Radio frequency identification (RFID) sensing tag system for monitoring storage device status

Abstract

The invention discloses an RFID sensing tag system for monitoring storage device status. The system comprises an RFID sensing tag, a sensing tag receiver and a computer, wherein the RFID sensing tag comprises a magnetic induction sensor, a radio frequency chip, a micro control unit and a power supply, the radio frequency chip is used for sending and / or receiving wireless signals, the power supply is used for supplying power to a circuit, the magnetic induction sensor, the radio frequency chip and the power supply are respectively connected with the micro control unit, and an opening position on a storage device, which corresponds to the magnetic induction sensor, is coated with magnetic materials or a magnet is embedded in the opening position. By the aid of the system, real-time monitoring of the storage status of the storage device can be achieved, and the magnetic induction sensor is used for detecting the status of the storage device, so that the RFID sensing tag of the system can be used repeatedly, the system is very environment-friendly, and real-time monitoring can be achieved easily. The system is less in usage limit, wide in application range and applicable to various storage environments and various storage devices.

Description

Technical field [0001] The invention relates to an RFID sensor label system for monitoring the state of a storage device, in particular to an RFID sensor label system based on active RFID technology applied to the fields of security, logistics and transportation, and confidential document storage. Background technique [0002] With the development of electronic tags and sensor technologies, electronic tags can not only be attached to the items to be identified as electronic marks for the items to be identified, but also can be combined with sensors as a tool to monitor the state of the item storage device, such as using electronic tags and temperature sensors To monitor the temperature status of the food freezer or use electronic tags and humidity sensors to monitor the humidity status of the drug warehouse. The sensor tag converts the special physical state change signal detected by the sensor on the tag into a digital signal and sends it through radio frequency technology; the ...

Problems solved by technology

[0005] The anti-tampering electronic tag is an electronic tag with a weakened line. When using it, it needs to be pasted on the opening of the storage device. Once the storage device is illegally opened, the electronic tag will also be damaged along the weakened line, so that the electronic tag can no longer work normally. Infer that the corresponding storage device has been tampered with

Although the anti-tampering electronic tag can detect the illegal opening of the storage device, it cannot know the time of opening and cannot monitor in real time, and the electronic tag will eventually be damaged due to the normal opening of the storage device, so each electronic tag can only be used once

Although the use of light-sensing tags can record time and achieve real-time monitoring, but for illegal opening in the dark, the light-sensing tags will not play a role
