In　order　to　improve　the　efficiency　of　nucleic　acid　detection　and　code　allocation,　inform　the　health　of　tested　personnel,　reduce　labor　costs　and　the　possibility　of　medical　personnel　being　infected,　this　paper　uses　the　reliability　of　DCS　and　stratification,　integration　of　mechanical　arm　technology,　real-time　fluorescent　RT-PCR　technology,　distributed　control　system,　using　LabVIEW　software　system　design　and　simulation.　Through　the　determination　of　nucleic　acid　detection　results　and　the　monitoring　and　management　of　historical　data,　the　communication　system　can　precisely　assign　codes　to　all　kinds　of　personnel,　notify　each　place　to　seal　the　pipe,　and　provide　data　feedback　to　relevant　personnel,　so　as　to　help　determine　the　size　of　the　sealed　area　and　other　purposes.　©　2023　SPIE.
