Abstract
The concept and types of redundant control are described. Based on the principle of redundancy control, the design method of redundant system for airborne electronic equipments is put forward, including the design methods of hardware redundancy and software redundancy, and the principles of hardware redundancy and software redundancy are described respectively in detail. And the reliability of the electronic equipment adopting redundant design is analyzed. The results show that the design method of the redundant system can significantly improve the mission reliability of the electronic equipment, and can be applied to the airborne electronic equipment, which can meet operational reliability requirements of the airborne electronic equipment.
