Description

technical field [0001] The invention relates to the technical field of overall design and application of a control or regulation system, in particular to an electrical inspection type monitoring and control system. Background technique [0002] From the end of the last century, the wave of globalization has swept the world. Industrial globalization has driven the globalization of trade, resources, personnel exchanges, and military affairs. This trend of globalization has driven the aircraft industry to develop at an astonishing speed. [0003] The rapid development of the aircraft industry is mainly due to the rapid development of avionics technology in the same period. The avionics system is the sum of all electronic systems on the aircraft. It is the "brain" of the aircraft, and it carries most of the tasks of the aircraft such as communication, navigation, display management, and electronic countermeasures. With the improvement of aircraft endurance, the expansion of ent...
