Abstract
The invention provides a method for controlling data transmission in a 2.4GHz active radio frequency identification (RFID) tag. The method comprises the steps that: a 900MHz passive tag reader cyclically transmits control data according to a preset instruction; a 900MHz passive tag module receives the control data and transmits an interrupt signal to a micro control unit (MCU); the MCU reads the control data after being waken; and the MCU controls a 2.4GHz radio frequency module to perform corresponding data transmission according to the contents of the control data or enters a sleep state. According to the method, the data transmission of the 2.4GHz active RFID tag can be intelligently controlled; and moreover, the 2.4GHz active RFID tag is low in power consumption and long in service life.
