Description

Technical Field

[0001] This utility model belongs to the field of unmanned inspection vehicle technology, specifically, it relates to an anti-collision alarm device for unmanned inspection vehicles based on a monocular 3D vision camera. Background Technology

[0002] With the rapid development of industrial automation and intelligence, unmanned inspection vehicles are increasingly widely used in fields such as power, chemical, warehousing, and security. Through autonomous movement, they automatically inspect equipment status, environmental parameters, and area safety, significantly improving inspection efficiency and reducing the labor intensity and safety risks of manual inspections. However, in complex and ever-changing operating environments, unmanned inspection vehicles often face the risk of collisions with obstacles (such as equipment, walls, personnel, and other mobile devices). A collision can not only damage the vehicle itself and interrupt the inspection mission, but also endanger the safety of surrounding personnel and the normal operation of on-site equipment. Therefore, a high-precision, high-reliability collision avoidance warning system has become the core guarantee for the safe operation of unmanned inspection vehicles.

[0003] Existing unmanned inspection vehicles' collision avoidance alarm devices mostly use a single alarm method (such as a fixed-frequency sound alarm or light alarm), which cannot dynamically adjust the alarm intensity or type according to the distance to the obstacle. When the inspection vehicle is far from the obstacle, an overly strong alarm signal can easily interfere with the surrounding staff. When the distance is close, if the alarm signal is not strengthened or switched in time, it may cause the staff to fail to respond quickly, miss the best time to avoid the obstacle, and thus increase the risk of collision.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] To address the limitations of traditional photoelectric detection switches, which can only detect the position of single or multiple points and cannot comprehensively perceive the surrounding environment; the susceptibility of ultrasonic devices to false alarms due to environmental interference, especially in noisy, dusty, or humid environments, where their accuracy and reliability suffer; and the high cost of lidar in challenging environments such as cold storage or direct sunlight, which hinders stable collision avoidance, the basic concept of this invention is as follows: The anti-collision alarm device for unmanned inspection vehicles based on a monocular 3D vision camera includes a mounting housing, a mounting bracket on the side wall of the mounting housing, the mounting bracket being mounted on the unmanned inspection vehicle, a vision camera body being installed inside the mounting housing, and multiple alarm components being installed inside the mounting housing in a circular arrangement. A buzzer is also provided on the top of the mounting housing.

[0006] In a preferred embodiment of the present invention, a circular groove is provided on one side wall of the mounting housing, and a protective housing is also provided inside the mounting housing, and a vision camera body is provided inside the protective housing.

[0007] In a preferred embodiment of this utility model, a servo motor is provided in the inner cavity of the mounting housing, a rotating rod is provided at the output end of the servo motor, a circular mounting plate is provided at the end of the rotating rod away from the servo motor, and an alarm component is provided above the circular mounting plate.

[0008] In a preferred embodiment of this utility model, the buzzer port is provided with a circular housing inside the mounting housing, and the circular housing is located above the alarm component.

[0009] In a preferred embodiment of this utility model, the power of each alarm component is distributed from small to large.

[0010] Compared with the prior art, the present invention has the following advantages: This invention utilizes a monocular 3D vision camera to accurately detect the distance between an unmanned inspection vehicle and objects. A controller links a servo motor to rotate and switch alarm components, allowing for adaptation to different distances and triggering of each component. Sound is emitted through a buzzer in the circular housing, promptly alerting personnel. Its advantages include real-time distance monitoring and dynamic alarm adaptation, improving the accuracy of collision warnings during unmanned inspection vehicle operations, reducing collision risks, ensuring personnel and equipment safety, and optimizing operational safety and efficiency.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0015] like Figures 1 to 4 As shown, the anti-collision alarm device for an unmanned inspection vehicle based on a monocular 3D vision camera includes a mounting housing 1, a mounting bracket 2 on the side wall of the housing 1, and the mounting bracket 2 mounted on the unmanned inspection vehicle. The vision camera body 5 is housed within the inner cavity of the housing 1, and multiple alarm components 9 are also arranged circumferentially within the inner cavity. A buzzer 11 is located at the top of the housing 1. This device uses the monocular 3D vision camera to accurately detect the distance between the unmanned inspection vehicle and objects. A controller links a servo motor 6 to rotate and switch the alarm components 9, allowing for different alarm components 9 to be adapted to different distances and triggered accordingly. Sound is emitted through the buzzer 11 on the circular housing 10, promptly alerting personnel. Its advantages include real-time distance monitoring and dynamic alarm adaptation, improving the accuracy of anti-collision warnings during unmanned inspection vehicle operations, reducing collision risks, ensuring the safety of personnel and equipment, and optimizing operational safety and efficiency. In a specific embodiment, a circular slot 3 is provided on one side wall of the mounting housing 1, and a protective housing 4 is also provided inside the mounting housing 1. The vision camera body 5 is disposed inside the protective housing 4. In this configuration, the specific installation position of the vision camera body 5 is determined.

[0016] Furthermore, a servo motor 6 is installed inside the housing 1, a rotating rod 7 is installed at the output end of the servo motor 6, a circular mounting plate 8 is installed at the end of the rotating rod 7 away from the servo motor 6, and an alarm component 9 is installed above the circular mounting plate 8. In this configuration, the specific installation position of the alarm component 9 is determined.

[0017] Furthermore, a circular housing 10 is provided inside the mounting housing 1 within the buzzer port 11, and the circular housing 10 is located above the alarm component 9. In this configuration, the specific installation position of the circular housing 10 is determined.

[0018] Furthermore, the power of each alarm component 9 is distributed from low to high. In this setup, the relationship between each alarm component 9 is determined.

[0019] The implementation principle of the anti-collision alarm device for unmanned inspection vehicles based on a monocular 3D vision camera in this embodiment is as follows: First, when the vehicle approaches the object to be impacted, the vision camera body 5 can detect the distance between the vehicle and the object through the circular slot 3 opened on the mounting housing 1. When the distance is detected, it can transmit the information to the servo motor 6 through the controller, so the servo motor 6 can rotate the rod 7. When the rod 7 rotates, it can drive the circular mounting plate 8 to rotate. When the circular mounting plate 8 rotates, it can drive the alarm component 9 to change position. Therefore, different alarm components 9 can be replaced to the bottom of the circular housing 10 according to the distance between the vehicle and the object. At the same time, the alarm component 9 can be controlled to operate. Therefore, the alarm component 9 can emit a sound, and the sound can be transmitted to the circular housing 10. Therefore, the sound can be transmitted out from the buzzer 11, thus alerting the staff.
