Axle counter PN-02

Axle counter is a device, which is able to register a railway carriage wheel passing over it. System of axle counter consists of several subsystems. One subsystem is placed close to rails and another is placed in a technology room. There are wheel sensors and converters placed in the rails yard. Evaluation unit, power sources and batteries are placed in the technology room.

System of the Axle Counter PN-02 consists of:

  • Outdoor equipment:

    • Sensor PN-SPK02, which detects a wheel pass-trough and the direction, is installed at the rail. Our fastening assembly allows installing the sensor without the need of disruption and drilling a rail. Fastening assembly allows both vertical and horizontal positioning of the sensor. It can be used for all usual types of rails (e.g. S49, R65, UIC66). Converter PN-PPN02 evaluates analogue signals from the sensor PN-SPK02 and processes them digital form. Converter also controls sensor and provides self-diagnostics. Resulted digital data are sent over a leased line to the evaluation unit. Converter is placed on the stand, which is placed in the ballast.

  • Indoor equipment:

    • Evaluation unit of the axle counter PN-02 receives the data from converters, process them and evaluates an occupation of a corresponding track circuit. Occupancy of a track circuit is signalled by two inversed digital outputs. LCD display of the evaluation unit shows occupancy of the monitored track circuit, number of axles, error messages, results of self-tests and configuration parameters. The evaluation unit allows emergency remote reset of a track circuit. Evaluation unit is produced as an embedded case, which is usually installed in a rack of 19” dimension. (both sizes are possible : 3U, 6U ). The evaluation unit is usually installed in a technology room, where safety relays are usually installed.
