Emergency railway vehicle driving control system and method thereof

Abstract

The invention discloses an emergency railway vehicle driving control system and a method thereof. The control method comprises the following steps that: when a locomotive control system receives an emergency driving mode activation signal, whether a locomotive is required to be in an emergency driving control flow is determined according to the signal; a potentiometer and an auxiliary contact are used for giving out position information of a dragging / braking handle; after the emergency driving mode is activated, the emergency driving control flow is started up; and the locomotive control system receives a signal of the auxiliary contact and controls the ascending, the maintaining and the descending of dragging force or brake force, so as to enable the locomotive to be started up, accelerated, decelerated and stopped. According to the system and the method, when the potentiometer is invalid or a modulus collecting channel of the locomotive control system has faults, during the process in which a driver moves the dragging / braking handle, the locomotive control system can receive the signal of the auxiliary contact, and whether the locomotive is required to be subjected to ascending, maintaining and descending under the dragging / braking force is determined, so that the emergency driving of the locomotive can be realized, and the running safety of railway vehicles greatly is improved.

Description

technical field [0001] The present invention relates to a rail vehicle control system and method thereof, in particular to an emergency driving control system and method applied to rail vehicles, especially AC drive electric locomotives. Background technique [0002] The main controller 2 used on the AC drive electric locomotive such as figure 1 As shown, the locomotive master controller 2 includes: a traction / brake handle 3 and a direction handle 4 . Among them, the traction / braking handle 3 has a "big zero" position, the traction area has a "traction zero" position, a "traction 2 / 3" position, and a "traction maximum" position, and the braking area has a "brake zero" position, " Brake 2 / 3" position, "brake maximum" position and other auxiliary contact hard-wired signals, the traction / brake handle 3 moves to the corresponding position to activate the corresponding signal. The potentiometer inputs DC 15V voltage, and when the traction / brake handle 3 is at the "big zero", "t...

AI Technical Summary

Problems solved by technology

Its disadvantage is that when the potentiometer fails or the analog quantity acquisition channel of the locomotive control system fails, the driver will not be able to provide the traction / braking force of the locomotive through the traction / brake handle 3, resulting in the inability of the locomotive to run and affecting the safety of railway operation
