Concentrator of railway axles counters

The project is based on the design, development and validation of the System of a Hub Counter Concentrator, used to detect the integrity, presence and occupation of the train along the entire railway track. The axis counter is an electromagnetic safety system, consisting of directional pedals and subsystems that detect, count and control the number of axes that pass over the track. It is designed to anticipate any contingency of failure that may arise and, in this way, ensure that it does not affect the establishment of safe driving. The mechanism provides reliability to train traffic and provides information on the state of the tracks (free and busy), allowing proper circulation. It works by sections of certain length (canton), in which devices are installed at the beginning and at the end, responsible for counting the number of axes that pass over it. A canton is considered occupied when the first axis of the train accesses it, at which time the entry counter is activated; It is also considered free when the last axis passes through the output counter, leaving the canton. To be considered a successful operation, the subtraction of input and output axes will have to result in zero, an action that guarantees that the train has completely released the canton. The Hub Counter Concentrator is responsible for gathering information on the sections of track from the messages sent by the axle counters of an area and transmitting it to the electronic interlocking, as well as transferring the possible interlocking orders to them.
