For the requirements of remote information management and mobile business , the microwave radio frequency identification ( rfid ) technology is studied in this dissertation , with the automatic train identification system of the national ministry of railroad as a background . the fundamentals associated with rfid system in the field of electromagnetics and communications are summarized and the technical essence is pointed out at the viewpoint of system design 为适应远程信息化网络管理和移动商务的需求,本文以我国铁道部铁路车号自动识别系统为研究背景,系统总结了射频识别( rfid )系统的电磁学基础和通信学原理,从系统的观点揭示rfid技术的实质,对微波rfid技术进行了深入的研究。
Maglev automatic train operation ( ato ) system is the keystone of maglev traffic technology . on the background of the maglev train of nudt and the world ' s fair route which is being constructed in kunming , this dissertation lays emphasis on the control algorithm , simulation of ato , and the experiments of determination of velocity and position ( dvp ) 磁浮列车自动驾驶( ato )系统是磁浮交通系统技术研究的关键技术之一,本文以国防科技大学试验线工程化样车和正在进行施工设计的昆明世博线为背景,着重研究了磁浮列车自动驾驶的控制算法,并进行了仿真分析和测速定位系统实验。
Secondly , on the basis of the basic structure of the brake control system , the theory of brake task programming is studied and analyzed thoroughly . on the condition of automatic train protection , the fixed block system and moving block system the brake task programming method is brought forward 其次,本文从制动控制系统的基本结构出发,对制动任务规划理论进行了详细的研究和分析,分别提出了在基于安全防护、固定闭塞和移动闭塞三种不同应用条件下的制动任务规划方法。
Refering to the platform screen door ( psd ) system applied in guangzhou metro line 1 & line 2 , this paper analyzes the supervision and control functions of the continued automatic train control ( atc ) system ( lzb ) , which is supported by the on - board and trackside equipment , and discusses the design of the interface between signal system and psd system from the aspects of safety and rationality 摘要基于广州地铁1 、 2号线屏蔽门系统工程,分析、介绍了由车载和轨旁设备支持实施的lzb连续自动列车控制系统的控制和监督功能,从安全、合理的角度综述了信号系统与屏蔽门系统之间的接口控制关系。
Automatic train protect system has several functions in train automatic protection ; decentralized automatic train control system has a remarkable ability in autonomous decentralization ; while advanced train administration system integrates modem communication technology , makes the train to detect the location and the approaching distance of other trains by using its own wireless communication 研究了轨道交通列车刹车系统能有效防止列车正面冲撞的原理;分析了轨道交通列车自动保护系统具有列车自动保护的诸多功能;论证了轨道交通列车分布式自动控制系统的功能结构与技术特点。
" this was due in large part to the substantial investment we have been making to enhance our productivity , by completing both refurbishment of our entire east rail fleet of trains and installation of an automatic train protection signalling system on the same line , " he said , adding both measures would increase east rail s passenger carrying capacity by 38 % 他说:有此佳绩,主要是因为我们致力提升生产力,并为此作出重大投资,包括全面翻新东铁车厢,以及在东铁安装列车自动保障信号系统。这两项措施使东铁的总载客能力提高了百分之三十八。
