Beam scanning and data sampling of the system are controlled by the interrupt handler triggered by an external cyclic signal. We can monitor the condition of the system and obtain data from a remote station even while the system is busy for observation, because the system runs on a multi-task operating system. In this paper, we describe the performance of the system and some results of task delay measurement when the CPU is under a heavy load. The measured task delay for cyclic signals was within 30μs, which is negligible for data sampling period (12.5ms) and beam scanning (125ms) period. These results show that the system can control beam scanning and data sampling under a heavy CPU load.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00009250","subitem_identifier_reg_type":"JaLC"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00181831","subitem_source_identifier_type":"NCID"}]},"item_1_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00857289","subitem_source_identifier_type":"ISSN"}]},"item_1_subject_21":{"attribute_name":"国際十進分類法","attribute_value_mlt":[{"subitem_subject":"62(*2)","subitem_subject_scheme":"UDC"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research/National Institute of Polar Research"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"国立極地研究所/国立極地研究所"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2002-11-01"}],"displaytype":"detail","filename":"KJ00000139294.pdf","filesize":[{"value":"355.1 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000139294","url":"https://nipr.repo.nii.ac.jp/record/9250/files/KJ00000139294.pdf"},"version_id":"394c0076-4d9d-4d2f-80b7-c04d6d310fa9"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"マルチタスクOSを用いたイメージングリオメータ制御部の開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"マルチタスクOSを用いたイメージングリオメータ制御部の開発"},{"subitem_title":"Development of the imaging riometer control system on a multi-task operating system","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["1135"],"pubdate":{"attribute_name":"公開日","attribute_value":"2002-11-01"},"publish_date":"2002-11-01","publish_status":"0","recid":"9250","relation_version_is_last":true,"title":["マルチタスクOSを用いたイメージングリオメータ制御部の開発"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T14:17:47.280484+00:00"}
