Semi-physical simulation system and simulation method for microcomputer control system of diesel locomotive

Abstract

The invention relates to a simulation technology of a microcomputer control system of an internal combustion locomotive, in particular to a semi-physical simulation system and a simulation method of the microcomputer control system of the internal combustion locomotive. And the blank of lacking equipment for learning an EM2000 microcomputer control system at present is filled. The system comprises an EM2000 microcomputer control system, an industrial personal computer and a signal conditioning system, the industrial personal computer comprises an upper computer program, three communication interfaces and four data acquisition cards; the upper computer program comprises a display and operation layer, a logic control layer and a component layer; the signal conditioning system comprises a signal conditioning board, a CAN communication box, a constant current source module, a relay switch module and a single-chip microcomputer module. The signal conditioning board is used for conditioning the signal; the constant current source module, the relay switch module and the single-chip microcomputer module are respectively connected with the assembly layer. According to the invention, signals of an EM2000 microcomputer control system can be completely simulated, various working conditions can be realized, fault analysis can be carried out, fault phenomena of the system can be observed, and modularized hardware is easy to maintain.

Description

technical field [0001] The invention relates to a simulation technology based on a microcomputer control system of a diesel locomotive, in particular to a semi-physical simulation system and a simulation method of the microcomputer control system of a diesel locomotive. Background technique [0002] EM2000 microcomputer control system is one of the core components of diesel locomotives, mainly responsible for excitation function, logic function and display function. Most domestically produced diesel locomotives use this control system. [0003] At present, foreign manufacturers have withdrawn from the after-sales work of the EM2000 microcomputer control system, and are now undertaken by domestic OEMs. At present, there is no equipment and platform for systematically learning the EM2000 microcomputer control system, which cannot meet the application requirements of the EM2000 microcomputer control system. The user's learning of the EM2000 microcomputer control system mainly...

Problems solved by technology

However, for technical personnel who not only need to understand theory but also be familiar with practical application, book knowledge and watching video introductions are far from enough. They also need to have a deep understanding of locomotive operating principles, learn the information interaction between various modules, and combine book theory with practical operations. , in order to better serve the maintenance and after-sales work of the EM2000 microcomputer control system of diesel locomotives
