Rail traffic wireless communication terminal apparatus

Abstract

The invention discloses a rail traffic wireless communication terminal apparatus. The rail traffic wireless communication terminal apparatus is a locomotive station; the locomotive station wirelessly communicates with a CAD server, a dispatching station, a fixing station, other locomotive stations and outside calls respectively through wireless network coverage and includes a control box, a host machine, an antenna, an application layer program, a voice recording program, an interface management program and a call business interface program; the control box comprises a display operation unit, a control unit and a voice recording unit; and the host machine comprises a power supply unit, a switchover unit and a TETRA module. Compared with other kinds of digital trunked systems, the rail traffic wireless communication terminal apparatus of the invention has the advantages of relatively complete commanding and dispatching functions, flexible networking modes, high anti-interference ability, high spectrum utilization rate, large system capacity, capability of providing voice and data communication services and a flexible network management function, as well as strong encryption and off-network functions and the like, and can realize an off-network direct-connection mode and end-to-end encryption. With the rail traffic wireless communication terminal apparatus of the invention adopted, high-quality locomotive stations can be provided for current light rail transit.

Description

technical field [0001] The invention relates to wireless communication equipment, in particular to a rail transit wireless communication terminal equipment based on TETRA technology. Background technique [0002] At present, trunking mobile communication is gradually moving from the analog age to the digital age. Due to the low frequency of the analog cluster mobile communication network of rail transit; the types of services that can be provided are limited, and high-speed data services cannot be provided; the confidentiality is poor, and it is easy to be eavesdropped; the cost of mobile equipment is high, the volume is large, and network management is difficult to control. . Therefore, the use of TETRA wireless communication system in the field of light rail and subway has been widely recognized at home and abroad. Almost all domestic light rail and subway projects have adopted the TETRA system, and civil aviation airports and other places have also begun to use the TETRA...
