[0019] Explanation of reference numerals in the attached figures Parameter setting device 300 Parameter setting component 310 First regulating mechanism 311 Second regulating mechanism 312 Signal conversion unit 320 Microprocessor 330 First rotary encoder switch 401 Second rotary encoder switch 402 First DIP switch 501 Second DIP switch 502 Third DIP switch 701 Detailed Implementation The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0020] As described in the background section, the operation of current circuit breaker products depends on the setting of relevant parameters. In the prior art, the relevant parameters of circuit breaker products are generally set through coded switches or DIP switches.

[0021] Taking an encoder switch as an example, the parameter tuning scheme based on the encoder switch can be as follows: Figure 1 As shown, where I r This is the long-delay overload protection current setting value, through the rated current I. n Multiples of (×I) n ) indicates; I sd This is the short-delay short-circuit protection current setting value, determined by I. r Multiples of (×I) r ) indicates; I i The instantaneous short-circuit protection current setting value is determined by I. n Multiples of (×I) n ) indicates; T r This is the long delay protection time setting value, in seconds (s); T sd This is the short-delay protection time setting value, in seconds (s). Each parameter can be set using the corresponding encoder switch. It can be seen that the encoder switch for each parameter provides a limited number of settings, resulting in a very limited range of selectable parameter settings. This makes the parameter setting method in the existing parameter setting scheme inflexible.

[0022] The parameter tuning method based on DIP switches follows the same principle. In this method, a separate DIP switch is set for each parameter, and the parameter value is controlled by controlling the state of the DIP switch. For example... Figure 2 The example shown is for I r The DIP switch setting for this parameter is limited by the number of states that the DIP switch can provide, resulting in insufficient selectable parameter settings.

[0023] Therefore, current parameter tuning schemes cannot provide a flexible and comprehensive parameter setting solution.

[0024] To address the aforementioned problems, this disclosure provides a parameter setting device and an electronic circuit breaker.

[0025] Figure 3 This is a block diagram of a parameter setting device provided according to an embodiment of the present disclosure. Figure 3As shown, the parameter setting device 300 provided in this disclosure may include a parameter setting component 310, a signal conversion unit 320, and a microprocessor 330. Wherein: The parameter setting component 310 includes a first adjustment mechanism 311 and a second adjustment mechanism for setting target parameters; the first adjustment mechanism 311 and the second adjustment mechanism 312 are provided with multiple adjustment contacts. The signal conversion unit 320 is connected to the parameter setting component 310 and is used to convert the on / off state of each adjustment contact of the first adjustment mechanism 311 and the second adjustment mechanism 312 into an electrical signal. The microprocessor 330, connected to the signal conversion unit 320, is used to determine the parameter value of the target parameter based on the electrical signal.

[0026] In this disclosure, the target parameter can be any parameter that needs to be set, such as I mentioned above. r I sd I i T r T sd Or other adjustable parameters not shown. For multiple parameters, multiple parameter setting components 310 of this disclosure can be provided to set each parameter separately. When multiple parameter setting components 310 are provided, the signal conversion unit 320 and the microprocessor 330 can process each parameter setting component 310 separately and finally obtain the parameter value corresponding to each parameter.

[0027] The first adjustment mechanism 311 can use a first value as the smallest adjustment unit, and the second adjustment mechanism 312 can use a second value as the smallest adjustment unit, where the first value is greater than the second value. By setting these smallest adjustment units, such as the first and second values, different granularities of parameter adjustment can be provided. For example, the first value can be 0.1, used to adjust the parameter value corresponding to the first decimal place, and the second value can be 0.01, used to adjust the parameter value corresponding to the second decimal place.

[0028] It should be noted that one or more second adjustment mechanisms can be set according to actual needs. When more than one second adjustment mechanism is set, the second value of each second adjustment mechanism can be adjusted as needed according to the required precision. For example, the first adjustment mechanism can be set with a minimum adjustment unit of 0.1, the first second adjustment mechanism can be set with a minimum adjustment unit of 0.01, and the second second adjustment mechanism can be set with a minimum adjustment unit of 0.001.

[0029] In one possible embodiment, such as Figure 4As shown, the first adjustment mechanism can be a first rotary encoder switch 401, and the second adjustment mechanism can be a second rotary encoder switch 402. The first rotary encoder switch 401 and the second rotary encoder switch 402 are respectively connected to the signal conversion unit 320.

[0030] The first rotary encoder switch 401 may include a first adjustment knob, which is used to switch between multiple first parameter levels. Each first parameter level corresponds to an adjustment contact and a parameter value, and the difference between the parameter values ​​of adjacent first parameter levels is a first value.

[0031] refer to Figure 4 The first rotary encoder switch 401 provides first parameter levels of 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, and 1.0, corresponding to parameter values ​​of 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, and 1.0, respectively. Each first parameter level has an adjustment contact. Rotating the first adjustment knob by one first parameter level adjusts the parameter value by 0.1 (i.e., the first value).

[0032] The second rotary encoder switch 402 includes a second adjustment knob, which is used to switch between multiple second parameter levels. Each second parameter level corresponds to an adjustment contact and a parameter value. The difference between the parameter values ​​of adjacent second parameter levels is the second value.

[0033] refer to Figure 4 The second rotary encoder switch 402 provides two second parameter positions: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9, corresponding to parameter values ​​of 0.00, 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, and 0.09, respectively. Each second parameter position has an adjustment contact. Rotating the second adjustment knob one second parameter position adjusts the parameter value by 0.01 (i.e., the second value).

[0034] The signal conversion unit 320 generates a first electrical signal based on the on / off state of the adjustment contacts of each first parameter level, and generates a second electrical signal based on the on / off state of the adjustment contacts of each second parameter level, and transmits the first and second electrical signals to the microprocessor 330.

[0035] The microprocessor 330 is used to determine the parameter value of the target parameter based on the first electrical signal and the second electrical signal.

[0036] Optionally, the signal conversion unit 320 can use a conventional gear reading circuit. For example, for each gear corresponding to the adjustment contact, a pull-up resistor is used to set the adjustment contact to a high level in the default open state, and pulls it down to a low level when the adjustment contact is connected (or closed). The microprocessor 330 can detect which contact is connected by detecting the GPIO (General Purpose Input Output) status, and thus determine which parameter gear is selected.

[0037] Therefore, the signal conversion unit 320 can convert the on / off state of each adjusting contact in the first rotary encoder switch 401 into a first electrical signal and transmit it to the microprocessor 330, and can convert the on / off state of each adjusting contact in the second rotary encoder switch 402 into a second electrical signal and transmit it to the microprocessor 330. By processing the first and second electrical signals, the microprocessor 330 can determine the selected parameter level in each of the first and second rotary encoder switches 401 and 402.

[0038] Based on this, the microprocessor 330 can determine the selected parameter value according to the first electrical signal and the second electrical signal, and then integrate and add them to obtain the parameter value of the target parameter. Figure 4 For example, assuming that the first parameter setting of 0.5 in the first rotary encoder switch 401 is selected (corresponding to 0.5), and the second parameter setting of 2 in the second rotary encoder switch 402 is selected (corresponding to 0.02), the target parameter I can be determined. r The final parameter value is 0.5I. n +0.02I n =0.52I n Substitute I directly n The actual value is sufficient.

[0039] In another possible embodiment, the first adjustment mechanism can be a first DIP switch 501, and the second adjustment mechanism can be a second DIP switch 502. The first DIP switch 501 and the second DIP switch 502 are respectively connected to the signal conversion unit 320.

[0040] The first DIP switch 501 may include a first number of switching devices, and the second DIP switch 502 may include a second number of switching devices, each switching device having at least two adjustment contacts. For example, the first number may be 3, and the second number may be 4.

[0041] Each switching device can switch between at least two corresponding adjustment contacts. The first and second quantities can be set by combining the number of adjustment contacts for each switching device and the number of parameters to be set. For example, if each switching device corresponds to two adjustment contacts, and the eight states of the first DIP switch 501 represent the eight parameters to be set, considering 2... 3 =8 indicates that setting 3 switching devices is sufficient to meet the required parameter quantity. Therefore, the first DIP switch 501 can be configured to include 3 switching devices.

[0042] refer to Figure 5 The diagram shows a first DIP switch 501 comprising three switching devices, a second DIP switch 502 comprising four switching devices, and each switching device corresponding to two adjustment contacts. By switching each switching device between its corresponding adjustment contacts, the states of the first DIP switch 501 and the second DIP switch 502 can be adjusted.

[0043] Optionally, a first mapping relationship between the state of the first DIP switch 501 and a first parameter value, and a second mapping relationship between the state of the second DIP switch 502 and a second parameter value can be preset. The difference between adjacent first parameter values ​​is the first value, and the difference between adjacent second parameter values ​​is the second value. Optionally, the first and second mapping relationships can be stored in the microprocessor 330. For example, the setting of the first and second mapping relationships can be referenced... Figure 6 This mapping relationship can be displayed as a prompt message near the first DIP switch 501 and the second DIP switch 502.

[0044] The signal conversion unit 320 is used to generate a fourth electrical signal according to the on / off state of each adjustment contact in the first DIP switch 501, and to generate a fifth electrical signal according to the on / off state of each adjustment contact in the second DIP switch 502, and transmit the fourth and fifth electrical signals to the microprocessor 330.

[0045] The microprocessor 330 is used to determine the parameter value of the target parameter based on the fourth and fifth electrical signals.

[0046] The principle of the signal conversion unit 320 for switching the on / off states of each adjustment contact in the first DIP switch 501 and the second DIP switch 502 is similar to the previous description of the signal conversion unit 320, and will not be repeated here.

[0047] The signal conversion unit 320 can convert the on / off state of each adjustment contact in the first DIP switch 501 into a fourth electrical signal and transmit it to the microprocessor 330, and can convert the on / off state of each adjustment contact in the second DIP switch 502 into a fifth electrical signal and transmit it to the microprocessor 330. By processing the fourth and fifth electrical signals, the microprocessor 330 can determine the current state of the first DIP switch 501 and the current state of the second DIP switch 502.

[0048] Based on this, the microprocessor 330 can determine the first parameter value corresponding to the state represented by the fourth electrical signal according to the fourth electrical signal and the first mapping relationship, and determine the second parameter value corresponding to the state represented by the fifth electrical signal according to the fifth electrical signal and the second mapping relationship. Then, by integrating and adding the two values, the parameter value of the target parameter can be obtained. Figure 6 For example, suppose the first DIP switch 501 and the second DIP switch 502 are respectively in the following positions: Figure 6 As shown by the dashed ellipse, the first parameter value corresponding to the first DIP switch 501 is 0.6, and the second parameter value corresponding to the second DIP switch 502 is 0.03. Therefore, the target parameter I can be determined. r The final parameter value is 0.6I. n +0.03I n =0.63I n Substitute I directly n The actual value is sufficient.

[0049] In another possible embodiment, the first adjustment mechanism and the second adjustment mechanism can be composed of a third DIP switch 701, that is, the adjustment functions of the first adjustment mechanism 311 and the second adjustment mechanism 312 are realized through the third DIP switch 701. The third DIP switch 701 is connected to the signal conversion unit 320.

[0050] The third DIP switch 701 may include a third number of switching devices, each of which may correspond to at least two adjustment contacts. For example, the third number may be 5.

[0051] Each switching device can switch between at least two corresponding adjustment contacts. The third quantity can be set by combining the number of adjustment contacts for each switching device and the number of parameters to be set. For example, if each switching device corresponds to two adjustment contacts, and 30 parameters need to be set using the 30 states of the third DIP switch 701, considering 2... 4 =16<30,2 5 =32>30, which means that at least 5 switching devices are needed to meet the required parameter quantity. Therefore, the third DIP switch 701 can be set to include 5 switching devices.

[0052] refer to Figure 7 The diagram shows a third DIP switch 701 comprising five switching devices, each with two adjustment contacts. The state of the third DIP switch 701 can be adjusted by switching each switching device between its corresponding adjustment contacts.

[0053] Optionally, a third mapping relationship between the state of the third DIP switch 701 and the value of the third parameter can be preset. The difference between adjacent third parameter values ​​is a second value or a multiple of the second value, and should be less than the first value. For example, if the second value is 0.01, the third parameter value can be 0.01, 0.02, etc. Optionally, the third mapping relationship can be stored in the microprocessor 330. For example, the setting of the third mapping relationship can refer to... Figure 8 This mapping relationship can be displayed as a prompt near the third DIP switch 701.

[0054] The signal conversion unit 320 is used to generate a sixth electrical signal according to the on / off state of each adjustment contact in the third DIP switch 701, and transmit the sixth electrical signal to the microprocessor 330.

[0055] The microprocessor 330 is used to determine the parameter value of the target parameter based on the sixth electrical signal.

[0056] The principle of the signal conversion unit 320 for switching the on / off states of each adjustment contact in the third DIP switch 701 is similar to the previous description of the signal conversion unit 320, and will not be repeated here.

[0057] The signal conversion unit 320 can convert the on / off state of each adjustment contact in the third DIP switch 701 into a sixth electrical signal, which is then transmitted to the microprocessor 330. By processing the sixth electrical signal, the microprocessor 330 can determine the current state of the third DIP switch 701.

[0058] Based on this, the microprocessor 330 can determine the value of the third parameter corresponding to the state represented by the sixth electrical signal according to the sixth electrical signal and the third mapping relationship, and thus obtain the parameter value of the target parameter. Figure 8 For example, suppose the third DIP switch 701 is in the position... Figure 8 The state shown by the dashed ellipse indicates that the third parameter value corresponding to the third DIP switch 701 is 0.48, and thus the target parameter I can be determined. r The final parameter value is 0.48I. n Substitute I directly n The actual value is sufficient.

[0059] The above technical solution provides a parameter setting component, a signal conversion unit connected to the parameter setting component, and a microprocessor connected to the signal conversion unit in the parameter setting device. The parameter setting component includes a first adjustment mechanism and a second adjustment mechanism, which are used together to set the target parameter. Each of the first and second adjustment mechanisms has multiple adjustment contacts. The on / off state of each adjustment contact reflects the parameter setting status. The signal conversion unit converts the on / off signals of the adjustment contacts into electrical signals, which are then integrated by the microprocessor to obtain the final target parameter value. The first adjustment mechanism uses a first value as the smallest adjustment unit, and the second adjustment mechanism uses a second value as the smallest adjustment unit, with the first value being greater than the second value. Therefore, by providing different parameter adjustment granularities through the first and second adjustment mechanisms, the parameter setting accuracy can be set as needed, which is beneficial for improving parameter setting precision.

[0060] In an optional embodiment, the parameter setting device 300 may further include an operating mode setting component. The operating mode setting component may be connected to the signal conversion unit 320.

[0061] The operating mode setting component is used to set the operating mode of the parameter setting device 300. The operating mode can include a local setting mode and a remote setting mode. In remote setting mode, the settings of the parameter setting component 310 can be ignored, meaning the target parameter can be set through other means. In local setting mode, the target parameter needs to be determined based on the settings of the parameter setting component 310. Optionally, the local setting mode and the remote setting mode can correspond to different states of the operating mode setting component, respectively.

[0062] The signal conversion unit 320 is used to transmit electrical signals representing the operating mode to the microprocessor 330.

[0063] The microprocessor 330 is used to determine the parameter value of the target parameter through the electrical signal corresponding to the parameter setting component 310 when the parameter setting device 300 is in the local setting mode.

[0064] The signal conversion unit 320 can convert the state of the operating mode setting component into an electrical signal and transmit it to the microprocessor 330. The microprocessor 330 can determine the operating mode of the parameter setting device 300 by receiving the electrical signal. If the microprocessor 330 determines through the electrical signal that the operating mode setting component sets the operating mode of the parameter setting device 300 to the local setting mode, it determines the parameter value of the target parameter through the electrical signal corresponding to the parameter setting component 310, that is, it determines the parameter value of the target parameter through the combination of the first adjustment mechanism and the second adjustment mechanism as provided in the previous embodiments.

[0065] In another alternative embodiment, the parameter setting device 300 may further include a communication interface connected to the microprocessor 330.

[0066] The microprocessor 330 is also used to obtain the parameter value of the target parameter through the communication interface when the operating mode is remote setting mode.

[0067] When the microprocessor 330 determines, based on the received electrical signal characterizing the operating mode, that the operating mode setting component sets the operating mode of the parameter setting device 300 to remote setting mode, it can obtain the parameter value of the target parameter through the communication interface connected to the microprocessor 330. In this case, it is not necessary to refer to the settings of the first adjustment mechanism and the second adjustment mechanism.

[0068] In one possible embodiment, the operating mode setting component can be implemented via a single DIP switch or button, such as... Figure 9 Component K in the system provides a local setup mode K1 and a remote setup mode K2.

[0069] In another possible embodiment, if the first adjustment mechanism is a first rotary encoder switch 401 and the second adjustment mechanism is a second rotary encoder switch 402, the first rotary encoder switch 401 or the second rotary encoder switch 402 can be set as a working mode setting component. A position for enabling the remote working mode is set in addition to the first parameter position or the second parameter position, and there is a corresponding adjustment contact. The on / off state of the adjustment contact can be switched by the signal conversion unit 320.

[0070] If the microprocessor 330 detects through the signal conversion unit 320 that either the first rotary encoder switch 401 or the second rotary encoder switch 402 is in the remote working mode, then the parameter setting device 300 can be determined to be operating in the remote setting mode. If the microprocessor 330 detects through the signal conversion unit 320 that neither the first rotary encoder switch 401 nor the second rotary encoder switch 402 is in the remote working mode, then the parameter setting device 300 can be determined to be operating in the local setting mode.

[0071] In another possible embodiment, if the first adjustment mechanism is a first DIP switch 501 and the second adjustment mechanism is a second DIP switch 502, then the operating mode setting component can be either the first DIP switch 501 or the second DIP switch 502.

[0072] The first target state of either the first DIP switch 501 or the second DIP switch 502 corresponds to the remote setting mode. Optionally, the first target state and the remote setting mode can form a mapping relationship and be stored in the microprocessor 330. For example, if the operating mode setting component is the second DIP switch 502, the first target state can be as follows: Figure 6 As shown in B3.

[0073] The microprocessor 330 is used to determine that the operating mode of the parameter setting device 300 is a remote setting mode when the operating mode setting component is determined to be in the first target state by the fourth electrical signal or the fifth electrical signal; the microprocessor 330 is also used to determine that the operating mode of the parameter setting device 300 is a local setting mode when the operating mode setting component is not determined to be in the first target state by the fourth electrical signal or the fifth electrical signal.

[0074] In other words, the microprocessor 330 can determine whether the working mode setting component is in the first target state based on the fourth or fifth electrical signal and the first target state. If the working mode setting component is in the first target state, the working mode of the parameter setting device 300 can be determined to be the remote setting mode; otherwise, the working mode of the parameter setting device 300 can be determined to be the local setting mode.

[0075] In another possible embodiment, if the first adjustment mechanism and the second adjustment mechanism are composed of a third DIP switch 701, then the operating mode setting component can be the third DIP switch 701.

[0076] The third target state of the third DIP switch 701 corresponds to the remote setting mode. Optionally, the third target state and the remote setting mode can form a mapping relationship and be stored in the microprocessor 330. For example, if the operating mode setting component is the third DIP switch 701, the third target state can be as follows: Figure 8 As shown in B4.

[0077] The microprocessor 330 is used to determine that the operating mode of the parameter setting device 300 is the remote setting mode when the third DIP switch 701 is determined to be in the third target state by the sixth electrical signal; the microprocessor 330 is also used to determine that the operating mode of the parameter setting device 300 is the local setting mode when the operating mode setting component is not in the third target state by the sixth electrical signal.

[0078] In other words, the microprocessor 330 can determine whether the operating mode setting component is in the third target state based on the sixth electrical signal and the third target state. If the operating mode setting component is in the third target state, the operating mode of the parameter setting device 300 can be determined to be the remote setting mode; otherwise, the operating mode of the parameter setting device 300 can be determined to be the local setting mode.

[0079] By using the above methods, while providing parameter setting functions, both a local setting mode, which allows settings to be made based on parameter setting components, and a remote setting mode, which allows parameters to be set or modified directly through the communication interface, are provided. The setting methods are more flexible and can better adapt to more setting scenarios.

[0080] In one possible embodiment, when the first adjustment mechanism is a first rotary encoder switch 401 and the second adjustment mechanism is a second rotary encoder switch 402, the target rotary encoder switch may be configured with a function level corresponding to a preset function, which may be connected to the signal conversion unit 320. For example, the preset function may be an alarm function. The target rotary encoder switch is either the first rotary encoder switch 401 or the second rotary encoder switch 402.

[0081] Each function level can have a corresponding adjustment contact. For example, the function levels can be as follows: Figure 4 As shown in A1, in this example, the target rotary encoder switch is the first rotary encoder switch 401.

[0082] A function level can be associated with a first parameter level and a second parameter level. Optionally, the parameter values ​​corresponding to the first and second parameter levels associated with a function level can be indicated by identifiers, such as... Figure 4 As shown in the solid line box, the function level is associated with parameter 1.0 corresponding to the first parameter level and parameter 0.00 corresponding to the second parameter level.

[0083] The signal conversion unit 320 is used to generate a third electrical signal when the adjustment contact corresponding to the function position is connected, and transmit the third electrical signal to the microprocessor 330.

[0084] The microprocessor 330 is used to determine the parameter value of the target parameter based on the parameter value corresponding to the first parameter level associated with the function level represented by the third electrical signal and the parameter value corresponding to the second parameter level associated with the function level when the third electrical signal is received.

[0085] The principle of the signal conversion unit 320 for switching the on / off state of the adjustment contact is similar to that described above, and will not be repeated here.

[0086] The signal conversion unit 320 can obtain a corresponding third electrical signal when the adjustment contact corresponding to the function position is connected and transmit it to the microprocessor 330. The microprocessor 330 determines the selected function position of the target rotary encoder switch based on the third electrical signal, and then determines the parameter value of the target parameter based on the parameter values ​​corresponding to the first and second parameter positions associated with the function position. (Reference) Figure 4 If the target rotary encoder switch is in the function position, the target parameter I can be determined based on the parameter 1.0 corresponding to the first parameter position and the parameter 0.00 corresponding to the second parameter position. r The final parameter value is 1.00I. n Substitute I directly n The actual value is sufficient.

[0087] In another possible embodiment, when the first adjustment mechanism is a first rotary encoder switch 401 and the second adjustment mechanism is a second rotary encoder switch 402, the first DIP switch 501 or the second DIP switch 502 can correspond to a preset function in the second target state. For example, the second target state can be as follows: Figure 6 As shown in A2.

[0088] The preset function can be associated with the parameter value corresponding to the first state of the first DIP switch 501 and the parameter value corresponding to the second state of the second DIP switch 502. Optionally, the parameter values ​​corresponding to the first state of the first DIP switch 501 and the parameter values ​​corresponding to the second state of the second DIP switch 502 associated with the preset function can be indicated by identifiers, such as... Figure 6 As shown in the solid box, the preset function is associated with the parameter value 1.0 corresponding to the first state of the first DIP switch 501 and the parameter value 0.00 corresponding to the second state of the second DIP switch 502. For example, the preset function can be an alarm function.

[0089] The microprocessor 330 is used to determine the parameter value of the target parameter based on the parameter value corresponding to the first state and the parameter value corresponding to the second state when the first DIP switch 501 is determined to be in the second target state by the fourth electrical signal or the second DIP switch 502 is determined to be in the second target state by the fifth electrical signal.

[0090] The principle of the signal conversion unit 320 for switching the on / off state of the adjustment contact is similar to that described above, and will not be repeated here.

[0091] When the microprocessor 330 determines that the first DIP switch 501 or the second DIP switch 502 is in the second target state via the fourth or fifth electrical signal, it can determine that a preset function has been triggered. Furthermore, based on the parameter values ​​corresponding to the first state of the first DIP switch 501 and the second state of the second DIP switch 502 associated with the preset function, it can determine the parameter value of the target parameter. (Reference) Figure 6 If the second DIP switch 502 is in the state shown in A2, the target parameter I can be determined based on the parameter value 1.0 corresponding to the first state of the first DIP switch 501 and the parameter value 0.00 corresponding to the second state of the second DIP switch 502. r The final parameter value is 1.00I. n Substitute I directly n The actual value is sufficient.

[0092] In another possible embodiment, where the first and second adjustment mechanisms are composed of a third DIP switch 701, the third DIP switch 701 can correspond to a preset function in a fourth target state. For example, the fourth target state can be as follows: Figure 8 As shown in A3.

[0093] The preset function can be associated with the parameter value corresponding to the third state of the third DIP switch 701. Optionally, the parameter value corresponding to the third state of the third DIP switch 701 associated with the preset function can be indicated by a label, such as... Figure 8 As shown in the solid box, the preset function is associated with the parameter value 1.00 corresponding to the third state of the third DIP switch 701. For example, the preset function can be an alarm function.

[0094] The microprocessor 330 is used to determine the parameter value of the target parameter based on the parameter value corresponding to the third state when the third DIP switch 701 is determined to be in the fourth target state by the sixth electrical signal.

[0095] The principle of the signal conversion unit 320 for switching the on / off state of the adjustment contact is similar to that described above, and will not be repeated here.

[0096] When the microprocessor 330 determines that the third DIP switch 701 is in the fourth target state via the sixth electrical signal, it can determine that a preset function has been triggered. Furthermore, based on the parameter value corresponding to the third state of the third DIP switch 701 associated with the preset function, it can determine the parameter value of the target parameter. (Reference) Figure 8 If the third DIP switch 701 is in the state shown in A3, the target parameter I can be determined based on the parameter value 1.00 corresponding to the third state of the third DIP switch 701. r The final parameter value is 1.00I. n Substitute I directly n The actual value is sufficient.

[0097] It should be noted that the above preset functions can be set to one or more according to actual needs, including but not limited to alarm, remote setting (used to enable remote setting mode), and shutdown (used to disable the setting function of parameter setting component), etc.

[0098] By using the above method, while providing parameter setting functions through the parameter setting component, other functions can be integrated as needed, which helps to enrich the flexibility of parameter settings and the applicability of scenarios.

[0099] This disclosure also provides an electronic circuit breaker, such as Figure 10 As shown, this includes the parameter setting device provided in any embodiment of this disclosure. For example, the parameter setting panel of an electronic circuit breaker can be as follows: Figure 11 As shown, ALM corresponds to the alarm function mentioned earlier, and OFF corresponds to the shutdown function mentioned earlier.

[0100] Referring to the parameter setting device provided in this disclosure, parameters can be set as needed. Figure 11Any parameter in the settings allows for multi-granularity parameter settings, thereby improving the accuracy and flexibility of electronic circuit breakers.
