TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical monitoring, in particular to an information monitoring module and a monitoring system. BACKGROUND

[0002] In electrical equipment such as power distribution cabinets and distribution boxes, the electrical energy data monitoring of the circuit breaker loop is an important link to ensure the stable operation of the power system. In the prior art, such monitoring is mostly achieved by cooperating a watt-hour meter with an external transformer, and there are many limitations in the structure and function: the line board of the existing monitoring device is mostly a single board, which cannot effectively utilize the space, resulting in a large overall size of the device, affecting the compactness of the internal layout of the cabinet; at the same time, in the existing scheme, the current signal acquisition relies on an external transformer, and the voltage signal acquisition needs additional wiring connection, which not only leads to a large number of connections and complex installation, but also requires regular calibration of the watt-hour meter and the transformer to ensure accuracy, increasing the maintenance cost; in addition, the communication between the existing monitoring device and the superior device adopts wired connection (such as 485 line), and when monitoring multiple loops, multiple communication lines need to be set up, further exacerbating the problems of messy wiring and large space occupation.

[0003] Therefore, there is an urgent need for an information monitoring module with reasonable structure layout, high integration, simplified wiring and strong adaptability to solve the problems of large space occupation, complex wiring and inconvenient maintenance in the prior art. SUMMARY

[0007] As an implementable manner, the mutual inductor is a high-precision mutual inductor of 5 parts per ten thousand level.

[0008] As an implementable manner, the mutual inductor is provided with a through hole, and the board surfaces of the first circuit board and the second circuit board are perpendicular to the axis of the through hole.

[0009] As an implementable manner, the inner wall of the shell is provided with a connecting column, the first circuit board and the second circuit board are both provided with through holes, the two through holes are coaxially arranged with the through hole, and the connecting column is sequentially arranged in one of the through holes, the through hole and the other through hole.

[0010] As an implementable manner, the mutual inductor comprises a magnetic core with the through hole and a secondary winding arranged on the magnetic core, and the orthogonal projection shape of the magnetic core on the first circuit board is circular or elliptical; when the orthogonal projection shape of the magnetic core on the first circuit board is elliptical, the secondary winding is wound around the two ends of the magnetic core along the major axis direction.

[0011] As an implementable manner, the shell is provided with a connecting hole, the conductive part is sequentially arranged in the connecting hole and the wiring hole of the circuit breaker to be electrically connected with the loop, and the power module is used to convert the high-voltage power source introduced by the conductive part into a low-voltage power source to power the metering module and the wireless communication module through the low-voltage power source.

[0012] In one possible implementation, the outer wall of the housing is in close contact with the outer wall of the circuit breaker, and the circuit breaker is provided with mounting holes. Fasteners are assembled into the mounting holes and abut against the conductive components, so that the housing and the circuit breaker are fixedly connected.

[0028] Please refer to the reference. Figures 1 to 4 This application provides an information monitoring module 100, including a housing 60 and a first circuit board 20, a second circuit board 30, a power module 70, a metering module 01, and a wireless communication module 80 disposed within the housing 60. The first circuit board 20 and the second circuit board 30 are arranged in parallel and spaced apart, and are electrically connected. The power module 70, the metering module 01, and the wireless communication module 80 are disposed on the first circuit board 20 or the second circuit board 30. The power module 70 is used to supply power to the metering module 01 and the wireless communication module 80. The metering module 01 includes a current transformer 10, a conductive element 40, and a metering chip. The current transformer 10 is located between the first circuit board 20 and the second circuit board 30. The current transformer 10 is used to collect the current signal of the circuit, the conductive element 40 is used to collect the voltage signal of the circuit, and the metering chip is used to calculate the electrical energy signal based on the current signal and the voltage signal, and transmit the electrical energy signal to an external device 300 through the wireless communication module 80. The information monitoring module 100 is installed in the form of an accessory backpack. It can monitor the power data of the circuit breaker circuit and transmit the power data to the external device 300 via wireless communication. It has the advantages of reasonable layout, high integration and simple wiring.

[0029] It should be noted that the information monitoring module 100 includes a housing 60, a first circuit board 20, a second circuit board 30, a power supply module 70, a metering module 01, and a wireless communication module 80. The housing 60 serves as a protective outer shell and may include a base 61 and a top cover 62 that interlock, with the interior housing other components. The first circuit board 20 and the second circuit board 30 are arranged parallel and spaced apart, and are electrically connected via wires, terminals, or pin headers, forming a layered circuit carrier. The power supply module 70, the metering module 01, and the wireless communication module 80 are respectively installed on the first circuit board 20 or the second circuit board according to actual needs. On the 30, for example, larger modules can be set on a separate circuit board, while smaller modules can be concentrated on another circuit board to make full use of the layered space; the metering module 01 includes a current transformer 10, a conductive element 40, and a metering chip. The current transformer 10 is located in the gap between the first circuit board 20 and the second circuit board 30 and is electrically connected to the first circuit board 20 or the second circuit board 30. The conductive element 40 (such as a conductive copper busbar or a metal spring) can be located at the input interface of its circuit board. The metering chip can be directly soldered to its circuit board, and the metering chip, the current transformer 10, and the conductive element 40 together form a signal transmission path.

[0030] The neutral wire can be connected in two ways: First, according to the location of the first circuit board 20 or the second circuit board 30 and the external circuit interface, cut a neutral wire of appropriate length. Then, using a soldering process, solder one end of the wire to the neutral pad on the first circuit board 20 or the second circuit board 30, and then connect the other end of the wire to the neutral interface of the external circuit. This method has the advantages of low contact resistance, stable current transmission, low risk of poor contact, and high electrical reliability. Second, pre-set a terminal block at the neutral interface of the first circuit board 20 or the second circuit board 30. During installation, insert the neutral wire of the external circuit into the socket of the terminal block and fix it in place. This method has the advantages of simple and convenient wiring operation, and allows for quick plugging and unplugging during later maintenance, resulting in high maintenance efficiency.

[0031] In operation, the information monitoring module 100 provided in this application provides stable power to the metering module 01 and the wireless communication module 80 through the power supply module 70; it also senses the current signal of the circuit breaker circuit through the current transformer 10 and collects the voltage signal of the circuit through the conductive component 40; it then receives the current signal and voltage signal through the metering chip and generates the corresponding power signal (such as power, power consumption, etc.) through calculation; and then sends the power signal to the external device 300 (such as a monitoring platform or mobile phone) through the wireless communication module 80 to realize remote data transmission.

[0032] The information monitoring module 100 provided in this application has a first circuit board 20 and a second circuit board 30 arranged parallel and spaced apart to form a double-layer structure. The current transformer 10 is then placed between the two circuit boards, which makes full use of the three-dimensional space within the housing 60. Compared with the single circuit board of existing monitoring devices, this layout can disperse component density and avoid poor heat dissipation or signal interference caused by component stacking. For example, the power module 70 (heat-generating component) and the wireless communication module 80 (sensitive component) can be set separately to improve circuit stability. All functional modules, including the power module 70, the metering module 01, and the wireless communication module 80, are integrated within the housing 60 to form a compact overall structure. This allows the information monitoring module 100 to be conveniently installed on the circuit breaker as an accessory backpack without occupying a large amount of space inside the cabinet. This highly integrated design reduces external wiring, making the modification of the circuit breaker circuit simpler, and is especially suitable for upgrading old power distribution systems.

[0033] The first circuit board 20 and the second circuit board 30 are electrically connected through a fixed interface, and the internal wiring is concentrated on the two circuit boards, making the wiring simpler. The metering module 01 collects current signals through the current transformer 10 and voltage signals through the conductive component 40. The division of labor is clear, reducing signal interference and ensuring the measurement accuracy of electrical energy data (such as power, electricity consumption, etc.). The wireless communication module 80 works independently and can transmit data to the external device 300 in real time to realize remote monitoring, avoid the errors of manual meter reading, and facilitate the timely detection of circuit abnormalities (such as overload, leakage), thus improving electrical safety. In later maintenance, the layered structure also facilitates the quick location of faulty components (such as checking a module on a specific circuit board), reducing maintenance costs.

[0034] As one possible implementation method, the current transformer 10 is a high-precision current transformer with a precision of 0.05%.

[0035] It should be noted that the high-precision current transformer 10 is located between the first circuit board 20 and the second circuit board 30, and is electrically connected to the metering chip. It is used to collect the current signal of the circuit breaker circuit. Its core function is to proportionally convert the high-voltage, high-current circuit signal into a low-voltage, low-current measurable signal, maintaining extremely low error (no more than ±0.005%) during the conversion process, providing the metering chip with accurate raw current data. The high-precision current transformer 10, with a precision of 0.05%, provides a precise and stable current signal. Combined with the voltage signal collected by the conductive element 40, the metering chip can calculate more accurate energy signals (such as power, electricity consumption, etc.), significantly improving the metering performance, environmental adaptability, and application range of the information monitoring module 100, better meeting the needs of high-end monitoring scenarios.

[0036] As one possible implementation method, such as Figure 1 and Figure 3As shown, the current transformer 10 is provided with a through hole 11, and the surfaces of the first circuit board 20 and the second circuit board 30 are both perpendicular to the axis of the through hole 11.

[0037] It should be noted that the current transformer 10 is provided with a through hole 11, and the surfaces of the first circuit board 20 and the second circuit board 30 (i.e., the planes of the circuit boards mainly used to carry electronic components) are both perpendicular to the axis of the through hole 11. Since the first circuit board 20 and the second circuit board 30 are parallel and spaced apart, they are located on both sides of the current transformer 10 and are both perpendicular to the axis of the through hole 11, forming a three-dimensional stacked structure of "first circuit board 20 - current transformer 10 - second circuit board 30". The axis of the through hole 11 passes perpendicularly through the space between the two circuit boards. This design makes full use of the vertical space inside the housing 60, making the overall structure of the information monitoring module 100 more compact, meeting the miniaturization requirements of accessory backpack installation, and adapting to circuit breakers of different sizes.

[0038] As one possible implementation method, such as Figure 1 As shown, a connecting post 63 is provided on the inner wall of the housing 60. Both the first circuit board 20 and the second circuit board 30 have through holes 21, which are coaxially arranged with the through hole 11. The connecting post 63 passes through one through hole 21, the through hole 11, and the other through hole 21 in sequence. It should be understood that the diameters of the two through holes 21 and the through hole 11 are greater than or equal to the outer diameter of the connecting post 63.

[0039] It should be noted that a connecting post 63 is provided on the inner wall of the housing 60, and through holes 21 are respectively provided on the first circuit board 20 and the second circuit board 30. The two through holes 21 are coaxially arranged with the through hole 11 on the current transformer 10 (or the axis coincides). The connecting post 63 passes through the through hole 21 of the first circuit board 20, the through hole 11 of the current transformer 10 and the through hole 21 of the second circuit board 30 in sequence (or passes through the through hole 21 of the second circuit board 30, the through hole 11 of the current transformer 10 and the through hole 21 of the first circuit board 20 in sequence), connecting the three components together to form an axially fixed structure of "first circuit board 20-current transformer 10-second circuit board 30". After the connecting post 63 is installed, it does not affect the parallel spacing between the first circuit board 20 and the second circuit board 30, nor does it interfere with the electrical connection (such as the connection of pins and wires) between the current transformer 10 and one of the circuit boards. At the same time, since the surface of the circuit board is perpendicular to the axis of the through hole 11, and since the through hole 21 is coaxial with the through hole 11, the axis of the connecting post 63 can remain perpendicular to the surface of the circuit board, ensuring that the fixing direction of the connecting post 63 for each component is consistent with the overall layout.

[0040] The connecting post 63 rigidly connects the first circuit board 20, the current transformer 10, and the second circuit board 30 through the coaxial through hole 21 and through hole 11. During assembly, the initial positioning can be completed simply by aligning the holes of each component and inserting them into the connecting post 63, reducing calibration steps during assembly and improving production efficiency. It can also effectively limit the relative displacement of the three components in the direction of the circuit board surface, avoiding component displacement caused by vibration and impact, especially preventing the electrical connection point between the current transformer 10 and the circuit board from loosening, ensuring the stability of the overall component structure. At the same time, it can accurately position the relative positions of the first circuit board 20, the current transformer 10, and the second circuit board 30, ensuring that the through hole 11 of the current transformer 10 is always perpendicular to the surface of the circuit board, avoiding the impact of assembly deviation on the signal detection accuracy of the current transformer 10.

[0041] As one possible implementation method, such as Figure 3 As shown, the current transformer 10 includes a magnetic core 13 (such as a microcrystalline magnetic core 13) with a through hole 11 and a secondary winding 12 disposed on the magnetic core 13. The orthographic projection shape of the magnetic core 13 on the first circuit board 20 is circular or elliptical. When the orthographic projection shape of the magnetic core 13 on the first circuit board 20 is elliptical, the secondary winding 12 is wound around both ends of the magnetic core 13 along the long axis.

[0042] It should be noted that the orthographic projection of the current transformer 10 onto the first circuit board 20 (i.e., the outline formed by projection along a direction perpendicular to the surface of the first circuit board 20) is circular or elliptical. The circular or elliptical projection shape can adapt to the layout of components on the circuit board, avoiding space waste caused by irregular projection outlines. In particular, the elliptical projection allows for adjustment of the major axis direction according to the narrow space of the circuit board, rationally allocating the installation space of the current transformer 10 within a limited area, and reducing interference with the layout of other components on the circuit board.

[0043] When the orthographic projection is elliptical, the secondary windings 12 of the current transformer 10 can be symmetrically distributed at both ends of the current transformer 10 along its major axis. Here, the major axis refers to the direction of the major axis of the ellipse. The secondary windings 12 form a symmetrical layout at opposite ends of the major axis of the ellipse, with the minor axis as the axis of symmetry. This allows for an increase in the thickness of the magnetic core 13 within a limited space, resulting in a more balanced magnetic field or induction area generated by the secondary windings 12 along the major axis. This provides more comprehensive coverage of the area to be detected, reduces induction signal deviation caused by uneven distribution of the secondary windings 12, and improves the accuracy of the current transformer 10 in detecting parameters such as current and voltage.

[0044] As one possible implementation method, such as Figure 1 and Figure 2As shown, the housing 60 is provided with a connection hole 64, and the conductive element 40 is sequentially inserted into the connection hole 64 and the wiring hole of the circuit breaker to be electrically connected to the circuit. The power module 70 is used to convert the high voltage power introduced by the conductive element 40 into a low voltage power supply to power the metering module 01 and the wireless communication module 80.

[0045] It should be noted that the housing 60 is provided with a connection hole 64, the diameter of which is adapted to the size of the conductive component 40. One end of the conductive component 40 (such as a conductive copper busbar or metal spring) passes through the connection hole 64 of the housing 60 and the wiring hole of the circuit breaker in sequence, forming an electrical connection with the circuit inside the circuit breaker (such as a power line). The other end is connected to the first circuit board 20 or the second circuit board 30 inside the housing 60, transmitting the voltage signal of the circuit to the metering module 01. The power module 70 is electrically connected to the conductive component 40, receiving the high-voltage power (such as 220V AC or 380V industrial power) introduced by the conductive component 40. Through the internal transformer, rectifier, and voltage regulator circuit (such as an AC / DC converter), the high-voltage power is converted into low-voltage power (such as 5V or 3.3V), and the circuit of the circuit board provides stable operating power to the metering module 01 and the wireless communication module 80, reducing the risk of circuit burnout.

[0046] The conductive component 40 simultaneously performs the dual functions of voltage signal acquisition and high-voltage power supply introduction. It eliminates the need for a separate wiring structure for the power module 70; only the connection hole 64 and wiring hole need to be run once, simplifying the connection between the information monitoring module and the circuit breaker, reducing the number of external wires, and making installation more convenient, especially suitable for space-constrained distribution cabinet scenarios. By directly drawing power from the circuit breaker circuit through the conductive component 40, no additional external power supply (such as a battery or dedicated power line) is required, making the information monitoring module 100 an independent self-powered device. This avoids the maintenance costs of battery replacement or the wiring limitations of external power lines, allowing for flexible installation on various circuit breakers (such as household miniature circuit breakers and industrial large circuit breakers), thus enhancing its adaptability.

[0047] In one possible implementation, the outer wall of the housing 60 is in close contact with the outer wall of the circuit breaker. The circuit breaker is provided with mounting holes, and fasteners are assembled in the mounting holes and abut against the conductive element 40, so that the housing 60 is fixedly connected to the circuit breaker.

[0048] It should be noted that the outer wall of the housing 60 mentioned above refers to the outer wall of the housing 60 with the connection hole 64. When assembling the information monitoring module 100 and the circuit breaker, firstly, align the end of the conductive component 40 that protrudes from the housing 60 through the connection hole 64 with the wiring hole of the circuit breaker; then, continue to move the information monitoring module 100 toward the side closer to the circuit breaker until the outer wall of the housing 60 is in contact with the outer wall of the circuit breaker; subsequently, install the fasteners (such as screws) into the mounting holes of the circuit breaker until the ends of the fasteners abut against the conductive component 40, so that the housing 60 is fixedly connected to the circuit breaker, and at the same time, the conductive component 40 is electrically connected to the circuit inside the circuit breaker.

[0049] As one possible implementation method, such as Figure 1 As shown, a first snap-fit ​​part 65 is provided on the outer wall of the housing 60, and a second snap-fit ​​part is provided on the circuit breaker. The first snap-fit ​​part 65 and the second snap-fit ​​part cooperate to make the housing 60 snap-fit ​​with the circuit breaker.

[0050] It should be noted that the outer wall of the housing 60 is provided with a first snap-fit ​​part 65 (such as a protruding buckle, elastic claw, or groove), and the circuit breaker is provided with a corresponding second snap-fit ​​part (such as a slot, protrusion, or hole that matches the first snap-fit ​​part 65). The shapes and sizes of the two are matched, and they can be detachably fixed through mechanical engagement. During installation, the housing 60 is placed close to the preset installation position of the circuit breaker, and the first snap-fit ​​part 65 and the second snap-fit ​​part can be aligned. By applying a pushing force, the two are made to snap together (such as the buckle sliding into the slot and locking), thereby firmly connecting the housing 60 and the circuit breaker, further improving the stability of the connection between the housing 60 and the circuit breaker. During disassembly, the first snap-fit ​​part 65 and the second snap-fit ​​part are separated by pressing the elastic claw, which enables the quick assembly and disassembly of the information monitoring module 100.

[0051] Please refer to the reference again. Figure 5 This application embodiment also provides a monitoring system, including a gateway 200, multiple circuit breakers and multiple information monitoring modules 100 as described above. The multiple circuit breakers and multiple information monitoring modules 100 are configured in a one-to-one correspondence, and the multiple information monitoring modules 100 are connected to an external device 300 bus through the gateway 200.

[0052] It should be noted that the monitoring system includes a gateway 200, multiple circuit breakers, and multiple information monitoring modules 100. Each circuit breaker is configured with one information monitoring module 100 (i.e., a one-to-one correspondence). The information monitoring module 100 is installed on the corresponding circuit breaker in the form of an accessory backpack (e.g., fixed by the first snap-fit ​​part 65 cooperating with the second snap-fit ​​part of the circuit breaker), realizing the monitoring of the power data of a single circuit breaker circuit. All information monitoring modules 100 establish communication connections with the gateway 200 (e.g., interacting with the wireless receiving unit of the gateway 200 through the wireless communication module 80). The gateway 200 then aggregates the data from all information monitoring modules 100 and connects to external devices 300 (e.g., monitoring platform, server, terminal display) through a bus (e.g., Ethernet, RS485 bus, etc.), forming a hierarchical communication architecture of "circuit breaker - information monitoring module 100 - gateway 200 - external device 300".

[0053] Multiple information monitoring modules 100 are configured in a one-to-one correspondence with multiple circuit breakers, which can simultaneously collect data such as current, voltage, and energy of each circuit. After being aggregated by gateway 200, the data is transmitted to external device 300, allowing managers to view the power status of all circuits (such as load distribution and energy consumption statistics) on the same platform without having to check each individual circuit breaker. This is especially suitable for multi-circuit power distribution systems (such as office buildings and factory workshops), greatly improving the convenience and efficiency of power management.

[0054] The information monitoring module 100 connects to the external device 300 via a bus through the gateway 200, rather than communicating directly with the external device 300. This reduces the communication load on the external device 300 (e.g., avoiding the simultaneous handling of connection requests from multiple information monitoring modules 100). As an intermediate node, the gateway 200 optimizes data transmission paths (e.g., filtering key data and compressing redundant information), improving communication stability. Furthermore, if additional monitoring loops are needed, only the corresponding circuit breaker and information monitoring module 100 need to be added and connected to the gateway 200; no modification to the external device 300 is required, resulting in strong system scalability.

[0055] The massive amounts of data collected through centralized monitoring are transmitted to external devices 300 via gateway 200, where they can be processed in depth using data analysis tools (such as comparing energy consumption of each circuit and identifying abnormal power consumption patterns). For example, when the current in a certain circuit suddenly exceeds the standard, the system can quickly locate the corresponding circuit breaker and information monitoring module 100, trace the cause of the fault through historical data (such as equipment aging or overload), achieve fault early warning and accurate troubleshooting, and reduce power outage time.

[0056] The wireless communication module 80 of the information monitoring module 100 (such as Bluetooth, LoRa, or Wi-Fi) can flexibly adapt to the communication method of the gateway 200. The gateway 200 then connects to the external device 300 via a bus, balancing the convenience of short-range wireless communication (between the information monitoring module 100 and the gateway 200) and the reliability of long-range wired communication (between the gateway 200 and the external device 300). This hybrid communication architecture is suitable for scenarios of different sizes (such as using a wireless gateway 200 in a small office building and a wired bus in a large factory), improving the system's scenario adaptability.

[0057] As one possible implementation method, such as Figure 5 As shown, the wireless communication module 80 is a Bluetooth module, and the multiple information monitoring modules 100 are independent of each other. The multiple information monitoring modules 100 and the gateway 200 are connected to each other via Bluetooth modules.

[0058] It should be noted that the wireless communication modules 80 of each information monitoring module 100 are Bluetooth modules, supporting short-range wireless communication. The multiple information monitoring modules 100 operate independently, meaning they do not establish communication connections with each other and exist as independent devices. Furthermore, each information monitoring module 100 connects only to the Bluetooth receiving unit of the gateway 200, forming a star topology of "information monitoring module 100 - gateway 200". Therefore, the power data (such as current, voltage, and power signals) collected by a single information monitoring module 100 can be directly transmitted to the gateway 200 via its own Bluetooth module, and the status information (such as online status and fault indications) of each information monitoring module 100 is also transmitted only to the gateway 200. This star topology design facilitates deployment in large-scale environments and avoids information collisions between multiple information monitoring modules 100, improving the stability and efficiency of data transmission.

[0059] As one possible implementation method, such as Figure 5 As shown, the information monitoring module 100 is used to obtain the power signal of the metering module 01 according to the broadcast query command forwarded by the gateway 200, and forward the power signal to the external device 300 through the gateway 200. The information monitoring module 100 may be equipped with a storage unit for real-time storage of the power signal of the metering module 01 to ensure data continuity and integrity, and to record the power consumption status even when not being queried.

[0060] It should be noted that when a user needs to obtain data (such as by initiating a request through a host computer), the gateway 200 will actively send a broadcast query command (such as a wireless signal containing the query command) to multiple information monitoring modules 100. After receiving the broadcast information through the Bluetooth module, each information monitoring module 100 will trigger an internal response, retrieve the historical or real-time power signals (such as power and electricity consumption data calculated from current and voltage) required by the user from the storage unit, and then feed these power signals back to the gateway 200 through the Bluetooth module. The gateway 200 will then collect and forward them to the external device 300 (such as a monitoring platform or terminal display).

[0061] The broadcast query command contains a unified query command (such as obtaining current power data) to ensure that all information monitoring modules 100 respond synchronously; the power signals returned by the information monitoring module 100 have their own identifiers (such as the number of each information monitoring module 100), so that the gateway 200 can distinguish the monitoring data corresponding to different circuit breakers and avoid confusion.

[0062] By adopting a "gateway 200 broadcast query - information monitoring module 100 response" mode, the transmission of power signals is actively triggered by the gateway 200, rather than the information monitoring module 100 continuously sending data. This reduces wireless channel occupancy (e.g., avoiding signal conflicts caused by multiple information monitoring modules 100 transmitting simultaneously) and lowers communication redundancy. Especially in scenarios where multiple information monitoring modules 100 are cascaded, on-demand data collection optimizes Bluetooth communication bandwidth and improves data transmission efficiency and accuracy.

[0063] Gateway 200 can adjust the broadcast query frequency according to actual needs (e.g., high-frequency query during real-time monitoring, low-frequency query during routine monitoring), while information monitoring module 100 provides real-time feedback of the latest power signals, ensuring that the data acquired by external device 300 reflects the true state of the current circuit breaker circuit. This dynamic response mechanism is suitable for scenarios sensitive to power consumption (such as power supply circuits for precision equipment), facilitating the timely detection of problems such as sudden current changes and voltage anomalies.

[0064] The information monitoring module 100 does not need to maintain a continuous data transmission state. It only initiates the data retrieval and transmission process when it receives a broadcast query from the gateway 200. At other times, it can be in a low-power standby mode. This, combined with the low-power characteristics of the Bluetooth module, can further reduce the power consumption of the information monitoring module 100, extend the life of electronic components, and reduce the dependence on power from the circuit breaker circuit.

[0065] Furthermore, users can also operate their own devices (such as mobile phones or handheld terminals) locally (e.g., near the information monitoring module 100) without going through the gateway 200, establishing a Bluetooth connection with the information monitoring module 100 to directly obtain historical or real-time data (such as power consumption or instantaneous current over a specific time period) from the storage unit. This method is suitable for scenarios such as temporary queries and single-module debugging, offering greater operational flexibility and eliminating reliance on the gateway 200's forwarding function. Even if the gateway 200 experiences a temporary failure, users can still obtain data locally, ensuring that critical information is not lost and improving the reliability of the monitoring system.
