Problems solved by technology

[0004] At the same time, the existing LED display device does not have functions such as man-machine input interface and PC download support, and can only use the storage to pre-store the display content and select it through switches. Therefore, the display content of the existing LED display device is relatively limited. and single, limiting the wide application of the device

Abstract

The invention discloses a multifunctional shaking LED display device, comprising a main control CPU unit, a movement parameter detection unit, a power management unit and an LED display column unit; the main control CPU unit can transfer the collected information which is treated by sampling into a word stock that is suitable for LED column display, and the word stock is stored in a memory in themain control CPU unit for calling; the movement parameter detection unit can detect the movement parameter when the whole LED display device shakes, and transmit the physical parameters to the main control CPU unit for treatment; the power management unit can produce the appropriate voltage so as to provide the power supply for the LED display device; the LED display column unit can display the word stock of the LED column display which is transferred by the main control CPU unit and stored in the memory in the main control CPU unit; wherein, the movement parameter detection unit is connectedwith the main control CPU unit by a digital interface, the LED display column unit is connected with the main control CPU unit by control bus and data bus, and the power management unit is connected with the main control CPU unit, the movement parameter detection unit and the LED display column unit.

Description

technical field [0001] The invention relates to an LED display device, in particular to a multi-functional shaking LED display device based on a motion sensor-based intelligent LED array to dynamically display pictures and texts. Background technique [0002] At present, the technologies and patents of dynamic display using LED columns have been reported at home and abroad. The main idea of ​​these existing technologies and devices is to pass a column of LEDs in the air at a certain speed and according to a certain track, and change the column at different times. The display content of LEDs at different track points, due to the residual effect of human vision, gives a complete picture and text display effect as a whole. [0003] However, the existing LED display devices cannot detect the parameters of the LED columns when they are shaken. Only by simply using a microprocessor to adjust the display frequency of the LED columns, it is impossible to accurately determine the max...
