Technical Field

[0002] As a core device in power systems, circuit breakers' existing opening and closing control methods (such as manual levers or base motors) are no longer adequate for the needs of smart grids and suffer from numerous problems. These include: circuit breakers installed at high locations or in confined spaces present significant operational difficulties; opening and closing operations require manual intervention, posing a high risk of electric shock or misoperation; and the lack of closed-loop control measures means that the operation results are not readily available afterward. Currently, methods to address these issues include multiple rounds of manual confirmation, operation via PLC screens, and control via mobile terminals. However, these methods still suffer from reliance on manual intervention, the need for fixed terminals, and the lack of secondary confirmation. Therefore, there is an urgent need for a circuit breaker control system that enables non-contact control and provides feedback on operational status. Utility Model Content

[0015] Figure 1 This is a schematic diagram of the structure of the circuit breaker control system provided in an embodiment of the present disclosure; Figure 2 This is a schematic diagram of the structure of the control interaction component provided in the embodiments of this disclosure; Figure 3 This is a schematic flowchart of the circuit breaker control process provided in an embodiment of this disclosure. Detailed Implementation

[0016] This disclosure provides a circuit breaker control system. Preferred embodiments of this disclosure are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of this disclosure. Furthermore, the embodiments and features described herein can be combined with each other unless otherwise specified.

[0017] This disclosure provides a circuit breaker control system, such as... Figure 1 As shown, it includes: housing 1, circuit breaker 2, drive assembly 3, control interaction assembly 4, and control circuit 5; The circuit breaker 2 and the drive assembly 3 are disposed inside the housing 1; the input terminal and the output terminal of the circuit breaker 2 are respectively connected to the external circuit; the lever of the circuit breaker 2 is driven by the drive assembly 3, and the connection relationship between the input terminal and the output terminal is changed by changing the position of the lever, thereby controlling the opening and closing of the external circuit. The control interaction component 4 is disposed on the outer wall of the housing and is used to receive control commands and status information, and to output electrical signals to the control circuit 5; wherein, the status information is collected by the control circuit 5 and transmitted to the control interaction component 4; The control circuit 5 is disposed inside the housing 1 and is used to receive the electrical signal and generate a drive signal to drive the drive assembly 3 to change the position of the lever.

[0018] In this embodiment of the disclosure, the circuit breaker 2 is an electrical switching element that can control the opening and closing of a circuit, enabling the circuit to be connected and disconnected, and the circuit breaker 2 can automatically disconnect the overload or short-circuit current in the circuit.

[0019] The housing 1 of the circuit breaker control system is the physical carrier of the entire control system. It mainly plays a role in protection and fixation, and can isolate moisture, dust and external impact. At the same time, it can prevent personnel from accidentally touching the internal live parts. Specifically, it can be made of flame-retardant plastic.

[0020] Circuit breaker 2 is a component that directly controls the on / off state of external circuits. Its input terminal is connected to the circuit on the upstream power supply side, and its output terminal is connected to the downstream load side. It can control the on / off state of the circuit that transmits electrical energy from the power supply side to the electrical equipment. By moving the lever of circuit breaker 2, the circuit connection between the input and output terminals can be changed, thereby controlling the on / off state of electrical energy transmission.

[0021] In this disclosure, the drive component 3 can be the power source for the operation of the circuit breaker. The drive component 3 can convert control commands into mechanical kinetic energy, drive the lever to change position, and push the circuit breaker 2 to operate.

[0022] In this disclosure, operators can control the circuit breaker control system via the control interaction component 4. The control interaction component 4 can be located on the outside of the housing 1 to receive voice information issued by the operator. The voice information can be voice control commands (e.g., closing or opening) issued by the operator to the circuit breaker, enabling non-contact control of the circuit breaker.

[0023] Furthermore, the control interaction component 4 can also receive status information, which can be the status of the circuit breaker (e.g., whether the circuit breaker is closed or open) and the status of the external circuit (e.g., the current, voltage, and fault status of the external circuit). The control interaction component can also present the status of the circuit breaker and the external circuit to the operator through audio-visual information, enabling the operator to understand the execution status of the issued commands. The circuit breaker status can refer to whether the circuit breaker is open or closed; the external circuit status can include: normal operation, open circuit, short circuit, overcurrent, overvoltage, and overload status, and can also include real-time acquired data such as voltage, current, and load of the external circuit.

[0024] In practical applications, after receiving the voice information, the control interaction component 4 can determine, based on the circuit breaker's status and the external circuit's status, whether executing the voice control command in the voice information will cause negative impacts such as short circuits, overcurrents, and overloads to the external circuit. If such a possibility exists, the control interaction component 4 can intercept the command, refrain from generating a power signal to the control circuit, and simultaneously inform the operator of the situation through audio-visual information. If the external circuit still operates safely and normally after executing the voice control command, the voice control command in the voice information can be converted into an electrical signal and sent to the control circuit 5. This design adds a safety analysis function to the circuit breaker control system, preventing the circuit breaker from executing dangerous operating commands.

[0025] The control circuit 5 can be a circuit that controls the drive component 3. The control circuit 5 can convert the electrical signal output by the control interaction component 4 into a drive signal for the drive component 3, and control the drive component 3 to perform corresponding operations.

[0026] In yet another embodiment provided in this disclosure, such as Figure 2 As shown, the control interaction component 4 includes: a voice coprocessor 401, a security coprocessor 402, a main control chip 403, and an interaction module 404; The voice coprocessor 401 is connected to the interaction module 404 and is used to receive voice information through the interaction module 404 and output circuit breaker control signals to the safety coprocessor 402. The security coprocessor 402 is connected to the voice coprocessor 401 and is used to receive the circuit breaker control signal and output the execution signal to the main control chip 403. The main control chip 403 is connected to the security coprocessor 402 and the control circuit 5, and is used to receive the execution signal; send electrical signals to the control circuit 5, and send feedback signals to the interaction module 404.

[0027] In this embodiment of the disclosure, the control interaction component 4 can be a computer system with functions such as data storage, calculation, signal transmission and reception, and voice recognition.

[0028] The voice coprocessor 401 in the control interaction component 4 can be a dedicated computer subsystem equipped with a voice and semantic recognition model. This voice coprocessor 401 can be constructed from dedicated chips such as a digital signal processor (DSP), a neural processing unit (NPU), and a field-programmable gate array (FPGA). The voice coprocessor 401 can perform noise reduction and filtering operations on the received sound information through the DSP to enhance the frequencies corresponding to the speech content in the sound information. Then, based on the pre-trained speech recognition model stored in the voice coprocessor 401, the NPU converts the speech content into text information. Further, based on the pre-trained semantic recognition model stored in the voice coprocessor 401, the NPU extracts valid voice control commands from the text information, determines the actual operational intent corresponding to the voice control commands, and generates corresponding circuit breaker control signals that can be recognized by the computer system based on the operational intent.

[0029] The security coprocessor 402 can be a dedicated computer subsystem equipped with a model that predicts circuit change trends based on current data within the circuit. This security coprocessor 402 can be built using dedicated chips such as DSPs, NPUs, and FPGAs. Based on a pre-trained warning and protection model stored in the security coprocessor 402, the NPU can predict whether executing a circuit breaker control signal will trigger a safety warning in the external circuit, based on received circuit breaker control signals and status information. It then generates an execution signal based on the analysis results and sends the execution signal to the main control chip 403. The security coprocessor 402 and the voice coprocessor 401 can communicate using a Universal Asynchronous Receiver Transmitter (UART); the security coprocessor 402 and the main control chip 403 can also communicate using UART.

[0030] The main control chip 403 can be a chip with signal transmission and reception, calculation, and data storage capabilities; specifically, it can be implemented as a system-on-a-chip (SOC). The main control chip 403 can output electrical signals to the control circuit 5 according to the execution signal indication. The main control chip 403 can also transmit feedback signals to the interaction module 404. The feedback signals can be determined based on the status information transmitted from the control circuit. Through the feedback signals, the interaction module 404 can output information representing the execution status of the operator's voice message, as well as the current status of the circuit breaker and the external circuits.

[0031] In practical applications, if the safety coprocessor 402 can determine that the sound information will not trigger a safety warning in the external circuit, the main control chip 403 can also generate a corresponding feedback signal based on the execution signal and send it to the interaction module 404 so that the staff can receive feedback. Based on the feedback, the staff can issue a sound message to confirm the execution of the instruction, and reconfirm the voice control instruction in the sound message so that the circuit breaker control system can officially execute the instruction.

[0032] In this embodiment, the speech recognition model stored in the speech coprocessor 401 is trained with a large amount of speech data and possesses speech and semantic recognition capabilities. This model can analyze the input sound information and convert it into text information, providing a foundation for subsequent command recognition.

[0033] After obtaining the text information, a semantic recognition model can extract key terms from it to clarify the true purpose of the voice information and convert it into standardized voice control commands. The semantic recognition model may also include a command database specifically designed for circuit breaker control. This command database contains various possible voice control commands and their corresponding circuit breaker control signals. When the voice coprocessor 401 extracts the voice control command from the voice information, it performs a query and matching in the command database to find the corresponding circuit breaker control signal and outputs it to the safety coprocessor 402 for further safety analysis and control operations.

[0034] This instruction database can be a Natural Language to Structured Query Language (NL2SQL) database. By mapping voice instructions containing key information to corresponding standardized programming languages ​​in the database, voice information and programming languages ​​can be mapped to each other, enabling the control of circuit breaker 2 to be turned on and off via voice.

[0035] The aforementioned speech recognition model can be trained based on architectures such as Convolutional Neural Networks (CNN), Long Short-Term Memory (LSTM), or Recurrent Neural Networks (RNN). First, large-scale, multi-scene speech data can be acquired, and this data undergoes data cleaning, including removing silence segments, correcting text errors, and extracting features. The speech data is then converted into a format that the model can read; for example, the speech data can be captured as Mel-frequency cepstral coefficients.

[0036] The speech recognition model is trained by first extracting basic sound features from the bottom layer of the neural network, then combining these features in the middle layers while capturing the temporal relationships of the sounds, and finally mapping specific combinations of sound features and temporal relationships to a given text. This training process is repeated iteratively, adjusting model parameters using a loss function and optimizer, until the accuracy of the training data reaches the expected level.

[0037] It should be noted that the voice coprocessor 401 can also have voiceprint recognition functionality. It captures the frequency distribution differences in the voice emitted by staff and vectorizes these differences into machine-readable digital vectors—this digital vector is the voiceprint. Before the circuit breaker control system is used for the first time, this voiceprint can be registered and stored as a dedicated voiceprint model in the voice coprocessor 401. During the process of the voice coprocessor 401 receiving sound information, the received sound information can be vectorized into a digital vector and compared with the digital vector of the voiceprint model. If the difference between the two is less than a certain threshold, it can be considered as voice information emitted by a person with a registered voiceprint, and the circuit breaker control system can further execute the instructions issued by this person. If the difference between the digital vector of the sound information and the digital vector of the voiceprint model is greater than the set threshold, it can be considered as voice information emitted by a person who has not registered their voiceprint, and is an invalid instruction that can be ignored by the circuit breaker control system. This design can prevent the circuit breaker control system from being illegally controlled by unauthorized personnel, ensuring the safety of the circuit system.

[0038] In this embodiment of the disclosure, to avoid the speech recognition model from misrecognizing sound information, a specific wake-up keyword can be preset in the speech recognition model. This wake-up keyword can be a special phrase that is not frequently used in daily work and life. Before issuing a control command for the circuit breaker, the user must first say the preset wake-up keyword. Only when the speech coprocessor 401 detects the wake-up keyword will it further recognize the voice control commands in the subsequent sound information.

[0039] This method effectively reduces interference from environmental noise or other irrelevant voices, preventing the circuit breaker control system from performing erroneous operations due to misidentification, and improving the accuracy and safety of system operation. Furthermore, the wake-up keyword settings can be flexibly adjusted to adapt to the needs of different application scenarios.

[0040] In another embodiment provided in this disclosure, the main control chip 403 is further configured to receive status information transmitted from the control circuit and to transmit the status information to the security coprocessor 402.

[0041] In this embodiment, the main control chip 403 can also receive status information sent by the control circuit 5 and transmit the status information to the security coprocessor 402 as the basis for the security coprocessor 402 to judge the status of the external circuit.

[0042] The main control chip 403 can also determine the execution status of the voice control command issued by the staff based on the status information (e.g., whether the command was successfully executed), and convert the execution status into audio-visual information, which is then output to the staff through the interaction module 404 so that the staff can receive feedback on the audio information he issued.

[0043] Furthermore, the main control chip 403 can also store the above execution status as log text in a specific storage space. The log text may include: the textual content of the received sound information, the voice control command extracted from the sound information, the time when the voice control command was issued, the triggering status of the security warning, and the corresponding execution status.

[0044] In this embodiment, the early warning protection model stored in the security coprocessor 402 is obtained through learning from a large amount of circuit operation data and fault cases, and has the ability to predict and assess the circuit state. This model can receive real-time data from the circuit breaker control signal and the state information of the control circuit 5. This state information may include information such as the current current, voltage, and power factor of the external circuit. Through pre-stored algorithms and judgment logic in the model, it predicts the state that the external circuit may reach after the circuit breaker control signal is executed.

[0045] Subsequently, the safety coprocessor 402 compares the prediction results with pre-set warning thresholds. These warning thresholds are determined based on circuit safety operating standards, equipment capacity, and historical data, aiming to ensure that after the circuit breaker 2 performs its operation, all data from the external circuit do not exceed safe limits. Through comparative analysis, the safety coprocessor 402 can determine whether executing the circuit breaker control signal will trigger a safety warning, such as potential risks like overload, overcurrent, short circuit, overvoltage, and undervoltage. This analysis result is then sent as an execution signal to the main control chip 403, enabling the main control chip 403 to make appropriate decisions and handle the situation.

[0046] This early warning and protection model can employ machine learning or deep learning architectures to learn patterns of early warning signs of fault risks from a large amount of circuit data. First, the acquired circuit data is cleaned, missing values ​​are filled, and outliers are removed. Then, based on the temporal characteristics of the data, core data is selected through correlation analysis. This data is then divided into training, validation, and test sets. Corresponding loss functions are matched, and training is completed using the selected architecture. Finally, the early warning and protection model is obtained through testing on the test set.

[0047] In another embodiment provided in this disclosure, the status information is normal status information, and the execution signal is the circuit breaker control signal; the circuit breaker control signal is used to instruct the main control chip 403 to send a corresponding electrical signal to the control circuit; or The status information is a warning status information, and the execution signal is a circuit breaker warning signal; the circuit breaker warning signal is used to instruct the main control chip 403 not to send electrical signals to the control circuit.

[0048] In this embodiment, if the safety coprocessor 402 can determine, through the early warning protection model and the input status information combined with the circuit breaker control signal, that the external circuit can still operate normally with stable voltage after the circuit breaker executes the signal, then it can be said that the external circuit and the circuit breaker are in a normal state, and this status information is normal state information. The safety coprocessor 402 can send the circuit breaker control signal as an execution signal to the main control chip 403, and the main control chip 403 can generate a corresponding electrical signal according to the circuit breaker control signal.

[0049] If the safety coprocessor 402 can determine, based on the input status information and the circuit breaker control signal, that an abnormal situation may occur in the external circuit after the circuit breaker executes the signal, then this status information is a warning status signal. The safety coprocessor 402 can intercept the circuit breaker control signal and output a circuit breaker warning signal. Upon receiving the warning status signal, the main control chip 403 will not generate an electrical signal. The main control chip 403 can also generate a feedback signal based on the warning status signal, informing the staff of the risk associated with the audio information it emitted through the interaction module 404.

[0050] In yet another embodiment provided in this disclosure, such as Figure 1 As shown, the interaction module 404 includes a microphone 4041; the microphone 4041 is connected to the input interface of the voice coprocessor 401, and is used to collect sound information and transmit the sound information to the voice coprocessor 401.

[0051] In this embodiment, microphone 4041 captures sound information from the surrounding environment and transmits it to voice coprocessor 401, providing basic data for subsequent speech recognition. Microphone 4041 may also have noise reduction and speech enhancement functions, enabling it to filter out environmental noise and focus on speech within the received sound information. In practical applications, the microphone can be connected to the input interface of voice coprocessor 401 via an Inter-IC Sound (I2S) bus. The microphone converts the received sound information into digital audio data and transmits it to voice coprocessor 401 via the I2S bus.

[0052] In yet another embodiment provided in this disclosure, such as Figure 1 and Figure 2 As shown, the interaction module 404 includes: a speaker 4042, a display screen 4043, and an indicator light 4044; The speaker 4042 is connected to the first output interface of the main control chip 403, and is used to receive feedback signals and output voice prompt information. The display screen 4043 is connected to the second output interface of the main control chip 403, and is used to receive feedback signals and display the execution status of sound information, circuit breaker status and external circuit status. The indicator light 4044 is connected to the third output interface of the main control chip 403, and is used to receive feedback signals and indicate the opening and closing status of the circuit breaker through its own display method.

[0053] In this embodiment of the disclosure, the interaction module 404 may also consist of multiple audio-visual interaction devices. The signals in the feedback signals may be output as different audio-visual information by different interaction devices.

[0054] The speaker 4042 can output corresponding voice prompts based on the feedback signals transmitted from the main control chip 403, allowing staff to understand the execution status of voice commands and the operational results for circuit breaker 2. The first output interface can be a general-purpose input / output interface in the main control chip 403.

[0055] The display screen 4043 can show the execution status, circuit breaker status, and external circuit status through text and model examples. Operators can monitor the operation of the circuit breaker system and external circuits by viewing the display screen 4043. The second output interface can be a dedicated display interface of the main control chip 403, such as a Mobile Industry Processor Interface - Display Serial Interface (MIPI-DSI) or an embedded display port (eDP).

[0056] The display screen 4043 can also be used as an input interface for command information. Through the display screen 4043, corresponding control commands can be input to control the opening and closing of the circuit breaker when voice input is inconvenient.

[0057] Indicator light 4044 can indicate the opening and closing status of circuit breaker 2 through different display methods by changing the color of the light, making it easy for operators to quickly determine the status of the circuit breaker. The third output interface can be the general-purpose input / output interface in the main control chip 403.

[0058] In another embodiment provided in this disclosure, the circuit breaker 2 further includes: a moving contact and a stationary contact; The moving contact is connected to the output terminal of the circuit breaker 2 and is mechanically linked with the lever; the stationary contact is connected to the input terminal of the circuit breaker 2. The lever is used to push the moving contact to contact the stationary contact, so that the incoming end and the outgoing end are connected, the circuit breaker 2 is closed, and the external circuit is connected; and to pull the moving contact to separate it from the stationary contact, so that the incoming end and the outgoing end are disconnected, the circuit breaker 2 is opened, and the external circuit is turned off.

[0059] In this embodiment, the moving contact is controlled by a lever via mechanical linkage. When the lever changes position under the action of the drive assembly 3, it drives the moving contact to move synchronously. The stationary contact is fixedly connected to the input terminal of the circuit breaker 2 and connected to the power supply side of the external circuit. When the circuit breaker 2 is closed, the moving contact is in close contact with the stationary contact under the push of the lever, allowing current to flow from the input terminal to the output terminal, and the power supply side and load side of the external circuit are connected; at this time, the external circuit is in a conducting state, and the electrical equipment can work normally. When it is necessary to disconnect the circuit, the lever will move in the opposite direction, pulling the moving contact away from the stationary contact, thus disconnecting the external circuit and forming electrical isolation between the input terminal and the output terminal.

[0060] In another embodiment provided in this disclosure, the control circuit 5 includes a driver chip and a circuit sampling component; The driving chip is connected to the driving component 3 and the control interaction component 4 respectively, and is used to receive the electrical signal and send the driving signal to the driving component 3. The driving chip is also used to receive encoder signals sent by the driving component 3 and external circuit information sent by the circuit sampling component; and to send status information to the control interaction component 4.

[0061] In this embodiment of the disclosure, the driving signal can be a driving signal for a stepper motor, such as a pulse width modulation (PWM) signal. The driving chip can be a chip with stepper motor driving capability, which can generate a PWM signal based on the received electrical signal to adjust the movement of the stepper motor in the driving component.

[0062] After receiving the electrical signal generated by the main control chip 403, the control circuit 5 will output a corresponding PWM drive signal according to the characteristics of the electrical signal to control the power output of the motor and ensure that the motor can operate according to the preset parameters and requirements.

[0063] Simultaneously, the control circuit 5 can also receive encoder signals from the stepper motor encoder to obtain the motor's rotation amount. Based on the motor's rotation amount, the travel of the lever driven by the motor can be determined in real time, thereby determining the lever's position. Furthermore, the main control chip 403 can use this information to determine the contact status of the moving and stationary contacts, determine the opening and closing status of the circuit breaker 2, and thus obtain the circuit breaker's status.

[0064] The control circuit 5 may also include a circuit sampling component, which can detect information such as current, voltage and load of the external circuit in real time and use this information as external circuit information.

[0065] The driver chip can also send external circuit information and the status of the circuit breaker as status information to the control interaction component 4, which then determines the status of the external circuit and the status of the circuit breaker.

[0066] In another embodiment provided in this disclosure, the drive assembly 3 includes: a motor, a connecting rod, and a return spring; The motor is connected to the drive chip and is used to receive the drive signal and output power to drive the lever to change position through the linkage; the motor is also used to send encoder signals to the drive chip through the motor's encoder. The connecting rod is used to convert the rotational motion output by the motor into the linear motion of the connecting rod. The reset spring is used to store energy during the closing process and release energy during the opening process, so as to quickly disconnect the external circuit.

[0067] In this embodiment, the motor can be implemented as a stepper motor or a servo motor with forward and reverse rotation functions, and the power output is achieved by controlling the drive signal of the drive chip in the control circuit 5. The motor has an encoder, which can send encoder signals representing the amount of motor rotation to the drive chip.

[0068] A connecting rod can be a mechanical structure that converts rotary motion into linear motion, such as a crank-connecting rod mechanism or a rack and pinion mechanism. The linear motion of the connecting rod can drive the lever to change position, thereby controlling the opening and closing of circuit breaker 2.

[0069] A reset spring can be an elastic element with energy storage and release capabilities. During the closing process of circuit breaker 2, the reset spring is pulled open or compressed to store energy. When it is necessary to open the circuit, the reset spring releases the stored energy and quickly pulls the moving contact away from the stationary contact to achieve rapid disconnection of the external circuit.

[0070] In another embodiment provided in this disclosure, the circuit sampling component is connected to the driver chip and is used to collect external circuit information and transmit the external circuit information to the delivery driver chip.

[0071] In this embodiment of the disclosure, the circuit sampling component can be implemented as a component with current sampling and voltage sampling functions. For example, the current value of the external circuit can be sampled based on electromagnetic effects using a Hall current sensor; or the voltage value of the external current can be obtained using a voltage divider network.

[0072] In one possible implementation, the circuit sampling component can also sample data reflecting the circuit's state, such as temperature, phase, and frequency. For example, the temperature of the circuit can be sampled using a thermocouple; the phase of the external circuit can be sampled using a current transformer; or the phase of the external circuit can be sampled using a phase-locked loop, etc.

[0073] It should be noted that the more types of external circuit information sampled, the higher the accuracy of the prediction made by the security coprocessor 402, and the corresponding early warning and protection model needs to be adjusted.

[0074] In conjunction with the above, this disclosure also provides, as follows: Figure 3 The diagram illustrates a process for controlling a circuit breaker via voice. As shown, the voice information spoken by the operator is acquired by the interaction module 404 and output to the voice coprocessor 401. The voice coprocessor 401 extracts the circuit breaker control signal from the voice information, which is then further output to the safety coprocessor 402. The safety coprocessor 402 analyzes whether the circuit breaker control signal will trigger a warning based on the status information fed back from the control circuit and the intended operation of the signal. The main control chip 403 determines whether the circuit breaker control signal needs to be converted into an electrical signal and sent to the control circuit based on the execution signal, and then further controls the circuit breaker.
