Power amplifier system capable of monitoring fault

The invention relates to a power amplifier system capable of monitoring the fault. The power amplifier system capable of monitoring the fault is technologically characterized in that a state monitoring is mounted in each functional module; a state acquiring unit, a fault warning unit and a state sending unit are mounted in a main control module; each state monitoring unit can automatically acquire the working data of each functional module and transmit to the state acquiring unit of the main control module through a motherboard; and the main control module analyzes and processes the working data and sends warning information through the fault warning unit and the state sending unit in case of fault. The power amplifier system capable of monitoring the fault is reasonable in design; the state monitoring units are arranged in all functional modules and used for monitoring the state data of the functional modules and sending to the main control module in real time, and the main control module analyzes and treats the state data and sends the fault alarming information by a plurality of ways in case of the fault, and thus the maintenance staff can receive the fault warning information as soon as possible and make an effective decision within the shortest time to reduce the resulting loss.
