摘　　要：时间触发以太网(TTE)的交换设备采用中央监视进行通信完整性检查,而对于具有网关的层次化TTE网络,需要在网关处设置系统级的通信完整性保证机制。面向通用的远程现场网络拓扑结构,设计了外部冗余物理链路和内部协议检查相结合的通信完整性检查网关,并构建半物理仿真平台,对设计实现进行了实验验证。仿真结果表明,该设计在充分利用设备级完整性检查功能的基础上,兼容了两端网络的交换式传输机制,有效地支持了系统级的故障隔离。Switching equipment of the Time-Triggered Ethernet adopts central monitoring system to check the integrity of communication. But for a hierarchical TTE network with gateway, a communication integrity security mechanism on system level should be realized at the gateway. Based on general topological structure, this paper presents a gateway with communication integrity check function, combining the external redundancy physical link with the internal protocol check. A semi-physical simulation platform is constructed to verify the design mentioned. The results indicate that based on the full use of the equipment-level integrity check function, this design is compatible with both ends of the network transmission and can support system- level fault isolation effectively.
