ALGORITHMS OF THE CONTROL PROGRAM OF AUTOMATIC CLEANING SYSTEMS OF THE TURNOUTS BASED ON THE SENSOR FOR DETERMINING ICE OR SNOW ON THE CONTROLLED SURFACE

Abstract

The structure of an automatic system for cleaning turnouts is considered, the main advantages and disadvantages of precipitation sensors of existing automatic systems for cleaning turnouts are analyzed. It is concluded that it is necessary to develop an advanced system based on a sensor for de- tecting ice or snow on a controlled surface. The developed block diagram of the formation of control actions of the system for detecting icing or snow on the controlled surface is presented. An algorithm is given for its technical implementation, as well as for measuring the anticipatory control of the process of electric heating of the controlled surface of the switches. The results of simulation of the device and method for determining ice or snow on a controlled surface in the Matlab Simulink environment are presented.
