Detailed description of the invention
Embodiment 1
A kind of rfid interrogator as shown in Figure 1 and the integrated machine of video camera, it includes UHF RFID antenna (101), ultrahigh frequency RFID read-write cell (102), photographic head (103), graphics processing unit (104), common bus (105), processor (106), bin (107), communication interface (108) and communication link (109)；
Wherein, UHF RFID antenna (101) is connected with ultrahigh frequency RFID read-write cell (102), photographic head (103) is connected with graphics processing unit (104), communication interface (108) is connected with communication link (109), communicates with other equipment in a wired or wireless fashion；
Wherein, ultrahigh frequency RFID read-write cell (102), graphics processing unit (104), processor (106), bin (107) are all connected with common bus (107) with communication interface (108).
Embodiment 2
Rfid interrogator shown in Fig. 2 and the application in traffic monitoring of the video camera integrated machine.Read-write and camera shooting integrated machine 100 are arranged on special portal frame 201 or the electric pole of traffic intersection, adjust its RFID antenna 101 and the orientation angles of photographic head 103 so that it is the automobile 202 just can being in crossroad with perception and shooting.Each current automobile is mounted with ultra-high-frequency passive RFID label tag 203 in front window.Read and write and be connected with traffic console 205 by netting twine 204 with camera shooting integrated machine 100.
Rfid interrogator as shown in Figure 3 and video camera integrated machine implementing procedure figure in traffic monitoring.After receiving the instruction of traffic console, read-write and camera shooting integrated machine 100 start to start 301, subsequently enter holding state 302.At holding state 302, all-in-one can perform to inquire instruction 303 always, asks whether traffic light are in red light phase: if it is not, then keep holding state 302, if red light phase, then performs instruction 304, opens RFID read-write unit.After RFID read-write unit is opened, performing inquiry instruction 305, asking that whether having perceived automobile passes through at traffic intersection: if being not detected by, then return to holding state 302；If having perceived automobile to pass through, then perform instruction 306, open camera shutter and capture, and perform candid photograph result to be transferred to the instruction 307 of traffic console.After having captured and result is transferred to traffic console every time, all-in-one all can perform to instruct 308, asks whether the order of shutdown: if it is not, then return to holding state 302；If there being off-mode, then perform END instruction 309.
Due to when the automobile made a dash across the red light captured by all-in-one, the electronic license plate number of this automobile has been obtained by RFID read-write unit, therefore, the automobile information made a dash across the red light can be collected by traffic console in real time, know license plate number without by the method for artificial cognition capture pictures, or utilize the way of complicated intelligent image identification software to know license plate number.Car plate diagnostic method according to manual method or complicated intelligent image identification software can not be accomplished real-time, and error rate is hated.Because these reasons, tradition method based on image recognition, it is only able to detect about 50% vehicle made a dash across the red light.And ultrahigh frequency RFID electronic license plate identification system, electronic license plate signal can be read more than 120 times continuously when speed per hour 50 kilometers or above speed, can not have the possibility failed to report in theory.Therefore, the RFID read-write of the present invention and camera shooting integrated machine not only can the vehicles that make a dash across the red light of real-time perception, moreover it is possible to reaching the accuracy rate of almost 100%, rate of failing to report is close to zero.
The all-in-one of the present invention can also be the information record of vehicles running red light in internal storage location, in order to inquires about and adds up.
The all-in-one of the present invention can also be written to the information made a dash across the red light in the RFID label tag of automobile；So all-in-one just can be read automobile and violate the gross information content of traffic.When traffic console obtains violating regulation number of times more automobile information, real-time command can be sent to traffic-police, carry out this car intercepting and check.
Embodiment 3
The all-in-one of the present invention can be also used in multiple target of a mass character, long-time shooting or video recording occasion.In extensive utility man performs the embodiment of occasion, each utility man has worn ultrahigh frequency RFID electronic tag.Stardom is uninterruptedly taken a picture or records a video by all-in-one.In the process, the RFID read-write unit of all-in-one is in non-stop run state, the electronic label code all the time perceived can be synthesized in the photo of this moment shooting or in video recording frame.In this manner it is possible to find photo or the video recording frame of any one utility man from the picture library of magnanimity accurately and rapidly.This feature can be also used for the inquiry of clue afterwards of security monitoring occasion.Such as, all photos and the frame of video of any one suspect object knowing its electronic tag identity can be rapidly retrieved to from storage to various places, the magnanimity photo library of each period and video library.And this work, under the conditions of current technology, it is practically impossible to.
The all-in-one of the present invention can be also used for the real-time security monitoring occasion that mass-meeting is on-the-spot.Such as, can be in the extensive mass-meeting needing to carry personal identification label (such as second generation identity card), suspicious record personnel participating in the meeting can be filtered out in real time, rapidly from the RFID read-write unit of all-in-one, and the image unit passing through all-in-one has carried out emphasis to it and monitored in real time.All-in-one can also screen out the personnel not carrying identity label, and it is carried out key monitoring.
