Abstract
The present invention discloses an electronic tag time sharing control system and a method thereof, and the system comprises a server, at least one coordinator and a plurality of wireless electronic tags. The server transmits a time-sharing control signal. The coordinator and the server form a wireless connection for receiving and transmitting the time-sharing control signal. The wireless electronic tags and the coordinators form a wireless connection. After each wireless electronic tag receives the time-sharing control signal, different sleep cycle and wakeup timing are generated to update display information sequentially. A portion of the wireless electronic tag is situated at a sleep status and a portion of the wireless electronic tag is situated at a standby status to receive the update display information, so as to achieve the effects of saving bandwidth, reducing packet collisions and extending the service life of the wireless electronic tag.
