1、目的及意义（含国内外的研究现状分析）

1.1研究背景及意义

随着我国轨道交通特别是高速客运专线和城市轨道交通的快速发展，牵引供电系统发展迅速。强大可靠的供电是保证轨道交通正常运行的基本要求，牵引变电站是牵引供电系统中的重要环节，其安全运行是系统可靠运行的前提。

2. 研究的基本内容与方案

毕业设计希望针对牵引变电站，在前人研究行人检测和智能电站的基础上，对人体入侵这一具体问题展开研究。

因此，考虑将研究分为三个阶段来进行：采集数据、行人检测模型的实现、设计特征或指标区分正常的工作人员和闯入人员。

根据以往学者的研究与工作，行人检测的数据集一般采用加州理工大学的行人数据集(caltech predestrain)法国自动化所的数据集(inria).关于牵引变电站的人体数据的搜集，一方面来自于网络图片，其次来自于生产实习时的所拍摄的照片。
