When this is done, it is possible to prevent uploading inspection data having an unnecessarily large amount of data to the management server 140. Therefore, the communication load when uploading the inspection data can be reduced as much as possible and the cost can be suppressed.

Abstract

L'invention concerne un système de gestion de données d'inspection comprenant un dispositif d'inspection et un dispositif de gestion apte à communiquer avec le dispositif d'inspection. Le dispositif d'inspection comprend : une unité d'acquisition de données d'image permettant d'acquérir des données d'image obtenues par l'imagerie d'une installation de production de gaz ; une unité de génération de données d'inspection permettant d'utiliser les données d'image acquises par l'unité d'acquisition de données d'image afin de générer, en fonction d'un niveau de quantité de données d'inspection spécifié par un utilisateur, des données d'inspection relatives à l'inspection de fuite de gaz de l'installation de production de gaz ; et une unité de transmission de données d'inspection permettant de transmettre les données d'inspection générées par l'unité de génération de données d'inspection au dispositif de gestion. Le dispositif de gestion comprend une unité de réception de données d'inspection permettant de recevoir les données d'inspection transmises en provenance de l'unité de transmission de données d'inspection et une unité de mémoire de données d'inspection permettant de mémoriser les données d'inspection reçues par l'unité de réception de données d'inspection.
