Multi-computer communication of spacecraft digital temperature measurement system

摘要: 溫度測量是真空熱試驗中一個重要的測量項目，數(shù)字測量技術(shù)是適應(yīng)真空熱試驗溫度測量需求多樣性的一項新的應(yīng)用技術(shù)，而實現(xiàn)多機通信則是數(shù)字測量系統(tǒng)的關(guān)鍵技術(shù)之一。文章建立了具有多種多機通信模式的真空熱試驗航天器溫度數(shù)字測量系統(tǒng)，闡述了不同多機通信模式的通信原理與協(xié)議，介紹了利用上位機管理軟件VB6.0實現(xiàn)串行通信以及對溫度數(shù)據(jù)進行管理的方法。

Abstract: The temperature measurement is one of the important tasks in the thermal balance and thermal vacuum test. The digital temperature measurement is a new technique, which can be used to diversified needs in thermal vacuum tests. The multi-computer communication is one of the key technologies of the temperature measurement system in the spacecraft thermal test. In this paper, a digital spacecraft temperature measurement system is established with various multi-computer communication modes. The related communication principles and protocols are discussed, with the host computer management software being used to achieve the serial communications and the management of the temperature data.
