Problems solved by technology

[0002] With the continuous application of RFID technology, the scale and application of RFID tags continue to increase, and the background application system needs to process more and more raw RFID data, and many of these raw data are useless or even wrong data. The application processing these redundant RFID data also increases the additional overhead of the system
Most of the RFID middleware on the market use software, and some use hardware. However, the system structure is complex and expensive, and it is difficult to adopt it in the RFID application system of small and medium-sized enterprises.

Embodiment Construction

[0014] In the following detailed description, specific details are described in order to provide a thorough understanding of the present invention. Those skilled in the art will recognize, however, that the invention may be practiced with other similar details.

[0015] Connect the device to the PoE power supply device (PoE switch) through an ordinary Category 5 network cable, and the device can obtain power without a separate power supply system.

[0016] Before the communication gateway is running, the background application system sets the RFID data format, filtering events and rules for the communication gateway through the Ethernet interface 2, and of course it can be modified at any time during the system operation.

[0017] After the RFID raw data collected by the RFID reader is transmitted to the Ethernet interface 1, the single-chip computer of the device first checks whether the format of the raw data is correct. If it is wrong, it discards it. If it is correct, it f...

Abstract

The invention provides a communication gateway device of an Internet of things. The device consists of an Ethernet interface 1, an isolating transformer 1, an Ethernet chip 1, a PoE module, an Ethernet interface2, an isolating transformer 2, an Ethernet chip 2, an embedded single chip microcomputer, and an LED display lamp. The device can support the PoE power supply, can be controlled by the application system, and can carry out the event driving and filtering of the RFID data.

Description

technical field [0001] The purpose of the present invention is to provide a communication gateway device for the Internet of Things, which provides power to the RFID reader through the Ethernet port, and can filter the data received by the RFID reader and send it to the application system. Background technique [0002] With the continuous application of RFID technology, the scale and application of RFID tags continue to increase, and the background application system needs to process more and more raw RFID data, and many of these raw data are useless or even wrong data. Application processing these redundant RFID data also increases the overhead of the system. Most of the RFID middleware on the market use software, and some use hardware. However, the system structure is complex and expensive, and it is difficult to adopt it in the RFID application system of small and medium-sized enterprises. Contents of the invention [0003] For the above purpose, the present invention ...
