The Jiaxun Railway Perimeter Intrusion Detection System, jointly developed by Jiaxun Feihong and Huawei, is an integrated, intelligent security solution for railway perimeter protection. The system combines vibration fiber optics, millimeter-wave radar and video surveillance, enabling all-weather, long-range, real-time intrusion detection and early warning.

Driven by advanced multi-dimensional data fusion algorithms and deep neural anti-interference models, the system achieves zero missed alarms and an ultra-low false alarm rate, effectively intrusion prevention, mitigating infrastructure security risks, and establishing a resilient safety barrier along railway perimeters.

By integrating multi-source sensing data with GIS geographic information, it enables end-to-end visualization，covering the full range from station sections to individual devices. All device statuses are clearly displayed on the GIS map, with real-time alerts for abnormalities and one-click positioning, enabling rapid situational awareness and swift incident response.

The system leverages vibration fiber and millimeter-wave radar technologies to accurately distinguish human and large-animal intrusions. Complemented by AI-driven video analysis, it enables automated target tracking, intelligent false alarm filtering, and delivers an alarm accuracy rate exceeding 99%.

Through multi-source data fusion, the system generates real-time dynamic risk heatmaps and supports multi-level alerting, enabling precise coordinate-based threat localization within seconds. This empowers decision-makers with timely, actionable intelligence for risk mitigation and response.

Multi-source data fusion generates dynamic risk heatmaps, with multi-level alerts enabling risk coordinate localization within second, thereby facilitating rapid response and decision-making by management.

Built upon a closed-loop architecture of “Sensing – Verification – Decision”, the system significantly enhances response efficiency, reduces reliance on manual verification, and achieves millisecond-level response latency, delivering intelligent, automated, and high-performance protection for railway perimeter security.
