摘要
介绍了一种以智能手机作数据处理平台,溴化镧为探头,计数率大于100k/s(不失真)多道谱仪设计。详细介绍采集电路工作原理、蓝牙通讯及手机平台的软件设计。采集电路以PIC24H为核心实现堆积判断、基线恢复、谱数据生成,并将谱数据通过蓝牙模块发给智能手机;手机实现通讯、数据处理、人机交互、GPS功能。最后通过实验给出主要性能指标。
This paper introduces a Multi-Channel γ Spectrometer as smartphone for data processing platform,as LaBr3 for a probe,which count rate is more than 100 k/s without distortion.it describes in detail the principles of acquisition circuit,bluetooth communication and the software development on smartphone platforms.Acquisition circuit to PIC24H as the core can judge signal accumulation,achieve baseline restorer,generate energy spectrum and transmit the data to smart phones through the bluetooth module.Smartphone can process the data,interact with human,have GPS function.
