At present, the ground-air voice communication means mainly adopt very high frequency communication, in order to solve the sight distance propagation limitation and the terrain influence of the very high frequency communication, improve the reliability of the ground-air voice communication and ensure the flight safety, the common-frequency different-address station is generally adopted to effectively cover the whole communication field. Meanwhile, with the rapid development of the civil aviation transportation industry, the number of current flights is rapidly increased, and the demand for the number of very high frequency stations is increased day by day. Therefore, when the controller and the pilot perform ground-air voice communication, the controller needs to perform station switching continuously, which undoubtedly increases the workload and working pressure of the controller, and meanwhile, multiple channels of same-frequency different-address voice signals enter the air-pipe voice system, while the number of channels of the air-pipe control seat is limited, and multiple channels of same-frequency different-address voice signals cause the time slot shortage of the internal voice loop.
In order to ensure the voice quality of ground-air communication and reduce the workload and working pressure of a controller, a traditional internal communication system generally uses a comparison selector, when receiving a voice signal sent by a pilot, a very high frequency station signal is sent into the comparison selector, the comparison selector selects the station voice with the best quality and outputs the station voice to a control seat, so that the controller always receives the signal with the best effect, when the controller sends the signal, the controller voice is sent to the comparison selector through the control seat, and the controller voice is sent to the pilot according to a preset mode so as to ensure that the two-way voice is in the best state.

Detailed Description
Referring to fig. 1, a transmission following method based on VoIP ground-to-air voice communication comprises the following sub-steps:
s1, establishing SIP communication connection between the control seat and the radio station gateway or VoIP station by using SIP protocol;
s2, the controller transmits voice signals;
the controller can manually select a certain wireless channel to transmit voice signals, and can also set an automatic selection mode, when the voice signals are transmitted within a certain time range, the wireless channel with the best received signals is automatically selected to transmit, and if the voice signals exceed the time range, one or more wireless channels are automatically selected to transmit.
When the automatic selection mode is set by a controller, the following substeps are included:
s201, setting automatic selection time of a transmitting channel, wherein the setting range is 0-60S, and the stepping value is 1S;
s202, starting a transmission following function under a certain frequency of a control seat;
s203, recording comparison and selection information of each station under the frequency and the time for finishing receiving voice;
s204, when the seat presses the PTT, checking the number of links under the frequency, if the seat is only connected with one station by the SIP, using the station to carry out the empty transmission, and if the number of the SIP links under the frequency is more than 1, executing the step S205;

s206, carrying out empty transmission according to the set station; if one station is set, the first station for establishing the SIP link is used for transmitting, and if a plurality of stations are selected, the voice signals are transmitted to all the stations for establishing the SIP link under the frequency.
In step S201, after the time-out range is set, one or more stations are used for transmission.
The specific workflow principle of this embodiment is as follows:
the embodiment is based on soft switch technology, adopts a distributed architecture, and the main nodes in the system comprise a network switching subsystem (router and switch), a control seat, a VoIP station, a radio gateway, an analog station and the like. The analog station and the VoIP station are arranged along a flight line, and cover the whole communication field. The simulation station accesses the system through the radio station gateway, and control messages and voice messages between the control seat and the very high frequency station are transmitted in real time on the IP switching network platform, so that the voice communication between the ground and the aerial platform is realized.
The regulated seat transmissions are divided into a manual selection mode and an automatic selection mode. The manual selection mode is that a certain station under the frequency is manually selected by a controller for transmission. The automatic selection mode is that the station with the best received signal is automatically selected for transmission within a certain time range, and after the time range is exceeded, the first station or stations under the frequency are automatically selected for transmission.

step 1: the transmission channel automatic selection time is set in the range of 0 to 60s with a step value of 1 s.
Step 2: after the out-of-time range is set, transmission is performed using either "one" or "multiple" stations.
And step 3: and starting a transmission following function of the control seat under a certain frequency.
And 4, step 4: the radio information for each station at the frequency is recorded, as well as the time to end the reception of speech (i.e., SQU OFF).
And 5: and when the seat presses the PTT, checking the number of links under the frequency, if the seat is only connected with one station by the SIP, using the station to perform empty transmission, and if the number of the SIP links under the frequency is more than 1, entering the step 6.
Step 6: making a difference value between the current time and the voice receiving ending time of the frequency station, detecting whether the time exceeds a set time range, and if the time does not exceed the set time range, selecting the station with the best signal compared with the selection result to send the idle voice; if the set time range has been exceeded, the process proceeds to step 7.
And 7: and carrying out air transmission according to the set station. If "one" station is set, the first station to establish the SIP link is used for transmission, and if "multiple" is selected, the voice signal is delivered to all stations on the frequency to establish the SIP link.
