Active electronic tags as well as system and method applying active electronic tags

The invention provides active electronic tags with a plurality of fixed pattern actions as well as a system and method applying the active electronic tags in order to reduce the time of air communications of the active electronic tags so as to alleviate the condition of signal congestion. The system comprises a control processor, a coordinator, the active electronic tags and a reader, wherein theactive electronic tags are used for receiving command signals in the time period (namely the moment of monitoring the signals after waking from periodic sleep) of monitoring the states. The inventionhas the following beneficial effects: the programs carrying out fixed pattern operations are pre-stored in the active electronic tags and then the wake-up commands with the greatly reduced are transmitted to the active electronic tags to call and carry out the programs, thus reducing the time of air communications of the active electronic tags, improving the communication efficiency of the radio communication system, relie
