Airplane APU working condition monitoring system for airport

Provided is an airplane APU working condition monitoring system for an airport. The system comprises an infrared temperature sensor, an image sensor, an electric pan-tilt, a main controller and an Ethernet communication module. The infrared temperature sensor and the image sensor are arranged on the electric pan-tilt. The infrared temperature sensor is connected with the main controller. The image sensor is connected with the main controller. The electric pan-tilt is connected with the main controller connected with the Ethernet communication module through a data bus and an RS-232 interface or an RS-485 interface. The airplane APU working condition monitoring system for the airport has the advantages that first, real-time and automatic monitoring of the working condition of an APU in the process of airplane ground operation can be achieved without installing sensors or communication devices on an airplane; second, the non-contact type detection technology is adopted in the system, so that no influence on the airplane and the ground operation of the airplane is caused; third, the system can automatically adjust the detecting direction to be adapted to the positions of exhaust ports of APUs of different models.
