The invention provides a UWB positioning and satellite positioning dual-fused greenhouse internal and external positioning system and method, and the method comprises the steps: firstly building a greenhouse internal positioning coordinate system through employing a UWB technology and an improved trilateral positioning algorithm, carrying out the optimization of an indoor positioning algorithm, obtaining a more accurate positioning coordinate, and achieving the autonomous navigation operation of agricultural machinery mobile equipment in a greenhouse; and providing satellite navigation data information of a greenhouse through a satellite navigation positioning module, and performing data fusion on a coordinate system inside the greenhouse and a GS84 coordinate system outside the greenhouse, wherein indoor and outdoor coordinate system formats are unified, indoor and outdoor positioning is automatically switched, and indoor and outdoor positioning systems are compatible. High-precision positioning is provided for operation of agricultural machinery mobile equipment, the problem of large non-line-of-sight positioning error fluctuation caused by a complex plant environment in a greenhouse is solved, meanwhile, the problem that indoor and outdoor positioning cannot be compatible is solved, the intelligent operation level of facility agricultural equipment is improved, and the productivity is improved.
Description
technical field [0001] The invention belongs to the technical field of positioning, and in particular relates to a positioning system and method for inside and outside of a greenhouse with double fusion of UWB positioning and satellite positioning. Background technique [0002] With the rapid development of sensor technology, 5G mobile communication technology and artificial intelligence technology, the transformation of agricultural machinery and equipment from manual operation to automatic operation has been accelerated. Sensor technology fills the lack of sensory systems of agricultural machinery, mobile communication technology increases language communication capabilities for agricultural machinery, and artificial intelligence technology undoubtedly becomes the brain of agricultural machinery, coordinating various sensory systems and language systems, and realizing agricultural machinery. Intelligent. However, when agricultural machinery and equipment move, the positio...
