Abstract
The utility model relates to a test card used for defining a card reading range of a radio frequency identification (RFID) card reader, which comprises an RFID unit, and is characterized by also comprising a control unit, a counting unit and a display device. Through displaying the time of the RFID card reader sending mutual information to the test card on the test card, implementation personnel can simply and visually judge the effective induction zone range of the card reader, thereby, the construction efficiency of arranging a long-distance RFID system is improved.
Description
Technical field
The utility model relates to the RFID technical field, is specifically related to adopt a kind of test card that is used to define RFID card reader Card Reader scope.
Background technology
REID (RFID, i.e. Radio Frequency Identification) is to utilize RF-wise to carry out contactless bidirectional communication data exchange to reach the technology of automatic identification.Make up radio-frequency recognition system and should comprise following two parts, the one, RFID card reader, the 2nd, radio-frequency card at least.Compare with traditional magnetic card, IC-card; The radio-frequency card biggest advantage just is noncontact, therefore need not manual intervention when accomplishing identification work, be suitable for the robotization of the system that realizes and not fragile; High-speed moving object can be discerned and a plurality of radio-frequency cards can be discerned simultaneously, swift and convenient to operate.Radio-frequency card is not afraid of rugged environments such as oil stain, contamination by dust, short-range radio-frequency card can be under such environment alternative bar code, be used in the occasion tracked object such as streamline of factory.The product of long distance is used in the traffic more, and distance can reach tens meters, can be used on occasions such as automatic charge or identification identity.At present, REID is widely used in various fields such as logistics management, traffic management and control, anti-counterfeiting information, entrance guard management.
The inventor finds in actual application:
When disposing the long-range radio-frequency recognition system; Very big (its location parameter is as shown in Figure 1, comprising: the distance L of the level height H of RFID card reader, RFID card reader and radio-frequency card, the RFID card reader is axial and angle, the axial anglec of rotation β of RFID card reader of horizontal direction because the position that the RFID card reader is disposed is to effective range (actual induction district) influence of induction received RF card.), and the enforcement personnel can't intuitive judgment RFID card reader induction range, often need adjust RFID card reader location parameter repeatedly, and to define optimum induction range, this has had a strong impact on disposes the operating efficiency when the long-range radio-frequency recognition system is installed.
To this situation, the solution that adopts at present is: the emissive power through RFID card reader detection radio-frequency card, be sent to debug terminal, and debug terminal identifies the emissive power that radio frequency is stuck in diverse location, judges the induction region scope to reach.But because the emissive power of RFID card reader induction radio-frequency card is non-linear; The power influence value of radio-frequency card itself is less; Only if adopt the higher circuit design of cost significantly to improve the detection sensitivity of card reader, otherwise be difficult to distinguish the variation of power influence value, judge the induction region scope.
Therefore, how card reader actual induction scope is defined in simple and practical completion, is the technical matters that industry needs to be resolved hurrily thereby improve the operating efficiency of disposing when the long-range radio-frequency recognition system is installed.
Summary of the invention
The purpose of the utility model is through a kind of test card that is used to define RFID card reader Card Reader scope being provided, addressing the above problem.
For achieving the above object, the utility model adopts following technical scheme:
A kind of test card that is used to define RFID card reader Card Reader scope comprises that the RFID rfid uint is characterized in that also comprising control module, counting unit, display device; Said control module, RFID rfid uint, counting unit are connected with display device successively;
Further, said control module comprises the test button, and said display device comprises light emitting diode or LCDs.
Its principle of work is following:
When the RFID card reader was sensed test card, based on the REID principle, the RFID card reader was sent interactive information to test card, and the number of times of interactive information received in the counting unit record of test card, and showed through display device.When the distance between test card and the RFID card reader was increased to a certain degree, because the power influence value diminishes, the number of times that causes the RFID card reader to sense test card tailed off, and the number of times that the while test card can receive RFID card reader transmission interactive information also can tail off.Therefore, through the numerical values recited that shows on the test card, just can judge the induction of test card position; Through just defining the actual induction scope of RFID card reader behind the multi-point sampler basically.
The utility model sends the interactive information number of times through on test card, showing the RFID card reader to test card; Can simple and direct let the technician judge card reader actual induction district scope, thereby improve the operating efficiency of disposing when the long-range radio-frequency recognition system is installed.
Description of drawings
Fig. 1 is a RFID card reader actual induction district synoptic diagram;
Fig. 2 is the fundamental diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model content is described further.
Embodiment
As shown in Figure 2, the operational testing card in preset RFID card reader actual induction district is pressed the test button, and control module control RFID rfid uint is worked in second at setting-up time t and (for the ease of describing, supposed t=10 second, n=60 in this instance n time.), when the RFID card reader was sensed test card, based on the REID principle, the RFID card reader was sent interactive information to test card, and the number of times m (m≤n), and show through display device of interactive information received in the counting unit of test card record.
Further, when display device was LCDs, test card received that the number of times of interactive information directly is shown as numerical value; When display device is light emitting diode, utilize diode " bright/as to go out " corresponding scale-of-two " 1/0 ", through a plurality of diodes test card is received that the number of times of interactive information shows with binary mode.
Test card is moved to different positions test respectively, when the RFID card reader was sensed the number of times m=n of test card, the distance between judgement test card and the RFID card reader was in actual induction district scope; When the RFID card reader is sensed the number of times 0＜m of test card＜n, judge distance between test card and the RFID card reader in the actual induction district bounds; When the RFID card reader is sensed the number of times m=0 of test card, judge that the distance between test card and the RFID card reader exceeds actual induction district bounds.
In practical application, value in 0＜m＜n usually, as the boundary value in actual induction district, in the present embodiment, definition m=30 is the boundary value in actual induction district, then decidable is card reader actual induction district in this scope of 30＜m≤60.
Obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
