Due to the magnetic flux generated in the core 161, the first coil 162 may generate an induced current. The induced current of the first coil 162 may form magnetic flux in the opposite direction to the magnetic flux formed by the flow of the current to be measured in the core 161 . The core 161 may reduce or remove the magnetic flux inside the core 161 by the magnetic flux generated by the flow of the current to be measured and the magnetic flux generated by the first coil in the opposite direction. When the magnetic flux inside the core 161 is reduced, the current sensor 181 can increase accuracy associated with measuring current. According to an embodiment, the first coil 162 may reduce magnetic saturation by reducing residual magnetism inside the core 161 due to a negative feedback effect providing magnetic flux in the opposite direction, and may reduce magnetic saturation. The stability of the circuit can be improved. For example, power factor reduction or overheating due to magnetic saturation can be prevented.

According to one embodiment, the energy harvesting device 160 is generated by an electromagnetic induction phenomenon by an alternating current (eg, 60 Hz) flowing through the lines 12 and 13 of the fuse 11, and the first coil 162 The current transmitted through the current sensor 181 senses the current, and the current can also be supplied to the power supply unit 170 . Current passing through the power supply unit 170 may be supplied to the processor 120 , the memory 130 , or the communication module 190 and the sensor 180 .

According to an embodiment, the PMIC 171 of the power supply unit 170 may convert, amplify, distribute power, or perform a combination thereof according to the required power of components constituting the electronic device 100. The PMIC 171 may supply stable power to each component of the electronic device 100 . The PMIC 171 may supply stable power to each component of the electronic device 100 and store surplus power in the battery 176 . However, without being limited thereto, the PMIC 171 may pre-charge power based on the supplied power and supply power to components. For another example, the PMIC 171 performs charging when the charge amount of the battery is lower than a predetermined reference, and supplies stable power to components when the charge amount of the battery is higher than the predetermined reference, and then stores the remaining power. A battery 176 may be provided.

In the cut-out switch 1 in which the electronic device 100 is installed according to the above-described embodiment, the fuse ( Real-time monitoring of the status of 11) can be performed. The electronic device 100 is an external electronic device used by an external user (eg, a line manager, a control center manager) to determine whether the fuse 11 is normally operating by monitoring the current or voltage flowing through the fuse 11, Real-time monitoring can be provided by transmitting information about operating conditions (eg, normal, abnormal, or power outage conditions).

The electronic device 100 utilizes the energy harvesting device 160 to generate energy on its own without a separate power supply, and performs communication with an external electronic device, detection of information by a sensor module, and processing of information by a processor. By doing this, power consumption can be reduced, and the electronic device 100 can provide a method of utilizing wasted energy.

Referring to FIG. 4 , graphs A and B represent states of voltages applied to external lines (lines 12 or 13 in FIG. 2 ) or fuses 11 .

According to an embodiment, a processor (eg, the processor 120 of FIG. 1 ) may obtain voltage values such as graphs A and B through a current sensor (eg, the current sensor 181 of FIG. 1 ). there is.

The processor 120 may receive sensing data about current flowing into the current sensor 181 from the current sensor 181 . The processor 120 may calculate the current flowing through the external wire (eg, the lines 12 and 13 inside the fuse holder 10) based on the received sensing data of the current. For example, the processor 120 may store a relational expression or relational table capable of calculating the current flowing in an external wire based on the current flowing from the current sensor 181 in a memory. A relational expression may be a formula representing a relationship between an input and an output, and a relational table may not be a formula but a table in which calculated values according to input values are entered. Due to the current flowing in the external wire, a current may flow in a coil disposed around the external wire. The magnitude of the induced current of the coil 162 may be determined according to the number of windings wound around the core 161 . The conversion ratio between the induced current and the current flowing in the external line can be determined according to the number of windings. The memory 130 may store the number of windings of the coil 162, a relational expression, or a relational table necessary for the calculation operation. The processor 120 may calculate the magnitude of the current flowing through the external transmission line based on the relational expression stored in the memory 130 and the sensing data received from the current sensor 181 .

The processor 120 may calculate the voltage applied to the external wire based on the calculated current flowing through the external wire. The processor 120 may calculate a voltage applied to both ends of the external wire as a product of a resistance across both ends of the external wire and a current flowing through the external wire. The processor 120 may provide information such as graph A and/or graph B by inputting real-time information of the voltage calculated as described above.

Referring to graph A, in the case of a steady state (a1, a2, a3), it may be a case of having a voltage (V1 or less, V2 or more) in a specified range at a predetermined period. In the case of a normal state, the processor 120 may transmit a predetermined signal through a communication module (eg, the communication module 190 of FIG. 1 ).

Looking at graph A, in an abnormal state, when the voltage of the external transmission line is lower than the pre-specified range (b), when the voltage of the external transmission line is higher than the pre-specified range (c), and when no current flows through the external transmission line. (d) shows the voltage.

The predetermined range may be set to a normal range of about 12000V to 13800V when the voltage of the primary side of the transformer is 13200V as the rated voltage. As another example, the predetermined range may be approximately 6000V to 7000V when the voltage of the primary side of the transformer is 6600V as the rated voltage.

If the voltage of the external transmission line is lower than the predetermined range (b) or if the voltage of the external transmission line is higher than the predetermined range (c), the processor 120 analyzes the voltage waveform, and the analyzed waveform Patterns can be stored in memory. The processor 120 may store a pattern for a voltage drop state and a voltage rise state, and transmit signals such as graphs C and D to an external electronic device through a communication module (eg, the communication module 190 of FIG. 1 ). can transmit

When current does not flow through the external transmission line (d), the external transmission line may be cut (eg, the fuse 11 is disconnected), a transformer failure, or a cut-out switch may be operated. In addition, if current does not flow through an external transmission line, a blackout may occur in which power is not supplied to several households receiving power through a transformer.

Looking at the graph B, compared to the normal state (a), it includes a case showing a harmonic waveform (a-1) and a case showing a surge phenomenon (a-2).

The harmonic waveform may be a waveform obtained by combining a frequency component and a high frequency component formed based on the shape of the frequency in the normal state (a1, a2, and a3). In the case of a harmonic component, a signal received from the outside may be a waveform interfered with by noise.

The surge waveform represents a waveform instantaneously generated due to sudden external input or signal interference in the normal state (a1, a2, a3). In the case of surge waveforms and harmonics, the processor 120 may monitor through waveform analysis in order to filter the situation in the monitoring step in order to prevent deterioration of the quality of power provided to the home.

Referring to graph C, the processor 120 transmits a first signal including a value of 1 corresponding to the normal state to the external electronic device in a normal state, and transmits a value of 0 corresponding to the abnormal state to the external electronic device in an abnormal state. It is possible to transmit a second signal including. The method of representing the signal is not limited, and the first signal and the second signal may be interchanged.

Since the electronic device (e.g., the electronic device 100 of FIG. 1) operates without receiving a separate power supply from the outside, it processes information with bits using 0 and 1 to provide information in a minimum unit. , can be transmitted to an external electronic device.

Referring to graph D, the processor 120 may set a reference point at which a signal transmitted to an external electronic device in a normal state and a signal transmitted to an external electronic device in an abnormal state are transmitted differently.

In a normal state, the processor 120 may supply the first signal to the external electronic device from the first time point t1 to the first cycle T. In the abnormal state, the second signal may be supplied every time equal to T, which is the second period, from the second time point t2. For example, the processor 120 may transmit a first transmission signal to an external electronic device at t1, t1+T, and t1+2T to transmit a steady state signal in the a1 state of graph A. . The processor 120 may transmit the second transmission signal to the external electronic device at t2+2T and t2+3T to transmit the abnormal state signal in the b state of graph A.

The processor 120 may change the size of the second cycle, which is the signal transmission cycle, to T/4 in a power failure state among abnormal states. The size of the second period may be different from that of the first period. The size of the second period may be determined according to the type of abnormal state. For example, if the magnitude of the voltage applied to the external transmission line is smaller or larger than the reference range, it may be a temporary phenomenon, so the processor 120, through the communication module 190, sends a second signal indicating that it is abnormal, It can be transmitted to an external electronic device for every T, which is the same second period as the first period.

According to an embodiment, the processor 120, among the abnormal conditions, may cause a disruption in the supply and demand of power supplied to a plurality of households, and therefore urgently needs to be restored, so that the second period is shorter than the first period. The second signal may be transmitted to the external electronic device every cycle of T/4.

According to an embodiment, the processor 120 may include an identifier corresponding to the electronic device in the first signal and the second signal. For example, in graph C, the processor 120 may transmit a signal corresponding to an identifier when starting signal transmission, and then transmit a signal corresponding to a state of an external transmission line. For another example, in the graph D, the processor 120 may transmit the first signal and the second signal as signals representing identifiers. For example, if the identifier of the electronic device 100 is 10, the first signal and the second signal may be 1010, which is a binary number representing 10. In a normal state, the processor 120 may transmit signals of 1,0,1,0 corresponding to the identifier of the electronic device 100 to the external electronic device at time points t1+T and t1+2T. In an abnormal state, the processor 120 may transmit signals of 1,0,1,0 corresponding to the identifier of the electronic device 100 to the external electronic device at time points t2+2T and t2+3T. . The processor 120 may transmit signals of 1, 0, 1, 0 corresponding to the identifier of the electronic device 100 to the external electronic device at a cycle of T/4 in a power failure state among abnormal states.

According to an embodiment, the electronic device 100 may transmit the first signal or the second signal transmitted to the outside to the external electronic device using different frequency bands. For example, the first signal may be transmitted in a first frequency band and the second signal may be transmitted in a second frequency band to distinguish the first signal and the second signal. Since the first signal and the second signal include only the identifier of the electronic device 100 and are transmitted in different frequency bands, the amount of signal transmission and power consumption can be reduced, and only the current of the energy harvesting device 160 , the electronic device 100 can be driven.

According to the above-described embodiment, the electronic device 100 can reduce power consumption by providing a method for transmitting various states of an external wire (eg, a wire or a fuse in a fuse holder) with a small amount of data. In addition, in a power outage state, the electronic device 100 may transmit a signal at a short period to notify an urgency while reducing omission of a signal transmitted to an external line manager or control center.

5 illustratively illustrates a period D according to detection of movement of an external wire by an electronic device, according to an embodiment.

According to an embodiment, a processor (eg, the processor 120 of FIG. 1 ) may obtain an acceleration value as shown in graph A through an acceleration sensor (eg, the acceleration sensor 182 of FIG. 1 ). Graph A is expressed as the processor 120 obtaining an acceleration value through the acceleration sensor 182, but is not limited thereto, and the processor 120 obtains displacement values of the x, y, and z axes to form a graph. can

The processor 120 may obtain the amount of change in acceleration applied to the electronic device 100 from the acceleration sensor 182 . Looking at graph a, it can be seen that at time point td, a force is applied in the -a direction by an external impact. For example, as a fuse (eg, fuse 11 of FIG. 2 ) disposed in a fuse holder (eg, fuse holder 10 of FIG. 2 ) to which the electronic device 100 is attached is blown, the fuse holder 10 ) can act as a downward force. Accordingly, the fuse holder 10 has negative acceleration and can move toward the bottom.

Referring to graph (a), the electronic device 100 attached to the fuse holder 10 is in a transient state in which the magnitude of the acceleration gradually decreases after having the maximum magnitude of negative acceleration after the time point td. With , after a certain period of time, it can enter a steady state in which the acceleration is zero. For example, the fuse holder 10 receives a downward force as much as the gravitational acceleration as the fuse 11 blows, but a lower bracket connected to the lower part 41 of the insulator (eg, the insulator 40 in FIG. 2 ). By (20), rotational motion or pendulum motion can be performed. Since the applied force gradually decreases due to the frictional force between the fuse holder 10, the lower bracket 20, and the lower connection member 30, the acceleration of the electronic device 100 or the fuse holder 10 converges to zero. can

Before time td, the processor 120 does not determine that the fuse 11 is blown because there is no change in acceleration or there is a change in acceleration below the threshold value, and the first signal indicating that the fuse 11 is in a normal state is sent to an external electronic device, can transmit The processor 120 may determine that the fuse 11 is blown when an acceleration equal to or greater than the threshold value is applied at time td, and may transmit a second signal distinct from the first signal to the external electronic device.

Referring to graph (b), the processor 120 may transmit a second signal instructing that the fuse 11 is blown from the time point td through the detection of an external impact. The first signal may be a signal transmitted before time td. The first signal may be 0 indicating a normal state, and the second signal may be 1 indicating an abnormal state. However, it is not limited thereto, and the first signal and the second signal may be interchanged.

Referring to graph (c), the processor 120 transmits the first signal to the external electronic device at a period T1 through the communication module 190 before time td, and transmits the second signal to the communication module after time Td. Through 190, it can be transmitted to an external electronic device at period T2. Since the first signal and the second signal are transmitted at different cycles, the external electronic device can determine situations indicated by the first signal and the second signal based on the cycles. According to an embodiment, the processor 120 may transmit the first signal and the second signal at different cycles while including another signal indicating a state. For example, the first signal is a signal including 0 indicating normal is transmitted to the external electronic device in a first period T1, and the second signal is a signal including 1 indicating abnormality is transmitted to the external electronic device in a second period T2. can be sent to

Referring to graph (d), the processor 120 transmits a first signal indicating that the electronic device 100 or the fuse holder 10 is normal before time td through the communication module 190 at a period T from time t1. It can be sent out every time. After time td, the processor 120 may transmit a second signal indicating that the electronic device 100 or the fuse holder 10 is abnormal through the communication module 190 to the outside every period T from time t2. .

According to the above-described embodiment, the electronic device 100 can quickly identify the blown fuse 11 and immediately notify the external electronic device, thereby increasing the efficiency of managing a plurality of transformers. The electronic device 100 can reduce the amount of data transmission to the external electronic device, thereby reducing power consumption due to data transmission.

6 is a flowchart illustrating a method of providing a monitoring result of an external line to an external electronic device, according to an embodiment.

Referring to FIG. 6 , in operation 610, a processor (eg, the processor 120 of FIG. 1 ) may obtain current and voltage values of an external line. For example, the processor 120, through the sensor 180, an induced current generated in a coil (eg, coil 162 of FIG. 1) by an alternating current flowing in an external line (eg, a line in a fuse holder) can detect Since the core 161 surrounds the external line, an induced current may be generated in the coil 162 by a current flowing through the external line. Based on the sensed induced current, the processor 120 may calculate a current value flowing through an external line through a turns ratio of a coil 162 wound around a core (eg, the core 161 of FIG. 1 ). According to an embodiment, the processor 120 may calculate the voltage applied to both ends of the external line in consideration of the load of the external line based on the calculated current value.

In operation 620, the processor 120 may determine whether the obtained current and voltage values are within a predetermined range. When obtaining the current and/or voltage values, the processor 120 calls a predetermined range of current and/or voltage stored in a memory (eg, the memory 130 of FIG. 1 ) to obtain the obtained current and/or voltage. values can be compared. For example, if the range of voltage is a household voltage of 220V, the range of current flowing in an external transmission line may be 12,000V to 13,800V.

In operation 630, the processor 120 may determine whether current and voltage values are within a pre-specified range and transmit voltage and current monitoring signals to an external electronic device. For example, if the current and voltage values are within a pre-specified range, the processor 120 may transmit a first signal indicating a normal state to the external electronic device, and if the current and voltage values exceed a pre-specified range, the processor 120 may indicate an abnormal state. A second signal for instructing may be transmitted to an external electronic device.

Hereinafter, in FIG. 7 , a method of determining the state of the external line related to operation 630 based on the flow of current among the methods of determining the state of the external line will be described.

According to the above-described embodiment, the electronic device 100 acquires the current and/or voltage flowing in the external line through the current sensor, determines the state of the external line through this, and transfers the state of the external line to the external electronic device. By notifying, a line manager or control center manager using an external electronic device can monitor the state of an external line in real time without going to the field of a pole-mounted transformer and checking the state of a fuse holder.

7 is a flowchart illustrating a method of determining a state of an external line, according to an embodiment.

Referring to FIG. 7 , in order to determine the state of the external line, in operation 710, the processor 120 may detect the flow of current flowing through the external line.

For example, the processor 120, through the sensor 180, an induced current generated in a coil (eg, coil 162 of FIG. 1) by an alternating current flowing in an external line (eg, a line in a fuse holder) can detect Based on the sensed induced current, the processor 120 may calculate a current value flowing through an external line through a turns ratio of a coil 162 wound around a core (eg, the core 161 of FIG. 1 ).

In operation 720, the processor 120 may determine whether the current flowing through the external line is zero. For example, if the current applied to the current sensor (eg, the current sensor 181 of FIG. 1 ) is 0, the processor 120 may determine that no current flows through the external line. However, it is not limited thereto. Even when the current flowing through the external line is not 0, the current flowing into the current sensor 181 may be 0. For example, when direct current flows through an external line, there is no change in current, and the current flowing through a coil (eg, coil 162 of FIG. 1 ) may be zero. Since alternating current is supplied to the pole-type transformer, the processor 120 may determine that there is no current flowing in the external line when the current flowing into the current sensor 181 is 0.

When the current flowing through the external line is 0, the processor 120 may transmit a signal indicating a power failure state to the external electronic device in operation 730 . Based on the fact that the current flowing into the current sensor 181 is 0 and it is determined that there is no current flowing in the external line, the processor 120 sends a signal indicating that there is no current flowing in the external line, that is, as an external electronic device. Electricity supplied through an external line may transmit a signal indicating a power outage state.

According to an embodiment, the electronic device 100 may transmit and receive signals to and from an external electronic device even in a power failure state. For example, the electronic device 100 stores power in a battery through the energy harvesting device 160, and when a current induced to the electronic device 100 is not generated, the electronic device 100 stores power in advance. The battery may drive the processor 120, the memory 130, and/or the communication module 190 of the electronic device 100 to transmit a power failure signal to an external electronic device.

If the current flowing through the external line is not 0, the processor 120 may determine, in operation 740, whether the value of the current flowing through the external line is within a predetermined range. The processor 120 may calculate a value of the current flowing through the external line through the current sensor 181 and determine whether the value of the current flows within a predetermined range or an appropriate allowable current based on the calculated current value.

When the magnitude of the value of the current flowing through the external line is out of a predetermined range, the processor 120 may transmit a signal indicating an abnormal state to the external electronic device in operation 750, and the processor 120 may transmit a signal indicating an abnormal state to the external electronic device. If the magnitude of the value of the current is within a predetermined range, in operation 760, a signal indicating a normal state may be transmitted to the external electronic device.

The processor 120 may transmit a first signal indicating a normal state or a second signal indicating an abnormal state to an external electronic device based on the measured current value. The first signal, the signal indicating the normal operation of the external transmission line, and the second signal, the signal indicating the abnormal operation of the external transmission line, may be digital signals represented by bits.

According to one embodiment, the first signal is transmitted to the external electronic device in a first period through the communication module 190, and the second signal is distinguished from the first period through the communication module 190. It may be transmitted to an external electronic device in a second cycle. For example, the first period may be longer than the second period. A signal indicating an abnormal state is provided at a fast cycle and can be quickly transmitted to a line manager.

According to an embodiment, the first signal is transmitted to the external electronic device at a predetermined period from a first time point specified in advance through the communication module 190, and the second signal is transmitted through the communication module 190. , may be transmitted to an external electronic device at a predetermined period from a second time point distinct from the first time point. The first time point or the second time point may mean a reference time point at which the first signal or the second signal is provided. For example, the first signal may be transmitted to the external electronic device at a period of 10 seconds from 1 second as a first time point, and the second signal may be transmitted to the external electronic device at a period of 10 seconds from 3 seconds as a second time point. The processor 120 may transmit a signal indicating normality to the external electronic device at intervals of 10 seconds, such as 1, 11, 21, 31, and 41 sec. When the non-operational state of the external transmission line is identified, the processor 120 checks the identification time, and if the checked time is 49 seconds, the second signal can be transmitted in a 10-second period starting from 53 seconds. For example, the processor 120 has 53, 63, 73, 83, 93??. The second signal may be transmitted to the external electronic device at intervals of 10 seconds, such as seconds. The electronic device 100 may further include a timer for managing a period and timing. The first signal and the second signal may include an identifier corresponding to the electronic device 100 . For example, since a signal can be distinguished according to a time point at which the signal is provided, the first signal and the second signal themselves may be signals representing identifiers.

As described above, when the electronic device 100 transmits data to an external electronic device, the amount of data is reduced, and based on power generated by itself or stored in a battery without a separate power supply, the electronic device 100 communicates with the external electronic device. Communication can be performed, even in an emergency, by providing monitoring of the state of an external transmission line, continuous monitoring information can be provided to a wire manager or control center.

8 is a flowchart illustrating a method of providing a motion result of an external line to an external electronic device, according to an embodiment.

Referring to FIG. 8 , in operation 810, the processor 120 may detect movement of an external line. The processor 120 may detect a movement of an external line or an impact applied to the external line through the acceleration sensor 17 of the electronic device 100 . The processor 120 may detect a displacement of the external line in the x, y, and z-axis directions, or may detect a change in acceleration of the external line in the x, y, and z-axis directions. The processor 120 may detect a movement of an external line (eg, a fuse holder) to which the electronic device 100 is attached by detecting displacement. The processor 120 may detect a change in acceleration and detect a degree of impact applied to an external line to which the electronic device 100 is attached.

In operation 820, the processor 120 may transmit a signal related to the abnormality of the external line to the external electronic device based on the movement of the external line.

Based on the detection of the movement of the external line, the processor 120 may transmit a second signal indicating an abnormal operation of the external line to the external electronic device through the communication module 190 .

For example, the processor 120, through an acceleration sensor or a displacement sensor, if the movement or displacement of the external transmission line is within a predetermined range, the external electronic device through the communication module, if the movement of the external transmission line is normal A first signal instructing an operation may be transmitted. When the motion or displacement of the external transmission line is out of a predetermined range through an acceleration sensor or a displacement sensor, the processor 120 transmits the normal operation of the external transmission line through the communication module 190 to an external electronic device. It is possible to transmit a first signal indicating.

The processor 120 transmits a first signal instructing the normal operation of the external line or a second signal instructing the abnormal operation of the external line to the external electronic device through the communication module, based on the detection of the impact of the external line. can send

For example, the processor 120, through the acceleration sensor, if the impact amount of the external line is within a pre-specified range, a first step instructing the normal operation of the external line through the communication module to an external electronic device When the signal is transmitted and the amount of impact applied to the external line is out of a predetermined range, the processor 120 may transmit a second signal indicating an abnormal operation of the external line to the external electronic device.

According to an embodiment, the electronic device 100 detects, through an acceleration sensor, when a fuse is disconnected due to an external impact or an impact such as a blown fuse in the fuse holder, and the external electronic device (eg, server or wire management) Based on the result detected by the terminal), the state of the wire or fuse can be estimated and transmitted. After transmitting the detection result to the external electronic device, when the current flow in the external transmission line is sensed through the current sensor, the processor 120 operates normally, based on the magnitude of the current flowing in the current sensor. can determine whether
