The utility model discloses a digital twin
data management device, and belongs to the technical field of
industrial Internet of Things
data management. A multi-protocol conversion
chip is compatible with an RS485 interface, an
Ethernet interface and an
optical fiber interface, a PCIe interface is adopted to realize high-speed data interaction among a
processing module, a security module and a storage module, a dual-redundancy circuit is utilized to guarantee
verification signal transmission reliability, and hierarchical
data management is realized in combination with a hierarchical storage architecture (an SSD cache layer, an
RAID6
disk array layer and a distributed node layer). And the
data integrity is ensured through a
model checking unit (double-precision
floating point residual calculation) and a self-checking unit (CRC checking and
heartbeat packet detection) of the synchronous checking module. The method has the advantages that the protocol conversion
delay is smaller than or equal to 2 microseconds, the
encryption throughput of the SM4
algorithm reaches 5 Gbps,
RAID6 double-disk
fault tolerance and parameter updating
batch processing efficiency are improved by two times, the
system availability is larger than or equal to 99.999%, and the high-real-time, high-safety and high-reliability digital twin data management requirements in industrial scenes are met.
