Internet of Things communication method special for converter, Internet of Things system and equipment

The invention provides an internet-of-things communication method, an internet-of-things system and equipment special for a converter, and relates to the field of converter internet-of-things, and the specific scheme is as follows: center equipment obtains precise time through a satellite, and then synchronizes the precise time to all terminal equipment in the internet of things to complete time synchronization; after time synchronization, based on a multi-node communication transmission protocol, data interaction is carried out among the devices; the invention provides a time synchronization algorithm special for the converter, so that all converter equipment in a network has a synchronous clock, and meanwhile, the communication delay is greatly reduced; and a multi-node communication transmission protocol is designed, so that the communication delay between converter equipment is reduced, and the communication efficiency of the Internet of Things is improved. 本发明提出了一种专用于变流器的物联网通信方法、物联网系统及设备，涉及变流器物联网领域，具体方案包
