Abstract

The invention relates to a railway vehicle general traction control platform and method. The traction control platform comprises a main processing unit, an inverter operation acquisition unit and a four-quadrant auxiliary operation acquisition unit connected to the main processor, a network communication unit and a general IO acquisition unit. The main processing unit comprises a main processor provided with a logic control module, and the network communication unit communicates with the main processor and the general IO acquisition unit. The inverter operation acquisition unit is provided with an analog quantity data acquisition module I, a traction inverter control module used for controlling the output voltage of an inverter, and an anti-skid and anti-idle control module used for controlling the torque of a traction motor. The four-quadrant auxiliary operation acquisition unit is provided with an analog quantity data acquisition module II, a four-quadrant rectification control module for controlling a phase shift angle and an auxiliary control module for controlling the output voltage and frequency of the inverter. The traction control and the auxiliary control are fused in theinvention, the operation and the collection are fused, the reliability is high, and the control process is simplified.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle control, and relates to rail vehicle traction control technology, in particular to a rail vehicle general traction control platform and method. Background technique [0002] Modern rail transit technology is characterized by high-speed passenger transport and heavy freight transport. The traction control system is the source of train power, and the technical difficulty is the greatest. The traction control unit is the main control unit of the traction control system, and its function is to realize the power control of the train traction and braking operation, and its importance is self-evident. The core technology of traction control has been monopolized by foreign rail transit giants for a long time, and domestic research on related technologies started relatively late. At present, some manufacturers have developed control equipment with independent intellectual property rights. The tractio...
