BO23-A Axle Counter

BO23-A Axle Counter

BO23 is a multisection based axle counter system used for train detection applications. It consists of BO23-A evaluator, trackside control unit VUR-A and wheel sensor ZK24-2FMA. BO23-A axle counter is a robust and exceptionally resilient solution used in harsh environments for reliable and safe train detection.

Functionality

The system is flexible and can be paired with regular ALTPRO wheel sensors as well as „M“ sensor series. By processing raw analogue signals from wheel sensors directly beside the rail, BO23-A shows great results in harsh environments. As signal is processed directly at its source, there is no possibility for it to be influenced on its path to the indoor unit. The system shows exceptional results in railwheel distinguishing from other metal objects and adaptation to environmental influences like temperature change, EMI, overvoltage, traction currents, different rail and wheel/train profiles, worn-out flanges and rails. Furthermore, implemented self adjustment to aging of system components and preventive maintenance features increase the availability of the system.

RAMS

High availability levels are achieved using advanced system intelligent processes for self-adjustment and project specific adjustments in order to have best operation in each particular application. BO23-A is certified according to the relevant CENELEC standards (EN50238, EN50126, EN50128, EN50129, EN50121-4, EN50125-3) and latest EU legislation satisfying safety integrity level SIL4.

Maintenance

There is no need for complex maintenance works. System maintenance includes periodical reviews of installed indoor and outdoor equipment. Reviews include simple and fast checks of sensor and evaluator using tools which are easy to operate. There are no active components beside the track, only overvoltage protection. Preventive maintenance features are implemented at counting point level (wheel sensor – UP2-A module).

Analytics

System analytics is designed to be user friendly and may be done by the Customer independently using software for diagnostics. Diagnostics can be accessed locally or remotely.

Connectivity

Possibility of interfacing with relay and electronic signalling systems. Output information is sent by safety relays. Safety direction outputs are also available. If SEC module (remote communications module) is used, Ethernet RJ45 connection of the SEC module is available for connection to a certain network.
