Abstract


Existing LED display control system to one-way to open the way for data transmission failure on any one of the transmission path , the LED display are not displayed correctly . To solve this problem , this paper proposes a two - way loop redundancy scheme . The two - way loop redundancy scheme using Gigabit Ethernet technology to build a two-way transmission loop in the data path , each receiving card has two data stream input . The increase in this way alternate data path , you can improve the reliability of data transmission . Theoretical calculations show that the program than the one-way data transmission of the open circuit program to improve the reliability of approximately 1.7 times . The test results also show that the LED display control system uses a two-way loop redundancy scheme , data transmission fault tolerance capabilities enhance the reliability increase .
