In the paper the principle of on-line automatic identification system of plant condition is studied appling the self-organization network and topography search method in knowledge processing.

In the Network Era-that age we have just entered-dense communication is creating artificial worlds ripe for emergent coevolution, spontaneous self-organization, and win-win cooperation.

Based on expatiated the basic structure model and some general improved algorithms of BP neural network, this paper brings forward a new self-organization learning algorithm.
