And S20, when the radio station receives the normal polarity signal, the radio station monitors the audio signal of the external radio station and sends the audio signal to the docking equipment through the telephone cable, so that the audio signal is sent between the radio station and the docking equipment.
Specifically, when the radio station monitors a normal polarity signal, it indicates that the PTT signal is in an idle state, and at this time, the radio station is in a monitoring state to monitor an audio signal of an external radio station, and when the audio signal is monitored, the audio signal is sent to the docking device, and at this time, the radio station may send to the docking device through a normal polarity line sequence.
In one embodiment of the invention, the method further comprises:
s30, when the docking equipment sends the audio signal to the radio station, the docking equipment sends a PTT signal to the radio station through the reverse polarity signal of the telephone cable;
and S40, when the radio station receives the PTT signal, the radio station receives the audio signal sent by the docking equipment through the telephone cable and sends the audio signal in the form of a radio frequency signal.
Specifically, when the docking device wants the radio station to transmit an audio signal, it needs to occupy the PTT signal, and at this time, the docking device may transmit a reverse polarity signal to the radio station as the PTT signal, so that the radio station determines that the PTT signal is occupied. Accordingly, when the dock sends an audio signal to the radio station, the sending, by the dock, a PTT signal to the radio station via the reverse polarity signal of the telephone cable specifically includes:
s41, when the docking equipment sends the audio signal to the radio station, the docking equipment extracts the normal polarity line sequence of the docking equipment;
and S42, reversing the normal polarity line sequence and sending a reverse polarity signal to the radio station through the reversed line sequence so as to realize sending the PTT signal to the radio station.
