BDS在陆地智能巡检无人车中的应用

当前智能化产品转型升级，无人车已广泛应用于生产生活实践中并发挥巨大作用. 北斗卫星导航系统(BDS)作为国产化的先进定位导航系统，在国产化智能产品的转型升级过程中将发挥越来越重要的作用. 智能化的巡检小车需具备自动导航定位和环境感知功能，而定位导航模块与通信模块扮演着重要角色. 本文设计一种适用于陆地各地形场景的智能巡检无人车，采用BDS进行定位，基于多传感器信息融合感知外部环境，能够实现自动巡航和避障相关功能，应用了BDS模块独特的短报文系统构建上位机平台进行信息交互传输，达到了良好的人机交互效果. 通过试验证明了系统的可靠性，能够进行无人车的自动巡航且巡检路径基本与预期路径保持一致. 以BDS模块为核心的无人巡检小车搭载各种功能模块后，可打造出系列相关产品用于社会生产实践中，为后续的相关技术的拓展提供新思路. 

Application of BDS in unmanned vehicle for land-based intelligent inspection

The current transformation and upgrading of intelligent products, unmanned vehicles have been widely used in production and life practice and play a huge role. BeiDou Navigation Satellite System (BDS), as an independent localized advanced positioning and navigation system, will play an increasingly important role in the transformation and upgrading process of localized intelligent products. The intelligent inspection trolley needs to have autonomous navigation and positioning and environment awareness functions, and the positioning and navigation module and communication module play an important role. This paper designs a kind of intelligent inspection unmanned vehicle which is suitable for terrain scenes on land, adopts BDS satellite positioning system for positioning, senses the external environment based on multi-sensor information fusion, can realize the functions related to autonomous navigation and automatic obstacle avoidance, applies the unique short message system of BDS module to build the upper computer platform for information interaction transmission, and achieves good human-computer interaction effect. The reliability of the system is proved through the test, and it can carry out the autonomous cruise of the unmanned vehicle and the inspection path is basically consistent with the expected path. The BDS module as the core of the unmanned inspection vehicle equipped with various functional modules can create a series of related products for social production practice, which provides new ideas for the subsequent expansion of related technologies.
