Abstract
The invention discloses a distributed IoT terminal system and method based on a fiber optic bus RoF. The system comprises a core application part, a pre-channel part, a transmission channel part, an acquisition field part, an acquisition terminal part and a data source. The invention adopts the principle of light-borne ROF to adapt to pan-socialization, decentralization, verticalization, refinement, full traceability, full lifecycle management and governance, instant, real-time, online, interactive and distributed IoT applications. The integrated and integrated application of the invention improves social efficiency and saves social cost. It may be integrated and integrated the application into any application systems, and realized dynamic instant, real-time, online, centimeter level positioning application. It can infer the specific location of the positioning device. The invention combined ROF and RFID and combined high-speed bus and RFID technology to solve the “last mile problem” of RFID and physical offline applications.
