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。
Abstracts:
［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.
