Digitized electronics systems are interconnected through a specified data bus interface to each terminal. The Integrated Modular Avionics (IMA) is an idea to realize the avionic functions by common standardized elements or modules to be integrated into one or more units or cabinets for different functional domains. Several avionics hardware or cabinets are interconnected by ARINC 629 global data buses into an integrated system for performing all functions onboard of the aircraft. However for general aircraft avionics, ARINC 629 data bus organization is too huge, expensive and complicate to implement. The goal of this thesis is to study and provide an adaptable and useful interface bus system for small aircraft. CAN (Controller Area Network) bus and TTP field bus should be a good choice to study. 　　Since TTP bus resource is less available than CAN bus, this thesis is started from designing their interface module board. The thesis puts emphasis on CAN bus architecture preliminary designs, system test and verification of communication protocol. The CAN IP board chosen from CAN controller SJA1000 and AT89C52 microprocessor is designed and fabricated with the human interface including data transmission and receiving control command. The IP board may also be connected to GPS module. This will contribute to an implementation for avionics data bus in general aviation aircraft.
