Abstract

The invention relates to a control method of a lockup clutch state collecting circuit. When the radio frequency identification (RFID) electronic tag of the collecting circuit integrating the lockup clutch state or the RFID device of the collecting circuit adopting the lockup clutch state is in a RFID field, the control method comprises the step (a) and other steps, wherein the step (a) is that the RFID electronic tag or the RFID device enters the RFID field, the radio frequency analog front-end of the RFID electronic tag is electrified to work. The beneficial effects of the invention are as follows: the lockup clutch state collecting circuit of the invention has the advantages of low power consumption and interference resistance; and as the lockup clutch state collecting circuit can be integrated in the electronic tag, the collecting circuit is easier to combine with the electronic tag to be used as the monitoring node of the Internet of things for moving containers and proof boxes in the logistics industry, thus timely monitoring the lockup clutch state of containers and proof boxes and ensuring the safety of moving containers and proof boxes.
