【摘要】 铁路交通和铁路运输极大的便利了人们的出行和物资的运输。近些年来,铁路的迅猛发展,极大的沟通了城乡文化和物资交流,并促进了工农业生产的发展。进入21世纪,铁路运输在当代人们的社会生活和经济生活中的起着越来越重要的作用。中国铁路近十年已经实现了六次大面积的提速,且随着新型技术的发展,时速超过350KM的高铁也开始在国内大量兴建。由于火车的一次性客运量十分大,一旦出现事故,必然造成重大人员伤亡和无法挽回的损失。因此机车在铁路上运行的安全问题显得尤其重要,在铁路提速的同时,我们更要确保机车在铁路上的行驶安全。本文在已有的LKJ2000型列车运行监控记录装置基础下,研制设计出一种机车安全信息查询报警系统车载移动台。具体内容主要包括：车载移动台通过CAN转UART模块从监控装置LKJ2000采集机车行驶的相关信息,然后车载移动台通过GPRS无线通信模块将采集到的机车行驶信息无线传输到地面控制中心。同时,车载移动台对采集到的机车行驶信息进行判断,当发现机车处于非正常的行驶状况时,通过语音模块以语音的形式向司机发出报警。车载移动台的另一软件组成部分行车宝典存储有铁路安全规章制度以及相关行车资料,便于司机在驾驶时进行查询。此外,行车宝典从车载移动台获取机车的运行信息,并对获取的LKJ数据进行规整,自动生成司机报单,再通过无线网络发送至地面。本文所设计的车载移动台便于机车地面管理中心实时掌握所辖区域内的机车在铁路上的运行状况,利于地面管理中心及时合理的组织和调度机车。该车载移动台使得机车地面有关管理部门能够对机车的发生的突发状况做出及时处理和应对。同时,车载移动台的语音报警功能对机车司机的安全值乘提供了可靠的保障。该车载移动台适应现阶段我国铁路长交路运行和单司机值乘的现状,为各铁路机务段对在线机车的运行管理提供了可靠的科学依据,同时也提高了机务段的运作效率和管理水平。本文设计的车载移动台在几个月的实际应用中进行测试和改善,数据的采集和数据的无线传输等相关性能均实时可靠。更多还原

【Abstract】 Nowadays railway traffic and railway transport have greatly facilitated the travel of people and goods transport. In recent years, the rapid development of the railway has greatly connect the cultural and material exchanges between urban and rural,it also promotes the development of industrial and agricultural production.In twenty-first century, railway transport plays an increasingly important role in the social and economic life of contemporary people. The railway of china has achieved raising the speed during most area for six times.And with the development of new technologies, more and more high-speed rail with the speed more than350KM/h are already under construction. Because the train has a very large passenger capacity, it would caused a heavy casualties and irreparable loss once the accident happened. The security when locomotive running on the railway become particularly important. During the time when we raise the speed of locomotive, We need also to ensure the safety of locomotive traveling on the railway.This article designed a kind of train safety information inquiry and alarm system on vehicle terminal in the existing basis of LKJ2000locomotive running monitor and recording device. The specific contents of this article are made up of the following parts:First, the vehicle terminal collects the related running information and data of locomotive from the monitor device LKJ2000through the CAN to UART module.Then the vehicle terminal transmits the running information of locomotive which collected from LKJ2000to the ground control center through GPRS wireless communication module. Meanwhile the vehicle terminal analyses the related data and make a judgement according to the locomotive running data and alerts to the ground center when the vehicle terminal finds that the locomotive is in non-normal running state. Another software component of the vehicle terminal (the intelligent interaction center) stores the railway safety regulations and relevant traffic information, for ease of query by the driver in the course of driving. In addition,the intelligent interaction center can obtain locomotive running information from vehicle terminal,deal with the LKJ data from the course,and then generate a driver’s declaration automatically. After that it’ll send the declaration through wireless network to the center ground.The vehicle terminal designed in this paper can help the ground management center monitor the running state of locomotive on the railway which under the jurisdiction of the related ground management center. The vehicle terminal is beneficial to the ground management center to organize and dispatch the locomotive timely and rationally. The locomotive ground management department can make timely response to the unexpected situations occur on the locomotive through the vehicle terminal. Meanwhile, the voice alarming funcion of the vehicle terminal provides reliable guarantee for the locomotive’s running safety. It provides a scientific basis for locomotive management, helps the ground center master the locomotive manipulation of driver and improves the operation and management level of the locomotive depot efficiency.The vehicle terminal designed in this paper has been tested and improved in practical applications for several months. The related performance such as data collection and data wireless transmission are reliable.更多还原
