一种节省有源IC卡电量的方法及系统
摘要：
本发明涉及IC卡领域，提供一种节省有源IC卡电量的方法及系统。有源IC卡生产完成后，设定IC卡在休眠状态下接收唤醒信号的第一间隔时间和IC卡在工作状态下接收休眠信号的第二间隔时间。S1：使IC卡进入或保持休眠状态；S2：第一间隔时间过后，判断IC卡是否接收到唤醒信号，若否，则返回步骤S1；若是，则执行步骤S3；S3：判断接收到的唤醒信号是否正确，若否，则返回步骤S1；若是，则执行步骤S4；S4：使IC卡进入或保持工作状态；S5：第二间隔时间过后，判断IC卡是否接收到休眠信号，若否，则返回步骤S4；若是，则执行步骤S6；S6：判断接收到的休眠信号是否正确，若否，则返回步骤S4；若是，则返回步骤S1。该方法及系统能有效节约IC卡内部电源的损耗。
摘要（英）：

The invention relates to the field of IC cards and provides a method and a system for saving electric quantity of an active IC card. After the active IC card is produced, first interval time for receiving a wake-up signal by the IC card in a sleep state and second interval time for receiving a sleep signal by the IC card in a working state are set. The method comprises the steps of S1: enabling the IC card to enter or keep the sleep state; S2: after the first interval time, judging whether the IC card receives the wake-up signal or not, and if not, returning to the step S1, or if yes, performing the step S3; S3: judging whether the received wake-up signal is correct or not, and if not, returning to the step S1, or if yes, performing the step S4; S4: enabling the IC card to enter or keep the working state; S5: after the second interval time, judging whether the IC card receives the sleep signal or not, and if not, returning to the step S4, or if yes, performing the step S6; and S6: judging whether the received sleep signal is correct or not, and if not, returning to the step S4, or if yes, returning to the step S1. The method and the system can effectively reduce the loss of power in the IC card.
