Abstract

The utility model discloses a ground identifier, which is connected with a reader-writer and is communicated with a backstage computer by the reader-writer via wireless or wire type. The ground identifier comprises at least two antennas and a containing chamber for containing the antennas, wherein the antennas can transmit the data of cards or electronic tags read by the reader-writer to the backstage computer to be judged and identified when there is card or electronic tag identified. The utility model has the advantages that the ground identifier overcomes the problem that the prior art needs to regulate personnel entrance mode, the arrangement of cards and electronic tags or the card holding type, which can quickly identify cards and electronic tags. The ground application of the ground identifier can avoid the effect of distance, human body interference or obstacles.

Description

Paste ground formula recognizer

Technical field

The utility model relates to a kind of ultrahigh frequency RFID (Radio FrequencyIdentification, be called for short radio-frequency (RF) identification) equipment, particularly relates to a kind of device that personnel's carry-on ID card card or electronic tag are carried out quick accessible identification.

Background technology

At present, pass in and out management devices,, all need to satisfy in the condition one or multinomial no matter which frequency range what be to use is the personnel of known use RFID:

1, require one of personnel and then one pass through the device zone, promptly personnel can not pass through simultaneously;

2, to solve card and must be close to the antenna of device and swipe the card, promptly can not discern at a distance;

3, verification card hold or modes of emplacement has multiple requirement, can only be such as solving card by clip in the front, perhaps label can only be installed in the bongrace of cap etc., promptly can not at will be placed in each pocket on one's body.

Because, if the RFID of high and low frequency card card and electronic tag read the too near or identification frequency of identification distance and hang down and just can only discern one by one, if distance then when RFID card card that reads the identification ultrahigh frequency and electronic tag, the people knows from experience the very big interference effect of identification generation, therefore, if do not satisfy above-mentioned condition, the situation that certain personnel of skip pass in and out card card and electronic tag then will certainly appear.

The utility model content

In view of the above problems, fundamental purpose of the present utility model is to provide a kind of subsides ground formula recognizer of avoiding very easily occurring skip card card and electronic tag situation when personnel pass in and out management devices.

In order to achieve the above object, the utility model has adopted following technical proposals:

Described subsides ground formula recognizer is the ccontaining cavity that comprises at least two antennas and be used for ccontaining this described antenna, and this subsides ground formula recognizer both can be installed on the ground, also also can be arranged at underground and with the ground shape that maintains an equal level, wherein, described antenna will be for judging veritification from the data transmission that card blocks or electronic tag reads in background computer when recognizing card card or electronic tag and by read write line.

By subsides described in the utility model ground formula recognizer, can overcome under the prior art pattern and must pass in and out pattern or demonstrate,prove the problem that card, the modes of emplacement of electronic tag and the mode of holding are stipulated personnel, just can discern fast and detect, and can not be subjected to the influence that distance is far and near, human body disturbs or stops, and personnel can accessiblely pass through when entering surveyed area, in actual applications, has practical value.

Description of drawings

Fig. 1 is the structural representation that pastes ground formula recognizer described in the utility model;

Fig. 2 is the ground formula recognizer one concrete enforcement connection layout of using that pastes described in the utility model.

Embodiment

Come subsides described in the utility model ground formula recognizer is described in further detail below in conjunction with accompanying drawing and concrete enforcement.

The relative prior art of subsides described in the utility model ground formula recognizer can be when the personnel of stipulating demonstrate,prove card and electronic tag modes of emplacement, and personnel's carry-on card card and electronic tag read identification fast.

Shown in Fig. 1, the ccontaining cavity 10 that subsides described in the utility model ground formula recognizer 1 comprises at least two antennas 11 and is used for ccontaining this described antenna 11, and this described subsides ground formula recognizer 1 both can be installed on the ground, also also can be arranged in underground, promptly, this described ccontaining cavity 10 that pastes ground formula recognizer 1 can be made as blanket type, and described antenna 11 is placed in one; Or as the belt of slowing down on the highway, and described antenna 11 is placed in one; Dig also or on ground and to establish a pit, should described subsides ground formula recognizer 1 be placed in one and maintain an equal level with ground.

In the application, shown in Fig. 2, described antenna 11 be for will judging veritification from the data transmission that card blocks or electronic tag 2 reads in background computer 4 when recognizing card card or electronic tag 2 and by read write line 3, and this described antenna 11 can to select Alientechnology company be the FTD-A9050LUHF model that rfid interrogator 3 designs.

Shown in Fig. 1 and Fig. 2, owing to be installed on the device of personnel's above-head for the personnel that the use RFID many antennas 11 that will discern usefulness when passing in and out management devices under the prior art pattern, perhaps be installed on the device that is positioned at the personnel both sides, therefore, interfering with each other of human body very easily appears when a plurality of personnel pass in and out, perhaps owing to stopping mutually between personnel's health, perhaps because antenna distance card card is far away, outside 2 meters and cause a little less than the signal, thereby cause the thing of skip to take place.

Subsides described in the utility model ground formula recognizer 1 is for adopting the ground formula of pasting, being about to antenna 11 places below personnel's step, no matter personnel will demonstrate,prove card or electronic tag 2 is positioned over pocket or trouser pocket, card card or electronic tag 2 can not surpass 2 meters all the time with the distance of antenna 11, and can not blocked between antenna 11 and card card or electronic tag 2 by personnel's oneself health; Also no matter whether card card or electronic tag 2 are that relative position is placed between personnel, the situation that can not cause signal to be blocked takes place; And since this kind paste ground formula recognizer 1 personnel by the time be positioned at all the time below personnel's step, also can be owing to the problem that the human body interference takes place of distance.

In the practical application, 2 antennas are selected in setting of pasting antenna 11 in the ground formula recognizer 1 described in the utility model selectivity as required, perhaps 4 antennas, perhaps other even number aerial array formula is arranged, and this described antenna 11 transmits radiofrequency signal at card card, electronic tag and 3 of read write lines.

In addition, this described subsides ground formula recognizer 1 is both applicable in the management of personnel's license visa card, and same also can be applied on article, goods, animal and the management of vehicles.

Claims

1. one kind is pasted ground formula recognizer, and it is connected in read write line, is characterised in that, this recognizer comprises at least two antennas and in order to the ccontaining cavity of ccontaining described antenna.

2. according to the described subsides of claim 1 ground formula recognizer, it is characterized in that it is for being installed on the ground.

3. according to the described subsides of claim 1 ground formula recognizer, it is characterized in that it is for being arranged in underground and simultaneously being to maintain an equal level with ground surface.
