Abstract: A cable sequence detection method and a detection system. A base station antenna includes N ports, an RRU includes M antenna ports and one calibration port, any port i of the base station antenna corresponds to a directional coupling branch Ti, and a switch circuit Ki whose connection and disconnection are controlled by an RCU is disposed on the Ti. The method includes: the RRU sends a detection signal to the base station antenna through antenna port j; the RCU controls the switch circuit Ki to be disconnected and another switch circuit to be connected; the RRU detects whether energy Qi obtained by the Ti is greater than a threshold; and the RRU determines whether the antenna port j of the RRU is connected to the port i of the base station antenna according to whether Qi is greater than the threshold.

Abstract: The present application discloses a radio frequency system, includes a detection device, at least one antenna line device, and an antenna that are sequentially connected in series by using a radio frequency channel. Each of the at least one antenna line device is configured to: receive a detection signal from the detection device or a previous antenna line device connected in series to the antenna line device; and add device information of the antenna line device to the received detection signal, and send, to the antenna or a next antenna line device connected in series to the antenna line device, the detection signal to which the device information is added. The detection device obtain device information of each of devices connected in series on a radio frequency line, to determine whether a connection relationship between the devices is correct, and determine a specific port location at which an error occurs.
