Logic electric pneumatic breaking system for heavy load train and control method thereof

Abstract

The invention discloses a logic electric pneumatic breaking system for a heavy load train and a control method thereof. The logic electric pneumatic breaking system for the heavy load train comprises a locomotive unit, a vehicle unit and a train tail device, wherein the locomotive unit comprises a locomotive power supply, an electric pneumatic controller and a locomotive pneumatic brake machine; and the vehicle unit comprises a vehicle power supply, an electrical control unit and a vehicle pneumatic brake machine. In the invention, a braking system of a large long heavy duty train is controlled by a logic encoded signal, the operating signal of the locomotive pneumatic brake machine is converted into a logic electrical signal to be sent to the vehicle units by the electric pneumatic controller of the locomotive unit, the synchronous braking and relieving of all train braking systems are achieved to reduce the longitudinal impulse force and the free running time of the large long heavy duty drain in braking and relieving; other electrical signals and the air wave signal are parallel; the structures and the operation habits of the conventional automatic pneumatic brake machines of the locomotive and the vehicle are not changed, and the conventional automatic pneumatic brake machine is compatible with the logic electric pneumatic breaking system.

Description

technical field [0001] The invention relates to a logical electro-pneumatic braking system for heavy-duty trains and a control method thereof. Background technique [0002] The braking system of the existing heavy-duty train basically cannot realize the synchronous braking of the whole train braking system, and there is a large longitudinal impulse force and a long idling time during braking and relief. Contents of the invention [0003] The object of the present invention is to: aim at the above-mentioned existing problems, provide a kind of synchronous brake that can realize whole train brake system, alleviate to reduce growth, heavy-duty train braking, longitudinal impulse force and idling time when releasing A logical electro-pneumatic braking system for heavy-duty trains and a control method thereof. [0004] The technical solution of the present invention is realized in the following way: a logical electro-pneumatic braking system for heavy-duty trains, including a ...
