The invention provides an airborne fire alarm detection system. The system is used for performing fire alarm detection on a left engine and a right engine. The airborne fire alarm detection system comprises a plurality of first temperature sensors and a plurality of second temperature sensors, the first temperature sensors and the second temperature sensors are arranged in a left engine compartment and a right engine compartment, the first temperature sensors form a first detection channel and a second detection channel, and the second temperature sensors form a third detection channel and a fourth detection channel; the system further comprises a first remote interface unit connected with the first detection channel and the third detection channel, and a second remote interface unit connected with the second detection channel and the fourth detection channel, and the remote interface units detect a fire alarm in a corresponding engine compartment according to a temperature sensor signal of the corresponding detection channel and gives an alarm; and the system further comprises a data processing module which is connected with the first remote interface unit and the second remote interface unit and gives an alarm according to the fire alarm information of the remote interface units. Compared with an original detection system, the airborne fire alarm detection system has the advantage that the redundancy of fire alarm detection is improved.
