Description

Technical Field

[0001] This invention relates to the field of traffic environment monitoring technology, specifically to an intelligent safety monitoring device and system for highways. Background Technology

[0002] Intelligent safety monitoring technology for highways utilizes IoT sensors, high-definition visual monitoring, meteorological monitoring stations, and millimeter-wave radar, combined with big data analysis and artificial intelligence algorithms, to achieve real-time perception and early warning of road conditions, traffic flow dynamics, and environmental risks. Monitoring of snow accumulation and icing on roads is particularly crucial. Snow reduces the road surface friction coefficient, while icing (especially "black ice") causes tire adhesion to drop by more than 80%, leading to vehicle loss of control, skidding, and significantly increased braking distances, greatly increasing the risk of multi-vehicle pileups and other serious accidents.

[0003] In existing technologies, although intelligent safety monitoring solutions for highways can directly detect snow or ice accumulation on the ground using temperature sensors, distance sensors, and monitoring probes, these solutions have significant limitations. In particular, after installation, they can only monitor fixed locations, resulting in unreliable and ineffective monitoring results, especially regarding the lack of accurate assessment of the friction capacity of the icy road surface. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a safety intelligent monitoring device and monitoring system for highways to solve the problems mentioned in the background. This invention can detect snow accumulation on the ground over a large area, expand the monitoring range, and simultaneously acquire the friction force of the highway surface within the same range while monitoring snow accumulation, thus obtaining more detailed information on snow accumulation and icing on the road surface.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a safety intelligent monitoring device for highways, comprising a monitoring device body, the monitoring device body including a cleaning chamber, a power chamber, a guide rail, and a monitoring component. The two ends of the guide rail are welded to the sides of the cleaning chamber and the power chamber, respectively. The bottoms of the cleaning chamber and the power chamber are bolted to one side of the highway surface. The bottom of the guide rail is open, and a strip-shaped hole is formed on the top surface of the guide rail. The monitoring component is inserted into the strip-shaped hole. The monitoring component includes a pressing mechanism and a transmission mechanism. The cleaning component is installed inside the cleaning chamber. A motor is bolted to the inside of the power chamber. A lead screw is inserted into the output end of the motor, passing through the inside of the monitoring component. A pressing wheel is provided at the bottom of the pressing mechanism, and the pressing wheel is used to press against the highway surface. The end of the lead screw is embedded in the inner wall of the cleaning chamber via a bearing.

[0006] Furthermore, the transmission mechanism includes a support frame, a sliding sleeve, and a threaded sleeve. The support frame includes a first support frame and a second support frame. A plug-in post is installed at the bottom end of the first support frame, and a transmission frame is integrally formed on the side of the plug-in post.

[0007] Furthermore, a sliding sleeve is provided in the middle of the first support frame, and a threaded sleeve is provided in the middle of the second support frame. Both the sliding sleeve and the threaded sleeve are sleeved on the surface of the lead screw, and a gap is provided between the inner wall of the sliding sleeve and the surface of the lead screw. The first support frame and the second support frame are both in the form of a "T" shape.

[0008] Furthermore, both the first support frame and the second support frame extend upward from the inside of the strip hole, and the top ends of both the first support frame and the second support frame press against the surface of the guide rail. A pressure module is installed at one end of the threaded sleeve, a transmission spring is welded to one side of the sliding sleeve, and the other end of the transmission spring is welded to the surface of the pressure module.

[0009] Furthermore, an extension arm is installed at the bottom of the transmission frame, and a ranging module is screwed to the end of the extension arm. A clamping plate is integrally formed at the bottom of the extension arm. The pressing mechanism includes a pressing wheel, a support plate, and a rotating plate. A sandwich layer is provided in the middle area of ​​the surface of the pressing wheel, and a stop bar is installed on the inner side of the sandwich layer.

[0010] Furthermore, the two ends of the pressing roller are connected to the end of the clamping plate by a shaft, a support plate is welded on the inner wall of the clamping plate, a lower hanging plate is integrally formed at the bottom of the support plate, and a rotating plate is hinged to the bottom end of the lower hanging plate.

[0011] Furthermore, the end of the rotating plate is provided with an inclined plate, which is used to be embedded into the interior of the interlayer. The inclined plate rests against the stop bar through its vertical surface portion, and the entire inclined plate is embedded vertically downward into the interior of the interlayer. The rotating plate rotates around the bottom end of the lower hanging plate through a hinge.

[0012] Furthermore, the bottom of the cleaning chamber is integrally formed with a base plate, one end of which has a groove. The cleaning assembly is installed inside the groove and includes a telescopic sleeve, a spring rod, a top plate, and a sponge pad.

[0016] This intelligent safety monitoring system for highways can detect snow accumulation on the ground over a large area, expanding the monitoring range. It can also simultaneously acquire the friction force of the highway surface within the same range while monitoring snow accumulation, ultimately obtaining more detailed information on snow accumulation and icing on that section of the road.

[0017] This intelligent safety monitoring device for highways presses the monitoring components at the bottom directly onto the ground, and the power equipment moves the monitoring components. The pressure module can indirectly determine the current slippage situation on the highway, thereby determining the icing status. This makes the final icing situation more reflective of the current road information and more reliable.

[0018] This intelligent safety monitoring device for highways presses directly onto the ground via a pressing mechanism at the bottom of the monitoring component. It automatically switches the contact position between the pressing mechanism and the ground during each cycle of movement, reducing wear caused by the constant sliding friction between the pressing wheel and the ground. Combined with a cleaning component, it can also perform targeted cleaning of the contact area of ​​the pressing wheel after each test, improving the reliability of subsequent tests.

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] Please see Figures 1 to 8The present invention provides the following technical solution: a safety intelligent monitoring device for highways, comprising a monitoring device body, the monitoring device body including a cleaning chamber 1, a power chamber 2, a guide rail 3 and a monitoring component 4, the two ends of the guide rail 3 being welded to the sides of the cleaning chamber 1 and the power chamber 2 respectively, the bottoms of the cleaning chamber 1 and the power chamber 2 being fixed to the road surface on one side of the highway by bolts, the bottom of the guide rail 3 being open, and a strip-shaped hole 11 being provided on the top surface of the guide rail 3, the monitoring component 4 being inserted inside the strip-shaped hole 11, the monitoring component 4 including a pressing mechanism 8 and a transmission mechanism 7, the cleaning component 12 being installed inside the cleaning chamber 1, the motor 5 being bolted inside the power chamber 2, the output end of the motor 5 being fitted with a lead screw 6, the lead screw 6 passing through the inside of the monitoring component 4, the bottom of the pressing mechanism 8 being provided with a pressing wheel 21, the pressing wheel 21 being used to press on the road surface of the highway, and the end of the lead screw 6 being embedded in the inner wall of the cleaning chamber 1 through a bearing. This intelligent monitoring device is used to monitor whether snow has accumulated on the highway surface, whether there is ice on the surface, and to determine the severity of the current icing.

[0030] In use, this invention involves bolting the cleaning chamber 1 and the power chamber 2 to the side of the highway. Periodically activating the motor 5 inside the power chamber 2 moves the monitoring component 4 at the bottom of the track along the track surface, thus detecting snow accumulation in the corresponding area of ​​the highway. Simultaneously, the motor 5 drives the pressing mechanism 8 on the surface of the monitoring component 4 to move along the road surface. The pressure module 32 installed inside the monitoring component 4 detects the friction between the pressing mechanism 8 and the road surface, thereby determining whether icing has occurred within the current testing area and using this as a basis to roughly assess the risk of skidding on the highway. After each test, the friction detection area on the surface of the pressing wheel 21 is cleaned specifically inside the cleaning chamber 1.

[0031] In this embodiment, the transmission mechanism 7 includes a support frame, a sliding sleeve 29, and a threaded sleeve 31. The support frame includes a first support frame 28 and a second support frame 30. A plug-in post 34 is installed at the bottom end of the first support frame 28, and a transmission frame 17 is integrally formed on the side of the plug-in post 34. The sliding sleeve 29 is provided in the middle of the first support frame 28, and the threaded sleeve 31 is provided in the middle of the second support frame 30. Both the sliding sleeve 29 and the threaded sleeve 31 are sleeved on the surface of the lead screw 6, and a gap is provided between the inner wall of the sliding sleeve 29 and the surface of the lead screw 6. The first support frame 28 and the second support frame 30 are both in a "T" shape. Both the first support frame 28 and the second support frame 30 extend upwards from the inside of the strip hole 11, and the top ends of both the first support frame 28 and the second support frame 30 press against the surface of the guide rail 3. A pressure module 32 is installed at one end of the threaded sleeve 31, and a transmission spring 33 is welded to one side of the sliding sleeve 29. The other end of the transmission spring 33 is welded to the surface of the pressure module 32. By pressing the monitoring component 4 directly onto the ground and moving it through a power device, the pressure module 32 can indirectly determine the current slippage situation on the highway, thereby determining the icing state. This makes the final obtained icing situation more reflective of the current road information and more reliable.

[0032] Specifically, after starting the motor 5, the motor 5 drives the lead screw 6 to rotate. The lead screw 6, in conjunction with the threaded sleeve 31, can drive the second support frame 30 to move along the surface of the lead screw 6. On the side of the second support frame 30, the pressure module 32 and the transmission spring 33 control the movement of the first support frame 28. However, since there is a gap between the sliding sleeve 29 on the first support frame 28 and the lead screw 6, and the bottom transmission frame 17 is pressed against the ground by the pressing mechanism 8, the first support frame 28 generates resistance. The greater the friction between the bottom road surface and the pressing wheel 21, the greater the force required for the transmission spring 33 to push the first support frame 28. This force can then be transmitted to the pressure module 32 through the compression of the transmission spring 33 to quantify the degree of friction between the pressing mechanism 8 and the ground. Both the first support frame 28 and the second support frame 30 achieve a stable effect by passing through the strip hole 11.

[0033] In this embodiment, an extension arm 18 is installed at the bottom of the transmission frame 17, and a ranging module 19 is screwed to the end of the extension arm 18. A clamping plate 20 is integrally formed at the bottom of the extension arm 18. The pressing mechanism 8 includes a pressing wheel 21, a support plate 24, and a rotating plate 26. A sandwich layer 22 is formed in the middle area of ​​the surface of the pressing wheel 21, and a stop bar 23 is installed on the inner side of the sandwich layer 22. The two ends of the pressing wheel 21 are connected to the end of the clamping plate 20 by a shaft. A support plate 24 is welded to the inner wall of the clamping plate 20. A lower hanging plate 25 is integrally formed at the bottom of the support plate 24, and the rotating plate 26 is hinged to the bottom end of the lower hanging plate 25. The rotating plate 26 has an inclined plate 27 at its end, which is embedded into the interior of the interlayer 22. The inclined plate 27 rests against the stop bar 23 through its vertical surface and is vertically embedded into the interior of the interlayer 22. The rotating plate 26 rotates around the bottom of the lower hanging plate 25 via a hinge. By monitoring the pressing mechanism 8 at the bottom of the component 4, which presses directly onto the ground, the contact position between the pressing mechanism 8 and the ground can be automatically switched during each cycle of movement. This reduces the wear problem caused by the sliding friction between the pressing wheel 21 and the ground due to its fixed position. In conjunction with the cleaning component 12, the contact position of the pressing wheel 21 can be cleaned after each test, improving the reliability of subsequent tests.

[0034] For details, please refer to Figure 1 and Figure 2 In the two figures, when the motor 5 rotates and drives the entire monitoring component 4 toward the interior of the cleaning chamber 1, friction is generated between the bottom of the pressing wheel 21 and the ground. Due to the vertical plate of the rotating plate 26 blocking one side of the stop bar 23, the pressing wheel 21 does not rotate during this process and can only move by sliding friction with the ground. During this process, the icing phenomenon on the ground can be detected. At the same time, with the help of the movement of the extension arm 18, in conjunction with the distance measuring module 19 at the end, it can detect whether there is snow accumulation on the highway ground corresponding to the side of the track. When there is snow accumulation, the laser beam generated by the distance measuring module 19 directly irradiates the snow accumulation, and the change in the measured distance can be detected. The entire measurement process can achieve the purpose of monitoring a long distance within the track coverage area. The pressing mechanism 8 is inserted into the bottom of the first support frame 28 through the plug 34 to ensure that the entire pressing mechanism 8 can be pressed onto the ground by its own weight.

[0035] In this embodiment, the bottom of the cleaning chamber 1 is integrally formed with a base plate 9. One end of the base plate 9 has a groove 10. The cleaning assembly 12 is installed inside the groove 10. The cleaning assembly 12 includes a telescopic sleeve 13, a spring rod 14, a top plate 15, and a sponge pad 16. One end of the telescopic sleeve 13 is welded to the inner wall of the cleaning chamber 1. The spring rod 14 is inserted inside the telescopic sleeve 13. The top plate 15 is welded to the end of the spring rod 14. The sponge pad 16 is attached to the end of the top plate 15. The sponge pad 16 has an overall arc-shaped structure and is used to abut against the surface of the pressing wheel 21.

[0036] Specifically, when the control press wheel 21 moves towards the power chamber 2, the stop lever 23 rotates in the opposite direction, which can impact the rotating plate 26 from one side of the inclined plate 27. At this time, the rotating plate 26 can flip to the side through the top hinge to avoid affecting the stop lever 23. This allows the entire press wheel 21 to rotate. Once the press wheel 21 rotates, it can change the contact position between the press wheel 21 and the ground in the next monitoring process. At the same time, when the press wheel 21 is inserted into the cleaning chamber 1, it will directly press the sponge pad 16 against the surface of the press wheel 21, and the spring rod 14 will be compressed. When the press wheel 21 moves away from the cleaning chamber 1, the press wheel 21 can rotate normally. During this rotation, the spring rod 14 always presses the sponge pad 16 against the sponge pad 16, thereby achieving the cleaning purpose with the help of the sponge pad 16.

[0037] This embodiment also provides a monitoring system using the above-mentioned monitoring device. The monitoring system includes a core processing layer, a front-end sensing layer, and a data transmission layer. The core processing layer is equipped with a data fusion engine and a decision support system. The front-end sensing layer includes a pressure sensor, a temperature sensor, and a ranging sensor. The data transmission layer provides wired communication and dedicated short-range wireless communication.

[0038] This monitoring system can detect snow accumulation on the ground over a large area, expanding the monitoring range. It can also simultaneously acquire the friction force of the highway surface within the same range while monitoring snow accumulation, ultimately obtaining more detailed information on snow accumulation and icing on that section of the road.

It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
