一种飞控系统参数管理的嵌入式解决方案

An Embedded Solution for Parameter Management of Flight Control System

飞行控制系统是一套复杂的嵌入式软件,经常要存储一些非易失参数,例如用户设置、校准参数、算法参数等,参数既是数据,又参与计算,是飞控软件不可或缺的部分。嵌入式环境中通常按照结构体的方式将全部参数保存在Flash中,但该方案扩展性较差且缺乏系统性,目前针对飞控系统参数管理方面的系统研究很少。提出了一套飞控系统参数管理的完整嵌入式解决方案,包括参数的定义、获取、更新、存储等,并设计了与上位机的参数通信协议。将该方案成功应用到某飞控系统,试验结果表明该参数管理方案完整、高效、可靠,并具备良好的扩展性。

Flight control system is a set of complex embedded software,which often needs to store some non-volatile parameters,such as user Settings,calibration parameters,algorithm parameters,etc.Parameters are not only data,but also participate in calculation,which is an indispensable part of flight control software.In embedded environment,all parameters are usually stored in Flash in the way of structure,but this scheme has poor scalability and lack of systemization.At present,there are few systematic researches on the parameter management of flight control system.Presents a complete embedded solution of flight control system parameter management,including parameter definition,acquisition,update,storage,etc.,and designs a parameter communication protocol with the host computer.The scheme is successfully applied to a flight control system,and the test results show that the parameter management scheme is complete,efficient,reliable and has good scalability.
