Abstract

This study proposes a multi-interface gateway and a dual backhaul communication architecture to enhance real-time safety monitoring and communication reliability of power maintenance vehicles. The proposed gateway integrates LTE, UWB, CAN, GPS, and Wi-Fi/BLE interfaces to collect in-vehicle data and transmits them securely to the control center using MQTT-based telemetry and VPN encryption. Moreover, a failover mechanism from LTE to TV White Space (TVWS) is applied to maintain communication continuity under LTE degradation or outage. A prototype gateway board was implemented and validated through functional and performance evaluations. Experimental results confirmed that key performance metrics—latency, throughput, packet delivery, and VPN session continuity—meet operational requirements, demonstrating stable data transmission even during LTE-to-TVWS switchover. This work provides a practical foundation for deploying intelligent safety and monitoring systems for power maintenance vehicles. Future work includes field-level validation in real operation environments and performance improvement for long-term stability.

본 연구에서는 전력설비 유지보수 차량의 실시간 안전 관리 및 통신 안정성 확보를 위해 다중 통신 기반 게이트웨이 및 백홀 구조를 제안하였다. 게이트웨이는 LTE, UWB, CAN, GPS, Wi-Fi/BLE 인터페이스를 통합하여 차량 내부 데이터를 수집하며, MQTT 기반 Telemetry 송신, 보안 기반 VPN 전송을 적용하여 데이터 전송의 무결성과 신뢰성을 확보하였다. 또한 LTE 장애 발생 시 TVWS 기반으로 자동 전환되는 이중 백홀 구조를 통해 통신 연속성을 유지하도록 설계하였다. 제작된 프로토타입 게이트웨이 보드를 활용하여 데이터 송수신 기능과 성능 검증을 수행하였으며, 실험 결과 데이터 지연, 처리량, VPN 세션 연속성 등 주요 지표가 요구 기준을 만족함을 확인하였다. 특히 LTE→TVWS 전환 시에도 세션이 유지되어 제어 신호 전달이 끊기지 않음을 검증하였다. 본 연구는 전력설비 유지보수 차량의 안전 모니터링·설비 상태 진단·위험 대응 시스템 구현을 위한 실질적 기반을 확보하였으며, 향후 실제 현장 차량에 적용하여 장기 운영 안정성 검증과 통신 품질 최적화를 위한 추가 연구를 수행할 계획이다.
