摘要随着经济的高速发展，人们对交通的需求也越来越多，因此实时、精准的定位列车至关重要。在提高列车运营当中定位的精确度方面，利用新型列车组合的定位系统能够更好地帮助提高列车定位的精准性,也能够更好的保障列车运行的安全、高速，从而增加列车运营的安全性与运营效率。在人们对于列车交通的旺盛需求之下，一些老旧的定位手段已经不再适用于今天的轨道交通运营情况。所以说，以多种定位手段相互协作，共同对列车的运行进行实时定位的新型定位技术应运而生。在几种的定位手段相互协作之下，各个系统的优缺点则可以很好的相互补充。而控制台的工作人员据此便可以根据所反馈的信息规划出一种最优的列车运行路线，从而对于铁路线路的优化和运营成本的降低有着巨大的贡献。74909

本文将世界各国的当今的列车定位技术进行了比对综合，然后根据我们周边的现实情况因地制宜的为列车设计了一套符合我们现实所需的新型的组合定位系统。其运用的原理就是：在正常行驶的时候，优先使用GPS卫星定位系统对其进行精准定位。而当一些特殊情况，比如可见卫星不足4个，或者列车行驶到了复线区域而无法准确分辨出列车的具体位置，则使用RFID技术对系统进行辅助校正。

The System of New-style Train Fixed Positioning 

Abstract With the rapid development of economy, and the rapid growth of traffic demand, we need more and more real-time positioning of the train。 The use of new integrated train positioning system technology to improve the positioning accuracy in the running of the train and its accuracy is the better means, can better ensure the safety of train operation safety fast, increase of train operation safety and operation efficiency。 Under the strong demand of train traffic, some of the old positioning means is no longer suitable for today's rail traffic operation。 Therefore, a variety of positioning means to cooperate with each other, the operation of the train together to carry out real-time positioning of the new positioning technology came into being。 The advantages and disadvantages of each system can be complementary to each other under the cooperation of several positioning means。 The staff of the console can plan an optimal train operation route, which has a great contribution to the optimization of the railway line and the reduction of the cost of operation。

The background of the development of train positioning technology of current world each country comparison analysis, and according to the reality of our surrounding local designs a set to conform to our real needs new train integrated positioning system。 The principle of this system is: under normal circumstances, the use of GPS satellite positioning system is now more mature positioning of the train operation。 And when some special circumstances, such as visible satellites are less than four or the train traveling to a double track area and can not accurately distinguish train the specific location, using RFID technology for assisted correction of system。
