A Design of FPGA-Based Self-healing System for Communication Networks in Nuclear Safety DCS

For the nuclear safety communication system, at the moment of communication faults occurring, the fault should be detected and handled immediately, otherwise it will cause serious harm to the operation of nuclear power plants. In this paper, a FPGA-based self-healing system applied in safety communication networks is proposed, which could make the fault node isolated from the safety communication network and keep the network operating normally. The fault mode of the FirmNet is firstly analysed, followed by the requirement of the self-healing system being proposed. In addition, the method of designing a self-healing system has been stated, and the FPGA-Based self-healing system is implemented and contributes to the he reliability, safety, real-time, certainty and independency of the safety network. Finally, the FPGA-Based system is simulated and verified, which proved the system is designed in line with expectations.
