Electric locomotive traction controller state feedback device and system

Abstract

The invention provides an electric locomotive traction controller state feedback device and a system. the electric locomotive traction controller state feedback device comprises a signal converter and a signal processor, wherein the signal converter comprises at least two ways of signal input ends and one way of signal output end; the at least two ways of signal input ends is connected with a traction converter cabinet feedback device of the electric locomotive; the one way of signal output end is connected with the signal processor; the signal converter is used for converting digital state feedback signals inputted by the at least two ways of signal input ends respectively to a way of analog output signals, and the way of analog output signals is outputted to the signal processor; and the signal processor is used for carrying out signal analysis on the way of analog output signals to obtain digital state feedback signals. According to the electric locomotive traction controller state feedback device provided by the invention, the resource utilization rate of a core control chip can be enhanced.

Description

technical field [0001] The invention relates to the technical field of railway locomotives, in particular to a state feedback device and system for traction controllers of electric locomotives. Background technique [0002] Rail transit has always been the main development direction in the field of transportation. Especially in recent years, the development of electric locomotives such as subways, bullet trains, and high-speed rails has become faster and faster, and the demand is huge. In the control system of the electric locomotive, the traction control unit is used to realize the electric traction and braking control of the electric locomotive, and make corresponding control adjustments according to the state feedback signal transmitted by the feedback device of the traction converter cabinet of the electric locomotive. [0003] At present, the state feedback circuit of the electric locomotive traction control unit adopts the general input pin of the core processing chip ...

AI Technical Summary

Problems solved by technology

[0004] However, with the continuous development and innovation of electric locomotives, from the perspective of comfort and functional design of electric locomotives, the number of state feedback signals of traction control units of electric locomotives is increasing. If the existing signal feedback method is adopted, due to The general-purpose input pin resources of the core processing chip are limited, which will not be able to meet the quantity requirements of the state feedback signal
