Modelling the pulse of a double wheel sensor

Abstract [en]

Axle counting system is an application to monitor track section vacancy and to ensure railway safety. The aim of this study is to develop a mathematical model for a pulse from train wheel detection sensor for a simulator. The simulator simulates a train wheel detection sensor known as double wheel sensor. The double wheel sensor is attached to the railway track, and it sends pulses each time a train wheel passes it. The simulator is designed to send similar pulses as the original double wheel sensor to the counting system. The research for this study is carried out at Mipro Oy in Mikkeli, Finland. It is a medium sized company, which specializes in customised automation. One of its main business fields is safety related systems in railways. Mipro Oy has two test locations for axle counting testing with real train traffic. The need for a proper simulator has arisen to ensure the safety of an axle counting system, and to make its further development possible in a cost efficient way. If a simulator described in this study were to be built, it would be possible to test the axle counting system more efficiently, since a real train can be replaced by a simulator. By having a better ability to test the system, it becomes more reliable, and safety level of the axle counting system increases.
