Abstract

An optoelectronic device on CCD for measuring velocity is quite a new meter intended for measuring velocity of a locomotive by contactless optical methods with further high- precision determination of a covered distance. The device uses an optical image of railway as well as preliminary velocity values received from other devices installed on the locomotive. Velocity measurement range is from 0 to 250 km/h. The measurement accuracy is 0.5%. The operating principle is based on the use of unique features of a dedicated CCD chip. Owing to a special photozone structure the device can execute moving image filtering according to velocity. Further processing and calculations make it possible to obtain an actual value of velocity in real time mode.
