Embodiment Construction

[0024] The locomotive traction system control logic method includes the following contents:

[0025] 1) Divide the traction system control logic into six primary function sub-modules, namely: input information sub-module, self-check sub-module, command analysis sub-module, protection function sub-module, relay action sub-module, output sub-module; figure 1 shown;

[0026] 2) Use Simulink to model each functional sub-module; each functional sub-module reserves input and output ports, and both input and output ports are set in the form of a bus;

[0027] 3) Connect each functional sub-module through a bus: the output terminal of the input information sub-module is respectively connected to the input terminals of the self-test sub-module, command analysis sub-module, protection function sub-module, relay action sub-module, and output sub-module through the bus connection; the output terminals of the self-checking sub-module are respectively connected to the input terminals of th...

Abstract

The invention relates to a locomotive traction system, specifically to a locomotive traction system control logic method and device. Defects and problems of an existing locomotive traction control system are solved. The locomotive traction system control logic device consists of six primary functional sub modules which are correspondingly an input information sub module, a self-checking sub module, a command analysis sub module, a protection functional sub module, a relay action sub module and an output sub module; by using Simulink, each functional sub module is modeled; input and output ports are reserved in each functional sub module; the input and output ports are all arranged in the form of a bus; and each functional sub module is connected in the form of the bus. By using the locomotive traction system control logic method based on Simulink, the reliability of a traction system in the locomotive operation process is enhanced, each sub module is connected through a data bus, the development and testing work of a model can be performed by different development personnel, and the development cycle is shortened.

Description

technical field [0001] The invention relates to a locomotive traction system, in particular to a control logic method and device for the locomotive traction system. Background technique [0002] With the rapid development of rail transit, the reliability of the whole vehicle system during train operation has become a top priority. Existing locomotive traction control systems, especially electric locomotive traction control systems, use traditional code writing methods, which have the following defects and problems: [0003] 1) The reliability of the control logic of the traction system is not high; during operation, it may be difficult to describe the system control logic accurately and clearly by using the traditional code writing method, resulting in unstable operation of the system and the failure of the train to operate normally. [0004] 2) The control program generated by sub-function call mode has unclear control logic structure, cannot accurately describe the flow o...
