Description

Technical Field

[0001] This invention relates to the technical field of circuit breaker control, and in particular to a control method and device for an intelligent integrated modular circuit breaker operating mechanism. Background Technology

[0002] Traditional circuit breaker spring operating mechanisms generally employ a distributed component control scheme, with various functional components scattered throughout the mechanism housing and electrically connected via complex flying wires. This traditional structure suffers from several inherent defects: the numerous wiring points between components and their complex connections make them highly susceptible to loose connections due to vibration or aging, directly impacting operational reliability. Furthermore, because the control function is achieved through a combination of multiple discrete components, maintenance personnel must rely on multimeters and other tools to systematically troubleshoot each component when a fault occurs, resulting in low fault location efficiency and requiring a high level of expertise from maintenance personnel. The existing mechanisms lack self-diagnostic capabilities, failing to provide early warnings or diagnoses for common faults such as motor stall, transmission chain failures, and abnormal insulation media, leading to lengthy power outages for each maintenance operation and severely impacting the continuous power supply reliability of the power system.

[0003] Most existing integrated solutions only achieve a compact physical layout, with significant shortcomings in intelligent control. They lack comprehensive awareness of the mechanism's operational status and cannot monitor key parameters such as ambient temperature and humidity, and the state of the insulation medium in real time. Safety protection mechanisms still rely on traditional hardware circuits, making accurate fault warnings and rapid protection difficult. Particularly in the drive control logic, a robust multi-dimensional safety verification mechanism has not yet been established, failing to effectively prevent misoperation and abnormal equipment operation. How to properly address these issues has become a pressing problem for the industry. Summary of the Invention

[0004] To address the aforementioned problems in the prior art, this invention provides a control method and device for an intelligent integrated modular circuit breaker operating mechanism. This significantly simplifies the wiring structure through modular integrated design, effectively avoiding the loose connection problems of traditional distributed components. By employing real-time status monitoring and multiple safety verification mechanisms, it achieves comprehensive perception and intelligent protection of the equipment's operating status. Furthermore, through dual hardware and software interlocking and rapid fault diagnosis functions, it greatly shortens maintenance time and improves power supply reliability and operation and maintenance efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A control method for an intelligent integrated modular circuit breaker operating mechanism is provided, applicable to an operating mechanism comprising a motor control module, a signal processing module, and a power supply module integrated via a fixed guide rail and connected via an aviation connector, including: S1, after power-on initialization, the motor control module collects external sensor signals and the internal circuit status of the operating mechanism through the signal processing module, and generates a real-time system state vector including environmental parameters, insulation medium status and mechanical energy storage status. S2, the motor control module calls the internal preset safety logic algorithm to compare and analyze the parameters in the real-time system state vector with the preset safety threshold, and generates an operation permission instruction indicating whether the current mechanism has the conditions for action based on the comparison result. S3, after receiving an external control command, the motor control module performs a logical AND verification between the external control command and the operation permission instruction. When the verification passes, it generates the corresponding drive coil or energy storage motor mechanism drive signal according to the type of the external control command. S4, while outputting the mechanism drive signal, the motor control module starts a real-time sampling circuit to monitor the current waveform and action duration of the drive circuit, and dynamically adjusts or interrupts the mechanism drive signal according to the monitoring results to enter a safety protection state.

[0006] Furthermore, in S3, when the mechanism drive signal is used to drive the energy storage motor, it includes: S31, the motor control module responds to a signal indicating that the spring is not stored in energy by outputting a continuous drive voltage for the energy storage motor; S32, during the output drive voltage process, the motor circuit current is sampled in real time. If the sampled current continues to be higher than the preset stall threshold after the start-up shielding time has passed, the motor is determined to be in a mechanical stall state. S33 starts the timer the instant the output drive voltage is applied. If the drive duration exceeds the preset maximum energy storage time limit, the motor drive chain is determined to be faulty. S34, if a mechanical stall condition or a motor drive chain failure is detected, the motor control module immediately cancels the mechanism drive signal and locks the output.

[0007] Furthermore, in S1, generating the real-time system state vector includes: S11, the motor control module reads the ambient temperature and humidity values ​​and updates them to the real-time system state vector; S12, the motor control module compares the real-time system state vector with a preset temperature and humidity threshold group, which includes a low temperature limit, a high humidity limit, a heating stop temperature, and a safe humidity limit. S13, when the ambient temperature is less than the low temperature limit or the humidity is greater than the high humidity limit, the motor control module executes the set heating control flag to start the heater; S14, when the combined conditions are met, the ambient temperature is greater than the heating stop temperature and the humidity is less than the safe humidity limit, the motor control module executes the reset heating control flag to stop the heater, thereby preventing insulation condensation caused by the temperature rising but the humidity not decreasing.

[0008] Furthermore, in S2, the operation permission instruction is generated, including: S21, the motor control module extracts the gas density value from the real-time system state vector; S22, if the gas density value is lower than the preset alarm threshold, the motor control module sets the operation permission instruction to a global lockout state in the software logic layer; S23, the motor control module drives the internally integrated re-operation relay to operate, and directly cuts off the power supply circuit to the opening coil and closing coil through the normally closed physical contact of the re-operation relay, thereby achieving dual hardware and software interlocking.

[0009] Furthermore, in S3, before generating the mechanism drive signal, the following steps are also included: S35, the motor control module detects whether there are parallel closing and opening signals at the input terminal; S36 If the closing signal is detected to be present at the same time as the first opening signal or the second opening signal, the motor control module shall respond to the opening signal first and forcibly block the closing logic until the closing signal is reset, thereby ensuring that the circuit breaker will not continuously open and close when the mechanism drive signal is generated.

[0010] Furthermore, in S4, after entering the safety protection state, it includes: S41, the motor control module queries the corresponding fault code in its internal memory according to the specific triggering source that caused it to enter the safety protection state. The specific triggering source includes motor overcurrent, energy storage timeout or low gas pressure. S42, the motor control module transmits the fault code to the digital tube display panel located on the surface of the operating mechanism housing via a communication bus; S43, the display panel displays the fault code in a flashing manner, and the motor control module maintains the display state until it receives a manual reset signal, which serves as a prerequisite for releasing the safety protection state.

[0011] This invention also provides a control device for an intelligent integrated modular circuit breaker operating mechanism, applied to an operating mechanism comprising a motor control module, a signal processing module, and a power supply module integrated via a fixed guide rail and connected via an aviation connector, including: The generation module is used to generate a real-time system state vector containing environmental parameters, insulation medium status and mechanical energy storage status by acquiring external sensor signals and the internal circuit status of the operating mechanism through the signal processing module after the motor control module is powered on and initialized. The analysis module is used by the motor control module to call the internal preset safety logic algorithm to compare and analyze the parameters in the real-time system state vector with the preset safety threshold, and generate an operation permission instruction indicating whether the current mechanism has the conditions for action based on the comparison result. The verification module is used to perform a logical AND verification between the external control command and the operation permission instruction after the motor control module receives the external control command. When the verification passes, the module generates the corresponding drive signal for the drive coil or energy storage motor according to the type of the external control command. The adjustment module is used to activate a real-time sampling circuit to monitor the current waveform and action duration of the drive circuit while the motor control module outputs the mechanism drive signal, and dynamically adjust or interrupt the mechanism drive signal to enter a safety protection state based on the monitoring results.

[0012] Furthermore, the generation module, the analysis module, the verification module, and the adjustment module are controlled to execute the control method of the intelligent integrated modular circuit breaker operating mechanism described above.

[0013] The present invention also provides an electronic device, which includes: a communication interface, a processor, and a memory; The memory is used to store program instructions, which, when executed by the processor that is connected to the memory via the communication interface, implement the control method of the intelligent integrated modular circuit breaker operating mechanism described above.

[0014] The present invention also provides a computer-readable storage medium storing computer program instructions, which, when executed by a computer (e.g., a processor in a computer), implement the control method for the intelligent integrated modular circuit breaker operating mechanism described above.

[0015] This invention improves the reliability and safety of circuit breaker operating mechanisms through modular integration and intelligent control; the integrated module design significantly simplifies the wiring structure and effectively avoids loose connection faults; through real-time system status monitoring and multiple safety verification mechanisms, it achieves comprehensive perception and intelligent protection of equipment operating status; and it establishes dual hardware and software interlocking and rapid fault diagnosis functions, shortening maintenance time and improving power supply reliability. Thus, it solves the defects of traditional distributed structures, such as difficult maintenance and lack of self-testing capabilities, and has comprehensive advantages of convenient installation, efficient operation and maintenance, and safety and reliability.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific preferred embodiments, but this does not limit the scope of protection of the present invention.

[0019] like Figure 1 As shown, this embodiment provides a control method for an intelligent integrated modular circuit breaker operating mechanism, applied to an operating mechanism comprising a motor control module, a signal processing module, and a power supply module integrated via a fixed guide rail and connected via an aviation plug. The control method for this intelligent integrated modular circuit breaker operating mechanism includes: In step S1, after the motor control module is powered on and initialized, it collects external sensor signals and the internal circuit status of the operating mechanism through the signal processing module to generate a real-time system state vector that includes environmental parameters, insulation medium status and mechanical energy storage status. In step S2, the motor control module calls the internal preset safety logic algorithm to compare and analyze the parameters in the real-time system state vector with the preset safety threshold, and generates an operation permission instruction indicating whether the current mechanism has the conditions for action based on the comparison result. In step S3, after receiving an external control command, the motor control module performs a logical AND verification between the external control command and the operation permission instruction. When the verification passes, it generates the corresponding drive coil or energy storage motor mechanism drive signal according to the type of the external control command. In step S4, while outputting the mechanism drive signal, the motor control module starts a real-time sampling loop to monitor the current waveform and action duration of the drive circuit, and dynamically adjusts or interrupts the mechanism drive signal according to the monitoring results to enter a safety protection state.

[0020] In one embodiment, an integrated modular control method is provided, featuring comprehensive state awareness, intelligent safety verification, and rapid fault diagnosis. The core lies in replacing traditional distributed components with an integrated design of microcontrollers and electronic devices, achieving modularity, intelligence, and high reliability of the operating mechanism. A physical diagram of this intelligent integrated modular circuit breaker operating mechanism is shown below. Figure 7a and 7b As shown. The operating mechanism mainly includes a housing (7), a fixed guide rail (1), a control module display panel (2), control buttons (3), indicator lights (4), an inspection cover (5), an aviation plug (6), a motor control module (8), a signal processing module (9), a power supply module (10), and a signal module (11). The front view of the intelligent integrated modular circuit breaker operating mechanism is shown in the attached figure. Figure 8 As shown, a side view of the intelligent integrated modular circuit breaker operating mechanism is attached. Figure 9As shown. The enclosure (7) is made of polyvinyl chloride injection molding and the surface is treated with a protective coating to enhance corrosion resistance and insulation performance. Each module is integrated into the enclosure through a fixed guide rail (1) and externally connected through an aviation plug (6). This plug-in design simplifies wiring, reduces the risk of loose connections, and facilitates maintenance and replacement. The control system consists of a motor control module (8), a signal processing module (9), a power supply module (10), and a signal module (11). The motor control module (8) is the core and is responsible for overall coordination and control; the signal processing module (9) is used to collect and process sensor data; the power supply module (10) provides a stable power supply; and the signal module (11) processes external communication signals.

[0021] During the power-on initialization phase of the operating mechanism, a self-test process is executed. After the motor control module (8) starts, the signal processing module (9) collects signals from external sensors (such as temperature sensors, humidity sensors, position sensors, etc.) and the status parameters of the internal circuit of the operating mechanism. These parameters include ambient temperature and humidity, insulation medium status, mechanical energy storage position, power phase sequence, etc. The control circuit of this intelligent integrated modular circuit breaker operating mechanism is shown in the attached figure. Figure 10 As shown. The collected data is integrated to generate a real-time system state vector, which comprehensively reflects the current operating conditions of the mechanism. At the same time, the power module (10) performs phase loss and phase sequence detection to ensure normal power supply; if an abnormality is detected, the control module display panel (2) will immediately display the corresponding fault code, such as "E01" indicating a power phase loss and "E02" indicating a phase sequence error, which is convenient for maintenance personnel to quickly identify the problem. After the self-test is completed, the system enters the standby state, and the indicator light (4) indicates the ready state.

[0022] Based on the real-time system state vector, the motor control module (8) calls the internally preset safety logic algorithm to perform state evaluation and operation permission generation. The safety logic algorithm compares and analyzes the parameters in the state vector (such as ambient temperature, insulation resistance, energy storage spring position, motor current reference value, etc.) with preset safety thresholds. For example, if the ambient temperature exceeds the set upper limit (such as 85°C) or the insulation resistance is lower than the minimum allowable value (such as 1MΩ), the algorithm will determine that the mechanism is in a high-risk state and generate an instruction to prohibit operation; otherwise, if all parameters are within the safe range, an operation permission instruction will be generated. This instruction is processed in conjunction with external control commands (such as opening and closing signals from remote console or local buttons) through a logic AND verification mechanism. Specifically, after receiving an external control command, the motor control module (8) performs a logic AND operation with the operation permission instruction, and only allows the subsequent action to be executed when both are valid.

[0023] After the external control command passes the logic AND check, the motor control module (8) generates the corresponding mechanism drive signal according to the command type. For example, for the closing operation, the module outputs the excitation signal of the drive coil; for the opening or energy storage operation, it controls the forward and reverse rotation of the energy storage motor. The drive signal is transmitted to the external actuator through the aviation connector (6), and at the same time, the motor control module (8) starts the real-time sampling circuit to continuously monitor the current waveform and action duration of the drive circuit. The sampling circuit uses a high-precision current sensor and timer to capture the current peak, waveform distortion and operation time data in real time. If the current exceeds the preset overcurrent threshold (e.g., 120% of the motor's rated current) or the action time exceeds the reasonable range (e.g., energy storage timeout), the motor control module (8) will dynamically adjust the drive signal, such as reducing the output power or interrupting the signal, so that the mechanism enters the safety protection state. In addition, the system has dedicated alarm functions for energy storage overcurrent and energy storage timeout. Once triggered, the control module display panel (2) will display specific fault codes (such as "F01" for overcurrent and "F02" for timeout) and send alarm information to the background through the signal module (11) to achieve remote monitoring.

[0024] During operation, the operating mechanism implements multiple protection and self-test functions through integrated design. The motor control module (8) continuously monitors the status of the motor circuit, including phase loss, overcurrent, and abnormal phase sequence, and, in conjunction with the data from the signal processing module (9), diagnoses the status of mechanical components (such as limit switches). For example, when the energy storage mechanism jams, the module detects an abnormal rise in current and immediately interrupts the drive to prevent equipment damage. At the same time, temperature and humidity control components are integrated into the module to automatically adjust the environment inside the box and prevent condensation or overheating. All fault information is displayed through a digital tube and supports historical data recording for easy later analysis. All external connections use heavy-duty connectors, simplifying wiring and improving anti-interference capabilities.

[0025] This embodiment improves the reliability and safety of the circuit breaker operating mechanism through modular integration and intelligent control. The integrated modular design significantly simplifies the wiring structure and effectively avoids loose connections. Real-time system status monitoring and multiple safety verification mechanisms enable comprehensive perception and intelligent protection of the equipment's operating status. The establishment of dual hardware and software interlocking and rapid fault diagnosis functions shortens maintenance time and improves power supply reliability. It overcomes the shortcomings of traditional distributed structures, such as difficult maintenance and lack of self-testing capabilities, and offers comprehensive advantages including convenient installation, efficient operation and maintenance, and high reliability.

[0026] Preferred, such as Figure 2 As shown, in step S3, when the mechanism drive signal is used to drive the energy storage motor, this embodiment includes steps S31-S34 as follows: In step S31, the motor control module responds to a signal indicating that the spring is not energized by outputting a continuous drive voltage for the energy storage motor. In step S32, during the output of the drive voltage, the motor circuit current is sampled in real time. If the sampled current continues to be higher than the preset stall threshold after the start-up shielding time has passed, the motor is determined to be in a mechanical stall state. In step S33, a timer is started at the instant the drive voltage is output. If the drive duration exceeds the preset maximum energy storage time limit, the motor drive chain is determined to be faulty. In step S34, if a mechanical stall condition or a motor drive chain failure is detected, the motor control module immediately cancels the mechanism drive signal and locks the output.

[0027] When the operating mechanism needs to perform spring energy storage operation, the motor control module (8) continuously monitors the status of the limit switch linked with the spring mechanism through the signal processing module (9). When a signal indicating that the spring is not stored (e.g., the limit switch is in the "open" position) is received, the motor control module (8) immediately applies a continuous drive voltage to the energy storage motor through its output port to start the energy storage process.

[0028] During motor drive, the operating current is monitored in real time by a current sampling circuit (such as a Hall sensor) integrated in the motor circuit. To accurately distinguish between normal starting inrush current and abnormal stall current, a short starting current shielding time (e.g., 100-300 milliseconds) is preset in the control logic. If the effective value of the sampled current continues to exceed the preset stall threshold (which is usually set to 150%-200% of the rated operating current of the motor) after this shielding time has passed, the algorithm built into the motor control module (8) will determine that the motor is in a stall state due to mechanical jamming. At the same time, the hardware timer or software timer that starts instantaneously from the output of the drive voltage will start working. If the duration of the drive state exceeds the preset maximum energy storage time limit (e.g., 10-15 seconds), it is determined that there is a fault in the motor transmission chain, such as gearbox damage or transmission mechanism disengagement. Once any of the above fault conditions are triggered, it is determined to be mechanical stall or transmission chain timeout, and the protection mechanism of the motor control module (8) will be activated immediately, which will forcibly cancel the output mechanism drive signal, cut off the power supply to the energy storage motor, and enter the output lockout state. In this locked state, the module will refuse to execute any new drive commands until maintenance personnel manually reset it via control button (3) or remote command. At the same time, the specific fault type (such as "E03" representing stall and "E04" representing energy storage timeout) will be displayed intuitively on the digital tube on the control module display panel (2), and may be accompanied by specific flashing of the indicator light (4), thereby realizing rapid fault location and handling, improving the efficiency of system maintenance and the safety of operation.

[0029] Preferred, such as Figure 3 As shown, in step S1, the generation of the real-time system state vector, in this embodiment, further includes the following steps S11-S14: In step S11, the motor control module reads the ambient temperature and humidity values ​​and updates them to the real-time system state vector; In step S12, the motor control module compares the real-time system state vector with a preset temperature and humidity threshold group, which includes a low temperature limit, a high humidity limit, a heating stop temperature, and a safe humidity limit. In step S13, when the ambient temperature is less than the low temperature limit or the humidity is greater than the high humidity limit, the motor control module executes the set heating control flag to start the heater. In step S14, when the combined conditions of ambient temperature being greater than heating stop temperature and humidity being less than safe humidity limit are met, the motor control module executes a reset heating control flag to stop the heater, thereby preventing insulation condensation caused by temperature rise but humidity not drop.

[0030] The temperature and humidity monitoring system uses the motor control module (8) as the control core. The signal processing module (9) periodically reads the measured values ​​of the temperature and humidity sensors integrated inside the housing (7) and updates the acquired ambient temperature and humidity values ​​to the system state vector in real time, thereby forming a continuous digital mapping of the operating environment of the mechanism.

[0031] To achieve effective environmental control, the internal memory of the motor control module (8) pre-stores a set of calibrated temperature and humidity thresholds. Specifically, this threshold set includes: a low-temperature limit (e.g., 5°C) and a high-humidity limit (e.g., 85% relative humidity) for determining whether heating needs to be started; and a heating stop temperature (e.g., 15°C) and a safe humidity limit (e.g., 70% relative humidity) for determining whether heating can be stopped. The control module logically compares the temperature and humidity data in the real-time system state vector with this threshold set to make accurate control decisions.

[0032] When the system status vector shows that the ambient temperature is less than the low temperature limit or the ambient humidity is greater than the high humidity limit, it indicates a risk of condensation or a potential low-temperature operation hazard. The motor control module (8) then executes the operation of setting the heating control flag. This flag outputs a drive signal through the signal module (11) to start the heater installed in the mechanism housing and begin heating and dehumidifying the area around the key electrical components. When the system detects that the ambient temperature is greater than the heating stop temperature and the ambient humidity is less than the safe humidity limit, the motor control module (8) will execute the operation of resetting the heating control flag, thereby turning off the heater. This prevents the heating from being blindly stopped when the temperature has risen but the humidity has not yet dropped below the safe limit (for example, during the rainy season when the temperature rises but the humidity is still extremely high). This avoids the condensation of water vapor on the surface of the insulating medium due to the premature shutdown of the heater and the temperature difference between the inside and outside of the housing, thus fundamentally eliminating insulation condensation accidents.

[0033] Preferred, such as Figure 4 As shown, in step S2, the operation license instruction is generated. This embodiment also includes the following steps S21-S23: In step S21, the motor control module extracts the gas density value from the real-time system state vector; In step S22, if the gas density value is lower than the preset alarm threshold, the motor control module sets the operation permission instruction to a global lockout state in the software logic layer. In step S23, the motor control module drives the internally integrated re-operation relay to operate, and directly cuts off the power supply circuit to the opening coil and the closing coil through the normally closed physical contact of the re-operation relay, thereby achieving dual hardware and software interlocking.

[0034] The operating mechanism implements mandatory interlocking protection based on the state of the insulating medium. The motor control module (8) continuously extracts the gas density value monitored by the dedicated density sensor or pressure sensor from the real-time system state vector. After analog-to-digital conversion and filtering by the signal processing module (9), the gas density value is transmitted in real time to the core processing unit of the motor control module (8). If, after comparison, the gas density value is lower than the preset alarm threshold (this threshold is usually set according to the circuit breaker model at the critical density or pressure value to ensure normal breaking performance), the motor control module (8) will execute the highest priority protection instruction in its software logic layer and forcibly set the operation permission instruction to a global interlocking state. The software-level interlocking will cause the module to refuse to respond to any external remote or local opening or closing commands.

[0035] To achieve absolutely reliable protection, a hardware-level forced disconnection is introduced. Simultaneously with the software-set interlock state, the motor control module (8) drives an integrated reclosing relay. The normally closed physical contact of the relay is connected in series to the main power supply circuit leading to the opening and closing coils. The relay's operation directly causes its normally closed contact to open, thus physically cutting off the current path of the drive coil, forming a dual software and hardware interlocking mechanism combining software logic interlocking and physical disconnection. Even if the control system software experiences extreme anomalies, the physical contact disconnection serves as the final safety barrier, completely preventing major accidents that might occur during live opening and closing operations when the insulation medium density is insufficient.

[0036] Preferred, such as Figure 5 As shown, before generating the mechanism drive signal in step S3, this embodiment further includes the following steps S35-S36: In step S35, the motor control module detects whether there are parallel closing and opening signals at the input terminal; In step S36, if the closing signal and the first opening signal or the second opening signal are detected to exist simultaneously, the motor control module responds to the opening signal first and forcibly blocks the closing logic until the closing signal is reset, thereby ensuring that the circuit breaker will not continuously open and close when the mechanism drive signal is generated.

[0037] Before generating any mechanism drive signal, the motor control module (8) continuously scans and detects the status of multiple command inputs from the remote control terminal, local control button (3), and protection device through its high-speed input port. In particular, it makes real-time judgments on whether there is electrical parallelism or logical overlap between the closing signal, the first opening signal (usually from relay protection), and the second opening signal (usually from backup protection or manual emergency opening). When the detection logic of the motor control module (8) identifies that the closing signal and either the first or second opening signal are simultaneously valid, the system will immediately activate the preset highest priority safety strategy. In this case, the control module will unconditionally prioritize the opening signal and immediately enter the opening operation preparation process. At the same time, the program inside the module will execute a forced command to block the closing logic, so that the closing control loop is disabled at the software level.

[0038] The closing logic block state will be maintained until the external closing signal is withdrawn and returns to an invalid level. Only then will the motor control module (8) release the block on the closing logic, allowing the system to restore its normal multi-command response capability. The signal interlocking mechanism fundamentally eliminates the continuous jumping action of the circuit breaker due to signal competition or interference, avoiding serious accidents such as severe breakdown, overheating of the current-carrying circuit, or even explosion that may be caused by the switchgear being subjected to continuous interruption of large currents in a short period of time.

[0039] Preferred, such as Figure 6 As shown, in step S4, after entering the safety protection state, this embodiment includes the following steps S41-S43: In step S41, the motor control module queries the corresponding fault code in its internal memory according to the specific triggering source that caused it to enter the safety protection state. The specific triggering source includes motor overcurrent, energy storage timeout, or low gas pressure. In step S42, the motor control module transmits the fault code to the digital tube display panel located on the surface of the operating mechanism housing via a communication bus; In step S43, the display panel displays the fault code in a flashing manner, and the motor control module maintains the display state until it receives a manual reset signal, which serves as a prerequisite for releasing the safety protection state.

[0040] When the operating mechanism enters a safety protection state due to a specific fault, the motor control module (8) accurately identifies the specific trigger source that caused the entry into the safety protection state. The trigger source includes, but is not limited to, motor overcurrent, energy storage timeout, or low gas pressure. It queries the pre-stored fault code corresponding to the above trigger source in its internal non-volatile memory (for example, "F10" corresponds to motor overcurrent, "F11" corresponds to energy storage timeout, and "F12" corresponds to low gas pressure) to complete the digital calibration of the fault type. In order to provide clear and persistent fault indication to the operators and maintenance personnel, the motor control module (8) transmits the specific fault code data queried in real time to the digital tube display panel (2) located on the surface of the operating mechanism housing through its integrated communication bus (such as I2C or SPI bus). The display panel is specially configured to display the received fault code in a flashing manner. The motor control module (8) will maintain this flashing display state and lock the operating mechanism in a safe protection state until it detects a valid manual reset signal from the control button (3) or a specific reset port, ensuring that the warning information will not disappear before the fault is actively confirmed and processed, and that the mechanism cannot be remotely or automatically resumed to operation.

[0041] Figure 11 The diagram shows a control device for an intelligent integrated modular circuit breaker operating mechanism according to an exemplary embodiment. This device is applied to an operating mechanism comprising a motor control module, a signal processing module, and a power supply module integrated via a fixed guide rail and connected via an aviation connector. Figure 11 As shown, the control device of the intelligent integrated modular circuit breaker operating mechanism includes a generation module 1101, an analysis module 1102, a verification module 1103, and an adjustment module 1104.

[0042] The generation module 1101 is used by the motor control module after power-on initialization to collect external sensor signals and the internal circuit status of the operating mechanism through the signal processing module to generate a real-time system state vector containing environmental parameters, insulation medium status and mechanical energy storage status. The analysis module 1102 is used by the motor control module to call the internal preset safety logic algorithm to compare and analyze the parameters in the real-time system state vector with the preset safety threshold, and generate an operation permission instruction indicating whether the current mechanism has the conditions for action based on the comparison result. The verification module 1103 is used to perform a logical AND verification between the external control command and the operation permission instruction after the motor control module receives the external control command. When the verification passes, the module generates the corresponding drive signal for the drive coil or energy storage motor according to the type of the external control command. The adjustment module 1104 is used by the motor control module to start a real-time sampling circuit to monitor the current waveform and action duration of the drive circuit while outputting the mechanism drive signal, and to dynamically adjust or interrupt the mechanism drive signal to enter a safety protection state based on the monitoring results.

[0043] The generation module 1101, analysis module 1102, verification module 1103, and adjustment module 1104 included in the block diagram of the control device for the intelligent integrated modular circuit breaker operating mechanism are controlled to execute the control method for the intelligent integrated modular circuit breaker operating mechanism described in any of the above embodiments.

[0044] like Figure 12 As shown, this embodiment provides an electronic device 1200, which includes: a communication interface, a processor 1201, and a memory 1202; The memory 1202 stores program instructions. When these instructions are executed by the processor 1201, which is connected to the memory 1202 via the communication interface, the motor control module, after power-on initialization, collects external sensor signals and the internal circuit status of the operating mechanism through the signal processing module to generate a real-time system state vector containing environmental parameters, insulation medium status, and mechanical energy storage status. The motor control module calls an internally preset safety logic algorithm to compare and analyze each parameter in the real-time system state vector with a preset safety threshold. Based on the comparison result, it generates an operation permission instruction indicating whether the current mechanism has the conditions for action. After receiving an external control command, the motor control module performs a logical AND check between the external control command and the operation permission instruction. When the check passes, it generates a corresponding mechanism drive signal for the drive coil or energy storage motor based on the type of the external control command. While outputting the mechanism drive signal, the motor control module starts a real-time sampling loop to monitor the current waveform and action duration of the drive circuit, and dynamically adjusts or interrupts the mechanism drive signal to enter a safety protection state based on the monitoring results.
