The core structure of UniAC is divided into indoor and outdoor equipment.
The UniAC system is based on modular architecture that enables various implementation possibilities of the Axle Counting System.
Software and Hardware are designed to be ready for future needs, especially integration with different types of Interlocking systems, via safe and secure communication protocols.
The Indoor Equipment is placed either in a centralized signal room or decentralized. Main part it is the Multipurpose Module AXM, responsible for evaluation, counting and communication functions.
The Outdoor Equipment consists of the Wheel Sensor Units UniAS and UniAS. Mounted by a modular and flexible fixation – no drilling needed – the Wheel Sensor Units are responsible to to detect bypassing wheels on the track.
GUI tools supporting the whole Life-Cycle of the UniAC Axle Counting System
The powerful evaluation, counting and communication module is the core of our UniAC
Main system functions are performed by a combination of multipurpose modules - AXM. This one type of the module, depending on configuration, can perform all required functions of the Axle Counting System.
The configuration of the AXM module is not stored on the module itself, but at the slot where a wheel sensor is connected to, simplyfing the mainteannce process.
The AXM module is built out of newest electronic components and can therefore reach MTBF times above 1.000.000 hours.
Additonally, to the standard AXM multipurpose module, a version with Relay extensions (AXMR) and safe Out- and Inputs is available.
The Multipurpose Module AXM provides
AXM supplies the wheel sensor with power, evaluates analog signals from the outdoor equipment and converts them into a digital ones. Additionally, every cable fault is detected and an alarm is generated.
AXM is responsible for the vital communication with the subsequent signaling system via Protocol, Optocoupler or Relay. As well the AXM Multipurpose boards handles the internal communication.
AXM provides 4 independent counting units within one module. Each Counting Unit can consist of up to 16 counting points. With this numbers of counters, many special functions can be configured without needing additional hard- or software.
AXM provides extended diagnostic functions via its screen and provides them to the Advanced Diagnostic Modules where the data could be accessed in various ways.
