[0030] Example 1

[0031] like Figure 1-6 As shown, a blind spot vehicle distance warning device for a tunnel entrance in this embodiment includes a set of camera components 1, a display component 2 and an information processing device 3 arranged in each lane;

[0032] The camera assembly 1 is arranged on the surface of the tunnel entrance body 4 and the camera assembly 1 is arranged outside the tunnel construction limit 5; the camera assembly 1 is arranged on the verified tunnel body above the tunnel entrance lane and at a reasonable position outside the tunnel construction limit 5; the above arrangement ensures that the camera assembly 1 can capture the image of the vehicle entering the tunnel lane without hindrance, and provides an accurate data source for subsequent vehicle distance calculation and information processing;

[0033] The display component 2 is arranged near the camera component 1, and the two cannot block each other and can capture vehicles traveling in the lane; after receiving the vehicle information processed by the information processing device 3, the corresponding warning statement and the current safe braking distance are immediately displayed on the display component 2 to remind the driver in time.

[0034] The display component 2 is used to display the vehicle image captured by the camera component 1 and the vehicle distance information calculated by the information processing device 3.

[0035] The information processing device 3 is installed near the camera assembly 1 and the display assembly 2 and is located outside the tunnel construction limit 5; it is responsible for receiving the image data transmitted by the camera assembly 1, performing calculations and processing, and then sending the results to the display assembly 2 for display.

[0036] In the present application, the camera component 1 records the instantaneous speed of the passing vehicle at the moment the vehicle passes, and sends the data in the form of a signal to the information processing device 3 to calculate the vehicle distance that safely meets the parking sight distance in extreme emergency braking conditions, and displays the corresponding warning statement and the current safe braking distance on the display component 2 to promptly remind the driver.

[0037] In the present application, a blind spot distance warning device for a tunnel entrance is provided with a lane camera 11 and a corresponding LED display screen 21 for each lane at the tunnel entrance, so as to realize real-time monitoring and warning of the blind spot distance of the tunnel entrance, and improve driving safety and driving experience. When a vehicle is about to enter the tunnel entrance, the lane camera 11 records the instantaneous speed of the passing vehicle when passing through, and transmits the vehicle information to the information processing device 3, and then uses the information processing device 3 to calculate the safe vehicle distance that meets the parking sight distance in the case of extreme emergency braking, and then transmits the information to the lane LED display screen 21, and displays the warning information on the LED display screen 21, reminding the vehicle to pay attention to driving safety and the current safe distance for braking.

[0038] Specifically, each group of display components 2 is within a range of 1 m from the corresponding camera component 1;

[0039] Each group of information processing devices 3 is installed near the camera assembly 1 and the display assembly 2 within a range of 1 m.

[0040] The above-mentioned position relationship setting not only ensures the immediacy and consistency of image acquisition and display, but also reduces errors. The driver can quickly match the information on the display component 2 with the real-time image captured by the camera component 1, so as to more accurately judge the driving conditions. The closer distance reduces the delay and error of data transmission, ensures the accuracy and real-time nature of the information, which is particularly important for traffic environments that require rapid response and judgment.

[0041] Example 2

[0042] Based on Example 1, please refer to Figure 1 The camera assembly 1 is a speed measuring camera that records the instantaneous speed of a passing vehicle. The speed measuring camera uses advanced image processing technology to accurately measure the vehicle speed and ensure the accuracy of the data. In addition to taking vehicle images, the speed measuring camera can also record speed data at the same time, realizing functional integration and optimization.

[0043] The camera assembly 1 sends the collected data in the form of a signal to the information processing device 3 to calculate the vehicle distance that satisfies the parking sight distance safely in the case of extreme emergency braking, and displays the corresponding warning statement and the current safe braking distance on the display assembly 2. The display assembly 2 displays the warning statement and the safe braking distance, so that the driver can intuitively understand the current driving safety status.

[0044] In this embodiment, a speed measuring camera is used as the camera component 1, and the speed data is combined to calculate the vehicle distance and display the warning information, which can further improve the accuracy and practicality of the blind spot vehicle distance warning device at the tunnel entrance; the above design can not only provide the driver with a more comprehensive and accurate driving safety warning, but also improve the driver's vigilance and reduce the risk of traffic accidents.

[0045] Furthermore, the information processing device 3 has a built-in wireless signal transceiver component 31 and an embedded single-chip microcomputer 32, which immediately processes the information signal sent by the camera component 1, and interprets the current vehicle speed through the embedded single-chip microcomputer 32 to determine whether the lane LED display screen 21 needs to be started.

[0046] In this embodiment, the information processing device 3 has a built-in wireless signal transceiver component 31, which enables wireless data transmission between the camera component 1 and the information processing device 3; the wireless connection method not only simplifies the wiring of the system, but also improves the flexibility and reliability of data transmission. The embedded single-chip microcomputer 32 as the core of the information processing device 3 has powerful data processing and judgment capabilities; it can quickly process the information signal sent by the camera component 1, and judge whether the lane LED display screen 21 needs to be started according to the current vehicle speed.

[0047] Furthermore, the display component 2 is an LED display screen 21; the LED display screen 21 is an ideal choice for the blind spot distance warning device at the tunnel entrance due to its high brightness, high definition, low power consumption and long life. It can display the vehicle image captured by the camera component 1, the vehicle speed information and the key information such as the safe braking distance calculated by the information processing device 3 in real time.

[0048] According to the actual speed and safe distance of each vehicle, the LED display screen 21 can display personalized warning information; the personalized warning method can more directly remind the driver to pay attention to driving safety and improve the driver's alertness and reaction speed.

[0049] The utility model is a blind spot vehicle distance warning device for a tunnel entrance. When a vehicle passes through a road section photographed by a lane camera 11, the lane camera 11 sends information to an information processing device 3, and warns the driver of driving safety and safe braking distance on an LED display screen 21. At the same time, when the vehicle passes, the information processing device 3 receives the vehicle's driving speed through a wireless signal transceiver component 31, and reads the current vehicle speed through an embedded single-chip microcomputer 32. If the current vehicle speed exceeds the speed required by the current speed limit, the LED display screen 21 is activated through the wireless signal transceiver component 31. If activated, the vehicle information is sent to the LED display screen 21 in a timely manner, and the driver is warned of driving safety and safe braking distance on the LED display screen 21. After the vehicle receives the information from the LED display screen 21, it can avoid the occurrence of safety accidents and protect the health and safety of the driver's life and property.

[0050] The present invention is further described in conjunction with the embodiments, but the present invention is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
