[0036] Since existing intelligent circuit breakers can only realize related functions such as power parameter monitoring, remote opening and closing, and power safety protection, the circuit breakers in the existing technology cannot dynamically adjust the load control tolerance according to the ever-changing power demand (and the load conditions of regional power supply and distribution equipment) to meet the power demand and balance the limited power supply and distribution capacity (resources). Through the technical solution of the embodiment of the present invention, active capacity expansion is achieved through the circuit breaker, and the load control tolerance or power load is adjusted according to the results of the response from the superior control center, thereby solving the problems of low power supply equipment utilization and power efficiency, overload tripping, etc.

[0037] In this embodiment, a method for dynamically adjusting the negative control tolerance of the circuit breaker is provided. Figure 2 FIG. 1 is a flow chart of a method for dynamically adjusting the negative control margin according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0038] Step S202: When the circuit breaker monitors that the power load of the electrical equipment exceeds the load control tolerance, or the difference between the load control tolerance and the power load is less than a preset threshold, the circuit breaker applies to the superior control center for capacity adjustment to increase the load control tolerance.

[0039] Step S204: receiving, through the circuit breaker, a request result replied by the upper control center within a preset time period, wherein, within the preset time period, the circuit breaker is prohibited from performing negative control tripping;

[0040] Step S206, when the request result indicates that the load control tolerance is allowed to be increased, instructing the circuit breaker to adjust the load control tolerance to the load control tolerance after the adjustment and increase, and perform load control according to the load control tolerance after the adjustment and increase;

[0041] Step S208, when the request result indicates that the negative control margin cannot be increased or when no response is received from the superior control center, instructing the circuit breaker to perform negative control tripping according to the negative control margin after the preset time period;

[0042] In the present invention, the load control margin may be understood as the capacity limit for power load control, that is, the maximum load limit for power load control (for example, a specified current, power value, etc.) set for power load control.

[0043] It can be understood that the power load in the above steps may be the power load (of the electrical equipment) carried by the circuit breaker; and the negative control tolerance in the above steps may be the negative control tolerance of the circuit breaker.

[0044] It can be understood that in step S206, when the circuit breaker adjusts the load control tolerance to the load control tolerance after the adjustment and capacity increase, the load control can be performed according to the load control tolerance after the adjustment and capacity increase, that is, the circuit breaker can execute step S202 according to the load control tolerance after the adjustment and capacity increase;

[0045] It is understood that in step S208, negative control tripping refers to tripping when the power load exceeds the negative control tolerance. That is, the circuit breaker performs negative control tripping according to the negative control tolerance, which means that the circuit breaker trips when the power load exceeds the negative control tolerance.

[0046] Through the present invention, a circuit breaker is introduced into the control process of regional electricity consumption, and the power load of the electrical equipment is monitored by the circuit breaker. When the power load of the above-mentioned electrical equipment exceeds the negative control tolerance, or the difference between the negative control tolerance and the power load is less than a preset threshold, the circuit breaker actively applies to the superior control center for adjustment and capacity increase to increase the negative control tolerance, and receives the request result of the superior control center within a preset time period, and performs subsequent operations according to the request result. The above-mentioned technical solution solves the problems of low power supply equipment utilization and power efficiency, which are easy to cause overload tripping, in the control method of regional electricity consumption in related technologies, thereby improving power efficiency and avoiding overload tripping.

[0047] It can be understood that in an embodiment of the present invention, when the circuit breaker detects that the electrical equipment has an extraordinary power demand (that is, the power consumption gateway where the circuit breaker is located needs to increase the power capacity, which can be specifically judged by determining the comparative relationship between the above-mentioned negative control tolerance and the power load), it can actively apply to the superior control center for adjustment and capacity increase, wherein the superior control center includes at least one of the following: a regional coordination control device, a cloud server, and the embodiment of the present invention does not limit this. Then, the circuit breaker increases the negative control tolerance (of the circuit breaker) or controls the electrical equipment to adjust the power load / trend power load to be controlled below the negative control tolerance based on the information judged and fed back by the regional coordination control device or the cloud server according to the load situation of the regional power supply and distribution equipment.

[0048] Through the above technical solution, the extraordinary electricity demand of specific users (which can be understood as the electrical equipment in the above embodiment) can be dynamically met, while ensuring the safety and reliability of electricity use in the region and users, improving the user's electricity experience, and improving the utilization rate of regional power supply equipment, low electricity efficiency, overload tripping caused by blind / disorderly capacity expansion, and other problems.

[0049] In order to increase the safety of the adjustment and capacity increase operation, before executing the above step S202, the following operations need to be performed: obtaining the allowable capacity upper limit corresponding to the circuit breaker; when the load control tolerance has been adjusted to the allowable capacity upper limit, or the power load exceeds the allowable capacity upper limit, instructing the circuit breaker to perform load control tripping according to the allowable capacity upper limit, and prohibiting the application for capacity adjustment to the superior control center through the circuit breaker, wherein the allowable capacity upper limit can be understood as the maximum load control tolerance allowed to be set for the circuit breaker, which can be the maximum capacity or rated capacity allowed for the power distribution equipment / power equipment on the line where the circuit breaker is located, or the rated capacity of the circuit breaker. When the power load exceeds the maximum load control tolerance or the load control tolerance has reached the maximum load control tolerance, the circuit breaker performs load control tripping according to the allowable capacity upper limit, and the circuit breaker is not allowed to apply for capacity adjustment to the superior control center again.

[0050] In an embodiment of the present invention, the setting of the preset time period needs to refer to other parameters, and the preset time period is determined by at least one of the following methods: the preset time period is inversely proportional to the negative control tolerance, wherein the larger the negative control tolerance is, the shorter the preset time period is; the smaller the negative control tolerance is, the longer the preset time period is; the preset time period is inversely proportional to the degree of over-limit of the power load, wherein the greater the degree of over-limit is, the shorter the preset time period is; and the smaller the degree of over-limit is, the longer the preset time period is.

[0051] It should be noted that the greater the degree of exceeding the limit (i.e., the more serious the degree of exceeding the limit) can be quantitatively understood in the following ways: the larger the peak value, the larger the mean value, the larger the effective value, the more frequent the occurrence, the longer the cumulative duration, etc. Any of the above situations can be understood as the more serious the degree of exceeding the limit. In addition, the inverse relationship between the preset time period and the negative control tolerance, and the inverse relationship between the preset time period and the degree of exceeding the limit can be achieved through any function that can characterize the inverse relationship, and the embodiments of the present invention are not limited to this.

[0052] Optionally, after the power load of the electrical equipment drops to the target amount and the time when the power load is at the target amount is maintained for the target time, the load control tolerance is reduced by the circuit breaker to perform load control according to the reduced load control tolerance. That is to say, if the power load of the electrical equipment has dropped to the target amount and has been maintained at the target amount for a period of time, it can actually be said that the electrical equipment currently has a part of the power capacity quota spared, or it can be understood that the power demand has decreased. Then, in order to improve the efficiency of the load control of the circuit breaker and improve the utilization rate of the power supply and distribution equipment, the load control tolerance of the circuit breaker can be reduced accordingly, and then load control can be performed according to the reduced load control tolerance. The circuit breaker can execute step S202 according to the reduced load control tolerance.

[0053] Optionally, when the power load of the electrical equipment drops to a target amount and it is known that the power load has been shut down or disabled, the load control tolerance may be reduced by the circuit breaker to perform load control according to the reduced load control tolerance.

[0054] It should be noted that there are multiple ways to implement the above-mentioned step S202. In an optional embodiment, it is determined that the circuit breaker receives a target request instruction; in response to the target request instruction, an application is made to the superior control center through the circuit breaker for capacity adjustment and increase to increase the load control margin. Specifically, determining that the circuit breaker receives the target request instruction includes at least one of the following: determining that the circuit breaker receives a target request instruction triggered by a button on the circuit breaker. In this implementation, before the button triggers the target request instruction, the amount of load capacity increase and the duration or time period of the load capacity increase can be set in advance, and the above-mentioned target request instruction is triggered according to the amount of load capacity increase and / or the duration or time period of the load capacity increase; determining that the circuit breaker obtains the target request instruction generated by the circuit breaker after recognizing the target voice; determining that the circuit breaker receives the target request instruction sent via a mobile terminal, for example, by operating the supporting software of the circuit breaker on a mobile phone / tablet to apply, or by scanning the circuit breaker QR code via a mobile phone / tablet to apply.

[0055] In addition to the above functions, the circuit breaker provided in the embodiment of the present invention can also realize the following functions:

[0056] 1) Passive capacity increase function: The circuit breaker receives a first control instruction sent by the superior control center; in response to the first control instruction, the negative control margin is adjusted to the negative control margin after the capacity increase. That is, the circuit breaker in the embodiment of the present invention passively adjusts the negative control margin after receiving the first control instruction from the superior control center.

[0057] 2) Passive derating function: receiving a second control instruction sent by the superior control center through the circuit breaker; responding to the second control instruction, derating the negative control tolerance through the circuit breaker.

[0058] That is, the circuit breaker receives the second control instruction sent by the upper-level control center to adjust the negative control tolerance.

[0059] In an embodiment of the present invention, when the first control instruction and / or the second control instruction carries at least one of the following parameter information: the capacity value adjusted by the negative control tolerance, the adjustment period, the adjustment resource (for example, the electricity capacity price), the circuit breaker is instructed to adjust the negative control tolerance according to the parameter information, and / or determine the resource value to be provided according to the adjustment resource (for example, the billing value corresponding to the electricity capacity price).

[0060] Specifically, the circuit breaker can adjust the negative control tolerance to the target amount according to the capacity value adjusted by the negative control tolerance, can maintain the adjusted negative control tolerance amount within the target time period according to the adjustment period, and can determine the resource value (total amount) to be provided based on the adjustment resources (the amount of each measurement unit).

[0061] 3) Capacity expansion and renewal function: After instructing the circuit breaker to adjust the load control tolerance to the load control tolerance after capacity expansion, the method further includes: when the adjustment period of the load control tolerance adjustment expires, instructing the circuit breaker to automatically apply to the superior control center for renewal based on the power load to maintain the load control tolerance after capacity expansion.

[0062] Specifically, the adjusted load control tolerance is only maintained within the adjustment period. After the adjustment period, the power load has not dropped to the target amount. In this case, in order to continue to maintain the load control tolerance after the adjustment and capacity increase, the circuit breaker will automatically apply to the superior control center for an extension of the period (increase the duration).

[0063] Optionally, before the negative control tolerance is derated by the circuit breaker, the electrical equipment is controlled to reduce the power load so that the reduced power load is less than the negative control tolerance after the derated adjustment. That is, in order to prevent the circuit breaker from tripping, the method adopted may be to reduce the power load of the electrical equipment to below the negative control tolerance after the proposed derated adjustment.

[0064] Optionally, a power demand response instruction is received through a circuit breaker; in response to the power demand response instruction, the power equipment is controlled to reduce the power load and / or the load control tolerance is derated according to the power load priority control strategy stored in the circuit breaker.

[0065] Optionally, when the request result indicates that the negative control tolerance is not allowed to be increased or when no reply is received from the superior control center, the power load of the electrical equipment is adjusted so that the adjusted power load is less than the negative control tolerance. That is, in order to prevent the circuit breaker from tripping, the method adopted may be to reduce the power load of the electrical equipment to below the negative control tolerance.

[0066] Optionally, a third control instruction sent by a target object is received through the circuit breaker, wherein the target object includes at least one of the following: a mobile client, a mobile applet, a superior circuit breaker, a smart meter, and a smart electricity monitoring terminal; in response to the third control instruction, at least one of the following operations is performed on the electrical equipment: switch control, closing and locking.

[0067] That is, the smart circuit breaker receives the APP / applet of the mobile terminal, or the control instructions of the superior household smart circuit breaker / smart meter / smart electricity monitoring terminal, and performs operations such as switching and locking of conventional electrical equipment.

[0068] Optionally, when the circuit breaker receives a third control instruction for indicating a closing lock, the circuit breaker is prohibited from performing a closing operation, and / or the tripping mechanism in the circuit breaker is controlled to be in a tripping state, so that the circuit breaker cannot be in a closing state or a closed position (i.e., it cannot be closed manually or remotely).

[0069] Optionally, when the circuit breaker receives a fourth control instruction for instructing to release the lock, the internal trip of the circuit breaker is controlled to reset so that the circuit breaker can be closed.

[0070] It can be seen that in the embodiment of the present invention, the circuit breaker can realize coordinated regulation of the switches and power consumption of the user's internal electrical equipment (including smart electrical equipment, smart circuit breakers that supply power to conventional electrical equipment, electrical equipment monitoring terminals, etc.) at the user's power consumption gateway according to the load control tolerance and dynamic adjustment process, so that the total load of the electrical equipment is not overloaded.

[0071] 4) Communication function: Establish a connection with the circuit breaker through the circuit breaker client or applet; based on the established connection, implement data interaction between the circuit breaker and the circuit breaker client or applet, or instruct the circuit breaker to interact with the upper control center based on the connection.

[0072] That is, in this communication function, the APP or applet of the mobile terminal can connect to the circuit breaker via Bluetooth, and then monitor the circuit breaker operation data information through the APP or applet to implement auxiliary capacity expansion, load reduction control, modification of capacity expansion / derating related parameter configuration and other processes; in addition, the circuit breaker can use the network of the mobile terminal to indirectly communicate with the regional coordination control device or cloud server, etc., to transmit data, send requests or receive instructions, thereby solving the problems of high cost, difficult construction and weak signal coverage when the circuit breaker directly uses wired communication or wireless networking.

[0073] In summary, circuit breakers can add dynamic load control adjustment functions through embedded software to realize active capacity increase application, active capacity reduction, auxiliary capacity increase, passive capacity increase, passive capacity reduction, etc. In addition, they can also cooperate with APP, regional coordination control devices or cloud servers to dynamically adjust their load control tolerance.

[0074] In other words, through the technical solutions described in the embodiments of the present invention, the monitoring terminal and circuit breaker are highly integrated (which can be understood as the fusion of primary and secondary equipment, forming an intelligent switch), simplifying the system, reducing size, and lowering costs. The smart meter / smart electricity monitoring terminal + home switch, along with the power supply switch and its locking mechanism + power supply monitoring terminal of the terminal electrical equipment, are all integrated into one, achieving an integrated solution.

[0075] Through the description of the above embodiments, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus the necessary general hardware platform, and of course it can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present invention is essentially or the part that contributes to the prior art can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for enabling a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods described in each embodiment of the present invention.

[0076] This embodiment also provides a dynamic adjustment device for negative control tolerance, which is used to implement the above-mentioned embodiments and preferred embodiments. Details already described will not be repeated here. As used below, the term "module" may refer to a combination of software and / or hardware that implements a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementation using hardware, or a combination of software and hardware, is also possible and contemplated.

[0079] A receiving module 32 is configured to receive a request result replied by the superior control center within a preset time period, wherein the circuit breaker is prohibited from performing negative control tripping within the preset time period;

[0080] The indication module 34 is configured to, if the request result indicates that the negative control tolerance can be increased, instruct the circuit breaker to adjust the negative control tolerance to the negative control tolerance after adjustment and capacity increase, and perform negative control according to the negative control tolerance after adjustment and capacity increase; and, if the request result indicates that the negative control tolerance cannot be increased or if no reply is received from the superior control center, instruct the circuit breaker to perform negative control tripping according to the negative control tolerance after the preset time period.

[0081] Through the present invention, a circuit breaker is introduced into the control process of regional electricity consumption, and the power load of the electrical equipment is monitored through the circuit breaker. When the power load of the above-mentioned electrical equipment exceeds the negative control tolerance, or the difference between the negative control tolerance and the power load is less than a preset threshold, the circuit breaker is actively used to apply to the superior control center for adjustment and capacity increase to increase the negative control tolerance, and the request result of the superior control center is received within a preset time period, and subsequent operations are performed according to the request result. The above-mentioned technical solution solves the problems of low power supply equipment utilization and power efficiency, which are easy to cause overload tripping, in the control method of regional electricity consumption in related technologies, thereby improving power efficiency and avoiding overload tripping.

[0082] It is understandable that in an embodiment of the present invention, when the circuit breaker detects that the electrical equipment has an extraordinary power demand (that is, the power consumption point where the circuit breaker is located needs to increase power capacity, which can be determined by determining the comparative relationship between the above-mentioned negative control tolerance and the power load), it can actively apply to the superior control center for adjustment and capacity increase, wherein the superior control center includes: a regional coordination control device, a cloud server, and the embodiment of the present invention does not limit this. Then the circuit breaker judges according to the regional coordination control device or the cloud server according to the load situation of the regional power supply and distribution equipment, and the feedback information is to increase the negative control tolerance (of the circuit breaker) or control the electrical equipment to adjust the power load / trend the power load to be controlled below the negative control tolerance. Through the above technical solution, the extraordinary power demand of specific users (which can be understood as the electrical equipment in the above embodiment) can be dynamically met, while ensuring the safety and reliability of power consumption in the region and users, improving the user's power experience, and improving the utilization rate of regional power supply equipment, low power efficiency, overload tripping caused by blind / disordered capacity increase and other problems.

[0083] In order to increase the safety of the adjustment and capacity increase operation, the above-mentioned indication module 34 is further required to perform the following operations: obtain the allowable capacity upper limit corresponding to the circuit breaker; when the load control tolerance has been adjusted to the allowable capacity upper limit, or the power load exceeds the allowable capacity upper limit, instruct the circuit breaker to perform load control tripping according to the allowable capacity upper limit, and prohibit the application for capacity adjustment to the superior control center through the circuit breaker, wherein the allowable capacity upper limit can be understood as the maximum load control tolerance allowed to be set for the circuit breaker, which can be the maximum capacity or rated capacity allowed for the power distribution equipment / power equipment on the line where the circuit breaker is located, or the rated capacity of the circuit breaker. When the power load exceeds the maximum load control tolerance or the load control tolerance has reached the maximum load control tolerance, the circuit breaker must perform load control tripping, and the circuit breaker is not allowed to apply for capacity adjustment to the superior control center again.

[0084] In an embodiment of the present invention, the setting of the preset time period needs to refer to other parameters, and the preset time period is determined by at least one of the following methods: the preset time period is inversely proportional to the negative control tolerance, wherein the larger the negative control tolerance is, the shorter the preset time period is; the smaller the negative control tolerance is, the longer the preset time period is; the preset time period is inversely proportional to the degree of over-limit of the power load, wherein the greater the degree of over-limit is, the shorter the preset time period is; and the smaller the degree of over-limit is, the longer the preset time period is.

[0085] It should be noted that the greater the degree of exceeding the limit (i.e., the more serious the degree of exceeding the limit) can be quantitatively understood in the following ways: the larger the peak value, the larger the mean value, the larger the effective value, the more frequent the occurrence, the longer the cumulative duration, etc. Any of the above situations can be understood as the more serious the degree of exceeding the limit. In addition, the inverse relationship between the preset time period and the negative control tolerance, and the inverse relationship between the preset time period and the degree of exceeding the limit can be achieved through any function that can characterize the inverse relationship, and the embodiments of the present invention are not limited to this.

[0086] Optionally, Figure 4 is another structural block diagram of the dynamic adjustment device for negative control tolerance according to an embodiment of the present invention, such as Figure 4 As shown, the dynamic adjustment device of the load control tolerance in the embodiment of the present invention also includes a monitoring module 36, which is used to reduce the load control tolerance through the circuit breaker after the power load of the electrical equipment drops to the target amount and the time when the power load is at the target amount is maintained for the target time, so as to perform load control according to the reduced load control tolerance. That is to say, if the power load of the electrical equipment has dropped to the target amount and has been maintained at the target amount for a period of time, it can actually be said that the electrical equipment currently has a part of the power capacity quota free, or it can be understood that the power demand has decreased. Then, in order to improve the efficiency of the load control of the circuit breaker and improve the utilization rate of the power supply and distribution equipment, the negative control tolerance of the circuit breaker can be correspondingly reduced, and then negative control can be performed according to the reduced negative control tolerance.

[0087] Optionally, when the power load of the electrical equipment drops to a target amount and it is known that the power load has been shut down or disabled, the load control tolerance may be reduced by the circuit breaker to perform load control according to the reduced load control tolerance.

[0088] It should be noted that, in an optional embodiment, the receiving module 32 is further configured to determine whether the circuit breaker has received a target request instruction; and in response to the target request instruction, apply to the superior control center through the circuit breaker for capacity adjustment and increase to increase the load control margin. Specifically, the receiving module 32 determines whether the circuit breaker has received the target request instruction, which includes at least one of the following: determining whether the circuit breaker has received the target request instruction triggered by a button on the circuit breaker. In this implementation, before the button triggers the target request instruction, the amount of load capacity increase and the duration or period of the load capacity increase can be set in advance, and the above-mentioned target request instruction is triggered according to the amount of load capacity increase and / or the duration or period of the load capacity increase; determining whether the circuit breaker obtains the target request instruction generated by the circuit breaker after recognizing the target voice; and determining whether the circuit breaker has received the target request instruction sent via a mobile terminal, for example, by operating the supporting software of the circuit breaker on a mobile phone / tablet to apply, or by scanning the circuit breaker QR code via a mobile phone / tablet to apply.

[0089] In addition to the above functions, the circuit breaker provided in the embodiment of the present invention can also realize the following functions through the application module 30:

[0090] 1) Passive capacity increase function: The circuit breaker receives a first control instruction sent by the superior control center; in response to the first control instruction, the negative control margin is adjusted to the negative control margin after the capacity increase. That is, the circuit breaker in the embodiment of the present invention passively adjusts the negative control margin after receiving the first control instruction from the superior control center.

[0091] 2) Passive derating function: receiving a second control instruction sent by the superior control center through the circuit breaker; responding to the second control instruction, derating the negative control tolerance through the circuit breaker.

[0092] In an embodiment of the present invention, when the first control instruction and / or the second control instruction carries at least one of the following parameter information: the capacity value adjusted by the negative control tolerance, the adjustment period, the adjustment resource (for example, the electricity capacity price), the circuit breaker is instructed to adjust the negative control tolerance according to the parameter information, and / or determine the resource value to be provided according to the adjustment resource (for example, the billing value corresponding to the electricity capacity price).

[0093] Specifically, the circuit breaker can adjust the negative control tolerance to the target amount according to the capacity value adjusted by the negative control tolerance, can maintain the adjusted negative control tolerance amount within the target time period according to the adjustment period, and can determine the resource value (total amount) to be provided based on the adjustment resources (the amount of each measurement unit).

[0094] 3) Capacity expansion and renewal function: After instructing the circuit breaker to adjust the load control tolerance to the load control tolerance after capacity expansion, the method further includes: when the adjustment period of the load control tolerance adjustment expires, instructing the circuit breaker to automatically apply to the superior control center for renewal based on the power load to maintain the load control tolerance after capacity expansion.

[0095] Specifically, the adjusted load control tolerance is only maintained within the adjustment period. After the adjustment period, the power load has not dropped to the target amount. In this case, in order to continue to maintain the load control tolerance after the adjustment and capacity increase, the circuit breaker will automatically apply to the superior control center for an extension of the period (increase the duration).

[0096] Optionally, the indication module 34 is used to control the electrical equipment to reduce the power load before the negative control tolerance is derated through the circuit breaker, so that the reduced power load is less than the negative control tolerance after the derated adjustment, that is, the method to prevent the circuit breaker from tripping may be to reduce the power load of the electrical equipment to below the negative control tolerance after the proposed derated adjustment.

[0097] Optionally, the indication module 34 is used to receive a power demand response instruction through the circuit breaker; in response to the power demand response instruction, control the power equipment to reduce the power load and / or reduce the load control tolerance according to the power load priority control strategy stored in the circuit breaker.

[0098] Optionally, the instruction module 34 is configured to adjust the power load of the electrical equipment so that the adjusted power load is less than the negative control tolerance when the request result indicates that the negative control tolerance is not allowed to be increased or when no response is received from the superior control center.

[0099] Optionally, the receiving module 32 is used to receive a third control instruction sent by a target object through the circuit breaker, wherein the target object includes at least one of the following: a mobile client, a mobile applet, a superior circuit breaker, a smart meter, and a smart electricity monitoring terminal; in response to the third control instruction, perform at least one of the following operations on the electrical equipment: switch control, closing and locking.

[0100] That is, the smart circuit breaker receives the APP / applet of the mobile terminal, or the control instructions of the superior household smart circuit breaker / smart meter / smart electricity monitoring terminal, and performs operations such as switching and locking of conventional electrical equipment.

[0101] Optionally, the indication module 34 is configured to, when the circuit breaker receives a third control instruction for indicating a closing lock, prohibit the circuit breaker from performing a closing operation, and / or control a tripping mechanism in the circuit breaker to be in a tripped state, so that the circuit breaker cannot be in a closed state or a closed position (i.e., cannot be closed manually or remotely).

[0102] Optionally, the indication module 34 is configured to control the internal trip of the circuit breaker to reset so that the circuit breaker can be closed when the circuit breaker receives a fourth control instruction for indicating release of locking.

[0103] It can be seen that in the embodiment of the present invention, the circuit breaker can realize coordinated regulation of the switches and power consumption of the user's internal electrical equipment (including smart electrical equipment, smart circuit breakers that supply power to conventional electrical equipment, electrical equipment monitoring terminals, etc.) at the user's power consumption gateway based on the load control tolerance and dynamic adjustment process, so that the total load of the electrical equipment is not overloaded.

[0104] 4) Communication function: Establish a connection with the circuit breaker through the circuit breaker client or applet; based on the established connection, implement data interaction between the circuit breaker and the circuit breaker client or applet, or instruct the circuit breaker to interact with the upper control center based on the connection.

[0105] That is, in this communication function, the APP or applet of the mobile terminal can connect to the circuit breaker via Bluetooth, and then monitor the circuit breaker operation data information through the APP or applet to implement auxiliary capacity expansion, load reduction control, modification of capacity expansion / derating related parameter configuration and other processes; in addition, the circuit breaker can use the network of the mobile terminal to indirectly communicate with the regional coordination control device or cloud server, etc., to transmit data, send requests or receive instructions, thereby solving the problems of high cost, difficult construction and weak signal coverage when the circuit breaker directly uses wired communication or wireless networking.

[0106] In summary, circuit breakers can add dynamic load control adjustment functions through embedded software to realize active capacity increase application, active capacity reduction, auxiliary capacity increase, passive capacity increase, passive capacity reduction, etc. In addition, they can also cooperate with APP, regional coordination control devices or cloud servers to dynamically adjust their load control tolerance.

[0107] In other words, through the technical solutions described in the embodiments of the present invention, the monitoring terminal and circuit breaker are highly integrated (which can be understood as the fusion of primary and secondary equipment, forming an intelligent switch), simplifying the system, reducing size, and lowering costs. The smart meter / smart electricity monitoring terminal + home switch, along with the power supply switch and its locking mechanism + power supply monitoring terminal of the terminal electrical equipment, are all integrated into one, achieving an integrated solution.

[0108] Through the technical solution of the present invention, when the capacity balance of a user sub-area is less than the load power of the electrical equipment to be enabled in the user sub-area, the circuit breaker requests the regional coordination control device or server to adjust and increase the capacity of the user sub-area so that the capacity balance is greater than or equal to the load power, and then determines whether to enable the electrical equipment based on the request result fed back by the regional coordination control device or server. The above technical solution solves the problems of low utilization rate of power supply equipment and low power efficiency in regional power control methods in related technologies, which easily cause overload tripping, and further, for electrical equipment whose capacity balance cannot meet the load power, it is possible to flexibly request the regional coordination control device or server to adjust and increase the capacity of the user sub-area through the circuit breaker so that the capacity balance is greater than or equal to the load power, thereby improving power efficiency and avoiding overload tripping.

[0109] Dynamic load adjustment control can flexibly control the user's power capacity quota and / or the user's power equipment load according to the load or load demand of the regional power supply and distribution equipment: the circuit breaker's negative control tolerance is used to control the power capacity of the user's sub-region. When the circuit breaker detects that the user has extraordinary power demand (power capacity increase is required), it can actively apply for and increase the negative control tolerance (capacity increase) for the circuit breaker based on the information (such as the load situation of the regional power supply and distribution equipment) judged / feedback by the regional coordination control device or cloud server, or control the power equipment to adjust the power load / trend to keep it below the negative control tolerance. Dynamically meet the extraordinary power demand of specific users, while ensuring the safety and reliability of power supply in the region and users, improving the user's power experience, and improving problems such as low utilization / power efficiency of regional power supply equipment and overload tripping caused by blind / disorderly capacity increase.

For the latter, it can be implemented in the following ways, but not limited to: the above modules are all located in the same processor; or the above modules are located in different processors in any combination.
