Construction of conditional algorithm for diagnosticsof tonal rail circuits on station

The article deals with the possibility of applying a conditional diagnostic algorithm, applied to a specific problem of searching for damage in a station's tonal track circuit. The aim of the work is to substantiate the possibility of applying diagnostic algorithms, in order to reduce the time of search and repair of damages. The order of compiling the diagnostic algorithm is shown, conditional probabilities, diagnostic weights, private and general diagnostic values are calculated. On the basis of the calculations performed, a conditional algorithm for diagnosing the tonal track circuit was compiled. The advantages of the conditional diagnostic algorithm in relation to the unconditional algorithm are demonstrated. The results obtained in the article can be used for technical maintenance of automation systems of operating railways.
