Problems solved by technology

In the electronic system using hot backup, since the main and backup machines are working at the same time, when one of the redundancy fails, the system will be downgraded to single redundancy, which can still ensure that the system function will not be affected, but the way of hot backup is adopted It will increase the power consumption of the system, and it is not economical for space missions with relatively tight energy supply

Description

technical field [0001] The invention belongs to the technical field of control and information processing in aerospace electronic systems, and in particular relates to an electronic system utilizing dual-computer backup to realize control and information processing. Background technique [0002] Due to the high reliability requirements of aerospace electronic systems, in order to ensure the smooth implementation of space missions, a dual-machine backup scheme is usually adopted. Dual-machine backup is divided into two different forms: cold backup and hot backup. Cold backup refers to the redundant backup mode in which the main machine works and the standby machine does not work. Hot backup refers to the redundant backup mode in which the main machine and the standby machine are in working state at the same time. The advantage of using the cold backup working mode is that when the main machine is working, the backup machine is not working, which can improve system redundancy ...
