Description

Technical Field

[0001] The present invention belongs to the technical field of communication control, and particularly relates to a telephone transceiver control terminal for a telephone guaranteed communication system. Background Art

[0002] In terms of signal transmission methods, communications are generally divided into two major categories: wire communication and radio communication. Radio communication mainly includes satellite communication, short-wave communication, ultra-short-wave communication, microwave communication, relay communication, etc. Wire communication mainly includes manual telephone communication, magneto telephone communication, automatic telephone communication, facsimile communication, computer communication, video communication, secure telephone communication, etc.

[0003] Satellite communication mainly involves communication between a satellite and a ground satellite earth station. Once the satellite is destroyed, satellite communication will lose its communication ability.

[0004] Short-wave communication mainly achieves communication by reflecting radio waves through the ionosphere. Since the ionosphere is difficult to destroy, short-wave communication is relatively reliable.

[0005] Ultra-short-wave communication mainly achieves communication through base stations and links. Once the base stations and links are destroyed, ultra-short-wave communication will lose its communication ability.

[0006] Microwave communication and relay communication are visual communications, also called line-of-sight communications. Once the microwave stations and relay stations are destroyed, microwave communication and relay communication will lose their communication ability.

[0007] Manual telephone communication, magneto telephone communication, automatic telephone communication, facsimile communication, computer communication, video communication, secure telephone communication, etc. mainly rely on an optical fiber communication transmission network to organize the network and achieve communication. Once the optical fiber transmission stations and optical cable lines are destroyed, manual telephone communication, magneto telephone communication, automatic telephone communication, facsimile communication, computer communication, video communication, secure telephone communication, etc. will all lose their communication ability.

[0057] The converter completes the conversion of the functions of magneto telephone communication and wireless telephone communication by controlling the switching between the microphone and the speaker and between the receiver and the earpiece.

[0058] When the functions of two new guaranteed telephone communication telephone terminals are set in the magneto telephone communication state, after connecting the two new guaranteed telephone communication telephone terminals through connection lines such as the paired wire, audio cable, network cable, twisted pair, etc., long-distance, "point-to-point" magneto telephone communication can be realized.

[0059] The present invention can complete wireless telephone communication. When the functions of two new guaranteed-communication telephone terminals are set in the magneto-telephone communication state, the ringing signal (25 Hz, 60 - 130 V AC voltage) is converted into a fixed Morse telegraph code, and the voice signal is converted into a Morse telegraph code. Information transmission is completed through a wireless transceiver, enabling long-distance "point-to-point" wireless telephone communication.

[0061] The converter has two working states. One is the magneto-telephone state, and the other is the wireless-telephone state. When the converter is in the magneto-telephone state, the RJ11-11 interfaces of two new guaranteed-communication telephone terminals are connected through transmission media such as paired wires, audio cables, network cables, and twisted pairs, and magneto-telephone communication can be established between the two new guaranteed-communication telephone terminals; the new guaranteed-communication telephone terminal can also establish magneto-telephone communication by connecting to other types of magneto-telephones through the RJ11-11 interface; Ringing and receiving are completed through the ringing current generator and AC bell in the magneto-telephone circuit; Transmitting and receiving are completed through the transmitter and receiver in the telephone handset. When the converter is in the wireless-telephone state, ringing and receiving are completed through the conversion of the transmitting controller and receiving controller; Transmitting and receiving are completed through the microphone and speaker in the telephone handset.

[0062] The working process of the present invention will be described below with reference to the accompanying drawings.

[0063] As Figure 1 shown, the telephone 1 and the telephone 2 are connected through wired transmission media such as paired wires, audio cables, network cables, or twisted pairs to form magneto-telephone communication. When the converter of the telephone is in the magneto-telephone communication position (i.e., pin 3 - pin 1 is connected, pin 4 - pin 2 is connected, pin 9 - pin 7 is connected, pin 10 - pin 8 is connected), when the telephone handset of telephone 1 is picked up and the "ringing switch" of telephone 1 is pressed, the ringing current generator in the magneto-telephone circuit generates an AC ringing current signal of 25 Hz and 60 - 130 V and sends it to the line through the RJ11-6 interface; after the telephone 2 receives the ringing current signal, the bell in the receiving circuit of the magneto-telephone circuit makes a "dingling, dingling" sound; when the telephone handset of telephone 2 is picked up, telephone 1 and telephone 2 can conduct telephone communication through the transmitter and receiver.

[0064] As Figure 2 shown, the telephone 1 and the telephone 2 rely on the shortwave channel to establish wireless telephone communication.

[0065] 1. Transmitting.

[0066] (1) Ringing. When the converter of the telephone is in the wireless telephone communication position (i.e., pin 3 - pin 5 of the converter are connected, pin 4 - pin 6 are connected, pin 9 - pin 11 are connected, pin 10 - pin 12 are connected), when the telephone handset of telephone 1 is picked up and the "ringing switch" of telephone 1 is pressed, the ringing current generator in the magneto telephone circuit generates a ringing current signal. When the transmitting controller receives the ringing current signal (i.e., high - level signal) sent by the telephone, the transmitting controller issues a control signal to control the transmitter to send out the pre - edited Morse telegraph code (such as the Morse telegraph code corresponding to SOS). It is connected to transmitters 1 - 5 through RJ11 - 1, RJ11 - 2, RJ11 - 3, RJ11 - 4, RJ11 - 5 interfaces and is sent through transmitters 1 - 5. The transmitting controller is equivalent to a switch that triggers the transmitter to send out a fixed Morse telegraph code.

[0067] (2) Transmitting speech. The microphone of the telephone can be connected to the voice conversion part of the Morse code transceiver system through the V3.5 - 1 interface, is converted into Morse telegraph code through the Morse code transceiver system, and is sent through the wireless transmitter.

[0068] 2. Receiving.

[0069] (1) Ringing reception. When the code receiver of the Morse code transceiver system receives the fixed Morse telegraph code, it converts the parallel Morse telegraph code into a serial Morse telegraph code and is connected to the RJ11 - 7 interface of the telephone through the audio system; after the receiving controller of the telephone receives the fixed Morse telegraph code, it controls the relay to work and controls the ringing receiver of the magneto telephone circuit to work. The ringing receiver sends a ringing signal to the electric bell, and the electric bell makes a "ding - ling, ding - ling" sound.

[0070] (2) Receiving speech. When the Morse code transceiver system (code receiver) receives the Morse telegraph code, it converts the parallel Morse telegraph code into a serial Morse telegraph code and is connected to the V3.5 - 2 interface of the telephone through the audio system, and sends the voice to the speaker.

[0071] The said Morse code transceiver system includes a code - transmitting system and a code - receiving system. The code - transmitting system includes a code - transmitting input part and a Morse code transmitter. The signal output port of the code - transmitting input part is connected to the control signal input port of the transmitter.

[0072] The code - receiving system includes a Morse code receiver and a code - receiving output part. The output port of the receiver is connected to the input port of the code - receiving output part.

[0073] The transmitter transmits information to the receiver through a relay channel.

[0074] Through the cooperation of each part, the Morse code transceiver system of the present invention facilitates the sending and receiving of Morse code.

[0075] The control signal output port of the code sending input part is connected to the control signal input port of the Morse code sender through a serial port.

[0076] The relay channel adopts a wired relay channel or a wireless relay channel.

[0077] The code sending input part and the code receiving output part adopt a computer. Input can be through the computer microphone. The computer converts the voice signal into digital information (the voice signal can be converted into Chinese characters through Baidu Voice Assistant or iFlytek Voice Recognition, and then the Chinese characters are converted into numbers) and sends it to the code sender. The code sender converts the numbers into Morse code and sends it out (converting numbers into Morse code is a conventional technology and is converted according to the existing number and Morse code conversion table). It is also possible to input Chinese characters through the computer keyboard, and the computer converts the Chinese characters into digital information and sends it to the code sender.

[0078] The computer in the code receiving output part can convert the received numbers into Chinese characters and voice (Baidu Voice Assistant or iFlytek Voice Recognition), and display them on the computer monitor and output them through the audio system.

[0079] The Morse code transceiver system of the present invention sends telegraph codes in parallel ( Figure 5 the five-way audio transceiver channels in the middle), that is, one telegraph code is sent at a time. The traditional way of sending Morse telegraph codes is in serial mode, and the elements of the telegraph code need to be sent one by one. For example, the telegraph code of the Arabic numeral "3" consists of 5 elements: "dot", "dot", "dot", "dash", "dash". Using the serial sending method, it takes 5 times to complete the sending of the telegraph code of the number "3". While using the parallel method to send the number "3", 5 elements are sent simultaneously at one time, and the sending of the number "3" can be completed at one time. Compared with the serial method, the biggest advantage of the parallel method is that it takes less time and can increase the telegraph sending speed by at least more than 8 times.

[0080] The Morse code transceiver system of the present invention has good security performance. When using the parallel method to send telegraph codes, 5 different frequencies are used when using wireless communication, and 5 audio relay circuits (bandwidth 64K) are used when using wired communication. If the serial sending method is used, the process of sending the telegraph code can be mastered on 1 frequency (or 1 audio relay circuit). While using the parallel sending method, the process of sending the telegraph code needs to be mastered on 5 frequencies (or 5 audio relay circuits) simultaneously.

[0081] One type of the code receiving output system can automatically convert the received Morse code into voice (through a voice synthesizer); another type can automatically convert the received Morse code into Chinese characters.

[0083] The code sender includes a first output port, a second output port, a third output port, a fourth output port, and a fifth output port.

[0084] The first output port outputs the first element of the telegraph code, the second output port outputs the second element of the telegraph code, the third output port outputs the third element of the telegraph code, the fourth output port outputs the fourth element of the telegraph code, and the fifth output port outputs the fifth element of the telegraph code. When the Morse telegraph code has less than 5 digits, there will be as many output channels as there are digits. For example, the Morse telegraph code for the Arabic numeral "2" is one "dot" and one "dash", that is, there are 2 elements. At this time, the first output of the code sender is "dot", the second output is "dash", and the third to fifth outputs are none.

[0085] The code sender uses a parallel output method to complete the Morse code sending. When using a wireless communication method, 5 sets of transceivers are required, and each transmitter uses one frequency. When using a wired communication method, 5 digital audio relay circuits are required, and a 64K circuit of the optical fiber communication network can be used as the signal transmission relay.

[0103] The audio signal distribution part uses two NE5532 chips to distribute the audio signal into five paths. The voice conversion processing part uses five Cortex-A53 chips to respectively receive the five-way audio distribution signals.

[0104] The voice conversion part of the present invention changes the single-channel speech recognition to multi-channel probabilistic speech recognition.

[0105] The voice conversion part of the present invention divides 1-way user voice into 5-way voices (the audio signal distribution part divides 1-way user voice into 5-way voices), compares and discriminates the 5-way voices respectively, and takes the voice with the highest same probability as the correct voice. By adopting this voice recognition method, the voice recognition probability can be further improved, and the recognition accuracy rate can reach 90% - 100%. When the comparison probability of a group of Chinese characters is 100%, it means that the 5-way Chinese character groups are the same, and the translation of this group of Chinese characters is correct; when the comparison probability of a group of Chinese characters is 80%, it means that 4-way Chinese character groups are the same and 1-way Chinese character group translation is different, then the translation of the Chinese character group with a higher probability is correct (for the software of voice to Chinese characters and Chinese characters to voice, Baidu Voice Assistant or iFlytek Speech Recognition can be used). See the following table for details.

[0106]

[0107]

[0108] It can be seen from the above table that there are 7 situations for discriminating the Chinese character groups with a high probability to be correct. When the discrimination probability of the Chinese character group is 100%, the system outputs the correct Chinese character group with a 100% probability; when the discrimination probability of the Chinese character group is 80%, the system outputs the correct Chinese character group with an 80% probability; when the discrimination probability of the Chinese character group is 60%, the system outputs the correct Chinese character group with a 60% probability; when the discrimination probabilities of the Chinese character group are 40%, 20%, 20%, 20% respectively, the system outputs the correct Chinese character group with a 40% probability; when the discrimination probabilities of the Chinese character group are 40%, 40%, 20% respectively, the system cannot judge the correct Chinese character group, so no correct Chinese character group is output; when the discrimination probabilities of the Chinese character group are 20%, 20%, 20%, 20%, 20% respectively, the system cannot judge the correct Chinese character group, so no correct Chinese character group is output.

[0109] The voice conversion part of the present invention has a high probability of correctly recognizing Chinese character groups.

[0110] For a single-way voice translation system, it takes long-term training by users to achieve a certain degree of correct translation. When a new voice translation program starts to be used, the correct recognition rate can only reach about 60%. After a period of training or longer training by users, the correct recognition of the voice translation program will continuously improve, but the highest can only reach about 90%. Once there is a translation error, it cannot be recovered. The present invention adopts 5-way translation. Based on the 90% correct rate of the 5-way translation, it conducts a high-probability statistics on the 5-way voice translations, and the correct recognition rate is definitely higher than that of the single-way, and the highest can reach 90% - 100%.

[0111] The voice conversion part of the present invention has high reliability.

[0112] Since the voice recognizer designed by the present invention adopts 5-channel voice translation, the voice translation of a certain channel only accounts for 20% of the voice recognizer. That is to say, when there is a deviation in the voice translation of a certain channel, it will not affect the overall voice translation of the voice recognizer of the present invention. If selected according to the correct Chinese character group probability of 60%, the present invention allows one or two channels to have translation deviations. In this regard, the reliability of this system is increased by at least 40%.

[0113] The voice conversion part of the present invention is conveniently connected.

[0114] Since the present invention adopts two interfaces, namely the standard network port and V3.5, the connection between each device is convenient and simple. The V3.5 port is connected to the user voice collector, and the other end of the V3.5 port is connected to the amplification part.

[0115] After the user inputs the voice, through the amplification part and the audio signal distribution part, 1-channel user voice is divided into 5-channel voices, and the 5-channel audio signals are connected to 5 microprocessors. Each microprocessor converts the 5-channel audio signals into 5-channel Chinese character groups (using Baidu Voice Assistant or iFlytek Voice Recognition Software), Figure 11 The Cortex-A53 chip M6 in the above table can judge the 5-channel Chinese character groups, and can confirm the Chinese character groups with probabilities of 100%, 80% and 60% as correct Chinese character groups; when the probability is 40% and the probabilities of the other 3 groups are all 20%, the Chinese character group with 40% can be confirmed as the correct Chinese character group; when there are 2 groups of Chinese character groups with a probability of 40%, it is impossible to identify which group is the correct Chinese character group, so the output Chinese character group is not confirmed; when there are 5 groups of Chinese character groups with a probability of 20% each, it is impossible to identify which group is the correct Chinese character group, so the output Chinese character group is not confirmed. After M6 judges the 5-channel Chinese character groups, the result is output through the network switch.

[0116] The voice conversion part of the present invention divides 1-channel user voice into multiple channels of voices through the audio signal distribution part, so that each channel of voice can be converted into Chinese characters through the voice conversion processing part, which is convenient for comparing the correctness of the voices and can improve the accuracy of voice recognition.

Those of ordinary skill in the art should understand that the present invention can still be modified or equivalently replaced to achieve the same technical effects; as long as it meets the usage requirements, it is within the protection scope of the present invention.
