An automatic standard device for roller type speedometer tester was developed. This device can be used to drive the roller type speedometer tester to the speed of 30 km/h, 40 km/h and 60 km/h for testing. This device can measure the speed of the roller, collect the speed tested by roller type speedometer tester, and have a comparison between this two speed. All the speed, rotating speed, oscillogram collected can be displayed on the touch screen for comparison. After testing and calibration, relative expanded uncertainty of the device is 0.6%. So the device can be used to test the roller type speedometer conveniently, quickly and accuracy.
