The light source 2 and the light sensor 3 are arranged on the housing 1 at intervals. The abrasion-resistant coating containing fluorescent powder is coated on the outer space of the continuous oil pipe 4, the abrasion-resistant coating is a fluorocarbon coating, a silicone coating or a polyester coating, preferably a fluorocarbon coating, the fluorocarbon coating is colorless and transparent, has excellent abrasion resistance and pollution resistance, can maintain stability in a high-temperature and high-pressure environment, and is suitable for being used on the continuous oil pipe 4. The fluorescent powder is silicate fluorescent powder or rare earth fluorescent powder, preferably rare earth fluorescent powder containing lutetium oxide, the content of the fluorescent powder in the wear-resistant paint is lower than 1%, the wear-resistant paint without adding the fluorescent powder is used as a base layer, a layer of wear-resistant paint containing the fluorescent powder is covered outside the base layer, two layers of wear-resistant paint without the fluorescent powder with thickness are coated between the wear-resistant paint containing the fluorescent powder and the continuous oil pipe 4, so that the adhesive force and weather resistance of the wear-resistant paint are not affected, the wear-resistant paint is prevented from easily falling off and cracking, and the width of the wear-resistant paint containing the fluorescent powder is 10-20 mm and does not affect the detection of an optical sensor.

The supplementary spraying adopts a cold spraying mode, so that the influence of the sintering of fluorescent powder on the luminous effect is avoided.
Referring to fig. 1 and 2, the casing 1 is a long cylindrical structure, and the length of the casing 1 is generally not less than 20cm, so as to avoid that the light sensor 3 confuses external light and light emitted by fluorescent powder, and identification errors are caused.
