Embodiment Construction

[0038] A method and device for intelligent detection of light quality of a beacon light of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] As shown in the accompanying drawings, an intelligent detection method and device for the light quality of a beacon light of the present invention, aiming at the characteristics of on-site detection of a beacon light, adopts a long-distance imaging technology to realize remote acquisition of light signals. The remote acquisition system is composed of Kepler telescope (70mm diameter, 400mm focal length), 3:7 beam splitter lens, electronic observation eyepiece and optical fiber. The light signal from the beacon light is split through the 3:7 beam splitter lens. Among them, 70% of the light intensity is collected by the Kepler telescope collection system, the collected light signal is transmitted to the modular spectrometer through the optical fiber, and the light is split by the gra...

Abstract

The invention provides a method and a device for intelligently detecting the light quality of a beacon light, belonging to the technical field of beacon measurement. The method adopts long-distance imaging and tracking to track the position of the beacon light in real time and remotely acquire the light signal of the beacon light; The optical signal obtained remotely is separated by the wavelength of the optical signal of the beacon light by the modular spectrometer, and the characteristic wavelength of the beacon light to be measured is extracted from it; In the identification algorithm, a background identification algorithm is designed to eliminate interference, and conduct on-site detection and identification of the light quality of the beacon beacon. Realize the effective tracking of the light signals of fixed mobile beacons on land and mobile beacons at sea. Each device is integrated with a portable instrument, which is convenient to carry and improves the practicability of on-site detection. It can be easily carried to the operation site of the beacon light, and conduct accurate on-site inspection of the light quality of the beacon light, so as to grasp the operation of the beacon light in time.

Description

technical field [0001] The invention relates to the technical field of navigation mark measurement, in particular to an intelligent detection method and device for the light quality of a navigation mark lamp. Background technique [0002] At present, it is difficult to carry out on-site inspection on fixed navigation aids such as lighthouses, light stakes and other large and medium-sized navigation aids on marine buoys. Such navigation aids cannot scientifically and accurately detect and identify their light quality timing since they are installed. In the past, we could only rely on the inspector's naked eye observation and stopwatch timing, the method was rough and low in accuracy, and it was impossible to accurately and comprehensively grasp the actual working state of the light quality of the beacon light. To a large extent, it restricts the improvement of the efficiency of navigation aids. [0003] How to accurately detect the rhythm and flash period error of the light ...
