We have developed a sensor called a point current sensor, aiming at a system which can combine small radios, networks and proprietary web servers to automatically measure river flow and can deliver in real-time. Since the point current sensor is compact, inexpensive, consumes less power based on the simple principle using a reed switch. It is suitable for combination with a wireless device and is unnecessary to construct a large-scale cable under the river bed, therefore it is easy to install. In this paper, we explain the idea of the flow rate measurement system, the principle of a point current sensor and the solution method of the problem found in the field experiment so far and also show the development situation of the whole system."},{"@language":"ja","@value":"河川等の流量把握方法はこれまで多くの研究開発が為されてきていて国内外で実用化されているが，河川の低水から高水までを自動で連続観測できる方法は我々が知る限り存在していない．我々は新たに点流速センサと呼ばれるセンサを開発し，小型無線機，ネットワーク及び独自のウエブサーバを組み合わせ，河川流量を自動無人連続観測でき，かつリアルタイム配信可能なシステムを目指している．点流速センサはリードスイッチを用いた簡単な原理に基づいた，小型，安価，無電源であり，無線機と組み合わせることで，河床下の大規模なケーブル埋設工事は基本的に不要であることから複数設置が容易である．本稿では，流量観測システムとしての考え方，点流速センサの原理やこれまで現地実験で判明した課題の解決手法等を説明し，システム全体の開発状況を示すものである．"}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410572173902698753","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000386228582"},{"@type":"NRID","@value":"9000378070380"}],"foaf:name":[{"@language":"ja","@value":"鶴岡 重信"},{"@language":"en","@value":"TSURUOKA Shigenobu"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"株式会社拓和 新技術開発センター 開発課"}]},{"@id":"https://cir.nii.ac.jp/crid/1410572173902698754","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000386228584"},{"@type":"NRID","@value":"9000378070382"}],"foaf:name":[{"@language":"ja","@value":"深沼 二葉"},{"@language":"en","@value":"FUKANUMA Futaba"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"日本大学大学院理工学研究科 情報科学専攻"}]},{"@id":"https://cir.nii.ac.jp/crid/1410282680332249089","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000386228583"},{"@type":"NRID","@value":"9000378070381"}],"foaf:name":[{"@language":"en","@value":"BANEPALI Anu"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"株式会社拓和 新技術開発センター 開発課"}]},{"@id":"https://cir.nii.ac.jp/crid/1420282801200806656","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"70534220"},{"@type":"NRID","@value":"1000070534220"},{"@type":"NRID","@value":"9000240235828"},{"@type":"NRID","@value":"9000021446594"},{"@type":"NRID","@value":"9000045430943"},{"@type":"NRID","@value":"9000386228585"},{"@type":"NRID","@value":"9000406397482"},{"@type":"NRID","@value":"9000405706997"},{"@type":"NRID","@value":"9000331081942"},{"@type":"NRID","@value":"9000021956794"},{"@type":"NRID","@value":"9000340442979"},{"@type":"NRID","@value":"9000331083125"},{"@type":"NRID","@value":"9000398783915"},{"@type":"NRID","@value":"9000388993925"},{"@type":"NRID","@value":"9000330333672"},{"@type":"NRID","@value":"9000409185522"},{"@type":"NRID","@value":"9000398828291"},{"@type":"NRID","@value":"9000241156149"},{"@type":"NRID","@value":"9000311056609"},{"@type":"NRID","@value":"9000267846947"},{"@type":"NRID","@value":"9000323839634"},{"@type":"NRID","@value":"9000378070383"},{"@type":"NRID","@value":"9000408570876"},{"@type":"NRID","@value":"9000309175297"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/7000005592"}],"foaf:name":[{"@language":"ja","@value":"松野 裕"},{"@language":"en","@value":"MATSUNO Yutaka"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"日本大学 理工学部応用情報工学科"}]}],"publication":{"publicationIdentifier":[{"@type":"EISSN","@value":"21856591"},{"@type":"NDL_BIB_ID","@value":"024054586"}],"prism:publicationName":[{"@language":"en","@value":"Journal of Japan Society of Civil Engineers, Ser.
