Space-time big data converging system and method

Abstract

The invention discloses a space-time big data exchange system and method. The system comprises a static data exchange subsystem and a dynamic data exchange subsystem, wherein the static data exchangesubsystem comprises a first detection module for detecting different types of first trigger events and a first response module for executing a data exchange service corresponding to the current firsttrigger event when the first detection module detects the current first trigger event; the dynamic data exchange subsystem comprises a butt joint module used for achieving butt joint of the dynamic data exchange subsystem and an Internet of Things platform. The second detection module is used for detecting second trigger events of different types; and the second response module is used for subscribing Internet of Things data corresponding to the current second trigger event from the Internet of Things platform when the second detection module detects the current second trigger event. Accordingto the invention, the real-time performance of time-space big data updating can be effectively ensured.

Description

technical field [0001] The invention relates to the technical field of geographic information, in particular to a spatio-temporal big data collection system and method. Background technique [0002] From the development of geospatial framework to spatiotemporal information cloud platform, basic geographic information data has risen from static data to spatiotemporal big data with time stamp. The spatio-temporal information cloud platform of the smart city, by adding historical information, current information, real-time information and even various future planning information, integrates, integrates, operates and serves under the Internet of Things and cloud computing, and can reproduce continuous reality through digitization world, and can affect and react to the real world. [0003] In the process of implementing the present invention, the inventor found that in the current space-time information cloud platform, on the one hand, since the static data such as various geogr...

Problems solved by technology

[0003] In the process of implementing the present invention, the inventor found that in the current space-time information cloud platform, on the one hand, since the static data such as various geographic information data in the data center are regularly updated by various authoritative data departments, there is a long data update cycle. , The problem of slow update speed, which leads to low real-time data update; Data update, and the input and output standards of each IoT device are not uniform. Therefore, a lot of conversion work is often required in the process of obtaining IoT data, which takes a long time, resulting in low real-time data update.
