基于VISA的程控直流電源控制技術在熱流模擬中的應用

Application of programmable DC power supply control based on VISA in heat flux simulations

  • 摘要: 程控直流電源在真空熱環(huán)境試驗中的作用是為紅外加熱器提供電流，滿足航天器外熱流模擬的需要。文章以LabVIEW軟件的VISA模塊為基礎，介紹了程控直流電源驅動控制器的設計方法和軟件編程，描述了電源驅動控制器在真空熱環(huán)境試驗中的應用。該程控直流電源控制系統(tǒng)界面友好，實現了模塊固化，提高了系統(tǒng)的可靠性。

     

    Abstract: Programmable DC power supply provides electrical current for infrared heater in vacuum thermal environment tests to simulate heat flux in spacecraft. This paper discusses the design of its control drivers based on VISA (virtual instrument software architecture) standard, including the design method and the software program, and their applications in vacuum thermal environment tests. This system is shown to be steady，reliable and easy to handle.
