Problems solved by technology

However, it is difficult to conduct research on existing lines when increasing or decreasing stations, scaling the distance between stations, and changing the operating parameters of tram vehicles.
[0004] The pure software simulation method lacks intuition, and its road model simulation results for the operating lines of trams are only in the form of data, that is, only simulation reports can be generated. If the simulation report is based on existing research data, the limitations are even more limited. Big
At the same time, pure software simulation will inevitably be too idealized, and the error value during the driving process is not fully considered
[0005] In addition, the track of the tram has the characteristics of long lines and complex routes, and the direct simulation or only reduced scale simulation method has high requirements for the track lines and too high space requirements

Abstract

The invention discloses a method for monitoring a simulation operation of a tramcar. The method comprises the steps of converting a simulated line into a layer model composed of a model layer; constructing a physical model according to the constructed layer model; defining a simulation operation scheme of the tramcar to generate a tramcar simulation operation control instruction table; and controlling and simulating the operation of the tramcar according to the control instruction table, and collecting operation data.

Description

technical field [0001] The invention relates to the technical field of trams, in particular to a method for monitoring the simulated operation of trams. Background technique [0002] Modern trams have the characteristics of large passenger capacity, low pollution and energy consumption, short construction period and low cost. In order to solve urban traffic problems and build a modern urban public transport system, modern trams have been developed in some cities in my country. At this stage, many cities in my country are in the process of expanding tram lines, and it is often impossible to obtain the optimal solution through simple research on issues such as planning routes and setting up stations. [0003] At present, the existing methods are to conduct on-site investigations on existing lines and road networks, and use the relevant data of the existing lines collected by the existing dispatching system, and then analyze the parameters of the tram vehicle itself. However,...
