The invention relates to the technical field of
Internet of Things equipment management, in particular to a multi-equipment heterogeneous protocol operation method and
system based on an
Internet of Things platform. By constructing an analysis and
adaptation framework of a protocol analysis engine, a dynamic
object model library and a rule mapping engine, flexible expansion and
interoperability of a communication protocol between
Internet of Things equipment and a platform are realized, the development efficiency is improved, and the operation and maintenance cost is reduced. Dynamic access of multiple devices and multiple protocols is supported, and the access threshold is lowered. The dynamic
physical model library supports versioning management, and adaptive physical models can be dynamically bound according to different equipment models and function requirements. The configuration process of the
physical model is simplified, and the problem of protocol
adaptation explosion caused by static
physical model configuration is eliminated. The rule mapping engine realizes bidirectional
data conversion between a heterogeneous protocol and a physical model through a Grouping script, a data interaction link between multi-protocol equipment is opened, and the
cooperative work capability between the equipment is improved.
