Detailed Description
The technical scheme of the invention is clearly and completely described below by combining the embodiment and the attached drawings of the specification. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Research shows that one type of signals are suitable for long-distance transmission, the safety of the signals is guaranteed in the signal transmission process, and the signals are high in stability in the transmission process and are not easily interfered by noise signals. However, the signals with the above characteristics have high time delay and high frequency, and once the signals enter the voice channel, high-definition voice cannot be used due to poor voice channel quality, and the signals are interrupted once the signals enter the voice channel.
In order to solve the technical problem, the invention provides a satellite fax signal conversion transmission method, a satellite fax signal conversion transmission device, a device terminal and a storage medium, and solves the problem of interruption during transmission in a signal voice channel. In specific implementation, a signal transmitted from another communication device is first acquired, the signal is recorded as a first signal, then the first signal is converted into a second signal, the second signal is suitable for being transmitted in a voice channel (channel), and then the second signal is transmitted in the voice channel to a terminal located in the voice channel. The second signal is transmitted in the voice channel with little distortion and can be completely received by the terminal. The signal is converted, the converted signal can be received by the terminal located in the voice channel, and the terminal receives the high-quality signal, so that the information carried by the signal is well received by the terminal.
For example, signal transmission is performed between a satellite and a telephone, the satellite transmits an electromagnetic wave signal suitable for long-distance transmission, and the electromagnetic wave signal is high in delay, poor in voice channel quality and incapable of using high-definition voice, so that the electromagnetic wave signal transmitted by the satellite cannot directly carry fax signals and data in the voice channel to perform fax receiving and sending, and further a terminal such as a telephone adopting the voice channel cannot receive the electromagnetic wave signal transmitted by the satellite. The present embodiment provides a fax server on a communication channel between a satellite and a telephone, the fax server converting an electromagnetic wave signal into a voice signal, and the voice signal can be transmitted without interruption and distortion in the voice channel. In this embodiment, the fax server transmits the converted voice signal to the fixed-network fax machine located at the fax communication end of the telephone, and then the fixed-network fax machine transmits the voice signal to the telephone.
Exemplary method
The name method of the embodiment can be applied to terminal equipment, and the terminal equipment can be a terminal product with a video playing function, such as a television, a computer and the like. In this embodiment, as shown in fig. 1, the method for converting and transmitting a satellite fax signal specifically includes the following steps:
step S100, obtaining signals to be converted with discontinuous amplitude values;
the signal to be converted comprises a fax instruction signal and a fax signal, the fax instruction signal is firstly acquired, and the fax signal is received after the communication channel is established.
For example, when the satellite communication device needs to transmit the acquired information, a fax instruction signal is first sent to the telephone terminal, the instruction signal is transmitted to the telephone terminal in the form of a digital signal, and the telephone is located in the voice channel, so that the capability of capturing the digital signal is poor. Then the satellite communication equipment sends the fax signal carrying the specific information content to the fixed network of the telephone communication equipment. The fax server also converts the fax signal in the form of digital signal to obtain voice fax signal. Wherein, it should be noted that, in order to transmit signals to the telephone communication device, the satellite communication device first needs to receive signals transmitted from other communication devices, the satellite terminal of the satellite communication device converts analog signals acquired from other communication devices into digital signals, the high-orbit satellite of the satellite communication device transmits the digital signals as signals to be converted to the fax server,
step S200, converting the signal with discontinuous amplitude in the signal to be converted to obtain a target signal with continuous amplitude, which comprises the following steps: and inputting the signal to be converted into a weight resistance network conversion algorithm to obtain the target signal.
The signal to be converted comprises a fax instruction signal and a fax signal. The satellite communication equipment receives a fax signal to be transmitted to the telephone communication equipment, and needs to send a fax instruction signal to the telephone communication equipment, and then a fax server on a communication channel between the satellite communication equipment and the telephone communication equipment establishes a voice channel for transmitting the signal with the telephone communication equipment. In order to ensure that the fax signals carrying specific information can be continuously and rapidly transmitted, a weight resistance network conversion algorithm in the fax server firstly converts all the fax signals to be transmitted into voice fax signals, so that once the voice channel is established, the voice fax signals can be continuously transmitted to the telephone communication equipment without interruption.
Step S300, establishing a voice channel, and transmitting the target signal to a terminal along the voice channel, as shown in fig. 2, includes:
step S301, converting the fax instruction signal into a voice fax instruction and converting the fax signal into a voice fax signal;
step S302, establishing an instruction voice channel;
step S303, transmitting the voice fax instruction to a terminal along the instruction voice channel;
step S304, after the voice fax instruction is transmitted to the terminal, a fax voice channel is established;
step S305, the voice fax signal is transmitted to the terminal along the fax voice channel.
The frequency of the voice fax instruction is 1000HZ to 1200HZ, and the frequency of the voice fax instruction in the embodiment is 1100 HZ. The establishment of the facsimile voice channel and the conversion of the facsimile signal into a voice facsimile signal are all performed in synchronization. Before the fax voice channel is established, all fax signals need to be converted into voice fax signals, and all voice fax signals need to be stored in a fax server. According to the operation, the two channels are established, so that the instruction and the signal carrying the information are positioned in different channels, the instruction and the signal carrying the information do not interfere with each other, and the efficiency of signal transmission can be improved. And the fax signals are transmitted after being converted into the voice fax signals, so that the voice fax signals can be continuously transmitted to the telephone communication equipment without interruption, and the stability of the telephone communication equipment for receiving the signals is ensured.
For example, when a satellite terminal of a satellite communication device needs to transmit a fax signal to a fixed network of a telephone communication device, the satellite terminal transmits a fax start event (instruction) to a fax server. After receiving the fax notification from the satellite terminal, the fax server sends fax signal sound and establishes a fax with the fixed network through rtp (Real-time Transport Protocol). The fax server receives the voice algorithm negotiated by the fixed network, sends the voice fax signal stored by the fax server to the fixed network according to the rtp protocol format, and the fax server can normally generate fax signal sound without running special DSP software when the fixed network receives the fax signal in the rtp stream.
In summary, signals are firstly transmitted in a form suitable for long-distance transmission, and signals suitable for long-distance transmission are not suitable for transmission in a voice channel, but in practical use, signals need to be transmitted in different channels, once signals suitable for long-distance transmission directly enter the voice channel without conversion, signal interruption and distortion are caused, and then terminals located in the voice channel cannot receive the signals, so that information is lost.
The signal is converted, the converted signal can be received by the terminal positioned in the voice channel, and the high-quality signal received by the terminal enables information carried by the signal to be well received by the terminal, namely the information loss can be reduced to the maximum extent. The method and the device convert the signal into the signal suitable for being transmitted in the voice channel, so that the signal can be intuitively received by the terminal user, and the terminal user can obtain a continuous signal, so that the use requirement of the terminal user can be met.
