| 摘 要： | 鉴于气囊差压数据对系留气球压力调节的至关重要性,提出了一种差压数据的余度设计方法。在分析差压传感器组成特点的基础上,采用硬件双余度差压传感器配置实现了气囊差压数据的三余度设计,并给出了基于互比监控的故障判定逻辑和故障处置方法,以较低的成本大幅提高了系留气球差压测量的容错能力。

Triplex Redundancy Design for Tethered Aerostat Differential Pressure Data |
| |
| Abstract: | Given the importance of differential pressure data for tethered aerostat pressure control system, a redundancy design method of differential pressure data is proposed. On the basis of analyzing the characteristics of the differential pressure sensors, dual redundant hardware using differential pressure sensor configuration has achieved triplex redundancy for measuring differential pressure, and fault diagnosis and decision are also given. Lower cost significantly increases fault tolerance for measuring differential pressure of tethered aerostat. |
