Method and device for regulating and controlling the temperature of radiation block in vacuum environment

Abstract

The invention relates to a method and device for regulating and controlling the temperature of a radiation block in a vacuum environment, a computer storage medium and a background radiation simulator. The method includes the steps that a temperature sensor measures a real-time temperature signal of a radiation plate, and a temperature control module acquires the real-time temperature signal measured by the temperature sensor, compares the real-time temperature signal with a temperature control target range and circularly executes temperature judgment according to a fixed cycle to generate a power supply control instruction and a liquid nitrogen control instruction; a power supply controller receives the power supply control instruction of the temperature control module, completes power supply voltage control and outputs power supply voltage to a heating film; a liquid nitrogen controller receives the liquid nitrogen control instruction of the temperature control module, completes liquid nitrogen supply control, and outputs liquid nitrogen of a liquid nitrogen source to a heat sink; the heating film heats the radiation plate according to the power supply voltage; the heat sink cools a lining plate, the heating film and the radiation plate according to the input amount of the liquid nitrogen. According to the method and device for regulating and controlling the temperature of the radiation block in the vacuum environment, the computer storage medium and the background radiation simulator, a closed-loop control channel is utilized, and a wide-range temperature regulation andcontrol effect in the vacuum environment is achieved.

Description

technical field [0001] The invention relates to a temperature control method in a vacuum environment, in particular to a method, a device, a computer storage medium and a background radiation simulator for a radiation block temperature control method in a vacuum environment. Background technique [0002] In the space environment simulation test, the existing background radiation simulators usually control the temperature in one direction, the temperature control range is small, and the simulation device is relatively rough. After the radiation simulation is over, it can only be cooled naturally. This process will still generate ineffective heat flow, and the effect of the heat flow will be reflected in the test data. Therefore, the data after the test needs to be processed in the follow-up, and the factors affecting the stripping error are increased. The difficulty of data processing. [0003] Therefore, in the space environment simulation test system, how to quickly and re...
