Software Anti-Interference Design of SCM Control System

Abstract:

SCM control system requires high reliability and security, the entire control system to operate safely and reliably only when a strong anti-interference capability. In switch input and output, the use of the instruction redundancy methods to achieve the switch signal input and output filtering; in data collection, based on the hardware anti-interference taken arithmetic average filtering method, in order to strengthen its anti-jamming capability. In the system status monitoring, watchdog feature is enabled with the MSP430F449 microcontroller, when the watchdog timer overflows, the system automatically reset, the experiment proved that this method can save hardware resources, flexible design, low cost, single-chip control, it can guarantee the smooth operation of the system.
