Description

Technical Field

[0001] The utility model relates to the technical field of monitoring equipment, and in particular to a multi-screen monitoring equipment based on information technology. Background Art

[0002] In today's surveillance technology landscape, with the continuous advancement of informatization and intelligence, multi-screen surveillance equipment has become critical in various scenarios, including security monitoring, traffic management, and production monitoring. Traditional surveillance display systems often utilize multiple independent display screens spliced ​​together. This approach not only creates a visual fragmentation due to wide bezels, affecting the integrity and continuity of the surveillance image, but also presents numerous challenges in heat dissipation, dust and insect protection, and ongoing maintenance.

[0003] First, due to the wide borders between the display screens in traditional multi-screen splicing systems, when spliced ​​into a large screen, the borders occupy a large amount of visible area, affecting the integrity and clarity of the monitoring image. This visual discontinuity can significantly reduce the monitoring effect, especially when panoramic monitoring or detailed observation is required. Secondly, traditional monitoring equipment often lacks a unified planning for heat dissipation design. Each display screen and internal circuit board dissipates heat independently, which is not only inefficient but also prone to forming local hot spots, affecting the stability and service life of the equipment. Furthermore, traditional multi-screen monitoring equipment also has many inconveniences in terms of subsequent maintenance and upgrades. Because the display screens and circuit boards are often integrated into a single design, if a failure occurs or an upgrade is required, the entire system often needs to be disassembled, which is not only time-consuming and labor-intensive, but also prone to causing secondary damage to the equipment. In addition, maintenance of key components such as circuit boards usually requires professional personnel to deeply penetrate the equipment, which is not only difficult to operate but also poses safety risks. Utility Model Content

[0004] In view of the deficiencies of the existing technology, the present invention provides a multi-screen monitoring device based on information technology, which has the advantages of separate design of display screen and circuit board and improved heat dissipation effect, and solves the problems raised in the background technology.

[0005] The utility model provides the following technical solutions: a multi-screen monitoring device based on information technology, including an assembly frame and a circuit board, the front end of the assembly frame is equipped with evenly distributed and closely attached narrow-edge LCD screens, the rear end of the narrow-edge LCD screen is fixedly connected to a fixing plate near the left and right sides, a first heat sink is fixedly connected between the fixing plates, the first heat sink is in contact with the narrow-edge LCD screen, a second heat sink is inserted between the gaps of the rear end fins of the first heat sink, the second heat sink and the fins on the first heat sink are provided with slide grooves near the upper and lower sides, the interior of the slide grooves passes through and slidably installs a limit plate, fixing components are provided at the four corners of the circuit board, the circuit board is fixedly installed in the middle of the rear end of the second heat sink through the fixing component, and a strip fan is fixedly installed near the lower side inside the assembly frame.

[0006] Furthermore, the rear ends of the fixing plates are symmetrically provided with connectors, and the rear ends of the connectors are fixedly connected to the inner walls of the assembly frame. This fixing method ensures a seamless assembly effect of the front end of the narrow-edge LCD screen.

[0007] Furthermore, the circuit board integrates a power supply and an image processing unit and both are electrically connected to the narrow-edge LCD screen. That is, the connection between the narrow-edge LCD screen and the circuit board is still traditional, but certain changes have been made in the installation method, which improves the compatibility and feasibility of this solution.

[0008] Furthermore, there is a certain gap between the fins of the first heat sink and the second heat sink, and the limiting plate is provided with evenly distributed ventilation holes, which ensures the heat dissipation effect of the strip fan after it is turned on and avoids mutual obstruction between the structures to reduce the heat dissipation area.

[0009] Furthermore, a rear heat dissipation mesh plate is provided at the rear end of the assembly frame near the strip fan, and an upper heat dissipation mesh plate is provided at the upper end of the assembly frame for heat exchange between the interior of the assembly frame and the outside, thereby ensuring the rationality of the structural design.

[0010] Furthermore, a cover plate is provided at the rear end of the assembling frame corresponding to the narrow-edge LCD screen, a hinge is fixedly installed at the middle of the lower end of the cover plate, the cover plate is rotatably connected to the assembling frame through the hinge, and a rotating lock is fixedly installed at the middle of the upper side of the rear end of the assembling frame near the cover plate, the rotating lock is adapted to the cover plate, and a breathable net is provided in the middle of the cover plate, that is, the operation of opening the interior of the assembling frame is simple and quick, and the heat dissipation effect of the device is further improved by the design of the breathable net.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The rear end of the narrow-edge LCD screen of this monitoring device is exposed. The back plate of the assembly frame serves as an integral back cover, which can prevent dust and insects while reducing costs and improving the heat dissipation effect. At the same time, the first heat sink is used to effectively transfer the heat generated by the narrow-edge LCD screen to the fins, and the heat of the circuit board is also transferred to the fins thereon through the second heat sink. This design not only increases the heat dissipation area, but also accelerates the flow of hot air around the fins through the heat convection formed by the strip fan, and smoothly discharges the heat to the outside of the device through structures such as the upper heat dissipation mesh plate. In addition, this device can reduce heat concentration and reduce the mutual influence between structures by separating the circuit board from the narrow-edge LCD screen. At the same time, it improves the heat dissipation effect and ensures the normal use and service life of the narrow-edge LCD screen.

[0013] 2. The structural design of this monitoring equipment fully considers the convenience of overhaul and maintenance. By installing the circuit board and the narrow-edge LCD screen separately, the two can be maintained or replaced separately when they need to be maintained. In particular, when upgrading or maintaining the circuit board, the corresponding circuit board can be found after opening the cover. In addition, the design of the limit plate and the slide groove provides great convenience for maintenance personnel, allowing them to directly pull the second heat sink to move the circuit board to the outside, and maintenance work can be carried out without disassembling the entire equipment. This optimized structural design not only saves maintenance time, but also reduces the difficulty of operation and improves the maintainability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

When in use, unlike traditional display screens, the rear end of the narrow-edge LCD screen 2 is exposed. The back plate of the assembled frame 1 is used as an integral back cover to prevent dust and insects while reducing costs and improving the heat dissipation effect. At the same time, unified heat dissipation treatment can be carried out. Specifically, the heat generated on the narrow-edge LCD screen 2 can be transferred to the fins through the heat conduction effect of the first heat sink 5, and the heat generated by the circuit board 9 can be transferred to the fins thereon through the second heat sink 6, thereby realizing effective heat transfer and dispersion, thereby achieving the purpose of cooling through its large heat capacity and surface area, and then forming heat convection by turning on the strip fan 11, driving the hot air around the fins to flow upward and be discharged outward through structures such as the upper heat dissipation mesh plate 14, thereby achieving the heat dissipation effect. Furthermore, the device can reduce heat concentration and reduce the mutual influence between structures by separating the circuit board 9 from the narrow-edge LCD screen 2.

The power supply and image processing unit are integrated on the circuit board 9 and are electrically connected to the narrow-edge LCD screen 2. The monitoring device can first transmit the pictures taken by the monitoring camera to the narrow-edge LCD screen 2 in real time through network transmission technology, so that the staff can observe the shooting pictures through the narrow-edge LCD screen 2. At the same time, through video fusion and splicing as well as software control technology, the ultra-narrow frame design of the narrow-edge LCD screen 2 can visually achieve a seamless splicing effect, so that the spliced ​​video can form a panoramic screen, so that the supervisor can see the monitoring pictures from multiple angles at the same time on a large screen composed of multiple narrow-edge LCD screens 2, which is convenient for global monitoring and rapid backtracking. At the same time, the size of the assembly frame 1 can be customized or the camera position can be reserved according to actual conditions, so that it can accommodate enough narrow-edge LCD screens 2, which is convenient for later use and more flexible.

[0023] See also Figure 3-Figure 5 There is a certain gap between the fins of the first heat sink 5 and the second heat sink 6. The limiting plate 8 is provided with evenly distributed ventilation holes 12, which ensures the heat dissipation effect of the strip fan 11 and avoids the airflow from being blocked. The rear end of the assembly frame 1 is provided with a rear heat dissipation mesh plate 13 near the strip fan 11, and the upper end of the assembly frame 1 is provided with an upper heat dissipation mesh plate 14, which can prevent dust and insects while allowing the heat inside the assembly frame 1 to be discharged to the outside.

The cover plate 16 is rotatably connected to the assembly frame 1 through the hinge 15, and the rear end of the assembly frame 1 is fixedly installed with a rotating lock 17 near the middle of the upper side of the cover plate 16.

The corresponding circuit board 9 can be found after flipping the cover plate 16 downward. The limit plate 8 not only connects the first heat sink 5 and the second heat sink 6, but also, due to the design of the slide groove 7, the maintenance personnel can directly pull the second heat sink 6 to drive the circuit board 9 to move to the outside, which provides greater flexibility for the maintenance and upgrading work of the maintenance personnel and greatly improves the work efficiency.

[0025] Working principle: This monitoring device can first transmit the images captured by the monitoring camera to the narrow-edge LCD screen 2 in real time through network transmission technology, so that the staff can observe the captured images through the narrow-edge LCD screen 2. At the same time, through video fusion and splicing as well as software control technology, the ultra-narrow frame design of the narrow-edge LCD screen 2 can achieve a seamless splicing effect visually, so that the spliced ​​video can form a panoramic view screen, so that the supervisor can see the monitoring images from multiple angles at the same time on a large screen composed of multiple narrow-edge LCD screens 2. When in use, unlike traditional display screens, the rear end of this narrow-edge LCD screen 2 is exposed, and the back plate of the assembly frame 1 is used as an integral back cover. The heat generated on the narrow-edge LCD screen 2 can be transferred to the fins through the heat conduction effect of the first heat sink 5, and can be transferred to the fins through the second heat sink 6. The heat generated by the circuit board 9 is transferred to the fins thereon. By turning on the strip fan 11, the hot air around the fins can be driven to flow upward and discharged outward through structures such as the upper heat dissipation mesh plate 14. Furthermore, the device can reduce heat concentration by separating the circuit board 9 from the narrow-edge LCD screen 2. In addition, the separate installation design makes the narrow-edge LCD screen 2 and the circuit board 9 more convenient when they need to be maintained or replaced. Especially when upgrading or maintaining the circuit board 9, the locking member 17 can be rotated to release its restrictive effect on the cover 16, so that the corresponding circuit board 9 can be found after flipping the cover 16 downward. The limiting plate 8 not only serves to connect the first heat sink 5 and the second heat sink 6, but also, due to the design of the slide groove 7, the maintenance personnel can directly pull the second heat sink 6 to move the circuit board 9 to the outside.
