Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and more specifically to a maintenance system based on wireless communication equipment. Background Technology

[0002] Wireless communication devices are mobile devices that provide the means for remote interaction.

[0003] A walkie-talkie is a type of wireless communication device.

[0004] However, walkie-talkies are currently subject to various forms of communication interference while providing communication services to users. These interferences directly affect the quality of the communication audio, resulting in poor communication interaction and preventing both parties from quickly and accurately obtaining the information to be transmitted through the communication audio. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a maintenance system based on wireless communication equipment, which solves the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A maintenance system based on wireless communication equipment includes a monitoring layer, a conversion layer, and an interaction layer;

[0008] The real-time communication status parameters of the communication device are collected by the monitoring layer. The monitoring layer analyzes the stability of the communication status of the communication device based on the collected communication status parameters. The conversion layer receives the communication status stability of the communication device analyzed by the monitoring layer. Based on the stability of the communication status of the communication device, it decides whether to convert the audio data to be transmitted by the communication device. When the conversion layer converts the audio data, the interaction layer is triggered to run synchronously after the conversion is completed. The converted audio data is sent to the receiving target communication device. After receiving the converted audio data, the receiving target communication device restores the converted audio data to the original audio data format in real time for the user to listen to.

[0009] The conversion layer includes a setting module, a preprocessing module, and a conversion module. The setting module is used to set a communication status stability judgment threshold, receive the communication status stability of the communication device analyzed in the monitoring layer, and determine whether the communication status of the communication device is stable based on the comparison between the communication status stability judgment threshold and the communication status stability of the communication device. The preprocessing module is used to receive the judgment result in the setting module. When the judgment result is negative, it obtains the audio data to be transmitted in the communication device and performs noise reduction processing on the audio data. The conversion module is used to receive the audio data after noise reduction processing in the preprocessing module and extract text from the audio data.

[0010] The noise-reduced audio data in the preprocessing module is output using the following formula:

[0011]

[0012] In the formula: H is the audio data after noise reduction; G is the gain factor; K is the number of sample points in a frame of audio data, i.e., the frame length; k is the sample point sequence; s is the noisy speech stream; L is the displacement of each frame; c represents windowing processing; p is the total number of sample points in the noisy speech stream; g is the g-th sample point in the m-th frame.

[0013] During the preprocessing module's operation, the size of the audio data is identified synchronously. The larger the audio data, the more times the preprocessing module performs noise reduction processing on the audio data; conversely, the smaller the audio data, the fewer times the preprocessing module performs noise reduction processing on the audio data. The number of times the preprocessing module performs noise reduction processing on the audio data ranges from 1 to 4.

[0014] Furthermore, the monitoring layer includes a data acquisition module, an analysis module, and an evaluation module. The data acquisition module is used to acquire network status parameters of the communication device connecting to the communication network in real time. The analysis module is used to receive the network status parameters acquired by the data acquisition module and analyze the instantaneous stability of the communication network status based on the network status parameters. The evaluation module is used to acquire the instantaneous stability of the communication network status analyzed by the analysis module in real time and evaluate the stability of the communication network status based on the continuously acquired instantaneous stability of the communication network status.

[0015] The acquisition module collects network status parameters of the communication device connected to the communication network, i.e., communication status parameters. The evaluation module evaluates the stability of the communication network status, i.e., communication status stability. During the operation of the acquisition module, the network status parameters of the communication device connected to the communication network are collected in real time based on a set frequency. The set frequency range is 1s / time to 2s / time. After the communication device receives audio data, the analysis module receives network status parameters before transmitting it to the target communication device. The received network status parameters are no less than three sets of network status parameters collected at the set frequency.

[0016] Furthermore, the instantaneous stability analysis logic of the communication network state in the analysis module is expressed as follows:

[0017]

[0018] In the formula: fix(α) is the instantaneous stability performance value of the communication network; f e d0 is the carrier frequency of the communication network; d0 is the reference distance for free space path transmission loss; c is the speed of light. This represents the probability of a Loss of Source (LoS) link in a communication network. Channel fading modeling is performed for LosS links and non-line-of-sight links in communication networks, respectively.

[0019] Among them, the signal fading modeling Represented as n Los n NLos These are the path loss factors for Loss of Source (LoS) links and non-line-of-sight (NOS) links in a communication network, respectively; d in,out η is the distance between two sets of communication devices communicating with each other. Los η NLos These represent shadow fading in the LoS link and non-line-of-sight link of the communication network, respectively. The larger the instantaneous stability performance value fix(α) of the communication network state, the worse the instantaneous stability of the communication network state, and vice versa. Based on the above formula, the instantaneous stability performance value fix(α) of the communication network state is obtained for each set of network state parameters received by the analysis module. The applied parameter in the formula is the network state parameter.

[0020] Furthermore, the stability assessment result of the communication network state in the assessment module is obtained by the following formula:

[0021]

[0022] In the formula: Let be the state stability performance value of the communication network; n is the set of instantaneous state stability performance values ​​of the communication network obtained; fix(α) i Let be the instantaneous stability performance value of the i-th group of communication network states; n0 is the total number of instantaneous stability performance values ​​of the n-th group of communication network states;

[0023] Among them, the instantaneous stability values ​​of the communication network state corresponding to i and (1,2,3,...,x-2,x-1,x) are all derived from n.

[0024] Furthermore, the windowing process 'c' used in the noise reduction output formula of the preprocessing module is a Hanning window.

[0025] Furthermore, the conversion module is integrated with a speech recognition module, and the format conversion operation performed on the audio data in the interaction layer is the operation of the speech recognition module in the conversion module to extract text from the audio data;

[0026] The audio data after format conversion is the text data extracted from the audio data in the conversion module.

[0027] Furthermore, when the conversion module in the conversion layer finishes running, it synchronously feeds back the text extracted from the audio data to the interaction layer, and simultaneously triggers the monitoring layer to run again. It further feeds back the stability of the communication status of the communication device analyzed by the monitoring layer to the conversion layer, and the setting module in the conversion layer continuously determines whether the communication status of the communication device is stable.

[0028] In the monitoring layer, when the device is triggered to run again, the conversion layer continuously determines whether the communication status of the communication device is stable. If the determination result is yes, the device is controlled to return to the audio data interaction state. Otherwise, the conversion layer continuously extracts text from the audio data and transmits it to the interaction layer, which then controls the interaction of the communication device.

[0029] Furthermore, the interaction layer includes a transmission module, a reading module, and a feedback module. The transmission module is used to receive text data extracted from audio data by the conversion module in the conversion layer, convert the text data into digital signals, and transmit the converted text data to the receiving target communication device from the communication device corresponding to the audio data. The reading module is used to receive the converted text data, restore the digital signals to text data, and perform voice broadcasting on the text data. The feedback module is used to record the usage rate of the system's interaction layer in real time.

[0030] During the transmission module's operation phase, the two sets of communication devices that perform the interaction reject the audio data input operation of the user held by the communication device. During the reading module's operation phase, the target communication device rejects the audio data input operation of the user held by the communication device.

[0031] Furthermore, the interaction layer usage rate recorded in the feedback module is the ratio of the number of times the reading module runs to the number of audio interactions during the interaction operation performed by the communication device.

[0032] Furthermore, the setting module is interconnected with a preprocessing module and a conversion module via a wireless network; the conversion module is interconnected with an evaluation module via a wireless network; the evaluation module is interconnected with an analysis module and a data acquisition module via a wireless network; the setting module is interconnected with a transmission module via a wireless network; and the transmission module is interconnected with a reading module and a feedback module via a wireless network.

[0033] Compared with known public technologies, the technical solution provided by this invention has the following beneficial effects:

[0034] 1. This invention provides a maintenance system based on wireless communication equipment. This system is applied to walkie-talkie-type communication equipment, avoiding traditional communication modes. When communication conditions are poor, it can intelligently convert communication audio data into text data for transmission, which greatly reduces the demand for communication signal strength and communication network when communication conditions are poor, making the information transmission process of the communication equipment equipped by this system more stable.

[0035] 2. In the present invention, during the operation of the system, the stability of the communication network can be calculated using specified analysis logic, and then the system can be provided with operational logic support based on the stability calculation results. At the same time, the communication process of the communication device can intelligently and autonomously complete the real-time switching of communication logic to ensure the stability of the communication process of the communication device.

[0036] 3. During system operation, the present invention can perform noise reduction processing on the audio data to be transmitted by the communication device, thereby improving the quality of the communication audio transmitted by the communication device, bringing a better communication experience to the users of the communication device, and through the noise reduction processing of the communication audio, it can provide further data support for text extraction, making the transmission of communication information more accurate under poor communication conditions, and providing a stable guarantee for the transmission of communication information.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] The present invention will be further described below with reference to embodiments.

[0042] Example 1

[0043] This embodiment provides a maintenance system based on wireless communication equipment, such as... Figure 1 As shown, it includes a monitoring layer, a conversion layer, and an interaction layer;

[0044] The real-time communication status parameters of the communication device are collected by the monitoring layer. The monitoring layer analyzes the stability of the communication status of the communication device based on the collected communication status parameters. The conversion layer receives the communication status stability of the communication device analyzed by the monitoring layer. Based on the stability of the communication status of the communication device, it decides whether to convert the audio data to be transmitted by the communication device. When the conversion layer converts the audio data, the interaction layer is triggered to run synchronously after the conversion is completed. The converted audio data is sent to the receiving target communication device. After receiving the converted audio data, the receiving target communication device restores the converted audio data to the original audio data format in real time for the user to listen to.

[0045] The monitoring layer includes an acquisition module, an analysis module, and an evaluation module. The acquisition module is used to acquire network status parameters of the communication device connected to the communication network in real time. The analysis module is used to receive the network status parameters acquired by the acquisition module and analyze the instantaneous stability of the communication network based on the network status parameters. The evaluation module is used to acquire the instantaneous stability of the communication network analyzed by the analysis module in real time and evaluate the stability of the communication network based on the continuously acquired instantaneous stability of the communication network.

[0046] Among them, the network status parameters of the communication device connected to the communication network collected in the acquisition module are called communication status parameters, and the stability of the communication network status evaluated in the evaluation module is called communication status stability. During the operation of the acquisition module, the network status parameters of the communication device connected to the communication network are collected in real time based on a set frequency. The set frequency range is 1s / time to 2s / time. After the communication device receives the audio data, the analysis module receives the network status parameters before transmitting it to the target communication device. The received network status parameters are no less than three sets of network status parameters collected at the set frequency.

[0047] The instantaneous stability analysis logic of the communication network state in the analysis module is represented as follows:

[0048]

[0049] In the formula: fix(α) is the instantaneous stability performance value of the communication network; f e d0 is the carrier frequency of the communication network; d0 is the reference distance for free space path transmission loss; c is the speed of light. This represents the probability of a Loss of Source (LoS) link in a communication network. Channel fading modeling is performed for LosS links and non-line-of-sight links in communication networks, respectively.

[0050] Among them, signal fading modeling Represented as n Los n NLos These are the path loss factors for Loss of Source (LoS) links and non-line-of-sight (NOS) links in a communication network, respectively; d in,out η is the distance between two sets of communication devices communicating with each other. Los η NLos These represent the shadow fading of the Loss of Source (LoS) link and the non-line-of-sight (NOS) link in the communication network, respectively. The larger the instantaneous stability performance value fix(α) of the communication network state, the worse the instantaneous stability of the communication network state, and vice versa. Based on the above formula, the instantaneous stability performance value fix(α) of the communication network state is obtained for each set of network state parameters received by the analysis module. The applied parameter in the formula is the network state parameter.

[0051] The stability assessment result of the communication network in the evaluation module is obtained by the following formula:

[0052]

[0053] In the formula: Let be the state stability performance value of the communication network; n is the set of instantaneous state stability performance values ​​of the communication network obtained; fix(α) i Let be the instantaneous stability performance value of the i-th group of communication network states; n0 is the total number of instantaneous stability performance values ​​of the n-th group of communication network states;

[0054] Among them, the instantaneous stability values ​​of the communication network state corresponding to i and (1,2,3,...,x-2,x-1,x) are all derived from n;

[0055] The conversion layer includes a setting module, a preprocessing module, and a conversion module. The setting module is used to set the communication status stability judgment threshold, receive the communication status stability of the communication device analyzed in the monitoring layer, and determine whether the communication status of the communication device is stable based on the comparison between the communication status stability judgment threshold and the communication status stability of the communication device. The preprocessing module is used to receive the judgment result in the setting module. When the judgment result is negative, it obtains the audio data to be transmitted in the communication device and performs noise reduction processing on the audio data. The conversion module is used to receive the audio data after noise reduction processing in the preprocessing module and extract text from the audio data.

[0056] The audio data after noise reduction in the preprocessing module is output using the following formula:

[0057]

[0058] In the formula: H is the audio data after noise reduction; G is the gain factor; K is the number of sample points in a frame of audio data, i.e., the frame length; k is the sample point sequence; s is the noisy speech stream; L is the displacement of each frame; c represents windowing processing; p is the total number of sample points in the noisy speech stream; g is the g-th sample point in the m-th frame.

[0059] During the preprocessing module's operation, the size of the audio data is identified synchronously. The larger the audio data, the more times the preprocessing module performs noise reduction processing on the audio data; conversely, the smaller the audio data, the fewer times the preprocessing module performs noise reduction processing on the audio data. The number of times the preprocessing module performs noise reduction processing on the audio data is 1 to 4.

[0060] The interaction layer includes a transmission module, a reading module, and a feedback module. The transmission module is used to receive text data extracted from audio data by the conversion module in the conversion layer, convert the text data into digital signals, and transmit the converted text data to the receiving target communication device from the communication device corresponding to the audio data. The reading module is used to receive the converted text data, restore the digital signals to text data, and perform voice broadcasting of the text data. The feedback module is used to record the usage rate of the system's interaction layer in real time.

[0061] During the transmission module's operation phase, the two sets of communication devices that perform the interaction reject the audio data input operation of the user held by the communication device. During the reading module's operation phase, the target communication device rejects the audio data input operation of the user held by the communication device.

[0062] The setting module has a preprocessing module and a conversion module that are interconnected via a wireless network. The conversion module has an evaluation module that is interconnected via a wireless network. The evaluation module has an analysis module and a data acquisition module that are interconnected via a wireless network. The setting module has a transmission module that is interconnected via a wireless network. The transmission module has a reading module and a feedback module that are interconnected via a wireless network.

[0063] In this embodiment, the acquisition module collects network status parameters of the communication device connected to the communication network in real time. The analysis module synchronously receives the network status parameters collected by the acquisition module and analyzes the instantaneous stability of the communication network based on the network status parameters. The evaluation module acquires the instantaneous stability of the communication network analyzed by the analysis module in real time and evaluates the stability of the communication network based on the continuously acquired instantaneous stability. The conversion module sets a communication status stability judgment threshold and receives the communication status stability of the communication device analyzed by the monitoring layer. Based on the comparison between the communication status stability judgment threshold and the communication status stability of the communication device, it determines whether the communication device's communication status is stable. The preprocessing module further receives the set... The determination module determines the result. If the result is negative, it obtains the audio data to be transmitted from the communication device, performs noise reduction on the audio data, and then the conversion module receives the audio data after noise reduction in the preprocessing module. It extracts text from the audio data, and finally the transmission module receives the text data extracted from the audio data by the conversion module in the conversion layer, converts the text data into a digital signal, and transmits the converted digital text data from the communication device corresponding to the audio data source to the receiving target communication device. The reading module receives the converted digital text data, restores the digital signal to the text data, and performs voice broadcast on the text data. The feedback module records the usage rate of the system's interaction layer in real time.

[0064] The above settings introduce new communication logic to communication devices such as walkie-talkies, enabling wireless communication devices to transmit communication information more stably even in poor communication environments. Furthermore, the configured communication logic allows for switching of communication modes, providing users with a better communication experience.

[0065] Example 2

[0066] At the implementation level, based on Example 1, this example refers to... Figure 1 A further detailed description of a maintenance system based on wireless communication equipment in Embodiment 1 is provided below:

[0067] In the preprocessing module, the windowing process 'c' used in the audio data output formula after noise reduction is the Hanning window.

[0068] The above settings impose logical constraints on the windowing process of audio data in the output formula of the noise-reduced audio data.

[0069] like Figure 1 As shown, the conversion module is integrated with the speech recognition module. The format conversion operation performed on the audio data in the interaction layer is the operation of the speech recognition module in the conversion module to extract the text from the audio data.

[0070] The audio data after format conversion is the text data extracted from the audio data in the conversion module.

[0071] The above settings further define the operating logic of the conversion module, ensuring that the conversion module can output text data based on the noise-reduced audio data and transmit it to the interaction layer, providing the interaction layer with the necessary operating data support.

[0072] like Figure 1 As shown, when the conversion module in the conversion layer finishes running, it synchronously feeds back the text extracted from the audio data to the interaction layer, and at the same time triggers the monitoring layer to run again. It further feeds back the stability of the communication status of the communication device analyzed by the monitoring layer to the conversion layer, and the setting module in the conversion layer continuously determines whether the communication status of the communication device is stable.

[0073] In the monitoring layer, when the device is triggered to run again, the conversion layer continuously determines whether the communication status of the communication device is stable. If the determination result is yes, the device is controlled to return to the audio data interaction state. Otherwise, the conversion layer continuously extracts text from the audio data and transmits it to the interaction layer, which then controls the interaction of the communication device.

[0074] The above settings provide a more advanced linkage operation logic for the system, enabling the system to continuously monitor the communication environment of the communication equipment, so as to continuously switch the communication data transmission logic of the communication equipment on a reliable basis.

[0075] like Figure 1 As shown, the interaction layer usage rate recorded in the feedback module is the ratio of the number of times the reading module runs to the number of audio interactions during the interaction operation performed by the communication device.

[0076] The above settings further represent the data obtained from system operation, enabling communication equipment users to better understand the real-time usage status of their devices, make adaptive management of the devices, and ensure that the communication equipment can operate more safely, stably, and reliably while equipped with the system service, thus providing communication services to users.

[0077] In summary, the system described above, applied to walkie-talkie-type communication devices, avoids traditional communication modes. It intelligently converts audio data into text data for transmission under poor communication conditions, minimizing the need for strong signal strength and a robust communication network. This results in more stable information transmission for communication devices using this system. Furthermore, the system calculates the stability of the communication network using specified analysis logic, providing operational logic support based on the results. This allows the communication device to intelligently and autonomously switch communication logic in real-time, ensuring stable communication. Additionally, the system performs noise reduction on the audio data transmitted, improving the quality of audio transmission and providing a better user experience. Noise reduction also provides further data support for text extraction, ensuring more accurate information transmission even under poor conditions and providing stable assurance for information transmission.

[0078] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
