[0001] The present application relates to the field of smart energy technology, and in particular to a smart energy interaction system. Background Art

[0002] With the development of the Internet, mobile technology and intelligent technology, the concepts of cyber-physical systems (CPS) and cyber-physical manufacturing systems (CPPS) have emerged. The integration of industrialization and informatization is imperative. Equipment models, acquisition models and control models are the core foundation for building a control system based on the integration of industrialization and informatization. For example, IEC 61850 describes the interoperability between station-level devices and edge gateways, as well as the communication between edge gateways and central cloud. IEC 61850 achieves efficient communication and information exchange between devices through its layered architecture: station control layer, interval layer, and process layer. It uses object-oriented modeling technology and defines a data model based on a client / server structure, enabling intelligent electronic devices to exchange information through the network, significantly reducing data management costs, simplifying data maintenance, and reducing system downtime caused by configuration errors.

[0003] However, application standards at different levels are not consistent. Especially in cloud platforms, there are a large number of different types of intelligent edge products, and the standards they follow are often not unified. How to effectively connect and interact with these edge products that follow different systems is a big challenge. In related technologies, the strategy usually adopted is to downgrade interaction and use different protocols and mechanisms to process real-time data, historical data, control signals, etc.

[0004] The inventors have discovered that there are at least the following technical problems in the related art: there is a time lag in the standardization process between different terminal devices, resulting in differences in the implementation of standards by different versions of terminal devices and terminal devices in different fields. Summary of the invention

[0005] One purpose of the present application is to provide a smart energy interaction system, which is at least used to solve the technical problem that there is a time lag in the standardization process between different terminal devices in the relevant technology, resulting in differences in the implementation of standards between different versions of terminal devices and terminal devices in different fields.

[0006] To achieve the above-mentioned objectives, some embodiments of the present application provide a smart energy interaction system, which includes a cloud platform, an edge gateway and a terminal device: the cloud platform and the edge gateway are communicatively connected, and the edge gateway and the terminal device are communicatively connected; the cloud platform is configured with a model library; the model library at least includes a device model, and the device model is a virtual object determined based on the association relationship of the terminal device; the model library also includes: a logical model and an interaction model; the logical model is loaded with logical judgment conditions for determining the operations that the terminal device should perform in different situations; the interaction model is used to interact according to the device model; the edge gateway is used to receive the model of the model library from the cloud platform; and send the model of the model library to the terminal device.

[0007] Compared with the related art, in the solution provided by the embodiment of the present application, the system includes a cloud platform, an edge gateway and a terminal device: the cloud platform and the edge gateway are in communication connection, and the edge gateway and the terminal device are in communication connection; the cloud platform is configured with a model library; the model library at least includes a device model, and the device model is a virtual object determined based on the association relationship of the terminal device; the model library also includes: a logical model and an interaction model; the logical model is loaded with logical judgment conditions for determining the operations that the terminal device should perform in different situations; the interaction model is used to interact according to the device model; it can be seen that the system has a new end-edge cloud collaborative modeling method, which can provide a new interaction method; the edge gateway is used to receive the model of the model library from the cloud platform; and send the model of the model library to the terminal device; the information-physical system (CPS) system based on mode control (MC). The open model system under the MC+CPS mode is applied to realize the device integration and management in the end-edge cloud architecture. Since the model library is open, it is not only possible to customize the terminal device based on the model library, but also to intelligently learn and adapt to the characteristics of the terminal device on the edge gateway side. Since the logical model and the interaction model are set up separately, the system can directly support distributed computing based on the terminal device in terms of interaction capability, thereby achieving the purpose of improving the efficiency and flexibility of data processing. In summary, the embodiment of the present application is to establish a unified system that can process data that cannot be connected by traditional standards, making the data connection of the entire system more convenient and efficient.

[0008] In addition, in the embodiment of the present application, a logical model and an interactive model are additionally provided.

However, there is no technical solution for logical models and interactive models. The present application proposes a more comprehensive and open model library through modeling thinking. The model library not only covers traditional models, but also pioneeringly includes logical models and interactive models. The technical solution provided in the embodiment of the present application can not only adapt to existing needs, but also can be flexibly expanded to adapt to new needs that may arise in the future, thereby improving the standardization and flexibility of the system.

[0012] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0013] First embodiment

[0014] The first embodiment of the present application relates to a smart energy interaction system. Figure 1 As shown, the system may include a cloud platform, an edge gateway and a terminal device ( Figure 1 The cloud platform is connected to the edge gateway for communication, and the edge gateway is connected to the terminal device for communication; the cloud platform is configured with a model library;

[0015] The model library at least includes a device model, which is a virtual object determined based on the association relationship of the terminal device; the model library also includes: a logic model and an interaction model; the logic model is loaded with logic judgment conditions for determining the operations that the terminal device should perform in different situations; the interaction model is used to interact according to the device model;

[0016] The edge gateway is used to receive the model from the model library in the cloud platform; and send the model in the model library to the terminal device.

[0017] Exemplarily, the cloud platform can be communicatively connected to the edge gateway via an interactive bus.

[0018] Exemplarily, the models received by the edge gateway from the model library in the cloud platform refer to all models associated with a target terminal device. For example, if the target device is a transformer, all models may refer to the device model, logic model, and interaction model corresponding to the transformer.

[0019] Exemplarily, the terminal device is a physical object, which is a device in the real world. In the embodiment of the present application, by converting the terminal devices in the real world into virtual objects, these terminal devices can be operated and controlled in a virtual environment, and an interactive mode based on these virtual objects can be realized, which is conducive to improving the intelligence and automation level of the entire system.

[0020] Exemplarily, for each terminal device, a first device model, a second device model, a third device model, ... an Nth device model is generated respectively; where N is a natural number greater than or equal to 1.

[0021] Exemplarily, the model library is an open model library. An open model library means a model library that allows any device to be added and / or removed, and users can flexibly add or delete device models according to their needs. When a new device is added to the model library, the model library can start with the device model and further supplement the acquisition model and control model, logic model and interaction model as needed.

[0022] Specifically, the logic model is loaded with calculation codes for representing logic judgment conditions, and the technical codes can directly perform calculations on each remote terminal device. In other words, the logic model is used to make conditional judgments on different situations of the terminal device to determine the operations that the terminal device should perform. In some examples, the calculation code loaded by the logic model can be an if-else statement. For example, the calculation code can be referred to as follows:

[0023] proc gf3statuscalc()

[0024] {

[0025] if(gf3.nbq30.YC->value == 0){

[0026] wwxt.gf3.St2->value = 0;

[0027] wwxt.gf3.St3->value = 0;

[0028] wwxt.gf3.St4->value = 0;

[0029] wwxt.gf3.St5->value = 0;

[0030] wwxt.gf3.St6->value = 0;

[0031] wwxt.yk3=1;

[0032] }

[0033] }

[0034] In the above example, the function name of the calculation code is gf3statuscalc, and the calculation logic includes: the function first checks whether the value of the object gf3.nbq30.YC is 0. If it is, it will automatically trigger the reset operation of the terminal device corresponding to another edge gateway, such as setting the values ​​of the terminal devices wwxt.gf3.St2, wwxt.gf3.St3, wwxt.gf3.St4, wwxt.gf3.St5, and wwxt.gf3.St6 to 0, and at the same time control the terminal device named wwxt.yk3 to output a remote control signal, and the value of the remote control signal is 1.

[0035] Exemplarily, the interaction model may be used to provide a user operation interface, receive user command input, and display status.

[0036] Exemplarily, the user operation interface is used to monitor and control the terminal device. After receiving the user's command input, the current state and historical data of the terminal device can be displayed. In some examples, the interaction model can also issue an alarm to the user when an abnormality is detected.

[0037] Exemplarily, the interaction model may include basic attributes, alarm attributes, and operation attributes.

[0038] The basic attributes may include: two-dimensional primitives and three-dimensional primitives. Through the two-dimensional primitives, a two-dimensional graphical representation of the transformer, such as charts, graphs, and indicators, may be provided to display the current state and parameters of the transformer on the user operation interface. Through the three-dimensional primitives, a three-dimensional visual representation of the transformer may be provided to more intuitively display the three-dimensional structure and spatial relationship of the transformer and enhance the user's understanding of the equipment layout.

[0039] The alarm attribute may include: a color change definition and a flashing warning definition. The color change definition is used to define different color changes according to different numerical ranges of terminal device parameters to intuitively indicate the status of the parameters, such as green for normal, yellow for warning, and red for emergency. The flashing warning definition is used to indicate that under certain alarm conditions, such as when a parameter exceeds a safe range, the user is reminded by flashing an interface element to attract the user's attention and facilitate a quick response.

[0040] The operation attributes may include: digital output and analog output. The digital output may be realized by providing an output interface for control commands, allowing the user to control the digital signal of the terminal device through interface operation, such as entering or exiting the operating state of the terminal device. The analog output may be realized by providing an analog adjustment function, allowing the user to adjust the gear of the terminal device through interface operation to respond to changes in grid load or voltage fluctuations.

[0041] It can be seen that through the interactive model, the status and structure of the terminal equipment can be intuitively displayed through two-dimensional and three-dimensional graphics; the abnormal status of the terminal equipment can be quickly conveyed to the user through color change and flashing warnings to promote timely response; the output control of digital and analog quantities can be provided to allow users to perform the input, exit and gear adjustment operations of the terminal equipment; and the intuitive user interface can also be used to enhance the user experience, simplify the operation process, and improve the operation efficiency. In this way, the monitoring and control of the terminal equipment can be made more intuitive and user-friendly, while ensuring the accuracy of the operation and the timeliness of the response, which helps to improve the operation and maintenance efficiency of the terminal equipment and the overall reliability of the power grid.

[0042] Exemplarily, the interaction model may provide an interaction interface to receive a device model sent by the terminal device for characterizing the terminal device. Then the interaction module sends the received device model to the model library. The model library learns and registers the device model, so that the device model is included in the model library. Then, the model library may send the device model to the edge gateway.

[0043] Optionally, in some embodiments, the interaction model can be used for internal interaction or external interaction. Internal interaction involves calculation and control of a single device model, while external interaction involves calculation and control between multiple device models.

[0044] In some examples, the interactive model can provide users with an intuitive operating interface to display all models associated with the terminal device. Assuming that the device model is a transformer model, for example, transformers in different countries and regions generally have different styles. For example, transformers in the United States are designed according to local technical standards and user habits, while transformers in China take into account the needs and aesthetics of domestic users. The display of transformers in Europe may also have its own unique style. It can be seen that even for transformers, even if they look similar in appearance, the information and details they display may be different due to different focuses. In the embodiment of the present application, this difference can be taken into account through the interactive model, so as to be suitable for different needs and styles.

[0045] It can be seen that in some application scenarios, by using the system, the models within the interactive substation can be better managed and interacted with, and it can interact with the edge gateway based on the relevant elements within the station. At the same time, it can also interact more specifically with the cloud platform to solve the shortcomings of the existing technology in data connectivity.

[0046] Optionally, in some embodiments, the system is applied to the electrical field; the terminal device includes at least one of the following: a transformer, a relay; correspondingly, the device model includes at least one of a transformer model and a relay model.

[0047] Specifically, the application scenario is a substation as an example for explanation. Terminal devices such as transformers can be identified and classified through the object discovery process. In this way, it can be determined what object and type the terminal device is, as well as their specific role in the substation.

[0048] The model library is provided based on the substation, and the model library stores information of all equipment in the substation, including the type and characteristics of transformers. Since the model library is a database configured on the cloud platform, it is convenient to centrally manage and control all equipment in the substation.

[0049] The edge gateway acts as a bridge between the model library and the station-side devices. After the model library detects the change, the updated model is sent to the edge gateway. The edge gateway can receive models from the model library and send them to the terminal devices. The terminal devices refer to the specific devices inside the substation, such as transformers, switches, and busbars. These devices can receive models and policies from the edge gateway to achieve automated management. Through the cooperation of the model library and the edge gateway, global management of the devices in the substation can be achieved.

[0050] It is understandable that in related technologies, an end-to-end model is usually used. For example, in a substation, electrical models (such as R11) are mainly used to describe, for example, the number of windings of a transformer, the amount of current in and out, etc. However, after describing the basic properties of equipment such as transformers, the existing models have limitations in terms of how to collect data, control, and interact. In particular, when it comes to broader systems outside of substations (such as edge computing systems), existing models cannot cover all necessary interactions.

[0051] It is not difficult to find that compared with the related art, in the solution provided in the embodiment of the present application, the system includes a cloud platform, an edge gateway and a terminal device ( Figure 1 The cloud platform and the edge gateway are in communication connection, and the edge gateway and the terminal device are in communication connection; the cloud platform is configured with a model library; the model library at least includes a device model, which is a virtual object determined based on the association relationship of the terminal device; the model library also includes: a logical model and an interaction model; the logical model is loaded with logical judgment conditions for determining the operations that the terminal device should perform in different situations; the interaction model is used to interact according to the device model; it can be seen that the system has a new modeling method for end-edge-cloud collaboration, which can provide a new interaction method; the edge gateway is used to receive the model from the model library in the cloud platform; and send the model of the model library to the terminal device; the information-physical system (CPS) system based on mode control (MC). The open model system under the MC+CPS mode is applied to realize the device integration and management in the end-edge-cloud architecture. Since the model library is open, it is not only possible to customize the terminal device based on the model library, but also to intelligently learn and adapt to the characteristics of the terminal device on the edge gateway side. Since the logical model and the interaction model are set up separately, the system can directly support distributed computing based on the terminal device in terms of interaction capability, thereby achieving the purpose of improving the efficiency and flexibility of data processing. In summary, the embodiment of the present application is to establish a unified system that can process data that cannot be connected by traditional standards, making the data connection of the entire system more convenient and efficient.

[0052] In addition, in the embodiment of the present application, a logical model and an interactive model are additionally provided. Those skilled in the art should know that in the industry, common research and trial directions include device models, acquisition models, and control models. However, there is no technical solution for logical models and interactive models. The present application proposes a more comprehensive and open model library through modeling thinking. The model library not only covers traditional models, but also pioneeringly includes logical models and interactive models. The technical solution provided in the embodiment of the present application can not only adapt to existing needs, but also can be flexibly expanded to adapt to new needs that may arise in the future, thereby improving the standardization and flexibility of the system.

[0053] In addition, for other technical problems existing in related technologies: horizontally speaking, terminal devices based on the standard system have difficulty interacting. Even when following the same standard system, the interaction between different terminal devices still faces difficulties. Vertically speaking, the consistency of cloud-edge interaction is poor, and distributed computing is impossible, resulting in the inability to effectively implement distributed computing and control. Because the application standards at different levels are inconsistent, especially the cloud platform, it will face a large number and different types of smart edge-side products, and their compliance standards are often inconsistent. How to access and interact with edge-side products of various systems is a big challenge. The system provided in the embodiment of the present application can be better solved.

[0054] Second embodiment

[0055] The second embodiment of the present application relates to a smart energy interactive system. The second implementation mode is an improvement on the first embodiment, and the specific improvement is: in the second embodiment of the present application, the system further includes: an acquisition module and a generation module.

[0056] Specifically, in some embodiments, the acquisition module is used to acquire target information of the terminal device; wherein the target information includes at least one of the following: the type of the terminal device, the attributes of the terminal device, the measurement configuration of the terminal device, the association relationship between the terminal device and other devices, and the graphic element definition of the terminal device;

[0057] The generating module is used to generate the device model according to the target information.

[0058] Exemplarily, the attributes of the terminal device may include parameter attributes, topology attributes, and display attributes. In some examples, the attributes of the terminal device may specifically include at least one of the following: name information, description information, winding information, and location information of the terminal device in the power grid; the name information may be represented by Name, and the description information may be represented by Describe.

[0059] Exemplarily, the winding information may include: winding 1, winding 2, ... winding 2n. Each set of winding information may include: voltage level, associated equipment, etc.; the associated equipment may further include: busbar, knife switch, switch, etc. In some examples, the busbar refers to the busbar information connecting the transformer to the power grid; the knife switch refers to the equipment isolating the transformer from the power grid; the switch refers to the switch equipment controlling the connection between the transformer and the power grid.

[0060] It is not difficult to find that in the embodiment of the present application, the system also includes: an acquisition module and a generation module. Through the acquisition module and the generation module, the device model can be determined, and a specific implementation method of the device model is provided.

[0061] Third embodiment

[0062] The third embodiment of the present application relates to a smart energy interactive system. The third implementation mode is an improvement on the first embodiment, and the specific improvement is that: in the third embodiment of the present application, the model library also includes: an acquisition model and a control model.

[0063] Specifically, in some embodiments, the model library further includes: an acquisition model and a control model. In other words, the model library may specifically include: a device model, an acquisition model, a control model, a logic model, and an interaction model.

[0064] Wherein, the collection model is determined based on the data characteristics of the terminal device and is used to define the data collection method of the terminal device;

[0065] The control model is determined based on the control characteristics of the terminal device and is used to define the control operation of the terminal device.

[0066] Exemplarily, the acquisition model and the control model generally support corresponding measurement types. The measurement types may include not only certified measurement types, but also customized measurement types. For example, the customized measurement types may include, but are not limited to: analog quantity, state quantity, cumulative quantity, etc. In addition, it is worth mentioning that the output attributes of the control model have multiple modes, such as digital output, pulse output, customized waveform output, etc., which are not specifically limited in this embodiment.

[0067] See also Figure 2 As shown, it is an exemplary schematic diagram of the custom process and authentication process of the acquisition model and control model provided according to some application examples.

[0068] Optionally, in some embodiments, the acquisition model is specifically used to determine the data acquisition points, acquisition frequency and data type based on the terminal device, and perform data acquisition according to the data acquisition points, acquisition frequency and data type; the acquisition model may include a basic parameter acquisition unit and a cluster parameter acquisition unit.

[0069] Exemplarily, the data acquisition points may include voltage, current, temperature, etc. of each winding. The acquisition frequency is used to characterize the time interval for data acquisition according to the data acquisition points. The data types may include analog quantity and digital quantity, etc. For example, the analog quantity may correspond to voltage and current; the digital quantity may correspond to switch state.

[0070] Exemplarily, the basic parameter acquisition unit is used to acquire the main body parameters of the terminal device and the acquisition parameters of each circle for the switch device. The main body parameters may include but are not limited to the temperature, vibration signal, input and output signal and other point information of the terminal device (such as a transformer). The temperature of the transformer may be the operating temperature of the transformer; the vibration signal is used to characterize the vibration of the transformer. It can be understood that abnormal vibration may indicate that the transformer has a fault; the input and output signal is used to record the input and output operations of the transformer. The acquisition parameters of the switch device by each circle may include analog quantity, state quantity and control quantity. The analog quantity may include the number of analog signals such as voltage and current that need to be collected, the time interval for collecting the analog signal, and the determination of whether to filter the analog signal. The state signal may be, for example, a signal used to characterize the open and closed state of the switch device. The control quantity may include the type of control signal, such as a remote control command, and may also include the number of control signals that need to be sent.

[0071] Exemplarily, the cluster parameter acquisition unit is used to determine the analog quantity, state quantity and control quantity according to the cluster ID, edge gateway ID and communication address of the terminal device. For example, the analog quantity may include but is not limited to: analog quantity, simulation cycle, and whether filtering is present. The state quantity may include but is not limited to: the number of cluster IDs or the number of edge gateway IDs; the control quantity may include but is not limited to: control type and control quantity. Among them, the cluster ID is used to identify a set of terminal devices (such as transformers and their related equipment). The gateway ID may include an upper-level gateway ID and a lower-level gateway ID; the upper-level gateway ID is used to represent the gateway identifier connected to a higher-level network, and the lower-level gateway ID is used to represent the gateway identifier connected to a lower-level network. The device communication address is used to ensure that data can be correctly transmitted from the data collection point to the model library.

[0072] Optionally, in some embodiments, the system further includes a combination module; when the combination device formed by different terminal devices is detected, the combination module obtains the association relationship between the different terminal devices; and generates a combination model based on the combination device in combination with the association relationship. This allows the user to operate the combination device as a whole. Exemplarily, the combination module can generate a combination model based on the combination device according to the cluster parameter acquisition unit.

[0073] Exemplarily, the combination module is used to generate a combination model according to terminal devices of different types or different device identifiers when the association relationship between terminal devices of different types or with different device identifiers does not meet a preset threshold. It can be seen that in this embodiment, a standardized evaluation system is provided for the combination between different terminal devices, and a standardized evaluation can be performed on the association relationship between different terminal devices.

[0074] For example, when two different terminal devices (such as a transformer and a relay) are combined into a new device, a new model can be created to represent the combined device to obtain a combined model. The combined model includes the original transformer model and relay model, and forms an association relationship internally. The combined model can be managed and controlled as a whole.

[0075] Optionally, in some embodiments, the combination module is specifically used to:

[0076] Acquiring each of the terminal devices in the combined device includes at least one logical node; the logical node is used to characterize the physical attributes and functional attributes of the terminal device;

[0077] Based on the connection relationship and the logical relationship between the terminal devices, a first link and a second link are established; the first link is used to characterize the connection relationship and the logical relationship between different terminal devices; the second link is used to characterize the physical attributes and functional attributes of the different terminal devices;

[0078] Determine the association relationship based on the first link and the second link;

[0079] According to the association relationship, a combination model based on the combination device is generated.

[0080] Optionally, in some embodiments, the combination module is specifically used to:

[0081] Determine the mapping relationship between the data acquisition ports of each terminal device in the combined device;

[0082] Acquiring operation data of each terminal device in the combined device;

[0083] Determine the data logical relationship and physical relationship between the operation data based on the mapping relationship;

[0084] Based on the data logical relationship and physical relationship, a third link is established; the third link is used to characterize the data logical relationship and physical relationship between the operation data;

[0085] Determine the association relationship based on the first link, the second link and the third link;

[0086] According to the association relationship, a combination model based on the combination device is generated.

[0087] Optionally, in some embodiments, establishing a connection between the device model and the combination model, that is, in the system, associating the device model with the combination model, can enable the system to operate better.

[0088] For example, assume that the first device model, the second device model, the third device model, ... the Nth device model are all integrated on the same cloud platform. It is necessary to realize the linkage between the first device model and the second device model, taking the linkage between the air conditioner and the temperature sensor as an example, specifically, the first device model is used to control the opening and closing of the air conditioner; the second device model is used to detect the actual temperature of the temperature sensor; and the temperature detection data is generated based on the actual temperature. The cloud platform includes device models and the linkage relationship between different device models. For example, based on the temperature detection data, it can be determined whether the temperature detection data meets the first predetermined condition of the corresponding first device model; if it meets the condition, a startup parameter is sent to the first device model; when the first device model receives the startup parameter, the first device model converts the startup parameter into a startup signal and transmits the startup signal to the air conditioner; the air conditioner controls the opening of the air conditioner based on the startup signal.

[0089] It should be noted that, in some embodiments, the linkage relationship between the various device models can be determined by setting a clock; the operating data corresponds to the clock.

[0090] Specifically, if Figure 1As shown, the edge gateway is located between the cloud platform and the terminal device, and is the middleware connecting the two. The cloud platform may include multiple acquisition models, each of which corresponds to a terminal device, so as to obtain the data collected by the terminal device. Taking the terminal device as an example of a power system device, the operation data of the power system device is obtained; at the edge gateway, the clock information corresponding to the operation data is configured, and the operation data is determined based on the current clock. Based on the current clock, the edge gateway establishes an association relationship with the device model of the cloud platform. If the operation data does not match the clock, the clock information cannot be established, so that the edge gateway cannot establish an association relationship with the device model of the cloud platform.

[0091] It can be seen that by setting the clock, it is helpful to match the operating data of the terminal device with the clock, thereby realizing cloud-edge collaboration.

[0092] Exemplarily, the acquisition model is used to collect operating parameters from terminal devices, and can filter the collected analog quantities, convert the formats of state quantities and control quantities, and ensure that the data can be correctly transmitted to the model library through the edge gateway and cluster ID. The collected data can also be stored in the database for subsequent processing and analysis. Through the acquisition model, the operating status of terminal devices (such as transformers) can be monitored in real time to ensure their stable operation and provide a basis for subsequent data processing and analysis. At the same time, through cluster acquisition parameters, centralized management and monitoring of multiple terminal devices can be achieved to improve efficiency and response speed.

[0093] Optionally, in some embodiments, the control model may issue control information according to a control strategy, and adjust the control strategy according to received adjustment information.

[0094] Exemplarily, the control model may send control information to, for example, associated devices of the transformer, such as switches, etc., according to the control strategy. The adjustment information is obtained based on the execution result obtained after executing the control information.

[0095] Exemplarily, the control model may include: control lock and dynamic control. The control lock may include gear adjustment quantity control and operation lock. The gear adjustment quantity control may further include single-gear control and multi-gear control. The single-gear control is used to characterize that only one gear can be adjusted in each operation. In the multi-gear control, if n represents the number of gears that can be adjusted each time, up to n gears are allowed to be adjusted in one operation. The operation lock refers to a control operation based on a signal quantity. Specifically, whether to perform a control operation is determined by monitoring other signal quantities. For example, when the voltage is detected to be lower than a set threshold, the transformer gear is automatically adjusted to increase the output voltage. The dynamic control may include logic interlock control. That is, according to preset logical conditions, certain control operations are automatically executed or prohibited, and it is ensured that other related conditions or operations have been met or completed before an operation is performed.

[0096] It can be seen that through the control model, the gear adjustment operation of the terminal device can be accurately controlled to respond to changes in grid load or voltage fluctuations. It is also possible to protect the terminal device from improper operation by monitoring key signal quantities to ensure the safety of operation. It is also possible to dynamically adjust the control strategy based on real-time data and preset logic to optimize the performance and response time of the terminal device. In this way, the operation of the terminal device can be made more intelligent and automated while ensuring the safety and effectiveness of the operation. It helps to improve the stability of the power grid and the operating efficiency of the terminal device.

[0097] It should be noted that the control model is used to perform basic control operations, such as basic locking operations. The logic model is used to add conditional judgment logic on the basis of the control model.

[0098] In addition, it should be noted that the device model, acquisition model and control model in the embodiments of the present application can be improved in accordance with international standards or reference standards, and the embodiments of the present application do not limit the device model, acquisition model and control model.

[0099] It should be noted that the embodiment of the present application may also be an improvement based on the second embodiment.

[0100] It is not difficult to find that in the embodiment of the present application, the model library specifically includes: device model, acquisition model, control model, logic model and interaction model. By cleverly integrating the acquisition model and control model with the model library, it can be ensured that comprehensive data acquisition and control functions can be achieved at the object level based on the terminal device.

[0101] Fourth embodiment

[0102] The fourth embodiment of the present application relates to a smart energy interactive system. The fourth implementation is an improvement based on the first embodiment, and the specific improvement is: in the fourth embodiment of the present application, the interactive model includes: an active registration module.

[0103] Specifically, in some embodiments, the active registration module is used to send update information to the edge gateway when there is no device model matching the detected terminal device in the model library;

[0104] The edge gateway is used to register with the cloud platform on behalf of the detected terminal device to update the device model in the model library and obtain a device model that matches the detected terminal device.

[0105] Specifically, in some examples, if the substation has not been added to the cloud platform system before, the edge gateway can register with the upper-level cloud platform on behalf of the devices in the substation to achieve automatic interaction. In this way, transformers and other devices can be automatically added to the cloud platform system without manual intervention, which is conducive to improving efficiency.

[0106] The case where there is no device model matching the detected terminal device in the model library refers to a case where the device model changes, and the change may include adding, modifying or deleting a device model.

[0107] It is worth emphasizing that for the first update in the model library, such as changing "Device Model 1" to "Device Model 2", human intervention is generally required to execute the change. Once the device model is updated, the system can automatically recognize the change and no further human intervention is required. Specifically, the edge gateway can automatically register with the cloud platform and report the update to the model library. Then the interactive model can update the model library according to the change information. From the model library, the updated device model is automatically connected to the edge gateway and then distributed to the terminal device. In this way, this mechanism enables each model to quickly adapt to new or changed situations, ensuring that the information in the entire network is up to date and consistent.

[0108] It can be seen that in actual applications, after a new model corresponding to the terminal device is created in the model library, it can be uniformly issued from the model library; and when there are subsequent changes, the edge gateway can actively report the changes. It can be understood that the terminal device directly acts on the physical world, so the terminal device can truly perceive physical changes and automatically update these changes to the system according to physical logic. It can be seen that this two-way update mechanism can solve the technical problems when there is an unreliable connection between the model library and the terminal device, making the solution more efficient and reliable. Moreover, the entire process has a high degree of automation, which reduces human intervention and improves the response speed and accuracy of the system.

[0109] It should be noted that the embodiments of the present application may also be improvements based on the second embodiment and / or the third embodiment.

[0110] It is not difficult to find that in the embodiment of the present application, the interaction model includes: an active registration module. According to the active registration module, the edge gateway can actively register the device model, so that it can be updated in real time to ensure the consistency and real-time update of information in the entire network.

[0111] Fifth embodiment

[0112] The fifth embodiment of the present application relates to a smart energy interactive system. The fifth implementation is an improvement based on the first embodiment, and the specific improvement is that each device model is configured with a device identifier.

[0113] Specifically, in some embodiments, each device model is configured with a device identifier; the interaction model is used to access the cloud platform based on the device identifier; and / or, to perform distributed access to the edge gateway based on the device identifier.

[0114] Specifically, in some examples, the interaction model can access the cloud platform according to the device identifier of the device model to complete the access to the device model in the cloud platform. In addition, the terminal device corresponding to the device identifier on the edge gateway can be directly accessed in a distributed manner through the device identifier to achieve data acquisition and control for the terminal device.

[0115] Optionally, in some embodiments, the device identifier is determined specifically according to the type and instantiation tag of the terminal device.

[0116] It should be noted that the embodiments of the present application may also be improvements based on any one or more of the second to fourth embodiments.

[0117] It is not difficult to find that in the embodiments of the present application, each device model has a unique identifier, so that different device models can identify and control each other. For example, one device may control another device, or perform a specific operation. It can be seen that the use of unique identifiers will enable devices to interact and calculate more efficiently.

[0118] From the above embodiments, it can be seen that the system provided by the embodiments of the present application is formed based on modeling under the end-edge-cloud architecture and has a new interaction method.

Acquisition model: involves the way and method of collecting data. Control model: describes how to control and manage devices.

It aims to improve the intelligence and automation level of the system and make the management and application of model data more efficient.
