Abstract

A method capable of providing a low power geofence service according to the present invention comprises the steps of: detecting a reference Vrect value for estimating an indoor/outdoor position from a solar charger of a position tracker; determining whether the solar charging module (solar charger) of the position tracker is in a charging or non-charging situation, on the basis of the detected Vrect value; if it is determined that the solar charging module of the position tracker is in the charging situation, determining that the position of the position tracker is outdoors and acquiring position tracking data by using a global positioning system (GPS) module; if it is determined that the solar charger of the position tracker is in the non-charging situation, determining that the position of the position tracker is indoors or in a shaded area, and acquiring position tracking data by using one among Bluetooth low energy (BLEs), wireless fidelity (Wi-Fi), and ultra-wide band (UWB) modules other than the GPS module; and transmitting the acquired position tracking data to a server by using a low power communication scheme.

Claims7

Dependent claims

A device of location tracking for providing low power consuming geo-fence service, comprising:

a body member;
a first bend member and a second bend member;
a flexible battery having a predetermined length, inserted into a receiving portion of the first and second band members, and disposed so that the remaining length except for the portion inserted in the receiving portion is located inside the body member;
a solar charging module for producing self-power;
and
a circuit board including at least one of a Wireless Fidelity (WIFI), a Bluetooth Low Energy (BLE), a Global Positioning System (GPS), a real-time communication, a Ultra Wide Band (UWB), a Low Power Wide Area Network (LPWAN) communication module for obtaining a location tracking data and communication with network and a control unit (MCU) for controlling the location tracking device;
wherein the control unit changes the communication module to minimize power consumption of the flexible battery according to a detected operation of solar charging module,
wherein the control unit determines that the location of the location tracking device is outdoor and the location tracking data is obtained using the GPS module when the solar charging module is a charging operation, and
wherein the control unit determines that the location of the location tracking device is indoor and the location tracking data is obtained by one of the BLE, the WIFI, and the UWB module other than the GPS module when the solar charging module is a non-charging operation.

6 more elements

A method of location tracking for providing low power consuming geo-fence service in a location tracking device, comprising:

detecting a Voltage drop of the rectifiers (Vrect) value which is a reference value for determining a charging or a non-charging operation of the solar charging module;
determining whether the solar charging module is charging operation or non-charging operation based on the detected the Vrect value;
determining that a location of the location tracking device is outdoor and a location tracking data is obtained using a Global Positioning System (GPS) module when the solar charging module is in the charging operation;
determining that a location of the location tracking device is indoor and a location tracking data is obtained using one of a Bluetooth Low Energy (BLE), a Wireless Fidelity (WIFI) Sniffing, and an Ultra-Wide Band (UWB) modules other than the GPS module when the solar charging module is in the non-charging operation;
and
transmitting the location tracking data through a Low Power Wide Area Network (LPWAN) communication module,
wherein the location tracking data is obtained using the GPS module further comprising:
determining whether the location tracking data obtained using the GPS module is stably obtained, and if the location tracking data is not stably obtained using the GPS module, and determining the location of the location tracking device is indoor and obtaining the location tracking data using one of the BLE, the WIFI, and the UWB module, and
wherein the location tracking data is obtained using one of the BLE, the WIFI, and the UWB module other than the GPS module, further comprising:
determining whether location tracking data is stably obtained using the location tracking module used before determining the location of the location tracking device is indoor according to the solar charging module,
searching other location tracking module which is most stably obtainable the location tracking data when the location tracking data is not stably obtained using the used location tracking module, and
obtaining the location tracking data by the searched location tracking module.
