Power Internet of Things communication method and system

The invention belongs to the field of Internet of Things communication, and particularly relates to a power Internet of Things communication method and system. Each of the information sending module and the information receiving module comprises a plurality of communication sub-modules which correspond to different channels and communication modes, equivalently, a plurality of standby communication channels are arranged, and communication failure is effectively prevented; setting a communication self-checking module based on a heartbeat mechanism, and judging whether the current channel connection is smooth or not according to a set reference value and the heartbeat signal sending speed in the current communication mode; if it is judged that the connection is not smooth, the communication mode is reselected, whether unsmooth information transmission exists in the communication process or not is judged in time, the channel with unsmooth information is replaced with the channel with the optimal transmission eff
