The eSIM card concept is to embed a conventional SIM card directly onto a low power consumption location device chip rather than being a separate removable component that is added to the low power consumption location device, without the user having to insert a physical SIM card. Because a separate SIM card slot is not needed to be arranged for the low-power-consumption positioning device, the low-power-consumption positioning device adopting the eSIM design has lighter and thinner volume. The low-power-consumption positioning device adopts the eSIM module, a communication operator can be selected independently, and the internal space of the low-power-consumption positioning device occupied by the traditional SIM card module is also reduced. This application adopts magnetism to inhale formula charging mode, has guaranteed charge efficiency, the security of charging, has also ensured low-power consumption positioner's seal. The selection of the eSIM module and the magnetic type charging module ensures the tightness of the low-power-consumption positioning device, and the overall waterproof grade of the low-power-consumption positioning device reaches IPX8.

And 2, after the gravity sensor is influenced by the environment to generate a change value, transmitting the change value to the awakening receiver, and judging whether the awakening signal is filtered by an awakening controller of the awakening receiver.
3, if the wake-up signal needs to be filtered, the wake-up signal is masked. According to the time interval, multiple awakening signals within M minutes from the last awakening command response are shielded, continuous energy consumption work of the low-power-consumption positioning device is avoided, and long endurance is ensured.
4, if the wake-up signal does not need to be filtered, the wake-up signal is immediately transmitted to the host, and the host wakes up to start working. The positioning module searches satellite signals to perform positioning, the eSIM communication module searches base station signals to perform networking communication, and the system self-check completes self-check.
And 5, the host can select a working mode in a working state, a new working mode takes effect immediately after the working mode is selected, and an M value for controlling a time interval of a filtration awakening signal of the low-power-consumption positioning device and a count X value for dormancy can also be set.
And 6, the host transmits data according to the integrity of the positioning information and the self-checking information, records the X time for successfully transmitting the information, and after the X time, the host is actively powered off to enter a sleep mode.
7, repeating the above process.
