미분말 수소흡탈장 DAQ 시스템 설계
Design of a DAQ System for a Hydriding/Dehydriding System
A hydriding/dehydriding DAQ (Data Acquisition) system has been designed and fabricated to measure the temperature and pressure exactly for a twosome SDS (Storage and Delivery System) bed. A DAQ program has been prepared by using a LabVIEW 2010. A DAQ system was composed of sensors, signals, signal conditioning, DAQ hardware, and DAQ software. The signals between temperature and pressure sensors and DAQ devices, a personal computer, have been sent and received by using a LAN (Local Area Network) protocol. The noise reduction and SNR (Signal-to-Noise Ratio) amplification have enabled the measurements of temperature/pressure from DAQ devices to be easy. The personal computer has enabled the control of pumps/heaters. In emergencies, manual manipulations have enabled the control of pumps. The control of heaters for dehydriding and vacuum annealing has been performed by using a PID (Proportional Integral Derivative) control system.
