[0002] In the aviation field, the auxiliary power unit (APU system), as an important part of an aircraft, plays a crucial role. The main function of the APU system is to provide electric power and compressed air for the aircraft when the main engine of the aircraft is not operating, ensuring that the aircraft can maintain the operation of key systems during the ground stage or in-air emergency situations, including but not limited to cockpit lighting, air conditioning systems, power supply for electronic devices, etc. This system significantly improves the autonomy and flexibility of the aircraft and reduces the dependence on external ground equipment.

[0003] However, not all aircraft models are equipped with an APU system. To improve the safety performance and in-air emergency response ability of the aircraft, it is usually necessary to additionally install an APU system on aircraft models that do not have an APU system. Traditionally, the APU system usually consists of an auxiliary power unit (APU), an electronic control box (ECB), a generator (GEN), and a generator control unit (GCU). To enable these components to work together and to monitor and control the working status of the components in real time, there is an urgent need to provide a display controller for the APU system.
