Reliable transmission technology of massive heterogeneous information in complex environment of public buildings

The rapid development of Internet of Things (IoT) devices in public buildings has raised higher requirements for the reliable transmission of vast amounts of heterogeneous information. Through analyzing the communication status and requirements of devices at different levels in complex environments, this paper proposes an application scheme for public buildings based on the technical architecture of "intelligent terminal + IoT communication unit", which consists of high-speed power line communication and high-speed wireless communication. It realizes the key technologies such as dual-mode network and relay used to improve communication quality. By comparing the communication effects of the dual-mode communication scheme with traditional schemes, the reliability and superiority of the dual-mode communication technical scheme are verified.
