【摘要】 列车监控系统是保证列车安全和进行事故分析的重要设备,对列车监控系统进行仿真和应用研究,可为监控系统提供测试和应用实验平台;可应用与培训教学;也可应用于列车驾驶仿真器等,具有一定的理论意义和较好的使用价值。鉴于LKJ2000型列车运行监控记录装置已经在我国批量使用,所以,我们研制了一种模拟机车信号的模拟接口电路,用以模拟产生机车速度信号、工况信号等,可以用来离线检测LKJ2000型列车运行监控记录装置,同时,也可以用于机车仿真器。接下去对地面信号种类及其特点做出详细分析,提出了两种移频信号发生器的实现方法,并提出了对地面信号的识别方法,其中分析了目前使用较多的3种制式地面信号的过绝缘节判别方法,同时分析了3种制式信号的制式区分方法。然后对监控装置的速度控制模式进行了研究,同时用PC机研制一个列车监控装置的全数字仿真器,由于造价便宜且使用方便,可以方便的应用于教学,也可以连接于机车仿真器,用作教学及试验。将来我们还要继续深入的研究列车监控系统,并且积极发展它的应用,对我国铁路事业的进步做出一份贡献。更多还原

【Abstract】 Locomotive monitor system is an equipment to protect the safety of the locomotive, could research and analsys the accident. The application and research can bring a platform for detecting and simulating of the monitor system. For LKJ2000 monitor equipment has been mainly used in our country, so, in this paper, we want to research a simulation of interface circuit, aimed to simulate the signal from the locomotive, such as locomotive’s speed signal, work condition of the locomotive. And the interface circuit can be used to detect the LKJ2000 monitor equipment, to check whether LKJ2000 monitor equipment can normally work or not, and can be used for education; so, can be used for locomotive simulator. Then we will research the type and feature of the ground signals, and bring up two types of Frequency-shift Modulated Signal’s generator, at the same time, we will research the identify method of the ground signals. And then we will research the speed-control mode of the LKJ2000 monitor equipment, At the same time, we have another plan, research a digital simulator by personal computer, it will include digital signal generator of locomotive, and a digital monitor equipment, for it will be cheap and can easily work, could be easily used for education, and can be connected to the locomotive simulator for experiment and education. Further more, we will research the locomotive monitor system deeply, and improve the application, to contribute our country.更多还原
