Abstract

The invention provides a trackside simulation method and a system. The trackside simulation method and the system specifically include: collecting actual state signals of physical devices including an annunciator and a turnout point switch, and performing analog collection of virtual state signals of a virtual device; updating an analog line operating state according to the actual state signals and the virtual state signals, including updating an access state and a turnout state in the analog line according to the actual state signals of the annunciator and the turnout point switches; outputting the analog line operating sate to a user through a graphical interface; outputting a device control signal according to the line operating state in combination with a user instruction; performing corresponding analog control operation on a mathematical model of the virtual device according to the device control signal; performing corresponding actual control operation on the physical device according to the device control signal, including controlling a display state of the annunciator and a positive and reverse position state of the turnout according to the device control signal. The trackside simulation method and the system can realize semi-physical simulation of a trackside system, thereby facilitating testing of a device and training of operating personnel.

Description

technical field [0001] The invention relates to the field of transportation, in particular to a trackside simulation method and system. Background technique [0002] The domestic CBTC system (Communication Based Train Control System, train control system based on wireless communication) is an automatic train control system, based on the principle of moving block train intervals, to realize the control of trains, mainly applicable to subway and light rail systems. The system control level in the domestic CBTC system supports a variety of control modes, from inter-station block based on semi-automatic block to point control level based on fixed block principle and transponder, to the use of high-precision train positioning, train-ground continuous two-way communication CBTC control level. It can cover the operation of different levels of automation under the same signal system, the mixed operation of different types of trains and the application of multiple driving modes, and...
