Development of environmental measurement database for educational use

这项研究的主要目的是开发一个教育用的环境测量数据库，利用传感器(自动数据收集)和互联网(向公众开放数据)。此外，我们的目标是检查通过交换每个地方学校收集的当地数据而建立的测量网络。此外，我们还尝试在课堂上使用数据库，环境数据库是由测量传感器和联网的计算机构建的。测量项目有风向、风速、室内温度、室外温度、湿度、气压计、降雨量、紫外线辐射和太阳辐射。数据立即自动向公众开放。该系统已经在大阪、广岛和东京投入使用。最新数据和可选数据通过使用Java Applet和JavaScript的Web浏览器以图形方式显示。有关1998年9月23日途经大阪的第7号台风的资料已妥为分类，以便在课堂上使用，并附上适当的有关资料。讲座在合作学校举行，该系统有助于了解当地的天气现象。此外，我们正试图将地震和辐射传感器与该系统连接起来。

The main purpose of this research is to develop an environmental measurement database for educational use, utilizing sensors (automatic data gathering) and the Internet (opening data to the public). Furthermore we aim to examine the measurement network conformed by the exchange of local data gathered by each local school. In addition, we attempt to use the database in the classroom.The environmental database is constructed with sensors for measurement and computers connected to the Internet. Measuremental items are wind direction, wind speed, inside temperature, outside temperature, humidity, barometer, rain fall, UV radiation and solar radiation. Data are at once automatically opened to the public. The system is already being operated in Osaka, Hiroshima and Tokyo. The latest data and optional data are shown through a web brouser utilizing JavaApplet and JavaScript graphically. The data about typhoon number 7 which passed through Osaka in September 23 1998 were duly classified for classroom usage together with properly related information. The lectures are held in cooperation schools and this system is rendered useful for understanding local weather phenomena. Moreover, we are trying to link earthquake and radiation sensors to this system.
