Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is
Some embodiments of the utility model, for those of ordinary skill in the art, without creative efforts,
It is also possible to obtain other drawings based on these drawings.
Fig. 1 is a kind of wireless communication device structural schematic diagram of the utility model embodiment.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
Fig. 1 is a kind of wireless communication device structural schematic diagram of the utility model embodiment, as shown in Figure 1, a kind of wireless
Communication device, including signal transmitting and receiving unit 101, signal Dispatching Unit 102, communication demodulating unit 103 and early warning demodulating unit
104；Wherein, the signal Dispatching Unit 102 respectively with the signal transmitting and receiving unit 101, communicate demodulating unit 103 and early warning solution
Unit 104 is adjusted to connect；The signal Dispatching Unit 102 is for confirming 101 received signal of signal transmitting and receiving unit for communication
Signal or pre-warning signal, and the communication demodulating unit 103 is sent by the signal of communication, it sends the pre-warning signal to
The early warning demodulating unit 104；The communication demodulating unit 103 obtains the communication information for demodulating the signal of communication；It is described
Early warning demodulating unit 104 obtains warning information for demodulating the pre-warning signal.
Specifically, the signal transmitting and receiving unit 101 is a kind of component of electromagnetic wave for transmitting and receiving, and the signal is received
Bill member 101 emits electromagnetic wave and refers to that the guided wave that will be propagated on transmission line is transformed into the electromagnetic wave propagated in unbounded medium,
The signal transmitting and receiving unit 101 receives electromagnetic wave and refers to the electromagnetic waveform propagated in unbounded medium at propagating on transmission line
Guided wave, i.e., the described signal transmitting and receiving unit 101 is that one kind has reversible converter.The signal transmitting and receiving unit 101 has
Standby a variety of ways of realization, such as antenna, the utility model embodiment are not especially limited this.
In the utility model embodiment, the signal transmitting and receiving unit 101 receives electromagnetic wave and is converted to guided wave signal, with
The signal is transferred to the signal Dispatching Unit 102 connecting with the signal transmitting and receiving unit 101 afterwards.
The signal Dispatching Unit 102 is for being distributed the signal transmitting and receiving unit received signal:
The signal Dispatching Unit 102 judges currently received signal for signal of communication or pre-warning signal.Since communication is believed
Number from pre-warning signal occupy frequency range it is different, its corresponding judgment basis can be reception the occupied frequency range of signal.
If the frequency range that currently received signal occupies belongs to communication signal frequency band, the currently received signal is confirmed
For signal of communication, and it is transferred to communication demodulating unit 103；
If the frequency range that currently received signal occupies belongs to pre-warning signal frequency range, the currently received signal is confirmed
For pre-warning signal, and it is transferred to early warning demodulating unit 104.
After the communication demodulating unit 103 receives the signal of communication that the signal Dispatching Unit 102 transmits, to described logical
Letter signal is demodulated, and the communication information is obtained.Similarly, the early warning demodulating unit 104 receives the signal Dispatching Unit
After the pre-warning signal of 102 transmission, the pre-warning signal is demodulated, obtains warning information.Wherein, the demodulation refers to from taking
Restore message in modulated signal with message and extracts the process of useful information.
From the foregoing, it will be observed that signal of communication and pre-warning signal pass through after signal transmitting and receiving unit 101 receives by signal Dispatching Unit 102
It is distributed to corresponding demodulating unit to be demodulated, communication demodulating unit 103 and early warning demodulating unit 104 are respectively independent, do not do mutually
It disturbs.Therefore, the device that the utility model embodiment proposes, realizes the integration of communication and early warning, is not increasing extras
Under the premise of realize train warning function for Along Railway staff, alleviate the burden of staff, improve
Security protection efficiency reduces security protection cost.
