Design And Implement Of The Rapid Dispatching System Of Power Failure Repair Vehicles

With the sustained and fast development of national economy, the electric power industry,develops fast, with the sustainable expansion and the increasingly complicated structure ofpower wire. Meanwhile, the absolute quantity of break-down on distribution network in city andcountryside is rising rapidly. Therefore, when a fault occurs, power supply system to ensurerapid repair, how to improve the response speed of the power supply enterprises to the repairs ofthe power break-down is extremely urgent and the basic requirements to improve response speedis that repair vehicles and workers should arrive on the scene as quickly as possible, whichallows the power repair vehicles in a controlled condition all day so as to be dispatched in aquick and scientific way. At present, most of the regional power supply enterprises merely makesupervision and location to the repair vehicles avoiding speeding and illegal parking, without thesupport of scientific dispatching system.Under the practical requests of the management of regional power supply vehicles, thispaper will take advantage of GPRS (General Packet Radio Service), GPS (General PositionSystem) and GIS (Geographic Information System), together with the ready-made GIS map ofpower system to design and achieve conducting location to power repair break-down, on thebasis of which Dijkstra optimization algorithm will be employed to quickly dispatch themanagement system of power repair vehicles and to improve and expand the functionalapplication of the recent supervision system of power supply vehicles. Through the vehiclesequipment installed on every power repair vehicle, relevant information of the break-down andthe dispatching information of power repair vehicles can be achieved bi-pass via GPRS betweenpower repair vehicles and fast dispatching platform so as to provide all-round supervision of thevehicles in overall process and follow the tracks of the whole process, improving the dispatchingefficiency of power repair vehicles and guaranteeing the quick and efficient process of the workof power repair.This paper provides the design and achievement of some core modules, including vehiclemonitoring module, work order management module, break-down location and managementmodule, quick dispatching module applied Dijkstra optimization algorithm and system management module. The focus is to discuss how to use Dijkstra optimization algorithm toquickly search for the fittest repair vehicles around the area of power supply according to a fixedbreak-down spot and to provide the best way to ensure that the workers of power repair can relyon the system to make a quick decision and dispatch vehicles to the spot. The system meanwhileconducts priority strategy to the simultaneous break-down in break-down location module. Thepractice on probation proves that the system not only achieves the basic functions of location,supervision, tracking and track inquires to repair vehicles, but also achieves the choice of fittestway for repair vehicles and quick dispatching, shortening more than haif the time of dispatchingvehicles, improving the efficiency of break-down repair, and meanwhile providing technicalguarantee for the intelligent management of the repair vehicles in power system.
