Method and device for modulating and demodulating ground-air wireless communication digital identity information

Abstract

The invention discloses a method for modulating and demodulating ground-air wireless communication digital identity information. The method comprises: when it is detected that the PTT switch is pressed, the PTT switch being in an audio sending state, modulating the digital identity information of the sending end into audio, the digital identity information comprising identity identification information and call serial number information, and loading the modulated audio at the head or tail of the call audio; and receiving the audio of the air-ground radio station according to the fact that thePTT switch is loosened and is in an audio receiving state, demodulating to obtain digital identity information, and sending out the digital identity information according to the configured parameters.According to the invention, on the premise that normal ground-air wireless voice communication is not influenced, the digital identity information is added into the call voice in real time, the digital identity recognition capability is added into an original analog communication channel, and the digital identity recognition capability is used for identifying the identity and the call sequence ofa caller in real-time call and after-event analysis, so that the risk of safety events such as mistakes, forgetting and missing which easily occur in the use of a half-duplex communication radio station is conveniently judged, and the safety of command call is improved.

Description

technical field [0001] The invention relates to the technical field of ground-air communication, in particular to a modulation and demodulation method and device for digital identity information of ground-air wireless communication. Background technique [0002] The existing air traffic control command mode is a human-in-the-loop mode, that is, the controller relies on the ground-air VHF radio station to communicate with the real-time air situation based on the integrated monitoring information, flight plan, and weather information provided by the air traffic control automation system (ATC). Conversational command and control. [0003] The ground-to-air communication between controllers and pilots is carried out in accordance with the "Air Traffic Radio Communication Terms (MH / T 4014-2003)". Ground-to-air communication generally uses radio communication (VHF / HF), which is widely used because of its stability and reliability. Such as commonly used VHF radio, 25khz bandwidth...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a modulation and demodulation method and device for ground-air wireless communication digital identity information in view of the problems in the prior art that the cost of uplink and downlink communication is high, voice data are mixed together, and cannot be distinguished intuitively. The invention can load the identity identification audio into the call audio at the audio sending end without affecting the normal voice call, and can also load the call sequence number audio, receive and demodulate at the audio receiving end, and obtain the identity information of the caller and the call time. Label and other information, easy to distinguish and store call data
