The invention relates to the field of technical
data acquisition, and particularly discloses a
data acquisition method and device for an
industrial Internet of Things and a storage medium, and the method comprises the following steps: S1, constructing a dynamic sensor network, and collecting the operation data of
industrial equipment in real time through a multi-
modal sensor; s2, dynamically adjusting a
data acquisition frequency # imgabs2 # based on an environment
noise coefficient # imgabs0 # and an equipment
health index # imgabs1 #; s3, performing hierarchical compression and
encryption on the acquired data, and allocating a compression rate # imgabs4 # and
encryption strength # imgabs5 # according to
data type importance # imgabs3 #; s4, executing load balancing through an
edge computing node, and distributing a computing task to an optimal node; and S5, storing the processed data into a
distributed database according to spatial-
temporal correlation, and generating a multi-copy
disaster recovery index. Through dynamic acquisition, intelligent
processing, optimized storage and adaptive strategy adjustment, accurate and efficient data acquisition is realized,
data security and
processing performance are flexibly guaranteed, storage query efficiency and disaster tolerance capability are improved, and storage resources are utilized to the maximum extent.
