Abstract:
1. An electronic tag time-sharing control method, comprising the steps of: providing a plurality of wireless electronic tags; executing a time-sharing control procedure by a server within a default display information update cycle to transmit a plurality of time-sharing control signals to the wireless electronic tags respectively for setting a default wakeup timing of each wireless electronic tag and a corresponding sleep cycle thereof; resuming each wireless electronic tag from a sleep status to a standby status according to the set default wakeup timing, and transmitting an acknowledge signal to the server; determining whether the transmission time of each acknowledge signal is matched with the default wakeup timing of each wireless electronic tag; transmitting a display message to each wireless electronic tag by the server to update the display information of each wireless electronic tag, when the transmission time of each acknowledge signal is matched with the default wakeup timing of each wireless electronic tag; returning the acknowledge signal including an update confirmation message after the display information of each wireless electronic tag is updated; and transmitting a time-sharing control signal to each wireless electronic tag again to enter each wireless electronic tag into the sleep cycle again after the server receives the acknowledge signal including the update confirmation message, and setting each wireless electronic tag to a default wakeup timing of the next wakeup time wherein the server device delays the display information update time of the wireless electronic tag and rearranges the updated priority order of the wireless electronic tag display information to the last position, when the server determines that the transmission time of each acknowledge signal is not matched with the default wakeup timing.
