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

[0024] Such as figure 1 As shown, this embodiment provides an LED online detection control system, the LED online detection control system includes a display unit, a control unit, a detection unit and a judgment unit, wherein the LED online detection control system is used for online detection and Control each external display terminal. The display terminal includes various display devices, such as LED display screens, LED lighting, etc., and each display device can be used to display various graphics, text, letters, and animation videos. For example, it includes LED displays such as advertising screens, information screens, and animation video screens, and LED lighting such as underwater lights, guardrail tubes, and wall washers.

[0025] The control unit is connected to each component of the display terminal through a line, for example, is electrically connected to each component of the display terminal through a power line, and is signally connected to each control chip of ...

Embodiment 2

[0037] Such as figure 2 As shown, on the basis of the above examples, in the LED online detection control system provided by this embodiment, the detection unit is also connected to the control unit, the display unit, and the first judgment module, and the The detection unit is also used to detect the circuit parameters and signal input of the control unit, and generate detection data, and the first judging module judges whether the control unit is faulty, and if so, generates control unit fault data, and directly Outputting the control unit fault data to the display unit.

[0038] For example, the control unit fault data can be output to the display unit, and an alarm module can be set in the display unit, and when receiving the control unit fault data, an alarm signal is sent, such as, in the display unit By jumping out of the alarm window, in this way, it can be quickly known that the control unit is faulty, thereby avoiding wasting unnecessary resources.

Embodiment 3

[0041] Such as image 3 As shown, on the basis of the above examples, in the LED online detection control system provided by this embodiment, the control unit is also provided with a signal correction module, and the signal correction module is respectively connected with the second judgment module and the connected to the control unit.

[0042] When the second judging module judges that a signal failure occurs in the display terminal, the signal correction module is started, and the signal correction module is configured to correct the control signal according to the second failure data.

[0043] For example, the control signal of each LED before correction is input into the signal correction unit, and the second judging module judges that the relevant components in the LED display terminal are signal faults according to the detection data, and then passes the second fault Data, the specific reason for the occurrence of the signal failure can be known, such as data loss, dat...

The LED on-line detection control system has the advantages of precise detection data, accurate judging results, good detection effect and high control intelligent level.

Description

technical field [0001] The invention relates to lighting device detection technology, in particular to an LED online detection control system. Background technique [0002] With the development of LED display technology, LED display applications and LED lighting applications have become more and more widely used in various lighting applications due to their low energy consumption, strong color reproduction, long life, huge size, and unique shapes. In these applications, fault detection technology is increasingly showing its importance. Especially for LED display applications in major occasions, due to the importance of activities, the requirements for judgment and maintenance of LED display failures are also higher. [0003] In the current LED display application, although the majority of users have realized the significance of LED display fault detection technology, major manufacturers at home and abroad have also carried out research and development of fault detection tec...
