The goal of automating the railway transport is to decrease the influence of human factor in the management system and thus increase its safety. During repetitive work, the worker's attention and awareness decrease, leading to possible mistakes, which can turn into serious accidents. With interlocking, we can safely and reliably control railway traffic. The diploma thesis describes the process of combining two types of interlocking, i.e., relay and electronic, that comprise a device for interstation dependency. With the latter, verbal arrangements for traffic management between the stations are no longer needed. With the help of an axle counter system, the device controls vacancy of the block section and the logical functions of the relays, which protects the train from frontal threats and prevents it from overtaking the other train.
In this diploma thesis, the operation and functions of several different types of interlocking are presented, as well as interstation dependency for securing the block sections between stations. The work includes a description of the processing of the relay group of the interstation dependency, which is adapted for axle counters, the production of software for axle counters and diagnostics. Axle counter system from manufacturer Frauscher Sensortechnik was used to control the sections. A dedicated test stand was designed for testing purposes. The final result of this thesis is a functional device that ensures safe and reliable operation of the device interstation dependency
