Abstract

The embodiment of the invention provides a wireless multimedia sensor node system oriented to the field ecological monitoring. By virtue of a wireless multimedia sensor network in the shape of a net or a tree or a star or a cluster, a wireless multimedia sensor of the system sends the acquired multimedia information of a field environment after data processing and data fusion to a central monitoring station through a gateway node; and a solar photovoltaic generating set selects a charging strategy of constant voltage or constant current or maximum power point tracking or trickling charge by monitoring the electrical quantity of a storage battery in a real time manner, and provides proper voltage to each part of the wireless multimedia sensor through a DC-DC conversion circuit. The wireless multimedia sensor node system has low design cost, low power consumption and perfect function, can be suitably arranged in the field environment in large quantities, and can achieve better coverage; and meanwhile, the system is supplied electricity by a solar battery, so that the problem that the energy is limited when the wireless sensor network is arranged in the field can be solved.
