Embodiment Construction

[0024] For a clearer understanding of the present invention, the following is a detailed description in conjunction with the accompanying drawings and embodiments:

[0025] like figure 1 As shown, the locomotive platform is a rail transit wireless communication terminal equipment based on TETRA technology, and the mainstream ARM9 processor S3C2440 with a frequency of 400M is used to develop the embedded operating system. The locomotive station can send position check request information and alarm information to the CAD server, and can receive the clock information and ATS information sent by the CAD server; it can complete the communication with the dispatching station and the fixed station; Communication with other locomotives on the line; communication with outside telephones can be accomplished through dispatching from the dispatcher.

[0026] like figure 2 As shown, the locomotive platform is mainly composed of the main engine, the control box and the antenna. The main...

Abstract

The invention relates to rail transit wireless communication terminal equipment based on TETRA. The equipment is a locomotive station, is respectively and wirelessly communicated with a CAD server, a dispatching station, a fixed station, other locomotive stations and outside calls through wireless network coverage, and comprises a control box, a host, an antenna, an application layer program, a recording program, an interface management program and a call service interface program. The control box comprises a displaying and operating unit, a control unit and a recoding unit; the host comprises a power supply unit, a switchover unit and a TETRA module. Compared with several kinds of digital trunked systems, the rail transit wireless communication terminal equipment based on the TETRA has the advantages of being complete in commanding and dispatching function, flexible in networking mode, high in antijamming capability, high in spectrum utilization rate, large in system capacity, capable of providing voice and data communication service and flexible network management functions, high in encryption and off-Internet function and the like, can achieve an off-Internet direct connection mode and end-to-end encryption and meets the demands of providing high-quality locomotive stations for current light rail transit.

Description

technical field [0001] The present 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, trunked mobile communication is gradually moving from the analog age to the digital age. Due to the low frequency of the analog trunking 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; mobile devices are expensive, bulky, and difficult to control network management. . Therefore, the use of TETRA wireless communication system in the field of light rail and subway has been generally recognized at home and abroad. Almost all domestic light rail subway projects have adopted the TETRA system, and places such as civil aviation airports have also begun to use the TETRA system. It can be s...
