Research of the path optimization in agricultural water-saving irrigation and canal system water distribution in Ant colony algorithm

To realize the management and control of the water-saving irrigation of the path pipeline distribution in field plots,get the terrain information through remote sensing technology and analyze the path and the amount of the water in the field plots by the ant colony algorithm according to the matter of the low generality in most parts in China.The result shows that the rules were put forward with shorter path,smaller cost and the most utilization of water eventually.It can be widely used in most areas which is lack of water and scientific technology. Key word: ant colony algorithm,optimization of water allocation, pheromone ,water-saving irrigation The ant colony algorithm was applied in saving data mining, network routing optimization, logistics distribution, and other issues as the development of the bionic engineering .The effect in agricultural irrigation has been known recently,therefore,how to design the Scientific and reasonable path and deployment plan is imperative.This article aimed to analyze several shorter path and distribution plans by the Positive feedback phenomenon of ant colony algorithm,by which the higher pheromone concentration the ants secret,the shorter path would be.According to the reasonable path,the aim to save water and increase production by using the Advanced science and technology can be reached.This research can provide new Ideas and methods for the DOI: 10.1051/ C © Owned by the authors, published by EDP Sciences, 201 / 0 0 ( 201 ) 201 conf Web of Conferences MATEC atec m , 0 0 6 6

affect the construction of (4).After the repeated cycle,the optimal solution will be put forward.
2 The simulation test for water-saving irrigation

Inspection of field
This paper selects some fields plots in Shuang Yashan as the coordinates.The specific coordinates are as followed.

Conclusion
This paper mainly takes out a method tending to get the most optimized result of only one path that can get to every point by using the ant colony algorithm.Meanwhile, the best effect of the way to water irrigation can be reached and the utilization of water is used in maximization.The method can solve the problems of serious water waste causing by uncertain path and low universalization of the deployment of canal water irrigation.It is worth to promote and employ especially in the areas where lack of water.
