<p>Provided is a vehicle monitoring system capable of easily identifying information transmitted from respective detection devices without requiring registration of identifiers of the detection devices. A detection device (10, 10A) transmits vehicle information including a detection result and its identifier. A tractor relay device (30) and a trailer relay device (20) includes its identifier in vehicle data (80, 80A) received according to the identifier of the detection device (10, 10A), transmits the vehicle data (80, 80A), and transmits registration data (60) containing its relay device ID (63) and a type (62) indicating registration of the relay device ID (63). The tractor relay device (30) stores the relay device ID (63) of the registration data (60) transmitted from the trailer relay device (20) according to the type information, transmits the registration data (60), and transmits the vehicle data (80, 80A) received from the trailer relay device (20) according to the relay device ID (63). A display device (40) receives the registration data (60) and the vehicle data (80, 80A) transmitted from the tractor relay device (30) and stores the relay device ID (63) of the registration data (60) according to the type information.</p> |
