[0024] An embodiment of the present invention provides a helicopter IP phone command device based on a satellite link, Figure 1 This is a schematic diagram of a helicopter IP phone command device based on a satellite link provided in an embodiment of the present invention, as Figure 1As shown, it includes:

[0025] The IP phone 101 is used to enable the internal personnel of the helicopter crew to access the Public Switched Telephone Network (PSTN) through a satellite link to achieve voice calls, and the external personnel of the crew can call the internal personnel of the crew by accessing the PSTN.

[0026] The voice distributor 102 is used to receive the command information of the external voice channel of the crew, set up multiple independent voice channels, control each independent voice channel to access the internal voice channel of the crew, so that the internal personnel of the crew can receive the command information uniformly, and control each independent voice channel to access the external voice channel of the crew, so that the internal personnel of the crew can output voice information in the external voice channel.

[0027] The helicopter IP phone command device based on the satellite link proposed in the embodiment of the present invention realizes voice calls by accessing the Public Switched Telephone Network (PSTN), sets up independent voice channels to convey the command information outside the aircraft, and isolates the internal voice channels of the aircraft, effectively ensuring real-time communication of the helicopter during emergency operations and supporting the development of emergency operations.

[0028] In one embodiment, the IP phone 101 is specifically used for:

[0029] The internal personnel of the crew use the IP phone to register and access the PSTN through the satellite channel, and call a fixed phone or a mobile phone to achieve voice calls.

[0030] The external personnel of the crew call the internal personnel of the crew by accessing the PSTN and dialing a fixed number.

[0031] In one embodiment, the IP phone 101 is also used for:

[0032] Detecting voice activity, generating comfortable background noise, detecting background noise, noise reduction, and packet loss compensation.

[0033] In one embodiment, it further includes:

[0034] The airborne mobile satellite antenna is used to receive and transmit satellite signals and return audio signals in the airborne environment of the helicopter.

[0035] Specifically, when implemented, the airborne station uses a 0.4-meter Ka-band airborne mobile satellite antenna (GA400-Ka). This airborne antenna integrates an internal power amplifier and an optimized airborne modulation and demodulation modem, meeting the high-speed return requirements of helicopter video, audio, images, and data under rotor occlusion. The weight of this satellite does not exceed 20 kg, and the size does not exceed 530 mm * 390 mm.

[0036] Figure 2 It is an example diagram of the helicopter IP phone command device based on the satellite link provided in the embodiment of the present invention, as Figure 2As shown, in one example, the helicopter IP telephone command device based on a satellite link includes a satellite master station antenna, Zhongxing, an airborne satellite antenna, an airborne satellite modem, an aircraft interphone system, an interphone control and processing module, a voice distributor, headphones / helmet, a line control switch, and a power supply.

[0037] In specific implementation, the VoIP technology is adopted and an IP phone is equipped to realize the voice call function between on-board personnel and ground personnel. The on-board personnel use the IP phone to register and access the PSTN (Public Switched Telephone Network, with a fixed 8-digit telephone number) through the satellite channel, so as to make calls to any landline or mobile phone. At the same time, the ground personnel can also call the on-board personnel through the landline number (the 8-digit landline number of the operator).

[0038] In one embodiment, the voice distributor 102 is specifically used for:

[0039] When an internal crew member requests to communicate actively, control each independent voice channel to exit the internal crew voice channel and retain the internal communication of the internal crew members within the internal crew voice channel.

[0040] In one embodiment, the voice distributor 102 includes:

[0041] A line controller for switching the connection status between the internal crew voice channel and the external crew voice channel.

[0042] In specific implementation, the voice distributor has a total of 6 channels and can provide simultaneous use by 6 crew members.

[0043] Operation of the voice system equipment

[0044] (1) Power on and off. Connect the power supply and press the circuit breaker. At this time, the indicator light will light up and the distributor can work normally.

[0045] (2) Switching between external call and internal call audio. The line controller switch can respectively control the access or disconnection of the audio signal of the external call to the headphones / helmet of their respective channels. When the corresponding channel accesses the external call, the microphone on the headphones / helmet can only send voice to the external call. When it is necessary to use the helicopter interphone system to speak, it is necessary to use the switch on the line controller to disconnect the external call audio. Regardless of the state of the switch, the headphones / helmet can receive the voice information from the helicopter interphone system.

[0046] (3) Fault emergency function. When the voice distributor has no power supply or fails, it will automatically disconnect the connection of the external call and make the distributor work in the internal call state. At this time, it is equivalent to directly connecting the headphones / helmet to the helicopter interphone system.

[0047] Figure 3 It is a schematic diagram of the input control of the voice distributor provided in the embodiment of the present invention, as Figure 3As shown, the switching between computer and telephone audio is completed through the selection switch on the panel. When the switch is turned to the "Computer" end, the computer audio is connected and used at this time; when the switch is turned to the "Telephone" end, the telephone audio is connected and used at this time.

[0048] In the technical solution of this application, the acquisition, transmission, storage, use, processing, etc. of data all comply with the relevant provisions of national laws and regulations.

[0049] It should be noted that in the embodiments of this application, some existing solutions in the industry such as certain software, components, models, etc. may be mentioned. They should be considered exemplary. The purpose is only to illustrate the feasibility in the implementation of the technical solution of this application, but it does not mean that the applicant has already or necessarily used this solution.
