【摘要】：现如今,世界上的轨道交通的应用发生了翻天覆地的变化。在现在的铁路枢纽上,重载机车为了提高单次运载能力,通常情况下可以采用大功率的机车、增大列车轴重、采用相对较长的列车编组、在重载线路条件允许的情况下采用特殊的方法等措施,来提高牵引质量和运输能力,增大列车功率。重联机车分为内重联跟外重联。然而两种重联方式的内部网络均大同小异,基本一样。基于MVB总线的重联机车,将机车内的各个控制单元通过各个相关的网络节点连接为一个闭环网络,高效率、高准确度的传输,使得机车的安全系数大大提高。本文主要针对重联机车的主要电气设备组成、重联机车的MVB网络控制系统的硬件组成、MVB网络控制系统的可行性分析以及网络控制系统的实现等全方面的进行研究。在中联机车的主要电气设备的组成中介绍了关于受电弓、主变压器、牵引变流柜、制动控制单元、主断路器以及牵引电机等部件的功能;在MVB网络控制系统的硬件组成中主要介绍了模块化组成的相关硬件:网关模块(GW)、数字量输入模块(DI)、数字量输入输出模块(DIO)、模拟量输入输出模块(AIO)、智能显示单元(IDU),以及各单元的功能。在MVB网络控制系统的可行性分析中对MVB网络的数据传输、传输介质的选择以及原理、终端电阻在网络中的作用等方面的分析来证明MVB网络控制系统的可行性。在后面的网络控制系统的实现中,通过对各个部件组成的小单元进行功能介绍,介绍了WTB总线的功能,在最后主要介绍了MVB网络控制系统中的人机界面的实现。
[Abstract]:Nowadays, the application of rail transit in the world has changed dramatically. In the present railway hub, in order to improve the single load capacity of heavy haul locomotives, it is usually possible to use high-power locomotives, increase the axle load of trains, and adopt relatively long train marshalling. Special methods are adopted to improve the traction quality and transportation capacity and increase the train power under the condition of heavy haul line. Heavy online vehicle is divided into internal reconnection and external reconnection. However, the internal network of the two reconnection modes are similar, basically the same. Based on MVB bus, each control unit in locomotive is connected into a closed-loop network through each related network node, which makes the safety factor of locomotive greatly improved. This paper mainly focuses on the composition of the main electrical equipment of the heavy on-line vehicle, the hardware composition of the MVB network control system of the heavy on-line vehicle and the feasibility analysis of the MVB network control system and the realization of the network control system. The functions of pantograph, main transformer, traction converter, brake control unit, main circuit breaker and traction motor are introduced in the composition of main electrical equipment of Zhonglian locomotive. In the hardware composition of MVB network control system, this paper mainly introduces the related hardware of modularization: gateway module, digital input and output module, analog input and output module, AIOO module, intelligent display unit, digital input and output module, intelligent display unit, digital input and output module, and intelligent display unit. And the function of each unit. In the feasibility analysis of MVB network control system, the feasibility of MVB network control system is proved by analyzing the data transmission of MVB network, the choice and principle of transmission medium, and the function of terminal resistance in the network. In the implementation of the following network control system, the function of WTB bus is introduced by introducing the function of each unit. At last, the realization of man-machine interface in MVB network control system is mainly introduced.
