PROBLEM TO BE SOLVED: To record and display an abnormal point of an overhead wire and a hanger position, at the time of overhead wire inspection, by associating with each other.SOLUTION: A trolley wire 16 and a suspension wire 17 are connected together by a plurality of hangers 18, 19. By using camera means 13, 14 mounted on a traveling vehicle, the trolley wire 16, the suspension wire 17, and the hangers 18, 19 are imaged. By processing an imaged picture, the hangers 18, 19 are specified. The information about a support point position and mileage measured in advance by an overhead wire inspection apparatus 30 and the information about the hangers 18, 19 (for example, information such as hanger number) are associated with each other and stored. By performing such series of processes for each hanger repeatedly, overhead abnormality or the like can be associated with the hanger position, allowing easy maintenance and management of an overhead wire. |
