Low-power-consumption mixed structure positioning method and device based on bisynchronization

The invention provides a low-power-consumption mixed structure positioning method and device based on bisynchronization. The method comprises the following steps: a UWB base station periodically sends a communication request frame to a UWB label through a 2.4 G transceiver, and after the communication request frame is sent, the 2.4 G transceiver at a base station end is started at an interval of 150 us for 150 us and is closed. When the pre-opening time t01 of the scanning window of the base station is reached, the UWB base station opens the 2.4 G transceiver of the base station end again for 64ms and then closes the 2.4 G transceiver again; searching an idle time slot from the current positioning time slots, calculating the starting time of the idle time slot, and replying a synchronous response frame to the UWB tag; after the start time of each non-idle time slot arrives, the base station end UWB transceiver is turned on, and the base station end UWB transceiver is automatically turned off if the time is ou
