Research on water quality assessment method based on multi-class support vector machines

It has been a more complex problem for water quality assessment. And its aim is to well and truly evaluate its degree of pollution for bodies of water, which will be easy to provide some principled projects and criterions for water resource´s protection and their integration application. So, it has been widely applied into water quality assessment. SVM and directed acyclic graph support vector machine (DAGSVM) are paid much attention in this paper. A water quality assessment method based on DAGSVM is put forward. The test results show that the method proposed in this paper has an excellent performance on correct ratio. Besides, a wireless water quality monitoring system is designed and developed. The system can realize the acquisition of the water parameters, and the acquisition information timely and low cost transmission by GPRS (general packet radio service, GPRS). The developed system can store and display the water quality parameters from the monitoring spots in real time. Combining the wireless communication technology with the monitoring technology, the designed and developed system can greatly improve the real-time and continuity for the water quality´s monitoring and assessment.
