Abstract
Description
Technical Field
[0001] This application relates to the field of electronic circuit technology, and in particular to a rear-end collision prevention guidance light system. Background Technology
[0002] Rear-end collisions are frequent on highways, primarily caused by factors such as slow-moving vehicles and illegal parking. The core issue in these accidents lies in drivers' misjudgment of the movement of vehicles ahead. Even when maintaining a safe following distance, high speeds make it difficult for drivers to accurately determine whether a vehicle ahead is moving or stationary, leading to a misperception of speed. By the time drivers realize their mistake, it is often too late to avoid an accident.
[0003] Therefore, there is an urgent need for those skilled in the art to provide a solution to avoid rear-end collisions. Summary of the Invention
[0004] This application provides a rear-end collision prevention guidance light system that reduces rear-end collision accidents on highways through real-time monitoring and alerts.
[0005] In view of the above, the first aspect of this application provides a rear-end collision avoidance guidance light system, the system comprising:
[0006] The lane is equipped with guide lights, radar for scanning lanes, and controllers.
[0007] The controller is communicatively connected to the guide light group and the radar, respectively.
[0008] The radar is used to scan and update the position and speed information of each vehicle in the lane, and then send the position and speed information to the controller.
[0009] The controller sends control information to a number of guide lights in the guide light group corresponding to the location of the vehicle that is determined to be at risk of rear-end collision, based on the location information and the speed information, so that the number of guide lights flash as a warning.
[0010] Optionally, it also includes a speaker assembly;
[0011] The speaker assembly is connected to the controller;
[0012] The controller sends control information to the speaker group, causing the speaker group to provide sound prompts.
[0013] Optionally, the controller includes a computing unit and a processing unit;
[0014] The computing unit is used to receive the location information and speed information sent by the radar, and after locating the vehicle with rear-end collision risk based on the location information and speed information, send the corresponding vehicle location information to the processing unit.
[0015] The processing unit sends control information to a plurality of guide lights in the corresponding guide light group according to the location information, causing the plurality of guide lights to flash as a prompt.
[0016] Optionally, the controller is further configured to, if it is determined based on the location information and the speed information that the vehicle has escaped the risk of a rear-end collision, send control information to a plurality of guide lights in the guide light group at the corresponding position of the vehicle, so that the plurality of guide lights stop flashing as a warning.
[0017] Optionally, the controller is further configured to send control information to the speaker group if it is determined, based on the location information and the speed information, that the vehicle has escaped the risk of a rear-end collision, so that the speaker group stops the sound prompts.
[0018] As can be seen from the above technical solutions, the embodiments of this application have the following advantages:
[0019] This application provides a rear-end collision prevention guidance light system, including: guidance light groups installed on both sides of a lane, radar for scanning the lane, and a controller; the controller is communicatively connected to the guidance light groups and the radar; wherein, the radar scans and updates the position and speed information of each vehicle in the lane, and then sends the position and speed information to the controller; the controller, based on the position and speed information, sends control information to several guidance lights in the guidance light groups corresponding to vehicles deemed to have a rear-end collision risk, causing the guidance lights to flash as a warning. The system uses radar tracking data to determine the speed of each vehicle, compares the speeds of adjacent vehicles in the same lane, and determines the speed difference and distance. When the speed difference exceeds a threshold, a light or sound warning is activated to remind following vehicles to brake, achieving real-time monitoring and warning to reduce rear-end collisions on highways.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.
[0022] For easier understanding, please refer to Figure 1 , Figure 1 This is a system structure diagram of the rear-end collision prevention guidance light system in the embodiments of this application, as shown below. Figure 1 As shown, specifically:
[0023] The guide light group 1, the radar 2 used to scan the lane, and the controller are installed on both sides of the lane;
[0024] The controller is communicatively connected to both the guide light group 1 and the radar 2.
[0025] Among them, radar 2 is used to scan and update the position and speed information of each vehicle in the lane, and then send the position and speed information to the controller.
[0026] Based on the location and speed information, the controller sends control information to several guide lights in the guide light group 1 at the location of the vehicle that is identified as having a rear-end collision risk, causing the guide lights to flash as a warning.
[0027] Furthermore, it also includes speaker assembly 3;
[0028] Speaker group 3 is connected to the controller;
[0029] The controller sends control information to speaker group 3, causing the speaker group to provide sound prompts.
[0030] Furthermore, the controller includes a computing unit 41 and a processing unit 42;
[0031] The calculation unit 41 is used to receive the position information and speed information sent by the radar 2, and after locating the vehicle with the risk of rear-end collision based on the position information and speed information, it sends the corresponding vehicle position information to the processing unit 42.
[0032] The processing unit 42 sends control information to several guide lights in the corresponding guide light group 1 according to the location information, so that the guide lights flash to provide a prompt.
[0033] Furthermore, if the controller determines that the vehicle is out of the risk of a rear-end collision based on the location information and speed information, it sends control information to several guide lights of the guide light group 1 at the corresponding position of the vehicle, so that the guide lights stop flashing as a warning.
[0034] Furthermore, if the controller determines, based on the location and speed information, that the vehicle is out of the risk of a rear-end collision, it sends control information to the speaker group 3 to stop the sound alert.
[0035] This system is a radar-based rear-end collision avoidance system, which consists of the following main components:
[0036] Guide light group 1:
[0037] They are placed on both sides of the lane to provide visual cues to drivers.
[0038] When the controller determines that a vehicle is at risk of being rear-ended, the corresponding guidance light in the guidance light group 1 will flash to remind the driver.
[0039] Radar 2:
[0040] It is used to scan lanes and update the position and speed information of each vehicle in the lane in real time.
[0041] This information is sent to the controller for further processing.
[0042] Controller:
[0043] It is communicatively connected to the guide light group 1 and radar 2.
[0044] It receives position and speed information from radar 2 and assesses the risk of a rear-end collision based on this information.
[0045] Send control information to guide light group 1 to control the flashing of the guide lights to remind the driver.
[0046] Send control information to speaker group 3 to control the sound prompts.
[0047] Speaker group 3:
[0048] Connects to the controller to provide audio cues.
[0049] When the controller determines that a vehicle is at risk of being rear-ended, speaker group 3 will emit an audible alert to remind the driver.
[0050] Controller internal structure:
[0051] Calculation Unit 31:
[0052] Receive position and speed information transmitted by radar 2.
[0053] Based on this information, vehicles at risk of rear-end collisions are located, and their corresponding location information is calculated.
[0054] Send the vehicle's location information to the processing unit 42.
[0055] Processing unit 42:
[0056] Receive vehicle location information sent by the computing unit 41.
[0057] Based on the location information, control information is sent to several guide lights in the corresponding guide light group 1, causing the guide lights to flash as a prompt.
[0058] Procedures for risk mitigation:
[0059] When the controller determines that the vehicle has escaped the risk of a rear-end collision based on the location and speed information:
[0060] Control information is sent to several guide lights in the guide light group 1 at the corresponding position of the vehicle to stop the guide lights from flashing.
[0061] Send control information to speaker group 3 to stop the sound prompts.
[0062] The workflow of the entire system is as follows:
[0063] Radar 2 scans the lane and collects information on the position and speed of vehicles.
[0064] The controller receives this information and the computing unit 31 analyzes it to determine whether there is a risk of rear-end collision.
[0065] If a risk is present, the processing unit 32 sends control information to the guide light group 1 and the speaker group 3 to activate visual and audible cues.
[0066] Once the risk is eliminated, the controller stops sending control information, and the guide lights and speakers stop providing alerts.
[0067] This system is designed to improve drivers' awareness of the status of vehicles ahead through real-time monitoring and timely alerts, thereby reducing rear-end collisions on highways.

The system uses radar tracking data to determine the speed of each vehicle, compares the speeds of adjacent vehicles in the same lane, and determines the speed difference and distance. When the speed difference exceeds a threshold, a light or sound warning is activated to remind the following vehicle to brake, achieving real-time monitoring and warning to reduce rear-end collisions on highways.
