Problems solved by technology

However, GSM-R is a narrowband communication system with low spectrum utilization, which is difficult to meet the development needs of railway broadband data services in the future; on the other hand, with the development of public mobile communication networks from 2G and 3G to 4G, the GSM market is gradually shrinking. GSM-R will lose the support of the equipment industry chain

Abstract

The invention provides a high-speed railway LTE-R locomotive integrated wireless communication device, wherein an antenna feeder unit of the high-speed railway LTE-R locomotive integrated wireless communication device are respectively in electrical connection and signal connection with a 450 MHz communication unit, an LTE-R communication unit, a GSM-R communication unit and an LBJ communication unit; the 450 MHz communication unit, the LTE-R communication unit, the GSM-R communication unit, the LBJ communication unit, an exchange unit, a recording unit, an interface unit and a power supply unit are respectively electrically connected with a main control unit; and the main control unit is in electrical connection and signal connection with an MMI unit. The high-speed railway LTE-R locomotive integrated wireless communication device realizes integration of three communication modes of LTE-R, GSM-R and 450MHz digital-to-analog compatibility, and is provided with the LBJ communication unitto realize transmission of the 800 MHz data, thereby meeting the special requirement for smooth transition of various communication modes of the railway.

Description

technical field [0001] The invention relates to a wireless communication device, in particular to a high-speed rail LTE-R locomotive comprehensive wireless communication device. Background technique [0002] The special network of railway wireless communication system is an important equipment to ensure the safety of railway traffic. There are two main types of railway wireless communication in my country. One is the train dispatching wireless communication system based on "analog wireless intercom"; the other is based on "GSM-2G "GSM-R digital mobile communication system. [0003] As the second generation of mobile communication technology, GSM-R has been widely used in my country's high-speed railway and intercity express railway. However, GSM-R is a narrowband communication system with low spectrum utilization, which is difficult to meet the development needs of railway broadband data services in the future; on the other hand, with the development of public mobile communi...
