The contact-free photon system of measurement of a rail track contains the subsystem of level measurement of an inclination of a rail track monitoring car, velocity of driving and sample of pickets. This subsystem is implemented on the basis of optoelectronic sensors and Complex Programmable Logic Device (CPLD). The format of the transmitted data surveyed the calculation of parameters for a given accuracy and speed range is reduced. The outcomes and structure of the subsystem is shown. The value of a velocity is determined in notebook by an amount of going impulses from the optoelectronic sensor.
