Specifically, the signal receiving and transmitting unit 101 is a component for transmitting and receiving electromagnetic waves, the signal receiving and transmitting unit 101 transmits electromagnetic waves to convert guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium, and the signal receiving and transmitting unit 101 receives electromagnetic waves to convert electromagnetic waves propagating in an unbounded medium into guided waves propagating on a transmission line, that is, the signal receiving and transmitting unit 101 is a reversible transformer. The signal transceiver unit 101 is provided with various implementation forms, such as an antenna, which is not particularly limited in the embodiment of the present invention.
In the embodiment of the present invention, the signal transceiver unit 101 receives electromagnetic waves and converts the electromagnetic waves into guided wave signals, and then transmits the signals to the signal distribution unit 102 connected to the signal transceiver unit 101.
The signal distribution unit 102 is configured to distribute the signal received by the signal transceiver unit:
the signal distribution unit 102 determines that the currently received signal is a communication signal or an early warning signal. Because the frequency band occupied by the communication signal and the early warning signal is different, the corresponding judgment basis can be the frequency band occupied by the received signal.
If the frequency band occupied by the currently received signal belongs to the communication signal frequency band, the currently received signal is confirmed to be a communication signal and transmitted to the communication demodulation unit 103;
if the frequency band occupied by the currently received signal belongs to the early warning signal frequency band, the currently received signal is confirmed to be an early warning signal and transmitted to the early warning demodulation unit 104.
The communication demodulation unit 103 demodulates the communication signal after receiving the communication signal transmitted by the signal distribution unit 102, to obtain communication information. Similarly, after the early warning demodulation unit 104 receives the early warning signal transmitted by the signal distribution unit 102, the early warning signal is demodulated, and early warning information is obtained. Wherein the demodulation refers to the process of recovering a message from a modulated signal carrying the message and extracting useful information.

For the communication demodulation unit 103, if the currently received signal is of a communication format, the currently received signal is confirmed as a communication signal, and the communication signal is demodulated; otherwise, the currently received signal is not demodulated. Aiming at the early warning demodulation unit 104, if the currently received signal is in an early warning mode, the currently received signal is confirmed to be an early warning signal, and the early warning signal is demodulated; otherwise, the currently received signal is not demodulated.

The communication modulation unit then transmits the voice information to the signal distribution unit, and transmits the voice information to the signal transceiving unit via the signal distribution unit to be transmitted.
In the embodiment of the invention, the function of transmitting voice information is added to the wireless communication device on the basis of the original received communication information and early warning information, so that the communication function of the wireless communication device is completely realized.
Based on any one of the above embodiments, a wireless communication device further includes a sound reception unit; the radio unit is connected with the communication modulation unit; the radio unit is used for collecting voice and transmitting the voice coded into voice information to the communication modulation unit.
Specifically, the sound receiving unit is an energy conversion device for converting sound signals into electric signals, and has the functions of acquisition and coding, and is used for acquiring voice and coding the voice into voice information. Here, the voice refers to sound that a worker intends to transmit through the wireless communication device, and the voice information refers to an electric signal that the voice generates through conversion of the sound receiving unit.

When the processing unit receives new early warning information, the processing unit can extract the train number from the early warning information, search the early warning information confirmation information stored in the storage unit according to the train number, and if the early warning information confirmation information containing the train number exists, namely, the user already knows the early warning information of the train corresponding to the train number and confirms the early warning information of the train corresponding to the train number through the interaction unit. In this case, the processing unit no longer transmits the pre-warning information to the interaction unit for playing.

The processing unit can also send instructions to the interaction unit to control the interaction unit to broadcast and/or display the early warning information obtained after demodulation by the early warning demodulation unit. Meanwhile, the processing unit can also send instructions to the interaction unit to control the interaction unit to broadcast and/or display the communication information obtained after demodulation by the communication demodulation unit, and in addition, the processing unit can also send instructions to the communication modulation unit to control the communication modulation unit to encode the voice information collected by the radio unit into voice information and send the voice information through the signal distribution unit.

Based on any of the above embodiments, a wireless communication device, the interaction unit includes a display subunit and/or a sound-emitting subunit.

For example, the processing unit can generate corresponding words and/or images according to the early warning information, send the words and/or images to the display subunit, and then the display subunit displays relevant information of the train corresponding to the early warning information to the staff in the form of words and/or images, for example, displays train number and train speed by words, and marks the train running route and the current position of the train in a map.
The processing unit can also acquire the recognition text corresponding to the communication information through voice recognition, and send the recognition text to the display subunit, and then the display subunit displays the recognition text corresponding to the communication information to staff in a text mode.
For another example, the sounding subunit can directly perform digital-to-analog conversion on the early warning information and/or the communication information, generate corresponding prompt voice, and play the prompt voice.

The expected arrival time was 3min, as known from the train speed of 200km/h and the travel distance of 10km.
In the embodiment of the invention, the acquisition of the estimated arrival time has important significance for prompting the staff to withdraw the line strand in time.
