Description of drawings
Below in conjunction with accompanying drawing,, will make technical scheme of the present invention and other beneficial effects apparent by the specific embodiment of the present invention is described in detail.
In the accompanying drawing,
Fig. 1 is traditional single read head rfid system syndeton synoptic diagram;
Fig. 2 is the syndeton synoptic diagram of rfid system one preferred embodiment of the present invention.
Embodiment
Figure 2 shows that the syndeton synoptic diagram of rfid system one preferred embodiment of the present invention.Wherein, the read head 3 of this system communicates to connect switch/merit sub-module 41 respectively according to its signalling channel, switch/merit sub-module 42...... switch/merit sub-module 4N, in physics realization, this module can be a switch module, it also can be a power division module, each switch/merit sub-module is connected with its corresponding antenna communication respectively, switch/merit sub-module 41 corresponding antenna the 11......1X that connect, switch/merit sub-module 42 corresponding antenna the 21......2Y that connect, ... the corresponding antenna N1......NZ that connects of switch/merit sub-module 4N, the guarded region of the corresponding electronic tag of each antenna, corresponding monitored space 1X0 of the corresponding monitored space 110...... antenna 1X of antenna 11 just, the corresponding monitored space 2Y0 of antenna 21 corresponding monitored space 210...... antenna 2Y, the corresponding monitored space NZ0 of the corresponding monitored space N10...... of antenna N1 antenna NZ; The signal of each passage of described read head 3 is assigned to several through its pairing switch/merit sub-module, the several read head signal that each switch/merit sub-module is told outputs to its pairing some antennas again respectively, renders to the guarded region of each antenna correspondence.Thereby, utilize this system, on the basis that does not increase the read head number, increased number of antennas greatly, make a read head 3 can connect switch/merit sub-module 41, switch/merit sub-module 42...... switch/N switch/merit sub-modules such as merit sub-module 4N, and then connection antenna 11... antenna 1X, antenna 21...... antenna 2Y, ..., X+Y+......+Z antennas such as antenna N1...... antenna NZ, and then this X+Y+......+Z antenna again can a corresponding X+Y+......+Z monitored space, thereby has enlarged the monitoring area of rfid system.In this preferred embodiment, the read head chip type that the quantity N of switch/merit sub-module, antenna amount X, the Y......Z etc. of read head 3 each signalling channel correspondence all can be according to actual needs, adopted, switch/merit sub-module type, antenna type etc. are chosen according to qualifications.In this preferred embodiment, read head 3 also can connect access device 5, and this access device 5 can comprise the network equipment or computing machine etc., thus the expanded function of providing.
If the electronic tag that reads in aerial position with by this antenna is corresponding one by one, just realization that can be natural is to the location of each electronic tag.In the existing rfid system as shown in Figure 1, because read head can be controlled each antenna separately, realize that therefore the location is comparatively simple, but when using the configuration of Fig. 2, the location becomes very complicated, and simple processing can not be matched electronic tag and the antenna of reading electronic tag.When a read head carries a plurality of antenna work, how to realize the separation of each antenna data, in other words, how to match antenna and be the key that realizes the location by the electronic tag that this antenna reads in.
The locator meams that this preferred embodiment can realize has three kinds: one, when read head or computing machine when which antenna gauge tap/merit sub-module output to signal flexibly, and antenna and can realize the nature pairing by the electronic tag that this antenna is read.The location of realizing with this kind mode, the signal transmission that needs the additionally additional control signal wire of system to come gauge tap/merit sub-module, for example, by controlling a switch module, having or not of this switch module respective antenna signal of may command, the electronic tag of being read when antenna and its have signal can be realized the nature pairing.Two, we do unique number can for each antenna, putting up the corresponding localized electron label of numbering therewith near the antenna or on the antenna, in the time of near the antenna work this localized electron label, localized electron label as sign is discerned by read head, this moment, the antenna of other label that is read into natures and the unique correspondence of this localized electron label was tied to together, had realized the location.Three, we do unique number can for the antenna under the same read head signalling channel, antenna under the unlike signal passage is not then done requirement, putting up the corresponding localized electron label of numbering therewith near the antenna or on the antenna, in the time of near the antenna work this localized electron label, localized electron label as sign is discerned by read head, in conjunction with this localized electron label pairing read head signalling channel this moment, specific antenna under other labels that are read into natures and this read head signalling channel is tied to together at this moment, has realized the location.In these three kinds of modes, two, three is similar, do not need the additionally additional control line of system, only need preestablish the localized electron label and get final product, and realizes that locator meams is simple, cost is lower, and the user can choose locator meams arbitrarily according to actual needs in this three.
The above; for the person of ordinary skill of the art; can make other various corresponding changes and distortion according to technical scheme of the present invention and technical conceive, and all these changes and distortion all should belong to the protection domain of accompanying Claim of the present invention.
