[0016] Embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings. While some embodiments of this disclosure are shown in the drawings, it should be understood that this disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this disclosure. It should be understood that the accompanying drawings and embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of protection of this disclosure.

[0017] In the description of embodiments of this disclosure, the term "comprising" and similar terms should be understood as open-ended inclusion, i.e., "including but not limited to". The term "based on" should be understood as "at least partially based on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The term "some embodiments" should be understood as "at least some embodiments". Other explicit and implicit definitions may also be included below.

[0018] In this document, unless explicitly stated otherwise, performing a step in response to A does not mean that the step is performed immediately after A, but may include one or more intermediate steps.

[0019] It is understood that the data involved in this technical solution (including but not limited to the data itself, the acquisition, use, storage or deletion of the data) shall comply with the requirements of relevant laws, regulations and related provisions.

[0020] As mentioned earlier, in the communication process of power distribution systems, wireless sensors in distribution panels are usually used in conjunction with gateways. A typical networking approach involves placing a gateway in the distribution panel and forming a network with the wireless sensors. However, in actual operation, abnormal offline status of wireless sensors is a common network fault encountered in the early stages of operation of distribution panels. Causes of abnormal offline status include sensor damage, incorrect sensor installation, and gateway malfunction. Current troubleshooting requires maintenance personnel to capture and analyze communication packets on-site to locate the problem and observe sensor indicator lights before opening the panel for repair. However, this method is insecure, inefficient, requires specialized skills and tools, and has high maintenance costs.

[0021] In view of this, this disclosure provides a scheme for anomaly detection in a power distribution system. In this scheme, the corresponding gateway information of multiple gateways in the power distribution system and the device identifier of at least one abnormal device are obtained. Each of the multiple gateways is used to establish a communication connection with a corresponding group of network devices in multiple groups of network devices in the power distribution system. The at least one abnormal device is at least one network device in the multiple groups of network devices whose communication connection status is abnormal. Based on the working channel of each gateway, it is determined whether each gateway and each network device in its corresponding group of network devices can establish a communication connection. In response to determining that the first gateway among the multiple gateways cannot establish a communication connection with the first network device, the device identifier of the first network device is determined. Subsequently, in response to the device identifier of the first network device matching the device identifier of at least one abnormal device, the gateway information of the first gateway is presented. Therefore, communication faults between gateways and network devices can be remotely investigated through the working channel, improving the efficiency of network anomaly investigation and reducing operation and maintenance costs.

[0022] The following description will focus on exemplary embodiments of the present disclosure with reference to the accompanying drawings. Figure 1 A schematic diagram of an example communication environment 100 in which embodiments of the present disclosure can be implemented is shown. It is worth noting that the present disclosure is not limited to the modules / systems involved in the communication environment 100. Any additions or replacements to the modules / systems shown in the figure to achieve similar purposes should be considered as included within the scope of the present disclosure.

[0023] like Figure 1 As shown, the communication environment 100 may be, for example, the communication environment of a power distribution system and includes a terminal device 110, a switch 120, multiple gateways 130-1 and 130-2, and multiple network devices 140-1 and 140-2. In embodiments of this disclosure, the terminal device 110 and the multiple gateways 130-1 and 130-2 can communicate via the switch 120, and the multiple network devices 140-1 and 140-2 can communicate with their respective gateways 130-1 and 130-2.

[0024] Such terminal device 110 can be any type of mobile terminal, fixed terminal, or portable terminal, including mobile phones, desktop computers, laptop computers, notebook computers, netbook computers, tablet computers, media computers, multimedia tablets, personal communication system (PCS) devices, personal navigation devices, personal digital assistants (PDAs), audio / video players, digital cameras / camcorders, positioning devices, television receivers, radio broadcast receivers, e-book devices, gaming devices, or any combination thereof, including accessories and peripherals of these devices or any combination thereof.

[0025] Terminal device 110 can provide application services to users. For example, users can use terminal device 110 to obtain the corresponding gateway information of multiple gateways 130-1 and 130-2 to determine the name and IP address of each gateway, thereby monitoring the working status of each gateway in real time.

[0026] The power distribution system may include multiple distribution panels. Multiple gateways 130-1 and 130-2 may be installed in different distribution panels and communicate with a corresponding set of network devices. Each set of network devices includes one or more network devices, each installed in a corresponding distribution panel. The network devices may be wireless sensors, such as wireless temperature sensors. The wireless temperature sensors can monitor the temperature rise of the busbar in real time within the panel, and notify the terminal device 110 via the corresponding gateway when the busbar overheats, thereby triggering an alarm for the distribution panel. It should be understood that the network devices may also be other types of measuring devices, and this disclosure does not limit their use.

[0027] In some embodiments, the communication environment 100 may be connected to a local area network. Data collection It is compatible with Supervisory Control and Data Acquisition (SCADA) systems. SCADA systems can acquire data via the Modus TCP protocol. In the event of a network device going offline or experiencing connection abnormalities, terminal device 110 can receive reporting information from the gateway to indicate the device identifier of the abnormal device.

[0028] It should be understood that Figure 1 The number of devices and their connections shown are merely illustrative and not limiting. Communication environment 100 may include any suitable number of devices configured to implement the exemplary embodiments of this disclosure. Although not shown, it should be understood that one or more other devices may be deployed in communication environment 100.

[0029] Figure 2 A flowchart of a process 200 for anomaly detection according to some embodiments of the present disclosure is shown. Process 200 can be implemented as follows: Figure 1The terminal devices shown are 110.

[0030] like Figure 2 As shown in box 210, terminal device 110 can run host computer software. The host computer software can use the gateway already deployed on site to find network devices with communication abnormalities, so as to remotely troubleshoot faults that occur during communication.

[0031] In box 220, terminal device 110 can obtain a gateway list. The gateway list includes corresponding gateway information for multiple gateways in the power distribution system. In some embodiments, terminal device 110 can use the Simple Service Discovery Protocol (SSDP) to discover all gateways within the local area network and display the gateway information of the gateways through a user interface (UI).

[0032] In box 230, terminal device 110 can obtain the device identifier of an abnormal device. An abnormal device is a network device in the power distribution system with an abnormal communication connection status. In some embodiments, terminal device 110 can receive the device identifier (ID) of the abnormal device entered by maintenance personnel in the host computer software based on the Zigbee network to initiate the search for the abnormal device.

[0033] Figure 3 An example interface 300 for locating anomalous devices according to some embodiments of the present disclosure is shown. In some embodiments, such as Figure 3 As shown, the example interface 300 includes multiple controls, such as a list retrieval control 310, a device search control 320, etc. Maintenance personnel can retrieve a list of gateways based on the Zigbee network by triggering the list retrieval control 310, thereby obtaining gateway information for multiple gateways.

[0034] In some embodiments, the example interface 300 includes an input field 330. By entering the device identifier of at least one malfunctioning device in the input field 330 and then triggering the device search control 320, a search for the malfunctioning device can be initiated. Furthermore, the example interface 300 also includes a search results list 340. The search results list 340 is used to indicate the location of the malfunctioning device. The method for indicating the location of the malfunctioning device and the method for searching for it will be described in detail below.

[0035] Continue to refer to Figure 2 In box 240, terminal device 110 can determine the operating channels of all gateways. In some embodiments, terminal device 110 can send a request to each gateway sequentially via an application programming interface (API) to obtain the Zigbee communication channel currently operating for each gateway.

[0036] In block 250, terminal device 110 can scan multiple gateways operating on different working channels. In some embodiments, terminal device 110 can perform simultaneous scanning based on a whitelist of each gateway to obtain a first scan result. The whitelist indicates the preset connection relationship between the gateway and multiple network devices; that is, only network devices included in the whitelist are allowed to establish communication connections with the gateway, while network devices not on the whitelist will be rejected by the gateway from establishing communication connections. It should be understood that the preset connection relationship between the gateway and multiple network devices can also be stored in any form to achieve the above-mentioned technical effects, and this disclosure does not limit this.

[0037] In some embodiments, the first scan result may indicate the device identifier of the network device that cannot establish a communication connection with multiple gateways operating on different working channels and the number of times the communication connection was refused. Based on the first scan result, the terminal device 110 may preliminarily determine the network device that cannot establish a communication connection with multiple gateways.

[0038] In block 260, terminal device 110 can sequentially scan multiple gateways operating on the same working channel to obtain a second scan result. In some embodiments, terminal device 110 needs to wait for the scanning cycle of the previous gateway to end before starting the scan of the next gateway.

[0039] In some embodiments, the second scan result may indicate the device identifier of the network device that cannot establish a communication connection with multiple gateways operating on the same working channel and the number of times the communication connection was refused. Based on the second scan result, the terminal device 110 may further determine the network device that cannot establish a communication connection with multiple gateways.

[0040] In some embodiments, when the gateway is performing a whitelist-based scan, it may record the device identifier of a device that is rejected from accessing the network because it is not in the whitelist and the number of times it has been rejected.

[0041] In box 270, after scanning all gateways, terminal device 110 can obtain the device identifiers and rejection counts of all devices whose communication connections were refused from all gateways. In some embodiments, terminal device 110 can send requests to all gateways via an application programming interface (API) to obtain scan results, such as the first and second scan results described above.

[0042] Further, in box 280, terminal device 110 can determine whether the device identifiers of the multiple network devices obtained in the above steps match the device identifier of at least one abnormal device. If they match, process 200 proceeds to box 291.

[0043] In box 291, terminal device 110 can sequentially present gateway information for gateways corresponding to multiple network devices. In some embodiments, such as Figure 3 As shown, the search results list 340 can display the device identifiers of multiple network devices, the IP addresses of the gateways corresponding to the multiple network devices, and the number of times each network device has been rejected by its corresponding gateway.

[0044] In some embodiments, the search results list 340 can display the gateway name and IP address in descending order of the number of rejections. Since the closer the gateway and network device are, the higher the frequency of back-and-forth interactions, meaning the more times communication connections are rejected, the more maintenance personnel can determine the communication distance between the abnormal device and the gateway by the number of rejections, and then determine the IP address of the gateway closest to the abnormal device. This facilitates troubleshooting of abnormal devices and greatly improves work efficiency.

[0045] If, at box 280, it is determined that the device identifiers of multiple network devices do not match the device identifier of at least one abnormal device, then process 200 proceeds to box 292. At box 292, terminal device 110 can display a prompt message. The prompt message indicates that the network devices obtained through scanning do not match at least one abnormal device, thus informing maintenance personnel that no abnormal device was found within the communication range. This method avoids maintenance personnel having to manually open and inspect each cabinet at the power distribution site, significantly reducing time costs and improving operational safety.

[0046] Figure 4 A flowchart of an anomaly detection process 400 according to some embodiments of the present disclosure is shown. Process 400 can be implemented at terminal device 110.

[0047] In box 410, terminal device 110 obtains the corresponding gateway information of multiple gateways in the power distribution system and the device identifier of at least one abnormal device. Each of the multiple gateways is used to establish a communication connection with a corresponding group of network devices in the multiple groups of network devices in the power distribution system. The at least one abnormal device is at least one network device in the multiple groups of network devices whose communication connection status is abnormal.

[0048] In box 420, terminal device 110 determines, based on the working channel of each gateway, whether each gateway and each network device in the corresponding group of network devices can establish a communication connection.

[0049] In box 430, in response to determining that the first gateway among a plurality of gateways cannot establish a communication connection with the first network device, the terminal device 110 determines the device identifier of the first network device.

[0050] In box 440, in response to the device identifier of the first network device matching the device identifier of at least one abnormal device, the terminal device 110 presents the gateway information of the first gateway.

[0051] In some embodiments, determining whether each gateway and each network device in a corresponding set of network devices can establish a communication connection includes: identifying at least two gateways operating on different working channels among a plurality of gateways; scanning the at least two gateways to obtain a first scan result, the first scan result indicating at least the device identifier of the network device that cannot establish a communication connection with the at least two gateways operating on different working channels and the number of times the communication connection was refused; and based on the first scan result, determining that a first gateway and a first network device cannot establish a communication connection.

[0053] In some embodiments, process 400 further includes: in response to the first gateway and the first network device being unable to establish a communication connection, determining the number of times the first network device is refused to establish a communication connection by the first gateway.

[0054] In some embodiments, process 400 further includes: in response to a device identifier of the first network device matching a device identifier of at least one abnormal device, presenting the device identifier of the first network device and the number of times the first network device has been refused a communication connection by the first gateway.

[0055] In some embodiments, the first gateway is one of a plurality of first gateways, the first network device is one of a plurality of first network devices, and presenting the gateway information of the first gateway includes: presenting the gateway information of the gateways corresponding to the plurality of network devices in sequence based on the number of times each of the plurality of network devices has been refused to establish a communication connection by its corresponding gateway.

[0056] In some embodiments, in response to a mismatch between the device identifier of the first network device and the device identifier of at least one abnormal device, a prompt message is displayed, indicating that the first network device does not match the at least one abnormal device.
