The first optical filter allows only infrared rays included in a predetermined wavelength band to pass among the infrared rays that have passed through the first optical system.

　以上詳しく説明したように、本実施の形態における検査データ管理システム１０は、検査装置１２０と、検査装置１２０と通信可能な管理装置（管理サーバー１４０）とを備える。検査装置１２０は、ガス生産施設を撮像して得られた画像データ（赤外画像データ）を取得する画像データ取得部（画像処理部１２２）と、画像データ取得部により取得された画像データに基づいて、ガス生産施設に対してのガスの漏洩検査に関する検査データを、ユーザーに指定された当該検査データのデータ量のレベルに応じて生成する検査データ生成部（検査データ生成送信部１３０）と、検査データ生成部により生成された検査データを管理装置に送信する検査データ送信部（検査データ生成送信部１３０）とを有する。管理装置は、検査データ送信部から送信された検査データを受信する検査データ受信部１４２と、検査データ受信部１４２により受信された検査データを記憶する検査データ記憶部（記憶部１４４）とを有する。 As described in detail above, the inspection data management system 10 in the present embodiment includes an inspection device 120 and a management device (management server 140) capable of communicating with the inspection device 120. The inspection device 120 is based on an image data acquisition unit (image processing unit 122) that acquires image data (infrared image data) obtained by imaging a gas production facility and an image data acquired by the image data acquisition unit. An inspection data generation unit (inspection data generation transmission unit 130) that generates inspection data related to gas leakage inspection for a gas production facility according to the level of the data amount of the inspection data specified by the user. It has an inspection data transmission unit (inspection data generation transmission unit 130) that transmits the inspection data generated by the inspection data generation unit to the management device. The management device has an inspection data receiving unit 142 that receives inspection data transmitted from the inspection data transmitting unit, and an inspection data storage unit (storage unit 144) that stores the inspection data received by the inspection data receiving unit 142. ..
　このように構成した本実施の形態によれば、ユーザーが管理サーバー１４０を利用する目的の違いに応じてデータ量のレベルが指定され、指定されたレベルに応じて検査データが生成されて管理サーバー１４０に送信される。これにより、管理サーバー１４０を利用する目的に適合するデータ量のレベルで検査データが管理サーバー１４０にアップロードされる。そのため、例えば、ユーザーが管理サーバー１４０を利用する目的として管理目的を所望している場合、第１の予測目的、第２の予測目的または第３の予測目的に対応するデータ量で検査データが生成される場合、管理サーバー１４０に対して不必要にデータ量が多い検査データのアップロードを防止することができる。したがって、検査データをアップロードする際における通信負荷を出来るだけ低減するとともにコストを抑えることができる。 According to the present embodiment configured in this way, the level of the amount of data is specified according to the difference in the purpose for which the user uses the management server 140, and the inspection data is generated according to the specified level of the management server. It is transmitted to 140. As a result, the inspection data is uploaded to the management server 140 at a level of the amount of data suitable for the purpose of using the management server 140. Therefore, for example, when the user desires a management purpose for the purpose of using the management server 140, the inspection data is generated with the amount of data corresponding to the first prediction purpose, the second prediction purpose, or the third prediction purpose. 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.
　なお、上記実施の形態では、何れも本発明を実施するにあたっての具体化の一例を示したものに過ぎず、これらによって本発明の技術的範囲が限定的に解釈されてはならないものである。すなわち、本発明はその要旨、またはその主要な特徴から逸脱することなく、様々な形で実施することができる。 It should be noted that the above embodiments are merely examples of embodiment of the present invention, and the technical scope of the present invention should not be construed in a limited manner by these. That is, the present invention can be implemented in various forms without departing from its gist or its main features.
