It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0030] Before introducing the circuit breaker control method provided by the present application in detail, a brief introduction to the application scenarios involved in the present application is first given.

[0031] In the field of circuit breaker technology, electronic circuit breakers are new protection devices in automation equipment. Compared with traditional air switches, they have the characteristics of fast response speed and adjustable protection current, and have completely replaced traditional air switches in the field of low voltage protection. In addition, since electronic circuit breakers have the characteristics of more than one pound, they can replace some terminals and reduce customer costs.

[0032] In the related art, electronic circuit breakers can only estimate the load size through status indications and cannot accurately set the protection current.

[0033] Before introducing the circuit breaker control method provided by the present application in detail, a brief introduction to the implementation environment (implementation architecture) involved in the present application is first given.

[0034] The circuit breaker control method provided in the embodiment of the present application can be applicable to a circuit breaker. Figure 1 A schematic diagram of the structure of the circuit breaker is shown in FIG. Figure 1 As shown, the circuit breaker 10 includes a display screen, an output terminal, an input terminal, and a button. Among them, the circuit breaker is provided with 10 digital buttons including 1-10, and the button S is a first function button, and the button E is a second function button. When the circuit breaker enters the output current setting mode or the output voltage setting mode, the digital button 9 is a preset increase button, and the digital button 10 is a preset decrease button.

[0035] Figure 21 is a flow chart of a circuit breaker control method according to an exemplary embodiment. The method can be applied to a circuit breaker. The following takes the method applied to a circuit breaker as an example to illustrate the method. Figure 1 As shown, the circuit breaker control method includes the following steps:

[0036] S101: In response to a long press operation on a first function button, the circuit breaker enters an output current setting mode of the circuit breaker.

[0037] As a possible implementation, the commissioning personnel long presses the first function key on the keyboard of the circuit breaker. Accordingly, the circuit breaker enters the output current setting mode of the circuit breaker in response to the long press operation on the first function key.

[0038] As above Figure 1 As shown, the first function button is the S button. In actual process, the circuit breaker enters the output current setting mode of the circuit breaker in response to the operation of pressing the S button for 4 seconds.

[0039] S102 . When in an output current setting mode, the circuit breaker sets the first current value as an output current value of a first channel of the circuit breaker in response to an input first current value.

[0040] As a possible implementation, when in the output current setting mode, the commissioning personnel inputs a first current value on the keyboard of the circuit breaker. Accordingly, the circuit breaker responds to the input first current value and sets the first current value as the output current value of the first channel of the circuit breaker.

[0041] S103: In response to the tapping operation on the first function button, the circuit breaker switches the output current setting modes of other channels in sequence.

[0042] As a possible implementation, after setting the output current value of the first channel, the operator performs a tap operation on the first function button. Accordingly, the circuit breaker switches the output current setting modes of other channels in sequence in response to the tap operation on the first function button.

[0043] Exemplarily, after setting the output current value of the first channel, the operator performs a tap operation on the first function button, and accordingly, the circuit breaker switches to the output current setting mode of the second channel.

[0044] S104 . In response to the input second current value, the circuit breaker sets the second current value as the output current value of the channel corresponding to the second current value.

[0045] Exemplarily, when the second current value is input after the second channel enters the output current setting mode, the circuit breaker sets the second current value as the output current value of the second channel.

[0046] When the second current value is input after the fifth channel enters the output current setting mode, the circuit breaker sets the second current value as the output current value of the fifth channel.

[0047] It can be understood that the technical solution provided by the embodiment of the present application enters the output current setting mode of the circuit breaker by responding to the long press operation of the first function button; when in the output current setting mode, in response to the input first current value, the first current value is set as the output current value of the first channel of the circuit breaker; in response to the tap operation of the first function button, the output current setting modes of other channels are switched in sequence; in response to the input second current value, the second current value is set as the output current value of the channel corresponding to the second current value. In this way, by setting the output current setting mode, compared with only estimating the size of the load through the status indication, not only can the current value of each channel be accurately set in sequence, but also the use cost can be reduced by directly inputting the current value.

[0048] In some embodiments, in order to be able to adjust the undervoltage threshold and overvoltage threshold of each channel of the circuit breaker, such as Figure 3 As shown, the circuit breaker control method provided in the embodiment of the present application further includes the following steps:

[0049] S201: The circuit breaker enters an output voltage setting mode of the circuit breaker in response to a long press operation on a first function button and a short press operation on a second function button.

[0050] As a possible implementation, the commissioning personnel performs a long press operation on the first function button, and accordingly, the circuit breaker enters the output current setting mode.

[0051] Furthermore, the debugging personnel performs a tap operation on the second function button, and accordingly, the circuit breaker enters the output voltage setting mode.

[0052] As shown in the figure above, button E is the second function button.

[0053] S202 : When in output voltage setting mode, adjust the undervoltage threshold and overvoltage threshold of the first channel according to a preset increase button and a preset decrease button.

[0054] As a possible implementation, when in the output voltage setting mode, the undervoltage threshold of the first channel flashes on the screen, and the undervoltage threshold of the first channel is first adjusted according to a preset increase button and a preset decrease button.

[0055] Further, the debugging personnel short presses the first function button. Accordingly, the circuit breaker responds to the short press operation of the first function button and controls the overvoltage threshold of the first channel to flash on the screen. At this time, the debugging personnel adjusts the overvoltage threshold of the first channel through the preset increase button and the preset decrease button.

[0056] S203: In response to the tapping operation on the first function button, the circuit breaker sequentially switches the output voltage setting modes of other channels and sequentially adjusts the undervoltage threshold and overvoltage threshold of other channels.

[0057] As a possible implementation manner, the debugger performs a tap operation on the first function button, and the circuit breaker switches the undervoltage threshold and the overvoltage threshold of each channel in sequence.

[0058] The debugger can make adjustments through the preset increase button and the preset decrease button.

[0059] As another possible implementation, the debugger performs a tap operation on the first function button, and the circuit breaker switches the undervoltage threshold of each channel in sequence, and then switches the overvoltage threshold of each channel in sequence.

[0060] The debugger can make adjustments through the preset increase button and the preset decrease button.

[0061] As another possible implementation, the debugger performs a tap operation on the first function button, and the circuit breaker switches the overvoltage threshold of each channel in sequence. Then, the overvoltage threshold of each channel is switched in sequence again.

[0062] The debugger can make adjustments through the preset increase button and the preset decrease button.

[0063] Exemplarily, the setting range of the overvoltage threshold may be 30 volts to 33 volts. When the voltage is higher than the set voltage value, the output of the corresponding channel is turned off.

[0064] The undervoltage threshold can be set in the range of 16V-18V. When the voltage is lower than the set voltage value, the output of the corresponding channel is turned off.

[0065] It can be understood that the technical solution provided by the embodiment of the present application enters the output voltage setting mode of the circuit breaker by responding to the long press operation of the first function button and the tap operation of the second function button; when in the output voltage setting mode, the undervoltage threshold and overvoltage threshold of the first channel are adjusted according to the preset increase button and the preset decrease button; in response to the tap operation of the first function button, the output voltage setting modes of other channels are switched in turn, and the undervoltage threshold and overvoltage threshold of other channels are adjusted in turn. In this way, the undervoltage threshold and overvoltage threshold can be set according to the actual needs of each channel, and the equipment under each channel can be further protected.

[0066] In some embodiments, the circuit breaker control method provided by the embodiments of the present application further includes the circuit breaker switching the output state of any channel in response to a tap operation on a key corresponding to any channel.

[0067] For example, when the circuit breaker is in the default state, the debugging personnel can switch whether channel 4 turns on the channel output by pressing the button corresponding to channel 4.

[0068] In some embodiments, Figure 4 As shown, the circuit breaker control method provided in the embodiment of the present application further includes the following steps:

[0069] S301: The circuit breaker determines whether it is in an output current setting mode or an output voltage setting mode and has not been operated within a preset time period.

[0070] S302: When the circuit breaker is in the output current setting mode or the output voltage setting mode and no operation is performed within a preset time period, the circuit breaker exits the output current setting mode or the output voltage setting mode and saves the current setting.

[0071] Exemplarily, when the circuit breaker is in the output current setting mode or the output voltage setting mode and the keyboard is not operated within 10 seconds, the circuit breaker exits the output current setting mode or the output voltage setting mode and saves the current setting.

[0072] The above mainly introduces the solution provided by the embodiment of the present application from the perspective of the method. In order to achieve the above functions, the circuit breaker or electronic device includes a hardware structure and / or software module corresponding to the execution of each function. It should be easily appreciated by those skilled in the art that, in combination with the units and algorithm steps of each example described in the embodiments disclosed herein, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of the present application.

[0073] The embodiment of the present application can divide the functional modules of the circuit breaker or electronic device according to the above method. For example, the circuit breaker or electronic device can include various functional modules corresponding to the functional divisions, or two or more functions can be integrated into one processing module. The above integrated modules can be implemented in the form of hardware or in the form of software functional modules. It should be noted that the division of modules in the embodiment of the present application is schematic and is only a logical functional division. There may be other division methods in actual implementation.

[0079] The processing unit 401 is further configured to set the second current value as the output current value of the channel corresponding to the second current value in response to the input second current value.

[0081] In response to a long press operation on the first function button and a short press operation on the second function button, the output voltage setting mode of the circuit breaker is entered.

[0082] When in the output voltage setting mode, the undervoltage threshold and overvoltage threshold of the first channel are adjusted according to the preset increase button and the preset decrease button.

[0083] In response to the tapping operation on the first function key, the output voltage setting modes of other channels are switched in sequence, and the undervoltage thresholds and overvoltage thresholds of other channels are adjusted in sequence.

[0084] Optional, such as Figure 5 As shown, the processing unit 401 provided in the embodiment of the present application is also used for:
