[0052] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0053] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0054] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0055] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0056] PLC technology is a carrier communication method that uses power lines as a medium to transmit data. It has the advantages of simple networking, no need for rewiring, and relatively low cost. It can be applied to device communication in scenarios such as whole-house intelligent control systems. Some external devices of PLC devices in PLC circuits will generate large noise during use, which will reduce the communication success rate of PLC devices in PLC circuits. Among them, external devices include lights, motors, etc.

[0057] For example, Figure 1 As shown, in the whole-house intelligent control system, the PLC device and the intelligent host are connected and communicated through power lines, and the external devices such as the dining room lights, balcony lights, and living room lights are connected to the corresponding PLC devices. The user can control the intelligent host by operating the control screen, and the PLC device controls the corresponding external devices after receiving instructions from the intelligent host. If the dining room light generates a lot of noise during use, the noise generated by the dining room light will affect the power lines near the dining room light when the dining room light is in use, thereby causing the communication through these power lines to fail. For example, the communication between the intelligent host and the PLC device corresponding to the balcony light fails, that is, the balcony light is out of control.

[0058] Therefore, it is necessary to detect the noise generated by the external devices of the PLC device in the PLC circuit during use, and process the external devices that generate relatively large noise during use based on the noise detection result, so as to improve the communication success rate of the PLC device.

[0059] In the prior art, a detection tool supporting the PLC device can be set near the PLC device. The detection tool receives the signal when the external device is turned on and the signal when the external device is turned off. The signals received by the detection tool are manually analyzed to determine the noise generated when the external device is turned on. However, this method requires manual participation, and there is a certain technical threshold for using the detection tool, with high labor costs and low detection efficiency.

[0060] In view of the above problems, the embodiments of the present application provide a noise detection method, device, equipment and storage medium, which send a detection trigger message to m target devices to be detected; the detection trigger message is used to instruct the m target devices to be detected to detect noise signals respectively within the corresponding detection time; the detection trigger message includes the detection time corresponding to the target device to be detected; m is an integer greater than 1; the detection times corresponding to different target devices to be detected are different; obtain the noise information of the m target devices to be detected; wherein, the noise information of the target device to be detected is used to characterize the noise intensity detected by the target device to be detected. In the embodiments of the present application, after sending the detection trigger message to the m target devices to be detected, the m target devices to be detected detect noise signals within the corresponding detection time, and the first device can obtain the noise information of the m target devices to be detected. In this way, obtaining the noise information of the m target devices to be detected does not require manual participation, which can improve the detection efficiency and reduce the labor cost. The following will be described in detail.

[0061] See Figure 2 , which is a schematic flowchart of a noise detection method provided by an embodiment of the present application. The method is applied to a first device, as Figure 2 shown, the method includes:

[0062] Step S201, send a detection trigger message to m target devices to be detected.

[0063] Among them, the detection trigger message is used to instruct the m target devices to be detected to detect noise signals respectively within the corresponding detection time; the detection trigger message includes the detection time corresponding to the target device to be detected; m is an integer greater than 1; the detection times corresponding to different target devices to be detected are different.

[0064] In the embodiments of the present application, when it is necessary to obtain the noise information of the m target devices to be detected, the first device sends a detection trigger message to the m target devices to be detected, and the detection trigger message can instruct the m target devices to be detected to detect noise signals within the corresponding detection time.

[0065] In order to avoid interference to the detection of noise signals by other target devices to be detected when the target device to be detected detects noise signals, different target devices to be detected detect noise signals within different detection times, that is, the detection times corresponding to different target devices to be detected are different.

[0066] In some embodiments, for each of the m target devices to be detected, the first device sends a detection trigger message including the detection time corresponding to the target device to be detected to the target device to be detected. That is, a detection trigger message including the detection time corresponding to the first target device to be detected is sent to the first target device to be detected, a detection trigger message including the detection time corresponding to the second target device to be detected is sent to the second target device to be detected, ..., a detection trigger message including the detection time corresponding to the mth target device to be detected is sent to the mth target device to be detected.

[0067] Alternatively, in some embodiments, the detection trigger message sent by the first device may include the detection times corresponding to the m target devices to be detected. The first device may send a detection trigger message including the detection times corresponding to the m target devices to be detected to each target device to be detected, or the first device may send a detection trigger message including the detection times corresponding to the m target devices to be detected to some of the target devices to be detected, and these target devices to be detected forward the detection trigger message to other target devices to be detected.

[0068] Step S202: Obtain noise information of m target devices to be detected.

[0069] The noise information of the target device to be detected is used to characterize the noise intensity detected by the target device to be detected.

[0070] In the embodiment of the present application, after sending a detection trigger message to the m target devices to be detected, the m target devices to be detected perform noise signal detection within the corresponding detection time, and the first device can obtain the noise information of the m target devices to be detected. In this way, obtaining the noise information of the m target devices to be detected does not require manual participation, which can improve detection efficiency and reduce labor costs.

[0071] In some embodiments, the first device may obtain corresponding noise information from m target devices to be detected.

[0072] As a possible implementation manner, the noise information includes noise power information.

[0073] In the embodiment of the present application, the noise power information may represent the noise intensity detected by the target device to be detected. The noise power information may be the power value of the noise signal in the signal detected by the target device to be detected.

[0074] As a possible implementation manner, the detection trigger message includes a noise detection time period.

[0075] The detection times corresponding to the m target devices to be detected are within the noise detection time period.

[0076] In an embodiment of the present application, the m target devices to be detected detect noise signals according to corresponding detection times within the noise detection time period. The noise detection time period may include a start time and an end time of the noise detection time period, and the detection times corresponding to the m target devices to be detected are after the start time of the noise detection time period and before the end time of the noise detection time period.

[0077] As a possible implementation manner, step S202 includes: receiving noise information sent by m target devices to be detected.

[0078] In an embodiment of the present application, after detecting the noise signal, the m target devices to be detected may send the noise information to the first device, and the first device may receive the noise information sent by the m target devices to be detected.

[0079] As a possible implementation manner, the detection trigger message is also used to instruct the m devices to be detected to send corresponding noise information at corresponding sending times.

[0080] The detection trigger message includes the sending time corresponding to the target device to be detected; the sending time of different target devices to be detected is different.

[0081] In an embodiment of the present application, the detection trigger message may include the corresponding sending time of the target device to be detected, indicating that m devices to be detected send corresponding noise information at the corresponding sending time.

[0082] In order to avoid the loss of noise information sent by the target device to be detected, different target devices to be detected send corresponding noise information at different times, that is, different target devices to be detected have different corresponding sending times.

[0083] As a possible implementation, refer to Figure 3 As shown, before step S201, it also includes:

[0084] Step S203: receiving a noise detection instruction.

[0085] In an embodiment of the present application, the first device may send a detection trigger message to m target devices to be detected in response to a noise detection instruction, and obtain noise information of the m target devices to be detected.

[0086] As a possible implementation, refer to Figure 3 As shown, before step S201, it also includes:

[0087] Step S204: Acquire the signal quality parameter of the device to be detected.

[0088] The signal quality parameter is a parameter used to characterize the communication quality between the device to be detected and the first device.

[0089] In the embodiment of the present application, when the first device and the device to be detected are communicating, the signal quality parameter of the device to be detected can be recorded in the first device. After receiving the noise detection instruction, the first device can obtain the signal quality parameter of the device to be detected.

[0090] In some embodiments, the first device communicates with a management node in the device to be detected, and the management node communicates with the corresponding device to be detected. The signal quality parameter of the device to be detected may be a signal-to-noise ratio of a signal of the device to be detected received by the management node. The signal quality parameter of the management node in the device to be detected may be a signal-to-noise ratio of a signal of the management node received by the first device.

[0091] Step S205: Based on the signal quality parameters of the devices to be detected, a device to be detected whose signal quality parameter is less than a signal quality threshold is determined as a target device to be detected.

[0092] In the embodiment of the present application, in order to improve the efficiency of obtaining noise information, a device to be detected that meets certain conditions can be determined as a target device to be detected. If the signal quality parameter of the device to be detected is less than the signal quality threshold, it means that the device to be detected is greatly affected by noise, and the device to be detected can be determined as a target device to be detected.

[0093] As a possible implementation manner, the device to be detected includes a device that establishes a power line carrier communication connection with the first device.

[0094] In the embodiment of the present application, the device to be detected may be a device that establishes a power line carrier communication connection with the first device. For example, the device to be detected may be a PLC device, and the first device may be a control device of the PLC device.

[0095] As a possible implementation, refer to Figure 3 As shown, the method also includes:

[0096] Step S206: Feedback the noise information of the m target devices to be detected to the user.

[0097] In the embodiment of the present application, in order to enable the user to know the noise information of the m target devices to be detected, after obtaining the noise information of the m target devices to be detected, the first device can feed back the noise information of the target devices to be detected to the user.

[0098] In some embodiments, the first device may feed back the noise information of the m target devices to be detected to the software (APP) of the user's terminal device.

[0099] Alternatively, in some embodiments, the first device may feed back the noise information of the m target devices to be detected to the user by voice broadcasting, displaying on a screen, or the like.

[0100] As a possible implementation manner, noise information of m target devices to be detected is sorted, and the sorted noise information of the m target devices to be detected is fed back to the user.

[0101] In an embodiment of the present application, in order to facilitate the user to determine the noise interference device based on the noise information of the m target devices to be detected, the noise information of the m target devices to be detected can be sorted, and the sorted noise information of the m target devices to be detected can be fed back to the user.

[0102] In some embodiments, assuming that the noise information is noise power information, the noise power information of the m target devices to be detected may be sorted in descending order of noise power.

[0103] See also Figure 3 , is a flow chart of a noise detection method provided in an embodiment of the present application, wherein the method is applied to a first device, such as Figure 3 As shown, the method includes:

[0104] Step S203: receiving a noise detection instruction.

[0105] Step S204: Acquire the signal quality parameter of the device to be detected.

[0106] Step S205: Based on the signal quality parameters of the devices to be detected, a device to be detected whose signal quality parameter is less than a signal quality threshold is determined as a target device to be detected.

[0107] Step S201: Send a detection trigger message to m target devices to be detected.

[0108] Step S202: Obtain noise information of m target devices to be detected.

[0109] Step S206: Feedback the noise information of the m target devices to be detected to the user.

[0110] See also Figure 4 , is a flow chart of a noise detection method provided in an embodiment of the present application, and the method is applied to a device to be detected. Figure 4 As shown, the method includes:

[0111] Step S401: Obtain a detection trigger message.

[0112] The detection trigger message includes the detection time.

[0113] In an embodiment of the present application, after the first device sends a detection trigger message, the device to be detected can obtain the detection trigger message, and the detection trigger message includes a detection time.

[0114] Step S402: based on the detection trigger message, the external device is turned on and the noise signal is collected within the detection time, and the external device is turned off at other times.

[0115] Among them, other time refers to time outside the detection time.

[0116] In an embodiment of the present application, the device to be detected turns on the external device and collects the noise signal within the detection time, so that the noise generated by the external device when it is turned on can be collected.

[0117] In order to prevent the external device from affecting the noise signal collected by other devices to be detected, the device to be detected turns off the external device at times other than the detection time.

[0118] As a possible implementation manner, the detection trigger message includes the noise detection time period, the detection time is within the noise detection time period, and the other time is other time within the noise detection time period except the detection time.

[0119] In an embodiment of the present application, the detection time of each device to be detected is within the noise detection time period, and the device to be detected turns off the external device at other times except the detection time within the noise detection time period, that is, the external device is turned off during the detection time of other devices to be detected, thereby avoiding the external device from affecting the noise detection of other devices to be detected.

[0120] Step S403: Determine noise information based on the noise signal.

[0121] In the embodiment of the present application, after acquiring the noise signal, the device to be detected can determine the noise information based on the noise signal.

[0122] As a possible implementation manner, the noise information includes noise power information.

[0123] In the embodiment of the present application, the noise power information may represent the noise intensity detected by the device to be detected, and the device to be detected may determine the noise power information based on the noise signal.

[0124] In some embodiments, the device to be detected may obtain a time domain signal containing noise, perform Fourier transform on the time domain signal, obtain a frequency domain signal containing noise, and determine the power information of the frequency domain signal of the target frequency band as the noise power information, wherein the target frequency band may be a frequency band used for communication. In some embodiments, the power information of the frequency domain signal of the target frequency band and the frequency band whose frequency difference with the target frequency band is less than a threshold may be determined as the noise power information.

[0125] As a possible implementation, refer to Figure 5 As shown, the method also includes:

[0126] Step S404: shut down the communication function during the noise detection period.

[0127] In an embodiment of the present application, the device to be detected turns off the communication function during the noise detection time period and stops communicating with other devices to be detected and the first device, so as to avoid interference of the communication with the collection of noise information of the device to be detected.

[0128] As a possible implementation, refer to Figure 5 As shown, the method also includes:

[0129] Step S405: After the noise detection time period ends, the communication function is enabled, and noise information is sent to the first device.

[0130] In the embodiment of the present application, after the noise detection time period ends, the device to be detected has determined the noise information and no longer collects noise signals. At this time, the communication function can be turned on and the noise information can be sent to the first device.

[0131] As a possible implementation manner, the detection trigger message includes a sending time. Sending the noise information to the first device includes: sending the noise information to the first device at the sending time.

[0132] In an embodiment of the present application, the device to be detected may send noise information to the first device at the sending time indicated in the detection trigger message.
