Abstract


With the development of modern science and technology , the increasing complexity of structure and function of the UAV , in order to ensure the safe and reliable flight before takeoff , the need to conduct a comprehensive inspection of UAV flight control system performance . Mobile automatic detection system it is suitable for this need , 1553B bus interface unit as an important part of the system , mainly to complete the 1553B bus design based avionics test and simulation functions . This paper focuses on the 1553B bus interface unit of the a mobile automatic detection system design and research . 1553B bus as avionics interconnect bus , and its domestic and foreign military aircraft widely used . CAN bus has a good price , in terms of reliability , real-time is relatively high , so the selection of the internal bus of the CAN bus as a mobile automatic detection system using a distributed architecture for easy system expansion upgrade . First, according to the characteristics of the mobile automatic detection system , the establishment of the design goals of the 1553B bus interface unit , the overall structure of the system . Second , to discuss the 1553B avionics bus design characteristics of the communication system , discusses the 1553B bus interface hardware design and software design based embedded operating system μCOS-II . Again , the formation of the 1553B bus communication test environment . In this environment , the research 1553B bus communication characteristics 1553B bus fault injection and error detection technology . Finally, according to the the 1553B bus topology , the flight control computer subsystem involves simulation testing environment constitute and testing program .
