摘　　要：核仪器电源系统对仪器测量的结果有较大影响,为了尽量降低这种影响,本文提出了一种低功耗的核仪器多路电源监测方案。该方案以低功耗MSP430F6638处理器为核心,通过多路调理电路、模数转换电路、通信接口及显示单元等部分对核分析检测仪器的电源系统进行监测,动态测量电源输出电压的变化情况,一旦超出阈值范围可即时进行告警提示,避免因电源不稳定而降低分析测量结果的可靠性和准确性。经测试本文设计的多路电源监测系统能实时监测低压电源、高压电源,且功耗较低,可满足现行核仪器的使用要求。Power supply system of nuclear instrument has a great influence on the results of instrument′s measurement, in order to minimize the effect;this paper proposes a scheme of multi-channel power monitoring on nuclear equipment.With ultralow power processor, MSP430F6638, as the core, including multi -channel modulation circuits, analog-to-digital conversion circuit, communication interface and display unit, etc.The scheme can monitor the power supply system of nuclear instrumentation, dynamic display the change of voltage. Once the threshold range is exceeded, an alarm is immediately prompted to avoid the decrease of reliability and accuracy on the measurement results.After testing, the design of low-power multipath monitoring system can in real-time monitor low voltage power, high voltage power, and can meet the requirements of the current nuclear instruments.
