摘要

这项贡献的重点是开发一种人工智能驱动的警报装置,以确保铁路轨道工人的安全。最近的研究清楚地表明,尽管实施了许多预防措施,但轨道工人的安全已成为铁路行业面临的主要挑战。在这方面,已经提出并开发了许多技术解决方案,以警告轨道工人接近的火车。然而,成本和复杂性是这些系统的缺点。因此,我们推出了TrackWarn,这是一种低成本的便携式智能设备,可以探测到驶近的火车的声音,并通过电话向跟踪工人提供警告信号。TrackWarn使用最先进的卷积神经网络(CNN),利用环境声音和频谱图来分类火车是否正在接近。该模型的平均分类准确率为92.46%。在Arduino Nano 33 BLE Sense微控制器的帮助下,整个系统变得非常方便便携。本文讨论了TrackWarn的设计和各种测试用例的结果。此外,还详细描述了性能和通信方面的挑战。

TrackWarn: An AI-driven warning system for railway track workers
This contribution focuses on developing an AI-driven warning device to ensure the safety of railway track workers. Recent studies clearly show that track workers safety has become a major challenge for the railway industry despite many precautionary measures that are implemented. In this regard, many technological solutions have been proposed and developed to warn track workers of the approaching trains. However, the cost and complexity are the drawbacks of these systems. Therefore, we introduce TrackWarn, a low-cost portable smart gadget that detects the sounds of the approaching trains and provides a warning signal to track workers via a phone call. TrackWarn uses a state-of-art Convolutional Neural Network (CNN) that utilizes environmental sounds and spectrograms to classify if the train is approaching or not. This model achieves an average classification accuracy of 92.46%. With the help of Arduino Nano 33 BLE Sense micro controller, the whole system becomes very handy and potable. This paper addresses the design of the TrackWarn and the results obtained with respect to the various test cases. Further, the performance and communication challenges are also described in detail.
