摘要:随着人们对铁路速度的不断追求,中国铁路正在向高速铁路发展。本课题主要研究,在列车区间运行过程中,需要根据列车的占轨条件,确定通过信号机的显示,从而实现列车区间运行控制。本课题基于实验室条件,采用模拟列车运行与真实轨道电路设备相结合的方式,构建列车区间运行控制系统,上位机模拟列车过程,下位机根据模拟行车确定轨道电路的低频信息码,以及通过信号机的显示。课题研究重点在于解决上位机与现场信号设备之间的信息传递,即根据上位机发送的占轨信息,确定移频参数及通过信号机的显示,并采集现场信号设备状态,上传至上位监控计算机,实现对列车运行过程的监控。79590
Design of Train Interval Operation Signal Acquisition System
Abstract: With the constant pursuit of railway speed, China Railway is developing to high-speed railway。 The main research of this subject is that in the train section operation process, according to the trajectory of the train conditions, to determine the display through the signal, in order to achieve the train interval operation control。 Based on the laboratory conditions, the simulation of train operation and the real track circuit equipments are combined to construct the control system of train section operation。 The upper computer simulates the train running process, the lower computer determines the low frequency information code of the track circuit and signal display according to the simulation of the train operation。 The focus of the research is to solve the information transmission between the upper computer and the field signal equipments, that is, according to the information sent by the host computer to determine the frequency shift parameters and the display of the block signals, and collect the status of the scene signal equipment, upload to the host monitoring computer, to achieve the operation of the train monitoring。
Keywords: Train operation control; Signal Acquisition; Serial communication
