Abstract: 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.
