Abstract

One of the new challenges in the railway industry, which is accompanied by an increase in the speed of trains and axial loads on trains, is the reliable detection of errors by monitoring the condition of equipment and rail infrastructure. Until the 1990s, the industry relied on time or distance-based preventive care, which is not always cost-effective and prone to error. Surveillance monitoring systems equipped with wireless sensor networks inspect train infrastructures such as bridges, rails, route platforms and equipment such as chassis, boogie and wheels and wagons by sensors and, in the event of an error, Inform to the railway control center. In this project, the purpose of designing and constructing a data collection system by wireless sensor networks installed on freight wagons to identify the humidity status to check the infiltration of water into the wagons and the temperature to monitor the heat inside the wagons. Some of these sensor nodes, which include a microcontroller, sensor, wireless module and battery, are installed inside the wagon. The sensor signals are then analyzed by microprocessors on the sensor nodes, and the information obtained from each node is transmitted to the central node by wireless modules. The database is stored and displayed on line graphs that show the changes of each sensor in specific sensors nodes over time. With this train system, the train control center, the railway control center and especially the stakeholders of the goods can be informed about the health status of the wagon and the cargo.
