Description

Technical Field

[0001] The present invention belongs to the technical field of traffic management, and in particular relates to a method for remote monitoring of highways based on the Internet of Things. Background Art

[0002] Expressways are an important part of the transportation system. Unlike railway and air transport systems, the safety of expressway transport systems is often controlled by drivers. Once a high-speed safety accident occurs due to driver error, it often leads to one-way or even two-way road congestion. In this case, the use of emergency lanes on expressways plays a vital role. Rescue vehicles, police vehicles, etc. often need to use emergency lanes to reach the accident site to handle the accident and rescue people.

[0003] However, the disadvantage of the existing highway monitoring system is that emergency lane occupancy capture is achieved by setting up cameras. The radiation range of the cameras is limited, and the distance between the cameras is large. This has led to many drivers taking chances and occupying the emergency lane in the blind spots where the emergency lane is captured. This may pose an urgent threat to accident handling and rescue efforts on the highway.

[0004] Therefore, it is necessary to monitor and manage the illegal occupation of emergency lanes on highways, especially on sections of roads with traffic jams, to ensure road traffic safety and personal safety. Summary of the Invention

[0005] To solve the above technical problems, this application proposes a highway remote monitoring method based on the Internet of Things. The specific technical solution is as follows:

[0006] A remote monitoring method for highways based on the Internet of Things, the method comprising:

[0007] Obtain abnormal traffic conditions on highways and mark them;

[0008] Obtain recording equipment on the highway that is within the range of abnormal traffic conditions;

[0009] The emergency lane is recorded using video recording equipment, and the illegal occupation of the emergency lane is uploaded to the platform.

[0010] Furthermore, valid recording devices among the recording devices are screened to record the emergency lane, wherein the valid recording devices are recording devices located in a lane adjacent to the emergency lane.

[0011] Furthermore, the method for effectively recording a device includes:

[0012] Manually set the recording device as a valid recording device;

[0013] Or the recording device automatically determines and sets it as a valid recording device.

[0014] Furthermore, the method for automatically determining and setting the recording device as a valid recording device is as follows:

[0015] The recording device obtains pictures or video frames, and determines whether the vehicle body duty cycle in the pictures or video frames is greater than a preset value. If so, it is set as a valid recording device. The vehicle body duty cycle refers to the ratio of the area not occupied by the vehicle in the frame image of the picture or video to the total area of the image.

[0016] Furthermore, abnormal traffic conditions on the highway are obtained through navigation software, and the navigation software has a mobile network access function.

[0017] Furthermore, when a terminal on which the navigation software is installed is within the range affected by an abnormal traffic condition, the navigation software will generate an abnormal condition carrying its location information and upload it to the platform.

[0018] Furthermore, the navigation software is bound to the unique identification information of the recording device. After the platform receives the abnormal status uploaded by the navigation software, it establishes a connection with the recording device with the unique identification information bound to the navigation software.

[0019] Furthermore, the platform provides an interface to connect with the system of the traffic law enforcement management department, upload the data of illegal occupation of emergency lanes, and notify the processing results via SMS after confirmation by the traffic law enforcement management department.

[0020] The beneficial effects of the present invention are:

[0021] The Internet of Things-based highway remote monitoring method provided in the present invention combines existing navigation technology and recording technology. When an abnormal situation occurs during highway driving and congestion occurs, a connection is established with an effective recording device while accurately locating the congestion point. The recording function of these recording devices themselves provides timely scene requirements for shooting illegal occupation of emergency lanes. It has higher efficiency and full coverage for the illegal occupation of emergency lanes during highway traffic jams, and can effectively solve the problem of insufficient coverage of single-point capture of emergency lane occupancy by cameras. At the same time, this method fully and reasonably utilizes existing social resources and hardly increases the burden on traffic law enforcement management departments.

[0023] Figure 2 Shown are example pictures of the automatic judgment process of the recording device. DETAILED DESCRIPTION

[0024] In the following description, certain specific details are set forth in order to provide a thorough understanding of the various embodiments. However, it will be understood by those skilled in the art that the present invention can be practiced without these details. In other cases, well-known structures are not shown or described in detail to avoid unnecessarily obscuring the description of the embodiments. Unless the context requires otherwise, throughout the specification and the appended claims, the word "comprising" should be interpreted in an open, inclusive sense, that is, as in "including but not limited to."

[0025] Figure 1 The present invention shows a method for remote monitoring of highways based on the Internet of Things. The method is as follows:

[0026] Obtain abnormal traffic conditions on highways and mark them;

[0027] Obtain recording equipment on the highway that is within the range of abnormal traffic conditions;

[0028] Filter valid recording devices among the recording devices and establish a connection;

[0029] The emergency lane is recorded through effective recording equipment, and the illegal occupation of the emergency lane is uploaded to the monitoring platform.

[0030] In the implementation plan, methods for acquiring abnormal traffic conditions on highways include, but are not limited to, navigation systems, vehicle-mounted systems, and road traffic monitoring systems. However, this application requires ensuring the immediacy and location of abnormal traffic conditions. Therefore, a vehicle-mounted system or navigation system with network data transmission is generally required. Essentially, it requires real-time acquisition of vehicle location and movement status information. Therefore, this can be navigation software installed on a mobile terminal (such as a mobile phone or tablet) or on the vehicle-mounted system.

[0031] Based on this, when the user (i.e. the driver) uses the navigation software for assisted driving, the navigation software can obtain the location information and movement status information of the vehicle driven by the user in real time, and the navigation software itself has the function of identifying and reporting abnormal traffic conditions. When a traffic accident or other situation occurs on the road where the user is driving, causing traffic to be blocked, once the vehicle driven by the user is within the range of influence of the abnormal traffic condition, the navigation software can identify it.

[0032] In the implementation plan, abnormal traffic conditions on the highway are not limited to traffic obstructions caused by traffic accidents, but also include situations where the entire road section is obstructed due to illegal driving, parking, low-speed driving, etc.

[0033] Based on this, obtaining and marking abnormal traffic conditions on highways is performed using the navigation software system service function, and this execution step is usually performed on the server side of the navigation software system. When the server obtains the vehicle's movement status data and determines through calculation that there is an abnormal traffic condition, it will mark the location of the abnormal traffic condition.

[0034] Furthermore, after using the navigation software system to obtain abnormal traffic conditions on the highway and mark the location, the navigation software system can generate the impact range of the abnormal traffic conditions by obtaining the driving data of vehicles on the same road section, and further mark the vehicles within the impact range of the abnormal traffic conditions (essentially, vehicles using the navigation software).

[0035] In the implementation plan, when a vehicle is within the range of influence of an abnormal traffic condition, it is first necessary to obtain the recording equipment on the highway within the range of influence of the abnormal traffic condition. The recording equipment within the range of influence of the abnormal traffic condition can be used to record the illegal occupation of the emergency lane.

[0036] The recording device can be a machine specifically used for recording, or it can be a device with recording function, such as a driving recorder, a recording camera of a vehicle system, a mobile terminal, etc. What needs to be noted is that in addition to the recording function, the recording device should also have at least storage function and network transmission function, so as to cache the recorded content and upload the cached recorded content through the network transmission function.

[0037] Since the emergency lane is usually set on one side of the road (such as the right side of the road), the recording equipment that is convenient for recording illegal occupation of the emergency lane is the lane adjacent to the emergency lane. Therefore, it is necessary to screen the recording equipment within the range affected by the abnormal traffic conditions to obtain the recording equipment on the lane adjacent to the emergency lane. The purpose of doing this is to increase the effective recording content and avoid other recording equipment from increasing unnecessary processing load.

[0038] Regarding how to screen out valid recording devices among the recording devices, in the implementation plan, one solution that can be adopted is: manual setting, that is, when there are other passengers in the vehicle in addition to the driver, they can manually confirm that the vehicle they are riding in is located in the lane adjacent to the emergency lane, and confirm the manual screening results. In this way, the recording device on the vehicle can become a valid recording device.

[0039] Regarding how to screen out valid recording devices from the recording devices, in the implementation plan, another solution that can be adopted is: the recording device automatically determines, the recording device obtains data in picture or video format at the driving angle of the vehicle, uses intelligent recognition to obtain characteristic elements in the picture or video screen, and determines whether the vehicle is located in a lane adjacent to the emergency lane based on the characteristic elements.

[0040] More specifically, the characteristic element obtained from the picture or video is the vehicle body duty cycle. When the vehicle body duty cycle is greater than a preset value K (generally K can be set to 0.3), it can be determined that the vehicle is located in a lane adjacent to the emergency lane.

[0041] The definition of the vehicle body occupation ratio recorded above is the ratio of the area not occupied by the vehicle in a picture or a frame of a video to the total area of the image.

[0042] Based on this, the automatic judgment process of the recording device is as follows:

[0043] The recording device obtains images at the vehicle's driving angle;

[0044] Identify the vehicle in the image and mark it with a bounding box;

[0045] Scan horizontally from top to bottom until the horizontal line touches the bounding box, cut off the part scanned by the horizontal line, and calculate the total area S1 of the remaining image;

[0046] Scan from one side to the other using a vertical line and calculate the total scan area S2 of the vertical line that touches the bounding box;

[0047] Body duty cycle = S2 / S1, Figure 2 Shown is an exemplary picture.

[0048] Multiple images or a continuous video can be obtained for judgment. When multiple images are used for judgment, a voting method is used to determine the judgment result, that is, the image with the same judgment result is selected as the final judgment result to avoid the vehicle being in the lane adjacent to the emergency lane. However, when the image is obtained, a vehicle happens to pass through the emergency lane, resulting in a vehicle duty cycle that is too low.

[0049] When a continuous video is used for judgment, several frames are extracted from the video and the same operation as for the picture is performed.

[0050] In the real-time solution, it is necessary to obtain media management permissions for valid recording equipment in order to record the emergency lane through valid recording equipment and upload the corresponding evidence of illegal occupation of the emergency lane to the platform.

[0051] Obtaining the media management permission of a valid recording device can be temporary, that is, directly obtaining the temporary media management permission after the ordinary recording device is converted into a valid recording device, or obtaining the temporary media management permission through manual confirmation after the ordinary recording device is converted into a valid recording device. For example, the driving recorder integrated in the vehicle system is connected to the vehicle system. When the driving recorder is converted into a valid recording device, the temporary media management permission of the driving recorder can be obtained through a pop-up window on the vehicle display after confirmation by the driver or passenger.

[0052] Of course, obtaining the media management authority of a valid recording device can also be set in advance. Generally speaking, by signing an electronic agreement in advance, it is defaulted that when the recording device is converted to a valid recording device, the media management authority of the recording device is directly obtained.

[0053] In the implementation plan, after the emergency lane is recorded by effective recording equipment to obtain images or video footage of vehicles illegally occupying the emergency lane, the images or video footage need to be uploaded to the management platform in a timely manner for unified management by the management platform. The management platform here is a platform set up by a third party independent of the transportation management or traffic law enforcement department to ensure security between different management systems.

[0054] In the implementation plan, based on the management platform, three-party authorization is also required among the management platform, the recording device and the navigation software. By binding the unique identification information of the recording device to the navigation software and authorizing the recording device and the navigation software on the management platform, the management platform obtains the data transmission permission of the recording device, as well as the location information permission and binding data permission of the navigation software.

[0055] When the navigation software's server detects an abnormal traffic condition and identifies all navigation software within its affected area, each navigation software within that area will generate an abnormal status message containing its location information. The management platform, through appropriate permissions, will then access the corresponding recording device bound to the navigation software and establish a data connection with the recording device with unique identification information, allowing subsequent judgment and recording to be performed through the recording device. Generally speaking, only after the navigation software generates an abnormal status message containing its location information and sends it to the management platform will the management platform establish a data connection with the recording device bound to it with unique identification information.

[0056] The management platform can provide an interface for the transportation management or traffic law enforcement department's system to access and obtain relevant data. The transportation management or traffic law enforcement department can obtain relevant evidence of illegal occupation of emergency lanes in a timely manner through the interface opened by the management platform, and then make timely and accurate handling.

[0057] More importantly, by connecting the management platform with the systems of transportation management or traffic law enforcement departments, not only can the illegal occupation of emergency lanes be dealt with promptly and accurately, but the internal systems of traffic law enforcement departments and relevant drivers can also be notified, such as by sending short messages through the contact information reserved during vehicle registration, to directly notify them of the results of the handling, reminding the relevant drivers to stop illegally occupying emergency lanes, and guiding them to drive in accordance with the law and give up the emergency lane.

[0058] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
