[0053] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0054] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0055] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0056] The main solution of this application embodiment is: to obtain the current data connection communication model and device status log between the smart device and the connected router; to obtain the distribution data of abnormal offline devices in the smart device based on the device status log; to determine the abnormal device based on the distribution data of abnormal offline devices; and to adjust the current data connection communication model of the abnormal device to adjust the connection and communication between the abnormal device and the router.

[0057] Because existing Wi-Fi smart air conditioners are prone to disconnection or packet loss when connected to a new router, resulting in network instability, the solution is to conduct experimental analysis on the same router or analyze and resolve the problem after it occurs, which has a certain lag and low efficiency.

[0058] This application provides a solution that pre-establishes a preset data connection communication model for smart air conditioning devices that are normally connected to the router, analyzes abnormal smart air conditioning devices to determine abnormal behavior, and synchronizes the communication rules or behaviors of the preset data connection communication model to the abnormal smart air conditioning devices, thereby achieving the effect of self-balancing connection communication stability for all devices.

[0059] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or smart device connection and communication adjustment device capable of performing the above functions. The following description uses a smart device connection and communication adjustment device as an example, in which an access layer server is deployed, to illustrate this embodiment and the following embodiments.

[0060] Based on this, embodiments of this application provide a method for adjusting the connection and communication of a smart device, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the intelligent device connection and communication adjustment method of this application.

[0061] In this embodiment, the smart device connection communication adjustment method includes steps S10 to S40:

[0062] Step S10: Obtain the current data connection communication model and device status log between the smart device and the connected router.

[0063] It should be noted that smart devices can be smart home devices, smart wearable devices, etc., such as smart air conditioners and smart refrigerators. This embodiment will use a smart air conditioner as an example for illustration.

[0064] Multiple smart devices can connect to the same router or to different routers. Due to different router protocols, the connected smart devices may experience disconnection or packet loss. Therefore, it is possible to obtain the current data connection communication model between the smart device and the corresponding router, as well as the device status log of the smart device, in real time.

[0065] The current data connection communication model represents the behavior between smart devices and connected routers, as well as the connection communication data. The behavior can include communication behavior, data reporting behavior, etc.

[0066] Device status logs consist of data from the three-terminal log packets of smart devices, and may include signal strength, channel, router model, abnormal behavior, etc. Figure 2 As shown, Figure 2 This is a schematic diagram of the three-terminal logs of the smart device, including log version 03, signal strength -39dBm, Basic Service Set Identifier (BSSID) [B4F18CB9CE30]XXX, IPv4 address 192.168.0.46, restart reason, protocol stack status: 00, protocol stack element return: 08, connection phase error code, login phase error code, and other information.

[0067] In practice, all smart air conditioning devices connected to the access layer server will report their data connection communication model and device status logs to the data bank server, such as... Figure 3 As shown, Figure 3 This diagram illustrates the data interaction between smart devices and the access layer server. Each smart device reports its connection communication model and device status log to the access layer server, which then sends them to the data bank server.

[0068] Step S20: Obtain the distribution data of abnormal offline devices in the smart devices based on the device status log.

[0069] In practice, device status logs can be analyzed to obtain distribution data of abnormal offline devices with problems among multiple smart devices.

[0070] For example, device status logs can be analyzed directly to extract information such as device online / offline status, connection time, disconnection time, and communication frequency, thereby identifying devices that are frequently offline, have unstable connections, or exceed normal offline time, thus obtaining abnormal offline device distribution data.

[0071] In one feasible implementation, steps A01 to A03 are included before step S20:

[0072] Step A01: Obtain the device access status input rules.

[0073] It should be noted that device access status input rules can be used to evaluate the connection quality between smart devices and routers or the current environmental conditions. Device access status input rules can be three-terminal log input rules for device access status, specifically including:

[0074] A. RSSI >= -70 dBm. RSSI (Received Signal Strength Indicator) is a signal strength indicator used to measure the strength of the wireless signal received by a device. -70 dBm is a threshold, indicating that the signal strength should be at least -70 dBm. This value is typically used to define an acceptable signal strength range; values ​​below this may indicate a weak signal and unstable connection.

[0075] B. SINR>=0: SINR (Signal-to-Interference plus Noise Ratio) is the ratio of signal-to-noise ratio to interference, used to measure signal quality. SINR>=0 indicates that the signal-to-noise ratio should be non-negative. A positive SINR value usually means good signal quality, while a negative value may indicate the presence of interference or noise problems.

[0076] C. errCode: errCode is an error code used to indicate problems encountered by the device at different stages. 0 indicates no error and a normal connection. 1 indicates a connection stage error, which may occur when the device attempts to connect to the router. 2 indicates a login stage error, which may occur when the device attempts to authenticate or log in to the network. 3 indicates a communication stage error, which may occur during data transmission.

[0077] D. BSSID: BSSID (Basic Service Set Identifier) ​​is a unique identifier used to identify a specific router or access point in a network. Here, it refers to the type of router the device is connected to and may be used for further analysis of connectivity issues or optimization of connection performance.

[0078] Step A02: Compare the device status log with the device access status input rules.

[0079] It should be understood that the device status log can be compared with the device access status input rules. Specifically, the device status log can be analyzed to extract key parameters, and then the key parameters can be compared with the device access status input rules.

[0080] Step A03: When the device status log does not conform to the device access status input rules, remove the smart device corresponding to the device status log.

[0081] In practice, if key parameters in the device status log do not conform to the device access status input rules, such as errCode=1, the smart device is identified as a useless device or the environment in which the smart device is located is abnormal, and this smart device is removed. By comparing the device status logs of each smart device with the device access status input rules, smart devices that do not conform to the rules are removed, resulting in an updated list of smart devices. By monitoring these parameters, connectivity problems can be detected and resolved in a timely manner, improving device connection stability and communication efficiency.

[0082] Step S30: Determine the abnormal devices based on the abnormal offline device distribution data.

[0083] It should be understood that abnormal devices can be identified through abnormal offline device distribution data. For example, abnormal offline rates or other data between each air conditioner and the same or different routers in the abnormal offline device distribution data can be used to identify abnormal devices.

[0084] In one feasible implementation, step S30 may include steps A11 to A12:

[0085] Step A11: Obtain the abnormal offline rate of devices based on the abnormal offline device distribution data.

[0086] It should be noted that after obtaining the distribution data of abnormal offline devices, the abnormal offline rate of each device can be calculated, i.e., PPM data.

[0087] As shown in Table 1, Table 1 presents the distribution data of abnormally offline devices and the corresponding abnormal offline rates of air conditioners. It includes air conditioners 1 to 6, routers 1 to 5, and the abnormal offline rate (PPM) between each air conditioner and router.

[0088] Table 1

[0089] Air conditioner / router Router 1_PPM Router 2_PPM Router 3_PPM Router 4_PPM Router 5_PPM Air conditioner 1 946 1036 1200 1125 1301 Air conditioner 2 2786 1033 1133 3301 2986 Air conditioner 3 956 2501 1163 2780 2963 Air conditioner 4 1003 1133 3301 946 1036 Air conditioner 5 1201 1163 2780 1200 1125 Air conditioner 6 3214 1033 1133 1133 3301

[0090] Step A12: Determine abnormal devices among the smart devices based on the abnormal offline rate of the devices.

[0091] It should be understood that abnormal devices among multiple smart devices can be identified based on the abnormal offline rate. For example, the abnormal offline rates (PPM) between air conditioners 1 to 5 and router 1 are 946, 2786, 956, 1003, 1201, and 3214, respectively. The device with the highest abnormal offline rate (PPM) can be reported as abnormal, i.e., air conditioner 6. An abnormal offline rate threshold can also be set, for example, set to 2800. Devices with an abnormal offline rate higher than the threshold of 2800 are considered abnormal devices, i.e., air conditioner 6.

[0092] Step S40: Adjust the current data connection communication model of the abnormal device to adjust the connection and communication between the abnormal device and the router.

[0093] In practical implementation, abnormal behaviors in the current data connection communication model of abnormal devices can be adjusted, such as abnormal connection behavior or abnormal communication behavior, so as to adjust the current data connection communication model of abnormal devices to be consistent with the data connection communication model of normal devices. This achieves the effect of self-balancing connection communication stability of all devices and avoids the problem of delayed processing caused by the failure of unstable communication of smart devices.

[0094] This embodiment provides a method for adjusting the connection and communication of a smart device. It involves acquiring the current data connection communication model and device status log between the smart device and the connected router; obtaining distribution data of abnormal offline devices in the smart device based on the device status log; identifying abnormal devices based on the abnormal offline device distribution data; and adjusting the current data connection communication model of the abnormal devices to adjust the connection and communication between the abnormal devices and the router. This method allows for the rapid identification of abnormal devices based on the smart device's status log and timely adjustment of their current data connection communication model, thereby improving the stability of the connection between the smart device and the router.

[0095] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in the first embodiment described above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 4 Step S40 includes steps S401 to S402:

[0096] Step S401: Obtain a preset data connection communication model, which includes communication information between a normal device and a connected router.

[0097] It should be noted that the preset data connection communication model is the pre-established communication information between a normal device and the connected router, including connection behavior information and communication behavior information.

[0098] In practice, a preset data communication connection model can be established in advance. This allows for direct analysis and adjustment of the current data connection communication model of the smart device when adjusting the connection communication of the smart device in the future.

[0099] In one feasible implementation, step S401 may include steps B11 to B13:

[0100] Step B11: Obtain historical connection sample data and communication sample data between smart devices and routers.

[0101] It should be noted that the historical smart devices are a sample of collected smart devices. Since the connection and communication between smart air conditioners and routers conforms to and follows the IEEE 802.11 standard protocol, a data model of the router connection and communication for each smart air conditioner can be established and recorded.

[0102] like Figure 5 As shown, Figure 5The diagram illustrates the data model for establishing a connection. When establishing a connection between air conditioner module A and router A, air conditioner module A initiates a network probe request, and router A returns a network probe response. Air conditioner module A then initiates an authentication request, and router A returns an authentication response. Finally, air conditioner module A initiates an association request, and router A returns an association response.

[0103] like Figure 6 As shown, Figure 6 This diagram illustrates the data model for establishing communication. When communication is established between air conditioner module A and router A, the sending device waits for its own time interval to expire. If the interval expires, the sending device initiates a time reservation request, sending a request frame (RTS Frame). It then waits for a reply from the peer device. Router A returns a "Clear Send" frame (CTSFrame), and the sending device, air conditioner module A, sends data communication (Data trans). The peer device, router A, returns a data acknowledgment (DataAck). The waiting time includes the longest and shortest waiting frame intervals. By establishing a data model for router connections and communication for each smart air conditioner, connection sample data and communication sample data can be obtained.

[0104] Step B12: Obtain packet sequence number, timestamp, source address, destination address, and behavior analysis based on the connection sample data and the communication sample data.

[0105] It should be noted that packet sequence numbers, timestamps, source addresses, destination addresses, and behavioral analysis can be obtained from the data in the connection sample data and communication sample data.

[0106] Step B13: Establish a preset data connection communication model based on the packet sequence number, the timestamp, the source address, the destination address, and the behavior analysis.

[0107] In practical implementation, the packet sequence number, timestamp, source address, destination address, and behavior analysis can be used to create tables, thereby obtaining multiple tables representing the connection and communication between normal devices and routers, thus forming a preset data connection and communication model. The contents of the tables also represent the connection and communication rules between smart devices and routers under normal circumstances.

[0108] As shown in Tables 2 and 3, Tables 2 and 3 respectively represent the connection and communication data rules between different smart devices and routers.

[0109] The hb request is a heartbeat request, the addba request 60s is an add block acknowledgment with a timeout of 60 seconds, and the addba response is the receiver's response to the sender's ADDBA (Add Block Ack) request.

[0112] Table 3

[0113]

[0114] Step S402: Adjust the current data connection communication model of the abnormal device according to the preset data connection communication model, so as to adjust the connection and communication between the abnormal device and the router.

[0115] It should be noted that the current data connection communication model of abnormal devices can be adjusted by using the connection or communication rules in the preset data connection communication model, so that the establishment and communication between abnormal devices and routers are consistent with those of normal devices.

[0116] In one feasible implementation, step S402 may include steps C11 to C13:

[0117] Step C11: Compare and analyze the current data connection communication model of the abnormal device with the preset data connection communication model to determine the abnormal behavior and connection communication data.

[0118] It should be noted that the current data connection communication model of the abnormal device can be compared and analyzed with the preset data connection communication model. Specifically, the comparison involves comparing the timestamp, source address, destination address, and behavior analysis to obtain abnormal behavior and connection communication data. The connection communication data may include one or more of the timestamp, source address, and destination address.

[0119] Step C12: Query the corresponding target behavior from the preset data connection communication model through the connection communication data.

[0120] In practice, data consistent with the connection communication data can be queried from the preset data connection communication model through connection communication data, and the corresponding target behavior can be obtained. The target behavior is the behavior between the normal device and the router, including connection behavior or communication behavior, etc.

[0121] Step C13: Adjust the abnormal behavior of the abnormal device through the target behavior to adjust the connection and communication between the abnormal device and the router.

[0122] In practice, the abnormal behavior of abnormal devices can be adjusted by targeting the behavior of the abnormal devices, thereby adjusting the connection and communication between the abnormal devices and the router.

[0123] By analyzing the abnormal behavior of two different air conditioners, A and B, connected to the same route A (air conditioner A being an abnormal device and air conditioner B being a normal device) and their preset data connection communication model, the cause of the abnormal behavior can be determined to be a communication heartbeat packet error. Figure 7 As shown, Figure 7 The diagram illustrates the analysis between the abnormal and normal devices, revealing a difference in the data connection communication models between the two air conditioners. Specifically: When initiating communication, router A always sends an ADDBA request for 60 seconds. According to the 802.11 standard protocol, the parsed packet aggregation frame buffer timeout is 60 seconds. Therefore, if air conditioner A finds no data response after two seconds, it initiates a timeout reconnection. Air conditioner B, however, waits for the packet aggregation buffer to be sent based on the AP's behavior, and receives a response from the router AP after 3 seconds, allowing normal communication. Therefore, the behavior of air conditioner B can be adjusted to allow air conditioner A to wait for the packet aggregation buffer to be sent based on the AP's behavior.

[0124] In specific implementation, such as Figure 8 As shown, Figure 8 This is another analytical diagram illustrating the interaction between abnormal and normal devices. Some routers default to queuing and competing for communication resources with the access point (AP). However, some routers do not require resource contention. If the router's ERP broadcast flag is not checked and data is sent directly to wait for an ACK reply, it can easily lead to data timeout and offline. Therefore, if the abnormal behavior is to send data directly to wait for an ACK reply without checking the router's ERP broadcast flag, the abnormal behavior should be adjusted according to the normal behavior (checking the router's ERP broadcast flag and then determining whether to wait for an ACK reply based on the router's ERP broadcast flag).

[0125] As shown in Tables 4 and 5, Table 4 shows the connection and communication data of air conditioner A, and Table 5 shows the connection and communication data of air conditioner B. Air conditioner A represents the normal behavior of a normal device, while air conditioner B represents the abnormal behavior of a malfunctioning device.

[0130] In practice, some routers cannot accept multiple authentication requests from the device. If the air conditioner device initiates multiple authentication requests at the underlying and application layers simultaneously, it is easy for the router to reject the access or time out the authentication response, which can easily lead to network reconnection failure. Table 6 below shows the model of connection failure caused by multiple authentication requests. Table 7 below shows the model rules for other air conditioners on the same router that the data bank discovers through the big model and reconnects normally.

[0135] This embodiment acquires a preset data connection communication model, which includes communication information between a normal device and a connected router. Based on this preset model, the current data connection communication model of the abnormal device is adjusted to regulate the connection and communication between the abnormal device and the router, ensuring that the communication performance of the abnormal device is restored and improved while maintaining a valid connection with the router. This process helps improve the stability and reliability of the entire network.

[0136] Based on the first embodiment of this application, in the third embodiment of this application, the content that is the same as or similar to that in the first embodiment described above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... ​ Step S40 includes steps S401' to S403':

[0137] Step S401': Determine the normally connected devices based on the abnormal offline device distribution data.

[0138] It should be noted that normally connected devices can be identified from the distribution data of abnormal offline devices. As shown in Table 1 above, by comparing the abnormal offline rates of devices connected to the same router, such as the abnormal offline rates of air conditioners 1 to 6 and connected to router 1, the air conditioner with the lowest abnormal offline rate is identified as the normally connected device, i.e., air conditioner 1 is the normally connected device.

[0139] Step S402': Obtain the data connection communication model of the normally connected device.

[0140] It is understandable that the data connection communication model of a normally connected device can be obtained, including the connection data, communication data, connection behavior, and communication behavior between the normally connected device and the router.

[0141] Step S403': Adjust the current data connection communication model of the abnormal device according to the data connection communication model of the normal connected device, so as to adjust the connection and communication between the abnormal device and the router.

[0142] In practice, the connection and communication behaviors in the current data connection and communication model of abnormal devices can be adjusted based on the connection and communication behaviors in the data connection and communication model of normally connected devices, thereby optimizing the abnormal offline rate of air conditioners.

[0143] As shown in Table 8, the abnormal offline rate (PPM) of the air conditioners after adjustment is shown. It can be seen that the PPM between air conditioner 2 and router 1 decreased from 2786 to 1230, and the PPM between air conditioner 6 and router 1 decreased from 3214 to 1369.

[0146] This embodiment determines normally connected devices based on the distribution data of abnormal offline devices; obtains the data connection communication model of the normally connected devices; and adjusts the current data connection communication model of the abnormal devices based on the data connection communication model of the normally connected devices, thereby adjusting the connection and communication between the abnormal devices and the router. This allows for the systematic identification and adjustment of abnormal devices, ensuring their communication behavior is consistent with that of normal devices, thereby improving the stability and reliability of the entire network.
