Specific embodiment

Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other It can be combined with each other.

As shown in Figure 1, the utility model provides a kind of remote read-write card device, including single-chip microcontroller, the single-chip microcontroller connection There are power circuit, wireless transport module and read-write card circuit, chip microcontroller remotely controlled by wireless transport module, Read-write card is written and read by single-chip microcontroller.

As shown in Fig. 2, in the present embodiment, single-chip microcontroller uses the single-chip microcontroller of model STM32F103C, the single-chip microcontroller function It consumes low, small in size.

The power circuit of single-chip microcontroller includes battery, as shown in figure 4, battery passes through booster circuit for the voltage liter of 3.2V To 5V be single-chip microcontroller and and whole device circuit power supply, booster circuit includes PS3120A chip, PS3120A chip it is defeated Enter end to connect with lithium battery, the output end of PS3120A chip is connect with single-chip microcontroller；As shown in figure 3, the charging circuit of battery by Chip TP4056 realizes that the gelled SOP8 encapsulation of bottom belt and less outer member number, TP4056 become just The ideal chose of formula application is taken, TP4056 can be suitble to USB power source and adaptor power supplies to work.

As shown in figure 5, wireless transport module uses SIM800C chip, it is city that SIM800C, which is four frequency GSM/GPRS modules, The encapsulation of fort hole, performance are stablized, and appearance is small and exquisite, and cost performance is high, are able to satisfy a variety of demands of client, SIM800C working frequency is GSM/GPRS850/900/1800/1900MHz can realize the transmission of voice, SMS and data information with low-power consumption, due to SIM800C is having a size of 17.6*15.7*2.3mm, so capableing of the volume of the entire card reader device of diminution largely.
