Abstract
The utility model provides a non-contact recognition system of animal individuals by using surface acoustic wave, which consists of a surface acoustic wave label, an upper computer and a reader, wherein the surface acoustic wave label is fixed on each livestock body; the upper computer and the reader are arranged on a management center; the surface acoustic wave label comprises a sensor antenna, a transducer, a substrate and a coding reflecting area; and the reader comprises a controller, a signal transmitting circuit, a transfer switch, a reader antenna and an echo receiving circuit. The signal transmitting circuit controlled by the controller transmits a high-frequency pulse signal, and the signal is received by the sensor antenna of the surface acoustic wave label arranged on livestock subjected to quarantine and converted into surface acoustic wave by the transducer; the surface acoustic wave forms echo after encountering reflecting bars of the coding reflecting area; the echo is converted into electromagnetic wave by the transducer; and the electromagnetic wave is transmitted back to the reader by the sensor antenna and then transmitted to the controller through the echo receiving circuit, thus a code of each livestock can be recognized and transmitted to the upper computer. The code of each livestock acquired by the system and a quarantine result acquired by an animal quarantine place can be simultaneously transmitted to the management center and used for building archives for the livestock.
Description
Technical field
The utility model relates to a kind of target contactless identification system, especially adopts the contactless identification system of surface acoustic wave techniques identification animal individual.
Background technology
The demand that becomes more meticulous along with aquaculture production, need follow the tracks of growing of every animal, promptly livestock is consumed link from be born to entering and carry out whole process supervision, and its various relevant informations are carried out record, set up individual archives, for example prevent epidemic and health check-up processing etc. for livestock, this just need utilize the individual identification technology.At present, the large-scale plant of tradition relies on technology such as infrared and bar code to management and the individual identification of livestock, this technology is discerned the livestock numbering need carry out closely manual operations, and this closely manual method, have the following disadvantages: at first be that workload is very big, such as: stained all can the causing of label can't be discerned, and discern needs to clean label; Secondly, appearance along with some new virus, because livestock has been infected some disease and may pass through the worry that the contact keeper propagates to society, at present some plants have adopted remote prevent epidemic the new measure with the health check-up processing of livestock that is, this discerns livestock at a distance with regard to needs, could guarantee to prevent epidemic individual corresponding with livestock with the result of health check-up processing for livestock.The wireless radiofrequency label is the unique technical that replaces present widely used bar code, but its service range is general only in 1 meter, obviously can not satisfy the requirement of at a distance livestock being discerned.
Summary of the invention
The purpose of this utility model is to provide a kind of animal individual contactless identification system, makes it can realize at a distance the individuality of animals such as livestock being discerned.
The purpose of this utility model is achieved in that native system is made up of the host computer 14 and the reader that are fixed on the surface acoustic wave label on each livestock health and be installed in administrative center, described surface acoustic wave label comprises sensor antenna 1, transducer 2, base material 3 and coding echo area 4, wherein, described coding echo area 4 is made up of some reflection bars of arranging by coding principle; Sensor antenna 1, transducer 2 and coding echo area 4 are installed on the base material 3; Described reader comprises controller 5, signal transmission circuit, switch 9, reader antenna 10, echo receiving circuit, wherein, described signal transmission circuit comprises high-frequency signal generation circuit 6, launch site circuit of high pass filter 7, the launch site shaping circuit 8 that connects successively, and described echo receiving circuit comprises reception area circuit of high pass filter 11, reception area shaping circuit 12, the signal amplifier circuit 13 that connects successively; An output terminal of controller 5 is connected with host computer, another output terminal is connected with the input end of switch 9 and signal transmission circuit, the output terminal of signal transmission circuit is connected with the input contact of switch 9, is connected with reader antenna 10 behind switch 9; The output contact of switch 9 is connected with the input end of echo receiving circuit, and the output terminal of echo receiving circuit 9 is connected with the input end of controller 5.
The purpose of this utility model further can realize like this: transducer 2 preferred interdigital transducers.
The using method and the principle of native system are: the controller 5 control transformation switches 9 of reader are in emission state, high-frequency signal generation circuit 6 in the signal transmission circuit produces high-frequency signal, this signal is after 7 filtering of launch site circuit of high pass filter, 8 shapings of launch site shaping circuit, and it sends electromagnetic pulse signal by reader antenna 10 to the livestock of preventing epidemic or health check-up is handled by controller 5 control.After this signal was launched, controller 5 control transformation switches 9 were in accepting state.After this signal is received by sensor antenna 1, be converted into surface acoustic wave by transducer 2, run into the coding echo area 4 reflection bar after form echo, echo is converted into electromagnetic wave again by transducer 2 and launches by sensor antenna 1 once more, these echoed signals have formed by the number of the reflection bar of substrate surface and the pulse train of determining positions, it is similar to bar code pattern, and the time delay of each pulse depends on acoustic surface wave propagation speed.Reader is after reader antenna 10 receives the echo-pulse string, output contact through switch 9 is connected with the input end of echo receiving circuit, after the filtering of echo receiving circuit, shaping, amplification, decode at controller 5, the preventing epidemic coding of the livestock of handling with health check-up, this coding slave controller 5 is passed host computer back.Writing down the relevant information of every livestock on the host computer, simultaneously, the computing machine that the epidemic prevention processing of this livestock that obtains with the health check-up place from preventing epidemic and the result of health check-up are provided with by the health check-up place through network to host computer 14 transmission of administrative center, be pooled to the host computer 14 of administrative center, and with stored information contrast, discern and record.
The beneficial effects of the utility model are: owing to after adopting the native system device, can carry out individual identification to animals such as livestocks exactly at a distance, guaranteed the result that livestock is prevented epidemic with health check-up is handled is conformed to the livestock individuality.
