Multi-terminal data interaction method, device and equipment

The invention discloses a multi-terminal data interaction method, device and equipment, and the multi-terminal data interaction method applied to an adapter comprises the steps: obtaining original data of a data access terminal; performing data coding on the original data to obtain intermediate data; and transmitting the intermediate data to a data bus, so that when the data bus receives a query request and/or a subscription request of a data acquisition end, the data bus matches corresponding target data from the intermediate data for different keywords to execute a response. According to the method, the original data of the data access ends are obtained, the original data are coded according to the preset data format, and the intermediate data in the unified format is generated and transmitted to the data bus, so that data interaction between the multiple data access ends and the data acquisition ends is facilitated; in the access process, the data interaction between the data access end and the data acquis
