Abstract

The invention provides 450MHz digital-analog compatible locomotive comprehensive wireless communication equipment. The locomotive comprehensive wireless communication equipment comprises an antenna feeder unit respectively connected with a 450MHz communication unit, a GSM-R communication unit and a satellite receiving unit; the 450MHz communication unit, the GSM-R communication unit and the satellite receiving unit are connected with a master control/interface unit; the master control/interface unit is further connected with a recording unit, a power supply unit, a MMI unit and multiple auxiliary function modules. The 450MHz communication unit in the wireless communication equipment provided by the invention has two channel machine control interfaces, the 450MHz digital-analog compatible digital channel machine is adopted, two parallel logic channels are supported on 12.5MHz carrier since the channel machine adopts the TDMA time-division technology, and the use ratio of the frequency spectrum is improved; the inhibition of the environment noise is solved by using the DSP voice processing technology; and the security of the communication is effectively improved by using the digital encryption and authentication at the same time.

Description

technical field [0001] The invention relates to a wireless communication device, in particular to a 450MHz digital-analog compatible integrated wireless communication device for locomotives. 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] With the acceleration of existing railway lines and the large-scale construction of high-speed railways, the existing analog wireless train dispatching system has defects such as single function, low frequency utilization rate, multiple users competing for channels, and non-uniform standards, which can no longer adapt to technological development and The needs of modern transportation...
