1. Axis counting machine 
2. Counter-axis sensor 
The change of active magnetic steel induced magnetic field, active magnetic steel emits a positive pulse when the magnetic conductive object is close to the active magnetic steel, and the active magnetic steel outputs a voltage of 0V when the magnetic conductive object is approaching from the active magnetic steel.
Application solution
1. Determine the number of vehicles Pass the axle sensor to transmit the wheel information to the axle counting host. The axle counting host contains the algorithm of the intelligent axle counting. The number of vehicles can be directly transmitted to the upper computer software through the serial port.
2. Determining the occupancy and availability of the track section At both ends of the track section to be occupied and occupied, two sets of equipment are provided. The system will automatically determine the direction of the incoming vehicle, and accumulate or decrement the number of axes according to the direction of arrival. Final determination of track sector occupancy and availability
The active magnetic steel independently researched and developed by Dalian Qihui Computer Network Co., Ltd. has the advantages of short sensing distance, no need for analog-to-digital conversion, and the ability to detect low-speed vehicles. It can be widely applied to axle counting systems in railroad traffic safety systems. It is widely used in freight yards, locomotives, etc. The axle counting system can be used to determine the number of vehicles in the railway system, determine the type of vehicles, and determine the occupancy and idleness of track sections, providing high quality railway information management. solutions, following a brief part of <br> <br> axle counting system hardware system composition
