Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted sensor technology, and more specifically to a vehicle-mounted beyond-line-of-sight obstacle detection device. Background Technology

[0002] The core advantage of the vehicle-mounted beyond-line-of-sight obstacle detection device lies in breaking through the limitations of traditional environmental perception. Through the deep fusion of millimeter-wave radar and a steerable wide-angle camera, it significantly improves the reliability of detection in complex scenarios. Millimeter-wave radar maintains stable detection capabilities in low-visibility environments such as rain, fog, and smoke, with strong penetration and is not affected by lighting conditions, effectively compensating for the failure defects of traditional optical sensors in adverse weather conditions. Meanwhile, the wide-angle camera array actively eliminates blind spots such as curves and slopes through a dynamic field-of-view compensation mechanism. Combined with the spatial reference calibration of the high-precision positioning module, it achieves absolute position locking of obstacles. The multi-source fusion algorithm embedded in the device performs spatiotemporal collaborative processing of radar point clouds and visual data, greatly reducing the false alarm rate and solving the problem of insufficient reliability of single sensors due to environmental interference.

[0003] The shortcomings of existing technologies include: traditional camera solutions have limited line of sight and are heavily dependent on lighting conditions, with their detection capabilities dropping sharply in rain and fog; lidar, while highly accurate, is expensive and its performance degrades significantly in dusty, rainy, or snowy environments, and it is difficult to penetrate obstacles; ultrasonic radar is limited to short-range detection; in addition, early systems often lacked effective multi-sensor spatiotemporal registration mechanisms, leading to isolated analysis of radar and camera data, which can easily result in missed judgments or contradictory decisions; and mechanical structures generally suffer from weak shock resistance and difficult maintenance, making it difficult to meet the long-term reliability requirements of the vehicle environment. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a vehicle-mounted beyond-line-of-sight obstacle detection device to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vehicle-mounted beyond-line-of-sight obstacle detection device, comprising a vehicle body, and further comprising: a fixed mounting frame, a radar signal processing module, and a millimeter-wave radar. The fixed mounting frame is fixedly mounted on the bottom of the vehicle body, the radar signal processing module is fixedly mounted on the inner side of the fixed mounting frame, and the millimeter-wave radar is fixedly mounted on the inner side of the fixed mounting frame.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The vehicle-mounted beyond-line-of-sight obstacle detection device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Reference Figures 1 to 4 This utility model provides a vehicle-mounted beyond-line-of-sight obstacle detection device, including a vehicle body 1, and further including: a fixed mounting frame 2, a radar signal processing module 3, and a millimeter-wave radar 4. The fixed mounting frame 2 is fixedly installed at the bottom of the vehicle body 1, the radar signal processing module 3 is fixedly installed inside the fixed mounting frame 2, and the millimeter-wave radar 4 is fixedly installed inside the fixed mounting frame 2.

[0020] The fixed installation frame 2 includes a frame body 201, which provides mechanical protection against impact and deformation, ensuring the safety of internal precision components under harsh road conditions. The 203 installed on it adopts a quick-release design for easy maintenance and replacement. A steerable wide-angle camera 202 is symmetrically fixedly installed on both sides of the frame body 201. Fifteen evenly distributed mounting bracket doors 203 are fixedly installed at one end.

[0021] The millimeter-wave radar 4 includes a radar radome 401, a radar body 402 movably mounted on the lower side of the radar radome 401, a die-cast base plate 403 fixedly mounted on the bottom of the radar body 402, an integrated circuit 404 fixedly mounted on the upper side of the die-cast base plate 403, a radar PCB board 405 fixedly mounted on the upper side of the integrated circuit 404, and an independent connector 406 fixedly mounted on the other end of the radar body 402. This design is beneficial for waterproofing and dustproofing, and reduces wind noise interference to the signal. Because the radar surface is covered with a wave-transparent material and is made of die-cast aluminum alloy, it also has heat dissipation and electromagnetic shielding functions, which can prevent electromagnetic interference from vehicle electrical appliances.

[0022] Among them, the millimeter-wave radar 4 is fixedly installed inside the fixed mounting frame 2, the radar signal processing module 3 is fixedly installed on the right side of the millimeter-wave radar 4, the integrated circuit 404 is fixedly installed inside the radar body 402, and the radar PCB board 405 is installed inside the radar body 402.

[0023] The independent connector 406 is fixedly installed in the frame body 201, and a high-precision positioning module 204 is fixedly installed at the bottom of the mounting frame door 203, which is conducive to continuously outputting the vehicle's own accurate geographical coordinates.

[0024] The working principle of this utility model is as follows: When the vehicle is running, the fixed mounting frame 2 at the bottom of the vehicle body provides stable support for the whole system. The steerable wide-angle cameras 202 symmetrically distributed on both sides dynamically scan the surrounding environment. When the vehicle is turning, the viewing angle is actively adjusted to eliminate blind spots. At the same time, the millimeter-wave radar 4 continuously emits detection beams through the radar body 402 under the protection of the radome 401, penetrating rain, fog or complex environments to capture obstacle signals beyond the line of sight range.

[0025] The integrated circuit 404 on the die-cast base plate 403 inside the radar and the radar PCB board 405 process the echo in real time, converting the distance, speed and orientation information of obstacles into digital signals, and transmitting them to the radar signal processing module 3 through an independent connector 406. At the same time, the high-precision positioning module 204 at the bottom of the mounting bracket 203 continuously outputs the vehicle's own precise geographical coordinates.

[0026] The radar signal processing module 3 integrates the visual data collected by the steerable wide-angle camera 202 and the spatial coordinates of the obstacle positioning module generated by the millimeter-wave radar 4, and transmits them to the vehicle control system in real time to trigger automatic braking response, thereby achieving all-weather beyond-line-of-sight safety protection.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
