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 detecting
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. Рассматрива-
ется устройство и способ обнаружения обледенения или снега на контролируемой поверхности.
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.
