Abstract
This report addresses the development of a measurement device for more
efficiency in the dynamic inspection of overhead lines, which is one type of
equipment inspection for the Kyushu Shinkansen.
With Shinkansen lines in the past, overhead lines were measured with special
electric and inspection cars using measurement pantographs and lasers. A testing
timetable had to be put together during the regular commercial service time. In
light of that, the Kyushu Railway Company (JR [Japan Railway] Kyushu) took
the following points into consideration, and developed a device for measurement
where imaging equipment is mounted to Shinkansen trains in commercial
operation to analyze the dynamic state of overhead lines by image analysis.
1) Enabling increased efficiency in maintenance by measuring on the normal
timetable during commercial service.
2) Reducing costs by eliminating the need for a special measuring car.
3) Simplifying the components that make up the measurement device.
With that measurement device, train location information and speed
information can be acquired from ATC (Automatic Train Control) to associate
those with test results at the points measured for better data management.
This measurement device is used periodically, and the data acquired is
utilized for maintenance and management of the overhead line equipment.
Keywords: Shinkansen, overhead contact line measurement, image processing,
stereo measuring, pattern recognition of shape.
