Embodiment Construction

[0062] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0063] Device embodiment

[0064] According to an embodiment of the present invention, a dual-mode tail-of-row device is provided, that is, a tail-of-row device with GSM-R. The dual-mode train tail device mainly includes GSM-R / GSM network transmission unit, digital / analog radio station, global positioning device, identification module, wind pressure detection unit, storage unit and main control unit, etc., and is mainly used to collect train tail The location information of the locomotive and the wind pressure information of the locomotive are compared based on the location information of the rear of the train with the line database preset in it to determine the c...

Abstract

The invention discloses a dual-mode train tail device and a control method of the dual-mode train tail device. The dual-mode train tail device is installed on the train tail portion, and is mainly used for comparing position information of the train tail portion and a line database which is preset in the dual-mode train tail device, judging the communication system of a locomotive device in a running zone of the dual-mode train tail device, and selecting the corresponding communication mode from preset communication modes according to the communication system of the locomotive device to carry out transmission; the locomotive device which corresponds to the dual-mode train tail device is used for carrying out integrity detection on the basis of the position information, sent by the dual-mode train tail device, of the train tail portion, sending a query request to the dual-mode train tail device, and sending an air exhaust instruction to the dual-mode train tail device on the basis of air pressure response information when air exhaust is needed. According to the dual-mode train tail device and the control method of the dual-mode train tail device, the defects that in the prior art, reliability is poor, real-time performance is poor, faults cannot be easily identified, and universality is poor can be overcome, and the dual-mode train tail device and the control method of the dual-mode train tail device have the advantages that reliability and real-time performance are good, the faults can be easily identified, and universality is good.

Description

technical field [0001] The present invention relates to the technical field of railway wireless communication systems, in particular to a dual-mode row tail device and a control method thereof, in particular to an uninterrupted GSM-R network coverage area and a non-GSM-R network coverage area in turn The end-of-column device used and its control method. Background technique [0002] After the guard (car captain) of the freight train was canceled, the safety protection device at the rear of the train was widely used as an effective means to control the wind pressure at the rear of the train. With a large number of applications, the rear safety protection device has become an important equipment for driving safety. [0003] At present, the end-of-line hosts used on railways generally use wireless intercom radio stations on the data transmission channel. From the perspective of transmission frequency, the end-of-line system is divided into 450MHz end-of-line system and 800MHz ...
