An edge cache-based irrigation control system and a method for off-network self-execution and data synchronization thereof

Abstract

The application relates to an edge cache-based irrigation control system and a network interruption self-execution and data synchronization method thereof, which comprises a cloud platform layer for irrigation decision instruction generation, irrigation task issuing, offline log analysis, state fusion, irrigation deviation compensation, new plan generation and abnormality alarm pushing; an edge gateway layer for outputting device control signals based on irrigation decision instructions and providing network interruption autonomy, power interruption continuous running, data verification and local sound and light alarm functions; and a field device layer for collecting meteorological data, field environment data and irrigation operation data in real time, providing data support for cloud end decision and local abnormality judgment of the cloud platform layer and the edge gateway layer, and executing irrigation tasks according to the device control signals output by the edge gateway layer. The application can be widely applied in the fields of agricultural, garden irrigation automation and Internet of Things technology.
