摘　　要：[目的]TCN(列车通信网络)拓扑结构复杂而且对传输实时性要求较高,目前列车数据传输主要采用TRDP(列车实时数据协议)进行承载,但会存在网络时延不确定的问题,故研究采用TSN(时间敏感网络)保证数据传输的有界时延,来解决TCN面临的以上问题。[方法]提出了TTAM(一种TRDP与TSN自适应的方法),以实现TRDP与TSN的协议转换,保证列车数据在网络中传输的时间确定性。[结果及结论]通过搭建TSN测试台,对TSN网络功能及性能(IEEE 802.1 AS与IEEE 802.1 Qbv协议)进行测试,验证了TTAM在TSN技术应用中的有效性。[Objective]TCN(train communication networks)has complex topologies and requires high real-time transmission capabilities.Currently,train data transmission mainly relies on TRDP(train real-time data protocol)for carriage,while there are issues of network latency uncertainty.TSN is thus adopted to ensure bounded latency for data transmission,addressing the aforementioned issues faced by TCN.[Method]A method called TTAM(TRDP and TSN adaptive method)is proposed to achieve protocol conversion between TRDP and TSN,ensuring data transmission in the network.[Result&Conclusion]Through the establishment of a TSN testbed,the functionality and performance of TSN networks(IEEE 802.1 AS and IEEE 802.1 Qbv)are tested,validating the effectiveness of TTAM in TSN technology application.
