System and method for controlling LED guardrail tubes

Abstract

The invention relates to LED guardrail tubes, in particular to a system and a method for controlling LED guardrail tubes. The system is characterized by comprising the multiple LED guardrail tubes and an SD (secure digital) card controller for controlling the LED guardrail tubes, a single chip microcomputer, a serial memory, a rectification and filter voltage stabilizer and an LED lamp panel are arranged in each LED guardrail tube, the serial memory, the rectification and filter voltage stabilizer and the LED lamp panel of each LED guardrail tube are respectively connected onto the single chip microcomputer of the LED guardrail tube, each rectification and filter voltage stabilizer is connected with the corresponding LED lamp panel, one of the single chip microcomputers is used as a first single chip microcomputer to be connected with the SD card controller, and the other single chip microcomputers are sequentially serially connected with one another and then are connected onto the first single chip microcomputer.

Description

[technical field] [0001] The invention relates to an LED guardrail tube, in particular to an LED guardrail tube control system and a control method. [Background technique] [0002] Among the existing LED digital lamps, one is a purely internal control form, the lamp has a built-in single-chip microcomputer, and a control signal with a fixed changing effect is set in the single-chip microcomputer; a purely external control form, only when an external transmission signal is connected can there be a changing effect . [0003] The beneficial effect of the invention is to realize a control scheme in which the external control mode and the internal control mode coexist, and the internal control mode can be modified. When the external control mode determines the change effect, the data of the change effect can be downloaded to each lamp and stored as the internal control mode playback effect. When there is no input from the external control system, the lamp will switch to the inte...

AI Technical Summary

Problems solved by technology

[0005] 1. The change effect of LED lamps in pure internal control mode is simple, and the internal control playback mode cannot be modified

[0006] 2. The pure external control mode LED lamps can only change when there is an external control signal input. It is easy to have poor contact of the external controller signal connector, water ingress into the lamp body or damage to one of the components in the lamp, which also causes signal transmission problems. , affecting the overall playback effect

[0007] 3. When the playback effect initially shows problems, it is necessary to detect the LED lamps to find out the damage point, resulting in inconvenient maintenance and expensive maintenance costs
