A ship cabin light environment evaluation method and system based on an extension method

Abstract

The invention relates to a ship cabin light environment evaluation method and system based on an extension method, a light environment evaluation result is calculated through an evaluation index, andthe method comprises the following steps: setting the evaluation index; Establishing an extension method evaluation mechanism based on the evaluation index; Calculating and outputting evaluation results. According to the method, a plurality of subjective evaluation factors are integrated to serve as indexes, a comprehensive evaluation result is calculated through an extension set and a data association function relation, and scientific and objective evaluation is conducted on the ship cabin artificial lighting light environment through the system so as to assist in achieving maintenance or improvement of the ship cabin artificial lighting light environment.

Description

technical field [0001] The invention relates to the technical field of artificial lighting, in particular to a method and system for evaluating the light environment of a ship cabin based on an extenics method. Background technique [0002] Ship cabin lighting lacks sunlight and relies entirely on artificial light sources, so the quality of the cabin artificial lighting light environment has attracted much attention. The cabin is the living space for the staff. With the continuous improvement of the level of equipment and technology, the working and living environment of the staff has become more and more important to the lighting environment of the cabin. Various manipulation operations and tasks have a great impact. This is because more than 80% of the information in human life comes from vision. If the staff work and live in an environment with unreasonable illumination for a long time, it will cause vision loss and psychological discomfort. Reduce labor productivity, ca...

Problems solved by technology

[0009] In the existing technology, it is generally judged whether the light environment is reasonable by analyzing the data, and then corresponding improvement measures are taken; while the commonly used comprehensive evaluation methods mainly include weighted average method, analytic hierarchy process, fuzzy comprehensive evaluation method, etc., but there are certain limitations. Insufficient, the analytic hierarchy process has the disadvantages of strong dependence on subjective judgment, inability to express uncertainty and large amount of calculation; the fuzzy comprehensive evaluation method may obtain false superior solutions, and the sensitivity is low when there are many evaluation factors.

[0010] The invention patent application with the application number "CN201610977865.2" discloses a method for evaluating the health of an indoor light environment, which includes the following steps: Step 1: Measure the illuminance value of the light environment and perform dimensionless processing on the illuminance value to obtain the illuminance level D ; Step 2: Measure the brightness of the light environment and perform dimensionless processing on the brightness value to obtain the brightness level F; Step 3: Calculate the light satisfaction level SL according to the measured illuminance value; Step 4: Calculate the natural lighting rate C of the light environment and Dimensionless processing to obtain the natural lighting rate level A; Step 5: Calculate the uncomfortable glare index UGR and obtain the uncomfortable glare level B through dimensionless processing; Step 6: According to the illuminance level D, brightness level F, light satisfaction SL, natural The values ​​and weights of the five indicators, the daylighting rate level A and the uncomfortable glare level B, are used to comprehensively evaluate the indoor light environment by using the analytic hierarchy process, so as to fill the gap in the comprehensive evaluation model of the indoor light environment; For spaces illuminated by light sources, there is currently no effective evaluation model for the evaluation of light environment quality in spaces that rely entirely on artificial lighting
