航天員出艙活動地面試驗(yàn)綜合復(fù)壓系統(tǒng)控制技術(shù)

The control technology of the synthetic recharge system for simulation tests on the ground of astronaut extravehicular activities

摘要: 為了驗(yàn)證人-艙-服系統(tǒng)的可靠性和安全性，必須在地面做充分的模擬試驗(yàn),。地面試驗(yàn)綜合復(fù)壓系統(tǒng)為航天員的生命安全提供了可靠的試驗(yàn)環(huán)境,。其中，測控系統(tǒng)采用的PCS7過程控制系統(tǒng)對關(guān)鍵環(huán)節(jié)均實(shí)現(xiàn)了熱備冗余,，滿足試驗(yàn)過程控制要求,，可靠地實(shí)現(xiàn)了綜合復(fù)壓系統(tǒng)的正常工作和緊急復(fù)壓自動控制流程，并圓滿地完成了人-艙-服聯(lián)合試驗(yàn),。

Abstract: To ensure the reliability and safety of the astronaut-spaceship-spacesuit system, a simulation test must be performed adequately on the ground. The synthetic recharge system (SRS) provides a reliable test environment for the astronaut activities. The new and highly reliable control system insures the test being carried out correctly. The PCS7 process control system is designed with all the crucial equipments being rendered backup, which makes sure for the SRS controlling flows being carried out reliably in both normal and abnormal states.
