Implement speech commander and guiding to aerospace plane in sound radio station.Speech radio station is usually half-duplex operation, i.e. speech radio station
There are a set of wireless transmitter, a certain moment, speech radio station can only operate in sending mode or reception pattern.Start shooting in speech radio station
Afterwards, automatically into reception pattern is given tacit consent to, the speech of aerospace plane can be received.
When the navigator in ground control station needs to converse to aircraft, press and given orders or instructions (PTT) on dispatch terminal
Button, dispatching host machine control speech radio station is converted to sending mode, and reiving/transmitting state instruction in radio station is navigated on dispatch terminal
After member sees that radio station enters sending mode, start to give orders or instructions.Give orders or instructions after end, commander unclamps PTT buttons, dispatching host machine control electricity
Platform is converted to reception pattern.In use, if commander sees that radio station reiving/transmitting state is not changed correctly, lead to
Cross and re-operate the methods of PTT buttons and radio station is recovered normal.Due to using special line side between ground control station and speech radio station
Formula connects, and the probability that the transmission of PTT signals is lost is extremely low, thus re-operate PTT buttons have little influence on navigator and aircraft it
Between normal talking.
In order to make full use of ground speech transceiver resource, ground speech radio station is interconnected by networking, navigator by IP network

State message transmission is lost, and ground speech radio station can not will correctly carry out the conversion of reiving/transmitting state, directly affect the transmission of speech
With reception.For the loss of speech message, due to voice be continuous signal and it is front and rear there is stronger relevance, even if speech report
Literary transmission losing rate reaches 6%, or even 10%, and receiving terminal remains able to basic complete recovery speech, therefore without considering words
The loss of sound message.
Loss problem is transmitted for PTT state messages, when traditional solution method is that navigator presses PTT and given orders or instructions, the cycle
(generally 0.5 second) produces and sent PTT state messages, and when release PTT, which is buttoned to end, to give orders or instructions, continuous cycles send three again
Secondary PTT state messages.Although this method can solve the problems, such as PTT state messages substantially, transmission is lost, and sacrifices speech
Integrality.Especially when network congestion is serious, even if receiving terminal have received partial voice message, original words can be gone back substantially
Sound, it is also possible to because PTT state messages are lost, cause all or part of speech not send, so as to influence navigator
Normal speech between aircraft communicates.Once such case is run into, only by way of re-operating PTT buttons, until
Recover normal talking.
