Research of the Precision Positioning Method for Electric Locomotive Automatic Control System

Abstract:

The operation control of coke oven electric locomotive is an essential component of automatic control of coking manufacture. It is the main problem that coking enterprises should deal with in order to ensure the safety of production. In order to change and improve the actuality of manual driving, low positioning precision, high labor intensity and low producing efficiency, this paper proposes a practical and reliable automatic control scheme of electric locomotive based on successful experiences domestic and oversea.This scheme solves the key problem of electric locomotive automatic control-precision positioning, which containes a three-laser contraposition sensor and a positioning and lightproof piece used to ensure the accuracy of parking position detection, and a segmented deceleration control method used to ensure the automatism of parking brake. According to calculations and analysis, it is shown that the scheme could meet the system precision positioning requirements.
