Backup control system and method

摘要

A backup control system and method includes at least two system control modules and a power supply unit. The system control modules automatically detect the operating conditions of one another according to a determined logic of a backup control method. In the event that one system control module malfunctions, the operating condition is automatically transformed to continuing execute the control process and to enable that the power supply unit provides dynamically electric power according to loadings of the backup control system. Further, each system control module can automatically and immediately replace the other system control module to execute control processes and maintain the electronic equipment working, thereby reducing waste of electric resources.
