1. A control system for controlling a radio base station, comprising:
a power supply system;
a backup power supply system;
a direct current power distributor;
a baseband unit (BBU);
at least one remote radio unit (RRU), and
a central monitor,
wherein an input port of the direct current power distributor is connected to direct current ports of the power supply system and the backup power supply system,
wherein the BBU and the RRU are respectively connected to direct current power supply ports of the direct current power distributor using power cables,
wherein the BBU is communicatively connected to the RRU using a common public radio interface (CPRI),
wherein the central monitor is communicatively connected to the BBU and is connected to a direct current power supply port of the direct current power distributor using a first power cable,
wherein the central monitor is configured to:
receive RRU control information that is transmitted by the BBU and comprises a control instruction;
modulate the RRU control information onto the first power cable; and
transmit the RRU control information to the direct current power distributor,
wherein the direct current power distributor is configured to transmit the RRU control information to the RRU using a second power cable, and
wherein the RRU is configured to:
demodulate, from the second power cable, the RRU control information comprising the control instruction; and
perform a corresponding control operation in response to the control instruction.
