  • development of a cross compatible micro Avionics System for aerorobotics
    IEEE Intelligent Vehicles Symposium, 2007
    Co-Authors: T Mutlu, Sertac Karaman, S Comak, Ismail Bayezit, Gokhan Inalhan, Levent Guvenc
    Abstract:

    In this work, we present a micro-Avionics System structured around the controller area network (CAN) bus data backbone. The System is designed to be cross-compatible across our experimental mini-helicopters and ground vehicles, and it is tailored to allow autonomous navigation and control for a variety of different research test cases. The expandable architecture deploys a hybrid selection of COTS Motorola (MPC555) and Arm processor boards (LPC2294), each with different operating Systems and coding techniques (such as rapid algorithmic prototyping using automatic code generation via Matlab/Real Time Workshop Embedded Target). The micro-Avionics System employs a complete sensor suite that provides real-time position, orientation and associated time-rate information. As a part of the on-going fleet autonomy experiments, we present the design of a novel wireless SmartCan node. This wireless node allows seamless CAN Bus access of low-level sensor and operational data of other vehicles within close proximity.

    Abstract:

    Abstract The organization architecture of the Avionics System is a System organization architecture oriented to System applications, System functions, and System resource requirements, which builds organization of System capabilities, System processes, and System performance, to achieve System application goals, System function processing, and System resource operations. The Avionics System architecture is a flight application mode based on multiple applications, multiple objectives, and multitype tasks. It covers the System functional capability with a wide range of disciplines, multitype domains, and multiple capabilities, supporting the Systemic organization of multiple resources, multiple environment, and multiple performance resource operations, and it provides the flight application task organization mode and architecture, System functional processing and architecture, and System physical resource organization mode and architecture.

Section 2.2 discusses the hierarchical organization of applications, functions, and resources. Finally, Section 2.3 further discusses the organization mode of the hierarchical Avionics System, including task, function, and physical equipment as well.

  • The integrated architecture of typical Avionics Systems
    The Principles of Integrated Technology in Avionics Systems, 2020
    Co-Authors: Guoqing Wang, Wenhao Zhao
    Abstract:

    Abstract Typical Avionics System integration architecture describes representatives of typical engineering integrated technical architecture in the development history of Avionics Systems. Through the balance between technological advancement and technological effectiveness, the balance between System organization and System complexity, and the balance between application requirements and development costs, the typical representatives of Avionics System integration technology architecture are formed: the federated System architecture, integrated modular Avionics (IMA) System architecture, and distributed integrated modular Avionics (DIMA) System architecture. Chapter 8 can be divided into three sections where it introduces the federated, IMA, and DIMA System integration one by one. Section 1 discusses that the federated System architecture is based on the digital technology, bus technology, and software technology capabilities at that time, and the application tasks of the System with different equipment are integrated. Section 2 describes that the IMA System architecture is based on the System general computing platform, hosted System application integration, and System network organization technologies to realize the integration of tasks based on IMA platform resources, IMA System functions, and Avionics System applications. And Section 3 describes that the DIMA System architecture is a distributed technology based on the application distributed organization, function distribution processing, and resource distribution operations of the System to achieve the task mode integration, function capability integration, and resource operation integration of Avionics System.

    Abstract:

    Avionics System integration is a System technology through which can improve the effectiveness of the System task, the efficiency of System function and the availability of resources operating.

  • Research on Integrated Avionics System Safety
    Proceedings of the First Symposium on Aviation Maintenance and Management-Volume I, 2014
    Co-Authors: Guoqing Wang, Miao Wang, Lihua Zhang
    Abstract:

    System safety is the principal driver of Avionics System requirements and has caused more and more attention. For the reason that the main concern of Avionics System research is System capacity and constitution since early safety analysis, System reliability has become dominant trends for studying System effectiveness. With the Avionics System becoming more and more complex, the traditional research methods which are used in studying System reliability, faces the challenges of organizing problem for multiple System goals, multiple processes, multiple elements, multiple relations, and multiple conditions. To solve the problem of safety analysis for integrated Avionics System, hazard and mishap modes of Avionics System are studied and the methods of risk analysis, risk evaluation, risk controlling, risk elimination, and risk mitigation are presented based on the System risk controlling theory. Finally, the organizing and engineering technologies of System safety, software safety, and hardware safety are also discussed to provide foundation for designing integrated Avionics System safety.

  • Communication performance analysis of Scalable Coherent Interface
    2011 IEEE 2nd International Conference on Computing Control and Industrial Engineering, 2011
    Co-Authors: Zhang Jiandong, Wu Yong-le, Shi Guoqing
    Abstract:

    In the designing process of the integrated Avionics System, the bus System performance is closely related to the overall index of the entire Avionics System. Scalable Coherent Interface (SCI) possesses some advantages, such as low latency and high bandwidth, and it can also meet the interconnection requirements within a System and between Systems, which makes it applicable to various key operations. This paper researches the SCI multi-ring simulation problem. It starts from the SCI protocol, and uses Petri nets as a tool to establish an exchange unit model and the System model. At last it is found that the simulating and solving of the System model can derive the relationship between System throughput and delay time.
