Abstract

PURPOSE: To enable the maintenance of power cables laid through a cave way or a man-hole section, to be monitored, by using an infrared ray camera.
CONSTITUTION: CV cables 8 are supported by troughs 12 or the like through a man-hole section 11 and are laid through a cave way 13. Then, one unit or a plurality of the units of infrared ray cameras 1 are arranged. When a plurality of the units of the infrared ray cameras 1 are arranged, then the geometrical position due to the triangulation or the like is to be clearly set. As the infrared ray camera 1, a unit for a high-performance thermograph with a semiconductor sensor for example or a unit for the high resolution of a linear sensor is adopted, and a secondary iris sensor system or the like can be applied. Then, the input of the information of the infrared ray camera 1, to a picture data processing unit 2 consisting of a computer and the like, through an optical fiber 7 is provided, and is converted to a picture data. As a result, by monitoring the CV cables 8 and their connecting sections 9, an information necessary to handle an abnormal state can be obtained.
