Description

Technical Field

[0001] This utility model relates to the field of safety monitoring device technology, specifically to an AR event site safety monitoring device. Background Technology

[0002] With the booming development of augmented reality (AR) technology, its application in various events is becoming increasingly widespread, from large-scale commercial exhibitions to immersive art exhibitions, from interactive experience projects in theme parks to practical activities in the field of education and training. AR technology, with its unique virtual-real fusion characteristics, brings participants an unprecedented novel experience. However, at AR event sites, safety issues are gradually becoming a challenge that cannot be ignored. On the one hand, participants are immersed in AR virtual scenes, and their attention is highly focused on virtual information, which greatly reduces their ability to perceive the surrounding real environment. For example, when using AR navigation to tour an exhibition, participants may ignore obstacles in front of them because they are staring at the device screen, which may lead to collision accidents.

[0003] On the other hand, AR events are often crowded, and the simultaneous operation of a large number of AR devices can lead to network congestion. This not only affects the smoothness of the AR experience but may also cause devices to lag, crash, or malfunction, posing safety hazards. In addition, in the event of emergencies such as fires or earthquakes, the difficulty of evacuation will increase significantly because participants are immersed in the virtual world. Traditional security monitoring systems are unable to respond to these problems quickly and effectively. To ensure the safety of people at AR events and to ensure the smooth running of the events, we propose an AR event site safety monitoring device. Utility Model Content

[0033] Structural Description:

[0034] Working support plate 1: The working support plate is the basic support component of the entire device. It is usually made of metal or high-strength plastic to ensure structural stability. The equidistant fixing connection holes 2 on the rear side are used to install the device on the support structure such as walls and columns. It can be fixed by bolts, expansion screws and other connectors to adapt to different installation scenarios. The equidistant sliding holes 15 on the front side provide a track for the installation and position adjustment of the connecting support rod. It cooperates with the connecting locking boss to realize the installation and disassembly of the device. The locking link support platform 7 on the front bottom is used to install the locking connection spring and locking slide plate to provide support for the locking fixing components.

[0035] Connecting support rod 3: The connecting support rod serves to connect the working support plate and the angle adjustment component. It is generally made of metal rod and has a certain strength and rigidity. The connecting locking boss 4 on the rear bottom surface cooperates with the sliding hole of the working support plate. The locking sliding hole on the inner side is used to install the locking slide plate to achieve a detachable connection with the working support plate. The motor support platform 9 on the front side is used to fix the longitudinal drive motor and provide an installation position for the longitudinal angle adjustment component. The rotating hole 16 on the front side provides rotation support for the internal rotating shaft and is a key connection part of the longitudinal angle adjustment component.

[0036] AR Spherical Surveillance Camera 12: The AR spherical surveillance camera is the core component for realizing the monitoring function. It has high-definition shooting and AR technology-related image processing capabilities. Through multi-angle adjustment, it can collect real-time images of the event site, monitor the behavior of participants and the status of on-site equipment, promptly detect safety hazards and abnormal situations, and transmit the collected information to monitoring personnel or related systems for processing.

[0037] Connecting locking boss 4: The connecting locking boss is usually made of metal and its shape is adapted to the sliding hole 15 of the working support plate 1 to ensure smooth sliding. The locking sliding hole on its inner side is a key structure, providing a sliding track for the locking slide plate 5 so that the two can cooperate to achieve positioning and fixation.

[0038] Positioning slide plate 5: The positioning slide plate is generally made of wear-resistant engineering plastic or metal. Its shape is designed to facilitate sliding between different parts. It slides in the positioning slide hole at the bottom of the positioning link support platform 7, the front bottom of the working support plate, and the bottom of the connecting positioning boss. Through cooperation with the positioning link spring 6, it plays a role in quick positioning and fastening during device installation.

[0039] The locking connection spring 6 is a compression spring made of spring steel with good elasticity. It is fixed inside the locking link support platform 7, with one end abutting against the locking slide plate 5, providing continuous thrust to the locking slide plate, so that the connecting locking boss 4 is tightly connected to the working support plate 1, ensuring that the entire device is installed stably.

[0040] Longitudinal drive motor 8: Longitudinal drive motors are mostly small DC motors or stepper motors, characterized by small size and high torque. Their housings are generally made of metal, which serves to protect the internal mechanism and dissipate heat. The output shaft is specially processed and tightly connected to the internal rotating shaft 17 to provide power for longitudinal rotation.

[0041] Longitudinal rotating rod 10: The longitudinal rotating rod is made of metal material and has a certain length and strength. The motor mounting slot 18 at the front end is used to install the horizontal drive motor 11. The rotating rod rotating connecting boss 14 on the top surface of the front end is the key part connected to the horizontal rotating rod 13. The rear end is fixed to the internal rotating shaft 17. Under the drive of the motor, the longitudinal angle adjustment of the AR spherical monitoring camera 12 is realized.

[0042] Internal rotating shaft 17: The internal rotating shaft is usually made of metal with a smooth surface. It forms a rotating fit with the side rotating hole 16. One end is fixed to the output shaft of the longitudinal drive motor 8, and the other end is fixed to the longitudinal rotating rod 10. Under the drive of the motor, the longitudinal rotating rod is rotated, thereby realizing the change of the longitudinal angle of the AR spherical monitoring camera.

[0043] Lateral drive motor 11: The lateral drive motor also mostly adopts a small DC motor or stepper motor, which is installed in the motor mounting slot 18 at the front end of the longitudinal rotating rod 10. Its output shaft is fixedly connected to the connecting turntable 19 at the bottom of the lateral rotating rod 13 to provide power for lateral rotation, so as to realize the lateral angle adjustment of the AR spherical monitoring camera 12.

[0044] Horizontal rotating rod 13: The horizontal rotating rod is generally made of metal. The connecting turntable 19 of the top and bottom surfaces is a key structure. The bottom connecting turntable is connected to the output shaft of the horizontal drive motor, and the top connecting turntable is rotatably connected to the rotating rod rotating connecting boss 14. The AR spherical monitoring camera 12 is fixed on the bottom front surface, and the camera is driven by the motor to achieve horizontal angle rotation.

[0045] Working principle: When this utility model is needed for installation, the connecting locking boss 4 on the connecting support rod 3 is aligned with the sliding hole 15 on the front side of the working support plate 1 and inserted. At this time, the locking connecting spring 6 pushes the locking slide plate 5, causing it to slide within the locking connecting support platform 7, the front bottom surface of the working support plate, and the locking sliding hole at the bottom of the connecting locking boss, completing quick positioning and fixing, and realizing the installation of the device. If the position needs to be adjusted, the locking slide plate can be squeezed to overcome the elasticity of the locking connecting spring, causing the connecting locking boss to slide within the sliding hole and be re-fixed to the appropriate position. When it is necessary to adjust the longitudinal angle of the AR spherical monitoring camera 12, the longitudinal drive motor 8 is started, and its output shaft drives the internal rotating shaft 17 to rotate within the side rotating hole 16. The longitudinal rotating rod 10, fixed on the outside of the moving shaft, rotates accordingly, thereby adjusting the longitudinal angle of the AR spherical monitoring camera. When adjusting the lateral angle, the lateral drive motor 11 starts, and its output shaft drives the bottom connecting turntable 19 to rotate, which in turn drives the lateral rotating rod 13 to rotate around the connection point at the front of the longitudinal rotating rod 10, thereby adjusting the lateral angle of the AR spherical monitoring camera. Through bidirectional adjustment, all-round monitoring is achieved. After the AR spherical monitoring camera is turned on, it continuously collects images of the event site. Utilizing its flexible angle adjustment function, it monitors participants who are distracted while immersed in the AR scene. Once it detects safety hazards such as participants colliding with obstacles or abnormal situations such as equipment malfunctions on site, it can issue early warning signals in a timely manner.
