Children anti-lost method of children monitoring system based on RFID

Abstract

The invention discloses a children anti-lost method of a children monitoring system based on RFID. The children monitoring system includes an RFID card reading module, a control module, a wristband module, a display module and an alarm module, wherein the wristband module includes a plurality of wristbands; each wristband includes a wristband body, a temperature sensor, a microcontroller and an RFID tag; the microcontroller is electrically connected with the temperature sensor and the RFID tag; the control module is electrically connected with the RFID card reading module, the display module and the alarm module; during the operating process, the control module extracts identity information and body temperature of a corresponding child in a received signal of the RFID tag in each wristband, calculates the coordinates of the child, relative to the RFID card read module, and controls the display module to display; and when a child whose body temperature is not in the preset body temperature range or whose coordinates are into in the preset range of coordinates, the information and the coordinates of the child are displayed in a highlighted way, and the alarm module is controlled to give an alarm. The children monitoring system can effectively avoid losing children.

Description

technical field [0001] The invention relates to intelligent equipment, in particular to an RFID-based child monitoring system. Background technique [0002] Radio Frequency Identification (RFID) is a wireless communication technology that can identify specific targets and read and write related data through radio signals without the need for mechanical or optical contact between the identification system and specific targets. [0003] Radio signals transmit data from a tag attached to an item through an electromagnetic field tuned to a radio frequency to automatically identify and track the item. Some tags can get energy from the electromagnetic field emitted by the identifier during identification, and do not need batteries; there are also tags that have their own power supply and can actively emit radio waves (electromagnetic fields tuned to radio frequencies). Tags contain electronically stored information and can be identified within a few meters. Unlike barcodes, RFID...

Problems solved by technology

5. Penetrating and barrier-free reading

6. Large data memory capacity

[0008] At present, there are many public places for children to play. When various activities are held, due to the unfamiliarity of the personnel, the scene is relatively chaotic, and it is easy for children to get lost.

[0009] Even with the equipped video surveillance system, it is difficult to make timely notifications for such situations
