A distributed internet of things terminal system and method based on optical fiber bus rof

Abstract

The invention discloses a distributed Internet of Things terminal system and method based on optical fiber bus RoF, which is characterized in that it includes a core application part, a front channel part, a transmission channel part, an acquisition site part, an acquisition terminal part and a data source; The invention adopts the principle of optical radio frequency ROF to adapt to pan-socialization, decentralization, verticalization, refinement, full traceability, and full life cycle management and governance, instant, real-time, online, interactive, and distributed IoT applications ; The integrated application of the present invention improves social efficiency and saves social costs; it can be integrated and applied to any application system to realize dynamic instant and real-time online centimeter-level positioning applications; the specific position of the positioning device can be inferred; the present invention combines ROF and The combination of RFID technology, as well as the combination of high-speed bus and RFID technology, solves the "last mile problem" of RFID and physical online and offline applications.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, in particular to a distributed Internet of Things terminal system and method based on an optical fiber bus RoF. Background technique [0002] Problems in the existing radio frequency RFID reading and writing system: the area covered by the signal is limited by the number of readers, the transmission distance of copper twisted wires and the number of antennas deployed, and the cost of system deployment increases with the area covered by the signal, and the number of readers The increase in the number of applications restricts and restricts the deep integration of physical and online applications, restricts and restricts the further extensive application of the combination of labels and products, and restricts and restricts the personnel, equipment, objects and products identified by labels , In the procurement link, production link, circulation link, warehousing logistics, r...

[0002] Problems in the existing radio frequency RFID reading and writing system: the area covered by the signal is limited by the number of readers, the transmission distance of copper twisted wires and the number of antennas deployed, and the cost of system deployment increases with the area covered by the signal, and the number of readers The increase in the number of applications restricts and restricts the deep integration of physical and online applications, restricts and restricts the further extensive application of the combination of labels and products, and restricts and restricts the personnel, equipment, objects and products identified by labels , in the procurement link, production link, circulation link, warehousing logistics, retail link, distribution link, real-time, real-time online fine management, real-time, real-time online precise management and application in a wide range at any time and any place

However, it does not have long-distance communication capability and poor anti-interference ability, so it is not easy to integrate into other positioning systems
