Automatic monitoring system for river water quality

　　Automatic monitoring system for river water qualityTraditional data report forms are abstract, making it difficult for managers to quickly identify water quality anomalies in blind spots. By generating a comprehensive water quality heatmap and indicator change curve, the numerical values of dissolved oxygen, ammonia nitrogen, and other indicators can be converted into visual graphics: the heatmap can intuitively present the gradient of water quality indicators in different areas (such as the high red ammonia nitrogen concentration in a blind spot pond mouth of a breeding farm), and the change curve can compare the differences in indicator fluctuations between the core area and the blind spot.Automatic monitoring system for river water quality
