Embodiment
Below in conjunction with drawings and Examples embodiment of the present utility model is further described in detail, but should limit protection range of the present utility model with this.
Fig. 3 is the radio frequency identification read-write system schematic that comprises the utility model intelligent reader antenna.As shown in Figure 3, the utility model reader antenna, comprise parallel to each other, by ground plate 30 and radiation fin 31 that nylon screw links to each other, described ground plate 30 and radome are connected and fixed by two-sided tape 36.This reader antenna also comprises impedance matching unit 32, hang down and to have realized the impedance matching and the feed of reader antenna as for the feed lines 33 of ground plate 30, the holding wire feed lines 34 that are parallel to the coaxial cable of ground plate 30.
This reader antenna also comprises the electronic tag 37 between described ground plate 30 and radome.This electronic tag 37 is attached to above the described two-sided tape 36, below the radome.This electronic tag 37 can also stick on described radome and ground plate 30 non-contacting parts, as ground plate 30 top, as described in the inside of radome.Reader antenna is connected by coaxial cable 38 with reader 39.General reader 39 is connected by wired or wireless mode with computer 310.Electronic tag 37 is in test pattern, does not read this electronic tag 37 like this when reader 39 reads other normal mode electronic labeling information.
The utility model reader antenna is a super high frequency radio frequency identification reader antenna, and its working condition is as follows:
The super high frequency radio frequency identification electronic tag 37 that will be in test pattern is fixed on the utility model super high frequency radio frequency identification reader antenna.Reader 39 at first is operated in test pattern, detects on the reader antenna whether electronic tag 37 is arranged.If no, think that then this port of reader 39 does not connect antenna, reader 39 stops to send signal, provides the caution that this port does not connect antenna, thereby has realized the reader antenna self check.When reader 39 is read the data of electronic tag 37, again working mode change is become normal pattern.Computer 310 that is connected with reader or reader 39 self are controlled the transfer process of above-mentioned reader mode of operation, send at reader, the received signal number of times reaches some, such as 100 times, perhaps reader sends, received signal reaches certain hour, for example 30 seconds, can repeat once more once, carry out the reader antenna self check, prevent reader antenna and reader bad connection.Adopt electronic tag that the connection of reader antenna is checked, it still is that short circuit does not have specific (special) requirements that the port direct current of this reader antenna is opened a way, and has universality.
These data that are operated in the electronic tag 37 of test pattern that reader 39 reads can be simple identity informations, can be the data messages that comprises antenna performance also, pass to the computer 310 that reader 39 connects.The antenna that has the electronic tag 37 of data message, for reader 39, the information of electronic tag 37 information that the reader main frame is read by comparison and reader self storage or is connected the information that the computer 310 of reader stores can realize asset identification and the performance inventory of reader system to its reader antenna.
For the unauthorized antenna of reader, promptly there is not electronic tag or the electronic tag data that has does not meet the authority of reader, reader can not send data.The information of the information of this function electronic tag 37 that to be the reader main frame read by comparison and reader 39 self storage or is connected the information that the computer 310 of reader 39 stores and judges.
In a word, the ultrahigh frequency electronic tag that will be in test pattern is fixed between radome and the ground plate, and reader is read the data of this electronic tag, has realized multi-functional intelligent reader antenna.
The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
