Abstract
The invention aims to provide a power supply method for an RFID reader of the Internet-of-Things. With the method, power is supplied to the RFID reader of the Internet-of-Things by a 48V alternating current or direct current power source through an Ethernet cable. The method can achieve remote power supply in a UDP/TCP communication mode.
Description
Technical field
The object of the present invention is to provide a kind of RFID reader method of supplying power to of Internet of Things, the method is by powering by an Ethernet netting twine 48V interchange or DC power supply to RFID of Internet-of-things reader, the method can realize the remote power feeding of UDP/TCP communication modes.
Background technology
The object of the present invention is to provide a kind of RFID reader method of supplying power to of Internet of Things, the method is by powering by an Ethernet netting twine 48V interchange or DC power supply to RFID of Internet-of-things reader, the method can realize the remote power feeding of UDP/TCP communication modes.
Summary of the invention
For above object, the invention provides a kind of rfid interrogator of the POE of realization function of supplying power, this device comprises following operation requirements:
1. with UTP five class netting twines, realize UDP/TCP transfer of data, and on this netting twine, load 48V power supply provisioning RFID reader, adopt UDP/TCP majority according to communication interface mode.
2. the data communication of couple TCP/UDP and power supply definition: pin 1 is RX+, and pin 2 is RX-, and pin 3 is TX+, and pin 6 is TX-, and pin 4,5 is 48V power-level, and 7,8 pins are 48V positive source; If alternating-current feeding, 4,5 pin and 7,8 pin are extremely capable regardless of positive-negative power, and power supply obtains direct voltage by the rectification of RFID reader.
Accompanying drawing explanation
Fig. 1 is a kind of rfid interrogator method system construction drawing of realizing POE function of supplying power.
Embodiment
In the following detailed description, having described specific details comprehensively understands the present invention to provide.Yet professional and technical personnel will appreciate that, the present invention also can implement by other similar details.
Although the invention is not restricted to this, as a specific embodiment of the present invention.
1. with UTP five class netting twines, realize UDP/TCP transfer of data, and on this netting twine, load 48V power supply supply RF ID reader.Adopt UDP/TCP majority according to communication interface mode.
2. the data communication of couple TCP/UDP and power supply definition: pin 1 is RX+, and pin 2 is RX-, and pin 3 is TX+, and pin 6 is TX-, and pin 4,5 is 48V power-level, and 7,8 pins are 48V positive source.If alternating-current feeding, 4,5 pin and 7,8 pin are extremely capable regardless of positive-negative power, and power supply obtains direct voltage by the rectification of RFID reader.
Although herein declarative description certain this feature of the present invention and a kind of implementation method, for professional and technical personnel, will there will be many modifications, replacement, variation and equivalent substitution.Therefore, protection scope of the present invention is as the criterion by the scope of appended claim.
Claims (2)
1. a RFID reader method of supplying power to for Internet of Things, the method has following steps:
With UTP five class netting twines, realize UDP/TCP transfer of data, and on this netting twine, load 48V power supply provisioning RFID reader, adopt UDP/TCP majority according to communication interface mode.
2. as claim 1, narrate, it is characterized by: the data communication of TCP/UDP and power supply are defined: pin 1 is RX+, and pin 2 is RX-, and pin 3 is TX+, and pin 6 is TX-, and pin 4,5 is 48V power-level, and 7,8 pins are 48V positive source; If alternating-current feeding, 4,5 pin and 7,8 pin are extremely capable regardless of positive-negative power, and power supply obtains direct voltage by the rectification of RFID reader.
