Diesel locomotive excitation controller dual-unit hot redundancy automatic switching system

Abstract

The invention provides a diesel locomotive excitation controller dual-unit hot redundancy automatic switching system, which comprises a first processing subsystem and a second processing subsystem. The first processing subsystem comprises a sending module for sending data to the second processing subsystem through a first serial port and a second serial port; and a fault detection module for detecting whether the system has a fault, and if so, enabling the working mode to change from a master control mode to a work mode change request mode, and modifying the unique identification number to be 0; and the second processing subsystem comprises a receiving module for receiving the data sent by the first processing subsystem through the serial port or an I / O port; a judging module for judging whether to switch the work mode of itself according to the work mode and the unique identification number in the data; and a feedback module for sending a feedback message to the first processing subsystem. The automatic switching system ensures continuous and stable work of the whole system, improves reliability of a diesel locomotive excitation controller and ensures safety of a diesel locomotive excitation system.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of electrical signal data processing, and in particular to a dual-machine thermal redundancy automatic switching system for excitation controllers of diesel locomotives. Background technique [0002] The main generator is the core equipment of the diesel locomotive, and the excitation control system, as an important part of the main generator, adjusts the excitation current of the main generator and controls the power output of the main generator, so the performance of the excitation control system is directly related to It affects the running stability of the main generator and traction motor. [0003] The reliability of the excitation controller for diesel locomotives needs to be improved in the prior art. Contents of the invention [0004] The invention provides a dual-machine thermal redundancy automatic switching system for an excitation controller of a diesel locomotive to over...
