Embodiment Construction
[0017] Organic substances such as oils will fluoresce under the irradiation of ultraviolet light. According to a large number of experiments, under the irradiation of ultraviolet light with a wavelength of 200nm-300nm, petroleum and other oily substances will produce fluorescence of 300nm-400nm, with a peak around 360nm, while water, road surface, cement and other substances will not produce the above-mentioned The phenomenon of reflected fluorescence.
[0018] Based on the above principles, the present invention provides a method for detecting oil pollutants, which uses 200nm-300nm ultraviolet light to irradiate the detection area at intervals; and obtains whether the detection area is oil spilled or not according to whether the reflected fluorescence of 300nm-400nm is received. judgment result.
[0019] The present invention also provides an oil pollutant detection sensor, which is arranged above the detection area without contact with the target to be measured, and uses an...

Abstract
The invention discloses a detection method and sensor for oil type pollutants. The sensor comprises an ultraviolet light generation device, a fluorescent light receiving device and a control unit, wherein the control unit is used for emitting ultraviolet light-triggered pulse signals at intervals, the ultraviolet light generation device is used for correspondingly emitting ultraviolet light to irradiate a detection area below the detector sensor for the oil type pollutants according to the ultraviolet light-triggered pulse signals, the fluorescent light receiving device is used for receiving fluorescent light reflected by the detection area and generating corresponding detection signals, and the control unit is used for reaching a judgment result whether the detection area has oil spill or not according to the detection signals. According to the sensor disclosed by the invention, an active light emitting way is adopted for detection, so that the reliable detection can be provided regardless of day and night; furthermore, as the sensor is not in contact with a detected target, the sensor can not be affected by biological dirt and fragments, and the workload of maintenance is greatly reduced; and moreover, serial digital signals can be outputted, and system integration and remote transmission can be facilitated.
Description
technical field [0001] The invention relates to a detection instrument, in particular to a detection method and a sensor for oil pollutants. Background technique [0002] Oil is one of the most important energy sources in the world at present. During the production, transportation, storage and use of oil, oil spill accidents occur from time to time, thus causing serious pollution to the ocean. With the development of the economy and the improvement of people's living standards, the problem of environmental pollution is becoming more and more serious. According to statistics, oil spills on water surface are one of the main factors causing marine environmental pollution, and the prevention and response speed of oil spills have attracted more and more attention. [0003] As we all know, real-time oil spill detection can enable relevant departments to respond in time, control pollution before it causes extensive damage to wildlife and the environment, and minimize pollution cau...
