High Performance UAV Data Retrieval Algorithm Based on Bit Vector Segmented Hash

This paper mainly studies the application of a high-performance retrieval algorithm under massive data. To solve the challenges faced by the growing UAV patrol data, nearly 0.5TB per month, we put forward a high-performance query algorithm for massive patrol data. Based on bit-vector hash table, the algorithm achieves high-performance data retrieval by adapting the data structure, such as inspection location, voltage class and defective part. Experiment shows the algorithm can achieve data retrieval with low delay, high reliability and low memory occupation under tens of millions of data, meeting the growing demand for UAV data management.
