[0039] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0040] Figure 1 It shows a schematic structural diagram of a system 100 of an intelligent circuit breaker according to an embodiment of the present invention;

[0041] like Figure 1As shown in , in the intelligent circuit breaker of the system 100, a wired port 102, a wireless port 103, a controller 104 and an execution unit 105 are included. The controller 104 communicates signals with the wired port 102, the wireless port 103 and the execution unit 104 respectively. The intelligent circuit breaker is wiredly connected to the peripheral device 101 through the wired port 102 to transmit Bluetooth pairing information between the intelligent circuit breaker and the peripheral device 101. The controller 104 connects the intelligent circuit breaker to the peripheral device 101 through the wireless port 103 according to the Bluetooth pairing information to transmit the circuit status signal. Further, the controller 104 controls the execution unit 105 to perform on-off operations based on the circuit status signal.

[0042] It should be noted that, based on the teachings of the context embodiments of the present invention, those skilled in the art can understand that other wireless connections can be made between the intelligent circuit breaker and the peripheral device through the wireless port, such as Star Flash technology, etc., but in the present invention, only Bluetooth is used as an example for illustration. Since the specific wireless connection form does not affect the control of the intelligent circuit breaker, they are all based on the intelligent circuit breaker and the method for controlling the intelligent circuit breaker shown in the present invention, so the present invention does not make too many restrictions in this regard.

[0043] Through the setting of the system 100 of the present invention, it is possible to establish a communication link between the intelligent circuit breaker and the peripheral device 101 using the wired port 102 or the wireless port 103 at different communication stages, so that the communication advantages of the wired link and the wireless link can be fully utilized. Specifically, for example, in the initial Bluetooth pairing stage, the intelligent circuit breaker can establish a wired link with the peripheral device 101 through the wired port 102. With the characteristics of safe and stable communication, high speed, and strong confidentiality of the wired link, both the intelligent circuit breaker and the peripheral device 101 can safely obtain each other's Bluetooth pairing information, effectively reducing the installation risks of wrong connection and virtual connection during wireless connection. After the Bluetooth pairing is successful, the intelligent circuit breaker and the peripheral device 101 establish a wireless link based on the Bluetooth protocol through the wireless port 103, so that the intelligent circuit breaker and the peripheral device are no longer limited to the workspace scene, and fast circuit signal transmission can be achieved.

[0044] In one embodiment, wireless transmission data can be encrypted to further improve data security and effectively prevent data from being tampered with, so that the circuit breaker action can be accurately and effectively controlled. Through the wireless port 103, the peripheral device 101 can effectively monitor the operating status of the intelligent circuit breaker in real time, achieve intelligent power management, and realize real-time remote control of the intelligent circuit breaker for on-off operations, thereby protecting the safety of the equipment and circuits.

[0045] Figure 2A schematic diagram of a process 200 of a Bluetooth pairing process according to an embodiment of the present invention is shown. Specifically, in the schematic diagram of the process 200, more details of the interaction between the smart circuit breaker in the system 100 and the peripheral device 101 through the wired port 102 are included, so the process 200 can be regarded as a possible embodiment of the system 100.

[0046] In the process 200, the intelligent circuit breaker is connected to the peripheral device 101 through the wired port 102, so that the Bluetooth pairing information is transmitted between the intelligent circuit breaker and the peripheral device 101, including: sending a query message to the peripheral device 101 through the wired port 102 to query whether the peripheral device 101 supports Bluetooth pairing. In response to the peripheral device 101 supporting Bluetooth pairing, receiving a first Bluetooth address reflecting the wireless address of the peripheral device 101 through the wired port 102; sending pairing connection information to the peripheral device 101 through the wired port 102, the pairing connection information carrying the second Bluetooth address and link key of the wireless port 102 in the intelligent circuit breaker, for Bluetooth pairing with the peripheral device 101.

[0047] Specifically, Figure 2 As shown, when the smart circuit breaker needs to perform Bluetooth pairing with the peripheral device 101, it is necessary to first query whether the peripheral device 101 supports Bluetooth pairing. Only after obtaining confirmation from the peripheral device 101 can the Bluetooth wireless connection with the other party (peripheral device 101) be performed by transmitting Bluetooth connection information. In one embodiment, the smart circuit breaker is connected to the peripheral device 101 through the wired port 102 to transmit Bluetooth pairing information between the smart circuit breaker and the peripheral device 101. The specific Bluetooth pairing process 200 includes the following steps:

[0048] In process S201 , a query message is sent to the peripheral device 101 through the wired port 102 to query whether the peripheral device 101 supports the wireless function of Bluetooth pairing.

[0049] At process S202, the smart circuit breaker receives the query response message returned by the peripheral device 101, and learns that the peripheral device 101 supports the Bluetooth pairing function and authorizes the pairing connection. Further, at process S203, the peripheral device 101 sends the first Bluetooth address reflecting its own wireless address to the smart circuit breaker through the wired link established with the smart circuit breaker.

[0050] Further, the process comes to S204, the intelligent circuit breaker receives the first Bluetooth address reflecting the wireless address of the peripheral device 101 through the wired port 102, and sends the pairing connection information to the peripheral device 101 through the wired port 102. In one embodiment, the pairing connection information carries the second Bluetooth address and link key of the wireless port 103 in the intelligent circuit breaker, which is used for Bluetooth pairing with the peripheral device 101 for wireless connection.

[0051] Further, at process S205, the smart circuit breaker and the peripheral device start Bluetooth pairing connection according to the Bluetooth address and link key of the other party in the Bluetooth pairing information. In one embodiment, the wireless port 103 of the smart circuit breaker includes a Bluetooth module, where the Bluetooth module is used for receiving and sending wireless data. When the Bluetooth pairing between the smart circuit breaker and the peripheral device is successful, the smart circuit breaker connects the smart circuit breaker and the peripheral device based on the Bluetooth protocol through the Bluetooth module configured in the wireless port 103, thereby realizing the wireless transmission of the circuit status signal between the smart circuit breaker and the peripheral device.

[0052] In one implementation scenario, in response to the pairing information indicating that the pairing is successful, the smart circuit breaker is connected to the peripheral device 101 through the wireless port 103 to transmit the circuit status signal.

[0053] In one embodiment, the intelligent circuit breaker and the peripheral device 101 connected via the wireless port 103 may include: receiving the circuit status signal of the peripheral device 101; and transmitting the circuit status feedback signal of the intelligent circuit breaker to the peripheral device 101 when transmitting the circuit status signal via the wireless port 103.

[0054] Through the process description of the above process 200, those skilled in the art can understand that by utilizing the security and stability of the wired link between the smart circuit breaker and the peripheral device, the connection information of the other party's wireless Bluetooth can be safely obtained, thereby ensuring that the wireless connection can be effectively established subsequently and ensuring the security of the Bluetooth pairing connection.

[0055] Figure 3a A schematic structural diagram of an intelligent circuit breaker including a circuit breaker module according to an embodiment of the present invention is shown.

[0056] like Figure 3a As shown, the intelligent circuit breaker further includes a circuit breaker module 106 ; the circuit breaker module 106 is connected to the controller 104 and the execution unit 105 , and is used to protect and isolate circuit faults, and send a monitored circuit state feedback signal to the controller 104 .

[0057] Figure 3b FIG. 3 is a schematic diagram showing a structure 300 of a circuit breaker module according to an embodiment of the present invention. Figure 3a and Figure 3b A detailed description of the circuit breaker module is given.

[0058] In the structure 300, the circuit breaker module 106 includes an electric parameter detection unit 1061, a short circuit protection unit 1062 and a conductive unit 1063. The electric parameter detection unit 1061 is connected to the conductive unit 1063 to detect changes in circuit parameters. The short circuit protection unit 1062 is connected to the conductive unit 1063 for short circuit current protection. The conductive unit 1063 is connected to the controller 104 to monitor the circuit state feedback signal and send the circuit state feedback signal to the controller 104.

[0059] In one embodiment, the electrical parameter detection unit 1061 can transmit the detected circuit parameter change state to the conductive unit 1063. When a short circuit occurs in the circuit, the short circuit protection unit 1062 notifies the conductive unit 1063 to implement short circuit current protection. Figure 3a As shown, the circuit breaker module 106 is connected to the controller 104 and the execution unit 105 for protecting and isolating the circuit fault. The circuit breaker module 106 sends the monitored circuit state feedback signal to the controller 104 according to the change of the circuit state. In an embodiment scenario, the conductive unit 1063 enables the circuit breaker module 106 to perform signal interaction with the external controller 104, so as to send the monitored circuit state feedback signal to the controller 104.

[0060] Those skilled in the art can understand that the circuit breaker module shown in structure 300, as a part of the intelligent circuit breaker, can be arranged in different ways in specific positions and divided into different ways in specific functions. In specific implementation applications, as long as the module functions of the above embodiments can be achieved, they can be flexibly adjusted according to actual application needs, and the present invention does not make any limiting provisions in this regard.

[0061] The circuit breaker module shown in the above structure 300 can detect the current circuit status of the circuit breaker. When a circuit fails or short-circuits, the circuit breaker is used to provide a real-time detection feedback signal and send the detection feedback signal to the controller for processing, thereby realizing the protection and isolation of the circuit by the circuit breaker module, and effectively protecting the safety of peripheral electrical equipment.

[0062] Figure 4 400 is a schematic diagram of a controller according to an embodiment of the present invention. As can be understood by those skilled in the art through the following description, Figure 4 The control 400 shown may be combined with Figure 1 The system 100 shown and Figure 3a and Figure 3b The illustrated structure 300 is understood as a further explanation of the system 100 and the structure 300 .

[0063] As shown in control 400, in one embodiment scenario, the controller 104 includes a signal transceiver unit 1041 and an instruction unit 1042. The signal transceiver unit 1041 is used to receive the collected circuit signal and perform a predetermined process on the collected circuit signal. The instruction unit 1042 issues a control instruction according to the predetermined process, and the control instruction includes sending it to the execution unit 105 for on-off operation.

[0064] In one embodiment, the signal transceiver unit 1041 is used to receive the collected circuit signal and perform predetermined processing on the collected circuit signal including: the circuit status signal of the peripheral device 101 collected through the wireless port 103 and / or the circuit status feedback signal fed back by the circuit breaker module 106; and the circuit status feedback signal is sent to the peripheral device 101 by controlling the wireless port 103 through the instruction unit 1042.

[0065] In one embodiment, the controller 104 also has metering and electrical parameter measurement functions, and can perform load analysis and control on users. Among them, the signal transceiver unit 1041 is used to receive the collected circuit signal and perform predetermined processing on the collected circuit signal. It should be noted that the circuit signal collected here can include several types. As an example, one type of circuit signal can be a circuit status signal of the peripheral device 101 collected through the wireless port 103, and another type of circuit signal can also be a circuit status feedback signal fed back by the circuit breaker module 106.

[0066] In one embodiment, the circuit state feedback signal fed back by the circuit breaker module 106 includes: an electrical parameter signal and / or a short circuit fault signal. The electrical parameter signal includes a circuit parameter change signal detected by the electrical parameter detection unit 1061 , and the short circuit fault signal includes a short circuit fault signal detected by the short circuit protection unit 1062 .

[0067] Further, the signal transceiver unit 1041 performs predetermined processing on the collected circuit signal, including: analyzing the type of the signal, analyzing the state of the circuit, and notifying the instruction unit 1042 to issue a corresponding control instruction. In one embodiment scenario, when the signal transceiver unit 1041 receives the overdue fee signal sent by the peripheral device 101, it notifies the instruction unit 1042 to issue a control instruction for the opening operation, and further sends the control instruction to the execution unit 105 to perform the opening operation. In another embodiment scenario, the signal transceiver unit 1041 receives the circuit opening state feedback signal sent by the circuit breaker module 106, and the instruction unit 1042 sends the control instruction to the wireless terminal 103, and sends the opening state feedback signal to the peripheral device 101 by controlling the wireless port 103. As described above, the circuit state feedback signal fed back by the circuit breaker module may include an electrical parameter signal and / or a short circuit fault signal in different embodiments. As shown in the combined structure 300, the electrical parameter detection unit 1061 is connected to the conductive unit 1063, and can detect the parameter change state of the current connected circuit. The controller 104 collects the electrical parameters of the electrical parameter detection unit 1061 and converts them into electrical parameter signals, and then controls the execution unit 105 to perform the on-off operation of the circuit according to the preset threshold. After the on-off operation is completed, the controller 104 feeds back the state of the on-off operation to the peripheral device 101 through the wireless port 103 to feed back the power consumption of the current circuit. It can be understood by those skilled in the art that the on-off operation here can be understood as a closing or opening operation. As an example, the above-mentioned electrical parameter signal can be an electrical parameter signal converted from a voltage signal, or it can be an electrical parameter signal converted from a current signal.

[0068] In one embodiment, when an overvoltage or undervoltage fault occurs in the current circuit, the controller 104 receives an electrical signal from the electrical parameter detection unit 1061 and controls the execution unit 105 to perform the opening operation of the circuit breaker. When the voltage returns to a normal value, the controller 104 controls the execution unit 105 to perform the closing operation of the circuit breaker. The conductive unit 1063 can detect the circuit change state of the above-mentioned opening operation or closing operation by being configured with a state detection device, thereby sending a feedback signal to the controller 104, and the controller 104 feeds back the state signal of the closing and opening operation to the peripheral device 101.

[0069] Further, in combination with the system 300, the short circuit protection unit 1062 is connected to the conductive unit 1063. When the short circuit protection unit 1062 detects a short circuit fault signal, the short circuit protection unit 1062 may be configured with a position sensor in one embodiment, and the position sensor detects the short circuit fault signal and sends it to the controller 104 through the conductive unit 1063, and the controller 104 sends the short circuit fault feedback signal to the peripheral device 101 through the wireless port 103.

[0070] Through the processing of the signal by the above-mentioned controller, the control execution unit 105 performs the on-off operation on the circuit breaker, and the circuit status signal of the peripheral device 101 can be processed in time. Functions such as power off, alarm, interlocking, etc. are executed to ensure the power safety of the peripheral device 101. At the same time, the real-time status of the circuit can be detected in time through the circuit breaker module 105, and feedback is given to the peripheral device 101 through the wireless port 103, ensuring the power safety of the user. Therefore, through the controller 104, the intelligent circuit breaker can interact with the peripheral device 101 in real time for the circuit status information, so as to provide more comprehensive line protection functions, such as overload, short circuit, overvoltage, undervoltage and other fault protection. At the same time, the circuit fault type can also be detected and fed back to the peripheral device.

[0071] Figure 5 FIG. 5 is a flow chart of a method 500 for controlling an intelligent circuit breaker according to an embodiment of the present invention. It should be understood that the method 500 is the aforementioned Figure 1 - Figure 4 A specific function implementation method, so the previous article combines Figure 1 - Figure 4 The features described apply analogously here as well.

[0072] The following will combine Figure 1 -4, the method 500 is specifically described. In the method 500, the method for controlling the intelligent circuit breaker includes: connecting the peripheral device 101 by using the wired port 103 to transmit the Bluetooth pairing information between the intelligent circuit breaker and the peripheral device 101. Based on the obtained Bluetooth pairing information, the intelligent circuit breaker is connected to the peripheral device 101 through the wireless port 103 to realize the transmission of the circuit state signal. Based on the received circuit state signal, the intelligent circuit breaker controls the execution unit 105 through the controller 104 to perform the on-off operation.

[0073] like Figure 5 As shown, the method 500 can be used to control the intelligent circuit breaker to perform a predetermined operation. Specifically, at process S501, the peripheral device is connected using a wired port to transmit Bluetooth pairing information between the intelligent circuit breaker and the peripheral device. Under normal circumstances, before the intelligent circuit breaker and the peripheral device are wirelessly connected, such as wirelessly connected based on the Bluetooth protocol, the pairing connection information of the two parties must first be exchanged, and then the wireless link can be connected according to the pairing connection information of the two parties. Here, the pairing information of the two parties may include the Bluetooth addresses and keys of the two parties.

[0074] In one embodiment of the present invention, in order to improve the efficiency of Bluetooth wireless pairing and ensure the security of pairing connection information, the pairing connection information of both parties can be communicated through a wired link. That is, by configuring a wired port on the smart circuit breaker, the smart circuit breaker and the peripheral device can be connected through a wired link, so that the pairing connection information of both parties can be communicated under the wired link, eliminating the risk of Bluetooth information leakage.

[0075] Specifically, the detailed process of the intelligent circuit breaker and the peripheral device communicating pairing connection information may include that the intelligent circuit breaker first uses the wired port to send query information to the peripheral device to query whether the peripheral device supports Bluetooth pairing. If the peripheral device gives feedback information that it supports Bluetooth pairing, the intelligent circuit breaker responds to the peripheral device supporting Bluetooth pairing and receives a first Bluetooth address reflecting the wireless address of the peripheral device. Then the intelligent circuit breaker sends its own pairing connection information to the peripheral device. The pairing connection information may carry, for example, a second Bluetooth address and a link key of the wireless port for Bluetooth pairing with the peripheral device. Through such interaction of pairing connection information, the wireless connection information of the paired parties can be obtained, so as to establish a wireless link connecting the two parties through the wireless address of the other party. Further, in response to the successful Bluetooth pairing of the peripheral device, the intelligent circuit breaker connects the intelligent circuit breaker to the peripheral device through the wireless port to realize the transmission of the circuit status signal.

[0076] Through the pairing connection method described above, the advantages of the wired link can be fully utilized. For example, in the process of exchanging pairing connection information, data transmission speed can be faster, anti-interference ability is stronger, stability is higher, and the transmitted Bluetooth pairing information also has a certain confidentiality.

[0077] Further, after the pairing information is exchanged based on the wired link in the above S501, the process goes to S502, and based on the obtained Bluetooth pairing information, the smart circuit breaker is connected to the peripheral device through the wireless port to realize the transmission of the circuit status signal. In one embodiment, in response to the successful Bluetooth pairing of the peripheral device, the smart circuit breaker is connected to the peripheral device through the wireless port to realize the transmission of the circuit status signal. Specifically, based on the Bluetooth address and link key of the smart circuit breaker, the peripheral device establishes a wireless connection based on the Bluetooth protocol with the smart circuit breaker through the wireless port of the smart circuit breaker. After the wireless connection is successful, the smart circuit breaker can realize the transmission of wireless signals with the peripheral device.

[0078] Furthermore, based on the obtained Bluetooth pairing information, the intelligent circuit breaker is connected to the peripheral device through the wireless port to realize the transmission of the circuit status signal, including: receiving the circuit status signal of the peripheral device; and transmitting the circuit status feedback signal of the intelligent circuit breaker to the peripheral device. Specifically, the intelligent circuit breaker can be configured with a circuit breaker module; transmitting the circuit status feedback signal of the intelligent circuit breaker to the peripheral device includes: the controller receives the internal circuit status feedback signal. Among them, the internal circuit status feedback signal is detected by the circuit breaker module, including electrical parameter signals and / or short circuit fault signals. Based on the internal circuit status feedback signal, the controller sends it to the peripheral device through the wireless port.

[0079] Further, the process comes to S503, based on the received circuit state signal, the intelligent circuit breaker controls the execution unit through the controller to perform the on-off operation. Specifically, the circuit state signal received here may include: receiving the circuit state signal of the peripheral device, and receiving the circuit state feedback signal of the intelligent circuit breaker. In one embodiment, the intelligent circuit breaker sends a control instruction to the execution unit through the controller based on the received circuit state signal of the peripheral device. Based on the control instruction, the execution unit performs the on-off operation according to the predetermined setting.

[0080] Here, the execution unit performs the on-off operation according to the predetermined setting, which is explained below through an embodiment. In one embodiment, the peripheral device is an electric meter. Through the detection of the electric meter, the user is currently in arrears. At this time, the electric meter will send a circuit status signal of arrears to the smart circuit breaker through a wireless link established based on the Bluetooth protocol. After the controller of the smart circuit breaker receives the circuit status signal of arrears, it sends a control instruction of opening the circuit to the execution unit, thereby disconnecting the user from continuing to use electricity resources. When the user completes the payment, the electric meter will send a paid circuit status signal. According to the paid circuit status signal, the smart circuit breaker sends a closing control instruction to the execution unit through the controller, so that it can continue to provide electricity to the user.

[0081] As an embodiment, the controller can also transmit the circuit status feedback signal of the intelligent circuit breaker to the peripheral device. Figure 3a As shown in FIG. 1 , the intelligent circuit breaker may further include a circuit breaker module. Here, the internal circuit state feedback signal is detected by the circuit breaker module, and may specifically include an electrical parameter signal and / or a short circuit fault signal. In one embodiment, based on the internal circuit state feedback signal, the controller sends it to the peripheral device via a wireless port. The generation method of the internal circuit state feedback signal may be combined with Figure 3a and Figure 3b The detailed description of the circuit breaker module 106 is omitted here.

[0082] In summary, the present invention uses the method for controlling the intelligent circuit breaker described above, and in the process of establishing communication between the intelligent circuit breaker and the peripheral device, combines the respective advantages of the wired link and the wireless link, and finally realizes remote and effective control of the intelligent circuit breaker. Specifically, on the one hand, the wired link is used for fast and accurate Bluetooth pairing connection, and the advantages of the wired link's fast transmission speed and stable data security are fully and effectively utilized, so that the Bluetooth pairing information can be transmitted faster and more stable between devices. Strong anti-interference. Since the information of Bluetooth pairing needs to be kept confidential to prevent leakage, a stronger confidentiality is also provided through the wired link. Further, based on the advantage that the wireless link can adapt to a wider range of communication environments, after the Bluetooth pairing is established through the wired link, the circuit signal interaction between the intelligent circuit breaker and the peripheral device is carried out through the connected wireless link. This method can take advantage of the wireless link, so that the signal transmission based on the Bluetooth protocol is convenient and fast, and there is also a certain security protection for the data. Therefore, the method for controlling the intelligent circuit breaker of the present invention can achieve a rapid response to the circuit state through remote control, thereby ensuring the safe use of power equipment.

[0083] The embodiment of the present invention also provides a device for controlling a device based on the Bluetooth protocol. Figure 6 The exemplary structural diagram of the control device 600 according to an embodiment of the present invention is schematically shown, which specifically comprises: a processor 601; and a memory 602, on which program instructions for controlling the intelligent circuit breaker are stored, and when the program instructions are executed by the processor 601, the method described in any one of the embodiments described above in the method 500 is implemented.

[0084] Specifically, the device 600 includes a processor 601 and a memory 602. According to different application scenarios, the processor 601 can be various types of chips, such as a central processing unit (CPU), other general-purpose microprocessors, or any conventional processors. In addition, these processors can be selected and configured as needed. For example, if high-speed computing and complex image processing are required, a high-performance GPU or other specialized processor can be selected.

[0085] The device 600 may further include a memory 602 storing computer instructions for controlling the intelligent circuit breaker. When the computer instructions are executed by the processor 601, the control device 600 executes the methods described in the above embodiments or implementations.

[0086] Based on the above, the present invention further discloses a computer-readable storage medium, which contains program instructions for controlling an intelligent circuit breaker based on a Bluetooth protocol. When the program instructions are executed by a processor, the method described in the above multiple embodiments or implementation methods is implemented.

[0087] In some implementation scenarios, the computer-readable storage medium may be any suitable magnetic storage medium or magneto-optical storage medium. Any such computer storage medium may be part of a device or apparatus, or may be accessible or connectable to a device or apparatus. Any application or module described in the present invention may be implemented using computer-readable / executable instructions that may be stored or otherwise maintained by such a computer-readable medium.

[0088] In order to help those skilled in the art to more clearly understand the control process of the intelligent circuit breaker of the present invention, Figure 7a The schematic diagram of the internal structure of the intelligent circuit breaker shown in the embodiment of FIG. 7c further systematically explains the system 100 and method 500 for controlling the intelligent circuit breaker described above.

[0089] like Figure 7a As shown, in one embodiment, the circuit breaker module of the intelligent circuit breaker may include a manganese copper piece, which is equivalent to the electrical parameter detection unit 1061 in FIG. 3 and is connected to the conductive unit 1063 (including the static contact 10631 and the moving contact 10632). The circuit breaker module is also configured with an electromagnetic coil 1063. Here, the electromagnetic coil unit realizes the function of the short-circuit protection unit 1062 in FIG. 3. The electromagnetic coil 1063 is connected to the conductive unit 1063 to realize short-circuit current protection. The electromagnetic coil 1063 may be configured to include a coil 10621 and a moving iron core 10622, and may also be configured with a position sensor and electrical signal feedback. The position sensor can detect the position state of the moving iron core 10622. When a short-circuit fault occurs in the circuit, the moving iron core 10622 generates an action and triggers the moving contact and the static contact in the conductive unit to disconnect the contact. The position sensor detects the position change and sends the short-circuit fault sensing signal to the controller. After processing, the controller sends a short-circuit fault signal to the peripheral device through the wireless port. In another embodiment, the conductive system is configured with electrical signal feedback, and when the moving and static contacts are turned on or off, the circuit state signal is transmitted to the controller. The controller detects the voltage signal of the manganese copper part 1061 according to the circuit state signal and converts it into an electrical parameter signal, and controls the execution unit to perform the on-off operation of closing or opening the switch according to the preset threshold.

[0090] like Figure 7b As shown, the controller 104 is configured with a control circuit board 1041 and a control chip 1042 in one embodiment. Through the control circuit board 1041, the controller can receive and process the collected signals and other functional logics, and control the execution unit to perform preset operations through the control chip 1042. The collected signals here may include circuit status signals sent by peripheral devices through wireless ports. The controller analyzes the received circuit status signals and controls the execution unit to perform on-off operations according to the preset configuration, and processes the internal feedback signals and sends them to the peripheral devices through the wireless port.

[0091] exist Figure 7b In one embodiment, the execution unit 105 may include a motor 1051, a gear 1052, and a driving member 1053. Figure 7c As shown, a tripping rod 1054 is also provided. When the controller issues a control instruction to the execution unit, the control motor 1051 drives the gear 1052 to start rotating, so that the movement of the driving member 1053 and the tripping rod 1054 can realize the on-off operation of closing and opening the circuit breaker.

[0092] It should be further explained that, in one embodiment of the intelligent circuit breaker, the wireless port is configured with a Bluetooth module. The Bluetooth module has the function of transmitting and receiving wireless data. In the intelligent circuit breaker, the Bluetooth module receives a signal and sends it to the controller, which processes the signal and controls the execution unit to perform a preset operation. Correspondingly, the Bluetooth module also receives a signal sent by the controller and transmits it to the peripheral device. Specifically, when the circuit breaker performs a closing or opening operation, the conductive unit of the circuit breaker feeds back a status signal to the controller, which is processed by the controller and sent to the peripheral device through the wireless port. For example, when an overvoltage or undervoltage fault occurs in the circuit, the controller collects the electrical signal of the conductive unit and controls the execution unit to perform the opening operation. When the voltage returns to normal, the controller controls the execution unit to close the circuit breaker. At the same time, the controller can also collect the voltage signal of the manganese copper part, convert it into electrical parameter data after processing, and send the circuit power feedback status to the peripheral device through the wireless port.
