Abstract

The application discloses non -contact IC card in wrist can be worn to modified annular, including integrated circuit card body and annular carrier, the integrated circuit card body is inlayed on annular carrier, and the integrated circuit card body comprises two screening glass and card base, antenna and the chip of clamp in the middle of two screening glass, carves on the annular carrier and the equal groove of integrated circuit card body size. The circuit structure of chip is simple, has reduced the cost of manufacture, adopts MCU, EEPROM and concrete logic circuit, and it is convenient to realize, has solved and has adopted current ordinary circuit to lead to the preparation complicated easily, the not high technical problem of sensitivity.

Description

A kind of annular of improvement can be worn on the non-contact IC card in wrist

Technical field

The annular that the utility model relates to a kind of improvement can be worn on the non-contact IC card in wrist.

Background technology

Publication number is patent document discloses a kind of annular and can being worn on non-contact IC card in wrist of CN202145320U; comprise integrated circuit card body and annular carrier; integrated circuit card body is embedded on annular carrier; integrated circuit card body is made up of two panels screening glass and card base, antenna and the chip be clipped in the middle of two panels screening glass, and annular carrier carves the groove equal with integrated circuit card body size.Described annular can be worn on the non-contact IC card in wrist, only needs integrated circuit card body to inlay to be clipped on annular carrier, and technique is simple, easy to make; Described annular carrier can custom materials and size according to demand, arbitrarily wears, attractive in appearance flexibly.But the remarkable shortcoming of this technical scheme is: the specific implementation structure not disclosing chip, and, adopt existing common realizing circuit easily to cause making complexity, the technical matters that sensitivity is not high.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, there is provided a kind of annular of improvement can be worn on non-contact IC card in wrist, it which discloses the optimum feasible program of chip, solves and adopts existing common realizing circuit easily to cause making complexity, the technical matters that sensitivity is not high.

To achieve these goals, the technical solution adopted in the utility model is: a kind of annular of improvement can be worn on the non-contact IC card in wrist, comprise integrated circuit card body and annular carrier, integrated circuit card body is embedded on annular carrier, integrated circuit card body is by two panels screening glass and be clipped in the middle card base of two panels screening glass, antenna and chip are formed, annular carrier carves the groove equal with integrated circuit card body size, it is characterized in that: described chip comprises MCU, described MCU connects an eeprom memory, the P0.3 port of described MCU connects U21, U21 is connected with photodiode U12, U12 is contact resistance R19 again, also comprise not gate U22, it connects electric capacity C11 and resistance R11, R11 connects potentiometer R13, R13 connects a d type flip flop U11, also comprise and door U23, its contact resistance R14, the base stage of R14 connecting triode Q10 again, the emitter of Q10 connects electric capacity C14 and resistance R15.

The beneficial effects of the utility model are:

Chip comprises MCU, and described MCU connects an eeprom memory, and circuit structure is simple, reduce cost of manufacture, adopt MCU, EEPROM and concrete logical circuit, it is convenient to realize, and solves and adopts existing common realizing circuit easily to cause making complexity, the technical matters that sensitivity is not high.

Accompanying drawing explanation

Accompanying drawing described herein is used to provide further understanding of the present application, and form a application's part, the schematic description and description of the application, for explaining the application, does not form the improper restriction to the application.In the accompanying drawings:

Fig. 1 is that the annular that the utility model improves can be worn on the circuit diagram of the chip of the non-contact IC card in wrist.

Embodiment

Below in conjunction with specific embodiment, such scheme is described further.Should be understood that these embodiments are not limited to for illustration of the utility model limit scope of the present utility model.The implementation condition adopted in embodiment can do further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in normal experiment.

The annular that the utility model provides a kind of improvement can be worn on the non-contact IC card in wrist, comprise integrated circuit card body and annular carrier, integrated circuit card body is embedded on annular carrier, integrated circuit card body is by two panels screening glass and be clipped in the middle card base of two panels screening glass, antenna and chip are formed, annular carrier carves the groove equal with integrated circuit card body size, as shown in Figure 1, described chip comprises MCU, described MCU connects an eeprom memory, the P0.3 port of described MCU connects U21, U21 is connected with photodiode U12, U12 is contact resistance R19 again, also comprise not gate U22, it connects electric capacity C11 and resistance R11, R11 connects potentiometer R13, R13 connects a d type flip flop U11, also comprise and door U23, its contact resistance R14, the base stage of R14 connecting triode Q10 again, the emitter of Q10 connects electric capacity C14 and resistance R15.

Preferably, not gate U22 adopts the CD40106 with Si Mite function, itself and resistance R11, R13 and electric capacity C11 form oscillator, U11 adopts d type flip flop, U21 adopts 74HC04, after carrying out two divided-frequency by d type flip flop 4013, obtain the audible frequency of square-wave signal as hummer, this frequency changes by regulator potentiometer R13.74HC04 and MCU connects, and cost of manufacture reduces about 20%, and when use has abnormal, setting software program, after judging identification by MCU, output alarm signal, carries out onsite alarming prompting.

Preferably, on card base, lay antenna, afterwards chip pasted on card base, by the method for welding, by chip and sky wire bonding good, be clipped in the middle with two panels screening glass, blend compounds is firmly bonding, forms a complete integrated circuit card body.

Preferably, on annular carrier, output a sulculus, with containing integrated circuit card body.The shape of this groove can be the various shapes such as rectangle, circle, ellipse, and the shape mainly depending on integrated circuit card body makes.

preferably, in the sulculus of the annular carrier made, put into integrated circuit card body, and spreading glue between them, like this, annular carrier and integrated circuit card body and shaping.
