Abstract

The utility model relates to an electronic device, in particular to an electronic information card reader. The shell of the double frequency reader is in the composite structure of an upper shell and a lower shell. The upper shell and the lower shell are connected by means of embedment. A display screen window, an infrared window, indicator lights and keystrokes are arranged on the upper shell. A battery cover is arranged on the lower shell. Antennae and a circuit motherboard are arranged between the upper shell and the lower shell. The antennae and the motherboard are electrically connected. The antennae comprises a low-frequency antenna and a high-frequency antenna. Both of the low-frequency antenna and the high-frequency antenna are electrically connected with the mother board. The utility model has the advantages that high frequency is combined with low frequency; by adopting high-frequency band, cards can be remotely sensed and some dozens of electronic labels can be read at the same time; the sensing distance of low-frequency band is short, and data can be ensured to be written in effectively in a one-to-one manner; the electronic information card reader is very safe and can resist interference well.

Description

A kind of double frequency reader

Technical field

The utility model relates to a kind of electronic equipment, especially a kind of electronic information reader device.

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 immune 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 135KHz radio-frequency technique 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 utility model is the problem that exists at background technology, and a kind of double frequency reader of low-and high-frequency combination is provided.

For realizing the purpose of this utility model, this instructions provides a kind of double frequency reader, and its shell adopts unitized construction up and down, and upper casing is connected by the setting-in mode with lower casing, be provided with display screen windows, infrared window, pilot lamp, button on upper casing, lower casing is provided with battery cover; Be provided with antenna and circuit board mainboard between the last lower casing, antenna and mainboard are realized being electrically connected.

Antenna comprises low-frequency antenna and high frequency antenna, and both all are electrically connected with mainboard.

The circuit board mainboard comprises radio frequency identification module and data collection processor module, and both are electrically connected by wiring board.

Comprise in the radio frequency identification module and comprise transmission in the radio frequency identification module and receive control module, low frequency modulations and demodulation module, high frequency modulated and demodulation module; Send and receive control module one end connection low-frequency antenna and high frequency antenna, other end connection low frequency modulations and demodulation module and high frequency modulated and demodulation module; Low frequency modulations and demodulation module and high frequency modulated and demodulation module all are connected on the data processing module.

The utility model has solved original technical disadvantages, has proposed a kind of wireless radio-frequency Radio FrequencyIdentification Technology, and the low-and high-frequency of abbreviation RFID is combined in the application on the care of animal.Use high frequency (comprising that more than the 300MHz, 5.8GHz is frequency range once) to read information, low frequency (comprising that more than the 100KHz, 150KHz is frequency range once) 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 equifrequent.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 equifrequent.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, efficiently solves the shortcoming of original technology.

The utility model comprises shell and reader circuitry plate main body, circuit board section comprises the PDA module, the RFID module, four parts such as keyboard and supplying cell, the PDA module specifically comprises demonstration, the LED indication, storer and master controller, the RFID module comprises low frequency module and high-frequency model, the user sends instruction by button to the PDA module, the PDA module is made a response according to different orders, if data query, just access data from storer, on display screen, show then, if read command, the HFS of the RFID module that just says the word, read the master controller that returns to the PDA module after the data, show then, when reader sends reading order, the characteristics of high frequency have been used, have remote, the characteristics that many labels read, if write order, send order and data low frequency part to the RFID module, send to the target electronic label, obtain return messages then, when reader sends the writing information order to electronic tag, the characteristics of low frequency have been used, adopt the mode of electromagnetic coupled, send energy earlier to electronic tag from reader, low frequency communication has short-range communication simultaneously, security is protected, and the information that reader is sent is guaranteed only to be written in the target electronic label; Supply module is powered to RFID module and PDA module.
