1394总线仿真系统设计与实现

Design and implementation of 1394 simulation system

随着1394总线在机载领域的广泛应用,出于低成本、灵活性考虑,地面配置、仿真、测试、监控、试验等环节急需建立一套完整的1394总线仿真测试系统。可靠的总线仿真系统可实现产品的模块级、系统级应用测试,同时最大程度地缩短系统研制周期,节省开发成本。提出一种1394总线仿真系统的设计方案,结合系统需求,从系统搭建、系统配置、系统监控与仿真及系统管理等进行详细介绍,建立全面、完备、可靠的仿真系统平台。可通过该平台对1394总线的通信机制、运行方式、工作原理以及系统应用进行深入研究,同时方便系统应用者进行故障检测、排查与设备维护,进而为机载设备的开发、验证、试验与应用提供可靠的技术保障。

As 1394 bus is widely used in the field on airborne, for low cost and flexibility consider, the process of surface configuration, simulation, testing, monitoring and test need to establish a complete set of 1394 bus simulation test system. Reliable bus simu-lation system can realize the product level and system level application testing, at the same time, shorten the system development cycle and save the development costs greatly. This paper proposes a 1394 bus simulation system design scheme, combinging with the system requirements with the detailed introduction of the system building, system configuration, system monitoring and simulation and system configuration, to establish a comprehensive, complete, reliable platform for the simulation system. Based on the platform, the further study of 1394 bus communication mechanism, operation mode, the working principle and system application can be achieved.It is easy for system developer to detect a failure, check and maintenance, and provides reliable technical support for the development, validation, test and application of airborne equipment.
