Foundations of automatic fault location turnouts
Development and implementation the points system diagnostics that would allow determining automated and remotely the current state of turnout with all possible faults, gradual and sudden failures, damages, and in real time to report about their appearance is very necessary task in the high-speed traffic functioning. State determining on the values analysis of turnout main parameters is proposed to carry out with the help of a computer and analog-to-digital converter. Connecting measurements performance is advisable to produce to a shunt ammeter, installed in the working circuit of the point feed panel. Using it one can analyze the obtained data of the dependence of the change in the amplitude of the current time and current amplitude spectrum, which allows diagnosing state of points upon change the nature and values of the current curve. The proposed method enables timely, still in the early stages of defect parts, malfunctions or failures of nodes mechanisms to detect and eliminate them.
