单片机在数字化脉冲周期监测装置中的应用

Application of SCM in Digital Pulse Period monitoring device

反应堆仪表和控制系统(I&C)的数字化发展方向成为趋势,反应堆堆外核测量系统的数字化势在必行。传统脉冲周期监测装置通常采用模拟电路设计,但是,周期测量稳定性较差,统计涨落带来的测量误差较大。本项目研制数字脉冲周期监测装置能克服以上缺陷。本文简单介绍了单片机在数字脉冲周期监测装置中的应用,并简要分析了使用80C196KC单片机的原因和在脉冲周期监测装置中单片机完成的功能和功能实现方法。

For the digitization development direction of reactor instrument and control system become a tendency, the digital nuclear measurement of exterior reactor is imperative under the situation. Analog circuit is introduced in traditional digital plus period monitoring device, however, the stability of period is not perfect and the measurement error caused by statistical fluctuation is biggish. The digital plus period measurement developed in this program can overcome bug mentioned above. The application of singlechip machines in digitized pulse period monitoring device is briefly introduced in this paper. Besides, the reason for using the 80C196KC as the CPU, the function and functional methodologies adopted by the single-chip machine in digitized pulse period monitoring device is analyzed in this paper.
