Internet of Things operating system platform communication method and system based on soft bus

The invention provides an Internet of Things operating system platform communication method and system based on a soft bus, and the method comprises the steps: constructing a soft bus frame based on a multi-communication protocol stack; an MQTT Broker instance is agented through an agentive cluster to establish communication between the soft bus framework and an Internet of Things operating system, an edge device and a sensing device; maintaining a stickiness table of the user identifier and the proxy node through the stickiness session so as to bind the subscriber and the MQTT Broker instance; authenticating a service provider through an equipment authentication component, and discovering the service provider through an equipment discovering component so as to establish communication between a service consumer and the service provider; and identifying the abnormal message based on the state monitoring component, and retransmitting the abnormal message through the message persistence component.
