摘要
为适应宽量程中子监测装置处理反应堆功率及倍增周期信息的需要,本文结合裂变室探测器在坎贝尔工作模式下的信号特征,基于坎贝尔定理提出能够覆盖反应堆全量程范围的功率及倍增周期归一化信号处理算法,并利用FPGA技术完成了该算法的实现及验证。验证结果表明:利用归一化算法能够有效实现不同测量模式下不同量程间的“无缝”衔接,实现测量过程中功率及周期的准确及快速响应。
In order to meet the needs of reactor power and period double time information processing using wide range neutron monitoring device,this paper first introduced the signal characteristics of fission chamber detector under Campbell operation mode and proposes a normalized signal processing algorithm for power and period double time that covering the whole range of reactor based on Campbell theorem,that completes the implementation and verification of the algorithm based on FPGA technology.The verification results show that the normalization algorithm can effectively realize the seamless connection between different measurement ranges under different measurement modes,and the response of power and period double time in the measurement process is accurate and fast.
