This paper develops fast-repairment command system to realize fault real-time monitoring and fault point fast localization,prompt notice correlation owner and related technical personnel,navigate and the most superior path,assign to arrive the fault point the best parking and the intelligent demonstration most superior walk route and finally promptly repairs in a rush the faulty line by the shortest time. It reduces the fault point location time,seeks frugal arrives the fault point path the time,realizes the fast emergency repair. The system researches fault location, the best repairment path, and relevant GIS data.It also designs the best stopping location,which has higher telligence and practiveness.
