摘 要
LonWorks列車監(jiān)控網(wǎng)絡(luò)是符合IEEE1473標(biāo)準(zhǔn)和我國TB規(guī)定的標(biāo)準(zhǔn)網(wǎng)絡(luò)形式之一。四方車輛研究所對其底層技術(shù)進(jìn)行了二次開發(fā)和國產(chǎn)化,形成了具有自主知識產(chǎn)權(quán)的系列產(chǎn)品。四方車輛研究所研制開發(fā)的Lonworks網(wǎng)絡(luò)列車監(jiān)控系統(tǒng),已先后應(yīng)用在武昌—北京的T79/80次列車上(已通過鄭州鐵路局鑒定)、蘭州動(dòng)車組上(16輛車)、京滬T22/21次高檔列車上(43輛車)。
空調(diào)列車在我國的迅速發(fā)展對我國當(dāng)前水平較低的傳統(tǒng)列車控制技術(shù)提出了挑戰(zhàn),應(yīng)用的需要使得發(fā)展我國自己的列車控制網(wǎng)絡(luò)成為當(dāng)務(wù)之急。在列車控制網(wǎng)絡(luò)中,列車總線、車輛總線是其中的主體部分,通過對整列車的控制的網(wǎng)絡(luò)化,實(shí)現(xiàn)動(dòng)車組中分散動(dòng)力的聯(lián)動(dòng)控制,確保列車上各系統(tǒng)的工作情況盡在掌握之中,并實(shí)現(xiàn)了信息共享。這是列車控制的發(fā)展趨勢。本課題正是針對空調(diào)車的控制系統(tǒng)展開研究的。
LONWORKS網(wǎng)絡(luò)控制技術(shù)是近年來迅速發(fā)展起來的現(xiàn)場總線控制技術(shù),在工業(yè)、樓宇、運(yùn)輸、能源等自動(dòng)化領(lǐng)域得到應(yīng)用。它集計(jì)算機(jī)、網(wǎng)絡(luò)、控制于一體,集成了ISO/OSI的全部七層協(xié)議,同時(shí)具有通信和控制功能,提供了34種常見的I/O控制對象,工作溫度范圍寬(-40℃~85℃),組網(wǎng)靈活,開放性好;所有這些都說明它能夠應(yīng)用到列車控制中。
空調(diào)高檔車上設(shè)有列車監(jiān)控網(wǎng)絡(luò),能夠自動(dòng)監(jiān)測車輛設(shè)備的各種參數(shù),以確保設(shè)備和車輛運(yùn)行安全以及乘車舒適性。。
本文提出了采用LONWORKS技術(shù)的列車控制網(wǎng)絡(luò),并針對我國目前的情況,對方案的實(shí)現(xiàn)進(jìn)行了詳細(xì)的論述。文中討論了節(jié)點(diǎn)的組合原則,分析了網(wǎng)絡(luò)的實(shí)時(shí)性,并重點(diǎn)論述了節(jié)點(diǎn)設(shè)計(jì)和組網(wǎng)設(shè)計(jì)。并設(shè)計(jì)出節(jié)點(diǎn)硬件電路。

Abstract
The rapid development of the EMU has challenged the low-leveled traditional train control technology in our country, which urges the development of our own train control networks. The train control network, which is mainly divided into train bus and vehicle bus, is used to synchronize the transmission system of the motor car, to gain the control and monitor the status of all the equipment in the train, and to share information with one another. Actually this has become the trend of the development of the train control. In this paper, the discussion is carried out based on the control system of EMU.
The LONWORKS technology, one of the many fieldbus technologies developed in recent years and available as an open standard to all manufacturers, now has been widely used in the automatic areas ranged from industry, building, transportation, to power system. It integrates computer, network and control into one technology and displaces proprietary centralized systems with open, highly distributed, interoperable systems. Neuron chip, whose network protocol has all 7 layers of the ISO/OSI reference model, has the abilities of both communication and application control, and provides 34 I/O object. The technology also provides versatile methods for building and managing the control networks.
In this paper, 3 solutions for the train control network are demonstrated based on the LONWORKS technology. And according to the actual situations in our country, the 3rd solution is further discussed in detail. The main principles for the definition of the different nodes in a network are given, and the characteristic of the real-time control is thoroughly analyzed. Furthermore, great emphasis has been put to discuss node design and network design. Meanwhile, this paper also analyzes the EMC of the system, for which some methods are given.
Finally, the paper provides certain results of the static tests and the dynamic test on-board the EMU, which in return proves the precedent design.
