[0052] First embodiment:
[0053] Please combine Figures 1 to 4 , Figure 6 and Figure 7 , a special post language communication system, comprising a central console 1 and a headset 2;
[0054] The earphone 2 comprises a stabilizing bar 21, both ends of which are fixed with a backup battery 22 and a housing 3, the side walls of the backup battery 22 and the housing 3 are fixed with ear hanging bars 23, and the outer walls of the two ear hanging bars 23 are both installed with a listening component 4;
[0055] The outer walls of the two listening components 4 are fixed with protective covers 24, and the outsides of the two protective covers 24 are installed with noise reduction components 5;
[0056] The listening component 4 comprises a mounting shell 41, an inner shell 43 is embedded in the mounting shell 41, a bone conduction diaphragm 42 is embedded in the inner shell 43, a slot 44 is formed on the outer wall of the inner shell 43, a return spring 45 is sleeved inside the slot 44, a slider 46 is slidably connected inside the inner shell 43 and located on one side of the slot 44, and a rubber ring 47 is fixed on the outer wall of the slider 46;
[0057] See also Figure 2 When in use, the staff of special posts need to put the stabilizing bar 21 on the back of the head, and then hang the two ear hanging bars 23 on the ears, so that the listening component 4 can be firmly attached to the two sides of the skull.
[0058] See also Figure 3 and Figure 4When the listening component 4 is fitted on both sides of the skull, the outer edge of the rubber ring 47 is the first to fit with both sides of the skull, and the rubber ring 47 can freely control the slider 46 to slide in the slot 44 of the inner shell 43 according to the size of the staff's head circumference, and the reaction force will control the return spring 45 to be compressed during the movement, and when the rubber ring 47 moves to the extreme fitting position, the bone conduction diaphragm 42 inside the inner shell 43 will fit stably and closely with both sides of the staff's skull.
[0059] The housing 3 includes a battery 31, the battery 31 is electrically connected to a processor 32 through a wire, the processor 32 is electrically connected to a radio transmitter 35, a radio receiver 34 and a built-in earphone 33 through a wire, the built-in earphone 33 is electrically connected to a filter module 11 through a wire, the filter module 11 is electrically connected to an oscilloscope 12 through a wire, the oscilloscope 12 is electrically connected to a selection module 13 through a wire, and the battery 31 is electrically connected to a switch 36 through a wire;
[0060] The center console 1 is provided with a transceiver / receiver antenna 14 and a transceiver bandpass filter 15 inside, and the center console 1 is electrically connected to an explosion-proof speaker 8 outside via a wire.
[0061] See also Figure 6 : When used by special post staff, they need to press the power button 36 to start the entire headset 2. The battery 31 and the backup battery 22 are used to supply power to all components inside the headset 2. The staff can speak directly after wearing it, and the sound will be transmitted to the processor 32 through the built-in earphone 33. The processor 32 recognizes and integrates it, and then transmits the corresponding frequency radio to the central console 1 through the radio transmitter 35. The frequency is received by the receive / transmit antenna 14.
[0062] See also Figure 7 : The sound frequency transmitted from the built-in headset 33 will first pass through the filter module 11, and then the sound wave frequency will be displayed through the oscilloscope 12. The user can observe the waveform on the oscilloscope 12 to determine the sound wave pattern of the staff member. The staff in the safety zone needs to operate the selection module 13 to control the oscilloscope 12 to only take the sound frequency of the special post personnel, and eliminate other noises on the scene (using digital filtering to filter the voice signal to remove the noise within a specific frequency range. Commonly used filters include low-pass filtering, high-pass filtering and band-pass filtering, etc. These filtering devices can be designed and adjusted according to the spectral characteristics of the noise) (by analyzing the spectrum of the voice signal, comparing the noise spectrum with the voice spectrum, and then subtracting the noise spectrum to restore a clear voice signal. Commonly used spectral subtraction algorithms include short-time Fourier transform (STFT) and minimum mean square error estimation (MMSE)).
[0063] After selection, the voice of the special post staff will be amplified by audio and then passed through the modulation circuit, and finally a series of high-frequency amplification processes will be performed to enter the central console 1, and finally through the transceiver bandpass filter 15 after frequency selection amplification, mixing circuit, intermediate amplifier circuit and audio amplification. Finally, the user can listen to the language of the special post staff from the sound emitted by the explosion-proof speaker 8.
[0064] The outer walls of the stabilizing bar 21 and the two ear hanging bars 23 are respectively coated with liquid silicone, and the rubber ring 47 is made of silicone material. The front end of the rubber ring 47 is in an arc shape, and the outer wall of the rubber ring 47 is fixedly connected to the reset spring 45.
[0065] See also Figure 2 The liquid silicone coating process can ensure that the back of the head and the ear position of the special post staff and the contact between the stabilizing strip 21 and the ear hanging strip 23 are more comfortable, and at the same time can also effectively isolate sweat.
[0066] The bone conduction diaphragm 42, the battery 31 and the processor 32 are electrically connected in series, the bone conduction diaphragm 42, the switch key 36 and the battery 31 are electrically connected in parallel, the built-in earphone 33, the radio transmitter 35, the radio receiver 34 and the processor 32 are connected in series, and the transmit / receive antenna 14 and the transmit / receive bandpass filter 15 are interconnected.
[0067] The built-in headset 33, the filter module 11, the oscilloscope 12, the selection module 13 and the central console 1 are electrically connected in series.
[0068] This embodiment: Compared with the traditional language communication design, this case is designed with two bone conduction diaphragms 42 to fit with the two sides of the staff's skull, and an elastically movable rubber ring 47 is arranged on the outside of the bone conduction diaphragm 42, so that the staff first touches the rubber ring 47 before the bone conduction diaphragm 42 fits, and the rubber ring 47 can also be adaptively adjusted according to the staff with different head circumferences. Therefore, such a design not only has high sensitivity and can clearly hear the sound, but also has an excellent filtering effect on environmental noise. In complex special positions, bone conduction can provide users with a clear and pure voice communication experience, and at the same time it also has a good isolation effect, can be waterproof and dustproof, and increase the service life of the bone conduction diaphragm 42. At the same time, voice narrow-band filtering technology is adopted. This technology can set a narrower frequency response range filtering according to the frequency characteristics of human language. Through narrow-band filtering, the interference of environmental noise is eliminated to a great extent. Whether in a noisy industrial site or in a high-noise environment, the voice carrier frequency filtering technology can provide users with a clear and pure voice communication experience.
[0069] Second embodiment:
[0070] See also Figure 3 , Figure 6 and Figure 8 The outer wall of the installation shell 41 is fixedly provided with a protective cover 24, the interior of the protective cover 24 is provided with a connecting wire 53, the output end of the connecting wire 53 is electrically connected to a player 52, and the outer wall of the player 52 is provided with an earplug 51;
[0071] Preferably, the earplug 51 may be made of memory foam.
[0072] See also Figure 3 During use of the first embodiment, special post staff need to insert the earplug 51 into the ear canal, and the earplug 51 is made of memory foam, which can adaptively deform according to different ear canals to fit the ear canal.
[0073] The center console 1 is also provided with a power supply 16, the transceiver bandpass filter 15 is electrically connected to an explosion-proof microphone 9 via a wire, the battery 31 is electrically connected to an FM knob 37 via a wire, the FM knob 37 is electrically connected to a frequency selection module 38 via a wire, and the battery 31 is electrically connected to a player 52 via a wire;
[0074] See also Figure 6 and Figure 7 : In the process of the first embodiment, when the staff in the safety zone hears the voice of the staff in the special post, the staff in the safety zone can speak through the explosion-proof microphone 9, and the sound is amplified at high frequency and enters the transceiver bandpass filter 15 to transmit the frequency to the radio receiving end 34 in the housing 3 through the transceiver antenna 14, and the processor 32 conducts the sound wave frequency to the bone conduction diaphragm 42. The bone conduction diaphragm 42 attached to both sides of the skull vibrates the skull and conducts the frequency to the auditory nerve, so that the staff in the special post can hear the communication voice of the staff in the safety zone;
[0075] The intercom 10 can be connected to the receiving / transmitting antenna 14 in the center console 1 by radio. When used by special post personnel, they can rotate the frequency tuning knob 37. When it is rotated to the corresponding channel, the frequency selection module 38 will select the corresponding frequency and transmit the signal to the processor 32. The processor 32 performs specific frequency recognition to the corresponding frequency and establishes a radio connection with the corresponding intercom 10, so that multi-channel switching can be selected for use.
[0076] A plurality of intercoms 10 are also placed on the upper surface of the center console 1, and the player 52 includes a recording module 521, the recording module 521 is electrically connected to a frequency division module 522 via a wire, the frequency division module 522 is electrically connected to a processing module 523 via a wire, the processing module 523 is electrically connected to a sound amplification module 524 and a muffler module 525 via a wire, and the sound amplification module 524 is electrically connected to a playback speaker 526 via a wire.
[0077] An electrical path is formed between the battery 31, the processor 32, the FM knob 37 and the frequency selection module 38; the bone conduction diaphragm 42, the player 52 and the battery 31 are connected in parallel; the transceiver bandpass filter 15, the explosion-proof microphone 9 and the explosion-proof speaker 8 are connected in parallel; the sound amplification module 524, the muffler module 525 and the processing module 523 are connected in parallel; the recording module 521, the frequency division module 522, the processing module 523, the sound amplification module 524 and the playback speaker 526 are connected in series.
[0078] See also Figure 8 : After putting on the earplugs 51, the special personnel will hear sounds. At this time, both the ambient noise and the voice of the staff will be transmitted to the frequency division module 522 through the recording module 521, and then the corresponding human voice and ambient noise will be partitioned and identified through the processing module 523. The identified human voice frequency and ambient noise frequency will pass through the two channels in turn through the amplification module 524 and the silencer module 525 respectively. The voice of the staff themselves will be silenced, and the ambient noise will be amplified and finally transmitted to the ears of the staff through the playback speaker 526.
[0079] This embodiment: This system can perform frequency division switching and noise reduction processing. The frequency division supports multi-person intercom function. Through the cooperation between the command console and three terminal users, simultaneous intercom can be realized. Under this function, you can speak freely without waiting for the response of others. This instant communication method helps to solve communication problems in team collaboration and improve work efficiency. Whether in emergency situations or in daily work, the multi-person intercom function can provide timely and efficient communication support for the team;
[0080] When special post staff are speaking, the noise reduction function can make the staff unable to hear their own voices. This function is based on advanced digital signal processing technology. By processing the collected sounds, it can suppress their own voices. In this way, the staff will not hear their own echoes or other noises when speaking, and can focus more on communicating with others. This function not only improves communication efficiency, but also reduces your fatigue. At the same time, in order to ensure the working safety of the on-site environment, the ambient sound will be appropriately amplified, so that the on-site staff can respond to abnormal sounds or alarms in time, thereby increasing the safety of the staff.
[0081] Third embodiment:
[0082] See also Figure 2 , Figures 5 to 9 The positioning component 7 includes a pressure sensor 71, the pressure sensor 71 is electrically connected to a signal detector 72 through a wire, the signal detector 72 is electrically connected to a main locator 73 and a photosensitive sensor 74 through a wire, the photosensitive sensor 74 is electrically connected to a control terminal 75 through a wire, and the control terminal 75 is electrically connected to a third-party locator 76 through a wire.
[0083] See also Figure 2 and Figure 5 : During the use of the first embodiment and the second embodiment, if the headset is used in a very dangerous environment, the user needs to connect the entire headset 2 and the helmet to prevent loss;
[0084] Pass the anti-lost belt 25 through the inner belt of the safety helmet, and then align the detachable block 61 and the sleeve 62. After the alignment is completed, insert the detachable block 61 along the horizontal direction of the sleeve 62. When the card plate 64 inside the detachable block 61 enters the position of the card tooth 66, since the card tooth 66 is a forward tooth structure, the engaging groove 65 will engage with the card tooth 66 along the forward tooth direction of the card tooth 66 during the pushing process. During the engagement process, the engaging spring 63 will elastically move to keep the card plate 64 and the card tooth 66 stably connected.
[0085] The pressure sensor 71, the signal detector 72, the photosensor 74, the control terminal 75 and the third-party locator 76 are connected in series, and the main locator 73, the pressure sensor 71 and the signal detector 72 are connected in parallel.
[0086] See also Fig. 9 : When the pressure sensor 71 inside the sleeve 62 is subjected to the moving pressure of the detachable block 61, the pressure sensor 71 will start the signal detector 72 to work. When the signal detector 72 is working, the internal signal indicator light will light up. When the signal detector 72 has a normal strong signal, it will only control the main positioner 73 to locate the position;
[0087] It can be seen that the front end photosensitive head of the photosensor 74 extends to the third signal indicator light of the signal detector 72. However, when the position signal changes, if the indicator light goes out at the third grid, the photosensor 74 generates a photosensitivity disappearance signal, which will drive the control terminal 75 to start controlling the positioning work of the third-party locator 76 (the third-party locator can use other satellite terminals such as GPS).
[0088] In this embodiment, a snap-fit component 6 and a positioning component 7 are provided, and the earphone 2 and the helmet can be connected together by a unidirectional snap-fit method. This not only has the function of quick release, but also has the function of anti-lost. At the same time, the positioning component 7 can be started after the snap-fit component 6 is installed. The positioning component 7 is divided into two position positioning functions. If the signal in the on-site environment is unstable, the dual-channel position positioning can be started, which can ensure that the position information of the staff can be accurately displayed at all times.
[0089] Please refer to Figures 1 to 9 The working principle of a special post language communication system provided by the present invention is as follows:
[0090] Step S1: The method for special post staff to wear the earphone 2 is as follows:
[0091] Staff members in special positions need to put the stabilizing bar 21 on the back of the head, and then hang the two ear-hanging bars 23 on the ears, so that the listening component 4 can fit stably on both sides of the skull. When the listening component 4 fits on both sides of the skull, the outer edge of the rubber ring 47 is the first to fit with both sides of the skull, and the rubber ring 47 can freely control the slider 46 to slide in the slot 44 of the inner shell 43 according to the size of the staff member's head circumference, and the reaction force will control the return spring 45 to be compressed during the movement, and when the rubber ring 47 moves to the extreme fitting position, the bone conduction diaphragm 42 inside the inner shell 43 will fit stably and closely with both sides of the staff member's skull.
[0092] Step S2: The dialogue method is as follows:
[0093] After wearing it, the staff can speak directly, and the sound will be transmitted to the processor 32 through the built-in earphone 33. The processor 32 will identify and integrate it, and then transmit the corresponding frequency to the central console 1 through the radio transmitter 35. The frequency is received by the receiving / transmitting antenna 14. After selection, the voice of the special post staff will be amplified by audio and then pass through the modulation circuit, and finally undergo a series of high-frequency amplification processes to enter the central console 1. Finally, it will pass through the transceiver bandpass filter 15, undergo frequency selection amplification, mixing circuit, intermediate amplifier circuit and audio amplification. Finally, the user can listen to the language of the special post staff from the sound emitted by the explosion-proof speaker 8;
[0094] The staff in the safety zone can speak through the explosion-proof microphone 9. The sound is amplified at high frequency and enters the transceiver bandpass filter 15, and the frequency is transmitted to the radio receiving end 34 in the housing 3 through the transceiver antenna 14. The processor 32 transmits the sound wave frequency to the bone conduction diaphragm 42. The bone conduction diaphragm 42 attached to both sides of the skull vibrates the skull and transmits the frequency to the auditory nerve, so that the special post staff can hear the communication voices of the staff in the safety zone.
[0095] Step S4: The noise reduction method is as follows:
[0096] After putting on the earplugs 51, the special personnel will hear sounds. At this time, both the ambient noise and the voice of the staff will be transmitted to the frequency division module 522 through the recording module 521, and then the corresponding human voice and ambient noise will be partitioned and identified through the processing module 523. The identified human voice frequency and ambient noise frequency will pass through the two channels in turn through the amplification module 524 and the mute module 525 respectively. The voice of the staff themselves will be mute-processed, and the ambient noise will be amplified and finally transmitted to the ears of the staff through the playback speaker 526.
