Abstract: This application discloses a power consumption control method and system for an electronic positioning device, and an electronic positioning device. The method includes: obtaining sensing data of a sensor for sensing a physical quantity of an object's state of motion (101); determining, based on the sensing data, whether a current condition meets a preset trigger condition, to obtain a first determining result (102); sending a first control instruction when the first determining result indicates that the current condition meets the preset trigger condition (103), where the first control instruction is used to enable a positioning module in the electronic positioning device such that the positioning module is in an on state; and maintaining the positioning module in an off state when the first determining result indicates that the current condition does not meet the preset trigger condition (104).
