DONGFENG 6 Locomotive Micro-computer System Distributed Simulation Trial Platform Investigation

Using 9 sets 386 micro-computers as actual diesel engine, exciter alternator, propulsion alternator and 6 sets traction motors of DONGFENG 6 locomotive electric transmission system respectively, develop DONGFENG 6 Locomotive Micro-computer System Distributed Simulation Trial Platform. Each set solves its mathematical model by digital simulation, analogous value can be got form the AD/DA links between sets. A 386 mainframe monitor communicates with every set by serial ports, and monitoring their running states, recording their simulating curves and data. This kind of distributed construction and data processing as well as signal transmission with compound digital and analogous simulation simulates more visually the actual locomotive electric transmission system, ensuring the information transmitting with high speed as well as avoiding synchronous problem of multi-computer links with good flexibility and generalization. The mathematical modals use nonlinear model conforming to the reality with fine precision. The dynamic performance can be known well by using this simulation trial platform, cut down manpower and material resources on trial of locomotive, improve manufacture efficiency of controller design.
