Can a small group of drones (无人机) guarantee the safety and reliability of railways and, at the same time, help railway operators save billions of euros each year? That is the very likely future of applying today’s “eyes in the sky” technology to making sure that the millions of kilometres of rail tracks and infrastructure (基础设施) worldwide are safe for trains on a 24/7 basis.
Drones are already being used to examine high-tension electrical lines. They could do precisely the same thing to inspect railway lines and other vital aspects of rail infrastructure such as the correct position of railway tracks and switching points. The more regularly they can be inspected, the more railway safety, reliability and on-time performance will be improved. Costs would be cut and operations would be more efficient (高效) across the board.
That includes huge savings in maintenance costs and better protection of railway personnel safety. It is calculated that European railways alone spend approximately 20 billion euros a year on maintenance, including sending maintenance staff, often at night, to inspect and repair the rail infrastructure. That can be dangerous work that could be avoided with drones assisting the crews’ efforts.
By using the latest technologies, drones could also start providing higher-value services for railways, detecting faults in the rail or switches, before they can cause any safety problems. To perform these tasks, drones for rail don’t need to be flying overhead. Engineers are now working on a new concept: the rail drones of the future. They will be moving on the track ahead of the train, and programmed to run autonomously. Very small drones with advanced sensors and AI and travelling ahead of the train could guide it like a co-pilot. With their ability to see ahead, they could signal any problem, so that fast-moving trains would be able to react in time.
一小群无人机能(无人机) 确保铁路的安全性和可靠性,同时帮助铁路运营商每年节省数十亿欧元?这是应用今天的“天空之眼”技术确保数百万公里铁轨和基础设施的未来(基础设施) 全世界的列车都是全天候安全的。
无人机已经被用于检查高压电线。他们可以做同样的事情来检查铁路线和铁路基础设施的其他重要方面,如铁轨和道岔的正确位置。越是定期检查,铁路的安全性、可靠性和准时性就越能得到提高。成本将被削减,运营效率将提高(高效) 全面。
这包括大幅节省维护成本和更好地保护铁路人员安全。据计算,仅欧洲铁路每年就花费约200亿欧元用于维护,包括派遣维护人员(通常在夜间)检查和修复铁路基础设施。这可能是一项危险的工作,无人机协助机组人员可以避免这项工作。
通过使用最新技术,无人机还可以开始为铁路提供更高价值的服务,在铁路或道岔出现故障之前检测出故障。为了执行这些任务,铁路无人机不需要在头顶上飞行。工程师们正在研究一个新概念:未来的轨道无人机。它们将在列车前方的轨道上移动,并被编程为自主运行。配备先进传感器和人工智能的超小型无人机可以像副驾驶一样引导列车。凭借他们的预见能力,他们可以发出任何问题的信号,以便快速行驶的列车能够及时做出反应。
