Abstract:In order to solve the problems caused by the increasing scale of transmission lines and the insufficient expansion of inspectors in recent years, such as the excessive per capita line maintenance, the deterioration of inspection quality, the inadequate planning of inspection paths and the unreasonable arrangement of travel vehicles, etc., to ensure the safe and stable operation of the power grid. This paper based on the pole and tower data of PMS2.0 system, the vehicle trajectory data of national network unified vehicle management platform and the pedestrian trajectory data recorded by PDA mobile handheld terminal, and combined with the navigation electronic map (offline version), this paper excavates the correlation and coupling among the data, deeply analyses the patrol habits of personnel, establishes the optimal planning path calculation model, and realizes the goal-to-object. The benchmarking tower''s automatic navigation and path-finding function improves the efficiency of line patrol through field verification; the line under the control of the team is meshed, and the periodic patrol plan and the special area patrol plan are optimized. The research results can provide strong decision-making basis for improving the flexibility of route inspection plan, planning reasonable route and arranging travel vehicles.
