Security And Reliability Design Of Antarctic Unattended Energy Communication Platform

China's first Antarctic scientific expedition support device has been successfully operated in Antarctica,providing energy,scientific expedition data storage,communication and remote monitoring and other guarantees for astronomical observations and other scientific expedition instruments and equipment in Antarctica,and achieving a zero breakthrough in the field of scientific expedition support platform research in China.Due to the short development time,lack of experience and the special environmental restrictions in Antarctica,the performance of the platform needs to be further improved.Based on the above reasons,this paper proposes an optimized design scheme for the unattended energy communication platform from the perspective of improving the reliability and security of the platform,so as to provide a more reliable guarantee for my country's polar scientific research.Firstly,the overall demand of the energy communication platform is analyzed.Based on the functional requirements and performance indicators of the platform and the research experience of the polar scientific research support platform at home and abroad,the overall planning and design of the system is carried out.The energy communication platform is divided into three parts: power generation system,on-site main control system and domestic monitoring system,and the overall security of the platform is designed.Next,the problems of the power generation system in the early energy communication platform are analyzed.In view of the disadvantages of the design schemes of the lubricating oil circuit and fuel oil circuit of the generator set,the hardware structure modification and the software algorithm design scheme are respectively proposed and tested,and the test results show that the trouble-free operation time of the oil circuit system after the modification has been greatly extended,and it has higher reliability.At the same time,the unit scheduling and fault switching control logic are designed to effectively judge and deal with the faults encountered during the operation of the generator set,ensure the secure and stable operation of the generator set and improve the reliability of the power generation system.Then,combining with the existing problems of the on-site main control system,the reliability and security of the system are improved respectively from the perspective of hardware and software.Through the design of the core control algorithm,the cabin temperature control,manual remote scheduling,and unit and load protection are realized.In order to make up for the defect that the controller itself cannot be reset through software restart when encountering an abnormality,a peripheral watchdog circuit is designed to allow the PLC to quickly restart and recover from the "crash" state and ensure the reliable operation of the main control system.The data communication between the main control system and the upper computer based on Socket connection is realized.Through the comparison of schemes,the MD5 algorithm is selected to verify the transmitted files,and the RC4 encryption algorithm is used to effectively protect the communication data security between the PLC and the upper computer.Finally,the operation reliability and communication security of the main control system are tested.Finally,in view of the problems of the monitoring interface in the early projects,the local interface and the remote monitoring interface of the energy communication platform are optimized and designed.The configuration software VISU+ is used to design the local monitoring interface,which is convenient for the experimenters to check the operating status of the equipment in the cabin under the state of the platform's closed cabin operation,so as to ensure the secure and reliable operation of the equipment.Windows system is selected as the platform to build the remote monitoring interface.Vue.js framework is used to develop the front-end display interface.The back-end code is developed based on the Spring Boot framework,and the My SQL database is used to store data interacting with the back-end.The functions of user login,real-time data query,historical data query,on-site acquisition image display,remote command interaction and so on have been realized in detail.Tests on each module show that the designed monitoring system can not only realize the remote monitoring and remote control of the platform,but also ensure the secure and reliable operation of the energy communication platform,achieving the expected goals of the project.
