Description

Technical Field

[0001] The utility model relates to the technical field of traffic control systems, in particular to an autonomous road traffic monitoring device during construction. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] During road construction, traffic congestion and traffic accidents often occur due to factors such as lane occupation, changes in road conditions, and unclear traffic guidance. At the same time, the entry and exit of construction vehicles and equipment, as well as temporary fences and obstacles, usually change the original lane layout, and as the construction progresses, the lanes will also change at any time, which makes it impossible to update traditional monitoring and control facilities in a timely manner, resulting in vehicles often not driving in the right lane. At the same time, due to unclear traffic guidance, drivers are prone to lose their way and mistakenly enter the opposite lane or the construction area, thereby increasing the risk of traffic accidents.

[0004] To address the above issues, the prior art generally places temporary traffic guidance facilities on the road sections or intersections affected by the construction area, and reminds drivers of the existence of the construction area nearby through signal lights, guidance signs or text. However, most of these traffic guidance facilities are mobile in order to facilitate adjustment of their positions. When hit by a vehicle, they are easily knocked over, causing damage to the equipment they carry. Utility Model Content

[0005] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides an autonomous road traffic monitoring device for construction periods, which is fixedly installed at a set position affected by the construction, and absorbs the impact caused by vehicle collision through anti-collision guardrails and protective shells. The shape and structural design of the protective shell lowers the center of gravity distribution of the entire device, thereby reducing the possibility of being knocked over. At the same time, the structure of the protective shell is used to improve the strength to avoid damage to the equipment installed inside.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The utility model provides an autonomous road traffic monitoring device for construction periods, comprising a protective shell and an anti-collision guardrail, wherein the interior of the protective shell is used to accommodate a communication module, a processor and a battery assembly, a signal light, a monitoring radar, a camera and a solar panel are arranged in the space above the protective shell, and the protective shell is connected to the interior of the space enclosed by the anti-collision guardrail; the protective shell comprises at least six groups of side panels connected end to end, the top of each group of side panels is connected to a structural column through a sub-plate, the bottoms of all the side panels are connected to a bottom plate, and a plurality of groups of columns are arranged on the lower bottom surface of the bottom plate.

[0008] Furthermore, each set of side panels is arranged obliquely, and the protective shell forms a cavity distributed in the vertical direction and with gradually increasing space.

[0009] Furthermore, the cross-section of the space formed by the protective shell is a regular hexagon.

[0010] Furthermore, the communication module, the processor and the battery assembly are fixed on the upper surface of the base plate.

[0011] Furthermore, the anti-collision guardrail is a corrugated beam.

[0012] Furthermore, the anti-collision guardrail is enclosed at the bottom end of the outer side of the protective shell.

[0013] Furthermore, the solar panel is connected to the top of the structural column, the space below the solar panel is provided with a monitoring radar and a camera, and the space below the monitoring radar and the camera is provided with a signal light.

[0014] Furthermore, the cross section of the solar panel is in the shape of a human figure.

[0015] Furthermore, the camera and the monitoring radar form a perception module for obtaining traffic flow information in the corresponding direction.

[0016] Furthermore, there is an information release screen, which is arranged on the road affected by the construction area. The information release screen is communicatively connected with the communication module for releasing traffic reminder information.

[0017] Compared with the prior art, one or more of the above technical solutions have the following beneficial effects:

[0018] 1. When accidentally hit by a vehicle, the anti-collision guardrail and the protective shell absorb the impact caused by the collision, ensuring that the internal communication module, processor and battery assembly operate reliably and will not be damaged by the impact of the vehicle; at the same time, the communication module, processor and battery assembly are relatively heavy devices. When arranged in the protective shell, they are connected to the bottom plate to lower the center of gravity of the entire device. With the inclined side plate, the device is more stable. When accidentally hit by a vehicle, the entire device is not easily knocked over, thereby ensuring that the communication module, processor and battery assembly can operate reliably.

[0019] 2. The protective shell with a regular hexagonal cross-section is different from the traditional cylindrical protective shell. The area where multiple side panels are connected end to end forms a structure similar to "ribs", which can improve the strength of the protective shell while maintaining the same consumption of materials, thereby better protecting the internal communication module, processor and battery components.

[0020] 3. After the camera and monitoring radar obtain traffic flow information, the processor identifies abnormal situations such as traffic congestion and accident risks, and sends the abnormal situation information to the information release screen through the communication module. The information release screen is used to guide vehicles that are about to pass through the construction area and remind passing vehicles that there are construction sections. On the one hand, it improves the traffic situation, and on the other hand, it reduces the probability of the device being hit. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0026] It should be noted that the following detailed descriptions are exemplary and are intended to provide further description of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0027] As introduced in the background technology, during road construction, traffic congestion and traffic accidents often occur due to factors such as lane occupation, changes in road conditions, and unclear traffic instructions. At the same time, the entry and exit of construction vehicles and equipment, as well as temporary fences and obstacles, usually change the original lane layout, and as the construction progresses, the lanes will also change at any time, which makes it impossible to update traditional monitoring and control facilities in a timely manner, resulting in vehicles often not driving in the right lanes. At the same time, due to unclear traffic instructions, drivers are prone to lose their way and mistakenly enter the opposite lane or the construction area, thereby increasing the risk of traffic accidents.

[0028] In order to address the above-mentioned problems, the prior art generally places temporary traffic guidance facilities on the road sections or intersections affected by the construction area, and reminds the driver of the existence of the construction area nearby through signal lights, guidance signs or text. However, such traffic guidance facilities change the driver's attention habits and are easily hit by vehicles. In addition, most of these temporary traffic guidance facilities are mobile in order to facilitate the adjustment of their positions. When hit by a vehicle, they are easily knocked over, causing damage to the equipment they carry.

[0029] Therefore, the following embodiment provides an autonomous road traffic monitoring device for use during construction, which is fixedly installed at a set position affected by the construction, and absorbs the impact of vehicle collisions through anti-collision guardrails and protective shells. The shape and structure design of the protective shell lowers the center of gravity distribution of the entire device, thereby reducing the possibility of being knocked over. At the same time, the structure of the protective shell is used to improve the strength to avoid damage to the equipment inside.

[0030] like Figure 1 As shown, an autonomous road traffic monitoring device for use during construction includes a protective shell 5 and an anti-collision guardrail 9. The interior of the protective shell 5 is used to accommodate a communication module 6, a processor 7 and a battery assembly 8. The space above the protective shell 5 is provided with a signal light 4, a monitoring radar 3, a camera 2 and a solar panel 1. The protective shell 5 is connected to the space enclosed by the anti-collision guardrail 9 and is fixed at a set position by a column 10.

[0031] In this embodiment, the anti-collision guardrail 9 is a corrugated beam guardrail.

[0032] In this embodiment, the cross-section of the space formed by the protective shell 5 is a regular hexagon, including six groups of side panels connected end to end, the top of each group of side panels is connected to the structural column through a sub-panel, and the bottoms of all side panels are connected to the bottom plate. A plurality of groups of columns 10 are provided on the lower bottom surface of the bottom plate. Each group of side panels is arranged obliquely to form a cavity arranged in a vertical direction and with gradually increasing space, and the anti-collision guardrail 9 is enclosed on the outer side of the bottom end of the protective shell 5.

[0033] The signal light 4, monitoring radar 3, camera 2 and solar panel 1 are connected to the structural column. Specifically, the top of the structural column is connected to the solar panel 1, and the space below the solar panel 1 is provided with the monitoring radar 3 and camera 2, and the space below the two is provided with the signal light 4.

[0034] The signal light 4 is used to send out traffic guidance signals to the intersection being headed toward, and the monitoring radar 3 and the camera 2 are used to obtain traffic flow information of the intersection being headed toward.

[0035] In this embodiment, the cross section of the solar panel 1 is in the shape of a human figure. On the one hand, it can obtain light from different angles and improve the photoelectric conversion efficiency of the solar panel 1. On the other hand, the structure of the human figure has a certain rainproof function, which can reduce the amount of rainwater invading the camera 2 and the monitoring radar 3 in the space below, and reduce the probability of their failure. The use of solar power supply enables the device to have independent power supply capability, and the battery assembly 8 is used as a backup power supply in an emergency state.

[0036] The communication module 6, processor 7 and battery assembly 8 are arranged inside the protective shell 5. The communication module 6, processor 7 and battery assembly 8 are devices that are easily damaged by vehicle impact, so they are surrounded by the protective shell 5; at the same time, the communication module 6, processor 7 and battery assembly 8 are devices with relatively large weight, and when arranged in the protective shell 5, the center of gravity of the entire device is lowered; at the same time, the inclined side panels make the protective shell 5 form a "small top and large bottom" space, further lowering the center of gravity of the device, making the device more stable and not easily knocked over when accidentally hit by a vehicle, thereby ensuring that the communication module 6, processor 7 and battery assembly 8 can operate reliably.

[0037] When accidentally hit by a vehicle, the anti-collision guardrail 9 with a corrugated beam structure will absorb part of the impact, and the protective shell 5 will absorb the remaining impact, ensuring that the internal communication module 6, processor 7 and battery assembly 8 operate reliably and will not be damaged by the impact of the vehicle.

[0038] The protective shell 5 with a regular hexagonal cross-section is different from the traditional cylindrical protective shell. The area where multiple side panels are connected end to end forms a structure similar to "ribs", which can improve the strength of the protective shell 5 while maintaining the same consumable materials, thereby better protecting the internal communication module 6, processor 7 and battery assembly 8.

[0039] In this embodiment, the camera 2 and the monitoring radar 3 form a perception module to achieve all-weather, all-round video monitoring. The monitoring radar 3 is used to monitor traffic flow and speed, and the camera 2 is used to obtain vehicle information on the road. The collected information is sent to the processor 7 for further processing.

[0040] Processor 7 integrates data calculation, traffic prediction and other technologies, performs real-time analysis on the collected traffic data, identifies abnormal situations such as traffic congestion and accident risks, and predicts the trend of traffic flow changes to provide a basis for the decision-making of the information release module. The algorithm executed by processor 7 is an existing technology and will not be described in detail in this embodiment.

[0041] The information release module is an information release screen. Specific prompt information is set according to the characteristics of the device installation location (for example, if the opposite lane is occupied, a reminder to prevent accidental entry into the opposite lane should be given), and abnormal conditions or traffic induction information is displayed through the information release screen based on the data analysis results to guide vehicles to bypass the construction area, alleviate traffic pressure, or remind passing vehicles that they are about to pass through the construction area.

[0042] The high-speed communication method of 4G wireless communication can be used to realize the communication connection between the information release screen and the communication module 6, as well as the communication connection between the background control center and the communication module 6, to ensure the real-time internal transmission and processing of the monitoring data; at the same time, traffic management personnel can remotely monitor road traffic conditions and adjust management strategies in real time through the background control center loaded on terminal devices such as computers and mobile phones.

[0043] In this embodiment, Figure 2 As shown, the construction area 12 is located in a certain road section, and the device is arranged at the intersection before entering the road section where the construction area 12 is located. The camera 2 and the monitoring radar 3 acquire traffic flow information toward the four road sections, and the traffic light 4 issues intersection guidance information toward the four intersections. An information release screen 11 is set on the four roads affected by the construction (entering and exiting the construction section, and the section intersecting with the construction section) to remind passing vehicles that there is a construction area and to slow down.

[0044] The monitoring radar 3 and the camera 2 collect big data and send it to the processor through the data collector. The traffic light issues traffic guidance signals according to the instructions issued by the processor. The background control center connects with the processor through the communication module to realize remote monitoring, and pushes reminder information through the information release screen or information release terminal to remind passing vehicles that there is a construction area. In this embodiment, the information release terminal can be software installed in the vehicle computer or mobile phone APP.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
