Description

Technical Field

[0001] The invention relates to the field of road isolation and warning facilities, and in particular to an intelligent interactive roadblock system. Background Art

[0002] Roadblocks are a type of road traffic isolation and warning facility, mainly used to warn road users during construction or traffic accidents to ensure the personal safety of construction personnel and road users, or to divert traffic, separate or merge pedestrians and vehicles. Typical roadblocks are cone-shaped or column-shaped road signs with fluorescent red, blue, yellow, green and other warning colors, mostly made of synthetic resin. To increase visibility to drivers, roadblocks are generally attached with reflective strips.

[0003] At present, in order to solve the problem of the typical non-movable structure of roadblocks, manual operation is often required for their deployment and recovery, which not only increases labor costs, but also brings certain dangers to operators in some dangerous areas such as highways. Patent CN205100129U discloses a mobile intelligent roadblock, including a chassis and a cone 2. The chassis is provided with a main control board 7 and a drive motor 9 and a communication module 5 connected to the main control board 7. The drive motor 9 is connected to a drive wheel 4 arranged under the chassis; the communication module 5 is connected to the control device in a wired / wireless manner; and at least one universal wheel 3 is also arranged under the chassis. The roadblock of this patent is equipped with a drive wheel and a universal wheel under the chassis, which does not affect the stability and is convenient and free to move; and after the communication module is connected to the control device, autonomous control of traffic can be achieved through a remote control or an intelligent terminal without manual placement.

[0004] However, it is not realistic to drive the intelligent roadblock directly to the accident scene when the distance is far. First, the endurance requirement of the roadblock is relatively high, and second, it will delay time and fail to warn the accident scene in time. Therefore, in the face of the above problems, it is a technical problem that needs to be solved urgently to develop an intelligent interactive roadblock system that can select the movement mode of the roadblock according to the situation so that the roadblock can reach the accident scene in time. Summary of the invention

DETAILED DESCRIPTION

[0025] The central control terminal is used to obtain road condition information and accident scene information in the specified area according to the roadblock deployment request, and plan the first roadblock movement trajectory according to the road condition information and the accident scene information, and then perform a feasibility analysis on the roadblock moving to the accident scene by itself according to the first roadblock movement trajectory; when the analysis shows that the roadblock can move to the accident scene by itself, the first roadblock movement trajectory is sent to the corresponding roadblock; if the analysis shows that the roadblock cannot move to the accident scene by itself, the first roadblock movement trajectory is sent to the corresponding drone;

[0026] The drone is used to transport the roadblock to the accident site according to the received movement trajectory of the first roadblock;

[0027] The above-mentioned roadblock is used to automatically move to the accident scene according to the received first roadblock movement trajectory, and after arriving at the accident scene, start the image recognition module to obtain the first accident scene image information, and calculate the second roadblock movement trajectory based on the first accident scene image information combined with the roadblock layout standard, and then move to the automatic delivery point again according to the second roadblock movement trajectory.

[0028] By planning the first roadblock moving trajectory according to the road condition information and the accident scene information, conducting a feasibility analysis on the roadblock's self-movement to the accident scene according to the first roadblock moving trajectory, and then selecting the roadblock's movement method according to the feasibility, it can be ensured that the roadblock can arrive at the accident scene in time to give a warning; by planning the second roadblock moving trajectory according to the first accident scene image information after the roadblock arrives at the accident scene, the accuracy of roadblock placement can be improved.

[0029] According to one embodiment of the present application, the system further includes: a mobile terminal for uploading a roadblock deployment request and accident scene information to the central control terminal, and the accident scene information includes the accident scene positioning information and the accident scene image information. The mobile terminal carried by the road inspector or the driver and passenger is connected to the central control terminal in communication. When an accident is found, the user uploads the on-site deployment request on the mobile terminal and locates the section where the roadblock is needed on the map interface. If the section location is not clear, the surrounding landmarks can also be uploaded to the central control terminal through the mobile terminal to facilitate the central control terminal to locate the accident scene. The same positioning authority can also be directly opened to send an accident scene deployment request to the central control terminal, so that the central control terminal automatically locates the corresponding mobile terminal's positioning information after receiving the accident scene deployment request, and automatically detects the accident section.

[0030] According to one embodiment of the present application, a feasibility analysis of the roadblock moving by itself to the accident scene based on the movement trajectory of the first roadblock specifically includes: judging the distance length and the time required for movement based on the movement trajectory of the first roadblock, and when the distance length and the time required for movement are both less than a set threshold, the analysis concludes that the roadblock can move by itself to the accident scene; otherwise, the analysis concludes that the roadblock cannot move by itself to the accident scene.

[0031] According to one embodiment of the present application, the roadblock uploads its own positioning information in real time during the movement; when the roadblock moves to the accident scene, the acquired first accident scene image information is uploaded in real time, and the trajectory to be confirmed information is sent to the central control terminal after the second roadblock movement trajectory is calculated; the staff confirms whether the placement point of the roadblock is correct based on the first accident scene image information and the trajectory to be confirmed information. If the placement point of the roadblock is confirmed to be correct, trajectory confirmation information is sent to the roadblock, so that the roadblock moves to the automatic placement point according to the second roadblock movement trajectory; otherwise, a specified third roadblock movement trajectory is sent to the roadblock, so that the roadblock moves to the specified placement point according to the third roadblock movement trajectory.

[0032] According to one embodiment of the present application, Figure 1 and Figure 2As shown, the roadblock includes a vertebral body, a base 1 at the bottom of the vertebral body, and a walking mechanism 11 installed at the bottom of the base 1.

The roadblock receives instructions from the central control terminal through the controller 32 via the wireless communication module 33, and controls the walking mechanism 11, the image acquisition device 7 and the navigation module to work according to the instructions. When in use, the airbag 5 is inflated so that the airbag 5 supports the equipment mounting seat 6 and the equipment thereon, and then the roadblock is started to enter the working mode and move according to the instructions. During the centralized transportation process, the gas in the airbag 5 can be released as needed, so that the equipment mounting seat 6 and the image acquisition device 7 thereon can be stored in the storage slot 4 as the airbag 5 shrinks; the airbag 5 structure can not only play a supporting and shrinking role, but also play a certain shock absorbing role, and can provide corresponding protection for the equipment on the equipment mounting seat 6.
