Non-contact water-surface oil acquisition sensor

Abstract

The invention discloses a non-contact water-surface oil acquisition sensor which comprises a light source, an emission lens, a receiving lens, a beam splitter, a receiving optical filter, a receiving detector, a controller and a signal processor, wherein a light beam emitted by the light source is projected on a detected water surface via the emission lens, part of water surface reflected light is received and converged by the receiving lens, converged light is projected on the beam splitter and is divided into two beams of light by the beam splitter, the two beams of light pass through the optical filter with different band passes and then are received by the receiving detector respectively, the receiving detector sends an optoelectronic signal to the signal processor, and the controller controls the light source and the receiving detector to work synchronously. Compared with the prior art, the non-contact water-surface oil acquisition sensor has the following benefits: the infrared differential detection way is adopted to effectively detect most oil varieties; the non-contact water-surface oil acquisition sensor can be adapted to a quiet or rippled water surface and has a larger detection distance range; in addition, ambient light does not interfere with detection and judgment; therefore, the antijamming capability is higher.

Description

technical field [0001] The invention relates to a non-contact water surface oil detection sensor, which belongs to the technical field of detection equipment, in particular to a sensor for detecting floating oil on the water surface. Background technique [0002] Oil spill on water surface is one of the main factors causing water environmental pollution. The implementation of reliable water surface oil monitoring can enable relevant departments to respond in a timely manner, control pollution before it causes extensive damage to the environment, and minimize the pollution caused by oil spills, which is of great significance to protecting the environment and benefiting mankind. The existing water surface oil monitoring sensors can be divided into two categories: contact type and non-contact type. The non-contact water surface oil sensor using the principle of optical detection has attracted much attention in recent years. The representative ones are the water surface oil sens...
