Embodiment Construction

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0029] The embodiment of the present invention discloses an automatic phase-passing control method for electric locomotives. By adopting on-board equipment to complete automatic phase-passing control, the electric locomotive can realize automatic phase-passing without line positioning signals such as ground magnet signals or contact network radio frequency signals. , So that electric locomotives can be used on various electrified lines.

Abstract

The invention discloses an automatic excessive-phase control method for an electric locomotive. The automatic excessive-phase control method includes acquiring kilometer post data and current locomotive speed signals of a monitoring system; computing framing signals of forecasting, stoppage, restoration and the like of automatic excessive phase according to the kilometer post data and the current locomotive speed signals; controlling discharging slope of the locomotive and controlling on/off of a main breaker after computing according to the automatic excessive phase positioning signals and completing automatic excessive phase operation. Without line location signals such as ground magnet signals or radio frequency signals, the electric locomotive can complete automatic excessive phase control, and the electric locomotive can be universal for various electrical lines.

Description

Technical field [0001] The present invention relates to the technical field of over-phase-separation control of electric locomotives, and more specifically, to an automatic phase-passing control method for electric locomotives. Background technique [0002] At present, the automatic phase separation control method of electric locomotives is mainly divided into two types according to the positioning technology. One is the positioning method of the buried magnet induction coil, and the other is the positioning method of the contact network radio frequency card. In both methods, the line positioning device sends "announcement", "forced disconnection", "recovery" and other signals to the electric locomotive. After receiving these signals, the locomotive control system performs unloading, opening / closing main disconnection, etc. automatically. control. [0003] With the two existing methods, electric locomotives will be restricted by line conditions when passing the phase-splitting are...
