Electronic tag reading and writing system and method based on multiple connection modes

Abstract

The invention provides an electronic tag reading and writing system based on a multiple connection modes. The electronic tag reading and writing system comprises a reading and writing terminal, a remote server and a mobile terminal. The reading and writing terminal is composed of a WIFI communication module, a Bluetooth module, a USB interface module, an electronic tag reader-writer, a microcontroller and a data storage module, the reading and writing terminal is in communication with a control center through the WIFI communication module or the Bluetooth module or the USB connecting module and is in communication with the mobile terminal through the WIFI communication module or the Bluetooth module or the USB interface module. The invention further provides a reading and writing method based on the system, the reading and writing functions of an electronic tag and the anti-crosstalk function among a plurality of non-contact type electronic tags within the reading and writing range are achieved. The system and method overcome the distance limitation on different management objects in the Internet of Things, meanwhile, a display screen and a keyboard at the reading and writing terminal are omitted, data can be input and displayed through the keyboard and screen resources of the mobile terminal, and therefore the system cost can be greatly reduced.

Description

technical field [0001] The invention relates to an electronic tag reading and writing system and a reading and writing method based on a multi-connection mode, and belongs to the technical field of electronic tag reading and writing. Background technique [0002] The development of electronic communication technology has greatly promoted the development of electronic tag technology and Internet of Things technology. The Internet of Things technology is based on electronic tags. Electronic tags include contact electronic tags and non-contact electronic tags. Each Internet of Things management object needs Configure at least one electronic tag. To realize the management of the Internet of Things, the core is the management of the electronic tag. [0003] In the current electronic tag reading and writing system, most of the reading and writing devices display the electronic tag information on the display of an external computer through a wired connection and input data to the r...

AI Technical Summary

Problems solved by technology

However, there is no electronic tag reading and writing device that can provide multiple connection methods at the same time to meet different applications.

[0005] In addition, the reading and writing equipment for non-contact electronic tags in the prior art usually requires that there is one non-contact electronic tag within the reading and writing range. If there is more than one non-contact electronic tag, it may lead to unrecognizable or wrong consequences of reading and writing errors
