Review on Human-machine Interaction Safety Analysis of Spacecraft
After the improvement of the spacecraft hardware and software reliability,the HMI(human-machine interaction)error has become a weak point that affects spacecraft safety.In this paper,the necessity and importance of developing HMI safety analysis are elaborated.The cha-racteristics of HMI safety in ground operations,teleoperations and in-orbit operations are ana-lyzed.On this basis,the HMI safety analysis of spacecraft is analyzed from three aspects of HRA(human reliability analysis)method,system safety analysis method involving HRA,human er-ror data collection.Some shortcomings,such as imperfect HMI methods for the scenario of multi-person,long-duration,extravehicular mission and human error data deficiency,are also proposed.Finally,the technology development suggestions are proposed,for example,analyzing the HMI safety analysis methods which are appropriate for Chinese spacecraft,improving the hu-man error data collection and procession,and developing instrumental software tools.
