Abstract: |
Water quality monitoring and evaluation are important practices for water resources management. And the major concerns are remote and low-cost information transmission technology and accurate water quality evaluation strategy. Taking these concerns into consideration, a remote monitoring and evaluation system based on wireless sensor networks (WSN) and LS-SVM method was designed in this paper. The ZigBee-WSN was used to transmit the water quality status information including dissolved oxygen, permanganate index, BOD5, ammonia nitrogen, total phosphorus and total nitrogen And the LS-SVM is selected as water quality level evaluation method. The test results show that the system has many advantages, such as economic, practical, with high communication reliability, fast and accurate evaluation accuracy.
