真空熱試驗(yàn)測(cè)控儀器驅(qū)動(dòng)器通用化設(shè)計(jì)

General design of instrument drivers for the measurement and control system in vacuum thermal tests

摘要: 航天器真空熱試驗(yàn)中溫度的測(cè)量和外熱流的模擬使用到多種不同型號(hào)的測(cè)控儀器，這些儀器驅(qū)動(dòng)方式也大不相同,，這給測(cè)控系統(tǒng)應(yīng)用軟件的開發(fā)帶來(lái)很多不便,。文章基于VISA（虛擬儀器軟件結(jié)構(gòu)）標(biāo)準(zhǔn)針對(duì)目前使用的各種儀器編寫了通用的驅(qū)動(dòng)函數(shù)，并以動(dòng)態(tài)鏈接庫(kù)的形式進(jìn)行封裝,，可以供調(diào)用進(jìn)行二次開發(fā)，有利于儀器驅(qū)動(dòng)配置過(guò)程的簡(jiǎn)化和測(cè)控軟件的通用化設(shè)計(jì)。

Abstract: In the vacuum thermal tests for spacecraft, various kinds of programmable instrument are used, with different communication interfaces, bus types and driving modes, and it is often difficult to develop the application software for measurement and control with universality and inheritance. This paper develops universal instrument driver functions based on VISA, which are encapsulated with the dynamic link library technology to be easily called by users in secondary developments. These functions could simplify the configuration of the instrument driving process and the general design of the measurement and control software.
