Multi-sensor data transmission based on CPLD

A method for realizing multi-sensor data transmission in airborne environment is presented, and ARINC429 bus can be accomplished based on the flexible configuration of CPLD. A new encapsulation method of Link16 data link protocol and ARINC429 protocol in physical layer is also introduced. Test results show that the system can achieve credible data transmission within the distance 10 m at the rate of 100 kb/s.
