A study on construction of the agricultural water supply management system corresponding to the era of information

在机构更新换代即将到来的农业供水设施中，有一个机构在传统系统中由于成本较高而难以更新。本研究以互联网的迅速普及为目标，引入以网络为核心的信息技术，对构建廉价农业供水管理系统进行了基础性研究。通过使用移动电话和PDA等个人数字助理，建立了使更灵活的水管理成为可能的结构。此外，通过应用最新的传感器技术，成功地实时测量和存储现场信息，如农业天气和土壤湿度，并从大坝水库等用水设施到最终用户农场的紧密联系，完成了能够实现精确水管理和精确农业的系统。在整理研究成果时，1.开发了一套与现有气象监测系统(气象机器人)连接，自动采集观测值，并通过计算机网络登记入数据库的工具包；2.将密州阿诺大坝的水文气象观测数据转换为最新的PC也可以使用的形式，并登记在数据库中；3.建立了终端用户可以通过手机访问的文字和图像信息发布系统。该系统包括短期和长期出水池模型的入水量预测模拟程序，以及上述的数据库访问。

In the agricultural water supply facilities with which the updating time of an institution is coming, there is an institution where it is difficult to update for high cost in the conventional system. In this research, fundamental research on construction of a cheap agricultural water supply management system was done by introducing IT (information technology) centering on the network where the cost cut was aimed at dramatically with the rapid spread of the Internet. The structure that makes more flexible water management possible has been built by using personal digital assistants, such as a cellular phone and PDA. Moreover, making the system which enables precise water management and precise farming was completed by applying the latest sensor technology by succeeding in measuring and database-izing on-site information, such as the agricultural weather and soil moisture, on real time, and linking closely from water-use facilities, such as a dam reservoir, to a end-user farm. It is as follows when the result of this research is arranged,1.We have developed a kit, which connects the existing weather monitoring system (weather robot), collects observation values automatically, and registers them with the database through the computer network.2.Observation data of hydrologic and weather conditions in the Ano dam in Mie prefecture were transformed in the form that the latest PC can also be used, and registered in the database.3.The character and the image information distribution system that could be accessed by the end-user using their, cellular phone were built. This system involves the amount prediction simulation program of inflow by the short and long-term outflow tank model, and the database access mentioned above.
