First, the power check unit 11 receives the first power, which is the amount of power generated from the plurality of panel modules 100 generating power by converting sunlight or solar heat into electrical energy, and is charged according to the charged or charged power. The second power, which is a charge amount of the battery 30 that can be attached and detached and additionally provided to supply the power, is checked by checking the third power, which is the amount of power used by each of the plurality of loads 40 used to receive power, and the first power. And generating monitoring information about power, the second power, and the third power.

On the other hand, the power check unit 11 is also connected to the meter 50 as shown in Figure 2 for use of the late-night electricity to be described later can also check the amount of power of the late-night electricity applied through the meter, and also the meter 50 In addition to the above is connected to the power is sent out, that is, because the power is transmitted to the power transmission system 60 through the meter 50 when the extra power is transmitted to the KEPCO, the amount of power transmitted to the KEPCO when connected to the meter 50 can also be checked. Can be.

To this end, the power check unit 11 is connected to each component, calculates the amount of power based on the current and voltage checked from the sensor and the sensor to check the current and voltage flowing, and calculates the above-described first to third power amount It may be configured to include a processor or a sensor module for performing a function to check in real time or to check the cumulative production or supply.

In the present invention, the battery 30 is characterized in that the detachable and additional connection as described above. That is, the second power refers to power charged in the battery 30, and the check value for the charging power of the battery 30 may be sensed differently in real time according to the detachment and the additional connection of the battery. .

Since the battery 30 is detachable, the battery 30 is charged using the electric power produced by the panel module 100 or the late night electric power applied through the meter 50, and then a part of the battery 30 is separated to supply electric energy. Can be used to That is, in the present invention, the battery 30 may serve as a single power supply together with the panel module 100 and the late-night electric power, instead of performing a simple charging function of surplus power, and rather, the battery 30 is detachable. It can serve as an important independent power source.

In the present invention, the load 40 refers to an object that consumes power while performing a specific function by receiving power from the generated power, the late night electricity, and the battery 30 in the panel module 100. It can be understood that air-conditioning devices, lighting devices, electronic devices, household appliances are included in the general load 40 in the present invention. However, in the present invention, in addition to the example of the load 40 described above, an electric vehicle charging device and the like may be included in the load 40, and in the present invention, the rated voltage of the load 40 may be variously configured. It is done.

That is, the power checker 11 checks not only the generated power generated from the panel module 100 but also the charging degree of the battery 30 and the amount of power used by the load 40, thereby being very active as described below. In addition to efficient and efficient power management, the power produced for various purposes can be used to prevent waste of power and to build the most suitable system for environmentally friendly energy harvesting systems.

The interfacing unit 12 provides the monitoring information generated by the power check unit 11 to the user terminal 20, and inputs reservation information about power usage and a control request input for real-time power usage from the user terminal 20. It performs a function of receiving control information that includes.

That is, the interfacing unit 12 executes or accesses a result of a program, an application, or a website that can be executed or connected in order to use a function performed by the apparatus 10 in the user terminal 20 according to the functional sphere of the present invention. Output of the interface for using the output function, output of the use screen applying the above-described monitoring information to the output interface, reception of data input through the input means of the user terminal 20 for menus and input windows included in the interface, and According to the received data input is configured to perform the function of receiving the control information generated in accordance with the function of the interface.

In the present invention, the reservation information refers to the input for the control to determine the time, rather than the real-time control for the specific power use from the user terminal 20. That is, the control for using the function of the load 40 for a specific time or a periodic time period, not the control information for immediately supplying power to a certain load 40, that is, to use the function of the load 40. Means information. An example of this is shown in FIG. 5.

Referring to the screen 200 of FIG. 5, the user terminal 20 outputs interfaces 201 and 202 through which reservation information can be input. By using the user terminal 20, the user may be authenticated that his / her account may be validly requested to use the corresponding power, and after confirming the output of the corresponding interface 201 or 202, the user may input reservation information.

As shown in FIG. 5, the reservation information may select, for example, the type (load identification) of the load 40 to be supplied with power, that is, the target of use. Can be set automatically. In addition, the use time zone may be set to a periodic time zone as shown in, for example, FIG. 5, or control may be set to be turned on or off at a specific time of a specific date. Thereafter, the input button 203 may be selected to generate reservation information and transmitted to the interfacing unit 12.

However, as shown in FIG. 5 and as described below, the priority of use for the generated power may be set. Although not shown in FIG. 5, the user may check real-time, cumulative or specific time zones, and monitoring information for each specific time zone for the first to third powers using the above-described monitoring information. That is, you can check the current usage, accumulated usage, usage during a specific time, day of the week, time of day, date, and monthly usage. At the same time, however, as shown in FIG. 5, users may check and edit priority information of power usage for each object with respect to objects currently using power.

To this end, as illustrated in FIG. 5, the input button 203 may be dragged 204 to be assigned to a specific priority, and for example, a reservation for electric vehicle charging (EV charging) may be used as a third priority using the input button 203. Reservation information can be entered by setting the rank.

Returning to the description of FIG. 2 again, in addition to such reservation information, a control request input for real time power usage may be received as described above. The control request input is to perform a request for power usage in real time, which is almost the same as mentioned in the description of FIG. 5, except that only the input for time is excluded or the input for time is to be used from the present. It can be understood that there is a difference that only makes it possible. Of course, the reservation information and the control request input may be configured to be separately selectable from the interface to provide convenience to users.

That is, the interfacing unit 12, in the reservation information and the control request input from the user terminal, identification information of the load to be used, toggle information on whether or not to use and setting information on the use time and each load and the battery It is possible to receive and store the setting information on the priority between the charging for the power supply, the power transmission to the KEPCO. Since the reservation information and the control request input are information for controlling the power supply requested by the user, the reservation information and the control request input are stored in a memory or a database separately provided in the above-described computing device and the device 10, and the data request of the time or power control unit 13 is performed. And may be used to generate a control command transmitted to the power control unit 13 to control the power supply.

As described above, the power controller 13 may charge the battery 30 based on at least one of the control information, the monitoring information, and the late night electricity information received through the interfacing unit 12. Generate a control command for controlling the power supply to 40 and the power delivery to the KEPCO, and transmits the control command to the power distribution device 70 that receives the power and transmits it to the outside including a plurality of power converters and switching circuits It performs the function. Preferably, as described above, the control information (including reservation information and control request input) stored in the database or the like is loaded through the interface unit 12 to obtain the same effect as the control information received from the interface unit 12. .

Since the interfacing unit 12 performs the function of providing the monitoring information to the user terminal 20 as described above, the power control unit 13 may directly receive the monitoring information from the power check unit 11, but the interfacing unit ( 12).

As described above, the control command includes a meter 50 and a power transmission system 60 for charging the battery 30, supplying each of the plurality of loads 40 separately, and sending power to the KEPCO. In order to distinguish the power supply to the power supply, it means data generated by including all of the identification information of the power supply target, the specific power supply time, the applied voltage and the like.

On the other hand, as described above, the interface unit 12, in the reservation information and the control request input from the user terminal, identification information of the use target load, toggle information on whether or not to use, setting information on the use time and each load and Setting information about the priority of charging the battery and power transmission to the KEPCO may be received and stored in a database, and reservation information and a control request input may also be stored in a memory or a database as described above. When the control unit 13 generates the control command, not only the above-described reservation information and control request input, but also setting information on the priority of power use for each power supply target included in the control information and managed in the database. You can create a control command using. An example of this is shown in FIG. 6.

Referring to the screen 300 of FIG. 6, the control command may include identification information (O1) of the control target, information on the rated use voltage of the control dialogue, information on the priority of the control, information on the operation time, and the like. It can be configured to include. At this time, the information on the operation time may be deleted if it is not a control command based on the reservation information.

Returning to the description of FIG. 2 again, the setting information on the priority is information previously stored in the power control unit 13, and the basic rated voltage of the power converter 71, the specification of the battery 30, the panel module 100 and the like. ) May be automatically set by the specification, or may be set by a user input through the interface unit 12 described above. In addition, the priority may be set by being grouped by the load 40, the battery 30, the meter 50, or the like, or may be set in detail for each load 40.

Such a structure is shown in FIG. Referring to FIG. 3, the power control unit 13 may include a memory, in which the memory is inputted by the interfacing unit 12 described above or automatically set by default to identify each control information and power supply target. It can be understood as a configuration of a database containing information, all information necessary for generating a control command, that is, a data storing data that is transmitted, received, processed and managed to perform all the functions of the present invention.

In particular, the memory of the power control unit 13 shown in FIG. 3 is a concept of storing a specific control framework that is stored independently of the user's control information for at least basic control, that is, automatically set basic control commands 130. Can be understood. That is, it may mean a control command generated through a basic rule for power control which is basically set in using the apparatus 10 of the present invention.

For example, when the second power, which is the charge amount of the battery 30, is compared with the specification and the maximum charge amount of the currently attached battery 30, the control to stop the power supply to the battery 30 when no further charge is required. Command and use the power in the battery 30 when the third power amount, that is, the amount of power used by the load 40 that is currently being used, that is, consumes power, exceeds, for example, the first power that is produced. The control command may be the basic control command 130 described above.

At this time, the control information I transmitted to the power control unit 13 or stored in the database is applied to the above-described basic control command 130 by performing the function of the interface unit 12 described above, so that the final control command 131 is applied. Is generated and transmitted to a power distribution device 70 including a plurality of power converters 71 and switching circuits 72 as described above. Since the control command includes specific control commands for each of the power converter 71 and the switching circuit 72, the control command sent to the power distribution device 70 is based on the header information and the circuit characteristics. It is transmitted to the power converter 71 and the switching circuit 72 to perform a function corresponding to the control command.

Returning to the description of FIG. 2 again, the power control unit 13 may generate a control command by an input from the user terminal 20 when generating the control command, but based on the monitoring information and the control information, the specific control. The command can be automatically generated according to the situation and transmitted to the power distribution device 70.

In this case, the power control unit 13 may generate a control command under the environment as shown in FIG. 7. That is, as a function of the power control unit 13, the power control function 132 is a production power (G) by the panel module 100, low-cost late-night electricity (N) available from KEPCO, charge amount (B), load of the battery Based on the information on the specifications (L) and power transmission (T) such as the power consumption of the user, the target of the power is automatically selected regardless of the user's input or considering the input, and the power is supplied to the target. To generate a control command.

Returning to the description of FIG. 2, the following embodiments may be implemented for the above-described automatic control command generation.

[First Embodiment]

If no control information is input at a specific time point through the interface unit 12, it is predicted that no control command will be generated by the control information at a specific time point, or no control information is received in real time. In other words, if the control information is not received, the power control unit 13 automatically generates a control command based on the setting information on the priority, for example, to perform the charging function for the battery 30 first. Can be transmitted to the power distribution device 70.

In the present invention, the battery 30 is detachable and detachable when used, so that the battery 30 can be used in other equipment other than the load 40 connected to the power distribution device 70, thereby greatly improving the use range of the system. That is, in the existing system, the battery is charged only when surplus power is present. In the present invention, since the charging of the battery 30 is a very important factor as described above, when there is no control information for the use of power, The function of the above-described power control unit 13 for automatically performing a function of automatically charging the battery 30 is performed.

Second Embodiment

In the second embodiment, the power control unit 13, for example, when transmitting a control command to the power distribution device 70, the control information, specifically, in the second embodiment as information generated through the reservation information and the third power The amount of available power calculated based on the amount of power used as the third power at one time point and the environmental information and monitoring information received from the outside is compared.

The amount of power used is based on the control information on the power usage corresponding to a certain point in time, comparing all the reservation information included in the control information and the input of the control request, and all the power consumption at that point for the expected target power usage. Can be calculated by accumulating the amount of power used according to the specifications of each target. The environmental information received from the outside may be weather information at any one point to predict the amount of power produced by the panel module 100, light quantity information based on the weather information, and the like.

As a result of the comparison, when the amount of power used, preferably the amount of power expected to be used at any one point, is greater than the available amount of power by the first value, the power supply to the battery 30 and the power transmission system 60 at any point in time is set to a priority value. At the same time, the control command generates the control command to further provide the load 40 through the power distribution device 70 to the first value, that is, the amount of power expected to be insufficient, from the battery 30. That is, regardless of whether the control information includes the control information desired to be charged for the battery 30 and whether the control information corresponding to the request for power transmission is included, the control command is automatically generated to perform the above-described functions.

In this case, when the interfacing unit 12 receives a signal from the power control unit 13 indicating that such a case has occurred, the interfacing unit 12 uses a first power value greater than the available power amount according to the signal received from the power control unit 13. If it is determined as many, the user terminal 20 generates power control request information for requesting input of warning information indicating that the amount of power used exceeds the amount of available power and control information for adjusting the amount of power used at any one time. Can be sent to. An example of this is shown in FIG. 6.

Referring to the screen 210 of FIG. 6, information indicating that the amount of power is expected to be insufficient at a specific time zone (20 o'clock) is output to the user terminal 20, and the user is output to the screen 210 of the terminal 20. Editing Control Information Select menu 211 to edit control information.

Through this, the user confirms that the power control request information has been received by a means such as a pop-up to his terminal, and uses the control information editing menu included in the above-described interface, whichever user wants to use at that time. Power can be suitably used through an edit input such as canceling a power supply input to a control object.

However, in the third embodiment, the power control unit 13 is the control information and the information generated through the third power when transmitting a control command to the power distribution device 70 as in the second embodiment, The amount of power used as the third power at the time point is compared with the amount of available power calculated based on environmental information and monitoring information received from the outside.

When the amount of power used is greater than the amount of available power by the first value, the third embodiment, unlike the second embodiment, charges the battery 30 in descending order of priority based on the control information at any one time. Generate a modified control command to remove at least one of the power supply to the multiple loads 40 and the power delivery to KEPCO from the control command to be generated at any point in time so that the amount of power used is less than the available power do.

That is, unlike the second embodiment, priority is given to the application of priorities, and the power usage is automatically controlled based on the priorities for all the power usage targets. This can achieve a more excellent effect in terms of power saving than in the second embodiment.

On the other hand, when the amount of power used is less than the available amount of power by the second value, the control to provide the power transmission system 60 through the power distribution device 70 at any point in time, similar to the second embodiment Create a command.
