| GSM for Railway (GSM-R) in the GSM cellular system, an increase of activation of high-speed communications functions and environment suitable for use elements of the communications system, to meet the International Railway Union railway dispatch communication requirements can be achieved across borders between high-speed trains and the general train of communications, and can use the existing railway communications network integration into a single platform, to reduce integration and operating costs. The development of wireless train control communications system that based on GSM-R can overcome the many technical obstacles, improve transport efficiency, and improve service quality, thus greatly enhancing the informationization of railway transport in our railway station.The study "LCIR type motorcycle integrated communications equipment" is in the network environment sets GSM-R voice communications, data transmission in wireless integrated railway equipment. The paper made the following main arguments and research:(1) Introduced GSM-R network structure and function of fundamental characteristics.(2) According to the requirements of the system design and communications hardware agreement carried out a feasibility study, functional point of the voice communications, it has added a GPRS data communications functions, while a voice group calls, voice Group Call, multi-level priority control functions;Sphagnum GSM-R and 450M standards with automatic and manual cut over function compatible railway 450M band A,B1, B2 and C-FM radio out system;Applications have a railway emergency call, marshalling operations, multi-driver communications, train tail wind pressure, transmission and print out orders, the vehicle trips of transmission, voice and data storage and communication patterns cut over, GPS positioning location kinship and other functions.(3) System software programmer for the realization of a specific programming.(4) The equipment functional debugging a brief presentation. |
