利用北京谱仪Ⅲ上的干燥系统提供的干空气,整合小型温湿度一体探头、智能采集模块、开关量控制模块和普通气体电磁阀,基于LabVIEW图形化编程环境开发了一套多路湿度控制系统.此系统可同时实现多个不同湿度小环境的实时监测和控制,并可以扩展到多路温湿度的混合控制,单路湿度可以控制在空气湿度以下直至相对湿度低于3%的任意值,湿度控制误差好于2%.%A real time multi -channel humidity control system was designed based on LabVIEW, using the dry air branch of BESIII drying system. The hardware of this control system consist of mini humidity and temperatare sensors, intelligent collection module, switch quantity controller and electromagnetic valves. The humidity can be controlled at arbitrary value from air humidity to 3％ with accuracy better than 2％. Multi microenvironments with different humidity can be easily controlled and monitored in real time by this system. It can also be extended to hybrid control of multi channel humidity and temperature.
