Abstract
The invention provides a radio frequency intelligent card which is characterized by comprising an acceleration sensor, a radio frequency module and an intelligent card module. The acceleration sensor is in signal connection with the intelligent card module. The acceleration sensor can output an IO interrupt signal to the intelligent card module. The intelligent card module controls the radio frequency module through a GPIO/SPI interface. The invention also provides an energy control method of the radio frequency intelligent card. According to the radio frequency intelligent card and the energy control method, working of the radio frequency module does not need extra trigger equipment, under normal conditions, the radio frequency module is in a closed state, power consumption is extremely low, using the radio frequency intelligent card by a user is very convenient, and only shaking the radio frequency intelligent card before use is enough.
Description
Technical field
The present invention relates to a kind of radio frequency smart card that radio-frequency module, acceleration transducer and conventional smart card is integrated, and the energy control method of this radio frequency smart card.
Background technology
In the prior art, the control of the energy consumption of radio frequency smart card, a kind of method is that second method is through the electromagnetic induction device through the work of smart card module timing wake-up radio-frequency module, like the magnetic induction device, or coil.
Shortcoming is:
Method one: the method power consumption consumption rate is bigger;
Method two: the method must increase extra flip flop equipment when activating radio-frequency module.
Summary of the invention
In view of this, be necessary that the present invention provides a kind of novel smart card and smart card energy control method that reduces the consumption of radio-frequency module and need not extra increase flip flop equipment to the problem of mentioning in the background technology.
The objective of the invention is to realize through following technical scheme:
A kind of radio frequency smart card; It comprises an acceleration transducer, a radio-frequency module and a smart card module; Said acceleration transducer is connected with said smart card module signal; The exportable IO look-at-me of said acceleration transducer to said smart card module, said smart card module is controlled said radio-frequency module through the GPIO/SPI interface.
Said acceleration transducer comprises a signal output module, and it is used for receiving when vibrating at the intelligent card body, and output IO look-at-me is to said smart card module.
Said smart card module comprises a vibration induction module, a control module and a turnover sleep module;
Said vibration induction module is used to respond to the vibration from the intelligent card external;
Said control module is used for when said vibration induction module is not sensed the vibration from the intelligent card external; Through GPIO/SPI interface control radio-frequency module, make it get into sleep pattern, and; When said vibration induction module is sensed the vibration from the intelligent card external; Through GPIO/SPI interface control radio-frequency module, control said radio-frequency module and withdraw from sleep pattern, and carry out radio frequency operation;
Said turnover sleep module is used for not sensing the vibration from the intelligent card external when said vibration induction module; And said control module is through GPIO/SPI interface control radio-frequency module; It is got into after the sleep pattern, control said smart card module self and get into sleep pattern; And, after said vibration induction module is sensed the vibration from the intelligent card external, control said smart card module self and release sleep pattern.
A kind of radio frequency smart card energy control method, it may further comprise the steps:
The first step: when said acceleration transducer was not exported the IO look-at-me, said smart card module made it get into sleep pattern through GPIO/SPI interface control radio-frequency module, and then, smart card module self gets into sleep pattern;
Second step: when the intelligent card body receives when vibrating; Acceleration transducer output IO look-at-me is to said smart card module; This look-at-me arousing intelligent card module withdraws from sleep pattern; Said smart card module is controlled said radio-frequency module through the GPIO/SPI interface and is withdrawed from sleep pattern, and carries out radio frequency operation;
The 3rd step: smart card module changes the first step over to after said radio-frequency module is operated.
With old compared with techniques, the invention has the advantages that:
1, do not need extra flip flop equipment to make radio-frequency module work;
2, under normal conditions, radio-frequency module is in closed condition, and power consumption is extremely low;
3, the user is very easy to use, gets rid of before using to get final product.
