The article discusses the solution of the problem inherent in railway automation and telemechanic systems using axle counting sensors - building a fault-tolerant and safe microprocessor system with respect to specified failures. in as researching the system is presented microprocessor a semi-automatic interlocking, where the presence of rolling stock performs axle counting. Based on simulation tests, a comparison of the fault tolerance and safety of such systems has been performed.

    One of the methods to reduce the aging rate of railway automation and telemechanic systems in conditions of insufficient funding is the use of axle counting sensors instead of track circuits in control systems and centralization systems and blocking (CCS) railway transport of common use. First of all, railway automation systems, axle counting systems have better technical and economic indicators than similar systems using track circuits. On the modernized sections of the track, they can be implemented as systems for detecting rolling stock instead of outdated signaling equipment, in stages, practically without stopping traffic on the section [1]. In addition, the functionality of axle counting sensors is broader than the functionality of track circuits.

    But there are problems with the use of inductive sensors for registering a railway wheel. during their operation, malfunctions are possible, namely the effect of weather conditions, location, the effect of rail magnetization. The article discusses one of the possible failures, it is the influence of the magnetization of the rail on the failure of the axle counting. Traditionally, the consequences of malfunctions in axle counting are neutralized by logistic methods using a much larger amount of equipment than required to solve specific functional problems. This negates the main advantages of using axle counting sensors instead of track circuits.
