Description

Radio frequency identification tracking device

The present invention relates to a tracking system, and more particularly to a radio frequency identification tracking device that combines a passive radio frequency identification (RFID) with a portable electronic device.

According to the current monitoring system on the market, satellite positioning (GPS) is mainly used in combination with GSM or 3G mobile communication. By the position of the monitored person moving, the GPS receiving satellite signal is sent to a specific receiver through mobile communication, such as Taiwan's new type. Patent No. M287479, which proposes a remote security guard device with timing information transmission, the device at least comprising: an input device, a reply device, a signal transceiver device, a clock module; according to a preset time, the user holds the digital position by hand The device 1 transmits the status of a currently handheld digital device to the monitoring center so that the monitoring center 60 can make appropriate processing based on the currently received status. However, once the device is in a place with poor GSM or GPS reception, it will not work. Moreover, the average person spends more time indoors, so GPS is bound to have a difficult effect, and it is too late to wait until the monitored or caregiver leaves the room to the outside to be effective.

Another common method of monitoring is through RFID, which is a non-contact automatic identification technology. It uses the RF signal to automatically identify the target and obtain relevant information. The operation is fast and convenient. The recognition action can be used to identify dynamic objects and identify multiple tags at the same time without manual intervention. A complete RFID system consists of a reader (Reader) and a Transponder. The identification controller is also commonly referred to as an RFID tag. The principle of operation of the RFID system is to first transmit a specific frequency of radio wave energy to the RFID tag for driving. The RFID tag sends an internal ID (ID Code) for the reader to receive the ID and send it to the central processing system for data processing. Current RFID applications include: logistics and supply management, manufacturing and assembly, terminal processing, mail and courier processing, file tracking and library management, animal identity identification, access control, electronic tickets and automatic charging, etc. . However, its so-called access control only reads and checks the identification code on the user's RFID tag through the reader, and does not have the function of tracking or recording the user's position within a certain area.

In fact, most of these devices are not available for users to use as a portable tracking, and are mostly fixed-point scanning, and can not be used as a home or personal monitoring function.
