Embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, to the embodiment of the present invention
In technical scheme be explicitly described, it is clear that described embodiment is part of the embodiment of the present invention, rather than all
Embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art institute under the premise of creative work is not made
The every other embodiment obtained, belongs to the scope of protection of the invention.
Fig. 1 is the schematic diagram according to a kind of searching article system of the embodiment of the present invention, as shown in figure 1, including：It is hand-held to visit
Survey terminal 1 and at least one electronic tag 2；Wherein,
Hand-held detecting terminal 1 is used to generate cognizance code for the electronic tag 2, and for sending inquiry code, connects
The response message that the electronic tag 2 feeds back is received, to determine the azimuth-range information of the electronic tag 2；
Electronic tag 2 is used to receive the inquiry code, and response message is sent after being matched with the cognizance code.
Wherein, electronic tag is pasted onto above the article for needing to find.
Frequency range conventional RFID include low frequency (30~300KHz), high frequency (3~30MHz), hyperfrequency (433MHz, 862~
928MHz) and microwave (more than 2.5GHz).According to operating distance, the additional category of radio-frequency recognition system：Close coupling conjunction (0~1cm),
Distant coupling (0~1m) and long range systems (1~10m).Because hyperfrequency have operating distance it is remote (under passive states up to 10m with
On), message transmission rate it is high (substantial amounts of electronic tag can be read in the short time), it is preferable that use in embodiments of the present invention
Frequency range is hyper band, using long range systems.
