RFID-based wireless router

Abstract

Disclosed in the invention is an RFID-based wireless router comprising a power supply circuit, a power-on reset circuit, a network processor, a network transformation chip, a transformation control chip, a first network isolation chip, a second network isolation chip, a serial interface, a data memory, an indicator light circuit, a power supply circuit, an RFID middleware and an RFID reader. The wireless sensor network and the RFID are combined, so that the data transmission distance is long and the node position can be located accurately; and the cost is saved.

Description

Technical field [0001] The present invention relates to a router, in particular to a wireless router based on RFID. Background technique [0002] RFID and wireless sensor networks are two popular technologies for acquiring wireless information. The Internet of Things can be simply described as information perception + communication network + information processing. The information perception layer is the core of the Internet of Things industry, and the RFID wireless sensor network is the thing A typical form of the networked perception layer. The fusion of RFID and wireless sensor networks is inevitable. First of all, because RFID tags have the ability to uniquely identify objects, they can sense the temperature, humidity, and light status information of surrounding objects and the environment by combining with wireless sensor networks, and use wireless communication technology to transmit these status information and changes. To the computing unit, thereby improving the visibi...

Problems solved by technology

First of all, because RFID tags have the ability to uniquely identify objects, they can sense the temperature, humidity, and light status information of surrounding objects and environments by combining them with wireless sensor networks, and use wireless communication technology to transmit these status information and their changes. to the computing unit, so as to improve the visibility of the environment to the computing module; secondly, the wireless sensor network generally does not care about the location of a certain node, so the global identification of the node is generally not used, and the RFID technology has a unique advantage in the identification of the node. The combination of the two forms a network that can make up for each other's shortcomings. It can not only make the network take into account the information of a specific node, but also use the identification function of RFID to easily find the location of the node; Generally less than ten meters, which is a limitation for its application
