Design and Implementation of ARINC429 Bus Experimental System Based on SMHK1016
ARINC429 bus is a kind of data bus which is widely used in aviation field.In order to meet the needs of in-depth teaching and research on the communication principle and electrical characteristics of the airborne ARINC429 bus,a bus experi-ment system which is suitable for students of different majors and different foundations to carry out multi-level experiments has been designed and implemented in this paper.In order to solve the problems of the existing ARINC429 bus experimental system,such as low integration,poor testability,high cost and non intuitive experimental system,the ARINC429 bus experimental system with inte-grated display and control is designed,which adopts the system architecture of core board and bus interface board.The bus interface board is based on the domestic SMHK1016 chip and adopts modular design,which is helpful for replacement and maintenance.With the STM32 micro as the core,the core board realizes display and control human-computer interaction,ARINC429 protocol chip control and MPU6050 attitude sensor driver.The application shows that the experiment system is fully functional,which can provide hardware support and software interfaces for open experiments,and can effectively support ARINC429 bus practice teach-ing,so as to improve students'engineering practice ability.
