Embodiment Construction

[0026] The present invention will be further described below in conjunction with accompanying drawing.

[0027] figure 1 It is a schematic diagram of the overall structure of the CTCS-3 train control system that realizes two-way transmission of vehicle-ground information based on LTE-R wireless communication in the present invention, figure 1Among them, the CTCS-3 train control system includes ground equipment and on-board equipment. The ground equipment of the CTCS-3 train control system includes: Radio Blocking Center (RBC), Transponder (Fixed-Data Balise), Wayside Electronic Unit (LEU), Track Circuit (TC), Train Control Center (TCC) and Temporary Control Center (TCC) Speed ​​server (TSR Server). The invention uses the LTE-R wireless communication system as the wireless transmission system of the CTCS-3 train control signal. The LTE-R wireless communication system includes the LTE core network EPC, the LTE baseband processing unit LTE BBU, the LTE remote radio unit LTE R...

Abstract

The invention provides an LTE train control information transmission system and method, the system comprises a ground device and a vehicle-mounted device which are connected through a wireless transmission system, the wireless transmission system adopts an LTE-R wireless communication system, and the LTE-R wireless communication system comprises an LTE core network EPC, an LTE baseband processing unit LTE BBU, an LTE radio remote unit LTE RRU, an LTE vehicle-mounted wireless gateway LTE CPE, a ground IWF device and a vehicle-mounted IWF device. The LTE wireless network is adopted to replace an original GSM-R wireless bearer network, the frequency utilization rate is improved, the subsequent expansibility is high, a new 3GPP undefined QCI value is introduced into the LTE-R system, the GRB with the highest priority is provided, it is guaranteed that the LTE-R network has enough resources to transmit CTCS-3 level train control services under any condition, and under the condition of network congestion, resources of any other services can be preempted.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an LTE train control information transmission system and method. Background technique [0002] The GSM-R system is a comprehensive dedicated digital mobile communication system specially designed for railway communication. On the basis of the group call, broadcast call, and multi-priority preemptive forced demolition services of the GSMPhase2 standard protocol, the system adds location-based addressing and function addressing. It mainly provides voice communication functions such as wireless train scheduling, marshalling and shunting communication, section maintenance and repair operation communication, emergency communication, tunnel communication, etc., and can also provide data transmission channels for train automatic control and monitoring information. [0003] Because GSM-R has the functional advantage of adapting to the characteristics of railway transportat...
