Technical Field
[0001] This utility model relates to the technical field of LED display installation, and more specifically, to a control box and display module for an outdoor LED display that requires no debugging. Background Technology
[0002] LED splicing displays are mainly divided into indoor LED displays and outdoor LED displays according to their application scenarios. Outdoor LED displays are ubiquitous in landmark buildings, outdoor media, advertising signs, public transportation and other scenarios.
[0003] Currently, outdoor LED displays are still relatively complex to install and use. Firstly, in terms of power supply and signal control, power supply and signal are usually separated into two separate circuits, such as... Figure 1 During LED screen installation, each LED cabinet module requires a power cable and a signal cable. The power cable connects to the electrical box to provide 100-220V power to the screen, while the signal cable, typically a network cable, connects to the output port of the transmitting card to provide image control signals. Considering load capacity, multiple power cables and main network cables may be connected, resulting in numerous connections. Therefore, installation requires professional guidance or installation by qualified personnel. Secondly, after the LED display screen is installed and connected, professionals familiar with the control system software are needed to perform software connection operations to achieve single-module image splicing and large-screen playback. Finally, outdoor LED displays often present installation and maintenance difficulties. Their smallest unit is a small-sized module, which is then assembled into a cabinet. The cabinet contains components such as power supplies, receiver cards, adapter boards, and ribbon cables. Installation and maintenance typically require troubleshooting numerous components, including modules and power supplies, necessitating professional replacement or guidance.
[0004] In addition, the installation structure is not standardized and requires professional guidance for installation and fixation. Therefore, outdoor fixed display screens currently face problems such as difficult installation and construction, the need for professional assistance, and long installation and delivery times. Utility Model Content
[0005] The purpose of this utility model is to provide a control box and display module for an outdoor LED display screen that does not require debugging. Installation only requires fixing the structure to the wall, fixing the display units one by one to the structural frame, and connecting each display unit with one wire to form multiple rows of display modules in series. The wires of each row or column are connected to the waterproof control box in a specified manner, and the installation and use are completed. This invention aims to solve the problems in the prior art.
[0006] This invention is implemented as follows: a control box for an outdoor LED display screen that requires no debugging includes a protective housing. One side of the protective housing has a power input aviation connector, and the other side has an electrical data encoding signal output aviation connector. A protection module is housed inside the protective housing. The power input aviation connector and the electrical data encoding signal output aviation connector are both electrically connected to the protection module. A control box transformer power supply is located on one side of the protection module, and a cloud playback card is located on one side of the control box transformer power supply. The output end of the cloud playback card is connected to the electrical data encoding signal output aviation connector. The control box transformer power supply is electrically connected to the cloud playback card, the power input aviation connector, and the protection module.
[0007] Furthermore, the input end of the cloud playback card is sequentially provided with a USB connector, a wireless module, and a light probe. The USB connector, wireless module, and light probe are used to output external signals to the cloud playback card. The cloud playback card sends the electrical data encoding signal to the electrical data encoding signal output aviation plug to complete the transmission to the display unit.
[0008] Furthermore, the number of the power input aviation plug and the electrical data encoding signal output aviation plug is 1-10.
[0009] Furthermore, the output end of the cloud playback card is connected to a built-in transmitting card, which is electrically connected to the aviation plug for outputting electrical data encoding signals and the power supply of the control box transformer.
[0010] Furthermore, the protection module is one or two of the following connected together: a leakage current protector, a PLC, and a timer.
[0011] Furthermore, the power input aviation plug is connected to an external power supply box, which transmits electrical energy to the control box to power data signal transmission.
[0012] Compared with the prior art, the control box and display module of the outdoor LED display screen that do not require debugging provided by this utility model have the following advantages:
[0013] 1. Installation is simpler. The system card and power supply are fixed behind the large module as a whole display unit. The display unit has a magnetic buckle on the back. Installation only requires fixing the structure to the wall and fixing the display units one by one to the structural frame. Connecting each display unit with one wire can form multiple rows of display modules in series. Connect the wires of each row or column to the waterproof control box in the prescribed way to complete the installation and use.
[0014] 2. Outdoor LED displays are cleaner and more aesthetically pleasing. The back of the screen now features a single cable connecting rows or columns, which is much more efficient than conventional solutions that require network cables and power cables. Conventional solutions also have irregular power and network cables that cross multiple rows or columns and are bent or bent. Furthermore, installation does not require professional LED display technicians to install or guide the installation, and no debugging is needed. The signal cables are connected after the modules are installed and ready to use.
[0015] 3. The LED display screen is easy to maintain in the later stages of use. The only accessories are modules, cables, and waterproof playback boxes. If any part fails, just replace the spare part. Problem diagnosis and maintenance are quick. Moreover, it realizes a series of functions such as wireless control, USB flash drive insertion, timed screen on / off, remote screen on / off, automatic adjustment of screen brightness according to ambient brightness, and changing programs anytime and anywhere through the cloud platform. No other accessories are required.
[0016] The display module of the outdoor LED display screen that requires no debugging includes a display unit and a control box. The display unit and the control box are electrically connected, and the control box is the control box of the outdoor LED display screen that requires no debugging as described above.
[0017] Specifically, the display unit includes a power supply box, a receiving card is provided on one side of the power supply box, a display transformer power supply is provided below the receiving card, and a signal receiving port is provided on one side of the lower part of the power supply box.
[0018] Specifically, the display transformer power supply is electrically connected to the signal receiving port and the receiving card respectively. The signal receiving port receives the electrical data encoding signal output from the aviation plug, and after being processed by the display transformer power supply, it is sent to the receiving card to complete the signal output display.
[0019] Specifically, the display unit is fixed to the frame using a magnetic attraction and anti-detachment buckle. Before each display unit is installed, two display units are connected horizontally to complete the multi-line signal output module series connection. Each of the electrical data encoding signal output aviation plugs outputs signals to each corresponding signal output module, and the screen connection action is triggered by the built-in sending card program.

[0029] Example 1
[0030] Reference Figure 2As shown, the control box for the outdoor LED display screen that requires no debugging includes a protective housing 17, which provides waterproof and dustproof protection. One side of the protective housing 17 has a power input aviation plug 4, and the other side has an electrical data encoding signal output aviation plug 5. Inside the protective housing 17 is a protection module 6, which is connected to one or more of a leakage current protector, a PLC, and a timer. The power input aviation plug 4 and the electrical data encoding signal output aviation plug 5 are both electrically connected to the protection module 6. A control box transformer power supply 7 is located on one side of the protection module 6, and a cloud playback card 9 is located on the other side. The output of the cloud playback card 9 is connected to the electrical data encoding signal output aviation plug 5. The power supply of the control box transformer 7 is electrically connected to the cloud playback card 9, the power input aviation plug 4, and the protection module 6.
[0031] In this embodiment, the input end of the cloud playback card 9 is sequentially provided with a USB connector 10, a wireless module 11, and a light probe 12. The USB connector 10, the wireless module 11, and the light probe 12 are used to output external signals to the cloud playback card 9. The cloud playback card 9 sends the electrical data encoding signal to the electrical data encoding signal output aviation plug 5 to complete the transmission to the display unit 3.
[0032] Specifically, electrical data encoding signals include HDMI, DVI, SDI, and video signals played internally by cloud playback boxes, etc., through...
[0033] In this embodiment, the number of power input aviation plug 4 and electrical data encoding signal output aviation plug 5 is 1-10.
[0034] Taking the eight power input aviation plugs 4 and the electrical data encoding signal output aviation plugs 5 as an example, the waterproof power supply box's power input port 1 is connected to the corresponding two-in-one signal output port 1, input port 2 is connected to output port 2, and so on, with other input and output ports numbered one-to-one. When the LED display screen has only one row, input port 1 is used for power supply connection, also powering the cloud playback box and sending card to achieve control purposes. In addition, the built-in sending card 8 or cloud playback card 9 connects to interfaces or accessories such as USB, Wi-Fi antenna, and light probe 12, enabling functions such as USB flash drive playback, Wi-Fi wireless internet access, Wi-Fi wireless control, and automatic adjustment of screen brightness based on ambient light sensing. The high-voltage electricity inside the waterproof playback box passes through... The system can be equipped with various devices, including but not limited to leakage current protectors, PLCs, and timers, to achieve overload protection for each power supply current, customized switch panels, and remote switch panel functions. This allows customers to manage and use outdoor LED displays more intelligently and simply. The built-in sending card 8 and cloud playback card 9 can be control system cards from brands such as Nova, Carlette, and Mosier, or they can be self-developed control cards to achieve these functions. Customers only need to connect the signal output port 1 to the first row or first column of the screen, and the output port 2 to the second row or second column of the screen. By customizing the sending card program, the screen connection is triggered as soon as the sending card is powered on, without the need for manual software debugging.
[0035] The power input aviation plug 4 connects to the external power supply box 1. The power supply box 1 transmits electrical energy to the control box to power the data signal transmission. This technical solution is simpler to install. The system card and power supply are fixed behind the large module as an integrated display unit. The display unit has a magnetic buckle on the back. Installation only requires fixing the structure to the wall and fixing the display units one by one to the structural frame. Each display unit is connected with one wire to form multiple rows of display modules in series. The wires of each row or column are connected to the waterproof control box in the prescribed manner to complete the installation and use.
[0036] This technical solution makes outdoor LED displays cleaner and more aesthetically pleasing. The back of the screen now features a single cable connecting rows or columns, eliminating the need for network and power cables compared to conventional solutions. Conventional solutions often involve irregular wiring, such as power and network cables crossing multiple rows or columns and being bent. Installation requires no professional LED display technicians or guidance, and no debugging is needed; the signal cable is connected after module installation and it's ready to use. Maintenance is simple, requiring only modules, cables, and a waterproof playback box. Faulty parts can be easily replaced with spares, making troubleshooting and maintenance quick and easy. Furthermore, it enables wireless control, USB flash drive playback, timed on / off switching, remote on / off switching, automatic brightness adjustment based on ambient light, and program changes via a cloud platform anytime, anywhere, without requiring any additional accessories.
[0037] Reference Figure 4-5As shown, the display module of the no-adjustment outdoor LED display includes a display unit 3 and a control box. The display unit 3 and the control box are electrically connected, and the control box is the control box of the aforementioned no-adjustment outdoor LED display.
[0038] In this embodiment, the display unit 3 includes a power supply box 13. A receiver card 14 is disposed on one side of the power supply box 13. A display transformer power supply 15 is disposed at the lower part of the receiver card 14. A signal receiving port 16 is disposed on one side of the lower part of the power supply box 13. The display transformer power supply 15 is electrically connected to the signal receiving port 16 and the receiver card 14 respectively. The signal receiving port 16 receives the electrical data encoding signal output from the electrical data encoding signal output aviation plug 5, processes it after being processed by the display transformer power supply 15, and sends it to the receiver card 14 to complete the signal output display.
[0039] In this embodiment, the display unit 3 is fixed to the frame by magnetic attraction and anti-detachment buckle. Before each display unit 3 is installed, every two display units 3 are connected horizontally to complete the multi-line signal output module series connection. Each electrical data encoding signal output aviation plug 5 outputs the signal to the corresponding signal output module, and the screen connection action is triggered by the built-in sending card program.
[0040] Example 2
[0041] Reference Figure 3 As shown, the control box for the outdoor LED display screen that does not require debugging has a built-in transmitting card 8 connected to the output end of the cloud playback card 9. The built-in transmitting card 8 is electrically connected to the aviation plug 4 for electrical data encoding signal output and the transformer power supply 7 of the control box. Of course, the waterproof playback box is not limited to integrating the built-in transmitting card 8 and the cloud playback card 9 into one board, or the switching power supply can also be integrated into the same board. It still has all the functions when the front panel card is separated, and achieves features such as smaller size and volume.
[0042] The remaining technical features of this embodiment are the same as those of Embodiment 1.
[0043] The built-in transmitting card 8 is the core signal processing and distribution hub inside the control box. Its primary function is to receive the display content signal from the cloud playback card 9 after preliminary processing, and to perform in-depth encoding, packaging, and protocol conversion. The core function of the built-in transmitting card 8 is to accurately segment and copy the complete display image signal according to the physical arrangement and resolution of the display screen. It uses algorithms to convert video or image signals into specific data formats (such as point-to-point mapping) that can be recognized by the LED display driver chip, and sends different data blocks synchronously and at high speed to the corresponding display unit 3 area through multiple electrical data encoding signal output connectors 5 connected to its back end, ensuring that the entire large screen display content is complete, seamless, and synchronized.
[0044] The receiver card 14 is the signal decoding and control center installed in the power supply box of the display unit 3. It receives specific data signal packets, which have been encoded and segmented, from the transmitting card 8 built into the control box via an aviation connector through the signal receiving port 16. The primary task of the receiver card 14 is to decode the high-speed data stream and convert the received digital signal into a driving signal that can directly control the LED beads' on / off state, color, and brightness. It has powerful data processing capabilities and can perform color correction, brightness adjustment, and scanning control to match different models of LED modules. In addition, the receiver card 14 also undertakes the fault detection and reporting functions of the display unit 3 at this level, thus forming a stable signal chain and ensuring the reliability of long-distance transmission. It is the efficient work of the receiver card 14 at the terminal that enables the commands issued by the control box to be accurately converted into brilliant visual effects.
[0045] In this embodiment, the entire operation process can be controlled by a computer, which provides signal feedback and ensures that the steps are performed sequentially. These are all standard knowledge in current automation control, and will not be elaborated on in this embodiment.
[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
