Application of fuzzy and binary algorithm to regulation of load in locomotive load test

The purpose of locomotive load test is to examine and adjust the capability of locomotive often in its non-driving state, and it is a kind of important standard and means to estimate the quality of repairing locomotive in railway locomotive depot. There are two ways of load test at present. One is the water-resistor load test, the other is the dry resistor load test. Because the dry resistor-load test means does not pollute the environment and needs area less, its developing foreground is immense. To solve the difficulty that the current cannot be freely regulated continuously, for the first time, the model of weightier resistor network in digital circuit is applied to the locomotive dry resistor-load test system, which solves the problem of dry resistor-load test theoretically. It is proved by theory and test that the precision of dry resistor means can meet the request of locomotives constant power load test and reach the standard of water-resistor, so it can serve the application of the dry resistor-load test system. During the locomotive load test, the load of locomotive may be regulated so that the locomotive can be adapted run on all kinds of actual work state. According to the characteristic of weightier resistor, the control arithmetic, which is made up of fuzzy algorithm and binary algorithm, realizes the fast and exact regulation on locomotive load. This paper introduces how to apply fuzzy and binary algorithm to regulate the dry resistor-load and explains the realization of the fuzzy and binary algorithm.
