In general, a distribution board installed in a customer is also referred to as an electric distribution board or an electric distribution board. In a conventional distribution board, only an electric breaker is provided to cut off electric power from a power source when an overcurrent or a leakage current flows.

Such a conventional distribution panel is used for the purpose of shunting the electric wire, and it is only possible to perform a simple operation in which the electric breaker is turned on or off, so that the abnormality (malfunction or minor movement) In addition, since there is no display function, it is impossible to know the overload state or the short circuit state of the load side line and the function of predicting or notifying the load side line is not provided. none. In addition, the conventional distribution panel does not have the function of transmitting the information about the operation of the electric breaker, so that it is impossible to monitor whether or not the safety operation is performed at a remote place.

Of course, an intelligent distribution board having various functions has been proposed by supplementing the distribution panel provided with such a simple electric circuit breaker, through the registered patent No. 10-0896894 and the registered patent No. 10-1220773.

However, the conventional circuit breaker of the intelligent power distribution panel has a fixed trip current and trip time, and its function is simple. Therefore, it is difficult to cope appropriately with a rapid response in various situations requiring urgency.

Furthermore, if the earth leakage breaker fails to work properly, there is a serious problem of human accidents and fire accidents.

Accordingly, it is an object of the present invention to provide an artificial intelligent distribution board for controlling load power so as to monitor the load state in real time and reduce the maximum load in addition to the power distribution function .

In addition, the present invention provides an artificial intelligent distribution board that allows a user to check energy usage and charges in real time including power quality information at a glance, and to transmit the information to a moving administrator using an internet network when a problem occurs in a power system The purpose is to provide.

In order to solve such a technical problem,

The calculation processing means stores the waveform of the leakage current measured by the zero-current transformer (ZCT) of the load monitoring means for each set time in the memory. If the waveform detected in the zero-current transformer (ZCT) differs from the waveform stored in the memory It is determined that the leakage current is abnormal, and the individual load switch is interrupted twice and the closing control is repeated at the set time unit, and the leakage current newly detected again by the zero-current transformer ZCT is determined.

At this time, the arithmetic processing means determines whether the leakage current newly detected in the ZCT is normal or not. If the abnormality signal is abnormal, the individual load switch is cut off and the leakage current abnormality And outputs an alarm relating to the signal.

The operation processing means transmits the leakage current abnormality signal to a power management server at a remote site, and the power management server transmits a leakage current abnormality signal message to the administrator terminal and the user terminal of the corresponding customer.

Then, the individual load switch is interrupted twice and the closing control is repeated in the set time unit. ) Of the load current to be newly detected.

At this time, if the load current is normal, the arithmetic processing means normally restores the individual load switch, and when the abnormal signal is continuously detected, the individual load switch is cut off and the alarm is outputted through the buzzer.

The operation processing unit transmits the load current abnormality signal to a power management server at a remote location, and the power management server transmits a load current abnormality signal message to the administrator terminal and the user terminal of the corresponding customer.

The calculation processing means controls the individual load switch so that the charging power of the energy storage device (ESS) is selectively supplied to the individual load when the threshold value of the load current measured by the load monitoring means is exceeded do.

In addition, if at least one human body detection sensor is provided in the custody and the user sets the body detection function through the operation unit, the calculation processing unit detects the human body detection signal from the at least one human body detection sensor, And some of the individual load switches are tripped.

If the user sets a crime prevention function through the operation unit, the control unit of the calculation processing unit monitors whether a human body detection signal is detected by the human body detection sensor, When the detection signal is detected, a trespass detection message is generated and transmitted to the power management server, and the power management server transmits the trespass detection message to the user terminal of the resident of the corresponding customer.

When the user sets the collective control so that the lamp and the heat load except for the normal load requiring the constant power supply can be simultaneously shut off or returned through the operation unit, the operation processing unit groups and controls the individual load switches in a group .

1 is an overall system configuration diagram of an artificial intelligent distribution board according to the present invention.
2 is a detailed block diagram of an artificial intelligence distribution board according to the present invention.
3 is a detailed configuration diagram of the load monitoring means according to the present invention.

Hereinafter, the features of the artificial intelligence panel according to the present invention will be understood by the embodiments described in detail with reference to the accompanying drawings.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments. It is to be understood, however, that the invention is not intended to be limited to the particular forms disclosed, but on the contrary, is intended to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

1 to 3, the artificial intelligence panel according to the present invention is installed in a house such as a house or an office. The intelligent distribution board 100 installed in each customer can not only view the power distribution function but also the power quality information, real time energy usage and charge at a glance, and monitor the maximum value, the minimum value and the average value of the load state in real time And when the characteristic load of the L component such as the refrigerator and the air conditioner is activated, the built-in energy storage device (ESS) 130 operates to reduce the maximum load to reduce the electric charge.

In addition, the present invention provides an artificial intelligence distribution board 100 for supplementing the functions of setting the critical leakage current and the limiting leakage current to set and using the user's safety according to environmental conditions, When a danger is detected from the inside, information is transmitted to an administrator terminal 200 such as a smart phone or a PDA carried by a moving administrator using the Internet network so that quick action can be taken.

On the other hand, a main switch 101 is provided on the main line 101a for inputting or shutting off the main power into the receptacle from the power network, and a plurality of branch switches (for example, 102 are installed in the branch passage 102a.

The intelligent power distribution board 100 according to the present invention installed in such a cafeteria includes load monitoring means 110 installed on the individual load side load line 103a to monitor power consumption information of the individual load of the customer, An individual load switch 120 installed in the load side load line 103a for interrupting or restoring the input electric power and an energy storage device (ESS) 130 installed in the branch path 102a and capable of charging or discharging electric power, (ESS) 130 by selectively analyzing the power consumption information of the individual load monitored through the load monitoring means 110, or by selectively charging or discharging the individual load switch 120 And an arithmetic processing means (140) for controlling the opening and closing of the display device.

According to this configuration, the load with the highest power consumption in a household is mainly a refrigerator, a kimchi refrigerator, a washing machine, an air conditioner, etc. In order to save energy, can do. That is, when the load is activated, the energy storage device (ESS) 130 can be utilized to save the progressive charge by lowering the maximum load.

Hereinafter, the constitution of each part of the present invention will be described in detail.

First, the branch switch 102 and the individual load switch 120 may be configured as relays. However, not only can the response speed be high and the large power can be controlled with a minute pressure, but also the semi-permanent silicon controlled rectifier (SCR) It is possible to perform rapid power input and interruption.

The energy storage system (ESS) 130 is a device for enlarging a conventional small-sized secondary battery such as a lithium battery or storing large-scale power by other means such as rotational energy, compressed air, and the like.

On the other hand, the load monitoring means 110 can be selectively installed on a branch line of an individual load to be controlled in order to monitor power consumption information of the individual load. The load monitoring means 110 includes a meter current transformer CT (111).

Of course, the load monitoring means 110 may further include a meter transformer (PT) 112 for measuring the load voltage of the individual load, and a zero-current transformer (ZCT) 113 for detecting the leakage current of the individual load .

At this time, the load current detected by the CT (111) of the meter is classified into the starting current, the operation current, and the standby current according to the operation state. The reasons for this classification are that the operation current and the standby current use the KOP power and the startup current uses the charging power of the energy storage device (ESS) 130.

The load current measured by the CT converter 111 of the load monitoring means 110 is inputted to the arithmetic processing means 140. The arithmetic processing means 140 calculates the current Lt; / RTI >

At this time, the operation processing unit 140 may be configured separately from the control unit 141 and the memory 142, or may be formed of a microcomputer with a built-in memory. The operation processing means 140 classifies the values into an operation standby current average value, an operation state current average value, and a startup initial state current average value at the time of inputting a load current, and stores the values in the memory 142.

An energy storage device (ESS) 130 and an inverter 132 are provided in the branch path 102a to constitute a circuit so that the main power and the charging power of the energy storage device (ESS) 130 can be selected and used. In this case, charging and discharging switches 133 and 134 are provided at the front and rear sides of the energy storage device (ESS) 130 so that when the charging switch 133 is operated, the main power is supplied to the energy storage device (ESS) And operates the discharge switch 134 to operate when the charging power is to be supplied to the load after charging is completed. Of course, the control of the charging and discharging switches 133 and 134 is performed by the control unit 141 of the arithmetic processing unit 140.

In this case, there is provided an individual discharge switch (136) which is opened and closed by the arithmetic processing means (140) so as to selectively supply power to the individual load, through which a specific individual load, for example, The power supply can be performed.

Of course, the charging and discharging switches 133 and 134 and the individual discharging switch 136 can also be rapidly switched on and off by using a SCR (Silicon Controlled Rectifier).

According to this configuration, when the load current sensed by the CT converter 111 of the load monitoring means 110 suddenly increases in the operation waiting state, the control unit 141 of the calculation processing means 140 outputs the initial state The power supply of the energy storage device (ESS) 130 is supplied to the individual loads for a set time (for example, 2 minutes), and the power system is operated so as to be alternately operated so that the main power is supplied after a predetermined time has elapsed .

That is, when the load current suddenly increases in the standby state, the discharging switch 134 is operated to supply the charging power of the energy storage device (ESS) 130 together with the main power to the load, The switch 134 is closed so that only the main power is supplied to the load.

Meanwhile, the leakage risk of the building may be different depending on the aging state. Accordingly, the present invention classifies the leakage current of the individual load into the critical leakage current and the limiting leakage current, so that it can be immediately operated in any environment.

The load monitoring means 110 further includes a zero-current transformer (ZCT) 113 for detecting the leakage current of the individual load in order to detect the leakage current of the individual load.

The critical leakage current refers to a current value currently leaking from the individual load line 103a, and the limit leakage current is higher than the leakage current set to the threshold value. At this time, the trip current for interrupting the individual load switch 120 can be set to a sum of the threshold value and the threshold value. For example, if the leakage current of the current load is 10 mA and the expected leakage current is 5 mA, then the individual load switch 120 is cut off so that the leakage break function is activated when a 15 mA leakage current flows, .

To this end, the waveform of the leakage current is measured at the set time (for example, 30 minutes) in the ZCT 113 and stored in the memory 142 of the arithmetic processing means 140. At this time, the waveform in which the leakage current flows or does not flow in a small amount is stored as a normal waveform (or similar waveform) value. When the waveform of the leakage current input from the waveform transformer (ZCT) 113 is input to the operation processing unit 140, the control unit 141 reads the waveform stored in the memory 142, It is desirable to delete only a certain amount of data to reduce the amount of data that can be compared. Of course, the operation processing unit 140 determines that the waveform of the leakage current detected by the ZCT 113 is a waveform different from the waveform of the leakage current stored in the memory 142, (Power on and trip) control twice in a set time unit (for example, 10 seconds). The control unit 141 of the arithmetic processing means 140 restores the individual load switch 120 to the normal state when the leakage current is normal and blocks the individual load switch 120 when the abnormal signal is continuously detected, 143, and notifies the user terminal 202 such as a smart phone carried by the user.

The calculation processing unit 140 includes a communication unit 144 and transmits a leakage current abnormality signal of the distribution board 100 to the power management server 300 at a remote location via the communication unit 144, The controller 300 can notify the user terminal 202, such as the smartphone of the resident of the customer, of the leakage current abnormality signal message through SMS or the like to inform the user of the abnormality signal of the distribution panel and directly confirm the abnormality signal.

Of course, the power management server 300 transmits a leakage current abnormality signal message to the user terminal 202 of the resident as well as the administrator terminal 200 of the customer through the Internet to promptly cope with and prevent accidents.

Meanwhile, the operation processing unit 140 may perform an overcurrent shutdown function. In this case, the load current of the individual load is classified into the critical current and the limiting current in detail so that it can be operated immediately in case of danger.

  At this time, the critical current is a value set by the user as an average current which is used in daily use. The load current detected by the CT (111) for the instrument is collected in the calculation processing means (140) / RTI > In this case, the load current is repeatedly detected every set time (for example, 30 minutes), and the load current is calculated and stored as an RMS (root mean square) average value. The operation time set to the threshold value is preferably 0 to 60 seconds or less. For example, if the total installation of the customer is 220V, 30A and the normal current is 20A, set the threshold current to 20A.

The threshold current may be set by the user through the operation unit 145 and may be input through an IHD (In Home Display) 150 connected via a communication unit 144 via RS485 communication have.

The limit current is the value set by the user as trip value above the average current. It is set by referring to the allowable current of the wire and the load design current. For example, if the total installation of the customer is 220V, 30A and the normal current is 20A, set the limit current to 10A. When the current set at the limit value exceeds 10A, the load is cut off within 0 ~ 20 seconds. At this time, the trip current for cutting off the power supply to the load can be set to a value obtained by adding the critical current and the limiting current. For example, when the threshold current is 20A and the limit current is 10A, if 30A is inputted into the receptacle through the main circuit, it is judged as an overcurrent and the individual load switches 120 are cut off.

For this purpose, the waveform of the load current detected by the CT (111) is measured every set time (for example, 30 minutes) and stored in the memory 142 of the calculation processing means 140. At this time, the load current in use in the load is within the threshold value and is stored as a normal waveform (or similar waveform) value. When a waveform identical or similar to the waveform of the input load current is input to the calculation processing means 140, the waveform stored first in the memory 142 is deleted from among the waveforms detected by the instrumental current transformer (CT) 111 It is desirable to reduce the amount of data that can be stored by comparing only a certain amount of data. The controller 141 of the arithmetic processing means 140 may determine that the waveform of the load current detected by the instrumental current transformer (CT) 111 is an abnormal signal if it is a waveform different from the waveform of the load current stored in the memory 142 The individual load switch 120 is repeatedly turned on and off (power on and trip) by two times in a predetermined time unit (for example, 10 seconds). The control unit 141 of the operation processing unit 140 restores the individual load switch 120 normally when the load current is normal and blocks the individual load switch 120 when the abnormal signal continues to be detected, ) To output an alarm. Of course, such an abnormal signal is also transmitted to the user terminal 202 to notify the user.

The control unit 141 of the operation processing unit 140 transmits a load current abnormality signal of the distribution board 100 to the power management server 300 at the remote place through the communication unit 144 and transmits the load current abnormality signal to the power management server 300 An abnormal signal message is notified to the user terminal 202 or the administrator terminal 200 such as a smartphone of the corresponding resident's resident through an SMS or the like so that the abnormal signal can be directly confirmed and coped with by reporting an abnormal signal of the distribution board 100.

In this case, the communication unit 144 can perform data transmission through bidirectional communication using an intelligent watt-hour meter (AMI) 160 connected to a power management server 300 at a remote location and a communication module such as zigbee.

On the other hand, the individual load can be divided into a heat load and a light load as a load such as a living room power source, a room, a kitchen, an air conditioner, an ordinary heating power source, etc. When the threshold value is exceeded, May control the individual discharge switch 136 to supply the charging power of the energy storage unit (ESS) 130 to the individual loads.

That is, for example, if the load is 15A (4 branch circuit) light load 5A (2 branch circuit) and the average load 20A is set to the threshold current value, then if the detected load current exceeds the threshold current value, One load circuit supplies the charging power of the energy storage device (ESS) 130 to reduce the maximum current. At this time, the battery usage time of the energy storage device (ESS) 130 is preferably set to be within the built-in battery capacity.

In addition, when the charging power of the energy storage device (ESS) 130 is supplied to one electric load load circuit and the critical current value is exceeded, the charging electric power of the energy storage device (ESS) (ESS) 130 is set to be within the capacity of the built-in battery.

In order to use the charging power of the energy storage device (ESS) 130 as needed, the energy storage device (ESS) 130 preferably charges the charging device when it is determined that the electric charge is low, And when the maximum load is reduced during operation, control is performed so as to sequentially return to the main power source, which is the main power source.

The arithmetic processing means 140 periodically monitors the maximum value, the minimum value and the average value of the load current in real time and transmits them to the power management server 300 at a remote place. When the user inputs the real time power quality, And transmits it to the user terminal 202 of the resident of the corresponding customer.

When the collective control signal is input from the batch lamp and the heat transfer switches 180 and 181 for collectively controlling the power supply and cutoff of a plurality of lamp loads or heat transfer loads provided in the customer, Or controls the corresponding individual load switch 120 of the heat transfer load.

For example, when the batch light switch 180 is turned on, the calculation processing unit 140 activates the individual load switch 120 to turn on all the corresponding lamp loads and turns on the batch heat transfer switch 181 (ON), the arithmetic processing means 140 activates the individual load switch 120 to turn on all the heat load. The operation processing means 140 activates the individual load switch 120 to cut off the power to be supplied to all the corresponding lamp loads and turns off the batch heat transfer switches 181 when the batch lamp switch 180 is turned off, (OFF), the arithmetic processing means 140 operates the corresponding individual load switch 120 to cut off the power supplied to all the heat load.

On the other hand, a human body sensor 170 is provided in the customer in order to enable a user residing in the customer to perform the occupancy detection function and the security function at the time of going out. The human body sensor 170 may be an infrared sensor, for example, and may include one or more sensors.

The controller 141 of the arithmetic processing unit 140 detects the human body detection signal from one or more human body detection sensors 170 and if it is not detected during the set time, (Not shown).

In this case, the individual load switch 120 can be controlled automatically, for example, on the basis of the schedule of the family, such as a vacation trip, by time, day, and week, and automatically when there is no movement of the object. For example, when the human body detection signal is not input from the human body sensor 170 for a set time (for example, 10 minutes) because there is no movement of the object, the operation processing means 140 cuts off the power supply of the lamp load It is automatically turned off, and when the motion is detected, the power supply of the lamp load is performed again so as to be controlled to be turned on.

Of course, the user can set the room detection function through the user terminal 202 even while out of the house. The request information of the room detection function is transmitted to the power distribution server 300 and transmitted to the distribution panel of the set customer, The control unit 141 of the control unit 140 may perform a room detection function to monitor whether a human body detection signal is detected by the human body detection sensor 170. [

Next, when the user sets a crime prevention function through the operation unit 145, the control unit 141 of the calculation processing unit 140 monitors whether the human body detection signal is detected by the human body detection sensor 170, The intruder detection message is generated and transmitted to the power management server 300 through the communication unit 144. The power management server 300 transmits a trespass detection message through various types of data or SMS via the Internet To the user terminal 202 of the resident of the corresponding customer.

Also, the user can set a crime prevention function through the user terminal 202 of the resident even while out of the house. Such crime prevention function request information is transmitted to the power management server 300, and the operation processing means 140 And the control unit 141 may perform a crime prevention function to monitor whether the human body detection sensor 170 detects a human body detection signal.

In addition, the user can set the collective control so that the electric lamp and the heat load of the entire customer can be shut off or returned at the same time except for the normal load requiring the constant power supply such as the refrigerator through the operation unit 145, The control unit 141 groups and controls the corresponding individual load switches 120 in accordance with the grouping.

Of course, the user can set a collective control function through the user terminal 202 even while out of the office. Such collective control request information is transmitted to the power management server 300 and retransmitted to the distribution panel 100 of the set customer, 140 may perform a batch control function.

At this time, the user can perform the schedule control function by inputting the load time of the distribution board 100 for each customer, the sleep time zone, and the ROOM use time zone.

When the control unit 141 of the operation processing unit 140 transmits such a series of information to the power management server 300, the power management server 300 processes the power consumption amount information and the demand prediction information of the corresponding customer, And transmits it to the user terminal 202 of the resident of the customer and notifies the user of the occurrence of the progressive fee, and the information may further include alarm information.

That is, the power management server 300 collectively collects energy data such as power usage information and demand forecast information, and provides the collected energy data to the user so that the user can conveniently analyze the power consumption pattern change.
