The invention discloses an
Internet of Things data integration method and
system based on dynamic semantic atlas and edge
collaboration, and the method comprises the steps: carrying out the equipment access and protocol conversion, capturing the
original data of equipment through an
edge node, analyzing the average communication interval of 100ms + / -20ms through an LSTM model, generating an equipment
fingerprint hash value, analyzing a
message structure through a TinyBERT model, and extracting a key field, a temperature value and a
timestamp. The method comprises the following steps: establishing a dynamic semantic graph, converting the dynamic semantic graph into a standard
JSON format, uploading the standard
JSON format to a cloud end through a
service grid, constructing a dynamic semantic graph, collecting multi-source
metadata by the cloud end, generating an entity relationship by utilizing a Transform model, dynamically optimizing a mapping rule based on
reinforcement learning, automatically associating a Pressures field to a
database column PSI, and carrying out collaborative optimization by an edge cloud; according to the method, the
knowledge graph and the Transform model are combined, the
data entity relation is updated in real time, the semantic drift problem of a traditional static graph is solved, the cross-domain
data association accuracy is improved by 35%, the unique
device fingerprint is generated through the message frequency and
load distribution, and dynamic tracking of the
mobile device is supported.
