【正文】 module. Also, data saving, printing, exporting, importing etc are all realized. 6) History query: according to the test number and fan type, users can find history records they need with numeric or graph type documents in this module. Thus, a needed test report including fan performance curve can be displayed and printed. 7) Experimental simulation: a visual flash film is designed for operator to know the operating procedure well. 8) System help: using the hyper text technology, the system help on line is built which consists of three parts, namely, fan performance test system overview, background knowledge and operating instruction. In conclusion, the software system has key functions as follows: autoacquiring parameters of fan performance, adjusting the rotating speed and flux of blower, autogenerating record of testing and performance curve, moreover, the software can also display, save and print these signals in graphic and numeric form. The whole system is friendly and convenient for operating. 4 Experiment of the system Take the centrifugal blower (472 type) for testing example in laboratory, the performance testing experiment was made with this system. As shown in , each point is the numerical value of test signal, and that connected line is the performance fitting curve based on least square method. Compared with handwork which was done at the same time, the two test results are nearly equal and the accuracy can pletely meet the needs of national standard 5 Conclusion From all above, the whole system has friendly functions, which can be used widely in scientific research institutes and factories. This system improves the stability of testing process, avoids the error of reading, calculation and result caused brelative data can not be recorded at the same time with test artificially. As a result, the precision an efficiency of testing is largely improved. It meets the need of scientific production and automanagement omodern industry.
