1. A method comprising:
detecting a first state of a transmit path of a relay device in a transmit period through a radio frequency coaxial cable;
sending, through the radio frequency coaxial cable and when the transmit path is in an abnormal state, a fault diagnosis trigger signal to the relay device to enable the relay device to enter a fault diagnosis mode, wherein the fault diagnosis trigger signal comprises one or more of a variable supply voltage value, a transmit/receive control signal, or a diagnosis control signal;
detecting a second state of the relay device in the fault diagnosis mode through the radio frequency coaxial cable; and
determining a fault based on a fault code,
wherein the fault code is based on the second state.
