The Moisture Testing System for Ultra-Dry Granular Material

Article Preview

Abstract:

This paper discusses the design of moisture testing system for ultra-dry granular material. It designs from software and hardware aspects in detail. In hardware design, humidity sensor of HM1520 and data acquisition board of PXI-6070E are used; signal conversion between voltage and humidity is based on sensor circuit; PC is used to manage data acquisition and analysis. In software design, programming is based on LabVIEW2011, it included five models such as DAQ, alarm value judgment, data saving, data querying, data printing etc. In system, the data acquisition is based on PXI bus. It is easy to operate data because of using the access database and LabSQL. The system has the following advantages: graphical editing language improving the programming speed, its interface is friendly for users to understand and operate because of visual interface.
