Abstract: The present disclosure is an optical line test system that detects a distribution of loss points of an optical line in a longitudinal direction, using a coherent light measurement device, applies vibration to facility disposed on a path of the optical line, detects a vibration point of the optical line in a longitudinal direction upon applying the vibration, using the coherent light measurement device, and identifies the loss point based on correspondence between the detected loss point and vibration point.

Abstract: An in-vehicle monitoring information generation control device includes: an image acquisition unit acquiring an image generated by capturing the inside of an unmanned vehicle; an abnormality determination unit determining whether or not an abnormality is occurring in the unmanned vehicle; an in-vehicle monitoring information generating unit generating in-vehicle monitoring information, with which no passenger in the unmanned vehicle who is captured in the image can be identified, on the basis of the image acquired by the image acquisition unit; and a transmission control unit transmitting the in-vehicle monitoring information generated by the in-vehicle monitoring information generating unit to the outside of the unmanned vehicle in a case where it is determined that no abnormality is occurring in the unmanned vehicle on the basis of a determination result determined by the abnormality determination unit.

Abstract: A receiving unit (20) receives pieces of request information indicating pieces of information requested by in-vehicle devices (3A to 3D) of vehicles (A to D) and pieces of condition information indicating the internal and external conditions of the vehicles (A to D). A delivery control unit (21) sets priorities for information transmission for types of respective pieces of information indicated by the pieces of request information and for the internal and external conditions of the vehicles (A to D) indicated by the pieces of condition information, and determines a transmission schedule for transmitting pieces of information to the in-vehicle devices (3A to 3D), on the basis of the priorities. A transmitting unit (22) transmits the pieces of information to the in-vehicle devices (3A to 3D), according to the transmission schedule.
