Operation management system

An operation management system for managing operation of electric drive vehicles, each of which is provided with two running modes, one being a trolley mode in which the electric drive vehicle runs by power supplied to overhead wires from a power plant or a substation, the other being a diesel mode in which the electric drive vehicle runs by power obtained from a generator driven by a diesel engine, comprising:

• a data reception unit for receiving a first data on a supply margin of power as transmitted from at least one of the power plant and the substation, a second data on a running position as transmitted from each electric drive vehicle, and a third data on a running mode as transmitted from each electric drive vehicle,
• a supply margin detection unit for detecting a current supply margin based on the first data,
• a running position detecting unit for detecting a current running position of the electric drive vehicle based on the second data,
• a running mode detection unit for detecting a current running mode of the electric drive vehicle based on the third data,
• a running mode determination unit for determining a next running mode of the electric drive vehicle 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 running mode, which has been determined by the running mode determination unit, to the electric drive vehicle,
• wherein, if plural ones of the electric drive vehicles, the running positions of said plural electric drive vehicles being in an area of the overhead wires and the running modes of said plural electric drive vehicles being the same, exist, the running mode instruction unit instructs, based on the running positions as detected by the running position detection unit, to switch the running modes in turn from the vehicle running at a head or tail of the plural electric drive vehicles.
