the fault processing module is further configured to send a fault signal to a background monitoring system when any one of the standby power amplifiers receives a fault level sent by the faulty main power amplifier; and the fault signal comprises the position information and the fault time of the main power amplifier with the fault.
10. The system of claim 6, further comprising:
the timing switching module is used for acquiring the running time of each main power amplifier in real time; the method comprises the steps of comparing the running time of each main power amplifier with a preset time threshold, if the running time of the main power amplifier is longer than the preset time threshold, adjusting a first switch corresponding to the main power amplifier to be in an off state, adjusting a first switch corresponding to any one standby power amplifier to be in an on state, taking a second switch corresponding to the main power amplifier as a fourth switch, adjusting a second switch connected with the fourth switch in a second selector corresponding to the standby power amplifier to be in an on state, and adjusting other second switches corresponding to the standby power amplifiers to be in off states.
