Abstract

The invention relates to a method for identifying electronic information, more particularly a method for identifying animal identity. The method of the invention sequentially comprises the steps of: using a hand-held reader for writing the relevant information of animals into an electronic label in the manner of low frequency close distance, close field electromagnetic coupling; attaching the electronic label to the animals; operating the hand-held reader to send high frequency reading signal to read the information of the electronic label within an effective range into the reader. The method of the invention has the advantages that the hand-held reader can induct in a long distance in the working mode of non-contact at high frequency range and can simultaneously read dozens of electronic labels; the induction distance at low frequency range is quite close, which guarantees the one to one data write-in efficiently and includes higher security and interference immunity.

Description

Based on the animals recognition method of radio frequency technique high and low frequency in conjunction with application

Technical field

The present invention relates to a kind of electronic information recognition methods, especially a kind of animal identification recognition methods.

Background technology

Because the continuous generation that the extensive continuation outburst of the various eqpidemic diseases of animal and dog class breeding process are slandered people's incident, the standardized management of animal and the problem of breed are paid attention to by people day by day, radio RF recognition technology is as a new technology, but have characteristics such as the only numbering non-contact inductive in the electronic tag whole world, can be used as an effective means and go to manage animal.

Animal identification recognition methods in actual at present the use has two kinds: methods such as livestock immunity ear board and dog class implanted electronic tag are used in respectively in the immunity management and the management of dog class of animal.

Livestock immunity ear board method is to the mark of being worn a small amount of identity information of record by the management animal.The shortcoming of livestock immunity ear board method has: be difficult to correctly to distinguish whether this animal wears legal ear board and then can not correctly discern the immune legitimacy of this animal under by the situation of dirt under staff's distance objective animal situation far away or at the ear board, if target animal is the dog class, then cause the mistake of law enforcement behavior easily; If target animal is the dog class, then the staff is not easy to list and dog legitimacy only near target close-ups dog para-immunity; But livestock immunity ear board data carried by data amount is very limited, and the shortcoming of this kind form is for very easily falling mark.

The implanted electronic label method is that the electronic tag of a grain of rice size is implanted in the dog body, and electronic tag carries out contactless communication by low frequency radio frequency technology and recognizer.The shortcoming of this method is: the low-frequency electronic label is invisible to the naked eye after being implanted in the dog body, can not with the naked eye distinguish dog legitimacy only; The low-frequency electronic tag read distance is nearer relatively, and recognizer must read near electronic tag.And because the free property of animal muscle tissue, the low-frequency electronic label position after the implantation is difficult to be judged; Recognizer once can only read the information of a low-frequency electronic label, is not suitable for dog and only assembles use under the occasion.

Summary of the invention

The purpose of this invention is to provide a kind of tens electronic tags that can be used for reading simultaneously, have higher security and anti-interference based on radio frequency technique high and low frequency in conjunction with the animals recognition method of using.

For realizing purpose of the present invention, it is a kind of based on the animals recognition method of radio frequency technique high and low frequency in conjunction with application that this instructions provides, its method step comprises successively, with handheld reader the relevant information of animal, adopt low frequency closely, the mode of near field electromagnetic coupling is written to electronic tag inside; Electronic tag is worn on one's body the animal; The operation handheld reader sends high frequency read signal, and the electronic labeling information in the effective range is read into reader successively.

Handheld reader comprises the method step that low frequency signal writes electronic tag, the user is provided with on handheld reader and treats write information, send write command and give handheld reader, the MCU of handheld reader promptly sends to the RFID module controller to information to be written by interface after receiving order, controller is arranged to connect with the low frequency module of low frequency module and electronic tag again, data are write electronic tag, and electronic tag confirms by the low frequency return message whether writing information is correct.

Handheld reader comprises by the method step that high-frequency signal reads electronic labeling information, the user operates the handheld reader button and sends reading order, the reader RFID module HFS that says the word, HFS outwards sends request signal, in effective range and satisfactory electronic tag can be activated, the HFS of electronic tag receives request signal, and the information in the label returned send to reader, the electronic tag that legal animal is worn after reading can send alert messages such as acousto-optic, and arrangement for reading can search all the legal animals in the effective range.

The low-and high-frequency that the present invention proposes a kind of wireless radio-frequency (Radio Frequency Identification Technology, be called for short RFID) is combined in the application on the care of animal.Use high frequency (comprising more than the 300MHz the following frequency range of 5.8GHz) to read information, low frequency (comprising more than the 100KHz the following frequency range of 150KHz) writing information.High frequency can adopt the 2.45GHz frequency range, reads electronic labeling information, and 2.45G belongs to international frequency range, meets international applications standard and national agricultural industry application standard, also can adopt 433MHz, 915MHz etc.Low frequency can adopt the 134.2KHz frequency range, writes electronic labeling information, and 134.2KHz belongs to the international standard frequency range that RFID animal husbandry is used, and also can adopt 125KHz, 128KHz etc.The advantage of high band is that distance of reaction is far away, can reach tens of rice, and the anti-technology maturation of colliding can be used for reading simultaneously tens electronic tags, adopts non-contacting working method; The distance of reaction of low-frequency range is nearer, can guarantee effectively that man-to-man data write, and has higher security and anti-interference.

The present invention adopts outward appearance to adopt visual sign, makes the staff adopt wireless radio-frequency identification can carry out the legitimacy of naked eyes discrimination objective animal before in advance; In the dog class is used, adopt the identification application identities of listing to substitute the application identities of the mode of implanting, eliminated the infliction of body that original technology is brought animals such as dog classes; The mode that adopts high frequency to read substitutes the mode that low frequency reads, and has improved the recognizer service range, and can read the information of a plurality of signs simultaneously; The present invention can increase storage space flexibly, overcomes the restriction of original technology storage data capacity.

Purpose of the present invention, feature and advantage will be in conjunction with the embodiments, are further described with reference to accompanying drawing.
