The embodiment of the invention relates to the technical field of data compression, and discloses a data compression method and device, a terminal and a computer readable storage medium. The data compression method comprises the following steps: dividing operation data generated by artificial influence weather flight equipment into a plurality of groups, wherein each group comprises the job data with the same attribute; respectively adopting a corresponding coding mode according to the attribute of each grouping operation data to form a coding stream corresponding to each grouping operation data, wherein each block coding stream comprises key information of operation data in the block; and combining the coded streams corresponding to the grouped job data to generate a data stream. According to the embodiment of the invention, the job data is grouped, the key information in the job data is coded by adopting the corresponding coding modes according to the attributes of the grouped job data, and finally, one data stream is obtained through splicing, so that one data stream contains some key information as much as possible, the job data with various attributes can be transmitted, and the transmission efficiency is improved.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of data compression, and in particular to a data compression method, device, terminal, and computer-readable storage medium. Background technique [0002] Artificial weather modification ("human shadow") aircraft, as an important means of operation to affect local weather operations, has the characteristics of strong real-time operation, wide flight area span, long flight time, and wide range of benefits. The scale of operation has also increased in recent years. It is constantly expanding and applied to various tasks such as fire suppression and drought relief, reservoir expansion, air quality improvement, and forest and grass ecological improvement. [0003] As a high-speed flying aircraft that can mount precision detection instruments and spreading devices, the weather modification aircraft is faced with a complex and changeable operating environment, and its flight process requi...
