The security of this scenario was analyzed according to the analysis process of STPA method. Firstly, Unsafe Control Actions (UCAs) in this scenario were identified and Control Defects (CDs) were analyzed. After that, the corresponding Security Design Requirements (SDRs) were formulated according to the obtained control defects. Finally, the time automata network model of TSR sending scenario was established to verify SDRs. The result shows that: STPA method is suitable to discover the unsafe factors and safety hazards of train control system and take corresponding safety measures to prevent the occurrence of accidents.","PeriodicalId":443482,"journal":{"name":"2019 5th International Conference on Control Science and Systems Engineering (ICCSSE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130419088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dispose of the drone into a stable or semi-stable state. This paper takes the hook recovery UAV as an example, assigns the information source priority, defines the sensor failure criteria, and finally designs the sensor fault handling logic. The simulation test is carried out by semi-physical simulation. The results show that this method can switch the flight mode of the drone quickly and effectively when the sensor is faulty, and ensure the safe flight of the drone.","PeriodicalId":443482,"journal":{"name":"2019 5th International Conference on Control Science and Systems Engineering (ICCSSE)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126276750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
