The calibration test of inertial accelerometer on precision centrifuge, involves exact measurement of dynamic radius and static radius, accurate control of wheel speed of precision centrifuge and signal acquisition of accelerometer calibrated, it needs control critically action timing logic of each test and control instrument to realize automatic operation of test and control and calibration test of accelerometer. An automatic system for test and control of precision centrifuge and accelerometer calibration test is introduced. For hardware, integrates instruments and builds distributed test and control system based on LAN bus, with external raster pulse signal as trigger signal to control timing synchronization logic of instruments; For software,applies net shared variable technique to realize kinds of test and control parameters sequence transmission, and for trustless reliability of big dynamic waveform data with shared variable technique, gives out a transmission project with file dynamic copying, and designs critical transmission mechanism of shared variable, realizes right acquisition and sequence transmission of kinds of parameters. Application test shows that this automatic system can fit automatic test and control of precision centrifuge and calibration test of accelerometer, improve calibration test efficiency remarkably. 
