8. The system of claim 1, wherein if the BBU power module determines that the main control board is faulty, it attempts to restart the main control board by powering on and powering off once;
if the BBU power supply module judges that the base band board fails, the base band board which fails is restarted by power on and off once;
if the RRU power supply module judges that the corresponding optical signal receiving and transmitting system fails, the RRU power supply module tries to power up and down once to restart the corresponding optical signal receiving and transmitting system;
if the RRU power supply module judges that the corresponding radio frequency receiving and transmitting system has a fault, the RRU power supply module tries to restart the corresponding radio frequency receiving and transmitting system by powering on and powering off once;
and if the RRU power supply module judges that the signal detection device in communication connection with the RRU fails, the RRU power supply module tries to power up and down once to restart the corresponding signal detection device.
9. The system of claim 1, wherein the BBU power module is communicatively coupled to the main control board via a backplane, the RRU power module is communicatively coupled to the signal detection device via an internal bus, and the signal detection device is communicatively coupled to the optical signal transceiver system via an internal bus.
10. The system of claim 1, wherein the baseband board and the signal detection device are communicatively coupled via optical fibers.
