Embodiment
Embodiment 1
A kind of rfid interrogator as shown in Figure 1 and the integrated machine of video camera, it comprises UHF RFID antenna (101), ultrahigh frequency RFID read-write cell (102), camera (103), graphics processing unit (104), common bus (105), processor (106), reservoir (107), communication interface (108) and communication link (109);
Wherein, UHF RFID antenna (101) is connected with ultrahigh frequency RFID read-write cell (102), camera (103) is connected with graphics processing unit (104), communication interface (108) is connected with communication link (109), communicates in a wired or wireless fashion with other equipment;
Wherein, ultrahigh frequency RFID read-write cell (102), graphics processing unit (104), processor (106), reservoir (107) are all connected with common bus (107) with communication interface (108).
Embodiment 2
Rfid interrogator shown in Fig. 2 and the application of the integrated machine of video camera in traffic monitoring.On read-write and the camera shooting integrated machine 100 special portal frame 201 that is arranged on traffic intersection or electric pole, adjust the orientation angles of its RFID antenna 101 and camera 103, make it just in time can the automobile 202 that is in crossroad of perception and shooting.Ultra-high-frequency passive RFID label tag 203 installed by each current automobile 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 the implementing procedure figure of the integrated machine of video camera in traffic monitoring.After receiving the instruction of traffic console, read-write and camera shooting integrated machine 100 start to start 301, enter holding state 302 subsequently.At holding state 302, all-in-one can perform inquiry instruction 303 always, asks whether traffic lights are in red light phase: if not, then keep holding state 302, if red light phase, then perform instruction 304, open RFID read-write unit.After RFID read-write unit is opened, perform inquiry instruction 305, ask that whether having perceived automobile passes through at traffic intersection: if do not perceive, then get back to holding state 302; If perceived automobile to pass through, then perform instruction 306, opened camera shutter and capture, and perform the instruction 307 candid photograph result being transferred to traffic console.Each candid photograph completes and after result is transferred to traffic console, all-in-one all can perform instruction 308, and whether inquiry has the order of shutdown: if not, then get back to holding state 302; If there is 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, and do not need to know license plate number 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, based on the method for image recognition, can only detect about 50% vehicle made a dash across the red light.And ultrahigh frequency RFID electronic license plate recognition system, when the speed of a motor vehicle of speed per hour 50 kilometers or more, electronic license plate signal more than 120 times can be read continuously, the possibility failed to report can not be had in theory.Therefore, 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, and can also reach the accuracy rate of almost 100%, rate of failing to report is close to zero.
All-in-one of the present invention can also be recorded in the information of vehicles running red light in internal storage location 107, so that inquiry and statistics.
All-in-one of the present invention can also be written to the information of making a dash across the red light in the RFID label tag of automobile; Such all-in-one just can read the gross information content that traffic violated by automobile.When traffic console obtains violating regulation number of times more automobile information, real-time command can be sent to traffic-police, interception inspection is carried out to this car.
Embodiment 3
All-in-one of the present invention can also be used in multiple goal of a mass character, long-time shooting or video recording occasion.Perform in the embodiment of occasion extensive utility man, each utility man has worn ultrahigh frequency RFID electronic tag.All-in-one is uninterruptedly taken a picture to stardom or is recorded a video.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 record a video in frame.Like this, from the picture library of magnanimity, just can find photo or the video recording frame of any one utility man accurately and rapidly.This feature can also be used for the inquiry of clue afterwards of security monitoring occasion.Such as, from being stored into various places, the magnanimity photo library of each period and video library, any one all photos knowing the suspect object of its electronic tag identity and frame of video can be rapidly retrieved to.And this work, under current technical conditions, almost can not complete.
All-in-one of the present invention can also be used for the real-time security monitoring occasion at mass-meeting scene.Such as, can need to carry in the extensive mass-meeting of personal identification label (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 by the image unit of all-in-one, emphasis carried out to it and monitor in real time.All-in-one also can screen out the personnel not carrying identity label, and carries out key monitoring to it.
