Problems solved by technology

[0004] However, the traditional HUB board is designed according to the type of receiving card, which means that a HUB board can only use a corresponding receiving card. When there are different receiving card requirements in the LED display market, different receiving cards cannot be used. The same kind of HUB board is likely to cause a backlog of goods and waste of resources, thereby increasing the cost of the enterprise. Therefore, it is of great significance to design a general-purpose HUB board

Embodiment 1

[0036] Please refer to figure 2 , the embodiment of the present invention provides a general-purpose HUB board for LED display screens, including a HUB board body 10, and the HUB board body 10 is provided with:

[0037] Input interface 11, output interface 12;

[0038] The receiving card C installation position 13 is electrically connected between the input interface 11 and the output interface 12 to form a first loop;

[0039] A1 group resistor installation position 14, electrically connected between the input interface 11 and the receiving card C installation position 13;

[0040] A2 group resistor installation position 15, electrically connected between the output interface 12 and the receiving card C installation position 13;

[0041] The receiving card D installation position 16 is electrically connected between the input interface 11 and the output interface 12 to form a second loop;

[0042] The B1 group resistance installation position 17 is electrically connected ...

Embodiment 2

[0053] Please refer to image 3 , the embodiment of the present invention provides a method for selecting cards based on the LED display universal HUB board described in Embodiment 1. The method includes:

[0054]S100. When the receiving card C needs to be used, install the receiving card C on the installation position of the receiving card C, and respectively correspond to the A1 group resistor installation position and the A2 group resistor installation position by SMT patching A1 group resistors and A2 group resistors are installed, so that the first loop is turned on;

[0055] S200. When the receiving card D needs to be used, install the receiving card D on the installation position of the receiving card D, and respectively correspond to the B1 group resistance installation position and the B2 group resistance installation position by SMT patching A group of resistors B1 and a group of B2 are installed to make the second loop conduction.

Abstract

The invention discloses a universal HUB board for an LED display screen and a card selection method. The HUB board comprises an HUB board body, and the HUB board body is provided with an input interface, an output interface, a receiving card C mounting position, an A1 group of resistor mounting positions, an A2 group of resistor mounting positions, a receiving card D mounting position, a B1 groupof resistor mounting positions, a B2 group of resistor mounting positions, an indicator lamp and a lamp panel. According to the universal HUB board for the LED display screen and the card selection method, on the premise that the display effect is guaranteed, two different types of receiving cards can be selectively installed on the same HUB board, inventory overstocking and resource waste of theHUB board are reduced, and therefore enterprise cost is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of HUB boards for LED display screens, in particular to a universal HUB board for LED display screens and a card selection method. Background technique [0002] With the development of LED display technology, its application fields are becoming more and more extensive. At the same time, the development trend of the LED display industry is simpler structure, more convenient installation and maintenance. [0003] At present, the structure of the HUB board in the LED display market is as follows: figure 1 As shown, its working method is that the external signal of a cabinet enters through the input interface, and then it is sent to the receiving card, and the receiving card is respectively sent to each lamp board through processing, and in order to reflect the working status of the receiving card, it is on the HUB board Add an indicator light, and finally, in order to enable the external ...
