Abrégé
The present invention relates to a wireless communication relay system. An unmanned device used in a wireless communication relay system comprises: a surrounding environment information acquiring unit for acquiring information on a surrounding environment of a moving object; a processing unit for generating a control command for the moving object by using the acquired information on the surrounding environment; and a communication unit for transmitting the control command generated by the processing unit to the moving object, wherein the unmanned device is located at a predetermined height or higher and relays communication between the moving object and a control center, and thus, even when wireless communication between the control center and the moving object is difficult due to an obstacle or the like, the connection of the wireless communication may be maintained without disconnection of the wireless communication.
