Example Embodiment

[0027] The present invention will be described in detail below in conjunction with the drawings:

[0028] The LED display status detection method includes the following steps:

[0029] 1] Form a detection loop

[0030] 1.1] Connect the light boards of each sub-unit of the LED display in groups, and set detection sensors in each sub-unit; group connection specifically refers to the selection of the selected LED point light source on each light board with the adjacent light board LED point light source connection, this connection can choose to connect any horizontal row of the light board and the LED point light source on its adjacent light board in series, or choose vertical series connection, or randomly select point connection. At the same time, the LED point light source The connection between the two can be made by cable or other ways. The core purpose of this step is to set the necessary conditions for the circuit to be tested in step 1.2, and the conditions can be met;

Abstract

The invention provides an LED (light-emitting diode) display screen status detection device and a detection method. The detection method is mainly used for solving the problems that the existing detection method is low in detection precision and incomprehensive in detection, and is incapable of carrying winding detection and single-point detection. The LED display screen status detection device and the detection method, which are provided by the invention, can efficiently and rapidly detect the operating statuses of an LED display screen, namely the temperature, the wetness, the smoke, the voltage of a switch power supply, the on-off statuses of a fan and a case door switch, and carry out the wiring detection and single-point detection. The LED display screen status detection device and the detection method realize the monitoring to the links of the LED display screen, and save a large amount of time for maintenance work.

Description

technical field [0001] The invention belongs to an LED display screen detection device and a detection method, in particular to an LED display screen state detection device and a detection method. Background technique [0002] The structure of the LED display is complex, the working environment is harsh, and the probability of failure is high. In order to make the LED display screen play normally, it is necessary to monitor the working status of the LED display screen. The existing detection method is to adopt various troubleshooting methods to determine the cause of the problem after the display screen has a problem. However, due to the complex structure of the LED display screen, there are many reasons why the display screen cannot work normally. A lot of time will be wasted, and if it is due to insufficient technical capabilities or troubleshooting errors, the problem will become more and more serious. Contents of the invention [0003] The invention provides a LED di...
