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 a control seat and a radio station gateway or a VoIP station by utilizing an SIP protocol;
s2, a controller transmits a voice signal;
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;

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.
