser remote sensing road condition sensor body 9. A mounting rod 2 is fixedly connected to the top of the base 1, and a lifting groove 5 is formed on the mounting rod 2. A manual lifting mechanism 3 is provided at the lifting groove 5. The manual lifting mechanism 3 includes a lifting carriage 306, which is slidably connected to the lifting groove 5. A contact sensor 304 is fixedly connected to the top inner wall of the lifting groove 5. A trigger rod 305 is fixedly connected to the top of the lifting carriage 306. A pull-down rod 301 is fixedly connected to the bottom of the lifting carriage 306. A hand lever 303 is fixedly connected to the outer wall of the pull-down rod 301 near its bottom end. Two accumulation rings 307 are fixedly connected to the outer wall of the pull-down rod 301. Each of the two accumulation rings 307 has a mating hole 308. Two external rods 318 are fixedly connected to the outer wall of the mounting rod 2, and the two external rods 318 are positioned opposite each other. A single docking ring 316 is fixedly connected to the outer wall of the docking ring 316. Two connecting blocks 315 are fixedly connected to the outer wall of the docking ring 316. A single protective frame 302 is fixedly connected to the opposite side of the two connecting blocks 315. Both sides of the protective frame 302 have through holes 320. A limiting cylinder 319 is fixedly connected to the inner wall of the docking ring 316. A docking rod 317 is inserted into the inside of the limiting cylinder 319. The docking rod 317 passes through one of the through holes 320. A shaft bracket 324 is fixedly connected to the end of the docking rod 317 away from the limiting cylinder 319. The same pull rod 321 is connected to the inner walls of both sides of the shaft bracket 324 through bearings. End blocks 323 are fixedly connected to both sides of the docking rod 317 located on the shaft bracket 324. Positioning spring rods 322 are fixedly connected to the side of the two end blocks 323 facing the limiting cylinder 319. One end of each positioning spring rod 322 is fixedly connected to the inner wall of one side of the protective frame 302.

[0030] In specific application scenarios, when cleaning and maintaining the laser remote sensing road condition sensor body 9, the operator pulls the docking rod 317 out of the limiting cylinder 319 using the pull rod 321. After the pull rod 321 is completely removed from the protective frame 302, it is pressed down to make the pull rod 321 vertically downward. The operator then pulls the pull rod 301 using the lever 303, pulling down the upper accumulation ring 307 to the docking ring 316. When the operator releases the restriction on the pull rod 321, the positioning spring rod 322 drives the docking... The insertion rod 317 passes through the docking hole 308 on the accumulation ring 307 and is inserted into the limiting cylinder 319, completing the descent of the laser remote sensing road condition sensor body 9. The pull rod 301 is about 1.5 meters high, which allows the operator to easily operate it manually. At the same time, after the laser remote sensing road condition sensor body 9 is lowered, it is in a stable positioning state, which makes it convenient for the operator to clean and maintain it, improving the cleaning and maintenance effect. This manual lifting method avoids the accidental risks of mechanical lifting, and the operator does not need to climb, eliminating safety hazards and making the operation convenient and quick.

[0031] Specifically, when the operator pulls down the pull rod 301, the trigger rod 305 separates from the contact sensor 304, and the back-end control terminal controls the air compressor 314 to start. When the lifting slide 306 slides in the lifting slide 5, the scraper 309 scrapes off the garbage accumulated in the lifting slide 5. The air compressor 314 draws outside air into the air plate 310 through the air intake pipe 313 and sprays it out through the jet hole 312 to accelerate the separation of garbage and prevent the lifting slide 306 from being blocked when it slides down due to the docking of garbage, thus ensuring that the lifting slide 306 can slide down smoothly.

[0032] Reference Figures 1-7 In a preferred embodiment, a scraper 309 is fixedly connected to the bottom of the lifting slide 306, and an installation groove 311 is opened at the bottom of the lifting slide 306 near the scraper 309. An air plate 310 is fixedly connected inside the installation groove 311, and an air compressor 314 is fixedly connected to the top of the air plate 310. The air supply end of the air compressor 314 is connected to the inside of the air plate 310 through a pipe. Air jet holes 312 are opened at equal intervals at the bottom of the air plate 310. An air inlet pipe 313 is fixedly connected to the air inlet end of the air compressor 314. The opening end of the air inlet pipe 313 is located outside the lifting slide 306. A guide vane 4 is fixedly connected to the inner side wall of the lifting slide 5 near the bottom.

[0033] Reference Figure 1 and Figure 2 In a preferred embodiment, a positioning slide rod 6 is fixedly connected to the top of the base 1, and the same connecting ring frame 12 is fixedly connected to both sides of the lifting slide 306, with the connecting ring frame 12 slidably connected to the positioning slide rod 6.

[0034] Reference Figure 1 , Figure 2 and Figure 10 In a preferred embodiment, a top seat 7 is fixedly connected to the top of the mounting rod 2, and an upper lifting rod 10 is fixedly connected to the top of the top seat 7. The end of the upper lifting rod 10 is provided with a rainproof mechanism 8.

[0035] Specifically, during the operation of the laser remote sensing road condition sensor body 9, the rainproof plate 801 serves to shield and guide the rainwater above it, reducing the interference caused by the rainwater. At the same time, if the rainfall is heavy, the rainwater impacts the unfolding plate 802, causing the unfolding spring 804 to be passively compressed and the unfolding plate 802 to deflect downwards. The unfolding plate 802 and the rainproof plate 801 work together to increase the shielding space above the laser remote sensing road condition sensor body 9, further improving the rainproof effect.

[0036] Reference Figure 2 and Figure 10 In a preferred embodiment, the rainproof mechanism 8 includes a rainproof plate 801, which is fixedly connected to the end of the lifting rod 10. The rainproof plate 801 has through drainage holes 803 on its arc surface. The outer side wall of the rainproof plate 801 is connected to unfolding pieces 802 at equal intervals by hinges. Each unfolding piece 802 is fixedly connected to an unfolding spring 804 at equal intervals. One end of the unfolding spring 804 is fixedly connected to the downward-facing arc surface of the rainproof plate 801.

[0037] Reference Figure 1 , Figure 4 and Figure 8 In a preferred embodiment, a connecting rod 11 is fixedly connected to the top of the connecting ring frame 12, and a shock-absorbing connecting mechanism 13 is provided above the connecting rod 11. The shock-absorbing connecting mechanism 13 includes a mounting ring rod 1301, an inner connecting rod 1302 is fixedly connected to the inner ring surface of the mounting ring rod 1301, a connecting cylinder 1303 is fixedly connected to one end of the inner connecting rod 1302, the connecting cylinder 1303 is slidably connected to the positioning slide rod 6, and the mounting ring rod 1301 is fixedly connected to the top of the connecting rod 11.

[0038] Reference Figure 8 and Figure 9 In a preferred embodiment, the laser remote sensing road condition sensor body 9 is fixedly connected to the frame 14 at the bottom above the mounting ring rod 1301, and the frame 14 and the mounting ring rod 1301 have overlapping connection holes, and a connecting rod 1305 is inserted into the interior of each connection hole.

[0039] Reference Figure 8 and Figure 9In a preferred embodiment, the bottom of the mounting ring rod 1301 located below the connecting rod 1305 is fixedly connected to two symmetrically distributed positioning brackets 1308, and the top of each positioning bracket 1308 is fixedly connected to a slide cylinder 1313. The bottom inner wall of the slide cylinder 1313 is fixedly connected to a shock-absorbing spring rod 1307, and the top of the shock-absorbing spring rod 1307 is fixedly connected to a pressing head 1314.

[0040] Specifically, during the installation of the laser remote sensing road condition sensor body 9, the frame 14 is aligned with the connecting hole on the mounting ring rod 1301. Then, the connecting rod 1305 is inserted into the connecting hole, and the pressing head 1314 is aligned with the connecting groove 1306. During the insertion of the connecting rod 1305, the pressing head 1314 compresses the shock-absorbing spring rod 1307. When the connecting rod 1305 is inserted to the bottom, the sliding block 1309 is moved out by the swing rod 1312, so that the sliding block 1309 is locked into the mounting bracket 1308, thus fixing the connecting rod 1305. At this time, the shock-absorbing spring rod 1307 is in a state of extreme compression, which reduces the wind impact on the laser remote sensing road condition sensor body 9 during operation, thereby improving the stability of the laser remote sensing road condition sensor body 9 during operation and improving the accuracy of road condition monitoring results.

[0041] Reference Figure 8 and Figure 9 In a preferred embodiment, the bottom of the connecting rod 1305 has a placement groove, and the inner walls on both sides of the placement groove have limiting grooves 1310. The interior of the two limiting grooves 1310 is slidably connected to the connecting sliders 1311. The two connecting sliders 1311 are fixedly connected to the sliding blocks 1309. The bottom of the sliding blocks 1309 is fixedly connected to the swing rod 1312. The sliding blocks 1309 are adapted to the positioning frame 1308. The top of the connecting rod 1305 is fixedly connected to the upper frame 1304. The bottom of the upper frame 1304, located above the pressing head 1314, has a matching connecting groove 1306. The pressing head 1314 is inserted into the connecting groove 1306.

[0042] A method for monitoring and warning highway traffic conditions, using a highway traffic condition monitoring and warning device as described above, includes the following steps: Step 1: When installing the laser remote sensing road condition sensor body 9, align the frame 14 with the connecting hole on the mounting ring rod 1301, then insert the connecting rod 1305 into the connecting hole, align the pressing head 1314 with the connecting groove 1306, and during the insertion of the connecting rod 1305, the pressing head 1314 presses the shock-absorbing spring rod 1307. When the connecting rod 1305 is inserted to the bottom, the sliding block 1309 is moved out by the swing rod 1312, so that the sliding block 1309 is locked into the mounting bracket 1308, thus completing the fixing of the connecting rod 1305. Step 2: After the laser remote sensing road condition sensor body 9 is installed, move it to the top. During the operation of the laser remote sensing road condition sensor body 9, the rainproof plate 801 acts as a shield and guide for the rainwater above it, reducing the interference caused by the rainwater. At the same time, if the rainfall is heavy, the rainwater impacts the unfolding plate 802, causing the unfolding spring 804 to be passively compressed and the unfolding plate 802 to deflect downward. The unfolding plate 802 and the rainproof plate 801 work together to increase the shielding space above the laser remote sensing road condition sensor body 9, thereby improving the rainproof effect. Step 3: When cleaning and maintaining the laser remote sensing road condition sensor body 9, the operator pulls the docking rod 317 out of the limiting cylinder 319 using the pull rod 321. After the pull rod 321 is completely removed from the protective frame 302, it is pressed down so that the pull rod 321 is in a downward vertical position. The operator then pulls the pull rod 301 using the lever 303 to pull down the upper accumulation ring 307 to the docking ring 316. The operator then releases the restriction on the pull rod 321. Then, the positioning spring rod 322 drives the docking rod 317 through the docking hole 308 on the accumulation ring 307 and inserts it into the limiting cylinder 319, completing the descent of the laser remote sensing road condition sensor body 9. The operator then performs maintenance and cleaning on it. After maintenance and cleaning, the pull rod 321 is completely removed from the protective frame 302 again. The operator then pushes the pull rod 301 up, and the accumulation ring 307 located below moves back into the docking ring 316. The docking rod 317 is reset, and the operation ends.

[0043] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

10. A method for monitoring and warning highway traffic conditions, using a highway traffic condition monitoring and warning device as described in claim 9, characterized in that, Includes the following steps: Step 1: When installing the laser remote sensing road condition sensor body (9), align the connecting hole on the frame (14) with the mounting ring rod (1301), then insert the connecting rod (1305) into the connecting hole, align the pressing head (1314) with the connecting groove (1306), and during the insertion of the connecting rod (1305), the pressing head (1314) presses the shock-absorbing spring rod (1307). When the connecting rod (1305) is inserted to the bottom, the sliding block (1309) is moved out by the swing rod (1312), so that the sliding block (1309) is locked into the mounting bracket (1308), thus completing the fixing of the connecting rod (1305). Step 2: After the laser remote sensing road condition sensor body (9) is installed, move it to the top. During the operation of the laser remote sensing road condition sensor body (9), the rainproof plate (801) plays a role in shielding and guiding the rainwater above it, reducing the interference caused by the rainwater. At the same time, if the rainfall is large, the rainwater will impact the unfolding plate (802), causing the unfolding spring (804) to be passively compressed. The unfolding plate (802) will deflect downwards. The unfolding plate (802) and the rainproof plate (801) work together to increase the shielding space above the laser remote sensing road condition sensor body (9) and improve the rainproof effect. Step 3: When cleaning and maintaining the laser remote sensing road condition sensor body (9), the operator pulls the docking rod (317) out of the limiting cylinder (319) using the pull rod (321). After the pull rod (321) is completely removed from the protective frame (302), press it down so that the pull rod (321) is in a vertical downward position. The operator pulls the pull rod (301) down using the lever (303) to pull the upper accumulation ring (307) down to the docking ring (316). The operator then releases the restriction on the pull rod (321). Then the positioning spring rod (322) drives the docking rod (317) through the docking hole (308) on the accumulation ring (307) and inserts it into the limiting cylinder (319), completing the descent of the laser remote sensing road condition sensor body (9). The operator performs maintenance and cleaning on it. After maintenance and cleaning, the pull rod (321) is completely removed from the protective frame (302). The operator pushes the pull rod (301) up, and the accumulation ring (307) located below moves back into the docking ring (316). The docking rod (317) is reset, and the operation ends.
