The System of Water-Saving Irrigation based on WSN and MSIF
Confronted by the population mushroomed and the increasing
shortage of water around the world today, water-saving irrigation
and intensive cultivation are inevitable and viable. In this paper,
the auto water-saving irrigation based on wireless sensors
networks and multi-source information fusion technology based
on entropy is introduced. Using wireless sensors networks which
adopts nRF2401 as transfer modual, collecting and fusing multisource
information from crop growing environment at remote
monitoring center such as soil moisture and temperature and the
CO2 content, information about intensity of illumination realtime,
it is realized to auto water-saving irrigation according to
control strategy which is given by expert database about the
demand for crops growth. Adopted solar batteries to
supplying the current, using multi-level memory management
and multi-level energy storage mechanism, it converts the solar
into electric and makes the system becoming self-sufficient in
energy. Combined with low power consumption and algorithm of
multi-sensor planning and management based on entropy, it is
significance for energy-saving and consumption reducing, and it
is convenient and flexible and precise for automatic saving-water
irrigation. The results of practical application verify the
reliability and efficiency of the design strategy of system. Also
the system can be used in greenhouse and regional farmland and
large irrigation area.
