KAZ axle counting system is a new generation of intelligent axle?counting system independently developed by Keanda, which?is an important signal equipment for the occupied / clear state?detection of urban rail transit. The system passes the SIL 4 safety?certification, as well as the NoBo and DeBo certification. The?system is widely used in railway stations, interval, field section,?level crossing control and other scenarios, to adapt to various?train and rail types and electrical and non-electrified railway?sections.
KAZ axle counting system can be widely used in: railway urban rail station, field, railway interval detection, crossing control, detection and control of train track crossing warning and other fields and scenarios.
Mainline
The signal from each wheel sensor (IDSS) can be used jointly by adjacent axle counting circuits to enable track free/occupancy checks for two adjacent track sections in sections with no switch. IDSS2 in the figure is reused, and is connected to adjacent sections.
Depot/Station Yard
The signal of each IDSS of single and split switches can be used jointly by adjacent axle counting circuits to achieve track occupancy/free detection in the sections with switch.
Axle Counting in Railway Sections
Axle counting in railway sections is for automatic block of single line and special line. By comparing the axle counted out at the starting station and the axle counted in at the receiving station, the state of occupied/clear between the stations can be detected, and the direction of train operation can be identified.
?Level crossing auxiliary monitoring axle counting
Through detecting and comparing the number of train axles that enter and leave the axle counting points at both ends of the track section, complete the automatic inspection of the free and occupied status of the track section, and realize the early warning and protection of the crossing.
Axle Counting for Auxiliary Detection of Train Passing the Track
The alarm system for detection of train passing the track can effectively confirm whether the train fully enters into the station track. This can solve the problem of not being able to detect the condition when the tail of the train does not sufficiently pass through the fouling post and the problem of no alarm when the train slips out of the station track.
●?Easy Installation and Maintenance
Outdoor wheel sensor only, easy installation?and maintenance and no need for grounding.?The system failure can be self-diagnosed,?troubleshooting is convenient and efficient,?
system maintenance cost is low.
●?Modulized design
The section circuit works?independently with decentralized?control, single failure has small?effect, with high system availability.
●?Standardized design
The same type of boards can be interchangeable,?system maintainability is high.
●?Low construction cost
Non- centralized station axle countingcan be distributed and controlled, optical fiber communication is used to save cable cost.
●??Detection accurate and stable,strong anti-interference
The wheel sensor is installed on the inner?side of the rail, with accuracy detection of?the wheel rim and strong anti-interference,?system availability is high.
