Software resetting and restarting method and system for heterogeneous control system of traction converter

Abstract

The invention discloses a software resetting and restarting method and system for a heterogeneous control system of a traction converter, a medium and equipment. The method comprises the steps of 1) reading data information of a real-time control panel in the heterogeneous control system of the traction converter; 2) judging whether the real-time control panel works abnormally or not according to the data information, and if the work is abnormal, entering the step 3); and (3) protecting the traction converter, and sending a reset command to the real-time control panel for resetting and restarting. The method has the advantages that the method is simple and reliable, hardware does not need to be modified, the abnormal control system can be restarted quickly, the train can recover to the normal operation state quickly, and the fault influence is reduced.

Description

technical field [0001] The invention relates to the technical field of converter control systems, in particular to a method and system for resetting and restarting the software of a traction converter heterogeneous control system. Background technique [0002] In the field of rail transit, the function of the traction converter control system is to control the operation of the train according to the instructions given by the control system. The control system consists of hardware and software. The hardware is mainly composed of control chips such as DSP, CPU, FPGA, power chip, etc. Its normal operation has certain requirements on the environment, such as the temperature range of -40°C to 80°C. The software is mainly composed of CPU timing control software, DSP real-time control software and so on. The control system may work abnormally during operation, and there may be two reasons: [0003] 1. The external environment, such as the complex electromagnetic environment and ...

Problems solved by technology

[0003] 1. The external environment, such as the complex electromagnetic environment and high temperature of the control system, may cause abnormal operation of the control system hardware due to electromagnetic interference;

[0004] 2. In terms of software, there may be abnormal operation of the control system due to array access out of bounds, memory exhaustion, deadlock, program runaway, etc.

[0007] 1. Need special hardware circuit;

[0008] 2. During the operation of the train, the entire traction converter is in a high-voltage working state. If no protection measures are taken, it will be directly protected by the hardware circuit, which may cause damage to the traction converter and cause serious failure effects.

[0009] Therefore, in the reset process, it is necessary to perform a series of timing protection first, and then perform a fault reset. FPGA chips are not suitable for timing protection control.
