Problems solved by technology
Data consuming organizations need to combine the data streams of multiple data generating organizations, but only part of the data in a single data stream is used, so a lot of manpower is required to filter and aggregate data across data streams
Therefore, the existing technical solutions cause a waste of bandwidth and require very high labor costs

Embodiment Construction
[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.
[0030] It should be noted that the "data producer" and "data application party" in the present invention are respectively used to refer to the IoT data platform that generates data and applies data, which can be converted to each other in different actual application situations. In other words, in a single data service process, the IoT data platform that sends the data stream is the data producer, and the IoT data platfor...

The invention relates to a data sharing method for a smart city, which comprises the following steps: S1) an IoT data platform in a smart city subsystem sends registration information to a data intermediation server in a cloud data service platform for registration of a data service; S2) after receiving the data service request, the data intermediation server divides the related IoT data platforminto a data producer and a data application party according to the data service request and the registration information; S3) the data mediation server pairs the data application party and the data producer satisfying the demand thereof, and the data producer establishes a peer-to-peer connection with the data application party; S4) the data intermediation server enables the data producer to selectively send the data field to the data application party according to the data demand information, and the data application party assembles the received data fields of a plurality of data streams intoa single target data stream for specifying smart city applications. The data sharing method for a smart city in the invention can effectively save bandwidth resources and reduce related labor costs.
Description
technical field [0001] The invention relates to the fields of the Internet of Things and data processing, in particular to a data sharing method for smart cities. Background technique [0002] Smart city is the product of the combination of Internet of Things and digital city. It provides intelligent analysis and intelligent services on the basis of urban big data, and studies the collection, storage and analysis and processing technology of large amounts of data in smart cities. It is of great importance for smart city data mining and smart decision-making. meaning. At present, urban data are mostly distributed in the original information systems established by various departments. After data extraction, they are aggregated to the data center for comprehensive analysis services. However, the aggregated and integrated data will often have difficult matching, inconsistency, and information redundancy. Therefore, from the perspective of overall management and application of u...
