The main and standby modules achieve real-time synchronization of input signals, operation logic, output status, and alarm information via a dedicated high-speed synchronization bus (synchronization speed ≤1μs). During operation, they continuously perform mutual health checks, data verification, and clock synchronization. When the main module encounters faults such as processor failure, I/O channel abnormality, communication interruption, or power fluctuation, the standby module can automatically switch to take over the control task without disturbance within ≤2ms. During the switching process, control commands are not interrupted, output parameters are not fluctuated, and equipment operation is not impacted, ensuring continuous and stable operation of power equipment. The module has built-in fault diagnosis and fault-tolerance mechanisms, which can perform real-time monitoring of the core processor, memory, I/O channels, communication interfaces, and power circuits. When a fault is detected, it immediately triggers a local alarm (LED indicator), uploads the fault code, and automatically initiates redundancy switching. The system's Mean Time Between Failures (MTBF) is ≥100,000 hours.
