Problems solved by technology

However, subject to various factors of technical strength, the current fault judgment is mostly focused on visual observation and empirical judgment, and the detection methods also stay in off-line detection methods such as multimeters and oscilloscopes. The efficiency is low, the effect is poor, the detection methods are backward, and the accuracy is not high. Low level of intelligence

Embodiment 1

[0021] As shown in Figure 1, this embodiment provides an LED display system, the LED display system includes a display device and a detection and control device, the detection and control device is used to detect and control the display device, the display device uses Used to display graphics, text, letters, animations, etc.

[0022] The display device can be a general-purpose LED display screen, or a transparent LED display screen, or an LED display module, etc. The display device includes one or more unit boards, each unit board is provided with a PCB board, and a plurality of LED pixels arranged in a dot matrix are mounted and fixed on the PCB board, and the positive power line of the power supply is printed on the PCB board , power supply negative line, signal line, etc., as well as other electronic components and electronic circuits, such as capacitors, resistors, etc.

[0023] The detection and control device includes a detection module and a control module, wherein the...

Embodiment 2

[0036] As shown in Figure 2, on the basis of the above examples, in the LED display system, the inspection and control device also includes the display terminal, for example, the display terminal can be a display module, and the display module and The status feedback sub-modules are connected to each other, and display the status of the display device as a man-machine display interface by receiving the detection data from the status feedback sub-modules.

[0037] For example, the display module can be an LED display module, an LCD display, or other display modules. Through the display module, the state of the display device can be seen very intuitively, for example, each LED in the display device can be displayed The pixel point and the connection line between the two LED pixel points are in a fault state or display a normal state.

[0038] In addition, the display terminal is also provided with a graphic function sub-module, that is, the status of the display device is displa...

Embodiment 3

[0041] On the basis of the above examples, the detection and control device further includes a box body; wherein, the detection module, the control module and the display terminal are all fixedly arranged in the box body, and the display terminal A display interface is provided on the outside of the box, for example, an observation surface is provided on the box, which can be used to observe the display interface of the display terminal.

[0042] By arranging each module in the box body, the box body plays a role of fixing, waterproofing, and anti-collision protection for each module and the display terminal, and is convenient to move; moreover, it can be directly viewed from the outside of the box body The state of the display device is very intuitive and convenient to use.

[0043] Alternatively, the inspection and control device may also be configured to include two boxes; wherein, the detection module and the control module are set in one box, the display terminal is set i...
