Abstract
In view of the paucity of hydrometeorological data, inefficiency and high cost of manual detection, a design scheme of meteorological monitoring unmanned surface vehicle (USV) based on STM32 MCU (Microcontroller Unit, which is also known as Single Chip Microcomputer) is proposed in this paper. The path planning is designed by combining the image data acquired by camera with improved RRT-path algorithm (rapidly-exploring random tree algorithm based on auxiliary path), and then motors are controlled so as to realize autonomous cruise control of USV using the incremental PID algorithm. In addition, the design can also realize real-time monitoring of meteorological data detected by meteorological sensors on the USV through upper computer. Compared with the traditional scheme, the path planning, autonomous cruise is as well as online monitoring function of the scheme presented below enable USVs have full autonomous capability to realize on-line monitoring of meteorological data.
