[0002] The existing highway emergency avoidance method generally has an escape lane, and the location of the escape lane is not fixed, resulting in some places without an escape lane, which may still cause subsequent multiple consecutive car accidents. At the same time, the existing highway avoidance method generally also uses interval turns and other high-risk areas on the highway to set up signs to keep the distance between vehicles to remind drivers to have a certain risk avoidance awareness. Finally, when a car accident or other dangerous accident occurs in a place where there are no signs and escape lanes, the vehicle usually has a tripod to prevent the subsequent car accident.
[0003] However, the above-mentioned highway avoidance methods still have a series of hidden dangers. For example, if a vehicle has an accident on a straight road or at night, the following vehicles will not be able to avoid the accident immediately due to limited vision and speed, which may lead to multiple or continuous traffic accidents. At the same time, the hazard lights set on the highway for a long time will cause the output screen to be polluted by the weather environment, making the output screen display no longer clear, resulting in a reduced warning effect of the hazard lights.

[0022] The emergency trigger module is used to receive accident signals and start the risk avoidance process. The hardware of the emergency trigger module consists of a waterproof trigger button installed on the vehicle or on the roadside or an integrated GPS or Beidou positioning unit. The trigger logic of the emergency trigger module is to generate an encrypted signal after pressing the button, which contains the accident location coordinates and timestamp, and is transmitted to the central control module via the cellular network or DSRC.
[0023] The central control module is used to process signals and schedule the dynamic display of hazard lights. The communication protocol of the central control module adopts the low-latency MQTT protocol, and covers the range of 1 km before and after the accident point through edge computing nodes; under normal circumstances, the visual hazard lights in the hazard avoidance system remain green. The central control module activates the hazard lights in the corresponding area according to the accident location and issues color grading instructions (red / orange / yellow).
[0024] The dynamic display module is used to indicate the distance to the danger zone through a multi-color LED light source. The lighting classification strategy of the dynamic display module is as follows: core danger zone (0-300 meters): red high-brightness LED, flashing frequency 3Hz; transition zone (300-600 meters): orange LED, brightness linearly decreasing; warning zone (600-1000 meters): yellow always-on LED; safety zone (more than 1000 meters): green high-brightness LED, always on. The lighting area of the dynamic display module extends from the accident center area to both ends of the road, such as Figure 2 shown.
[0025] The cleaning and maintenance module is used to automatically clean the output screen to maintain display clarity. The triggering logic of the cleaning and maintenance module is automatically triggered through daily scheduled cleaning or based on environmental sensors (such as rain and snow detection) to regularly clean the output screen on the hazard light to maintain clarity.
[0026] The power supply module is used to supply energy to the evacuation system. The power supply module includes solar power supply and power supply by wires. At the same time, a power storage unit is set to ensure the continuous supply of electricity. When an accident occurs in the power supply by wires, solar power is used for power supply and / or the sun stores power in the power storage unit and supplies power. The power storage unit has a built-in lithium battery, which can support at least 7 consecutive days of operation in rainy weather.
[0027] The reset management module is used for professionals to authorize the system to reset. The reset management module's authority verification is done by inserting a physical key into the reset hole or NFC identity authentication; double confirmation, local reset operations must be synchronized with cloud instructions to prevent accidental touches.
[0028] In this embodiment, the emergency trigger module, central control module, dynamic display module, cleaning and maintenance module, power supply module and reset management module cooperate with each other through electrical signals.
[0029] Process description: S1. The driver triggers the emergency button and the signal is transmitted to the central control module; S2. The control module defines the danger zone and activates the hazard lights; S3. The dynamic display module starts the graded light warning; S4. Cleaning module cleans the output screen regularly or on demand; S5. After the accident is handled, professionals authorize the system to be reset.

The gear assembly 32 includes a gear plate, a fixed wheel 321 and a connecting plate 322, and a uniform tooth block is provided on the outer periphery of the gear plate so that the gear plate and the first tooth groove 311 match each other. A fixed wheel 321 is provided through the middle of the gear plate, and the fixed wheel 321 is rotatably connected to the gear plate. The connecting plate 322 is located at the outer end of the fixed wheel 321, and one end of the connecting plate 322 is fixedly connected to the fixed wheel 321.
[0034] The sliding plate 33 is located at the opposite end surface of the fixed plate 31, and a second tooth groove 331 is provided at one end of the sliding plate 33 close to the first tooth groove 311, and the second tooth groove 331 matches with the gear plate, so that a gear assembly 32 is provided between the fixed plate 31 and the sliding plate 33.

[0039] The outer diameter of the push-out column 223 matches the inner diameter of the limiting hole 363-1, so that when the scraper 36 moves to the lower end surface, the limiting column 362-2 is pushed out to reset the scraper 362. The vertical height of the push-out column 223 matches the limiting hole 363-1, so that the push-out column 223 enters the limiting hole 363-1 to completely push out the limiting column 362-2.
[0040] It should be noted that the fixed plate 31 serves as a fixed end, the gear assembly 32, the sliding plate 33 and the rotating assembly 34 serve as a reciprocating mechanism, the scraper 36 is fixed to the sliding plate 33 through the scraper 36, and the scraper 36 is reciprocated in the height direction on the output screen 22 through the overall reciprocating mechanism. At the same time, through the reciprocating process of the scraper 36, when the scraper 36 moves to the abutment column 222, the scraper 362 is pressed by the abutment column 222 to push the limiting column 362-2 into the limiting hole 363-1, so that the scraper 362 is limitedly unfolded and abutted on the output screen 22. When the scraper 36 moves to the push-out column 223, the push-out column 223 enters the limiting hole 363-1 and pushes the limiting column 362-2 out of the limiting hole 363-1, so that the scraper 362 returns to the initial tilt state.
[0041] The output screen 22 light source end of the above-mentioned hazard avoidance lamp 2 cooperates with the central control module and the dynamic display module, and can be adjusted to a certain extent in actual operation. The above-mentioned scraper assembly 3 cooperates with the cleaning and maintenance module, and can be adjusted to a certain extent in actual operation.
[0042] Working principle: In this embodiment, when the hazard lights start to work, the problem of unclear output screen display caused by weather cannot be solved immediately because it is located in a high-speed road. Therefore, in use, the reciprocating mechanism in this embodiment drives the sliding plate to reciprocate, and finally drives the scraper to reciprocate and clean the water droplets, sand or snow on the output screen. When the reciprocating scraper moves to the top, the scraper is expanded by the low pressure of the abutting column and abuts the output screen to move downward and clean the output screen; when the reciprocating scraper moves to the ground end, the scraper is pushed open by the abutting column and restores the initial tilt state of the scraper to prevent stains caused by secondary scraping.
