Problems solved by technology

[0003] 1. There is no precise temperature control device to control the surface temperature of the boss model, and the inaccurate measurement of temperature will bring large errors to the calculation results;
[0004] 2. The test conditions are greatly affected by the outside world, and the test must be carried out in a relatively open and unobstructed open space with good light and a long duration

Embodiment Construction

[0042] Specific embodiments of the present invention will be discussed in detail below in conjunction with the accompanying drawings.

[0043] The boss model measurement scheme of the present invention needs to adopt two kinds of data, one is to detect the transient temperature field of the boss model in the external convection environment and radiation environment in real time, this part is mainly completed by the thermocouple and the thermal imager; the second is Detect changes in meteorological attributes during the test, such as the radiation intensity of the sun and the environment, wind speed, wind direction, air temperature, etc. This part is completed by the cooperation of the anemometer meteorological instrument and the radiation meteorological instrument. The test site is set in a relatively open and unsheltered open space, which can receive better light from 9:30 am to 3:30 pm. The test site and test equipment are as follows: figure 2 shown.

Abstract

The invention relates to a special boss model. Corresponding temperature data and meteorological environment data are acquired through a wind speed weather instrument and a temperature acquisition unit. An overdetermined equation set about solar irradiation parameters is constructed from temperature balance equations of different surfaces of the boss, and an inversion result of the solar irradiation intensity is obtained by solving the optimal solution of the overdetermined equation set under the l1 norm meaning and used for supporting calculation of the ship infrared radiation intensity in the marine environment.

Description

technical field [0001] The invention provides a measurement scheme of a boss model, which is used for the inversion calculation and verification of the solar radiation intensity, and especially relates to the measurement of the infrared characteristics of the ship. Background technique [0002] Due to the rapid changes in the working conditions of the sea environment, the solar radiation intensity, wind speed, wind direction, and ambient temperature will have instantaneous changes, and the ship will turn, accelerate and decelerate when sailing at sea, these factors will cause the temperature field on the surface of the ship It is in an unsteady state of instantaneous change, which causes a large error in the calculation of the infrared characteristics of the ship. The wind speed, wind direction and ambient temperature can be measured more accurately by the existing instruments and equipment on the ship. If a solar irradiance meter is installed at the corresponding position o...
