Described the concept and type of redundant control. Aiming at the principle of redundant control, a redundant design method of airborne electronic equipment is proposed, which includes hard redundant design method and soft redundant design method. The working principle of hard redundant and soft redundant are respectively described in detail. Finally, the reliability of electronic devices with redundant designs is analyzed. The results show that the redundancy design method can significantly improve the mission reliability of electronic equipment, and can be applied to airborne electronic equipment to meet the operational requirements of high reliability of airborne electronic equipment.
