浅析无人机软硬件余度设计方法

Analysis of UAV Software and Hardware Redundancy Design Method

随着无人机地位的不断提高,其安全性和可靠性愈发重要。本文从无人机工程实际出发,从硬件和软件两方面对无人机进行余度设计。在硬件余度设计方面详细列举和分析无人机作动部分、传感器和数据链部分,并对安全性影响较大环节进行余度设计;在软件余度设计方面,主要介绍了表决算法、同步算法和故障监控算法三种余度算法。

With the continuous improvement of the status of UAV,its safety and reliability are becoming more and more important.This paper starts from the actual UAV engineering,and designs the UAV redundancy from both hardware and software aspects.In terms of hardware redundancy design,the UAV action part,sensor and data link part are listed and analyzed in detail,and redundancy design is carried out for the links that have a greater impact on safety.In terms of software redundancy design,three redundancy algorithms of voting algorithm,synchronization algorithm and fault monitoring algorithm are mainly introduced.
