Research Abstract

Natural energy is the focus of public attention as a clean substitutive energy for petroleum. In particular, photovoltaic solar power generation system is utilized for lighting as independent power source, and also begins to widen its sphere of activity in various fields.
In general, the battery has been used to store the electric power that is unstable and variable photovoltaic solar energy. However, using a battery, we must consider the maintenance such as supplement of electricity liquid and securing of the storage place. In addition to that, destruction of battery has harmful influences on the environment, so we cannot avoid these problems.
Therefore, the followings are required as a condition of independent power source.
1)To save the troublesome maintenance as much as possible.
2)To reduce harmful influences on environmental load.
In this research, we could overcome the above two requirements and develop a photovoltaic solar power generation system with an autonomous battery-less, which is the purpose of the irrigation water for agriculture. Furthermore, we succeeded to establish a supervisory remote control system by the internet.
Our main object is to build the remote measurement and control system of the agricultural growth condition in the greenhouse. To achieve that, the network communication system needs to be constructed based on wireless LAN and mobile PHS. To the consequence, we realize a fully automatic measurement and control system with no human labors.
