摘　　要：针对当前对能谱采集系统智能化、小型低功耗、易扩展的要求,引进了MSP432微处理器。滤波成形方面,设计了多重负反馈型二阶积分电路,以替代Sallen-Key滤波器。峰值保持电路方面,进行了针对性设计。智能化硬件方面,引入了TFT触摸屏,软件架构中也移植整合了μC/OS和μC/GUI。该能谱采集系统已应用到氡污染测量仪中。To meet the current requirements of intelligent,low power consumption, compact size and easy extendibility on en- ergy spectral acquisition system, MSP432 microprocessor was introduced. Multi-feedback two-order integral circuit filter was designed on the side of pulse shaping to replace Sallen-Key filter . Targeted was design on peak-holding circuit. In the intelligent hardware, a TFT touch-screen was introduced and the μC/OS and μC/GUI was transplanted and integrated in the software structure.The designed energy spectral acquisition system is successfully applied to the radon pollution monitoring instrument.
