For example, the jamming detection module 231 detects a jamming attack when the frequency band of mobile communication is rapidly changed to a state in which communication is impossible within a predetermined time range in an area within the same range, for example, within a radius of several kilometers. can judge

The jamming detection module 231 may provide the slave response module 232 or location information transmission module 234 with a determination as to whether there is a jamming attack.

For example, in a jamming attack situation, the slave response module 232 may transmit a jamming situation message to the slave device 300 .

As another example, in a jamming attack situation, the location information confirmation module 233 interworks with GPS satellites to generate vehicle location information, and the location information transmission module 234 uses the second wireless communication module 242 to create a wireless mesh network. The location information of the vehicle can be provided to the service server using .

The slave response module 232 may perform direct communication with the slave device 300 . For example, the slave response module 232 may receive a status check message from the slave device 300 and, if in a normal state, provide a status response message to the slave device 300 . When the slave device 300 does not receive the status response message, it may determine that the master device 100 is in an abnormal state.

The battery unit 320 may provide power to other components of the slave device 300 using power stored in the battery. Depending on the embodiment, the battery unit 320 may change and provide a voltage or current suitable for other components.

The wireless communication unit 340 may support at least one wireless communication method. In the illustrated example, the wireless communication unit 340 will be described as an example supporting a wireless mesh network, but is not limited thereto.

The controller 330 may operate the slave device 300 by controlling other components of the slave device 300 .

If the status response message for the status confirmation message is not received within a predetermined time, the control unit 330 activates the location confirmation unit 310 to generate vehicle location information, and via the wireless communication unit 340, the controller 330 generates information about the location of the vehicle to other vehicles. It may be controlled to provide vehicle location information to a service server using a wireless mesh network formed in conjunction with other vehicle location tracking devices attached thereto.

If a status response message is received from the master device 200 within a preset time, the controller 330 may control the slave device 300 to be set in a sleep mode for a predetermined time.

For example, the controller 330 may set the wireless communication unit 340 to operate even in the sleep mode. When receiving a jamming situation message from the master device 200 through the wireless communication unit 340 in the sleep mode, the controller 330 switches the slave device 300 to a wake-up state and activates the positioning unit 310. to generate vehicle location information, and through the wireless communication unit 340, control to provide the vehicle location information to the service server using a wireless mesh network formed in conjunction with another vehicle location tracking device attached to another vehicle. can

For example, the mode management module 331 sets to operate in the sleep mode for a certain period of time, operates a wake-up timer during the operation in the sleep mode, wakes up the slave device 300 after a certain period of time, and sets the operation mode can be converted to

As another example, the mode management module 331 may wake up the slave device 300 when a jamming message is received through the wireless communication unit 340 .

Alternatively, the mode management module 331 may switch to the sleep mode after the slave device 300 wakes up and switches to the operation mode, generates vehicle location information and transmits the location information to the service server. This is to efficiently use storage power of the battery since the slave device 300 operates based on the battery.

The emergency state determination module 332 may determine an emergency state of the master device 200 .

For example, the emergency state determination module 332 may control to transmit a status confirmation message to the master device 200 in an operating state, and if the master device 200 does not receive a status response message for it, an emergency status can be set.

As another example, when a jamming message is received through the wireless communication unit 340, the emergency state determination module 332 may set an emergency state.

When the emergency state determination module 332 determines an emergency state, it may inform the location information confirmation module 333 and the location information transmission module 334 of this. The location information confirmation module 333 obtains the location information of the vehicle in conjunction with the GPS satellite and provides it to the location information transmission module 334, and the location information transmission module 334 transmits the location information of the vehicle to the wireless communication unit 240. Through this, it can be controlled to provide to the service server.
