Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0026] See attached figure 1 , place the installation bracket 2 equipped with the silicon photovoltaic cell 4 and the two-dimensional moving mechanism 3 in the vacuum tank 1 where the irradiation uniformity measurement of the solar simulator 5 is required. The two-dimensional moving mechanism 3 is composed of an X-axis and a Y-axis installed on a rectangular guide rail. The X-axis motor controls the movement of the X-axis, and the Y-axis motor controls the movement of the Y-axis. A slider is insta...

Abstract

The invention discloses a solar simulator irradiation uniformity detection device in a spatial environment. The device comprises a solar simulator (5), wherein the solar simulator (5) is installed ina vacuum tank (1), a two-dimensional movement mechanism (3) is arranged on the solar simulator (5) in the irradiation direction, a silicon photocell (4) is installed on a sliding block of the two-dimensional movement mechanism (3), and the silicon photocell (4) and the two-dimensional movement mechanism (3) are connected with a controller (8). Compared with the prior art, the irradiation uniformity of the solar simulator can be measured just through one silicon photocell, and the situation that measurement results of different silicon photocells are different due to a temperature difference and other factors, and consequently irradiation uniformity measurement is not accurate is eliminated; and by the adoption of temperature control modules, the influence of a vacuum low-temperature environment on the silicon photocell and motors is eliminated.

Description

technical field [0001] The invention relates to a solar simulator irradiation uniformity detection device, in particular to an on-line monitoring device used under vacuum and low temperature. Background technique [0002] In the vacuum thermal test of spacecraft, heating sheets, heating rods, and heating cages were often used to simulate external heat flow in the past, and the solar simulator provides a new method for external heat flow simulation. The solar simulator has advantages beyond the reach of other external heat flow simulation methods in terms of uniformity, collimation and closeness to the solar spectrum. [0003] With the increasing requirements for the simulation accuracy of the heat flow outside the new type of spacecraft, the requirements for the non-uniformity of the solar simulator's irradiation are also getting higher and higher. At present, the requirements are usually better than ±5%. Therefore, in order to ensure the accuracy of the heat flow simulatio...
