[0002] Intelligent circuit breakers are common circuit protection devices. When the external load reaches the protection power range of the intelligent circuit breaker, the intelligent circuit breaker needs to take alarm action.

It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Additionally, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0046] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0047] The following examples, in conjunction with the accompanying drawings, provide specific illustrations of the circuit breaker-based load power monitoring system provided in this application.

[0048] Figure 1 This is a schematic diagram of a load power monitoring system based on a circuit breaker, provided as an embodiment of this application. Figure 1 As shown, the system includes: cloud platform 110, gateway unit 120, circuit breaker 130, and external load 140. Circuit breaker 130 is connected to cloud platform 110 through gateway unit 120. Circuit breaker 130 is also used to connect external load 140. Cloud platform 110 is connected to external load 140.

[0049] In this embodiment, the gateway unit 120 acts as an inter-network connector to connect the circuit breaker 130 and the cloud platform 110, enabling data transmission between the cloud platform 110 and the circuit breaker 130. The circuit breaker 130 is connected to an external load 140 and is used to determine whether to send alarm information and perform protection actions based on the current active power of the external load 140 and the preset protection range, thereby shutting down the circuit breaker 130 in time to avoid damage to the external load 140. The external load 140 can be any electrical load such as lamps or air conditioners.

[0050] The cloud platform 110 is used to collect the active power of the external load 140 in real time and obtain the environmental data of the external load 140; and predict the target power protection range of the external load 140 based on the preset active power prediction model and environmental data. Based on the target power protection range of the external load 140, the cloud platform 110 sends a power protection range update command to the circuit breaker 130 so that the circuit breaker 130 updates the initial power protection range to the target power protection range and detects whether the current active power of the external load 140 connected to the circuit breaker 130 exceeds the target power protection range.

[0051] The cloud platform 110 can be a smart power distribution cloud platform 110 system. Through the connection between the cloud platform 110 and the external load 140, the active power of the external load 140 is collected in real time, and the environmental data of the external load 140 is obtained. The environmental data of the external load 140 is processed by a preset active power prediction model to determine the target power protection range of the external load 140. The circuit breaker 130 is then controlled to update the initial power protection range to the target power protection range. This allows the circuit breaker 130 and the cloud platform 110 to determine whether the current active power of the external load 140 exceeds the target power protection range, whether an alarm message needs to be sent, and whether the circuit breaker 130 needs to be controlled to perform a protection action based on the target power protection range and the current active power of the external load 140 collected in real time.

[0052] It should be noted that when the load power monitoring system includes multiple external loads 140, the cloud platform 110 can communicate and connect with multiple external loads 140 through multiple expansion interfaces. For example, one circuit breaker 130 connects multiple external loads 140 and connects to the cloud platform 110 through a gateway unit 120. Alternatively, there are multiple circuit breakers 130, each circuit breaker 130 connects to multiple external loads 140, and connects to the expansion interfaces of the cloud platform 110 through the gateway units 120 corresponding to the multiple circuit breakers 130. This enables the cloud platform 110 to communicate with multiple external loads 140 through multiple expansion interfaces, collect the active power of multiple external loads 140, and detect whether the current active power of multiple external loads 140 exceeds the corresponding target power protection range.

[0053] In summary, the load power monitoring system based on a circuit breaker provided in this application includes: a cloud platform, a gateway unit, a circuit breaker, and an external load. The circuit breaker is communicatively connected to the cloud platform via the gateway unit and is also used to connect to the external load. The cloud platform is communicatively connected to the external load. The cloud platform is used to collect the active power of the external load in real time and obtain environmental data of the external load. Based on a preset active power prediction model and the environmental data, it predicts and obtains the target power protection range of the external load. Based on the target power protection range of the external load, it sends a power protection range update command to the circuit breaker, causing the circuit breaker to update its initial power protection range to the target power protection range. It also detects whether the current active power of the external load connected to the circuit breaker exceeds the target power protection range. In this system, the circuit breaker and cloud platform are connected to the external load respectively to collect the active power of the external load in real time. The circuit breaker can determine whether the active power of the external load exceeds the initial power protection range based on the initial protection range. The cloud platform can obtain the active power of the external load and the environmental data of the external load, and calculate the target power protection range of the external load according to the preset active power prediction model. It controls the circuit breaker to update the initial power protection range to the target power protection range and determines whether the active power of the external load exceeds the target power protection range. By calculating and obtaining the target power protection range of the external load, the cloud platform can more accurately determine whether the current active power of the external load exceeds the target power protection range, and promptly avoid damage to the external load.

[0054] Continue to refer to Figure 1 The system also includes a monitoring device 150, which is communicatively connected to the cloud platform 110, the circuit breaker 130, and the external load 140. The cloud platform 110 monitors the active power of the external load 140 through the monitoring device 150, and the circuit breaker 130 monitors the active power of the external load 140 through the monitoring device 150.

[0055] The monitoring equipment 150 can be a computer terminal, a large-screen terminal, a station control screen terminal, a virtual terminal, a tablet terminal, a mobile terminal, etc. The cloud platform 110 can monitor and collect the active power and alarm information of the external load 140, as well as the execution status and working condition of the circuit breaker 130, in real time through the monitoring equipment. In addition, the circuit breaker 130 can monitor and collect the active power of the external load 140 in real time through the monitoring equipment.

[0056] Figure 2 This is a schematic diagram of the structure of a circuit breaker provided in an embodiment of this application. Figure 2 As shown, the circuit breaker 130 includes a control unit, a detection unit, and an alarm module 138; wherein the control unit is connected to the detection unit and the alarm module 138 respectively.

[0057] Specifically, the control unit includes a control chip 131 and a switch control module 132; the detection unit includes a power detection module 133, a leakage current detection module 134, a voltage detection module 135, a current detection module 136, and a temperature sensing module 137. The circuit breaker 130 also includes a clock module 139, which is connected to the control chip 131.

[0058] The control chip 131 is connected to the switch control module 132, power detection module 133, leakage current detection module 134, voltage detection module 135, current detection module 136, temperature sensing module 137, and alarm module 138. The power detection module 133 in the circuit breaker 130 detects the active power of the external load 140 connected to the circuit breaker 130 and transmits the collected active power to the control chip 131. The control chip 131 determines whether the current active power exceeds the preset protection range based on the collected active power and the preset protection range. If the current active power exceeds the preset protection range, the control chip 131 sends an alarm signal to the alarm module 138, causing the alarm module 138 to sound an alarm. Furthermore, the control chip 131 sends a shutdown command to the switch control module 132, controlling the circuit breaker 130 to shut down, thus protecting the external load 140.

[0059] In addition, the leakage current detection module 134, voltage detection module 135, current detection module 136, and temperature sensing module 137 in the circuit breaker 130 are used to detect whether the leakage current data, voltage data, current data, and temperature data in the circuit breaker 130 circuit are abnormal. Based on the detected data and the corresponding preset threshold, the fault type of the circuit breaker 130 is determined, and finally, it is determined whether to shut down the circuit breaker 130.

[0060] Since the rated power of the circuit breaker is constant, the preset protection range for the external load is a fixed range, and the preset protection range is much larger than the active power of the external load. Therefore, there may be situations where the active power of the external load meets the alarm requirements, but since the active power of the external load does not exceed the preset protection range of the circuit breaker, the circuit breaker does not alarm or perform any protection action to shut down the circuit breaker, thereby causing damage to the external load.

[0061] Therefore, in order to accurately determine whether the active power of the external load needs to be alarmed, this application provides a load power monitoring method based on a circuit breaker. By adding a cloud platform, the active power of the external load is collected, environmental data of the external load is obtained, and the target power protection range of the external load is predicted according to a preset active power prediction model and environmental data. The circuit breaker is controlled to update the initial power protection range to the target power protection range, and the current active power of the external load is detected to see if it exceeds the target power protection range and whether an alarm is needed. At this time, the target power protection range of the external load is calculated based on the active power of the external load, which is smaller than the initial power protection range of the circuit breaker and closer to the actual protection range of the external load. This allows for accurate determination of whether the current active power of the external load needs to be alarmed.

[0062] The following, with reference to the accompanying drawings, provides specific examples illustrating the circuit breaker-based load power monitoring method provided in this application. This application provides a possible implementation of the circuit breaker-based load power monitoring method, applied to a cloud platform within a load power monitoring system. Figure 3 A flowchart illustrating a load power monitoring method based on a circuit breaker, as provided in this application embodiment, is shown below. Figure 3 As shown, the method includes:

[0063] S101. Collect the active power of the external load and obtain the environmental data of the external load.

[0064] In this embodiment, the cloud platform is used to collect the active power of external loads within a preset time period and obtain the environmental data of the external loads. The environmental data includes: season, weather type, temperature, and humidity. Different environmental data lead to different usage of external loads, thereby affecting the active power of the external loads. For example, when the external load is an air conditioner, the usage frequency of the external load is higher in summer, when the weather is sunny, and the temperature is above 30 degrees Celsius than in spring, when the weather is sunny, and the temperature is below 25 degrees Celsius. Therefore, the maximum active power of the external load in summer is higher than the maximum active power in spring.

[0065] S102. Based on environmental data, a preset active power prediction model is used to predict the active power of the external load and determine the target power protection range of the external load.

[0066] The preset active power prediction model is used to predict the active power of the external load in the future based on the environmental data and load type of the external load within a preset time period, and then determine the target power protection range of the external load based on the predicted active power.

[0067] S103. Based on the target power protection range of the external load, send a power protection range update command to the circuit breaker so that the circuit breaker updates the initial power protection range to the target power protection range and detects whether the current active power of the external load exceeds the target power protection range.

[0068] The cloud platform sends a power protection range update command to the circuit breaker, controlling the circuit breaker to update the initial power protection range to the target power protection range. The cloud platform obtains the current active power of the external load in real time, and determines whether the current active power of the external load exceeds the target power protection range based on the target power protection range corresponding to the external load. That is, it determines whether the current active power of the external load is greater than the maximum active power in the target power protection range. At the same time, the circuit breaker can also determine whether the current active power of the external load is greater than the target power protection range.

[0069] This application provides a load power monitoring method based on a circuit breaker, applied to a cloud platform of a load power monitoring system. The method includes: collecting the active power of an external load and obtaining environmental data of the external load, including season, weather type, temperature, and humidity. Based on the environmental data, a preset active power prediction model is used to predict the active power of the external load, determining the target power protection range for the external load. Finally, based on the target power protection range of the external load, a power protection range update command is sent to the circuit breaker, causing the circuit breaker to update its initial power protection range to the target power protection range, and detecting whether the current active power of the external load exceeds the target power protection range. This method calculates the target power protection range of the external load through a cloud platform, making the power protection range of the external load closer to its actual protection range, and accurately determining whether the current active power of the external load exceeds the target power protection range.

[0070] This application also provides another possible implementation of the load power monitoring method based on circuit breakers. Figure 4 A flowchart illustrating another load power monitoring method based on a circuit breaker provided in this application embodiment is shown below. Figure 4 As shown, before predicting the active power of the external load based on environmental data using a preset active power prediction model and determining the target power protection range of the external load, the method further includes:

[0071] S201. Obtain the active power dataset of the external load.

[0072] In this embodiment, the active power dataset includes: multiple sets of time-series data of the external load, each set of time-series data including: environmental data and the active power of the external load, the environmental data including: season, weather type, temperature, and humidity.

[0073] S202. Perform data preprocessing on the active power dataset to obtain the preprocessed active power dataset.

[0074] Specifically, for each set of time-series data in the active power dataset, the season is selected as spring, summer, autumn, and winter, and the weather type is selected as sunny or cloudy, and one-hot encoding is performed for preprocessing. The temperature and humidity in each set of time-series data in the active power dataset are normalized to obtain the preprocessed active power dataset.

[0075] S203. Based on the preprocessed active power dataset, train the preset power prediction model to obtain the target active power prediction model for the external load.

[0076] Optionally, the preprocessed active power dataset is subjected to feature processing using a first preset model to obtain a target active power dataset; the target active power dataset is trained using a preset power prediction model to obtain a target active power prediction model for external loads.

[0077] Specifically, the first preset model can use a convolutional neural network (CNN) with an attention mechanism to perform feature processing on the preprocessed active power dataset, extract spatial features, and obtain the target active power dataset.

[0078] The preset power prediction model can be trained using a Long Short-Term Memory (LSTM) network on the target active power dataset. An AM attention mechanism is then introduced to optimize the weights of the preset power prediction model, ultimately yielding a target active power prediction model for the external load. This model predicts the active power of the input external load based on environmental data, outputting the active power of the external load. The target power protection range for the external load is then determined based on the output active power.

[0079] This application embodiment also provides another possible implementation of the load power monitoring method based on a circuit breaker. According to the target power protection range of the external load, a power protection range update command is sent to the circuit breaker so that the circuit breaker updates the initial power protection range to the target power protection range. After detecting whether the current active power of the external load exceeds the target power protection range, the method further includes:

[0080] If the current active power of the external load exceeds the target power protection range, an alarm message will be sent.

[0081] Optionally, if the current active power of the external load exceeds the target power protection range, the circuit breaker is disconnected from the external load.

[0082] Specifically, if the cloud platform determines that the current active power of the external load exceeds the target power protection range, it will send an alarm message to the monitoring equipment to remind the user that the current active power of the external load exceeds the target power protection range and needs to be dealt with in a timely manner.

[0083] In addition, if the circuit breaker determines that the current active power of the external load exceeds the target power protection range, it will disconnect the connection with the external load to avoid damage to the external load in a timely manner.

[0084] This application also provides another possible implementation of a circuit breaker-based load power monitoring method, which further includes:

[0085] If the current active power of the external load obtained by the circuit breaker does not exceed the initial power protection range of the circuit breaker, but the current active power of the external load exceeds the target power protection range, an alarm message is sent and the circuit breaker is controlled to disconnect from the external load.

[0086] Specifically, both the circuit breaker and the cloud platform acquire the current active power of the external load in real time. In one example, if the current active power of the external load acquired by the circuit breaker exceeds the initial power protection range of the circuit breaker, the circuit breaker sends an alarm message to the monitoring device and sends a disconnect command to the switch control module to control the circuit breaker to disconnect.

[0087] In another example, if the current active power of the external load obtained by the circuit breaker does not exceed the initial power protection range of the circuit breaker, but the cloud platform detects that the current active power of the external load exceeds the target power protection range of the external load, the cloud platform sends an alarm message to the monitoring device.

[0088] Optionally, if the circuit breaker determines that the current active power of the external load exceeds the target power protection range, it will disconnect the connection with the external load to avoid damage to the external load in a timely manner.

[0089] When there are multiple external loads in a circuit breaker-based load power monitoring system, the cloud platform communicates with each external load through multiple expansion interfaces. This application embodiment also provides another possible implementation of a circuit breaker-based load power monitoring method, which collects the active power of the external loads, including:

[0090] The active power of each external load is collected through each expansion interface.

[0091] Specifically, the cloud platform collects the active power of each external load corresponding to each expansion interface through each expansion interface, so as to further obtain the effective power value of each external load.

[0092] The following continues to explain the circuit breaker-based load power monitoring device provided in any of the above embodiments of this application. Its specific implementation process and the resulting technical effects are the same as those in the corresponding method embodiments. For the sake of brevity, parts not mentioned in this embodiment can be referred to the corresponding content in the method embodiments.

[0093] This application provides a load power monitoring device based on a circuit breaker, which includes:

[0094] The data acquisition module is used to collect the active power of the external load and obtain environmental data of the external load.

[0095] The determination module is used to predict the active power of the external load based on environmental data and a preset active power prediction model, and to determine the target power protection range of the external load.

[0096] The sending module is used to send a power protection range update command to the circuit breaker according to the target power protection range of the external load, so that the circuit breaker updates the initial power protection range to the target power protection range and detects whether the current active power of the external load exceeds the target power protection range.
