【摘要】：介紹了一種具有快速硬件自觸發(fā)功能的數(shù)據(jù)采集前端的設(shè)計(jì),針對(duì)大面積多探測(cè)點(diǎn)的高能宇宙線實(shí)驗(yàn)的特殊情況,提出了獨(dú)立自觸發(fā)、數(shù)字化和數(shù)字濾波的實(shí)現(xiàn)方案。通過(guò)靈活的板級(jí)控制和兼容的PCB管腳設(shè)計(jì),提供比較靈活的采樣速率和采樣精度的調(diào)整,以滿足不同的需求。通過(guò)不同濾波器參數(shù)設(shè)置,實(shí)現(xiàn)對(duì)不同干擾信號(hào)的排除,完成信號(hào)的有效探測(cè)。
[Abstract]:This paper introduces the design of a data acquisition front-end with fast hardware auto-trigger function. According to the special situation of high-energy cosmic ray experiment with large area and multiple detection points, the realization scheme of independent self-trigger, digitization and digital filtering is proposed. Through flexible board level control and compatible PCB pin design, flexible sampling rate and precision adjustment are provided to meet different requirements. By setting different filter parameters, the different interference signals can be eliminated and the signal can be detected effectively.
