AI Technical Summary
In open water or under complex lighting conditions, natural light sources and artificial lighting interfere with the optical sensor's detection path, leading to a decrease in the signal-to-noise ratio of water quality monitoring signals, and the water flow state causes instability in the measurement signals.
A water environment monitoring system was designed, including a monitoring probe, a combined support, a shielding component, and a movable cover. The movable cover is used to open and close a closed cavity to isolate external light and water flow interference, thereby ensuring the stability of the monitoring area.
It effectively avoids interference from external light, improves the stability and signal-to-noise ratio of water quality monitoring signals, and ensures the reliability of monitoring signals.
