【Abstract】 In this system, two-level structure including high level computer 80386 and low level microprocessor 8098 is taken. The microcontroller 8098 Performs signal transmitting and data gathering, and 80386 performs data calculation and result output. The accuracy is improved by testing flow with a grating sensor. The result is that the efficiency of testing electrohydrau1ie servo valve is improved.更多还原
