Method and device for copying circuit breaker settings

[0001] The present invention relates to a method and device for copying the setting value of a circuit breaker.

[0002] Air circuit breakers (ACBs) and molded case circuit breakers (MCCBs) are devices that protect circuits from abnormal currents on the load side. Circuit breaker trip testers are used to verify the operation of these circuit breakers.

[0003] Conventional circuit breaker trip testers tested the current trip function by directly applying an analog signal to the current channel. However, with advancements in communications, current, voltage, and frequency data are now transmitted to the circuit breaker trip tester for testing. However, in smart factories, where multiple circuit breakers are installed, the need to manually configure settings, such as relay values, for each circuit breaker presents a challenge. Furthermore, this manual configuration can lead to human error.

[0004] Therefore, there is an emerging need for technology development that can more easily set settings for multiple circuit breakers.

[0005] Embodiments of the present invention for solving these conventional problems provide a method and device for copying setting values ​​of circuit breakers, which can more easily set setting values ​​of multiple circuit breakers by reading the setting value of a first circuit breaker and applying the setting value to at least one second circuit breaker.

[0006] In order to solve the above technical problem, a method for copying a setting value of a circuit breaker by executing an operation program recorded in a memory by a control unit of an electronic device according to an embodiment of the present invention may include the steps of: receiving a first signal requesting a read operation; reading a setting value of a first circuit breaker in response to the first signal; storing the setting value in the memory; receiving a second signal requesting a write operation; and writing the setting value to a second circuit breaker that will use the same setting value as the setting value of the first circuit breaker in response to the second signal.

[0007] In one embodiment of the present invention, the method further includes a step of checking information of the first circuit breaker; and the information of the first circuit breaker can check whether the setting value can be written to the second circuit breaker.

[0008] In one embodiment of the present invention, the step of checking information of the second circuit breaker is further included, and the information of the second circuit breaker can check whether the setting value can be written to the second circuit breaker.

[0009] In one embodiment of the present invention, the method may further include: a step of confirming information of the second circuit breaker; and a step of determining whether the setting value can be used in the second circuit breaker based on information of the first circuit breaker and information of the second circuit breaker.

[0010] In one embodiment of the present invention, the step of outputting a write-unable message when the setting value cannot be written to the second circuit breaker may be further included.

[0011] In one embodiment of the present invention, the information of the first circuit breaker and the information of the second circuit breaker include information regarding versions, and when the version of the first circuit breaker is equal to or lower than the version of the second circuit breaker, the setting value is determined to be usable for the second circuit breaker, and the setting value of the higher version circuit breaker may include all of the same relay element information data as the setting value information of the lower version circuit breaker.

[0012] In one embodiment of the present invention, the information of the first circuit breaker and the information of the second circuit breaker include information regarding versions, and if the version of the first circuit breaker is higher than the version of the second circuit breaker, the setting value is determined to be unusable for the second circuit breaker, and the setting value of the lower version circuit breaker may not include at least one relay element data item among the setting values ​​of the higher version circuit breaker.

[0013] In one embodiment of the present invention, the memory may further include a step of determining at least one of the built-in memory and the external memory as a storage medium for storing the setting value, wherein the memory includes a built-in memory and an external memory.

[0014] In one embodiment of the present invention, the setting value may include relay element data of the first circuit breaker.

[0015] In one embodiment of the present invention, the setting value may further include factory setting data, operating data, and calibration data of the first circuit breaker.

[0016] In one embodiment of the present invention, the method further includes a step of determining whether the first signal is a signal for testing a trip function of the second circuit breaker or a signal for replacing the first circuit breaker with the second circuit breaker; and if the first signal is a signal for testing a trip function of the second circuit breaker, the setting value may include relay element data of the first circuit breaker, and if the first signal is a signal for replacing the first circuit breaker with the second circuit breaker, the setting value may include relay element data, factory setting data, operation data, and calibration data of the first circuit breaker.

[0017] In addition, in order to solve the above technical problem, a device for copying a setting value of a circuit breaker according to an embodiment of the present invention includes a memory in which an operation program is recorded; a control unit for executing the operation program; and a communication unit capable of communicating with a first circuit breaker and a second circuit breaker; wherein the control unit receives a first signal requesting a read operation, reads the setting value of the first circuit breaker in response to the first signal, stores the setting value in the memory, and receives a second signal requesting a write operation, and writes the setting value to the second circuit breaker that will use the same setting value as the setting value of the first circuit breaker in response to the second signal.

[0018] In one embodiment of the present invention, the present invention may further include an input unit that generates at least one of the first signal and the second signal.

[0019] As described above, the method and device for copying the setting values ​​of a circuit breaker according to the present invention can solve the problem of having to manually set the setting values ​​of multiple circuit breakers by reading the setting values ​​of a first circuit breaker and applying the corresponding setting values ​​to at least one second circuit breaker, and can have the effect of more accurately confirming the test results of the trip function by eliminating human error that may occur when setting the setting values.

[0023] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The detailed description set forth below, together with the accompanying drawings, is intended to explain exemplary embodiments of the present invention and is not intended to represent the only embodiments in which the present invention may be practiced. In the drawings, portions irrelevant to the description may be omitted for clarity in describing the present invention, and the same reference numerals may be used throughout the specification for identical or similar components.

[0024]

[0025] FIG. 1 is a block diagram showing the main configuration of an electronic device for copying the setting value of a circuit breaker according to an embodiment of the present invention.

[0026] Referring to FIG. 1, an electronic device (100) according to the present invention may include a communication unit (110), an input unit (120), a display unit (130), a memory (140), and a control unit (150). In this case, the electronic device (100) refers to a circuit breaker trip tester for verifying the operation of a circuit breaker.

[0027] The communication unit (110) performs communication with a plurality of circuit breakers (not shown). To this end, the communication unit (110) can perform wired communication such as UART (universal asynchronous receiver / transmitter) with the plurality of circuit breakers, and can perform wireless communication such as BLE (Bluetooth low energy), Bluetooth, and NFC (near field communication).

[0028] The communication unit (110) can read the setting value set in the first circuit breaker through communication with the first circuit breaker and transmit it to the control unit (150). The communication unit (110) can transmit the setting value transmitted from the control unit (150) to at least one second circuit breaker so that the setting value can be written to at least one second circuit breaker. At this time, the first circuit breaker may refer to a circuit breaker in which the setting value is normally set, and the plurality of second circuit breakers may refer to circuit breaker that copies and uses the setting value set in the first circuit breaker as is.

[0029] The input unit (120) generates input data in response to input from a user of the electronic device (100). The input unit (120) includes at least one input means. For this purpose, the input unit (120) may include a keyboard, a mouse, a keypad, a dome switch, a touch panel, touch keys, and buttons.

[0030] The display unit (130) outputs output data according to the operation of the electronic device (100). To this end, the display unit (130) may include a liquid crystal display (LCD), a light emitting diode (LED) display, an organic light emitting diode (OLED) display, a micro electro mechanical systems (MEMS) display, and an electronic paper display. The display unit (130) may be implemented as a touch screen by being combined with the input unit (120).

[0031] The memory (140) stores the operating programs of the electronic device (100). In particular, the memory (140) may include built-in memory such as RAM (random access memory) and external memory such as SD (secure digital) card that is inserted into the electronic device (100) and performs a memory function.

[0032] When a read signal for reading the setting value of the first circuit breaker is received from the input unit (120), the control unit (150) checks the storage medium for storing the setting value among the storage media included in the memory (140). More specifically, the memory (140) may include a built-in memory such as a RAM and an external memory such as an SD card that is inserted into the electronic device (100) and performs a memory function. The control unit (150) may check either the built-in memory or the external memory as the storage medium for storing the setting value.

[0033] The control unit (150) verifies basic information of the first circuit breaker. At this time, the basic information may include serial information of the first circuit breaker, model name information, manufacturer information, and the type of the first circuit breaker. The type of the first circuit breaker may include a supreme type (S type), a power type (P type), and an ampere type (A type).

[0034] The control unit (150) can read the relay element data, which is a setting value set in the first circuit breaker, if the read signal is a read signal for testing the trip function of at least one second circuit breaker. At this time, the type of relay element data read by the control unit (150) varies depending on the type of the first circuit breaker. For example, the relay element data read from the S-type first circuit breaker can include 35 types of data, the relay element data read from the P-type first circuit breaker can include 27 types of data, and the relay element data read from the A-type first circuit breaker can include 6 types of data.

[0035] In addition, if the read signal is a read signal for replacing the first circuit breaker with another circuit breaker for reasons such as after-sales service (AS), the control unit (150) can read the relay element data, factory setting data, operating data, and calibration data, which are the setting values ​​set in the first circuit breaker. At this time, the factory setting data, operating data, and calibration data may be data related to the site where the first circuit breaker is installed.

[0036] Factory setting data may include NFC presence, Poles, IEC / UL select, Frame size, ampere frame, rating plug[A], maximum CB (circuit breaker) mechanical off count, maximum CB electrical off count, maximum contact wear, short circuit current and option settings.

[0037] Operational data may include device description nave, network set, rated voltage[V], current direction, address, baud rate, DO(digital output) setting, demand time[minutes], L / R (local / remote) control, frequency, language, over temperature trip, group control, PF(power factor) display, under PF alarm setting value, over PF alarm setting value, etc.

[0038] The control unit (150) stores the setting values ​​read from the first circuit breaker in the built-in memory or external memory. At this time, the control unit (150) can store only the relay element data read from the first circuit breaker, and can store all of the relay element data, factory setting data, operating data, and calibration data.

[0039] In this way, after reading the setting value from the first circuit breaker, the control unit (150) receives a write signal from the input unit (120) to write the setting value of the first circuit breaker stored in the memory (140) to at least one second circuit breaker. At this time, if the electronic device (100) is connected to at least one second circuit breaker via wireless communication, the setting value can be transmitted to all connected second circuit breakers sequentially or simultaneously. In addition, if the electronic device (100) is connected to the second circuit breaker via a wire, the user can directly change the connection with the second circuit breaker and transmit the setting value to the second circuit breaker.

[0040] When a write signal for writing a setting value to at least one second circuit breaker is received from the input unit (120), the control unit (150) checks basic information of at least one second circuit breaker. More specifically, the basic information may include serial information, model name information, manufacturer information, and the type of the second circuit breaker connected to the electronic device (100). The type of the second circuit breaker may include a supreme type (S type), a power type (P type), and an ampere type (A type).

[0041] The control unit (150) checks the storage medium in which the setting values ​​are stored and calls the setting values ​​stored in the storage medium. The control unit (150) checks whether the called setting values ​​can be written to at least one second circuit breaker.

[0042] More specifically, if the type of the second circuit breaker is a circuit breaker of the same or lower version than the type of the first circuit breaker, the control unit (150) can determine that it is possible to write the set value to the second circuit breaker, and if the type of the second circuit breaker is a circuit breaker of a higher version than the type of the first circuit breaker, the control unit (150) can determine that it is impossible to write the set value to the second circuit breaker. For example, if the type of the second circuit breaker is any one of S-type, P-type, and A-type, and the type of the first circuit breaker is S-type, the control unit (150) determines that it is possible to write the set value to the second circuit breaker. Conversely, if the type of the second circuit breaker is S-type, and the type of the first circuit breaker is P-type or A-type, the control unit (150) determines that it is impossible to write the set value to the second circuit breaker.

[0043] The control unit (150) is capable of writing a set value to at least one second circuit breaker, and if the write signal is a write signal for testing the trip function of at least one second circuit breaker, the control unit (110) controls the communication unit (110) to cause the second circuit breaker to write the set value, e.g., relay element data, and transmit the set value to at least one second circuit breaker.

[0044] In addition, the control unit (150) can write the set value to at least one second circuit breaker, and if the write signal is a write signal for replacing the first circuit breaker with another circuit breaker due to AS of the first circuit breaker, etc., the communication unit (110) can be controlled so that the second circuit breaker writes the set value, for example, factory setting data, operating data, calibration data, and relay element data, and transmits the set value to at least one second circuit breaker. In this way, when temporarily or completely replacing the first circuit breaker with another circuit breaker, the set value of the first circuit breaker, that is, the relay element data, factory setting data, operating data, and calibration data, are copied as is to the other circuit breaker, thereby making it possible to more easily set the set value of the other circuit breaker.

[0045] Conversely, if it is impossible to write the setting value to at least one second circuit breaker, the control unit (150) generates a message indicating that the types of the first and second circuit breakers are different and copying of the setting value is impossible, and displays the message on the display unit (130).

[0046]

[0047] FIG. 2 is a flowchart for explaining a method for reading a setting value of a circuit breaker according to an embodiment of the present invention.

[0048] Referring to FIG. 2, in step 201, the control unit (150) checks whether a read signal for reading the setting value of the first circuit breaker is received from the input unit (120). If the read signal is received in step 201, the control unit (150) performs step 203, and if the read signal is not received, the control unit (150) can wait for reception of the read signal.

[0049] In step 203, the control unit (150) identifies a storage medium for storing the setting value among the storage media included in the memory (140). More specifically, the memory (140) may include built-in memory such as RAM and external memory such as an SD card that is inserted into the electronic device (100) and performs a memory function. The control unit (150) may identify either the built-in memory or the external memory as a storage medium for storing the setting value.

[0050] In step 205, the control unit (150) checks the basic information of the first circuit breaker. At this time, the basic information of the first circuit breaker may include serial information, model name information, manufacturer information, and the type of the first circuit breaker connected to the electronic device (100). The type of the first circuit breaker may include a supreme type (S type), a power type (P type), and an ampere type (A type).

[0051] In step 207, the control unit (150) can read the setting value of the first circuit breaker. More specifically, if the read signal received in step 201 is a read signal for testing the trip function of at least one second circuit breaker, the control unit (150) can read the relay element data, which is the setting value set in the first circuit breaker. At this time, the types of the relay element data are as shown in Table 1 below, and the types of data read by the control unit (150) differ depending on the type of the first circuit breaker. The data read from the S-type first circuit breaker may include all the relay element data listed in Table 1. In addition, the data read from the P-type and A-type first circuit breakers may include only the relay element data indicated by O in Table 1.

[0053] In addition, if the read signal in step 201 is a read signal for replacing the first circuit breaker with another circuit breaker for reasons such as after-sales service, the control unit (150) can read relay element data, factory setting data, operating data, and calibration data, which are the setting values ​​set for the first circuit breaker. At this time, the factory setting data, operating data, and calibration data may be data related to the site where the first circuit breaker is installed. The factory setting data may include NFC presence or absence, Poles, IEC / UL select, Frame size, ampere frame, rating plug[A], maximum CB mechanical off count, maximum CB electrical off count, maximum contact wear, short-circuit current, and option settings, etc. The operating data may include device description nave, network set, rated voltage[V], current direction, address, baud rate, DO setting, demand time[minute], L / R control, frequency, language, over temperature trip, group control, PF display, under PF alarm setting value, over PF alarm setting value, etc.

[0054] In step 209, the control unit (150) stores the setting value read in step 207 in the storage medium confirmed in step 203. At this time, the control unit (150) can store only the relay element data read from the first circuit breaker, and can store all of the relay element data, factory setting data, operation data, and calibration data.

[0055]

[0056] FIG. 3 is a flowchart illustrating a method of writing a setting value to a circuit breaker according to an embodiment of the present invention.

[0057] Referring to FIG. 3, in step 301, the control unit (150) checks whether a write signal is received from the input unit (120) to write the setting value of the first circuit breaker stored in the memory (140) to at least one second circuit breaker. If the write signal is received in step 301, the control unit (150) may perform step 303, and if the write signal is not received, the control unit may wait for the receipt of the write signal.

[0058] In step 303, the control unit (150) checks the basic information of at least one second circuit breaker for writing the setting value. More specifically, the basic information may include information such as serial information, model name information, manufacturer information, and the type of the second circuit breaker connected to the electronic device (100). The types of the second circuit breaker may include supreme type (S type), power type (P type), and ampere type (A type). At this time, when the electronic device (100) is connected to one second circuit breaker through wired communication, the control unit (150) may receive and check the basic information from the connected second circuit breaker. When the electronic device (100) is connected to at least one second circuit breaker through wireless communication, the control unit (150) may receive and check the basic information from at least one connected second circuit breaker.

[0059] In step 305, the control unit (150) checks the storage medium in which the setting value is stored, and in step 307, the control unit (150) calls the setting value stored in the storage medium. In step 309, the control unit (150) checks whether the called setting value can be written to at least one second circuit breaker.

[0060] More specifically, if the type of the second circuit breaker is a circuit breaker of the same or lower version than the type of the first circuit breaker, the control unit (150) can determine that it is possible to write the set value to the second circuit breaker, and if the type of the second circuit breaker is a circuit breaker of a higher version than the type of the first circuit breaker, the control unit (150) can determine that it is impossible to write the set value to the second circuit breaker. For example, if the type of the second circuit breaker is any one of S-type, P-type, and A-type, and the type of the first circuit breaker is S-type, the control unit (150) determines that it is possible to write the set value to the second circuit breaker. Conversely, if the type of the second circuit breaker is S-type, and the type of the first circuit breaker is P-type or A-type, the control unit (150) determines that it is impossible to write the set value to the second circuit breaker.

[0061] As a result of the verification in step 309, if it is possible to write the set value to at least one second circuit breaker, the control unit (150) performs step 311. In step 311, if the write signal received in step 301 is a write signal for testing the trip function of at least one second circuit breaker, the control unit (150) controls the communication unit (110) to cause the second circuit breaker to write the set value, e.g., relay element data, and transmit the set value to at least one second circuit breaker.

[0062] In addition, if the write signal received in step 301 is a write signal for replacing the first circuit breaker with another circuit breaker due to reasons such as AS of the first circuit breaker, the control unit (150) can transmit the factory setting data, operating data, and calibration data, which are the setting values ​​set in the first circuit breaker, together with the relay element data, to at least one second circuit breaker. In this way, when temporarily or completely replacing the first circuit breaker with another circuit breaker, the relay element data, factory setting data, operating data, and calibration data, which are the setting values ​​of the first circuit breaker, are copied as they are to the other circuit breaker, thereby making it possible to more easily set the setting values ​​of the other circuit breaker.

[0063] Conversely, if the verification result of step 309 indicates that it is impossible to write the set value to at least one second circuit breaker, the control unit (150) performs step 313. In step 313, the control unit (150) generates a message indicating that copying of the set value is impossible because the types of the first and second circuit breakers are different, and displays the message on the display unit (130).

[0064] In addition, when the storage medium is an internal memory, FIGS. 2 and 3 can be performed sequentially, and when the storage medium is an external memory, FIGS. 2 and 3 can be performed with a time difference.
