Controllable train tail system

Abstract

The invention discloses a controllable train tail system, which comprises a locomotive part, a controllable train tail part and a monitoring and auxiliary maintenance system, wherein when a locomotive brake is operated to reduce pressure, the pressure of an equalizing reservoir and the pressure of a main air pipe are transferred to a train tail driver control box by a locomotive operation monitoring device; the driver control box sends the pressure reduction information to a locomotive main machine part; the locomotive main machine exchanges data with a train tail communication part in a train tail main machine hung at the train tail part through a telecommunication module; the train tail main machine sends related data to the control unit of the train tail main machine; and the control unit exhausts air and reduces pressure through a controllable electromagnet valve according to the pressure reduction information transferred by the locomotive. The universal controllable train tail system is capable of realizing the synchronous controllable brake of the tail part of a heavy-loaded, long and large train and a traction locomotive without global system for mobile communications-railway (GSM-R) network coverage. The controllable train tail system shortens time for braking operation of the train, improves the operation safety of the train and reduces bad influences of train braking on a line.

Description

technical field [0001] The invention belongs to the field of train braking, in particular to a controllable train tail system. Background technique [0002] With the rapid development of my country's railways and the formulation of China's railway medium and long-term development plan, heavy-haul transportation will be the key energy transportation mode for my country's railways in the future. With the running of heavy-duty trains, the synchronous braking and safe braking of heavy-duty long-distance trains have become problems to be solved urgently. [0003] When the traditional train tail system assists in braking, because the braking pressure is uncontrollable, it can only assist in emergency braking in emergency situations, but cannot achieve synchronous controllable braking with the traction locomotive during train operation. [0004] On the Daqin Line covered by the GSM-R network, the controllable train tail system, which can realize the synchronous controllable brakin...
