基于FPGA的安全级PLM在核电DCS中的应用

Application of FPGA in Nuclear Power Plant DCS Safety PLM

优先逻辑模块PLM是用于核电厂DCS不同安全等级之间控制命令优先权判断的一种底层逻辑判断设备,其性能直接影响核电厂的安全性。基于FPGA技术的PLM模块能够高速稳定的实现逻辑功能,成本较低,可扩展能力强,可靠性高。FPGA是一种实现核电厂0层接口优先级运算处理的最为合适的硬件平台。

Priority logic module is a Equipment to handle control signals come from different safety class in Nuclear Power Plant DCS control system.The performance of PLM will directly affect the safety of Nuclear Power Plant.The PLM developed with FPGA technology can perform the logic function with high speed and stability,low cost,and flexibility,high reliability.FPGA is a perfect develop platform to implement priority logic interfacing with level 0 device.
