Multi-stage series LED control method, device and equipment and storage medium

Abstract

The invention discloses a multi-stage series LED control method, device and equipment and a storage medium. The controller is additionally provided with the data end for receiving the verification data, so that whether the communication interruption is caused by the fault of the LED lamp is judged, and after the interruption, the controller simultaneously sends the data in different sequences from the first data end and the second data end, so that other LED lamps can normally receive the data, and the problem that the communication of other LED lamps is influenced due to the fault of one LED lamp is avoided; and once the controller records that the LED lamp fails, subsequent communication adopts a mode of simultaneously sending data in different sequences from the first data end and the second data end, so that the overall time of single-time communication is not increased. Therefore, the multi-stage series LED control method can reduce the system complexity and wiring cost of the multi-stage series LED, is high in anti-interference capability, effectively avoids data phase deviation, and is high in reliability.

Description

technical field [0001] The present invention relates to the technical field of LED lamp control, in particular to a method, device, equipment and storage medium for multi-stage serial LED control. Background technique [0002] The application of serial LED lamps usually includes a controller and multiple LED lamps in series. The controller has a data output terminal, and the LED lamp beads have a data input terminal and a data output terminal; at the same time, the LED lamp has a built-in communication chip and multiple LED lamps. Beads, the communication chip adjusts the luminous intensity of the LED lamp beads according to the received communication data. The working principle of the series LED light application scheme is: the data output end of the controller is connected to the data input end of the first LED light, and the data output end of the first LED light is connected to the data input end of the second LED light. analogy. When working, the data output terminal ...

Problems solved by technology

[0004] However, in actual use, because each LED lamp has two input terminals, the number of connections between modules increases, which increases the complexity of the entire system and wiring costs; in addition, too many signal lines are likely to cause mutual interference, resulting in Data communication error, the controller needs to ensure that the main data output terminal and the backup data output terminal send data at the same time, if there is a deviation in the data phase at both ends, it will also cause communication errors
