Abstract
Efficient perimeter intrusion detection approach is vital to safety management of China high-speed railway. In this article, for high-speed railway perimeter intrusion detection problem, a perimeter intrusion detection framework based on Internet of Things is designed to integrate different detection sensors. A data fusion algorithm was proposed to fuse multisensor data for improving detection precision. Computational results of normal condition and severe weather environment show our approach is effective and efficient for high-speed railway perimeter intrusion detection under Internet of Things, and is significant for safety management of China high-speed railway.

Summary
High-speed railway had a rapid development in China. At the end of 2017, ‘‘four vertical and four horizontal’’ high-speed railway transportation network has been built with lines in operation amounting to 30,000 km. With the rapid rise of operation mileages, safety management of high-speed railway faces great challenges, especially perimeter security. In order to timely detect these intrusion behaviors, manual inspection and device detection are both adopted. Because of the length of high-speed railway line, manual inspection is only used to assist and verify the information from device detection. The device detection is mainly video surveillance, and many sensors are set along the line of high-speed railway. Many sensors begin to detect, current detecting effect of high-speed railway perimeter intrusion is not satisfactory. The main problem for high-speed railway perimeter intrusion detection is the isolation of detection sensors, and different types of sensors lack interconnection. Advances in Mechanical Engineering improving detection precision of high-speed railway perimeter intrusion. Experimental results are reported in ‘‘Computational Experiments’’ section and ‘‘Conclusion’’ section covers the conclusion
