【摘要】：隨著鐵路信息技術(shù)的發(fā)展,我國(guó)已獨(dú)立自主開(kāi)發(fā)了包含鐵路控制科學(xué)和信號(hào)處理等關(guān)鍵技術(shù)和設(shè)備,并且逐步與世界鐵路系統(tǒng)標(biāo)準(zhǔn)接軌。1998年,鐵道部正式將TCN標(biāo)準(zhǔn)列我國(guó)的鐵路列車通信網(wǎng)絡(luò)的標(biāo)準(zhǔn)。 本文依托北京交通大學(xué)與青島四方車輛研究所開(kāi)展的企業(yè)橫向課題"UIC網(wǎng)關(guān)的設(shè)計(jì)與實(shí)現(xiàn)”,實(shí)現(xiàn)了多功能車輛總線MVB和絞線式列車總線WTB的實(shí)時(shí)協(xié)議(RTP協(xié)議)消息數(shù)據(jù)通信,并在原有協(xié)議的基礎(chǔ)上,增加了流量控制機(jī)制,保證服務(wù)質(zhì)量QoS,進(jìn)行的主要工作如下： (1)深入研究IEC61375-1標(biāo)準(zhǔn),劃分各功能模塊。根據(jù)實(shí)時(shí)協(xié)議RTP在OSI參考模型中對(duì)應(yīng)層的規(guī)定,抓住各個(gè)層的特點(diǎn)。為整個(gè)通信流程劃分模塊,設(shè)計(jì)相應(yīng)的數(shù)據(jù)結(jié)構(gòu)。在傳輸層實(shí)現(xiàn)的過(guò)程中,引入超時(shí)模塊,實(shí)現(xiàn)了單播和多播傳輸層狀態(tài)機(jī)制和狀態(tài)轉(zhuǎn)換,達(dá)到控制消息數(shù)據(jù)的目的。最后設(shè)計(jì)了打印模塊,方便調(diào)試和錯(cuò)誤修改。 (2)明確了模塊之間的接口,根據(jù)通信流程,確定調(diào)用關(guān)系。自頂向下依次驗(yàn)證程序各個(gè)模塊和接口函數(shù)。編寫測(cè)試樣例,集成各個(gè)模塊統(tǒng)一測(cè)試。設(shè)計(jì)用戶界面,方便操作。通過(guò)仿真實(shí)驗(yàn)后,完成系統(tǒng)集成,實(shí)現(xiàn)開(kāi)發(fā)板之間的真實(shí)通信,打印測(cè)試結(jié)果并分析。 (3)在RTP實(shí)時(shí)協(xié)議的基礎(chǔ)上,找出協(xié)議內(nèi)關(guān)于流量控制的不足,引入改進(jìn)的流量控制機(jī)制。測(cè)試中通過(guò)限制通信流速,達(dá)到分類處理數(shù)據(jù)包的目的。在列車通信網(wǎng)絡(luò)在保證服務(wù)質(zhì)量QoS方面做出嘗試。
[Abstract]:With the development of railway information technology, China has independently developed key technologies and equipment including railway control science and signal processing, and has gradually been in line with the world railway system standards. The Ministry of Railways formally listed the TCN standard as the standard of the railway train communication network in our country. Based on the enterprise horizontal project "Design and implementation of UIC Gateway", which is carried out by Beijing Jiaotong University and Qingdao Sifang vehicle Research Institute, this paper realizes the message data communication of MVB and WTB. On the basis of the original protocol, the flow control mechanism is added to ensure QoS. The main work is as follows: 1) deeply study IEC61375-1 standard, divide each function module. According to the rules of the corresponding layer in the OSI reference model of real-time protocol RTP, the characteristics of each layer are grasped. The corresponding data structure is designed for the module of the whole communication flow. In the process of transport layer implementation, the timeout module is introduced to realize the state mechanism and state conversion of unicast and multicast transport layer, so as to control the message data. Finally, a print module is designed to facilitate debugging and error modification. The interface between modules is defined, and the call relation is determined according to the communication flow. The top-down verifies each module and interface function of the program in turn. Write test sample, integrate each module unified test. Design user interface, convenient operation. After the simulation experiment, the system integration is completed, the real communication between the development boards is realized, the test results are printed and analyzed. On the basis of RTP real-time protocol, this paper finds out the deficiency of flow control in the protocol, and introduces an improved flow control mechanism. In the test, the data packet is classified and processed by limiting the communication flow rate. In the train communication network to ensure the quality of service (QoS) to make an attempt.
