Abstract: A many-to-many state identification system of equipment names broadcasted from Internet-of-Things comprises IoT nodes and IoT mobile devices connecting the IoT nodes wirelessly. Each IoT node receives the sensed value of transducer on a machine element, determining whether the sensed value of transducer is abnormal. Next, the IoT node broadcasts an equipment identification name containing an existing gateway identification code and a state code of transducer showing whether the transducer is abnormal.

Accordingly, before connecting the IoT mobile device to the IoT node, the state of transducer in the IoT node is acquired, allowing any IoT mobile device to monitor any transducer in a synchronous and many-to-many manner within the broadcasting area.
