基于区块链技术的航班协同运行保障系统架构设计

在民航领域的航班协同运行保障过程中,传统的信息共享方式存在数据外泄、记录篡改、数据难追溯、数据难监管、隐私难保护等问题,提出一种由机场、航空公司、空管以及地服公司协同参与的区块链架构——航班信息共享链架构。根据航班运行过程中的实际流程与需求,从层次结构、网络结构、访问事件监管机制与多通道设计四个方面设计该架构,进而形成一种新型航班协同运行保障系统架构。实验结果表明,该架构不仅能够满足航班协同运行保障系统需求,还减少了单节点存储容量,更好地实现了航班协同保障参与方之间的动态信息共享。

ARCHITECTURE DESIGN FOR FLIGHT COOPERATIVE OPERATION SUPPORT SYSTEM BASED ON BLOCKCHAIN TECHNOLOGY

In the process of flight cooperative operation support in the field of civil aviation,the traditional information sharing methods have problems such as data leakage,record tampering,difficult data tracing and supervision,and difficult privacy protection.This paper proposes a Blockchain architecture named flight information sharing chain architecture,which is coordinated by airports,airlines,air traffic control and ground service companies.According to the actual process and requirements of flight operation,the architecture was designed from four aspects:hierarchy,network structure,access event supervision and multi-channel design.Therefore,we formed a new flight cooperative operation support system architecture.The experimental results show that the proposed architecture can meet the needs of the flight cooperative operation support system,and also can reduce the single-node storage capacity.It can realize the dynamic information sharing among the participants of the flight coordination support party more effectively.
