Description

Technical Field

[0001] This invention is a video surveillance device based on electronic information, belonging to the field of video surveillance technology of electronic information. Background Technology

[0002] The monitoring equipment acts like the eyes of the entire system, converting what it monitors into image signals and transmitting them to the monitors in the control center. Since the camera is at the very front of the system, and it is the one that converts the monitored area into image signals and transmits them to the monitors in the control center, from the perspective of the entire system, the camera is the original signal source of the system.

[0003] Existing electronic information video surveillance equipment can only monitor images visible to the naked eye in real time through the monitoring system. However, it is difficult to monitor micro-changes that occur on the construction site. Therefore, it can only provide safety assurance for the construction site from a single aspect. The installation carrier of the surveillance camera is mostly a single rotating structure, which can only achieve tilting or horizontal rotation in one direction. Moreover, the adjustment mechanism lacks multi-level linkage design, resulting in insufficient angle adjustment accuracy and narrow coverage, making it difficult to adapt to the all-round monitoring needs in complex scenarios. Summary of the Invention

[0004] In view of the shortcomings of existing technologies, the purpose of this invention is to provide a video surveillance device based on electronic information.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: A video surveillance device based on electronic information includes a frame, with movable wheels rotatably connected to both sides of the frame for movement, and steering wheels for steering at the bottom of the frame. The frame is equipped with motors for driving the movable wheels and the steering wheels respectively. The top of the frame is provided with a housing, the housing is provided with a vertically arranged column, one side of the column is provided with a horizontally arranged crossbeam, the top of the crossbeam is provided with a monitoring station, the top opening of the monitoring station is provided with a frustum, the top of the frustum is provided with a monitoring camera, and the monitoring station is provided with an adjustment mechanism for adjusting the angle of the frustum.

[0006] Preferably, the adjustment mechanism includes a turntable rotatably connected to the monitoring station. The monitoring station has a hollow structure. The top of the turntable is provided with a mounting base. The top of the mounting base is rotatably connected to a rotating shaft. The top of the rotating shaft is provided with a connector. The top of the connector is provided with an L-shaped rod movably connected to the frustum.

[0007] Preferably, a worm gear is fitted onto the rotating shaft, and a worm is provided on one side of the worm gear to mesh with it.

[0008] Preferably, a matching bushing is movably sleeved on the rotating shaft and above the worm gear, and a second connector is provided at the top of the bushing and above the first connector. The top of the second connector is provided with an L-shaped rod that is movably connected to the frustum.

[0009] Preferably, a second worm wheel is fitted at the bottom end of the bushing and above the first worm wheel, and a second worm gear meshing with the second worm wheel is provided on one side of the second worm wheel.

[0010] Preferably, a movable sleeve is movably fitted onto the bushing, and a connecting member three is provided at the top end of the movable sleeve. The top end of the connecting member three is provided with an L-shaped rod three that is movably connected to the frustum.

[0011] Preferably, a bearing connected to the mounting base is fitted on the movable sleeve and at the bottom of the connecting member three, and a worm wheel three is fitted at the bottom end of the movable sleeve and above the worm wheel two, and a worm three meshing with the worm wheel three is provided on one side of the worm wheel three.

[0012] Preferably, worm gear one, worm gear two, and worm gear three are each movably connected to the mounting base via bearing seats, and the mounting base is provided with servo motors for driving worm gear one, worm gear two, and worm gear three respectively.

[0013] Preferably, L-shaped rod one, L-shaped rod two, and L-shaped rod three are each movably connected to connector one, connector two, connector three, and the frustum via movable shafts.

[0014] Preferably, the turntable is rotatably connected to the monitoring station via a fixed shaft. A worm gear four is sleeved on the fixed shaft, and a worm four meshes with the worm gear four on one side. A stepper motor for driving the worm four is provided inside the monitoring station.

[0015] The beneficial effects of this invention are: With the cooperation of the moving wheels on both sides of the frame, the steering wheels at the bottom, and the independent drive motor, the equipment can move autonomously and turn flexibly without manual handling. It can quickly adjust the monitoring position, adapt to dynamic monitoring scenarios, and greatly improve the mobility of monitoring coverage.

[0016] The adjustment mechanism adopts a three-stage worm gear linkage design, coupled with servo motor drive, which can precisely adjust the tilt angle of the truncated cone; at the same time, the turntable, through the cooperation of worm gear four and worm four with stepper motor, can achieve 360° horizontal rotation. Combined with the installation of monitoring cameras, it forms all-round monitoring without blind spots, and the adjustment accuracy and coverage are significantly better than traditional equipment.

[0017] The nested design of the rotating shaft, bushing, and movable sleeve, combined with the support of the bearing and bearing seat, reduces the frictional resistance during transmission. The meshing structure of the worm gear has a self-locking function, which can ensure the stability of the position of the adjusted circular platform and the monitoring camera, avoid angular deviation caused by vibration, and ensure the stability of the monitoring image.

[0018] The supporting structure, consisting of the housing, columns, and beams, integrates the monitoring console and adjustment mechanism onto the vehicle frame. The overall layout is compact, ensuring the installation height of the monitoring camera without affecting the mobility of the equipment, making it suitable for various installation and usage scenarios.

[0023] Please see Figure 1-8 The present invention provides a video surveillance equipment technical solution based on electronic information, including a frame 1, with movable wheels 2 rotatably connected to both sides of the frame 1 for movement, and a steering wheel 3 for steering at the bottom of the frame 1, and a motor 4 on the frame 1 for driving the movable wheels 2 and the steering wheel 3 respectively. The frame 1 has a housing 5 on its top, a vertically arranged column 6 on the housing 5, a horizontally arranged crossbeam 7 on one side of the column 6, a monitoring platform 8 on the top of the crossbeam 7, a frustum 9 on the top opening of the monitoring platform 8, a monitoring camera 33 on the top of the frustum 9, and an adjustment mechanism for adjusting the angle of the frustum 9 inside the monitoring platform 8.

[0024] Please see Figure 1-8 The adjustment mechanism includes a turntable 10 rotatably connected to the monitoring station 8. The monitoring station 8 has a hollow structure. The top of the turntable 10 is provided with a mounting base 11. The top of the mounting base 11 is rotatably connected to a rotating shaft 12. The top of the rotating shaft 12 is provided with a connector 13. The top of the connector 13 is provided with an L-shaped rod 14 movably connected to the frustum 9. A worm gear 15 is sleeved on the rotating shaft 12. A worm 16 meshing with the worm gear 15 is provided on one side of the worm gear 15.

The top of the connector 18 is provided with an L-shaped rod 19 movably connected to the frustum 9.

[0025] Please see Figure 1-8 A worm gear 20 is fitted at the bottom of the bushing 17 and above the worm gear 15. A worm 21 meshes with the worm gear 20 on one side. A movable sleeve 22 is movably fitted on the bushing 17. A connector 3 23 is provided at the top of the movable sleeve 22. An L-shaped rod 3 24 is movably connected to the frustum 9 at the top of the connector 3 23. A bearing 25 connected to the mounting base 11 is fitted on the movable sleeve 22 and at the bottom of the connector 3 23. A worm gear 3 26 is fitted at the bottom of the movable sleeve 22 and above the worm gear 20. A worm 3 27 meshes with the worm gear 3 26 on one side.

[0026] Please see Figure 1-8 The worm gear 16, worm gear 21, and worm gear 37 are all movably connected to the mounting base 11 via bearing seats.

[0028] When the tilt angle of the surveillance camera 33 needs to be adjusted, the servo motors 28 on the mounting base 11 independently drive the worm gear 16, worm gear 21, and worm gear 37 to rotate: Worm gear 16 meshes with worm wheel 15, driving shaft 12 to rotate. Through connector 13, it is linked with L-shaped rod 14, pushing frustum 9 to tilt in the corresponding direction. Worm gear 21 meshes with worm wheel 20, driving bushing 17 to rotate. Through connector 2 18, it is linked with L-shaped rod 2 19 to realize the tilt adjustment of frustum 9 in the second direction. Worm gear 3 27 meshes with worm wheel 3 26, driving the movable sleeve 22 to rotate. Through the linkage of connector 3 23 and L-shaped rod 3 24, the tilt adjustment of the frustum 9 in the third direction is completed. The three work together, combined with the flexible connection of movable shaft 29, to achieve precise adjustment of the tilt angle of the monitoring camera 33 in multiple dimensions, and finally achieve all-round video monitoring and acquisition without blind spots.
