Substation Design of Interval Operation Simulation System
Abstract: With the increasing requirements of people for the speed of railway transportation, the Chinese railway is developing in the direction of high-speed railways. This project is based on laboratory conditions, the combination of simulated train operation and real track circuit equipment are used to construct a Build train interval operation control system. The upper computer simulates the train operation process, and according to the simulation of the upper, the lower computer determines the low-frequency information code of the track circuit and the display of the block signals. The main research topic of this project is the design of the lower machine part. , During the process of simulating train section operation, the display of the signal machine is determined according to the conditions of the train occupying the track, so as to realize the function of train interval operation control. The research focus of the project is on the design of analog control box and the serial communication between the upper computer and the lower. That is, the lower computer determines the frequency shift parameters and the display through the signal machine according to the occupied track information sent by the upper computer, and collects the on-site signal device status. Upload to the upper monitoring computer to monitor the train operation process.
