Abstract:
The Remote Safety Blocking System is intended for locomotives, rail shunting or maintenance vehicles, and other rail vehicles. It remotely provides an efficient blockage against movements, with high operational security and at a viable cost for small, medium and large fleets. For that end, it applies a wireless network incorporated into control devices with an optimized size that are robust in operation, resistance and security, and a software capable of providing redundant security, operational performance in low to medium signal latency networks, and which have a record of operations to analyze process metrics and KPIs generation. The greatest challenge was meeting all operational, security and cost requirements, the most complicated being the need to adapt the system to existing standards and norms for security blocking. During the tests and after the implementation of the MVP, the impossibility of using wireless networks in the 2.4GHz frequency was uncovered, due to the climatic characteristics of certain regions. Given the specificities of the network, the resulting product for the proposed solution met all operational, safety and cost requirements, ensuring efficiency, accuracy and operational safety for maintenance activities of freight or passenger wagons inside and outside workshops, protection for service fronts on the railways and during boarding at passenger stations.
