摘　　要：该装置能够对滚筒式车速台滚筒的带动,实现30km/h、40km/h、60km/h的控制,实时测量转速值,采集滚筒式车速表检验台的速度,并将两者速度进行比较;能够直观地将采集到的速度、转速、波形图显示在触摸屏上,便于观察和比较;装置的相对扩展不确定度为0.6%,可以方便、快速、准确地对滚筒式车速表检验台进行检定校准。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 krn/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.
