Description

Technical Field

[0001] This utility model relates to the field of information board technology, and in particular to an integrated power and data connector between information board modules. Background Technology

[0002] Information boards are primarily used to provide real-time traffic information, route navigation, safety warnings, and management instructions to help drivers drive safely and efficiently. They display real-time road conditions, weather warnings, and instructions from management departments via LED screens, enabling drivers to adjust their routes accordingly. On highways and at transportation hubs, information boards can publish ramp control plans, traffic flow guidance information, and accident warnings to optimize traffic flow and reduce safety hazards. In emergencies, information boards can quickly disseminate traffic control notices, road closures, or safety alerts to assist in the rapid evacuation of people and vehicles.

[0003] The existing information boards contain multiple LED display modules that are connected via data cables, and each LED display module requires an external data cable to connect to the controller. This data transmission and power supply method increases the complexity of wiring, thereby increasing the probability of equipment failure points due to wiring problems. In addition, most of the LED display modules are installed in the information board casing using screws, which reduces the convenience of installation and maintenance of the LED display modules. Therefore, it is necessary to design an integrated power and data connector between information board modules to solve the above problems. Utility Model Content

One of the purposes of this utility model is to provide an integrated power and data connector between information board modules.

[0005] One of the objectives of this utility model is achieved through the following technical solution: an integrated power and data connector between information board modules, comprising an installation structure: the installation structure includes a housing, a support component mounted on the inner wall of the housing, and a transparent panel mounted on the front surface of the housing; a controller body is provided on the outer side of the housing, and an output interface one is provided on one side of the controller body; an LED display module body is installed inside the housing via the support component; an input interface and an output interface two are respectively provided on the two side walls of the LED display module body; an aviation plug connector is inserted into the inner wall of the input interface; the output interface two is connected to the output interface one via the aviation plug connector; an L-shaped docking plate one and an L-shaped docking plate two are respectively fixed on one side wall of the LED display module body, the L-shaped docking plate one and the L-shaped docking plate two overlap, and both the L-shaped docking plate one and the L-shaped docking plate two have limiting holes.

[0006] According to the aforementioned integrated power and data connector between information board modules, the support assembly consists of a support frame equidistantly fixed to one side of the inner wall of the housing, a limiting rod equidistantly fixed to one side of the inner wall of the support frame, and support columns equidistantly fixed to both sides of the support frame.

[0007] According to the integrated power and data connector between information board modules, both the limiting rod and the limiting hole are hexagonal, and the limiting rod and the limiting hole are connected in a limiting insertion manner.

[0008] According to the integrated power and data connector between information board modules, the height of the inner wall of the support frame is consistent with the height of the L-shaped docking plate.

[0009] According to the aforementioned integrated power and data connector between information board modules, both the housing and the support assembly are made of aluminum profiles, and the housing has an opening on the side near the controller body.

[0027] Reference Figures 1-6An integrated power and data connector for information board modules includes an installation structure 1. The installation structure 1 includes a housing 101, a support component 102 mounted on the inner wall of the housing 101, and a transparent panel 103 mounted on the front surface of the housing 101. A controller body 2 is disposed on the outer side of the housing 101, and an output interface 3 is disposed on one side of the controller body 2. An LED display module body 4 is mounted inside the housing 101 via the support component 102. Input interfaces 5 and output interfaces 6 are respectively disposed on the two side walls of the LED display module body 4. An aviation plug connector 7 is inserted into the inner wall of the input interface 5, and the output interface 6 is connected to the aviation plug connector. 7 is connected to output interface 3. L-shaped docking plates 8 and 9 are fixedly mounted on one side wall of the LED display module body 4. The L-shaped docking plates 8 and 9 overlap. Both L-shaped docking plates 8 and 9 have limiting holes 10. The support assembly 102 consists of a support frame 1020 equidistantly fixed to one side of the inner wall of the housing 101, limiting rods 1021 equidistantly fixed to one side of the inner wall of the support frame 1020, and support columns 1022 equidistantly fixed to both sides of the support frame 1020. The limiting rods 1021 and limiting holes 10 are hexagonal. The limiting rods 1021 and limiting holes 10 are inserted into each other for a limiting fit. The support frame 1... The height of the inner wall of 020 is consistent with the height of the L-shaped docking plate 8. The controller body 2 consists of an MCU minimum system (including clock, reset, communication interface, etc., i.e., information board control card), a carrier adjustment module, a power coupling circuit, and a status indication circuit. The MCU minimum system, carrier adjustment module, power coupling circuit, and status indication circuit are interconnected. The LED display module body 4 consists of an LED bead array circuit, an LED driver chip circuit, a carrier demodulation module, a power coupling circuit, and an MCU minimum system. The MCU minimum systems are interconnected. The internal structures of the controller body 2 and the LED display module body 4 are based on existing mature technologies. Therefore, their connection methods and power modulation and distribution working principles will not be described in detail. By setting L-shaped docking plates 8 and 9 on the back of multiple LED display module bodies 4, the interconnection between multiple LED display module bodies 4 can be facilitated. With the support component 102, multiple LED display module bodies 4 can be limited and fixed to the inner wall of the housing 101, thereby facilitating the quick assembly of multiple LED display module bodies 4 onto the inner wall of the housing 101 and effectively improving installation and maintenance efficiency.

[0028] Both the housing 101 and the support assembly 102 are made of aluminum profile. The housing 101 has an opening 11 on the side near the controller body 2. A sealing ring 12 is installed on the inner wall of the opening 11. The opening 11 facilitates the connection of one end of the aviation plug connector 7 through the housing 101 to the input interface 5 of the LED display module body 4. The size of the inner wall of the sealing ring 12 is adapted to the size of the outer wall of the end of the aviation plug connector 7, which prevents external dust and rainwater from entering the housing 101 through the opening 11 and affecting the operation of multiple LED display module bodies 4, thus playing a role in sealing and protection.

[0029] An outer frame 13 is installed on the outer surface of the transparent panel 103. Mounting holes 14 are equally spaced on the upper and lower surfaces of the outer frame 13. Screws 15 are threaded onto the inner wall of the mounting holes 14. The screws 15 are threaded onto the housing 101, which facilitates the assembly of the outer frame 13 and the housing 101 to form the overall frame of the information board, making installation convenient.

[0030] A sealing ring 16 is fixed on the outer wall of the outer frame 13, which makes the outer frame 13 and the inner wall of the box 101 more tightly assembled, preventing external dust and rainwater from entering the box 101 and playing a role in sealing and protection.

[0031] Working principle: When assembling the entire information board, place the transparent panel 103 on the assembly table, then place one LED display module body 4 in a suitable position on the transparent panel 103. Connect the input end of another LED display module body 4 to the output end of the first LED display module body 4. While the output and input ends of the two LED display module bodies 4 are connected, the L-shaped docking plate 1 8 of one LED display module body 4 overlaps the L-shaped docking plate 2 9 of the other LED display module body 4. At this time, the limiting holes 10 on the L-shaped docking plate 1 8 and the L-shaped docking plate 2 9 are aligned. Multiple LED display module bodies 4 are assembled horizontally by docking, and several LED display module bodies 4 are assembled into multiple rows of display components. The multiple rows of display components form the information board display screen. The housing 101 is assembled on the transparent panel 103. The multiple limiting rods 1021 of the support component 102 are aligned with the multiple limiting holes 10, and the limiting rods 1021 are inserted into the inner wall of the limiting holes 10. At this time, the housing 101 is located on the outer wall of the outer frame 13, and several LED display module bodies 4 are located between the transparent panel 103 and the support frame 1020. Then, multiple screws 15 are screwed into the mounting holes 14 to assemble the housing 101 and the outer frame 13 together. Thus, several LED display module bodies 4 are limited and fixed inside the housing 101. Compared with the existing method of installing LED display module bodies 4 inside the housing 101 by screws 15, the connection between the LED display module bodies 4 and the housing 101 in this assembly method is more convenient, greatly improving the assembly efficiency and facilitating maintenance and disassembly.

[0032] After the information board is fully assembled, the first LED display module body 4 of each row is connected to the controller body 2 using the aviation plug connector 7. The entire workflow of the information board is as follows:

[0033] Data sent by the information board control card inside the controller body 2 is transmitted to the signal processing module at the transmitting end via a data communication interface. The signal processor at the transmitting end receives the data to be transmitted, processes it, encodes it using different encoding methods, modulates the transmitted data, and then transmits the communication signal to the power supply line of the power supply system via power line coupling. The receiving end receives the modulated signal sent by the transmitting end through the power line coupling interface circuit, demodulates it to obtain the transmitted data information, and sends it to the microprocessor at the receiving end for analysis and processing. Then, the microprocessor connects to the pins of the LED driver chip to perform corresponding display control. Similarly, the LED display module body 4 can also use a similar process to transmit data to the LED driver chip. The information board control card sends data information. The LED display module bodies 4 in each row are directly connected by input-output terminals. At this time, the controller body 2 only needs to transmit the data to the first LED display module body 4 in each row, changing the transmitted data from the original data corresponding to a single LED display module body 4 to the corresponding data of multiple LED display module bodies 4 in that row. In this way, the hardware design only needs to adjust the initial LED display module body 4 that receives the data, thus eliminating the need for multiple external data lines. This method realizes the power supply and display data input of multiple LED display module bodies 4, saving wiring time, reducing equipment failure points caused by wiring, and effectively improving maintenance efficiency.

[0034] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
