The research on emergency evacuation related supporting facilities has long been an important field of research in the field of civil aircraft safety. Due to the large and scattered number of personnel on board, when an aircraft encounters an emergency situation in the air and makes a forced landing on the ground, it is necessary to safely, quickly and orderly evacuate the personnel on board to the designated location outside the aircraft. One of the key factors for successful emergency evacuation is to quickly notify everyone on board of the emergency evacuation instructions. The emergency evacuation signal system establishes a fast and concise communication channel between pilots and crew members, and completes information communication through buttons, lights, and audio prompts, effectively improving the efficiency of emergency evacuation. In order to ensure the installation quality of the emergency evacuation signal system and improve the efficiency of development, an emergency evacuation signal system test bench has been designed, which can be used for comprehensive and complete functional testing of the emergency evacuation signal system on the ground.
