Multi-mode power control method

Abstract

A multi-mode power supply control method belongs to the technical field of power supply control. The problem of how to provide a power control method capable of realizing precise temperature control with multiple control modes is solved. In the multi-mode power supply control method of the present invention, first connect the device, then create a power configuration file in the computer, set the power configuration and save it, then read the power configuration file, and judge whether the file format of the power configuration file is correct, if not, Change the power supply configuration file and re-judge the file format. If it is correct, initialize the program-controlled power supply, and judge whether the control mode of the program-controlled power supply is the power supply open-loop control mode, the power switch control mode or the power supply PID control mode, and finally control according to the respective control processes of the control modes. until the end of power control. The control method has a variety of control modes, and can flexibly control the output power of the heating device according to the needs, so as to obtain the required heat flow or temperature, and has broad application prospects in the ground environment test of aerospace products.

Description

technical field [0001] The invention belongs to the technical field of power supply control, in particular to a multi-mode power supply control method, and is especially suitable for power supply control in ground environment tests of aerospace products. Background technique [0002] The purpose of the ground environment test of aerospace products is to simulate various environments experienced by aerospace products in space and their effects in ground test equipment to test whether aerospace products can withstand the test of these environments and work normally. The ground environmental test of aerospace products is an important link in the development process of aerospace products, in which the accuracy of heat flow simulation and temperature control has an important impact on the reliability and validity of thermal test results. There are many forms of heat flow simulation and temperature control. Among them, constant heat flow simulation and constant temperature control...

Problems solved by technology

However, in the existing technology, the power control mode of the ground environment test of aerospace products can only realize a single function, and the application is limited

[0003] In addition, for some aerospace products with stricter temperature requirements, such as space optical remote sensors, precise temperature control must be achieved in ground environmental tests. The conventional closed-loop control mode has a control accuracy of ±1°C, and it is difficult to achieve precise temperature control of ±0.1°C. , therefore, a power control mode with higher temperature control accuracy is required
