Keyword微波湿度计 数据处理与系统控制 冗余设计
Abstract微波湿度计是风云三号卫星重要载荷之一,其中数据处理与系统控制单元是控制系统工作状态,数据采集和数据交换的核心部件,该单元的可靠性和安全性对微波湿度计至关重要.结合神舟四号多模态微波遥感器的研制经验,对冗余设计中通用的设计方案进行了分析和比较,详细介绍了风云三号卫星微波湿度计数据处理与系统控制所采用的冗余设计方案的选择依据,基本原理和特点.通过风云三号卫星微波湿度计的实际应用,该方案的可行性与可靠性得到了充分验证.
Other AbstractMicrow ave hum idity sounder is one of the impo rtant payloads in FY23 satellite.The microw ave humidity sounder consists of the pow er un it,the data p rocesso r and control unit and the receiver.The data processo r and con t ro l un it is the core of hum idity sounder,functions of it are con t ro lling system ,performing commands of FY23, samp ling data and t ran smit ting data. It is very impo rtant that this un it is reliab le and safe.According to the characterist ics of the m icrow ave hum idity sounder, there are two parts in the data p rocesso r and con t ro l un it.One part ismain, A no ther part is redundan t.One of the two part s mu st be unpow ered at anyt ime.We have compared th ree w ays of redundancy, JFET input operational amplif iers w ere u sed to be in terface in f inally.The characterist ics of the amp lif ier are low consumption,high inpu timpedance,output short-circu it protection and so on. In app licat ion of FY23, the reliab ility of this redundancy scheme has been p roven.
