4. The refuge guide system (100) of claim 1, wherein the central communication unit (104) is configured to perform wired communication with the refuge guide device (20) through a power line network.

5. The refuge guide system (100) of claim 1, further comprising an auxiliary positioning unit (260), the auxiliary positioning unit (260) comprising:

a gyroscope (262) providing an azimuth angle information of the refuge guide device (20); and

a gravity sensor (264) sensing a speed and an acceleration of the refuge guide device (20);

wherein the auxiliary positioning unit (260) is configured to provide the azimuth angle information, the speed and the acceleration to the control unit (200).

6. The refuge guide system (100) of claim 1, wherein the central server (10) is configured to periodically transmit the guide information to the wireless communication unit (220) of the refuge guide device (20), and the wireless communication unit (220) is configured to transmit the guide information to the control unit (200), for storing the guide information in a memory element (202) of the control unit (200).

7. The refuge guide system (100) of claim 1, wherein the central server (10) is configured to transmit the guide information to the wireless communication unit (220) of the refuge guide device according to a certain condition, and the wireless communication unit (220) is configured to transmit the guide information to the control unit (200), for storing the guide information in a memory element (202) of the control unit (200).

8. The refuge guide system (100) of claim 1, wherein the wired communication unit (250) of the refuge guide device (20) is configured to receive the guide information, and is configured to transmit the guide information to the control unit (200), for storing the guide information in a memory element (202) of the control unit (200).

9. A refuge guide method arranged for a refuge guide device (20), the refuge guide method comprising the following steps:

transmitting a guide information to the refuge guide device (20) by a central server (10);
