[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-6In this embodiment, a camera for detecting abnormal behavior of a bus includes a plurality of camera bodies 1 and at least one mounting base 2, for example, two mounting bases 2. A camera lens is mounted on the surface of the camera body 1. In this embodiment, two mounting bases 2 are mounted on the front and rear of the bus roof by fastening screws.

[0030] The mounting base 2 is provided with a plurality of mounting holes for fastening screws to pass through.

[0031] It should be noted that the system of cameras used to detect abnormal behavior in public transportation usually includes the following components:

[0032] Camera: used to capture real-time video data inside the bus.

The entire process is carried out in real time, and abnormal situations in the bus can be discovered and handled in a timely manner, improving passengers' sense of security.

[0037] The mounting seat 2 in this embodiment is provided with a shock absorbing mechanism for buffering the vibration generated by the running of the bus.

[0038] It should be noted that the shock absorbing mechanism includes a shock absorbing spring 3 installed at the bottom of the mounting seat 2, a connecting seat 5 is installed at the bottom of the shock absorbing spring 3, a plurality of resistance increasing sleeves 6 distributed in an annular shape and at equal distances are installed on the top of the connecting seat 5, a plurality of resistance increasing rods 7 distributed in an annular shape and at equal distances and corresponding to the resistance increasing sleeves 6 are installed at the bottom of the mounting seat 2, a socket 8 is installed at the bottom of the connecting seat 5, and a buffer shock absorbing sleeve 9 is installed on the inner wall of the socket 8. Among them, the resistance increasing rod 7 passes through the resistance increasing sleeve 6, is closely attached to the resistance increasing sleeve 6, and extends through to the bottom of the connecting seat 5.

[0039] A spliced ​​cross bar 10 is installed between the shock absorbing mechanisms in this embodiment, a resistance increasing groove is opened on the outside of the resistance increasing rod 7, a limiting block is installed at the bottom end of the resistance increasing rod 7, and a bellows rubber protective sleeve 4 located outside the shock absorbing spring 3 is installed between the mounting seat 2 and the connecting seat 5.

[0040] The bellows rubber protective sleeve 4 is a rubber sleeve that can be stretched and contracted to protect the shock absorbing spring 3 to avoid rust.

[0041] One end of the splicing cross bar 10 is provided with a docking slot and the other end is integrally connected with a docking plug corresponding to the docking slot to facilitate assembly and docking between the splicing cross bars 10. The two ends of the splicing cross bar 10 are respectively inserted into two buffer shock-absorbing sleeves 9.

[0042] The buffer shock-absorbing sleeve 9 is a rubber shock-absorbing sleeve that fits tightly with the splicing cross bar 10. When the splicing cross bar 10 is assembled and spliced, the docking plug on one end of the splicing cross bar 10 is inserted into the docking slot on the other splicing cross bar 10.

[0043] The splicing cross bar 10 is provided with a plurality of adjustment components for installing and adjusting the camera body 1 to adjust the camera orientation. It should be noted that the adjustment components include a plurality of movable collars 11 slidably sleeved on the outside of the splicing cross bar 10, and the top of the movable collar 11 is threadedly connected with a fastening screw 12 in contact with the splicing cross bar 10.

[0044] The movable sleeve ring 11 is provided with a through hole having the same diameter as the splicing cross bar 10 .

[0045] Among them, a ball head seat 13 is fixedly installed at the bottom of the movable ring 11, a magnetic sleeve 14 is installed inside the ball head seat 13, a ball head 15 is wrapped and rotated inside the magnetic sleeve 14, an electromagnet 16 in contact with the magnetic sleeve 14 is embedded on the top of the ball head 15, and the bottom of the ball head 15 is installed and fixed to the camera body 1 by fastening screws.

[0046] The magnetic sleeve 14 is a magnetic material that can be magnetically adsorbed.

[0047] The ball head seat 13 and the magnetic suction sleeve 14 are both hollow semi-spheres, and the ball head 15 is a spherical body and is inseparable from the magnetic suction sleeve 14 .

[0048] The splicing crossbar 10 in this embodiment is also provided with a wiring assembly for a plurality of camera bodies 1 to be wired and connected uniformly.

[0049] It should be noted that the wiring assembly includes a plurality of equally spaced threading holes 17 formed at the bottom of the splicing cross bar 10 and a connecting wire hole 18 formed on the socket 8 and connected to the splicing cross bar 10 .

[0050] The working principle of the above embodiment is:

[0051] The splicing cross bar 10 is assembled and spliced ​​according to the length of the bus compartment to be equal to the length of the bus compartment, and the spliced ​​splicing cross bar 10 is inserted between the two buffer shock-absorbing sleeves 9, and then the two mounting seats 2 are respectively fixed to the middle of the front and rear of the bus compartment roof by fastening screws;

[0052] By moving the movable sleeve 11 outside the splicing cross bar 10, each camera body 1 can be driven to move, and then the distance between each camera body 1 can be adjusted according to the monitoring detection range of the camera body 1. The adjusted movable sleeve 11 can be fastened and fixed by hand-held rotation and tightening the fastening screw 12 to ensure the fixedness of the camera body 1 after adjustment, avoiding the traditional method of drilling holes at multiple points in the car to install the camera body 1 one by one. After the adjustment of the distance between each camera body 1 is completed to ensure that the entire range in the bus car can be detected, the camera body 1 can be universally adjusted by driving the ball head 15 in the magnetic suction sleeve 14 by holding the camera body 1, so as to facilitate the adjustment of the camera angle of each camera body 1 according to the detection camera needs. At the same time, after the angle adjustment is completed, the set electromagnet 16 is energized to adsorb and fix the magnetic suction sleeve 14, so that the ball head 15 can be fixed after adjustment, thereby realizing the angle adjustment and fixation of the camera body 1, improving the adjustment efficiency, ensuring the unified horizontal line of the detection camera angle, and improving the camera detection effect;

[0053] In addition, after the camera body 1 is installed and adjusted, the wiring harnesses on each camera body 1 can be inserted through the threading hole 17 and stored in the splicing cross bar 10 for protection to prevent the wiring harnesses from being exposed. At the same time, the wiring harnesses pass through the connecting wire hole 18 to connect with the bus, effectively ensuring the aesthetics and protection effect of the installation;

[0054] At the same time, when the bus vibrates during driving, the shock-absorbing spring 3 elastically stretches and contracts, while driving the resistance-increasing sleeve 6 on the connecting seat 5 to move synchronously with the resistance-increasing rod 7 to increase the resistance by friction, thereby achieving an integrated shock-absorbing effect. At the same time, the buffer shock-absorbing sleeve 9 effectively absorbs and buffers the loading equipment on the splicing cross bar 10, ensuring a unified shock-absorbing effect on each camera body 1, achieving the uniformity of the picture of the camera body 1, and improving the detection and video effect.

[0055] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
