Embodiment 1

[0049] In order to realize the cascade control strategy, it is necessary to build a single-group train braking test platform consisting of the host computer software platform and cascade groups. figure 1 shown, including:

[0050] cascade marshalling;

[0051] PC software platform;

[0052] 1. Design of cascade marshalling

[0053] The cascade marshalling group is composed of an actuator controller, two brake actuators, a set of brake air circuit structure and a data acquisition module;

[0054] The input of the cascading marshalling is the control model transmitted by the upper computer software platform, and the output is the air pressure data collected by the data acquisition module, and the output of the cascading marshalling is transmitted to the upper computer software platform;

[0055] The actuator controller is connected to the upper computer software platform through a time-sensitive network (TSN) bus;

[0056] The actuator controller can adopt NI-9265 analog out...

Embodiment 2

[0084] In the process of cascade control, except for the first cascade, it is necessary to use the data collected by the acquisition module in the previous cascade test and combine the formula of braking theory to calculate the change formula of the air pressure at the front end of the next round of cascade train tubes. Get the control model for the next cascade trial. However, due to the limitations of the braking model theory, there are some errors between the calculation results of the formula and the actual results, especially after multiple cascades, the error accumulation cannot meet the accuracy requirements of the hardware-in-the-loop simulation test, so it is difficult to pass the cascade control. Strategies to carry out long-group braking tests.

[0085] In this embodiment 2, on the basis of the platform built in embodiment 1, further R&D and innovation are completed:

[0086] By establishing the cascade air pressure time series prediction neural network model, the ...

Abstract

The invention discloses an intelligent cascade test system for braking of a single-marshalling train, and belongs to the technical field of semi-physical simulation. The system is characterized in that in order to realize a cascade control strategy, a single-marshalling train brake test platform formed by cascade marshalling and an upper computer software platform are constructed, and the system comprises the following parts: 1, cascade marshalling: the cascade marshalling is formed by an actuator controller, two brake actuators, a set of brake gas circuit structure and a data acquisition module; and 2, the upper computer software platform, wherein the upper computer software platform is used for configuring air brake parameters, cascade marshalling number and basic test parameters of test conditions. According to the cascade cycle control strategy, the braking performance test of M marshalling trains can be completed through M cascade tests by using the existing single marshalling train braking test platform.

Description

technical field [0001] The invention belongs to the technical field of semi-physical simulation. [0002] technical background [0003] Heavy-duty transportation represents the advanced productivity in the field of railway freight transportation, is the pursuit goal and development direction of many countries, and has important strategic significance. After more than 20 years of development of heavy-duty transportation in my country, both the quality of traction and the scale of heavy-duty lines have been greatly improved, and it has made great contributions to ensuring the transportation of national key materials, especially coal transportation. In recent years, with the continuous development of heavy-duty transportation, while the railway freight volume has steadily increased, higher requirements have been put forward for the performance requirements of freight trains, especially the performance of the braking system of freight trains. [0004] Freight train braking syste...
