[0001] This invention relates to the field of intelligent assistive devices technology, and in particular to an Internet of Things (IoT) smart miniature circuit breaker. Background Technology

[0002] With the deep integration of IoT technology and smart power distribution systems, the demand for intelligent and remote management of power distribution safety in scenarios such as industrial production and home life continues to upgrade. As the core protection component of power distribution circuits, miniature circuit breakers are transforming their operation mode from traditional manual on-site operation to remote intelligent control. Especially in large building complexes, industrial plants, and remote power distribution areas, remote monitoring and rapid response have become key requirements for ensuring the stable operation of power distribution systems.

[0003] Existing miniature circuit breakers (MCBs) suffer from significant technical bottlenecks: some remote-controlled products place the control system on both sides of the circuit breaker, resulting in reduced installation density; the transmission structure uses direct drive or simple gear transmission, leading to insufficient transmission accuracy and high impact loads, which can easily cause false triggering; at the same time, they lack the ability to coordinate and manage multiple devices, failing to meet the clustered safety protection requirements of complex power distribution circuits. To address these issues and meet the comprehensive requirements of intelligent power distribution systems for circuit breaker layout rationality, control precision, power supply reliability, and coordination, this solution has been developed.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] See Figures 1 to 8 This invention discloses an IoT-enabled smart miniature circuit breaker, comprising a miniature circuit breaker body 1. A control chamber 2 and a core chamber are sequentially installed from top to bottom at the front end of the miniature circuit breaker body 1. This layout avoids occupying space on both sides of the circuit breaker, ensuring installation density consistent with traditional miniature circuit breakers. The core chamber includes an upper drive chamber 3, a lower drive chamber 4, and a connecting chamber 5 connecting the upper drive chamber 3 and the lower drive chamber 4. The core chamber adopts a dual-drive combined connecting structure. The upper drive chamber 3 and the lower drive chamber 4 are mechanically and electrically connected through the connecting chamber 5. A shielded cable channel is provided inside the connecting chamber 5 to reduce electromagnetic interference between the components of the two drive chambers and to provide a neat path for component wiring. Furthermore, a lifting control component is vertically installed on the other side of the core chamber by bolt fixing, forming spatial isolation with the battery 6 on the bottom of the core chamber, preventing mutual interference between the power supply component and the transmission component, and improving the operational stability of the equipment. The PCB board inside the control chamber 2 adopts a four-layer wiring design, integrating five functional modules of the IoT communication platform. The edge of the PCB board has pre-set connecting holes and inlet holes: the connecting holes establish signal connections with components such as motor 12 and sensors in the core chamber through gold-plated probes, with a contact resistance ≤5mΩ; the inlet holes have built-in waterproof connectors to support sealed access of external power cables and communication cables. The PCB board inside control chamber 2 integrates an IoT communication platform, which includes a remote signal receiving module, an instruction parsing module, a drive control module, a status feedback module, and a backup power management module. The PCB board establishes a signal connection with the core chamber components through connecting holes and realizes external power supply and signal transmission through inlet holes. The modules work together to realize signal transmission, instruction processing, mechanism drive, status feedback, and power supply switching functions. Each module interacts with the other via an SPI communication bus on the PCB board, with a communication rate of 1-10 Mbps, meeting the real-time requirements for command transmission and status feedback. The collaborative process follows a closed-loop logic consisting of signal reception, command parsing, mechanism driving, status acquisition, and feedback transmission. The power supply switching function is led by the backup power management module, which triggers a switching command when the external power supply is abnormal, ensuring uninterrupted operation of the entire system.

[0023] Specifically, the corresponding side walls of the upper drive chamber 3 and the lower drive chamber 4 are provided with heat dissipation structures; multiple batteries 6 are installed at equal intervals on one side of the bottom surface of the core chamber; multiple heat dissipation slots are opened at equal intervals on one side of the front end of the upper drive chamber 3 and the rear end of the lower drive chamber 4; the batteries 6 are electrically connected to the backup power management module; and the motor 12 is electrically connected to the drive control module.

[0024] Specifically, the remote signal receiving module adopts a modular design, integrating a wired communication interface (RJ45) and a wireless communication module (WiFi / Bluetooth / LoRa). The communication method can be selected according to the application scenario: wired communication is suitable for fixed scenarios such as industrial plants, with a transmission distance of ≤100m; wireless communication is suitable for remote areas or mobile monitoring scenarios, with a transmission distance of ≤3km in LoRa mode and ≤100m in WiFi / Bluetooth mode. It is used to receive on / off control commands and status query commands sent by remote control terminals, and is connected to the command parsing module to transmit the received commands to the command parsing module.

[0025] Specifically, the instruction parsing module has a built-in signal processing unit, which is used to decode, verify and parse the instructions transmitted by the remote signal receiving module to generate standardized driving instructions. The instruction parsing module is connected to the drive control module and the status feedback module respectively, and can issue driving instructions and receive status feedback data.

[0026] It should be added that after the instruction parsing module completes the decoding, verification and parsing of the instruction, it will also combine the real-time equipment operating status data transmitted by the status feedback module, and adjust the execution parameters of the standardized drive instruction through the instruction dynamic optimization strategy to generate the target drive instruction adapted to the current equipment operating status; the equipment operating status data includes the real-time load of the motor, the displacement deviation of the lifting screw, and the power supply stability of the battery. The instruction dynamic optimization strategy employs a weighted feedback optimization algorithm, and the formula for calculating the target execution parameters is as follows: ,in, These are the execution parameters for the target driver instruction. The basic execution parameters for standardized driver instructions, For dynamic optimization coefficients; The dynamic optimization coefficients are calculated by weighting the state data, and the formula is as follows: a, b, and c are the weighting coefficients corresponding to the state data. This is the normalized value of the motor's real-time load. This is the normalized value of the displacement deviation of the lifting screw. Normalized value for the stability of battery power supply; The target-driven instructions are executed through the drive control module. During execution, real-time execution feedback data transmitted by the status feedback module is received synchronously, and the feedback data is substituted into the weighted feedback optimization algorithm for recalculation. ,right The process is iteratively corrected until the displacement deviation of the lifting screw and the stability of motor operation meet the preset control requirements, thus completing the closed-loop adjustment.

[0027] Specifically, the drive control module receives drive commands from the command parsing module and controls the start, stop, direction and operating parameters of the motor 12; the drive control module is equipped with an overload protection unit to prevent the motor 12 from operating under overload.

[0028] Specifically, the status feedback module integrates a position sensor and a status monitoring unit. The position sensor is used to collect the displacement status of the lifting screw 14 and the on / off status of the miniature circuit breaker body 1. The status monitoring unit is used to collect the operating parameters of the motor 12 and the power status of the battery 6. The status feedback module transmits the collected status data to the instruction parsing module, which processes it and then transmits it back to the remote control terminal.

[0029] It should be noted that the backup power management module is used to monitor the external power supply status, and can realize the automatic switching between external power supply and battery 6 power supply, and control the charging of battery 6 when the external power supply is restored; the backup power management module is equipped with a low power alarm unit, which is used to send an alarm signal when the battery 6 power is lower than a preset threshold.

[0030] Specifically, the lifting control component includes a vertically arranged I-beam structure lifting platform 7, with teeth spaced apart along the height direction on opposite sides of the lifting platform 7; the lifting platform 7 is slidably connected to a lifting block 8 adapted to its structure, the lifting block 8 has an L-shaped cross-section, and a positioning groove is provided at the end away from the lifting platform 7, a rotating groove is provided inside the positioning groove, and a positioning block 9 is rotatably connected in the rotating groove, with torsion springs sleeved on both sides of the positioning block 9, the torsion springs providing elastic force to the positioning block 9, so that the positioning block 9 engages with the teeth.

[0031] Specifically, a lifting box 10 is mounted on the top surface of the lifting block 8. The inner cavity of the lifting box 10 is provided with a circular limiting block. The inner end of the limiting block is provided with a lifting hole that penetrates the lifting box 10, the bottom surface of the upper drive chamber 3, and the top surface of the lower drive chamber 4. A worm gear 11 is rotatably connected to the other side of the inner cavity of the lifting box 10. The top and bottom surfaces of the worm gear 11 are provided with limiting grooves that engage with the limiting block. The top surface of the worm gear 11 is provided with a threaded hole concentric with the lifting hole. The worm gear 11 is threadedly connected to a lifting screw 14 that engages with the threaded hole. A motor 12 is installed at the rear end of the other side of the inner cavity of the lifting box 10. The output shaft of the motor 12 is connected to a worm 13 that engages with the worm gear 11 through a coupling.

[0032] Specifically, the IoT communication platform also integrates a distributed communication coordination module. This module is bidirectionally interconnected with the remote signal receiving module and the status feedback module to enable data exchange and control command coordination among multiple miniature circuit breakers. The operational status data includes on / off status, load current, fault type, and fault occurrence time. After receiving fault status signals from other circuit breakers, the distributed communication coordination module calculates the linkage response level using a linkage control priority algorithm, generates a linkage control strategy based on local operational status data, and synchronously adjusts the operational status of the device through the drive control module to achieve clustered safety management of the power distribution circuit.

[0033] The formula for the linkage control priority algorithm is as follows: Where P is the linkage response priority, α, β, and γ are the weights corresponding to the fault level, load factor, and power distribution circuit correlation degree, respectively, L is the fault level of other circuit breakers, K is the current load factor of this equipment, and R is the power distribution circuit correlation degree between this equipment and the faulty circuit breaker; according to the value range of priority P, the preset linkage control strategy is matched to generate the corresponding on / off control command or load adjustment command.

[0034] Specifically, the distributed communication coordination module has a built-in communication link redundancy switching mechanism, pre-setting a primary communication link and a backup communication link, and monitoring the transmission quality of the two links in real time through a link quality monitoring algorithm. The link quality monitoring algorithm includes bit error rate calculation and transmission delay detection, and the bit error rate calculation formula is as follows: The transmission delay detection formula is: Where BER is the link bit error rate. This represents the number of erroneous data frames during transmission. The total number of data frames transmitted. For transmission delay, For the time of data reception, The time when the data was sent;

[0035] When the main communication link satisfies or When necessary, the system automatically switches to a backup communication link to maintain data interaction. The switching process employs a seamless link switching mechanism, first establishing a backup link connection and synchronizing the current transmission context, then interrupting the primary link transmission to ensure the normal execution of control commands and the continuous transmission of status data. To preset the bit error rate threshold, This is the preset transmission delay threshold.

[0036] This invention achieves remote intelligent control, clustered collaborative management and control, and reliable operation of miniature circuit breakers through the coordinated operation of an Internet of Things (IoT) communication platform and a mechanical transmission structure. The specific working principle is as follows: Before the equipment is put into use, initialization and debugging must be completed: manually adjust the lifting block 8 in the lifting control component so that it slides along the H-shaped lifting platform 7 to the preset height. At this time, the positioning block 9 is tightly engaged with the teeth on the lifting platform 7 under the elastic force of the torsion spring, realizing the positioning and locking of the lifting block 8 and the lifting box 10 mounted on the top surface, and preventing accidental displacement during operation. At the same time, the backup power management module monitors the external power supply status in real time and establishes a power switching link between the external power supply and the battery 6 to ensure the continuity of power supply to the equipment.

[0037] During remote control, the on / off control commands or status query commands sent by the remote control terminal are transmitted to the remote signal receiving module via wired or wireless communication. After the commands are transmitted from the remote signal receiving module to the command parsing module, its built-in signal processing unit completes the decoding, verification, and parsing, generating standardized drive commands and sending them to the drive control module. After receiving the commands, the drive control module precisely controls the start / stop, direction, and operating parameters of the motor 12 in the corresponding drive chamber. The motor 12 drives the worm gear 13 to rotate through the coupling. The worm gear 13 meshes with the worm wheel 11, causing the worm wheel 11 to rotate stably along the limit block. Since the threaded hole of the worm wheel 11 is threadedly connected to the lifting screw 14, and the lifting screw 14 passes through the lifting hole, the rotation of the worm wheel 11 drives the lifting screw 14 to perform linear lifting and lowering motion, thereby actuating the toggle of the miniature circuit breaker body 1 to achieve circuit on / off control.

[0038] During the status feedback process, the position sensor integrated in the status feedback module collects the displacement status of the lifting screw 14 and the on / off status of the miniature circuit breaker body 1 in real time. The status monitoring unit collects the operating parameters of the motor 12 and the power status of the battery 6 simultaneously. All collected status data are transmitted to the instruction parsing module for processing and then transmitted back to the remote control terminal via the remote signal receiving module, realizing real-time monitoring of the equipment's operating status.

[0039] When multiple miniature circuit breakers work together, the distributed communication and coordination module integrated in the Internet of Things communication platform establishes a data interaction link with other circuit breakers, and receives operation status data such as on / off status, load current, fault type, and fault occurrence time sent by other circuit breakers. If a fault status signal is received, the distributed communication and coordination module generates a linkage control strategy in combination with local operation status data, and synchronously adjusts the operation status of this device through the drive control module to achieve cluster-based safety control of the distribution circuit. At the same time, the communication link redundancy switching mechanism built in the distributed communication and coordination module continuously monitors the transmission quality of the primary and backup communication links. When the primary link experiences a transmission interruption or excessive error rate, it automatically switches to the backup link to maintain data interaction, and the switching process does not affect the execution of control instructions and the continuous transmission of status data.

[0040] In terms of power supply guarantee, the backup power supply management module continuously monitors the external power supply status. When the external power supply is abnormal, it immediately automatically switches to the battery 6 for power supply; after the external power supply is restored, it switches back to the external power supply and controls the charging of the battery 6. If the power of the battery 6 is lower than the preset threshold, the low power alarm unit will send an alarm signal to remind the staff to handle it in time to avoid the device losing connection due to power supply problems.

[0041] During the entire working process, the heat dissipation structures on the side walls of the upper drive chamber 3 and the lower drive chamber 4 continuously dissipate heat for the internal components. The overload protection unit of the drive control module can prevent the motor 12 from overloading. Each module efficiently exchanges data through the SPI communication bus, forming a closed-loop operation logic consisting of instruction reception - parsing - execution - status feedback, ensuring the stable, accurate, and safe operation of the device.

[0042] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
