The theme of the final qualifying work: "Monitoring of failures in the information system of the subway." This work is devoted to improving the work of the metro station attendant's program to create a failure monitoring system in the C ++ programming language to calculate the probability of non-diagnosable and detailed diagnostics of the causes of diagnosed failures. Tasks that were solved during the study: 1. Study of the microprocessor-based subway centralization system. 2. Calculation of the probability of non-diagnosable failures. 3. Diagnosis of emerging failures 4. Development of software for monitoring failures of the metro information system. The work was carried out on the basis of JSC "NII TM", where all bench tests were carried out, the results of testing the probability of occurrence of undetectable failures and monitoring of diagnosed failures were collected. Various failure conditions of the PKFR, BUSFL, BUSF, BSU units were tested in accordance with the error codes. As a result, the testing of the probability of failures at the bench was carried out with an increase in the data exchange rate and the compliance with the calculated and required parameters was proved. The system was tested for compliance with safety requirements, according to which the probability of a dangerous failure in one year is no more than 8,1 ∙10-5 per signal point. As a result of testing, it was revealed that the first failure occurred after 1152 hours, which corresponds to the indicator of 7,9∙10-6 failure per year with the required failure probability no more than 8,1 ∙10-5 per year.
