发明名称 Operation management system
摘要 An operation management system obviates such a situation that a power substation would trip and a supply of power to overhead wires would stop. The operation management system controls operation of electric drive vehicles, each of which is provided with a trolley mode, in which the electric drive vehicle runs by power supplied to the overhead wires, and a diesel mode, in which the electric drive vehicle runs by an output from an engine. A supply margin detection unit detects a current supply margin of power and a running position detecting unit detects a current running position of the electric drive vehicle. A running mode detection unit detects a current running mode of the electric drive vehicle and a running mode determination unit determines a next running mode based on the detection results of the supply margin detection unit, running position detecting unit, and running mode detection unit.

主权项 1. An operation management system for managing operation of a plurality of electric drive vehicles, each of which is provided with two running modes including a trolley mode in which the respective one of the electric drive vehicles runs by power supplied by overhead wires from a power plant or a substation and a diesel mode in which the respective one of the electric drive vehicles runs by power obtained from a generator driven by a diesel engine, the operation management system being installed in a management station and connected to communicate with the electric drive vehicles via a communication network, the operation management system comprising: a data reception unit for receiving first data on a supply margin of power as transmitted from at least one of the power plant and the substation, second data on respective running positions as transmitted from each of the electric drive vehicles over the network, and third data of the respective running modes as transmitted from each of the electric drive vehicles over the network; a supply margin detection unit for detecting a current supply margin based on the first data; a running position detecting unit for detecting current running positions of the respective electric drive vehicles based on the second data; a running mode detection unit for detecting current running modes of the respective electric drive vehicles based on the third data; a running mode determination unit for determining next running modes of the respective electric drive vehicles based on detection results by the supply margin detection unit, running position detecting unit, and running mode detection unit; and a running mode instruction unit for instructing the next running modes, which have been determined by the running mode determination unit, to the respective electric drive vehicles over the network, wherein when the respective running positions of said electric drive vehicles are in an area of the overhead wires and the respective running modes of said plural electric drive vehicles are the same, the running mode instruction unit instructs, based on the respective running positions as detected by the running position detection unit, to switch the respective running modes in turn from one of the electric drive vehicles running at a head or a tail of the electric drive vehicles.
