Research of boron concentration measurement of nuclear power plant based on SOPC

According to the requirements of the integrated and miniaturization boron concentration measurement system, the data acquisition system based on SOPC (System on a programmable chip) achieves the acquisition of the pulse signals and temperature signals, and can decrease the transmitting interference and improve the accuracy of boron concentration measurement. According to the principle of boron concentration measurement, this paper firstly introduces the structure of the data acquisition system, and then carries on the detailed research on temperature acquisition module, pulse acquisition module, digital potentiometer, self-test control module, on-sit display module and telecommunication module. So the multifunctional data acquisition system is integrated into a more complete and flexible SOPC. At last, the testing results verify the reliability, accuracy and anti-jamming capability of boron concentration measurement system based on SOPC. (authors)
