Controlled train tail apparatus

Abstract

The invention discloses a controllable train rear device, and belongs to a railway transportation field. The device comprises a driver control box connected with a locomotive operation monitoring device via a RS485 serial port; a data wireless transmission device including a ground application node, a GSM-R network, a vehicle-carried communication unit (OCU), and a GSM-R digital processing module(TCU). The vehicle-carried communication unit (OCU) and the GSM-R digital processing module (TCU) are connected with the ground application node. The ground application node is disposed in a ground machine room. The vehicle-carried communication unit (OCU) is disposed in the driving cab of a train locomotive. The GSM-R digital processing module (TCU) is disposed at the train rear. The vehicle-carried communication unit (OCU) is connected with the driver control box via a RS422 serial port. A mainframe is connected with the GSM-R digital processing module (TCU) via a RS422 serial port. With thedevice, the front and rear portions of the train can be synchronously braked.

Description

technical field [0001] The invention relates to a train tail device, which realizes the controllability of the air exhaust and decompression amount at the tail of the train and the synchronization with the air exhaust of the leading locomotive. It belongs to the field of railway transportation equipment technology and equipment. Background technique [0002] At present, the functions and functions of the tailing devices produced by various manufacturers in China and the tailing devices produced abroad are similar. Although all have the function of exhaust and decompression, the setting of this function is only for assisting the lead locomotive to brake the train under the situation of weak train braking (generally when the corner cock of the vehicle is closed). Its braking function is the maximum decompression in emergency braking or normal braking, and does not have a synchronous braking function that can control the decompression amount. [0003] At the same time, the tr...

Problems solved by technology

[0003] At the same time, the transmission of decompression and exhaust commands between the tail unit and the lead locomotive still relies on the traditional analog communication method. The reliability and real-time performance of the communication cannot fully meet the actual needs, which seriously affects the safety and efficiency of train operation.

[0004] In the field of railway transportation, especially when heavy-duty long trains are braking, due to the long distance between the head and the tail of the train, the decompression and exhaust effect of the main locomotive cannot be fully applied to the entire train at the same time, which will cause the braking speed of the entire train to decrease. Slow, large longitudinal impulse of the train, long braking distance of the train, etc., so the main locomotive at the head of the train and the rear of the train must perform synchronous exhaust braking

The function and performance of the existing train tail device cannot meet the control requirements of the main locomotive at the head of the heavy-duty train and the rear of the train for simultaneous exhaust and decompression
