[0035] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0036] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances for the embodiments of the present application described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0037] In addition, the meaning of the term "plurality" should be two or more.

[0038] In order to solve the problems in the existing PLC cascaded communication solution, where the AI operations of each intelligent safety circuit breaker are independent, resulting in a huge amount of computation, low control accuracy for AI models in different application scenarios, inflexible coordination and management, and low intelligence level. In one embodiment, as Figure 1 and Figure 2 shown, a cascaded communication system based on power line carrier communication is provided, which includes a power consumption manager module 100, a plurality of gateways 200, and a cloud server 300.

[0039] The power consumption manager module 100 is divided into multiple power consumption manager area modules 110 based on a preset area division rule. The power consumption manager area module 110 includes multiple power consumption managers 102 located in the same area; the multiple power consumption manager area modules 110 are communicatively connected to each other through a first PLC (Power line communication) communication network, and the multiple power consumption managers 102 in the same area are communicatively connected to each other through a second PLC communication network; multiple gateways 200 are respectively communicatively connected to the multiple power consumption manager area modules 110 through a third PLC communication network in a one-to-one correspondence; the cloud server 300 is communicatively connected to the multiple gateways 200 through a fourth PLC communication network.

[0040] Among them, the power consumption manager module 100 may include multiple power consumption manager area modules 110, which are obtained by dividing based on a preset area division rule. The power consumption manager area module 110 includes multiple power consumption managers 102, and the multiple power consumption managers 102 included in the power consumption manager area module 110 are power consumption managers 102 in the same area. One gateway 200 is configured for one power consumption manager area module 110, that is, the number of gateways 200 can be used as the basis for dividing areas. For example, one area includes one gateway 200 and several power consumption managers 102 connected to the gateway 200.

[0041] The multiple gateways 200 are respectively communicatively connected to the multiple power consumption manager area modules 110 through a third PLC communication network in a one-to-one correspondence. Furthermore, the power consumption manager area module 110 in the same area can upload the corresponding electrical information to the gateway 200 in the same area through the third PLC communication network. The gateway 200 in the same area can also send the control instructions transmitted by the cloud server 300 to the power consumption manager 102 in the same area. That is, in the same area, any power consumption manager 102 can be communicatively connected to the gateway 200 in the corresponding area through the third PLC communication network. Furthermore, within the same area, any power consumption manager 102 can upload the relevant electrical information to the gateway 200 in the corresponding area. In addition, the power consumption manager 102 can also receive the electrical information or control instructions sent by the corresponding gateway 200.

[0042] Multiple power consumption manager area modules 110 communicate with each other through the first PLC communication network. Thus, one power consumption manager area module 110 can receive the electrical information of another power consumption manager area module 110 through the first PLC communication network. That is, the power consumption managers 102 in different areas can communicate with each other through the first PLC communication network. Thus, the power consumption manager 102 in one area can receive the electrical information of the power consumption manager 102 in another area through the first PLC communication network. Multiple power consumption managers 102 in the same area communicate with each other through the second PLC communication network. Thus, any one of the power consumption managers 102 in the same area can receive the electrical information of another power consumption manager 102 in the same area.

[0043] Exemplarily, the electrical information can be obtained according to the power consumption manager 102 collecting the power consumption of its own load; the electrical information can also be obtained according to the power consumption manager 102 receiving the electrical information of another power consumption manager 102 in the same area through the second PLC communication network; the electrical information can also be obtained according to the power consumption manager 102 receiving the electrical information of the power consumption manager 102 in a non - same area through the first PLC communication network. For example, the electrical information can include but is not limited to electrical operation information, harmonic characteristic information (i.e., electrical fingerprint information), and monitoring video information (i.e., monitoring screen data).

[0044] Based on the cloud server 300 communicating with multiple gateways 200 through the fourth PLC communication network, any one of the gateways uploads the corresponding received electrical information to the cloud server 300. Thus, the cloud server 300 can store the electrical information or send the electrical information to the terminal device by means of wireless communication or wired communication. The cloud server 300 can also receive the control instructions sent by the terminal device, and send the control instructions to the gateway 200, and then send them to the corresponding power consumption manager 102 through the gateway 200.

[0045] Exemplarily, any one of the power consumption managers 102 can transmit the electrical information transmitted by the power line to the cloud server 300 (such as the big data monitoring cloud platform in the cloud) through wireless communication (such as WIFI communication, Bluetooth communication, Internet communication); here, the electrical information can include electrical operation information, harmonic characteristic information (i.e., electrical fingerprint information), and monitoring video information (i.e., monitoring screen data). The power consumption manager 102 can also receive the control instructions transmitted by the cloud server 300 and control the power consumption manager 102 according to the relevant control instructions.

[0046] Exemplarily, the power consumption manager 102 can also access the cloud server 300 (the big data monitoring cloud platform in the cloud) and terminal devices (such as mobile phones) through a 4G communication module, an NB (Narrow Band Internet of Things) communication module, or a PLC communication module. The operation data, data analysis, report generation, and remote operation of the manager can be viewed in real time on the Web side of the cloud server 300 and the terminal device side, and remote parameter setting and power-off can be performed to achieve the remote monitoring function.

[0047] In the above embodiment, the power consumption manager module 100 is divided into multiple power consumption manager area modules 110 based on a preset area division rule. The power consumption manager area module 110 includes multiple power consumption managers 102 located in the same area; multiple power consumption manager area modules 110 are communicatively connected to each other through a first PLC communication network, and multiple power consumption managers 102 in the same area are communicatively connected to each other through a second PLC communication network; multiple gateways 200 and multiple power consumption manager area modules 110 are communicatively connected to each other through a third PLC communication network in a one-to-one correspondence; the cloud server 300 and multiple gateways 200 are communicatively connected through a fourth PLC communication network. Furthermore, the power consumption manager 102 obtains electrical information and transmits the electrical information to the corresponding gateway 200 through the third PLC communication network; the gateway 200 transmits the electrical information to the cloud server 300 through the fourth PLC communication network, so that the cloud server 300 stores the electrical information in the cloud server 300 or transmits it to the terminal device; wherein, the electrical information is obtained by the power consumption manager 102 collecting its own load power consumption, the power consumption manager 102 receiving the electrical information of another power consumption manager 102 in the same area through the second PLC communication network, or the power consumption manager 102 receiving the electrical information of a power consumption manager 102 in a non-same area through the first PLC communication network; the cloud server 300 transmits the control instruction to the corresponding gateway 200 through the fourth PLC communication network according to the received control instruction from the terminal device; the gateway 200 transmits the control instruction to the corresponding power consumption manager 102 through the third PLC communication network, so that the corresponding power consumption manager 102 executes the control instruction, thereby realizing multi-area cascaded communication based on power line carrier communication. In this application, by dividing the power consumption manager 102 into areas and using the PLC communication network for information intertransmission, remote monitoring and control of the power consumption manager 102 can be achieved; a multi-area cascaded communication network of "node (i.e., power consumption manager 102) - gateway 200 - cloud" is formed through the PLC communication network to realize coordinated management between multiple areas. Furthermore, corresponding AI models can be allocated to different areas for different application scenarios (such as different areas), realizing the differential application of AI models and improving the control accuracy of AI models in different application scenarios.

[0048] Exemplarily, such as Figure 4As shown, the power consumption manager 102 may include a management control circuit and a PLC communication module. The management control circuit and the PLC communication module are communicatively connected. For two adjacent power consumption managers 102, a communication connection can be established between their respective PLC communication modules to form a second PLC communication network. Furthermore, the power consumption manager 102 can transmit the electrical information it collects to another user manager through the PLC communication module.

[0049] Exemplarily, the terminal device can be, but is not limited to, a mobile phone, a smart watch, a smart tablet, etc. The terminal device is communicatively connected to the cloud server 300. The cloud server 300 is further configured to, when any gateway 200 is disconnected from the cloud server 300, identify the gateway 200 that has been disconnected, generate a communication fault report based on the processing result, and transmit the communication fault report to the terminal device.

[0050] For example, the terminal device can receive electrical information through the network and display relevant information or monitoring screens based on the relevant electrical information. Among them, the electrical information can include the electrical operation information, harmonic characteristic information (i.e., electrical fingerprint information), and monitoring video information (i.e., monitoring screen data) collected by the corresponding power consumption manager 102. The terminal device can also generate a control instruction based on the electrical information and transmit the control instruction to the cloud server 300 through the network. Then, the cloud server 300 can transmit the control instruction to the corresponding gateway 200 through the fourth PLC communication network. The gateway 200 transmits the control instruction to the corresponding power consumption manager 102 through the third PLC communication network, so that the corresponding power consumption manager 102 executes the control instruction, thereby realizing multi-region cascaded communication based on power line carrier communication.

[0051] Furthermore, when any gateway 200 in a region is unable to communicate with the cloud server 300, that is, when any gateway 200 is disconnected from the cloud server 300, the cloud server 300 identifies the gateway 200 that has been disconnected, determines the fault region, generates a communication fault report, and sends the communication fault report to the terminal device to remind relevant personnel to troubleshoot and repair the communication equipment in the fault region. Through automatic reporting of regional communication faults, it is beneficial to troubleshoot the gateway 200 in the offline region to restore the communication between the gateway 200 in the offline region and the cloud server 300.

[0052] In one example, multiple gateways 200 are communicatively connected to each other through a fifth PLC communication network. Any one of the multiple gateways 200 is further configured to, when disconnected from the cloud server 300, obtain the electrical information transmitted by any one of the remaining gateways 200 among the multiple gateways 200.

[0053] Among them, the gateways 200 between different regions can be communicatively connected through the fifth PLC communication network. The gateway 200 that is disconnected from the cloud server 300 can receive relevant electrical information from any one of the remaining gateways 200, so as to avoid the inability to synchronize the control and management of this region with that of other regions due to the disconnection from the cloud server 300, realizing multi-region coordinated management, thereby ensuring the reliability of the control in the disconnected region.

[0054] In one example, multiple power consumption managers 102 in the same region are set to share the same AI model.

[0055] For example, a region can be regarded as an application scenario (i.e., the location of the application scenario). Then, the region information corresponding to a region is used as an environmental parameter, and the region information is unique. For example, the first region corresponds to one region information, the second region corresponds to another region information, the Nth region corresponds to another region information, and so on. Multiple power consumption managers 102 within the same region can share an AI model, and the AI model is distributed to multiple power consumption managers 102 within the same region through the PLC cascade communication network, thereby realizing the overall planning and distribution of the AI models for different application scenarios. It should be noted that the PLC cascade communication network refers to the combined communication network of the first PLC communication network, the second PLC communication network, the third PLC communication network, the fourth PLC communication network, and the fifth PLC communication network in the cascade communication system of the present application.

[0056] In one example, multiple regions with the same environmental parameters are identified as regions in the same application scenario; the power consumption managers 102 in multiple regions in the same application scenario are set to share the same AI model associated with the corresponding application scenario.

[0057] For example, multiple regions with the same environmental parameters can be considered to be in the same application scenario. For example, if the environmental parameters of the first region are the same as those of the second region, then the first region and the second region are in the first application scenario; if the environmental parameters of the third region are the same as those of the fourth region and are different from the environmental parameters of the first region and the second region, then the third region and the fourth region are in the second application scenario. The first region and the second region in the first application scenario share an AI model associated with the first application scenario; while the third region and the fourth region in the second application scenario share an AI model associated with the second application scenario.

[0058] Exemplarily, the environmental parameters include but are not limited to parameter information such as application time, temperature, humidity, and altitude.

[0059] Furthermore, a gateway that has disconnected from the cloud server 300 can achieve data inter - transmission with other gateways in its application scenario (e.g., transmitting relevant electrical information, environmental parameters of the application scenario, or AI models). Specifically, a gateway that has disconnected from the cloud server 300 can upload the data it has collected to the cloud server 300 through other gateways that are in normal communication connection with the cloud server 300. Or, a gateway that has disconnected from the cloud server 300 can receive the data sent by the cloud server 300 from other gateways that are in normal communication connection with the cloud server 300. Or, there are multiple gateways that have disconnected from the cloud server 300 within the same application scenario, and these multiple gateways that have disconnected from the cloud server 300 achieve data inter - transmission with each other. Any gateway that has disconnected from the cloud server 300 can input the electrical information or environmental parameters of the application scenario collected from all the gateways in this application scenario into the AI model for training, and send the trained AI model to other gateways in this application scenario. The above settings avoid the phenomenon that the control and management strategies of the power consumption manager by the gateway disconnected from the cloud server 300 cannot be synchronized with those of other gateways in the same application scenario, and realize the coordination degree of multi - area management in the same application scenario.

[0060] In one example, the power consumption manager 102 is further configured to obtain first training power consumption data; and use the first training power consumption data as training input parameters to train the correspondingly configured AI model; the first training power consumption data is the power consumption data collected by the power consumption manager 102 itself and / or the power consumption data collected by the remaining power consumption managers 102 in the same application scenario.

[0061] Exemplarily, the power consumption manager 102 can be provided with a learning and training module, and the learning and training module can be used to collect the electrical information and environmental parameters of the application scenario of the power consumption manager 102 in different application scenarios. The electrical information collected in the same application scenario is used as the input parameters of the AI model corresponding to the application scenario to obtain the trained AI model. Then, any power consumption manager 102 can be used to obtain the first training power consumption data, and use the first training power consumption data as the training input parameters to train the correspondingly configured AI model based on the learning and training module. Among them, the input parameters for AI model training can come from the power consumption data collected by the power consumption manager 102 itself or the power consumption data collected by other power consumption managers 102 in the same application scenario. The input parameters for AI model training can also come from the combination of the power consumption data collected by the power consumption manager 102 itself and the power consumption data collected by other power consumption managers 102 in the same application scenario.

[0062] The gateway 200 is also used to obtain the second training power consumption data, and use the second training power consumption data as the training input parameter to train the correspondingly set AI model; the second training power consumption data is the power consumption data collected by several power consumption managers 102 communicatively connected to the gateway 200 and / or the power consumption data transmitted by the remaining gateways 200 in the same application scenario.

[0063] Exemplarily, the gateway 200 can be provided with a learning and training module, which can be used to collect the electrical information of the power consumption manager 102 in different application scenarios and the environmental parameters of the application scenario. The electrical information collected in the same application scenario is used as the input parameter of the AI model corresponding to the application scenario to obtain the trained AI model. Furthermore, any gateway 200 can be used to obtain the second training power consumption data, and use the second training power consumption data as the training input parameter to train the correspondingly set AI model based on the learning and training module. Among them, the input parameter for AI model training can come from the power consumption data collected by several power consumption managers 102 connected to the gateway 200 or the power consumption data transmitted by other gateways 200 in the same application scenario to the gateway 200. The input parameter for AI model training can also come from the combination of the power consumption data collected by several power consumption managers 102 connected to the gateway 200 and the power consumption data transmitted by other gateways 200 in the same application scenario to the gateway 200.

[0064] The cloud server 300 is also used to obtain the third training power consumption data, and use the third training power consumption data as the training input parameter to train the correspondingly set AI model; the third training power consumption data is the power consumption data collected by several power consumption managers 102 in the same application scenario.

[0065] Exemplarily, the cloud server 300 can be provided with a learning and training module, which can be used to collect the electrical information of the power consumption manager 102 in different application scenarios and the environmental parameters of the application scenario. The electrical information collected in the same application scenario is used as the input parameter of the AI model corresponding to the application scenario to obtain the trained AI model. Furthermore, any cloud server 300 can be used to obtain the third training power consumption data, and use the third training power consumption data as the training input parameter to train the correspondingly set AI model based on the learning and training module. Among them, the input parameter for AI model training can come from the power consumption data collected by several power consumption managers 102 in the same application scenario, where the power consumption data is uploaded to the cloud server 300 by each power consumption manager 102 through the gateway 200 connected to it.

[0066] Further, the AI model associated with the environmental parameters can be stored in any one of the power consumption manager 102, the gateway 200, and the cloud server 300; preferably, in order to make the database more manageable, the associated AI model can be stored in the cloud server 300.

[0067] In one example, when any power consumption manager 102 requests to call the AI model, according to the environmental parameters corresponding to any power consumption manager 102, an AI model associated with the corresponding environmental parameters stored in any power consumption manager 102, any remaining power consumption manager 102, or any gateway 200 among the cloud server 300 and the remaining power consumption managers 102 is obtained, and the AI model associated with the corresponding environmental parameters is configured.

[0068] Among them, when any power consumption manager 102 needs to call the AI model, according to the environmental parameters corresponding to any power consumption manager 102, the AI model associated with the corresponding environmental parameters can be obtained from any power consumption manager 102, any gateway 200, or the cloud server 300 that stores the AI model associated with the environmental parameters, and the AI model associated with the corresponding environmental parameters is allocated to the power consumption manager 102 that needs to call the AI model through the PLC cascade communication network set in this application.

[0069] In the above embodiments, by dividing the power consumption manager 102 into regions and using the PLC communication network to transmit information mutually, remote monitoring and control of the power consumption manager 102 are realized; through the PLC communication network, a multi-region cascade communication network of "node (i.e., power consumption manager 102) - gateway 200 - cloud" is formed to realize coordinated management between multiple regions, and then corresponding AI models can be allocated to different regions for different application scenarios (such as different regions), realizing the differential application of the AI model and improving the control accuracy of the AI model in different application scenarios.

[0070] In one example, a PLC cascade communication network system for a single region, such as Figure 3 shown, multiple power consumption managers 102 are respectively communicatively connected to the gateway 200 through the third PLC communication network, and the gateway 200 is communicatively connected to the cloud server 300 through the fourth PLC communication network. As Figure 4 shown, multiple power consumption managers 102 in the same region are communicatively connected to each other through the second PLC communication network.

[0071] Any power consumption manager 102 can upload relevant electrical information to the gateway 200 through the third PLC communication network; any power consumption manager 102 can also receive the electrical information sent by other gateways 200 through the third PLC communication network; any power consumption manager 102 can also receive the electrical information sent by other power consumption managers 102 in the same area through the second PLC communication network. The gateway 200 can upload the electrical information to the cloud server 300 through the fourth PLC communication network; the gateway 200 can also send the electrical information to the power consumption manager 102 through the third PLC communication network.

[0072] The cloud server 300 can store the electrical information; the cloud server 300 can also send the electrical information to the terminal device by means of wireless communication or wired communication. The cloud server 300 can also receive the control instructions sent by the terminal device, and send the control instructions to the gateway 200 through the fourth PLC communication network, and then the gateway 200 sends them to the power consumption manager 102 through the third PLC communication network.

[0073] In one embodiment, as Figure 5 shown, a cascaded communication method based on power line carrier communication is also provided. Taking this cascaded communication method applied to the cascaded communication system as Figure 1 shown as an example, the cascaded communication method based on power line carrier communication includes the following steps:

[0074] Step S510, the power consumption manager obtains electrical information and transmits the electrical information to the corresponding gateway through the third PLC communication network; the gateway transmits the electrical information to the cloud server through the fourth PLC communication network, so that the cloud server stores the electrical information or transmits the electrical information to the terminal device; wherein, the electrical information is obtained by the power consumption manager collecting its own load power consumption, the power consumption manager receiving the electrical information of another power consumption manager in the same area through the second PLC communication network, or the power consumption manager receiving the electrical information of a power consumption manager in a different area through the first PLC communication network.

[0075] Step S520, the cloud server transmits the control instructions to the corresponding gateway through the fourth PLC communication network according to the obtained control instructions transmitted by the terminal device; the gateway transmits the control instructions to the corresponding power consumption manager through the third PLC communication network, so that the corresponding power consumption manager executes the control instructions.

[0076] Among them, the power consumption manager area modules in the same area can upload the corresponding electrical information to the gateway in the same area through the third PLC communication network. The gateway in the same area can also send the control instructions transmitted by the cloud server 300 to the power consumption managers in the same area. That is, in the same area, any power consumption manager can upload the relevant electrical information to the corresponding area gateway. In addition, the power consumption manager can also receive the electrical information or control instructions sent by the corresponding gateway. Any power consumption manager area module can receive the electrical information of another power consumption manager area module through the first PLC communication network. That is, the power consumption manager in one area can receive the electrical information of the power consumption manager in another area through the first PLC communication network. Any power consumption manager in the same area can receive the electrical information of another power consumption manager in the same area.

[0077] Exemplarily, the electrical information can be obtained according to the power consumption manager collecting the power consumption of its own load terminal; the electrical information can also be obtained according to the power consumption manager receiving the electrical information of another power consumption manager in the same area through the second PLC communication network; the electrical information can also be obtained according to the power consumption manager receiving the electrical information of the power consumption manager in a non-same area through the first PLC communication network. For example, the electrical information can include but is not limited to electrical operation information, harmonic characteristic information (i.e., electrical fingerprint information), and monitoring video information (i.e., monitoring screen data).

[0078] Any gateway can upload the corresponding received electrical information to the cloud server. Furthermore, the cloud server can store the electrical information or send the electrical information to the terminal device by means of wireless communication or wired communication. The cloud server can also receive the control instructions sent by the terminal device, send the control instructions to the gateway, and then send them to the corresponding power consumption manager through the gateway.

[0079] In the above embodiments, the electrical manager obtains electrical information and transmits the electrical information to the corresponding gateway through the third PLC communication network; the gateway transmits the electrical information to the cloud server through the fourth PLC communication network so that the cloud server stores the electrical information or transmits the cloud server to the terminal device; wherein, the electrical information is obtained by the electrical manager collecting the power consumption of its own load, the electrical manager receiving the electrical information of another electrical manager in the same area through the second PLC communication network, or the electrical manager receiving the electrical information of the electrical manager in a different area through the first PLC communication network; the cloud server transmits the control instruction to the corresponding gateway through the fourth PLC communication network according to the obtained control instruction transmitted by the terminal device; the gateway transmits the control instruction to the corresponding electrical manager through the third PLC communication network so that the corresponding electrical manager executes the control instruction, thereby realizing multi-area cascaded communication based on power line carrier communication. In this application, the electrical managers are divided into regions, and the PLC communication network is used for information intertransmission to realize remote monitoring and control of the electrical managers; a multi-area cascaded communication network of "node (i.e., electrical manager) - gateway - cloud" is formed through the PLC communication network to realize coordinated management between multiple regions, and then corresponding AI models can be assigned to different regions for different application scenarios (such as different regions), realizing the differential application of the AI models and improving the control accuracy of the AI models in different application scenarios.

[0080] In one example, as Figure 6 shown, the fault reporting steps include:

[0081] Step S610, when the cloud server disconnects the communication connection with any gateway, it performs identification processing on the gateway with the disconnected communication connection and generates a communication fault report according to the processing result.

[0082] Step S620, the cloud server transmits the communication fault report to the terminal device.

[0083] Specifically, when the gateway in any area cannot communicate with the cloud server, that is, when any gateway disconnects the communication connection with the cloud server, the cloud server identifies the gateway with the disconnected communication connection, then determines the fault area, generates a communication fault report, and sends the communication fault report to the terminal device to remind relevant personnel to troubleshoot and repair the communication equipment in the fault area. Through automatic reporting of regional communication faults, it is beneficial to troubleshoot the gateways in the offline areas to restore the communication between the gateways in the offline areas and the cloud server.

[0084] In one example, the cascaded communication method based on power line carrier communication further includes the step; when any gateway disconnects the communication connection with the cloud server, it obtains electrical information from any one of the remaining gateways.

[0085] Specifically, when any gateway disconnects from the cloud server, the gateway that has disconnected from the cloud server can receive relevant electrical information from any one of the remaining gateways, so as to avoid the inability to synchronize the control and management of this area with that of other areas due to disconnection from the cloud server, achieving multi-area coordinated management, and thus ensuring the reliability of the control in the disconnected area.

[0086] In one example, the cascaded communication method based on power line carrier communication further includes steps: when any power consumption manager requests to call the AI model, according to the environmental parameters corresponding to any power consumption manager, obtain the AI model associated with the environmental parameters stored in any power consumption manager, any gateway or the cloud server among the remaining power consumption managers, and configure the AI model associated with the environmental parameters.

[0087] Among them, when any power consumption manager needs to call the AI model, it can obtain the AI model associated with the environmental parameters from any power consumption manager, any gateway or the cloud server that stores the AI model associated with the environmental parameters according to the environmental parameters corresponding to any power consumption manager, and allocate the AI model associated with the environmental parameters to the power consumption manager that needs to call the AI model through the PLC cascaded communication network set in this application.

[0088] In the above embodiments, by dividing the power consumption managers into regions and using the PLC communication network for information intertransmission, remote monitoring and control of the power consumption managers are realized; through the PLC communication network, a multi-region cascaded communication network of "node (i.e., power consumption manager) - gateway - cloud" is formed to achieve coordinated management among multiple regions, and then corresponding AI models can be allocated to different regions for different application scenarios (such as different regions), realizing the differential application of the AI models and improving the control accuracy of the AI models in different application scenarios.

[0089] It should be understood that although Figure 5-6 the steps in the flowchart are shown in sequence according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise clearly stated in this article, the execution of these steps has no strict order limit, and these steps can be executed in other orders. Moreover, Figure 5-6 at least a part of the steps in
