The communication method includes: each slave sends a report signal to a host, and monitors a response signal of the host; and if the at least one slave receives the response signal, the corresponding slave executes a corresponding action on the basis of the response signal. Therefore, communication between the host and each slave is achieved in a mode that each slave actively sends the report signal, the host is prevented from adopting a roll call query mode, and occupation of bus resources by the host is reduced.
