The invention discloses an equipment fault
information sharing system and method based on
the Internet of Things, and relates to the technical field of equipment fault sharing. Causal relationships among parts, faults and operation parameters are identified, real-time operation data, historical fault data and maintenance records are integrated, association relationships among various types of data are combined, a fault
knowledge graph is constructed, and fault
information sharing is performed. Reasoning is executed through a
rule engine in the
knowledge graph, possible fault causes are deduced, and cross-
modal fusion is performed on fault phenomena, parameter changes and historical records to obtain a more accurate fault cause reasoning result. According to the sharing
system, after the parts, the operation parameters and the fault types of the electric
water heater are associated, the comprehensive fault
knowledge graph is constructed, so that when the electric
water heater breaks down, the parts which possibly have abnormity can be displayed to maintenance personnel after reasoning, the maintenance efficiency is improved, and the maintenance cost is reduced. And the use safety of the electric
water heater after maintenance is guaranteed.
