Description

Technical Field

[0001] This invention relates to the field of display camera devices, and more particularly to an LED screen camera system. Background Technology

[0002] LED screens are widely used in video conferencing, which requires cameras to capture and transmit video content. Centering the camera is a crucial requirement. Traditionally, there are two methods to achieve this: one is to use a movable tripod with the camera placed in front of the LED screen. This method requires moving the camera and tripod each time it is used, as well as frequently unplugging and plugging power, control, and signal cables, which can easily cause system failures and is unstable. The other method is to fix the camera on a lifting rod, which is then installed on the ceiling. This method makes the camera prone to shaking, can easily jam cables during lifting, requires a certain ceiling height, and is also unstable.

[0003] Based on this, this application proposes an LED screen camera system that is convenient and stable to use, avoids cable jamming, and avoids frequent cable plugging and unplugging. Summary of the Invention

[0004] The present invention aims to provide an LED screen camera system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An LED screen camera system includes a mounting frame connected to a housing fixing plate, which in turn connects to a fixed display screen. Several sets of fixed display screens are provided. An X-axis mounting plate is connected to the mounting frame, and an X-axis moving module is connected to the X-axis moving module. The output end of the X-axis moving module is connected to a first Y-axis moving module and a second Y-axis moving module. The first and second Y-axis moving modules are respectively connected to a first moving frame and a second moving frame. A fixed housing is connected to the first moving frame, and a pan-tilt camera is connected to the fixed housing. A mobile display screen is connected to the second moving frame. An electrical component mounting plate is also connected to the mounting frame, and an electrical control unit is connected to the mounting frame. The electrical control unit includes a PLC mainboard connected to the electrical component mounting plate. A motor driver is connected to the electrical component mounting plate. A switching power supply and a mainboard switching power supply are connected to the electrical component mounting plate, and the mainboard switching power supply is electrically connected to the PLC mainboard. A terminal block and a smart remote control switch are also connected to the electrical component mounting plate.

[0007] Preferably, the output end of the X-axis moving module is connected to a motion slide, and the first Y-axis moving module and the second Y-axis moving module are connected to the motion slide.

[0008] Preferably, the X-axis mounting plate is connected to an auxiliary rail, the auxiliary rail is connected to an auxiliary slide, the auxiliary slide is connected to an auxiliary sliding plate, and the first Y-axis moving module is connected to the auxiliary sliding plate.

[0009] Preferably, the X-axis mounting plate is connected to a positioning block, and the positioning block is detachably connected to the housing fixing plate.

[0010] Preferably, the mounting bracket is connected to a mounting frame, and the electrical component mounting plate is connected to the mounting frame.

[0011] Preferably, the first movable frame includes a connecting plate and an auxiliary plate. The auxiliary plate is connected to the output end of the first Y-axis movable module. The auxiliary plate is connected to a reinforcing plate, and there are two sets of reinforcing plates. The connecting plate is connected to the reinforcing plate, and the fixed box is connected to the connecting plate. The structure of the second movable frame is the same as that of the first movable frame. The connection method between the movable display screen and the second movable frame is the same as the connection method between the fixed box and the first movable frame.

[0012] Preferably, the mounting bracket is connected to a stainless steel protective cover.

[0013] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0014] (1) This technical solution uses a hidden camera to complete the shooting. The camera can be hidden behind the LED screen. The position adjustment of the camera and the mobile display screen is completed by the X-axis moving module, the first Y-axis moving module and the second Y-axis moving module. When the camera needs to work, the mobile display screen is automatically hidden behind the large screen, and the camera moves to the original position of the mobile display screen to shoot. When the large screen needs to be displayed as a whole, the mobile display screen is spliced ​​with the fixed display screen, and the camera is hidden behind the large screen without affecting the overall display of the large screen. It avoids the situation of unstable image acquisition caused by frequent plugging and unplugging of power cords, control lines, etc., and the moving distance is not large. It can also effectively avoid the cable jamming during the movement. The movement is stable and there is no need to frequently plug and unplug cables, which greatly improves the stability of the system. At the same time, there is no need to connect to the ceiling through the lifting rod, which improves the applicability of the system. It can give full play to the display advantages of the LED screen and realize the integration of camera, display and control. It has a very high degree of integration, stability, scientificity and advancement.

[0015] (2) The first moving frame of this technical solution has a relatively wide moving distance along the first Y-axis moving module. Therefore, the first Y-axis moving module is also connected to the auxiliary sliding plate. The auxiliary track makes the force of the first Y-axis moving module balanced, avoiding the situation where the cable of the first Y-axis moving module tilts when the PTZ camera is hidden behind the large screen, and further improving the stability of the system. The positioning block can realize the quick and stable connection of the X-axis mounting plate, improving the installation efficiency. The mounting frame improves the connection stability between the electrical component mounting plate and the mounting frame. The first moving frame and the second moving frame are composed of an auxiliary plate, a connecting plate and a reinforcing plate, which improves the connection stability between the mobile display screen and the PTZ camera and the second Y-axis moving module and the first Y-axis moving module, avoids tilting, and further improves the stability of the system.

The first Y-axis moving module 6 is connected to the auxiliary slide 23. The output ends of the first Y-axis moving module 6 and the second Y-axis moving module 7 are respectively connected to a first moving frame 8 and a second moving frame 9. A fixed box 10 is connected to the first moving frame 8. A pan-tilt camera 11 is connected to the fixed box 10. A mobile display screen 12 is connected to the second moving frame 9.

[0027] Mounting bracket 1 is connected to electrical component mounting plate 13, and mounting frame 25 is also connected to mounting bracket 1. Electrical component mounting plate 13 is connected to mounting frame 25. Electrical component mounting plate 13 is connected to electrical control unit, which includes PLC main board 14. PLC main board 14 is connected to electrical component mounting plate 13. Electrical component mounting plate 13 is also connected to motor drivers 15. Three sets of motor drivers 15 control the opening and closing of X-axis movement module 5, first Y-axis movement module 6, and second Y-axis movement module 7, respectively. The electrical component mounting plate 13 is connected to a switching power supply 16 and a mainboard switching power supply 17. The mainboard switching power supply 17 is electrically connected to the PLC mainboard 14 and supplies power to the PLC mainboard 14. The switching power supply 16 supplies power to the motor driver 15 and system equipment such as the X-axis moving module 5, the first Y-axis moving module 6, the second Y-axis moving module 7, the PTZ camera 11, the intelligent remote control switch 19, the fixed display screen 3, and the mobile display screen 12. The electrical component mounting plate 13 is connected to a terminal block 18 and an intelligent remote control switch 19.

[0028] The first movable frame 8 includes a connecting plate 26 and an auxiliary plate 27. The auxiliary plate 27 is connected to the output end of the first Y-axis movable module 6. The auxiliary plate 27 is connected to a reinforcing plate 28, which is provided in two sets. The connecting plate 26 is connected to the reinforcing plate 28, and the fixed box 10 is connected to the connecting plate 26. The structure of the second movable frame 9 is the same as that of the first movable frame 8. The connection method between the movable display screen 12 and the second movable frame 9 is the same as that between the fixed box 10 and the first movable frame 8.

[0029] The X-axis moving module 5, the first Y-axis moving module 6, and the second Y-axis moving module 7 can be driven by servo motors or linear motors, or other power sources, as long as they can achieve linear motion.

[0030] The specific implementation process is as follows:

[0031] When using the device diagram Figure 1 The installation is performed as shown. For clarity, this application does not show all the stainless steel protective plates 29. In actual installation, the mounting bracket 1 has stainless steel protective plates 29 connected to all five sides except the side connected to the box fixing plate 2. This is hereby stated. Figure 1 As shown, at this time, the mobile display screen 12 is located inside the mounting bracket 1, and the pan-tilt camera 11 is located outside the mounting bracket 1.

[0032] When the video conferencing function is enabled, video capture can be achieved through the PTZ camera 11;

[0033] When the video conferencing function is turned off, the intelligent remote control switch 19 issues a command, and the first Y-axis moving module 6 drives the first moving frame 8 to move into the mounting frame 1, taking the fixed box 10 and the PTZ camera 11 into the mounting frame 1. After the first moving frame 8 is taken into the mounting frame 1, it is located between the auxiliary rail 21 and the remote sliding plate 20. The auxiliary rail 21 and the moving sliding plate 20 jointly support the first Y-axis moving module 6 and the first moving frame 8, so that the first Y-axis moving module 6 will not tilt. Then the X-axis moving module 5 is activated, driving the first Y-axis moving module 6 and the second Y-axis moving module 7 to move to the left at the same time, so that the moving display screen 12 moves to the hole. At this time, the PTZ camera 11 is located to the left of the moving display screen 12 and is blocked by the fixed display screen 3. Then the second Y-axis moving module 7 is activated, driving the second moving frame 9 and the moving display screen 12 to move in the direction close to the hole until the moving display screen 12 is inserted into the hole, so that the moving display screen 12 and the fixed display screen 3 are fully spliced, thereby realizing the LED full-screen display function.

[0034] When the video conferencing function is restarted, the intelligent remote control switch 19 issues a command, and the second Y-axis moving module 7 starts, driving the second moving frame 9 and the moving display screen 12 to move into the mounting frame 1, and then the second moving frame 9 and the moving display screen 12 are put into the mounting frame 1. Then the X-axis moving module 5 starts, driving the first Y-axis moving module 6 and the second Y-axis moving module 7 to move to the right at the same time, so that the fixed box 10 and the pan-tilt camera 11 move to the reserved hole in the middle of the fixed display screen 3. At this time, the moving display screen 12 is located to the right of the fixed box 10 and is still located in the mounting frame 1. Then the first Y-axis moving module 6 drives the first moving frame 8 to move along the first Y-axis moving module 6 towards the fixed display screen 3, so that the fixed box 10 and the pan-tilt camera 11 pass through the hole and reach the outside of the mounting frame 1, and can realize video acquisition again through the pan-tilt camera 11.
