Rail transit signal system trackside device relay simulation method and system

Abstract

The invention discloses a rail transit signal system trackside device relay simulation method which comprises the following steps of acquiring the device interface relay logic, and abstracting the relay logic; forming a device interface relay configuration file, wherein a logic configuration file describes the action logic of each type of device interface relay, and the device configuration file configures the specific attributes of the devices in a specified station; representing the type and the sub-type of the same device in the logic configuration file and the device configuration file in a specified form; reading the logic configuration and device configuration files, matching logic for the device through the device type and the sub-type, and carrying out trackside device state and control logic simulation. The invention further discloses a rail transit signal system trackside device relay simulation system. According to the present invention, when the type or the control mode of the trackside device is changed, the simulation of acquisition control between a signal system software and the trackside device can be realized without modifying the simulation software, the development and test cost can be reduced, and the development and test efficiency is improved.

AI Technical Summary

Problems solved by technology

However, the labview software itself takes up more CPU resources, and secondly, when the logic or quantity of relays needs to be changed, the software needs to be re-modified.

[0005] 2. Logic simulation of a single device, through the object-oriented programming language, write the relay logic for each type of device, when you need to modify the logic or add devices, you need to re-modify the code, which is not flexible enough

[0006] The existing simulation system, whether it is Labview or object-oriented programming, realizes the simulation of the trackside equipment by writing the operation logic of the specified equipment in the software, which leads to the change of the type or control mode of the trackside equipment. Modify the code synchronously and recompile

Secondly, software developers generally do not understand the business logic of the signal system. Every time a functional module of a specified device is developed, the developer needs to understand the action logic of the device before converting it into software code.

Again, the action logic of each signal device is different, and each type of device must customize its own software module separately, and the modules cannot be reused

This leads to low development efficiency, and at the same time, there are situations such as repeated software revisions due to inconsistencies in understanding
