BO23 is a multisection based axle counter system used for train detection applications. It consists of BO23 evaluator, trackside control unit VUR and wheel sensor ZK24-2. BO23 axle counter is a well established and proven solution on multiple global markets, operating under various conditions and in a variety of applications.
BO23 uses wheel detection technology. One indoor unit controls up to 8 counting points configured up to 6 sections (selection of 9 predefined configurations) . The system proved its performance in railway, tram and metro applications. Axle counting can be performed at train speeds up to 350 km/h.
The system is developed and certified according to standards EN 50126, EN 50128 and EN 50129 for the highest safety integrity level SIL4, as well as EN 50125-3 for harsh environmental conditions and EN 50121-4 for EMC. BO23 is assessed and certified by TÜV Rheinland.
There is no need for complex maintenance activities. System maintenance includes periodical reviews of the installed indoor and outdoor equipment. Reviews include simple and fast checks of sensor ZK24-2 and BO23 evaluator using special tools which are easy to operate.
System analytics is designed to be user friendly and may be done by the Customer independently using software for BO23 diagnostics.
