The present invention provides a kind of multi-function active electronic tag, application system and method thereof. The system includes a control processor, a coordinator, an active electronic tag, used for receiving instruction signals during the time of listening state, and a reader/writer, wherein the active electronic tag includes: a soft-filtering module, used for judging whether the address code of the signals, received by the active electronic tag through the first channel, is right or not; and a hard-filtering module, used for filtering the signals on the hardware side to remove invalid signals before performing the soft-filtering on the signals. The present invention enables the low power consumption of the active electronic tag, the bidirectional communication working as required, and the long distance transmission of information, thereby the standard communication process of the active electronic tag is optimized and the useful life of the tag is extended. Furthermore, a kind of active electronic tag with the actions of multiple fixed modes, application system and method thereof are provided, thus the communication efficiency of the wireless communication system is improved, and the probability of signal collision and mutual interference is effectively reduced. |
