[0048] Figure 3 It is a system block diagram provided in an embodiment of the present application. DETAILED DESCRIPTION

[0049] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described through the implementation method with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0050] Reference Figure 1 , the embodiment of the present application discloses a noise detection device control method, comprising:

[0051] S1. Open the client on the mobile terminal to configure the device. It is understandable that the client in this implementation refers to the APP running on the user's mobile phone (mobile terminal). The client is adapted to the device and is used to configure the device's working mode, working parameters, permissions, etc. Including but not limited to triggering the basic functions of device detection (such as the detection capability of each working frequency band, etc.), setting the device's working mode, setting the device's networking and pairing binding, etc.

[0052] S2. The client obtains the speaker control permission. The client obtains the relevant control permission of the user's mobile phone, including the permission to control the speaker volume.

[0053] S3. By performing a preset operation on the device, the device enters the first configuration mode. The first configuration mode referred to in this embodiment includes two functions: wireless configuration of the device and detection of basic functions of the device. Generally, the configuration mode can be entered by operating certain combination buttons of the device or by operating some buttons in a specified sequence. Generally, this embodiment can be set in the initialization configuration of the first use of the device. This embodiment allows the user to configure multiple devices at the same time.

[0054] S4. Select one-touch pairing detection through the client, and instruct the user to place the device and mobile terminal. The client can guide the user to place the device and mobile phone through pictures, texts, voice, etc. It is usually recommended that the user place the mobile phone speaker towards the microphone of the device within a certain distance, such as within a distance of 20-30cm.

[0055] S5. The client obtains wireless configuration information and loads the wireless configuration information onto a pre-set first test audio to obtain a second test audio; wherein the first test audio is composed of multiple sub-audios in different frequency bands, and the sub-audios contain different amplitude changes. When the wireless configuration information is loaded onto the first test audio, the information is dispersed into sub-audios in more than two frequency bands.

[0056] The wireless configuration information referred to in this embodiment can be WIFI, Bluetooth or other Internet of Things information. In this step, the client obtains the wireless configuration information (including the wireless name and password) through a system call or user configuration, and loads the wireless configuration information to the pre-configured first test audio through a carrier. Obtain the second test audio. It is understandable that the encoding method used when loading, such as signal strength, bit identification method, verification method, etc., can be configured according to actual needs.

[0057] In this embodiment, the first test audio is a pre-set audio, which is composed of sub-audio containing multiple frequency bands. The frequency bands in which the above sub-audio is located are all frequency bands that can be detected by the noise detection device. Therefore, when the device receives audio loaded with infinite configuration information, it can detect whether each noise frequency band can be received, and at the same time detect whether the device reception is sensitive by detecting the intensity changes of each signal. It can be understood that the working range of devices with different precision is different. The main detection range of some devices is 20Hz to 12500Hz, and some detection devices are close to human hearing and can be from 20Hz to 20KHz. When selecting a frequency band for carrier, it can be selected at a certain interval. The general playback range of the mobile phone speaker can also be fully considered.

[0058] As an exemplary explanation, 10 frequency band sub-audios distributed on the detection frequency band can be selected to constitute the above-mentioned first test audio. Since different frequency bands can carry different amounts of information at the same time, you can choose to configure different amounts of information for different frequency bands according to the frequency. You can also unify the carrier information volume of each frequency band according to the frequency with the weakest carrier capacity. On one end of the device, you only need to separate the sub-audios through a filter, and then restore the carrier information according to the decoding method corresponding to the encoding method.

[0059] S6. The client controls the speaker to play the second test audio. After obtaining the second test audio based on the wireless configuration information, the client controls the speaker to play.

[0060] S7. After entering the first configuration mode, the device receives audio through a microphone, and separates the received audio according to frequency bands included in the first test audio to obtain multiple sub-audios.

[0061] It is understandable that the device can separate the sub-audio from the audio through software / hardware filters. Although there is a certain amount of sound in the environment, in a relatively quiet environment, the ambient noise can be filtered out by signal strength.

[0062] S8. Obtain bit information from each sub-audio, assemble the bit information corresponding to each sub-audio into second wireless configuration information, and determine intensity change information from each sub-audio.

[0063] In this step, the device decodes the coded bits of each sub-audio loaded onto the first test audio from each sub-audio in a preset manner, and composes the bits of each frequency band into wireless configuration information in a preset manner.

[0064] S9. Verify the function of the device using the intensity change information.

[0065] In this step, intensity changes with specific rules can be set in each sub-audio of the first test audio. By detecting the intensity changes of each sub-audio, the device can receive specific information, through which it can be tested whether the device is sensitive to sound changes. It is understandable that although there are differences in the user's device and the user's placement of the device, as long as the device does not move during the test. The device can determine the intensity changes in each stage by the intensity of certain reference information. For example, it can be agreed that the reference intensity is received at the beginning. Multiple signals of different intensities are placed in the information at the beginning. The device records these signal strengths at the beginning as a standard for judging the strength of other signals. This method can overcome the problems of differences in user mobile phones and user placement.

[0066] S10: Connect based on the second wireless configuration information. After receiving the network configuration information, the device performs wireless connection according to its program.

[0067] S11. After the device is correctly connected, the client is notified of the successful connection and the function verification. After the device completes the connection, the client can be notified of the successful connection and the result of the function verification. The device displays the configuration result through the display device on the device. For multiple devices, it is convenient for users to distinguish those that are successfully configured and those that are not.

[0068] It is understandable that this solution can initialize and configure multiple devices at the same time, which is more convenient. At the same time, the configuration of wireless settings and the detection of basic functions can be processed together, which is more efficient. In addition, this solution does not require the user's mobile phone to form a certain connection or binding relationship with the device before performing relevant configuration. For devices that have been bound to other users, they can also be configured together, and the configuration method is more flexible.

[0069] In some embodiments, each sub-audio in the first test audio includes a start information segment and a loading information segment; it can be understood that the start information segment is mainly used to identify where the information starts. The start information segment can use a different encoding from the loading information segment. For example, signals of different lengths are used to distinguish.

[0070] The obtaining bit information from each sub-audio, assembling the bit information corresponding to each sub-audio into the second wireless configuration information, and determining the intensity change information from each sub-audio specifically includes:

[0071] The device detects the start information segment and records the reference signal strength of the start information segment, wherein multiple reference signal strengths may be provided in the start information segment, for example, three fixed signals are agreed upon, and signals of three different strengths, high, medium and low, are used as references.

[0072] The device sequentially separates the bits represented by each position in the loading information segment according to the position of the starting information segment and the sliding window of a fixed size, so as to assemble the bit information corresponding to each sub-audio into the second wireless configuration information. In this step, the bits can be separated according to a certain window size according to the carrier mode, and then the bits separated from each frequency band are assembled according to a predetermined method.

[0073] Based on the signal strength at each bit position relative to the reference signal strength, the strength change information is determined. Since the communication method between the two parties is predetermined, different signal strengths can be set in at least part of the signal in each bit. For example, in a bit, whether the bit is 1 or 0 is indicated by whether the signal in the frequency band changes. The bit that changes from no to some can be represented as 0, and the bit that changes from some to no can be represented as 1. Then each bit has a signal portion, so when the signal at each bit position in the first test audio changes, the signal strength can be detected through the signal portion of the bit.

[0074] It is understandable that in this step, the device first detects the fragment of the starting information. It is understandable that the starting information can be configured in each sub-audio. It can also be configured on a certain sub-audio. The starting information is mainly used as a position reference for subsequent received information. And multiple reference information of different strengths can be set in the starting information fragment. Through these reference information, even if there are certain differences in the placement of the user's mobile phone or device, the signal strength change can be detected by comparing the strength of the reference information.

[0075] In some embodiments, determining the strength change information based on the signal strength at the position where each bit is located relative to the reference signal strength specifically includes:

[0076] Determining reference signal strengths of a plurality of preset signals in the starting information segment;

[0077] Each signal strength is mapped to a coded value according to its strength;

[0078] Based on the signal strength at the position where each bit is located, the coding value matches the reference signal strength, thereby determining a coding value sequence as the strength change information.

[0079] It is understandable that the reference signal strength can be encoded as 1, 2, 3, etc. Then some information can be decoded by the signal strength. By comparing this information with the information recorded inside the device, it can be compared whether there is a difference. If there is no difference, or the difference is acceptable, it can be considered that the device can sense the signals of each frequency band and is sensitive to the signals of different frequency bands.

[0080] Reference Figure 2In some embodiments, the method further includes a collective configuration step of configuring a plurality of the devices simultaneously:

[0081] Setting a plurality of the devices to enter a second configuration mode;

[0082] Select configuration instructions through the client;

[0083] The client loads the configuration instruction onto the first configuration audio to obtain a second configuration audio;

[0084] Instructing the user, through the client, to place the plurality of devices and mobile terminals;

[0085] Controlling the speaker through the client to play the second configuration audio;

[0086] After entering the second configuration mode, the device receives audio through a microphone and separates configuration instructions from the received audio;

[0087] Each device from which the configuration instruction is separated configures parameters according to the configuration instruction.

[0088] It is understandable that in this embodiment, the mode configuration of the device can also be performed separately without checking. The above configuration process can be a mode switch for the device, or a wireless configuration, or other configuration. It is understandable that through the above embodiment, the configuration of batch devices can be flexibly implemented. For example, in some scenarios, it is necessary to set the parameters of these devices in batches, and when the operation of the device itself is more troublesome, the above scheme can be used for batch configuration. Similarly, some devices were originally designed to be connected via Bluetooth and configured using the user's mobile phone. The above scheme can also be used in batch configuration without requiring the user to connect and bind the device first. At the same time, this configuration scheme is not controlled by the number of connections such as Bluetooth.

[0089] In some embodiments, each sub-audio in the first test audio includes multiple segments of different frequencies in the frequency band corresponding to the sub-audio. It is understandable that by setting a filter in a certain frequency range, signals that vary within a certain range can be filtered out. Therefore, for a sub-audio, setting segments of different frequencies can further test the detection capability of the device on more frequency samples.

[0090] In some embodiments, the device is a handheld noise detection device or a fixed noise detection device.

[0091] In some embodiments, the wireless configuration information is the wireless configuration information of the mobile terminal or the wireless location information of the router.

[0092] Reference Figure 3 , the embodiment of the present application provides a noise monitoring device control system, including:

[0093] Memory, used to store programs;

[0094] A processor is used to load the program to implement the control method.
