- 摘要:
- 在空管系统的实际工作中,需要从生产系统的隔离网络中提取运行数据到其他系统,用于满足生产运行管理、数据统计、安全监督等工作需求。现有的网闸、光闸等网络间单向传输设备存在成本高、传输可靠性不足的问题,不能完全满足空管系统实际工作需要。为此设计并实现了基于UART接口双单向通信的跨网络数据传输设备及相应的传输协议,在单向数据通信通道的基础上增加数据校验的反馈通道,在保证网络隔离的同时,降低了设备部署成本,提高了数据传输的可靠性,可用于解决生产设备间的数据共享问题。
- Abstract:
- In the practical operation of air traffic management(ATM), some production systems, such as Air Traffic Control, are isolated from other systems for network security reasons. However, data from these above-mentioned production systems are needed for some low network security level systems to fulfill the needs of production operation, data statistics, safety supervision. For network security reasons, network isolation gateways are applied between different network security level systems. But there are some problems when these above-mentioned devices are in application, such as high costs and low efficiency of data transmission, which cannot fully meet the requirements of ATM. To solve the problems, this paper designs and implements a cross-network data transmission device and corresponding transmission protocol based on UART interface. By adding a feedback channel for data verification to the unidirectional data communication channel, which ensures network isolation while reducing device deployment costs and improving data transmission reliability, can be a solution for data sharing problems between different network security level networks or systems.
