For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units that are not listed, or can optionally include other steps or units inherent to the process, method, product or device. In addition, the terms "first", "second" and "third" and the like are used to distinguish different objects, and are not used to describe a specific order.

[0075] An embodiment of the present application provides a student dormitory management system 100, as shown in FIG. 1. Figure 1As shown, the student dormitory management system 100 includes a wireless audio device 101 installed in each dormitory, a central receiving device 102 responsible for forwarding information for the wireless audio device 101 of each dormitory building (i.e., each dormitory building is provided with a forwarding device), a cloud device 103 in wireless communication connection with the central receiving device 102, and a user device 104 running a student dormitory management application. The user device 104 includes but is not limited to a first terminal device, a second terminal device, a third terminal device, and a fourth terminal device. The first terminal device can be a device used by a student's parent, the second terminal device can be a device used by a class teacher, the third terminal device can be a device used by a grade director, and the fourth terminal device can be a device used by a dormitory manager, etc. The wireless audio device 101 and the central receiving device 102 can communicate through Long Range Radio (LoRa) wireless transmission technology or Narrow Band Internet of Things (NB-IoT). The central receiving device 102 is connected to the cloud device 103 through a wireless network, such as NB-IoT or a standard Cat.1 (LTE UE-Category 1) under the Long Term Evolution network. The student's parents, class teachers, etc. can interact with the cloud device 103 through the student dormitory management application running on the user device 104 they use, and issue information through the cloud device 103, thereby achieving the supervision or shouting of the student dormitory.

[0076] The wireless audio device 101 is configured to, in a case where a student authorization corresponding to a target dormitory is obtained, collect sound of the target dormitory to obtain first audio information, perform noise analysis on the first audio information to obtain a noise analysis result, and obtain an encoded first digital signal based on the noise analysis result through multiple encoding, and send the first digital signal to the central receiving device 102. The target dormitory can be any student dormitory in the dormitory building. Optionally, a button can be provided on the wireless audio device 101, which can be pressed by the students in the dormitory during the noon nap or at night when the lights are turned off, indicating that the students agree to collect the audio information in the dormitory.

[0077] Optionally, in terms of obtaining the encoded first digital signal based on the noise analysis result through multiple encodings, the wireless audio device is specifically configured to: convert the noise analysis result into a third digital signal; compress encode the third digital signal; and forward error correction encode the compressed encoded digital signal to obtain the first digital signal. For example, the noise analysis result can be converted into a third digital signal through an analog-to-digital conversion module, and the Opus encoding technology can be used to compress encode the third digital signal to compress the size of the noise analysis result. The compressed encoded digital signal is forward error correction encoded (FEC), i.e., the first digital signal is obtained. Since the FEC encoding is beneficial to improve the anti-interference ability of the signal in the transmission process and reduce the possibility of packet loss, the super-long distance transmission of the noise analysis result can be realized.

[0078] The central receiving device 102 is configured to receive the first digital signal sent by the wireless audio device 101 and forward the first digital signal to the cloud device through a wireless communication protocol. For example, the wireless communication protocol can be NB-IoT or Cat. 1. Optionally, the central receiving device 102 can be a gateway, a repeater, a base station, etc. installed in each building. Optionally, the central receiving device 102 can unicast, multicast or broadcast the encoded first digital signal.

[0079] The cloud device 103 is configured to receive the first digital signal sent by the central receiving device, and obtain the noise analysis result based on the first digital signal through multiple decodings. The cloud device 103 determines whether the target dormitory has noise exceeding the standard based on the noise analysis result, and sends an alarm information to the user device 104 in the case of noise exceeding the standard. Corresponding to the encoding side, the cloud device 103 first performs forward error correction decoding on the first digital signal to obtain the compressed encoded third digital signal, then decompresses the third digital signal to obtain the third digital signal, and converts the third digital signal into the noise analysis result through an analog-to-digital conversion module. The cloud device 103 determines whether the target dormitory has noise exceeding the standard based on the noise analysis result, generates corresponding alarm information if there is noise exceeding the standard, and sends the alarm information to the user device 104 for alarm reminder. For example, the alarm information can be presented to the user in the form of vibration, pop-up window, voice, text, etc. For example, the cloud device 103 can also send different alarm information according to different roles such as students, parents, class teachers, grade directors, dormitory managers, etc. For example, the dormitory manager can be sent "X0X dormitory in X building is too noisy"; the class teacher can be sent "Your Class X0X dormitory has loud noise", etc. Optionally, the cloud device 103 can generate a noise analysis chart of each dormitory and display it on the interface of the student dormitory management application. Optionally, the background can perform permission management on roles such as students, parents, class teachers, dormitory managers, etc. based on the services provided by the cloud device 103.

[0080] The user device 104 is configured to receive the alarm information sent by the cloud device 103, and convey the alarm information to the corresponding user, and receive the warning information input by the user in response to the alarm information. For example, as shown in Figure 2 The student dormitory management application interface logged in by the dormitory manager displays a pop-up window to remind the dormitory manager. For example, as shown in Figure 3 As shown in the pop-up window of the student dormitory management application, a text / voice information input box can also be provided, in which the dormitory manager can input text information or voice information to remind (or warn) the students in the target dormitory. For example, the dormitory manager can also select the target dormitory on the student dormitory management application, and then shout at the target dormitory, or select a pre-stored prompt voice or prompt text.

[0081] The cloud device 103 is also configured to receive the warning information sent by the user through the user device 104, and obtain an encoded second digital signal based on the warning information through multiple encodings, and send the second digital signal to the central receiving device 102.

[0082] Optionally, in the aspect of obtaining the encoded second digital signal based on the warning information through multiple encodings, the cloud device is specifically configured to: convert the warning information into a fourth digital signal; compress and encode the fourth digital signal, and forward error correction encode the compressed and encoded digital signal to obtain the second digital signal. For example, the warning information can be converted into a fourth digital signal through an analog-to-digital conversion module, and the fourth digital signal can be compressed and encoded using Opus encoding technology to compress the size of the warning information. The compressed and encoded digital signal is FEC encoded to obtain the second digital signal. The central receiving device 102 is also configured to receive the second digital signal, and forward the second digital signal to the wireless audio device through a wireless communication protocol.

[0083] The wireless audio device 101 is also configured to receive the second digital signal forwarded by the central receiving device 102, and obtain warning audio information based on the second digital signal through multiple decodings, and broadcast the warning audio information. Optionally, the warning information includes second audio information or text information input by the user, that is, the warning information can be audio information or text information.

[0084] Optionally, warning audio information is obtained based on the second digital signal through multiple decoding steps, including: performing forward error correction decoding on the second digital signal to obtain a decoded digital signal; performing decompression on the decoded digital signal to obtain a fourth digital signal; converting the fourth digital signal into second audio information or text information; determining the second audio information as warning audio information, or performing a speech-to-text operation on the text information to obtain warning audio information. Corresponding to the encoding side, the wireless audio device 101 first performs forward error correction decoding on the second digital signal to obtain a compressed and encoded fourth digital signal, then performs a decompression operation to obtain the fourth digital signal, and converts the fourth digital signal into second audio information or text information through an analog-to-digital converter module. If the warning information is second audio information, the wireless audio device 101 can broadcast the second audio information as warning audio information; if the warning information is text information, the wireless audio device 101 can convert the text information into corresponding speech information, i.e., obtain warning audio information, and broadcast it.

[0085] In one possible implementation, in terms of performing noise analysis on the first audio information and obtaining the noise analysis result, the wireless audio device 101 is specifically used to: perform noise estimation on the first audio information using a minimum tracking noise estimation algorithm to obtain multiple noise estimates for multiple time windows, wherein the multiple time windows correspond one-to-one with the multiple noise estimates; obtain the sound insulation of the windows of the target dormitory; obtain multiple indoor noise estimates of the target dormitory based on the multiple noise estimates and the sound insulation; and obtain the noise analysis result based on the multiple indoor noise estimates.

[0086] For example, please see Figure 4 The acquisition time of the first audio information is divided into five time windows: t1-t2, t2-t3, t3-t4, and t4-t5. Since the minimum tracking noise estimation algorithm typically requires a tracking time interval of 0.4-1 seconds, the time interval of each of the five time windows is between 0.4 and 1 second. For each time window, the minimum tracking noise estimation algorithm can be used to obtain its corresponding noise estimate, meaning that there will be five noise estimates for each of the five time windows.

[0087] In a possible implementation, in the process of obtaining the sound insulation of the window of the target dormitory, the wireless audio device 101 is specifically configured to: obtain a first average sound pressure level in a preset range outside the target dormitory; obtain a second average sound pressure level of the target dormitory; and obtain the sound insulation of the window of the target dormitory by using a total window area of the target dormitory, a total internal surface area of the target dormitory, a preset sound absorption coefficient of the target dormitory, the first average sound pressure level, and the second average sound pressure level. The wireless audio device 101 can obtain the sound pressure p in the preset range outside the target dormitory with a radius of 1 km, calculate the corresponding sound pressure level based on the sound pressure and a reference sound pressure, obtain the first average sound pressure level P1 in the preset range by averaging the sound pressure levels of the sound pressures, and obtain the first average sound pressure level P2 in the target dormitory by using the same method. The sound insulation of the window of the target dormitory is calculated by using the following formula:

[0088]

[0089] wherein R represents the sound insulation of the window of the target dormitory, S1 represents the total window area of the target dormitory, S2 represents the total internal surface area of the target dormitory, and γ represents the average sound absorption coefficient of the target dormitory, which is set to 0.2 according to the experience value. S1 and S2 can be pre-stored in a database.

[0090] In a possible implementation, in the process of obtaining the sound insulation of the window of the target dormitory, the wireless audio device 101 is specifically configured to: obtain a first average sound pressure level in a preset range outside the target dormitory; obtain a second average sound pressure level of the target dormitory; and obtain the sound insulation of the window of the target dormitory by using a total window area of the target dormitory, a total internal surface area of the target dormitory, a preset sound absorption coefficient of the target dormitory, the first average sound pressure level, and the second average sound pressure level. The wireless audio device 101 can obtain the sound pressure p in the preset range outside the target dormitory with a radius of 1 km, calculate the corresponding sound pressure level based on the sound pressure and a reference sound pressure, obtain the first average sound pressure level P1 in the preset range by averaging the sound pressure levels of the sound pressures, and obtain the first average sound pressure level P2 in the target dormitory by using the same method. The sound insulation of the window of the target dormitory is calculated by using the following formula:

[0091] N=N ′ +R-Δn;

[0092] wherein, N represents the indoor noise estimation value corresponding to the time window t2-t3, in decibel. In the same way, the indoor noise estimation values corresponding to the time windows t1-t2, t3-t4, t4-t5 can also be obtained.

[0093] In a possible implementation, in terms of obtaining the noise analysis result according to the plurality of indoor noise estimation values, the wireless audio device 101 is specifically configured to: calculate the average value of the plurality of indoor noise estimation values, take the average value as the noise value of the target dormitory, or take the median of the plurality of indoor noise estimation values as the noise value of the target dormitory, etc. Wherein, the noise analysis result includes the noise value of the target dormitory, etc. If the noise value is greater than or equal to a preset threshold (for example: 50 decibels), it is determined that the target dormitory has noise exceeding the standard, and the noise exceeding the standard is caused by indoor factors, and if the average value is less than the preset threshold, it is determined that the target dormitory does not have noise exceeding the standard. Or, the plurality of indoor noise estimation values are curve fitted, if the curve monotonically increases in the range of the minimum time point to the maximum time point of the plurality of time windows (for example: [t1, t5]), the monotonically increasing information is taken as the noise analysis result. Or, the number of times of monotonically increasing and the number of times of monotonically decreasing of the curve in the range of the minimum time point to the maximum time point of the plurality of time windows are taken as the noise analysis result, if the number of times of monotonically increasing is greater than the number of times of monotonically decreasing, it is determined that the target dormitory has noise exceeding the standard, otherwise, it is determined that the target dormitory does not have noise exceeding the standard, etc.

[0094] For example, the student dormitory management system 100 can also be applied in important notification scenarios, for example, the class teacher needs to convey a message to the student Zhang San, and Zhang San is in the dormitory at this time. The class teacher can input the message content through the student dormitory management application on the user device 104, and the cloud device 103, the central receiving device 102 to the wireless audio device 101 in the dormitory of Zhang San, to realize the notification shouting to Zhang San.

[0095] It can be seen that the student dormitory management system 100 provided by the embodiment of the application is provided by setting the wireless audio device 101, the central receiving device 102, the cloud device 103 and the user device 104 running the student dormitory management application; the wireless audio device 101 is used for collecting audio information of the student dormitory, analyzing the audio information, obtaining a noise analysis result, and compressing and encoding the noise analysis result and forward error correction encoding; the encoded digital signal is forwarded to the cloud device 103 through the central receiving device 102, the cloud device 103 performs corresponding decoding operation, obtains the noise analysis result, and determines whether the student dormitory where the wireless audio device 101 is located exists noise exceeding standard according to the noise analysis result, if exists, sends different alarm information to different users, then the user can send warning information to the cloud device 103 through the user device 104, the cloud device 103 compresses and encodes the warning information and forward error correction encoding, and forwards the encoded warning information to the wireless audio device 101 through the central receiving device 102, the wireless audio device 101 performs corresponding decoding operation, and broadcasts the warning information. In this way, in the case of excessive noise in the dormitory, the dormitory can be accurately supervised through remote information sending or shouting, without investing a large amount of human resources to patrol the dormitory, which is conducive to improving the dormitory management efficiency. In addition, in the information transmission, compression encoding is used to reduce the data size, and forward error correction encoding is performed on the compressed and encoded digital signal, which is conducive to improving the anti-interference ability of the signal in the transmission process and reducing the possibility of packet loss, so as to realize the super long distance transmission of information.

[0096] The embodiment of the application also provides a student dormitory management method, which is applied to a student dormitory management system, the student dormitory management system comprising a wireless audio device installed in each dormitory, a central receiving device responsible for information forwarding of the wireless audio device of each dormitory building, a cloud device in wireless communication connection with the central receiving device, and a user device running a student dormitory management application; please see Figure 5 The student dormitory management method comprises steps S51-S55:
