Abstract: Provided are a delay time measurement server, a delay time measurement method, and a program for calculating a video display delay time without arranging a special device on the client side. The delay time measurement server calculates a video transmission delay time from when a video signal obtained by encoding a specific video is transmitted toward a monitor until when a reaction signal for the specific video is received, as a video display delay time from when the video signal is transmitted toward the monitor until when the video is displayed on the monitor.

Abstract: A battery unit of an automated guided vehicle comprises a casing installed in a chassis of the automated guided vehicle, a battery housed in the casing, a control panel housed in the casing to monitor a charge and discharge state of the battery, and electric components housed in the casing and electrically connected to the battery. The battery is arranged in the casing such that a battery bottom surface is separated from the casing bottom surface.

Abstract: Disclosed is a battery charging management system of an automated guided vehicle that travels in an unpiloted manner by using a mounted battery as a driving source, the mounted battery being charged in a charging station, wherein a battery charging controller that monitors a remaining capacity of the mounted battery is mounted on the automated guided vehicle, the battery charging controller starts a charging operation for the mounted battery in the charging station when the remaining capacity of the battery is lower than a predetermined value, and a charging route of the vehicle is cut off when a charging amount of the mounted battery reaches a predetermined capacity during the charging operation.

Abstract: A system for detecting an abnormality of an automated guided vehicle that travels on a circulation route includes: a history recording unit for recording a change history of a current of a battery of the automated guided vehicle with respect to each circulation; and an abnormality determining unit for determining presence or absence of an abnormality of the automated guided vehicle on the basis of the change history of the current of the battery recorded for each circulation.

Abstract: A battery charging management system for an automated guided vehicle that travels in an unpiloted manner by using a battery as a driving power source and performs a charging operation for the battery using a battery charger provided in a charging station, comprises a charge/discharge monitoring part that monitors a charge/discharge amount of the battery, a charging needlessness threshold voltage setting part that sets a charging needlessness threshold voltage for the battery, and a charging control part that performs the charging operation for the battery using the battery charger when it is determined that a voltage of the battery of the automated guided vehicle arriving at the charging station is lower than the charging needlessness threshold voltage set by the charging needlessness threshold voltage setting part. The charging needlessness threshold voltage setting part is configured to lower the charging needlessness threshold voltage during a particularly set time period.

Abstract: A system for managing charging of each of a plurality of automated guided vehicles that travels on an orbiting route in an unmanned manner using a battery mounted thereon as a driving source, in which the battery is charged at a charging station installed at a predetermined position on the orbiting route, includes: an after-charging voltage recording unit for recording a voltage after charging at the charging station for each of the automated guided vehicles; a charge priority setting unit for setting up charge priority of each of the automated guided vehicles on the basis of voltage values of voltages after charging recorded in the after-charging voltage recording unit; and a charging target value setting unit for setting up a charging target value of each of the automated guided vehicles on the basis of the charge priorities set up by the charge priority setting unit.
