Research and Design of IUR76-II Test System for Infrared Flame Detectors
IUR76-Ⅱ performance test system for infrared flame detectors is based on the National Standard of P.R.C,which is named as performance requirements and test methods for point infrared flame detectors (GB15631-1995). The architecture of new test system includes of infrared point source,optical track modulator,optical filter device,4-dimension holder,optical simulators,data collector,and computer. The common test is consisted of response threshold measurement,response time measurement,direction measurement,surrounding optical interference test,and power on test. In the new test system,SiC infrared source is used to replace the fire of the combusting gasified gasoline,which is used in national standard. The stability of SiC infrared source is smaller than 0.1%,which is much better than 20% (stability of the combusting gasified gasoline). The optical filter device is equipped with stepper motor. There are four bands infrared waves could pass through optical filter device,which are 4.2μm ~4.7μm wide band,4.32μm narrow band,4.45μm narrow band,4.58μm narrow band. The data collector and computer software is used in new test system to analyze measurement results and obtain quality reports for DUT. Based on the experience procedure and results,the new test system is proved more safe,convenient,and precision than the system proposed by national standard. This new test system for infrared flame detectors is applied in testing the point infrared flame detectors equipped in industrial or civilian buildings.
