Wireless communication device

Abstract

Embodiments of the invention provide a wireless communication device. The wireless communication device comprises a signal receiving-transmitting unit, a signal distribution unit, a communication demodulation unit and an early warning demodulation unit, wherein the signal distribution unit is separately connected with the signal receiving-transmitting unit, the communication demodulation unit andthe early warning demodulation unit; the signal distribution unit is used for confirming a signal received by the signal receiving-transmitting unit as a communication signal or an early warning signal and transmitting the communication signal to the communication demodulation unit and transmitting the early warning signal to the early warning demodulation unit; the communication demodulation unitis used for demodulating the communication signal and acquiring communication information; and the early warning demodulation unit is used for demodulating the early warning signal and acquiring theearly warning information. By adopting the device provided by the embodiments of the invention, the integration of communication and early warning is realized, a train early warning function for the working personnel along the railway line can be realized on the premise of not adding extra devices, the load of the working personnel is alleviated, the safety protection efficiency is improved, and the safety protection cost is decreased.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a wireless communication device. Background technique [0002] With the continuous improvement of the running speed of railway trains, the staff along the railway cannot know the running status of the train in time, and the personal safety problems of the staff along the railway caused by this have become increasingly prominent. [0003] At present, when the staff along the railway line are working on the track, they usually use a hand-held intercom radio. Yet the existing hand-held intercom radio only possesses the call function, and does not possess the early warning function of the train approaching. Most of the existing early warning equipment suitable for workers along the railway line have the problems of poor reliability and unstable performance. [0004] Since such early warning devices are mostly set separately, adding one early warn...
