[0002] Oil film monitoring on water refers to the process of monitoring and identifying the oil film on the surface of water. Oil film on water refers to a thin layer of oily film formed on the surface of water, usually formed on the water surface by oil substances (such as petroleum, industrial wastewater, etc.). The purpose of oil film monitoring on water is to timely discover and identify the oil film phenomenon on the surface of water, so as to implement corresponding control and treatment measures to avoid pollution and damage to the water environment and ecosystem.

However, most of the existing non-contact sensors or detectors perform data detection and data collection on the vertical water surface. Since it is easy for some garbage and impurities to fall from other places on the water surface, which will cause a certain impact on the water surface, causing interference with the water surface detected by the detector, further resulting in uncertain factors in the data collected by the sensor, resulting in inaccuracy of the collected data, and making it difficult to better facilitate users to use.

The feature extraction and selection is to conduct a detailed analysis of the data transmitted from the data analysis and identification module, extract the key data information, and select the extracted feature information to reduce the number of The data modeling and evaluation is responsible for extracting features and selecting key information to model the oil film data. After data modeling, the modeling data is evaluated by cross-validation and ROC curve to ensure its performance and accuracy. The prediction and decision-making is responsible for predicting whether there is an oil film on the water surface and triggering the corresponding alarm based on the input oil film feature data. These units work together to provide accurate judgment and prediction of the oil film situation on the water by analyzing and identifying image data, and make corresponding decisions. The alarm and monitoring module transmits the data it obtains to the main server for storage and analysis. The oil leak detection The sensor transmits the detected data to the main server, and then the main server transmits the data caused by the detection to the alarm and monitoring module, the data analysis and identification module and the data storage and management module; the power supply is connected to the main server to provide it with power support, and the prediction and decision-making transmits some data that reaches the rated threshold and the data that causes the alarm to be activated back to the threshold setting and alarm triggering, and the actual data transmitted by the prediction and decision-making is recorded to achieve the optimization of subsequent threshold setting and alarm triggering. Later, the threshold setting and alarm triggering data are optimized to directly jump to the alarm, without the need to decide whether to issue an alarm through prediction and decision-making.

[0030] In the above embodiment, the data on the water surface can be collected through the installed oil leakage detection sensor, and then the obtained data can be transmitted to the main server.

[0035] In the above embodiment, the installed main body mechanism 1 can make it easier for the user to install and use the device, and can also make it easier to connect the ultraviolet fluorescence detection sensor 15 with the anti-interference mechanism 2. The installed anti-interference mechanism 2 can extend the interference column 26 downward, and the floating clamp 28 installed on the interference column 26 can suspend the interference column 26, thereby ensuring that the interference column 26 is in contact with the water surface and does not sink, thereby ensuring that the interference column 26 is in contact with the water surface, and then the interference column 26 can be used to isolate garbage and impurities on the water surface, preventing garbage on the water surface from staying on the vertical water surface of the ultraviolet fluorescence detection sensor 15.

The fixed clamping column 27 installed on the outer side of the bottom end of the interference column 26 can It is more convenient for users to install and disassemble the floating clip 28, so that it is more convenient for users to disassemble and clean the floating clip 28. The hook 29 installed on the floating clip 28 can better collect debris on the water surface to avoid affecting the water surface. The anti-interference mechanism 2 installed on the ultraviolet fluorescence detection sensor 15 can effectively isolate the debris on the water surface, thereby avoiding the previous situation in which the detection data is affected by the influence of debris on the water surface and the detection data accuracy is reduced. The accuracy of the detection data is further improved, and the detection effect of the detector is avoided from being blocked due to the influence of other objects, thereby making it more convenient for users to use.
