摘要:

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。

关键词: 微波湿度计数据处理与系统控制冗余设计    
Abstract:

Microwave humidity sounder is one of the important payloads in FY-3 satellite. The microwave humidity sounder consists of the power unit, the data processor and control unit and the receiver. The data processor and control unit is the core of humidity sounder, functions of it are controlling system,
performing commands of FY-3, sampling data and transmitting data. It is very important that this unit is reliable and safe. According to the characteristics of the microwave humidity sounder, there are two parts in the data processor and control unit. One part is main, Another part is redundant. One of the two parts must be un-powered at anytime. We have compared three ways of redundancy, JFET-input operational amplifiers were used to be interface in finally. The characteristics of the amplifier are low consumption, high input impedance, output short-circuit protection and so on. In application of FY-3, the reliability of this redundancy scheme has been proven.

Key words: Microwave humidity sounder    Data processing and system managing    Redundancy scheme
