Embodiment Construction

[0035] The core of the present invention is to provide a control method and system for static braking of a locomotive, so that when the motor vehicle is stopped and restarted on a long downhill slope, sufficient braking force can be effectively provided when the motor vehicle is relieved.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0037] Please refer to figure 1 , which shows a flow chart of Embodiment 1 of a control method for static holding braking of a locomotive according to the present application, which may include t...

Abstract

The invention provides a control method for static-state holding brake of a locomotive. The method comprises steps as follows: triggering a static-state holding brake instruction under the condition that the static-state holding brake of the locomotive is available; controlling an air inlet to be powered on and an air outlet to be powered off according to the static-state holding brake instruction to form an air charging passage at the air inlet, and closing the air outlet to forbid exhaust; charging main air into the air charging passage; detecting the pressure of the main air charged into the air charging passage, and stopping charging the main air and closing the air charging passage if the pressure of the main air reaches a first preset threshold; comparing the pressure of the main air charged into the air charging passage with the pre-control pressure, and enabling the locomotive to obtain a static-state brake force larger than that under the normal brake condition if the pressure of the main air is higher than the pre-control pressure. With the adoption of the control method for static-state holding brake of the locomotive, the brake time of the locomotive can be effectively prolonged, so that the locomotive can obtain the static-state brake force larger than that under the normal brake condition.

Description

technical field [0001] The present application relates to the field of locomotive vehicle braking control, in particular to a control method and system for static holding braking of a locomotive. Background technique [0002] With the development of the economy, the number of motor vehicles in my country is increasing, and the phenomenon of traffic jams is becoming more and more serious. It is more and more common for motor vehicles to start after braking and parking on a downhill slope. [0003] At present, when a motor vehicle restarts after stopping on a long downhill slope, in order to prevent insufficient air filling of the train tube when braking again, the motor vehicle is generally used to implement the maximum individual braking, the vehicle is relieved, and the air charging pipeline is used to fill the air, and the locomotive is used The braking force offsets part of the sliding force of the vehicle, buys time for full pipeline refilling, and ensures the braking ca...
