Abstract: | To promote the localization of the third generation of digital nuclear power protection system AP1000,the research and development of diverse actuation system(DAS) is carried out.The system consists of conditioning module,set-point module,communication module and display module,and in secure channel,CPU is replaced by FPGA,to implement UART asynchronous communication protocol and SPI serial communication protocol.The system possesses the functions of set-point comparison and RAM data readable symbolization,etc.Long term running shows that FPGA structure-based system can implement data acquisition,communication and output accurately and reliably,and the demand for security of nuclear power protection system is satisfied. |
