Ethernet power supply sensor network

Abstract

The invention relates to the field of Ethernet data transmission. The invention relates to an Ethernet power supply sensor network and provides an Ethernet chain-shaped or ring-shaped data transmission network which is simple in wiring and high in reliability, is not interfered by outside, and is applied to chain-shaped and ring-shaped power supply structures of Ethernet power transmission. The Ethernet power supply sensor network is in a chain-shaped or ring-shaped structure, wherein the chain-shaped comprises primary power supply equipment and a plurality of powered equipment which are connected by the Ethernet in series to form a chain-shaped data communication structure; the ring-shaped structure comprises primary power supply equipment and a plurality of powered equipment which are connected by the Ethernet in series to form a ring-shaped data communication structure; and the power supply utilizes an Ethernet power supply way, and the data transmission and the power supply utilize the same Ethernet wire. The Ethernet power supply sensor network disclosed by the invention has the advantages that the power supply and the data transmission share the same transmission wire. The wiring is convenient and the wiring cost is saved.

Description

technical field [0001] The invention relates to the field of Ethernet data transmission in the internet of things. Background technique [0002] At present, data transmission in the Internet of Things includes wired data communication and wireless data communication. Due to the wide variety of fieldbuses in wired communication technology, there is a huge amount of deployment, and data collection in the Internet of Things generally distributes many and wide collection points, but the data The amount is not very large. If conventional wiring is used, wiring is often difficult and costly, and resources are seriously wasted. However, if wireless communication is used, the reliability is poor, and it is easy to be interfered by the outside world, which has a great impact on the safe transmission of data. [0003] Ethernet applications are mainly point-to-point or tree-shaped applications at present, but this connection method has no protection function for data transmission, and...
