基于自定义协议的机载数据记录仪控制系统设计

Design of Control System for Airborne Data Recorder Based on User-defined Protocol

针对机载数据记录仪特殊设计要求,结合仪器特点、特殊工作环境,该文设计了基于自定义协议的机载数据记录仪控制系统。采用自定义指令来实现各通道记录模块的控制管理以及存储数据的快速上传。机载数据记录仪采用上位机控制与1553B总线数据流双模式控制设计。基于自定义协议的控制管理系统具有系统简洁、通用性开放性强、控制模式灵活、可靠性高等优势,为数据记录仪系统体系结构的标准化和通用化方面以及系统管理机制提供一种解决方案。

In view of the special design requirements of airborne data recorder,combined with the use of airborne data logger features,special working environment. Design the control system for airborne data recorder based on user-defined command. The control and management system uses non-standard custom internal bus to realize the control and management of the each channel recording modules and fast read back later. It has two control modes of the host computer and the 1553 B bus data flow. The control system which based on user-defined protocol has the advantages of simple system,versatile and open,flexible control mode and high reliability. It provides a solution for the standardization and generalization of the system architecture of data recorder system and the system management mechanism.
