Real Time System for Measuring the Pantograph Vertically Position Correlated with Temperature and Air Humidity

This paper presents a system used for measuring the pantograph vertically position correlated with temperature and air humidity, system which nowadays is used in railway transportation infrastructure. The real time measurement technology is ensured by a system which contains NI (National Instruments) MyRIO controller equipped with FPGA (Field Programmable Gate Array) system, connected to a Laser distance sensor and also to a humidity and temperature measurement sensor. Data can be monitored and saved into. txt file documents.
