Embodiment Construction
[0015] Under normal circumstances, 6 is in state a, the lithium battery automatically charges the capacitive energy storage unit with a small current and in a stable manner, and the capacitive energy storage unit provides electric energy for the active electronic tag working circuit in a micro-current discharge;
[0016] After the counter counts to a certain cycle time T1, trigger 2 to enter state b;
[0017] The time length of state b is T2, and the task of sending the ID identification information of the tag is completed within the T2 period. The capacitive energy storage unit provides electric energy to the active electronic tag working circuit in a large current discharge, and the time period of the large current discharge is T2. At this time, the lithium battery is still automatically charged to the capacitive energy storage unit with a small current and in a stable manner, and after T2 ends, 6 returns to state a;
[0018] Re-enter the next round of working state cycle.
