Description

Technical Field

[0001] This utility model relates to the field of traffic safety technology, and in particular to a vehicle safety warning system for long uphill road sections. Background Technology

[0002] In mountainous and hilly areas with complex terrain, long uphill sections are a common design feature in highway construction to overcome elevation differences. When large, heavy-duty vehicles travel on long uphill sections, their climbing speed is significantly reduced due to their large load capacity and limited power, creating a large speed difference with vehicles traveling at normal speeds and disrupting normal traffic flow.

[0003] Due to insufficient lighting on some long uphill sections of highways, drivers' visibility is obstructed when driving at night. When they spot a vehicle ahead, the distance between the two vehicles is often too close, leaving drivers with very little time to react and brake, which can easily lead to traffic accidents. However, traditional warning measures, such as warning signs and reflective road studs, are much less effective in inclement weather and cannot transmit vehicle driving information in real time, thus failing to reduce the risk of rear-end collisions.

[0004] Therefore, there is an urgent need for a warning system to ensure driving safety on long uphill sections, in order to reduce the risk of rear-end collisions on such sections. Utility Model Content

The power supply module 5 provides power to the control module 1, the speed measurement module 2, the image acquisition module 3, and the warning module 4 to ensure the normal operation of these modules.

[0018] In one embodiment of this utility model, the control module 1 includes a microcontroller 101, a CPLD 102, and a serial port unit 103. The microcontroller 101 is connected to the CPLD 102, the serial port unit 103, the warning module 4, and the power module 5. The CPLD 102 is connected to the warning module 4 and the power module 5. The serial port unit 103 is connected to the speed measurement module 2, the image acquisition module 3, and the power module 5. The serial port unit 103 includes two types: an R485 serial port and a CAN serial port, to support the speed measurement module 2 and the image acquisition module 3 with different serial port types, ensuring that the driving speed measured by the speed measurement module 2 and the driving image acquired by the image acquisition module 3 can be transmitted to the microcontroller 101.

[0019] In one embodiment of this utility model, the microcontroller 101 processes the driving image and identifies the vehicle and vehicle type in the driving image. The processing of the driving image by the microcontroller 101 can be referred to the vehicle driving image recognition device with publication number CN108241835A in the prior art, and will not be described in detail here.

[0020] In one embodiment of this utility model, the speed measurement module 2 includes a radar, which is connected to a serial port unit 103 and a power module 5. The radar is used to measure the driving speed of the vehicle and transmits the driving speed to the microcontroller 101 through the serial port unit 103.

[0021] In one embodiment of this utility model, the warning module 4 includes a display screen 401 and an audible and visual alarm 402; a microcontroller 101 is connected to the display screen 401 and the audible and visual alarm 402, a CPLD 102 is connected to the display screen 401 and the audible and visual alarm 402, and a power module 5 is connected to the display screen 401; the audible and visual alarm 402 includes a warning light 4021 and a broadcast unit 4022; the microcontroller 101 is connected to the warning light 4021 and the broadcast unit 4022, and the CPLD 102 is connected to the warning light 4021 and the broadcast unit 4022.

[0022] See Figure 8-10 As shown, in one embodiment of this utility model, the display screen 401 is positioned on the side closest to the long uphill section of the road, so that the driver can clearly see the content on the display screen 401.

These conditions are determined by the control module 1 through processing the driving images acquired by the image acquisition module 3. Figure 8 The display shows that there are no vehicles in front of the vehicle on the long uphill section (driving condition A). At this time, the display screen 401 displays a safe travel slogan, and the sound and light alarm 402 does not take any action. Figure 9 The scenario depicts a vehicle ahead of a target vehicle on a long uphill section (driving condition B). At this point, control module 1 generates a warning signal indicating whether the vehicle is moving slowly, based on the speed measured by speed measurement module 2 and the vehicle type (determined by processing the driving image acquired by image acquisition module 3). This warning signal controls display screen 401 to show the vehicle's speed, controls warning light 4021 to flash, and broadcast unit 4022 to play a warning voice message, sending a strong warning signal to the target vehicle. This ensures the driver of the target vehicle can promptly notice and take deceleration measures, reducing the risk of rear-end collisions on long uphill sections.
