Remote Access Dual Automatic Switch Spray

Abstract: The RADASS (Remote Access Dual Automatic Switch Spray) system is thought to be the future solution for frozen rail switches. Frozen switches are a yearly reoccurring issue and cause long delays in rail traffic, which require a vast amount of personnel and resources to fix. Spraying chemicals manually by railway workers is the most common method to deal with the issue; the system intends to automatize the process. For the system to be self-going, it will need sensors that measures weather and other prerequisites for dispensing. Sensors are also needed so that the user can be kept informed of the systems well-being and warned if there are risks for malfunctions. The sensors are in focus in this thesis work and are chosen and implemented after specifications made by Solliq (developer of RADASS). A lot of measurements are able to be performed with sensors already on the market, while other measurements or circumstances require innovative uses and development of sensors. One of these innovative attempts is to use accelerometers to measure wind speed and direction.
