| With the rapid development of the network,the level of social informatization is constantly improving,resulting in the rail transit train network needs to be able to carry more data transmission.What’s more,due to the higher requirements of network bandwidth,rail transit train communication is facing a huge change.The Train Real-time Data Protocol based on Ethernet has been widely studied due to its high reliability and high real-time performance.This article mainly implements TRDP protocol based on Linux system,and researches and implements the train gate control software update system based on TRDP.Firstly,,the background and development of TRDP and train gate control update system are introduced.Then it introduces the basic communication protocols,including Ethernet frame protocol,IP protocol,UDP protocol,etc.,and focuses on the train real-time data protocol TRDP,laying a theoretical foundation for the research and implementation of the train gate control update system.Then,according to the needs of related companies to the upgrade the gating system,the overall architecture of the train gate update system based on TRDP is proposed,including the TRDP moudle,processing module and control management module,and the software architecture of the TRDP moudle,processing module and control management module is described in detail.Then,the concrete design steps and realization methods of the software function unit of the TRDP moudle,processing module and control management module are given.Finally,the software update system of train gate control is tested and improved in related gate control unit.Tests show that the TRDP implemented in this article complies with the IEC 61375 standard specifications,and the train gate control software update system based on TRDP can meet the system indicators proposed by the corresponding company and complete the requirements for gate control software upgrade.It’s an important step for TRDP applications. |
