Abstract: A content presentation system includes: a trainee terminal that presents training content to the trainee; a worker terminal used by a worker; a tool recognition device that acquires a work video of the worker and recognizes the tool being used by the worker; a determination device that determines success or failure of the work at a specific stage based on the information about the work tool recognized by the tool recognition device; and a content creation device that creates and updates the training content based on the determination result of the determination device. When the determination result is determined to be the failure of the work by the determination device, the content creation device identifies a portion of the training content corresponding to the specific stage in the work procedure and updates the portion of the training content so as to suppress a factor of the failure.

Abstract: The present invention relates to an aircraft-utilizing deterioration diagnostic system and provides a technique capable of improving diagnostic efficiency and accuracy when comparing the previous and current aerially-photographed images to diagnose a deteriorated state of a target. The diagnostic system includes: a drone 1 (aircraft) configured to be navigated along a route around a target 5 and having a camera 4 configured to photograph the target 5; and a computer (PC 2 and server 3) configured to control navigation of the aircraft and photographing by the camera 4. The computer is configured to: acquire data from the aircraft including an image group obtained by consecutively photographing the target 5 for each predetermined date and time; based on diagnostic data including a diagnostic image group photographed at a current date and time, reference data including a reference image group of a previous date and time, associate, for the same target 5, images including the same portion as comparison target images; compare the previous image and the current image among the comparison target images to detect a deteriorate portion; and provide a screen converted and visualized for the user such that the deteriorated portion in the image is plotted on the three-dimensional model of the target.

Abstract: A photovoltaic inspection system is provided, the photovoltaic inspection system detecting a failure by eliminating ON/OFF operation of a switch or others at the time of inspection or checkup as much as possible, reducing an influence of a temperature distribution as a whole with a small effort, and detecting a local deterioration in a photovoltaic module or string. According to a typical embodiment, in a photovoltaic system having a plurality of photovoltaic strings formed of one or a plurality of photovoltaic modules arranged to be aligned, a photovoltaic inspection system which detects the failure in the photovoltaic strings includes: a current detector which measures each of a first output current of a first photovoltaic string and a second output current of a second photovoltaic string; and a monitoring unit which calculates a second temperature property of the second photovoltaic string based on a value of the first output current and a value of the second output current and which determines whether the second photovoltaic string has the failure or not based on the second temperature property.

Abstract: The training management server 3 and the site management server 6 of the content presentation system 1 that presents a training content, when predetermined information that can be an accident occurrence factor in the on-site work of the work target device from a predetermined three-dimensional body motion of the trainee R1 or the model worker R2, adjust the evaluation criterion information on the work operation in the specific stage or other stage of the work procedure of the on-site work related to the information. At that time, the training content is updated so as to increase a probability of occurrence of a simulated accident with respect to the work operation in the specific stage or other stage during the simulated work, and impress the trainee R1 with the occurrence of the accident at occurrence of the simulated accident.

Abstract: A content presentation system includes: a training content distribution function 431 that presents the training content to the trainee; a work content delivery function 331 that presents a work procedure based on augmented reality; a user operation detection unit 120 that detects a three-dimensional operation of the site worker; a work record analysis function 338 that determines success or failure of the work based on the evaluation reference information; and a content creation/updating function 342 that updates the training content based on the determination result. When a predetermined body motion of the worker is detected, the work record analysis function determines whether the work has failed based on the measurement information of the model worker up to the body motion. When the work is determined to have failed, the content creation/updating function updates the training content so as to suppress the factor of the failure.
