[embodiment]
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
In addition, if below in described each embodiment of the present invention involved technical characteristic do not form conflict each other and just can mutually combine.
Embodiment 1
As shown in Figure 1, for the embodiment of the present invention 1 one kinds saves the method flow diagram of active IC-card electricity, after active IC-card has been produced, setting IC-card receives the first interval time of wake-up signal and IC-card lower the second interval time receiving sleep signal in working order in the dormant state, comprises the following steps:
S1: IC-card is entered or keeps dormant state;
Active IC-card after production is completed, the project that can not drop into timely for various reasons uses, if make IC-card in running order, then inner battery can produce insignificant electric energy loss, therefore need setting IC-card receive the first interval time of wake-up signal in the dormant state and make IC-card enter dormant state, this first interval time can need setting arbitrarily according to user self.Such as, the first interval time was set as 1 hour, after IC-card enters dormant state by us, did not now receive or sent any radiofrequency signal, and at interval of 1 hour, IC-card can receive a radiofrequency signal.
After the S2: the first interval time, judge whether IC-card receives wake-up signal, if not, then return step S1; If so, then step S3 is performed;
S3: judge that whether the wake-up signal received is correct, if not, then return step S1; If so, then step S4 is performed;
S4: IC-card is entered or keeps duty;
After the first interval time of setting, IC-card can receive the radiofrequency signal that the external world sends, if now IC-card does not receive wake-up signal, then continues to keep dormant state; If now IC-card receives wake-up signal, then need to judge that whether wake-up signal is correct.In order to ensure the security that data are transmitted and accuracy, usually data check code is added in data transmission procedure, namely the signal sent comprises data division and data check code, data division refers to the data that will send, and data check code is the numeric data code utilizing data to calculate according to certain data check algorithm.After whether the wake-up signal that judgement receives correctly is specially and receives wake-up signal, extract data division, according to the data check algorithm same with sending data, calculate data check code, verify that whether it is consistent with the data check code of sent wake-up signal, if not, then IC-card is made to keep dormant state; If so, IC-card is then made to enter duty.
After the S5: the second interval time, judge whether IC-card receives sleep signal, if not, then return step S4; If so, then step S6 is performed;
S6: judge that whether the sleep signal received is correct, if not, then return step S4; If so, then step S1 is returned.
In the use procedure of active IC-card, active IC-card is after completing interim work, when lying idle for a long time, inner battery also can produce insignificant electric energy loss, therefore receive the second interval time of sleep signal under needing setting IC-card in working order, this second interval time can need to set arbitrarily according to user self.Such as, the second interval time was set as 1 hour, after IC-card enters duty by us, now can only send radiofrequency signal, can not received RF signal, at interval of 1 hour, IC-card can receive a radiofrequency signal, if now IC-card does not receive sleep signal, then continues to keep duty; If now IC-card receives sleep signal, then need to judge that whether sleep signal is correct.After whether the sleep signal that judgement receives correctly is specially and receives sleep signal, extract data division, according to the data check algorithm same with sending data, calculate data check code, verify that whether it is consistent with the data check code of sent sleep signal, if so, then make IC-card keep duty, if not, then IC-card is made to reenter dormant state.
The invention provides a kind of method of saving active IC-card electricity, the first interval time of wake-up signal and IC-card lower the second interval time receiving sleep signal is in working order received in the dormant state by setting IC-card, make IC-card be in dormant state before not receiving wake-up signal always, duty can be entered after receiving wake-up signal, it can be made again again to enter dormant state after completing interim work, user constantly can switch the using state of IC-card as required, the method effectively can save the loss of IC-card internal electric source, increase the term of life of active IC-card.
Embodiment 2
As shown in Figure 2, for the embodiment of the present invention 2 one kinds saves the system construction drawing of active IC-card electricity.Comprise:
Time setting module 10, receives the first interval time of wake-up signal and IC-card lower the second interval time receiving sleep signal in working order in the dormant state for setting IC-card;
Status control module 20, enters for making IC-card or keeps dormant state, enters or keeps duty;
Signal judge module 30, for judging whether IC-card receives wake-up signal, if not, then makes IC-card keep dormant state by status control module 20; If so, then judge that whether the wake-up signal received is correct, if not, then make IC-card keep dormant state by status control module 20, if so, then make IC-card enter duty by status control module 20; For judging whether IC-card receives sleep signal, if not, then IC-card is made to keep duty by status control module 20; If so, then judge that whether the sleep signal received is correct, if not, then make IC-card keep duty by status control module 20, if so, then make IC-card enter dormant state by status control module 20.
Below in conjunction with specific embodiment, a kind of system use procedure of saving active IC-card electricity is conducted further description: after active IC-card has been produced, utilize time setting module 10 to set IC-card and receive the first interval time of wake-up signal and IC-card lower the second interval time receiving sleep signal in working order in the dormant state, status control module 20 makes IC-card enter dormant state, and now IC-card can not receive or send any radiofrequency signal.After the first interval time, signal judge module 30 judges whether IC-card receives wake-up signal, and if not, status control module 20 makes IC-card keep dormant state; If so, signal judge module 30 judges that whether the wake-up signal received is correct, and whether it is consistent with the data check code of sent wake-up signal to be specially checking, if not, status control module 20 makes IC-card keep dormant state, and if so, status control module 20 makes IC-card enter duty.
After entering duty, every the first interval time, signal judge module 30 judges whether IC-card receives sleep signal, and if not, status control module 20 makes IC-card keep duty; If, whether the sleep signal that signal judge module 30 receives is correct, whether it is consistent with the data check code of sent sleep signal to be specially checking, if not, then status control module 20 makes IC-card keep duty, if so, then status control module 20 makes IC-card reenter dormant state.
The invention provides a kind of system of saving active IC-card electricity, comprise time setting module 10, status control module 20 and signal judge module 30.Set IC-card by time setting module 10 and receive the first interval time of wake-up signal and IC-card lower the second interval time receiving sleep signal in working order in the dormant state, utilization state control module 20 realizes active IC-card and switches back and forth in working order and between dormant state, active IC-card is made to keep dormant state for a long time when the project that do not drop into uses or places and do not use, internal electric source loss is down to minimum, extends the serviceable life of active IC-card.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
