A meteorological data sharing method, device and system based on a block chain

Abstract

The invention belongs to the technical field of the Internet and relates to a meteorological data sharing method, device and system based on a block chain. The meteorological data sharing method basedon the block chain comprises the following steps: the meteorological collecting node reports the sharing level, pricing strategy, geographic position of the meteorological collecting device with themeteorological data collecting ability, and at least one meteorological attribute of the meteorological data that can be collected; a query directory is generatedaccording to the geographic locationsregistered by all meteorological collection nodes and the corresponding meteorological attributes; the query directory is broadcasted; The meteorological demand node selects the meteorological attributes of the meteorological data of the meteorological collection node in the meteorological tracking target area according to the query directory, and requests to share the meteorological data. The meteorological demand node obtains meteorological data of the meteorological collection node in the target area according to a sharing level with the meteorological collection node in the target area. Itcan effectively realize the sharing of meteorological data, improve the accuracy of meteorological guidance and promote the application.

Description

technical field [0001] The invention belongs to the technical field of the Internet, and in particular relates to a block chain-based meteorological data sharing method and a block chain-based meteorological data sharing device and system. Background technique [0002] At present, the collection of meteorological data is carried out by various government departments, enterprises or individuals, and the collected data is scattered and has low precision. With the development of smart agriculture, autonomous driving and other industries, the demand for high-precision weather data is becoming more and more urgent. The resolution of public weather data sources is only about 10*10 kilometers. To obtain high-resolution weather data, it is necessary to install enough Dense high-precision weather stations. [0003] However, if government departments such as meteorology, agriculture, and transportation, industry enterprises, and even individual weather enthusiasts deploy weather coll...

Problems solved by technology

However, in the existing technology, the search for target data, data sharing or transaction negotiation process is cumbersome, and the sharing or transaction of multi-party meteorological data is difficult. It is difficult for small and medium-sized enterprises or individuals to join the transaction to realize data realization.
