Description

The present invention collects and processes information on the use of electricity such as electricity, gas, and water, mainly in households such as dwellings and apartments, and displays the power consumption and consumption charges on each display device. The present invention relates to a residential distribution board that controls the operation of equipment that consumes electric power according to the set goals and supports proper use.

In recent years, there are concerns about the depletion of the earth resources necessary for people to live their lives, and there is an urgent need to respond to environmental problems such as global warming due to the effects of carbon dioxide, etc. generated by consuming resources. ing.

In companies, efforts to reduce carbon dioxide emissions and measures to acquire carbon dioxide emission rights are proceeding at a rapid pace.

On the other hand, energy conservation is advancing at home as part of efforts to save global resources and prevent global warming. The burden of charges associated with the use of energy is a concern for households, and as a means of promoting energy conservation, the following devices have conventionally been used to monitor and display energy usage. Is disclosed.

In Patent Document 1, the energy-saving effect after the introduction of energy-saving devices has not been specifically grasped in the past, and there are many cases where multiple energy such as electric power and gas is used in ordinary households. In view of the fact that it is necessary to grasp and manage the energy consumption of the whole as a whole, the target value of the consumption of multiple energy such as electric power and gas used in each household is set as accurately as possible, and the overall energy consumption is A home energy-saving support method and apparatus for the purpose of helping to reduce the power consumption are disclosed.

In the energy saving support method and device for home use, the target consumption value of each energy is converted into the light heat cost which is a common unit, and the target light heat cost corresponding to the sum of the plurality of energy consumption target values is obtained. This is characterized in that the actual light heat cost corresponding to the sum of a plurality of actual energy consumption values is obtained by converting the actual heat consumption value into the light heat cost, and the target light heat cost and the actual light heat cost are compared and evaluated.

According to this configuration, consumption of a plurality of energy such as electric power and gas is evaluated in terms of money as a whole, so that fluctuations in energy consumption can be easily grasped as a household balance. Further, it is disclosed that, for example, in a household that uses both electric power and gas for air conditioning, it is possible to manage the energy consumption as a whole while avoiding the troublesome management of energy consumption individually.

Further, in Patent Document 2, since the ratio of individual consumption to the energy consumption of society as a whole is small, it is difficult for each individual to perceive the necessity of reducing energy consumption as his own problem. Because energy consumption is not thoroughly reduced, and energy usage fees are paid in units of 1 to 2 months, so the cost perception of energy becomes dull and there is a tendency to consume energy carelessly. As a result, in view of the fact that the individual energy consumption is not thoroughly reduced, and that the energy consumption of each individual device is difficult to understand, the individual energy consumption cannot be reduced thoroughly. Energy data management system and energy data tube that can grasp the energy consumption of your home in detail and simply Apparatus, energy data management method and energy data management program, and energy data management system, energy data management apparatus, and energy data that are easy to understand for the residents of ordinary households An invention made for the purpose of providing a management method and an energy data management program is disclosed.

The invention of Patent Document 2 is an energy data management system that records and displays energy usage data in a house, and measures a gas meter that measures the gas usage in the house, and measures water usage in the house A water meter, a breaker that allows a current to be supplied to the electrical equipment in the house, and a power value of the breaker is measured periodically, and the usage data is received from the meter. An energy data management device that stores data and data of the power value, and a display device that displays information received from the energy data management device, wherein the energy data management device receives the usage received from each of the meters Usage data storage means for storing quantity data and data of the power value obtained by regular measurement, and gas per unit period of the house Target value storage means for storing target usage values for water and electricity, and the data stored in the usage data storage means and the target when there is a request from a display device connected to the energy data management device A predetermined period display screen that simultaneously displays the gas, water, and electricity usage values within a predetermined period and the gas, water, and electricity target usage values during the predetermined period using the target usage values stored in the value storage means. Means for generating data and transmitting it to the display device, the display device comprising display means for receiving the data of the display screen for a predetermined period and displaying the display screen.

Also, in Patent Document 3, a meter for measuring received power is usually constructed so as to display the amount of power accumulated since installation, which is inconvenient for the purpose of monitoring the power usage state. There is no general equipment suitable for this purpose. Also, especially in buildings and factories where the amount of power used is large, there are generally managers related to utilities such as power. However, it is important to know the power usage status in real time especially during times when power usage fluctuations are large. It is generally difficult from the viewpoint of cost management and effective utilization of resources because the use site and managers are systematically separated. However, in view of the fact that there is no device suitable for monitoring the power usage state suitable for such purposes, the power usage is suitable for simultaneously monitoring the power usage state in buildings, factories, etc. where power consumption is generally large. An invention made for the purpose of providing a state monitoring method and apparatus therefor is disclosed.

The invention of Patent Document 3 detects at least the instantaneous power as the power usage, wirelessly transmits the detected usage, and when the receiving means receives the wirelessly transmitted signal, the usage is converted to the instantaneous power. Or, it is displayed in comparison with a target value stored in advance by the amount of electric power obtained by integrating it, and a power usage state monitoring time zone is determined in advance, and the comparison result in the monitoring time zone is displayed at least in a graph. It is what I did.

(Operation of support for proper use of power)
Next, the operation of the residential distribution board 1 will be described. First, the control operation of the residential distribution board performed according to the set target value of power consumption will be described with reference to FIG. Each determination is made by the calculation unit.

First, the operation button is operated for the amount of power used as a target, and a target value for the amount of monthly usage is set as shown in FIG. 6 (step S001).

The residential distribution board starts measuring the amount of power used (step S002), and based on the monthly target value set in step S001, apportions the amount that can be used every day and uses the current day However, the calculation unit determines whether or not the target value that can be used on the day is exceeded (step S003).

Then, when the set target value is exceeded, the operation is controlled to be stopped in order for the control target devices set in advance as shown in FIG. 8 (step S004). If the target value is not exceeded, the process returns to step S002 and continues. In addition, it is good to determine the control order about a control object apparatus suitably.

Then, the passage of time is monitored, and the calculation unit determines whether or not the current day is over and the next day is reached (step S005).

If it is the next day, the stop control of the device is reset, and the initial state is restored (step S006). If it is the current day, the process returns to step S002 and continues. Here, the amount of power used is prorated on a daily basis, so the amount of power that can be used on a daily basis is determined. When the next day is reached, re-counting is started for the amount of energy that can be used on that day. To do. If the set target value is significantly exceeded and the usage amount that can be used on the next day has already been used, the target value for the usage amount that can be used up to that day is exceeded when the next day is reached. Therefore, the operation of the target device is controlled to be stopped (step S004).

Next, as described above, when the operation of the target device is controlled to stop, and then the user manually controls to start the operation of the device, an intervention operation is performed to provide appropriate energy support. A case where the operation of the target device is stopped again after a predetermined time has elapsed will be described with reference to FIG.

First, the operation button is operated with respect to the amount of power used as a target, and a target value for monthly usage is set as shown in FIG. 6 (step S101).

The distribution board for housing starts measuring the amount of power used (step S102), and based on the monthly target value set in step S101, apportions the amount that can be used on a daily basis and uses that day. However, the calculation unit determines whether or not the target value that can be used on the day is exceeded (step S103).

Then, when the set target value is exceeded, the operation is controlled to be stopped in order for the control target devices set in advance as shown in FIG. 8 (step S104). If the target value is not exceeded, the process returns to step S102 and continues.

When the operation of the target device is controlled to stop, it is determined whether or not the target device is manually turned on (step S105).

If the target device is manually turned on, it is determined whether or not a predetermined time has elapsed (step S106). If the target device is not turned on manually, the process proceeds to step S108.

Then, when the predetermined time has elapsed, the operation of the target device is stopped again (step S107). If the predetermined time has not elapsed, the process returns to step S105.

Then, the passage of time is monitored, and the calculation unit determines whether the current day is over and the next day is reached (step S108).

If it is the next day, the stop control of the device is reset, and the initial state is restored (step S006). If it is that day, the process returns to step S105 and continues. Here, the amount of power used is prorated on a daily basis, so the amount of power that can be used on a daily basis is determined. When the next day is reached, re-counting is started for the amount of energy that can be used on that day. To do. If the set target value is significantly exceeded and the usage amount that can be used on the next day has already been used, the target value for the usage amount that can be used up to that day is exceeded when the next day is reached. Therefore, the operation of the target device is controlled to be stopped (step S104).

As for the stop control of the target device, as shown in FIG. 8, the operation is controlled to be sequentially stopped with respect to the control target device set in advance, but the stop control interval is several minutes. For example, it may be set as appropriate, such as several hours. Moreover, you may comprise so that stop control may be performed simultaneously instead of performing stop control of a control object apparatus in order.

Further, the predetermined time shown in step S106 is set to 3 hours in the present embodiment. It should be noted that the predetermined time may be appropriately determined.

Next, the control operation performed according to the contract current of the current limiter provided in the electric circuit to which the residential distribution board 10 is applied or the rated current of the main switch will be described.

If too much electricity is used in the circuit, the current limiter and main switch provided in the circuit will operate, causing the entire dwelling unit to be out of power, making it extremely inconvenient for the user. In the residential distribution board 1, the instantaneous amount of electricity used as electric power is contracted for the current limiter provided in the electric circuit. When the current or the rated current of the main switch is exceeded, the operation of the target device is controlled so that no power failure occurs.

When the magnitude of the current of the circuit measured by the measurement / control unit exceeds the contract current of the current limiter or the rated current of the main switch, the control target device as shown in FIG. The operation is stopped and controlled in order.

For example, if a current limiter is provided, for the contract current of the current limiter,
The magnitude of the current in the circuit is
If 110% to 120%, stop control is performed in 45 seconds,
If it is 120% to 140%, stop control is performed in 15 seconds,
If it exceeds 140%, stop control is performed in 2 seconds.

In addition, when a main switch is provided in the circuit, the magnitude of the current in the circuit is compared to the rated current of the main switch.
If it is 100% to 120%, stop control is performed in 45 seconds,
If it is 120% to 140%, stop control is performed in 15 seconds,
If it exceeds 140%, stop control is performed in 2 seconds.

Then, stop control is performed in order, and if the magnitude of the current flowing in the electric circuit becomes less than the predetermined current value, the operation on control is performed in the opposite order to that when the stop control is performed. . For example, when the rated current value is 60 A, if the current limiter is provided, the operation on control is started at 52 A, and if the current limiter is not provided, the current limiter is set to 48 A. To start operation on control.

In the present embodiment, the stop control is performed at intervals of about every 3 seconds, and the operation on control is performed every about 10 seconds. These time intervals may be set as appropriate.

In addition, in the residential distribution board 10, the residential distribution board has controlled the operation of the target device for the purpose of more effectively promoting the proper use of energy, To what extent the instantaneous usage is relative to the contract current of the current limiter installed in the circuit or the rated current of the main switch, and the ratio of the current usage to the set target value The proportion of the ratio is indicated on the display unit 206 of the operation / display unit 200 and the display unit 301 of the display device 300.
It is configured to display.

That is, when the operation stop control is performed because the system exceeds the set target value for the operation stop control of the target device, each display unit 2061 is displayed on the display unit 206 of the operation / display unit 200. And 2062 are alternately turned on / off repeatedly so that it is possible to visually recognize that the operation stop control has been performed because the set target value has been exceeded, and an instantaneous amount of electricity used as electric power is provided in the electric circuit. When the operation stop control is performed because the contract current of the current limiter or the rated current of the main switch is exceeded, the display units 2061 and 2062 are simultaneously turned on / off in the display unit 206 of the operation / display unit 200. By repeatedly turning off the light, it is visually confirmed that the operation stop control was performed because the contracted current of the current limiter or the rated current of the main switch was exceeded. It has been cut way.

In addition, the color of the display unit 206 indicates how much the instantaneous amount of electricity used as electric power is relative to the contract current of the current limiter provided in the electric circuit or the rated current of the main switch. , By changing the ratio according to the ratio, it can be visually recognized. In this embodiment, the color of the display unit is
The ratio of the amount of operating current to the contracted current of the current limiter in the circuit or the rated current of the main switch is
When it is less than 20%, it is blue,
When it is 20% to 40%, it is light blue,
When it is 40% to 60%, it is green.
60% -80% is yellow,
80% to 100% is purple,
When it exceeds 100%, it is displayed using light emitting diodes corresponding to all colors so that it becomes red.

Further, as shown in FIG. 11, the display on the display unit 206 changes the color of the area surrounding the character displayed as “use rate (vs. target value) 100%” according to the use rate. By doing so, it is possible to visually recognize the ratio of the current usage amount to the set target value. In this embodiment, the color of the area surrounding the character is the ratio of the current usage amount to the set target value.
When it is 80% or less, it is blue,
When it is 80% -90%, it is green.
90% to 100% is yellow,
100% to 110% is orange,
When it is 110% or more, data is generated by the video data generation unit so that the color is red.

It should be noted that the color change and the ratio classification may be changed as appropriate so that the user can see how much power is being used.

In addition, the calculation unit is provided with a storage unit that stores predetermined audio data notified from the notification unit 207. The audio data is A “too much electricity is used”, B “the device is about to stop control soon”, C “the device is controlled to stop after XX seconds”, D “the target value has been exceeded. As a result, the device was controlled to stop. ”, D“ How is energy saving? ”And so on Data is stored.

And the ratio of the magnitude of the current used to the contract current of the current limiter in the circuit mentioned above or the rated current of the main switch is
When 100% to 110%, voice data A and B are notified every 180 seconds,
When 110% to 120%, voice data A and B are notified every 10 seconds, voice data C is notified after 40 seconds,
When it is 120% or more, the voice data A is notified every 5 seconds, and the voice data C is notified after 15 seconds.

In addition, the ratio of the current usage to the set target value of power usage is
When 80% -90%, voice data D is notified every 30 minutes,
When 90% to 100%, voice data D is notified every 5 minutes,
When 100% to 110%, the voice data A and D are notified, and after the device is controlled to stop, the voice data D is notified.
When it is 110% or more, the audio data A is notified, and after the device is controlled to stop, the audio data D is notified.

In addition, the residential distribution board 10 performs an arithmetic process based on the measurement result by the measurement / control unit 100 and the measurement data by the operation / display unit 200 in order to grasp the amount of electric power used, thereby obtaining the current energy. The amount of usage, the cumulative amount used from the past, and the comparison with the past usage are displayed in a graph, and the user can easily browse these information. In FIG. 12, the amount of electricity used is converted into the amount of heat for grasping the use of energy, and the cumulative amount used from the past is displayed in a graph.

The operation unit of the operation / display unit 200 is provided with a data storage area. By referring to and reading data stored in the storage area, the horizontal axis is a time axis and the vertical axis is a heat quantity. It has become.

FIG. 13 shows a graph for comparing the current power consumption state and the past power consumption state. Information such as a measurement object and a measurement time is added to the data measured by the measurement / control unit 100 and stored in the storage area together with the information. For this reason, the usage amount of a specific measurement target at a certain point in time in the past is read out and processed together with the current power usage amount, so that the horizontal axis is the time axis and the vertical axis is the power amount. Yes.

As described above, according to such a distribution board for home use, the usage state of energy can be seen on a daily basis, the operation can be easily performed, and the user can set the target value of the usage amount by himself / herself. It is possible to easily check visually or aurally whether the current state is excessive or marginal with respect to the target value. When the device is in use, the power to the device to be controlled is automatically turned off, and an intervention operation is performed so that the user can feel that excessive power is being used. A system capable of providing support for proper use can be provided. In addition, when this system is introduced, it is possible to provide a residential distribution board that can save wiring work related to the introduction and that can be performed with reduced wiring.

It should be noted that the present invention is not limited to the above-described embodiment, and can be appropriately applied as necessary without departing from the gist of the invention.

For example, a storage area is provided in the calculation unit 102 provided in the measurement / control unit 100, and the measurement data measured by the power consumption measurement unit 101 is stored together with the measurement target type and the measurement time, and the operation / display is performed. You may make it read the data memorize | stored from the unit 200 as needed. As a result, when there are a plurality of measurement / control units 100, it is not necessary to store all measurement data on the operation / display unit 200 side, the capacity of the storage unit provided in the operation / display unit 200 can be reduced, and the cost can be reduced. However, it is possible to provide a residential distribution board that supports the proper use of electric power. The transmitter / receiver provided in the measurement / control unit 100 and the measurement / control unit 200 appends identification data for identifying each other to the communication data, so that the data from which measurement / control unit is unique. This makes it possible to determine which measurement / control unit the data is from.

In addition, the transmitting / receiving unit is configured using a specific low-power radio system, but in addition, a weak radio system, a Bluetooth (registered trademark), or other commonly used radio system or other than a radio system may be used. Alternatively, a power line carrier type communication unit that superimposes measurement data on the power line may be provided by using a power line that has already been constructed.

Further, although the home automation system is used as the control method for the control target device, the power source of the control target device may be controlled to be turned on and off by relay control. The relay may be provided in the control unit of the measurement / control unit 100 and may be connected to the power line of the control target device 400, or may be installed near the control target device 400, and the control unit may include a relay. A signal line for outputting a control signal may be provided.

Further, the measurement / control unit 100 and the operation / display unit 200 are integrated with the measurement / control unit 100 and the operation / display unit 200, and only the power consumption measuring unit 101 is separated. You may comprise so that various control may be performed by transmitting the output from a measurement part by a transmission / reception part, and processing the obtained measurement data. As a result, the power consumption measuring unit can be reduced in size, and restrictions on the mounting location for the measurement target can be reduced. In addition, the amount of data relating to the transmission of wireless communication data performed between the measurement / control unit 100 and the operation / display unit 200 can be reduced, the possibility of being unable to perform control due to a communication error, and the degree of influence due to the inability to perform control. Can be reduced.

In the above-described embodiment, the target value can be used every day by setting the monthly target value for the comparison of the actual usage amount with respect to the power usage target value and the control of the electrical equipment. The power consumption is apportioned, and when the total value of the daily usage reaches the amount of power that can be used every day, the operation state of the electric device is controlled in a direction in which the power consumption decreases.

That is, as shown in FIG. 14, even if, for example, the amount of power used exceeds the apportioning line indicated by the dotted line in the figure, until the power that can be used on that day is reached, The electrical panel does not control the operation of electrical equipment. For this reason, operation control is performed when the use of power reaches a in the figure.

Then, on the next day, electric power can be used up to b in the figure, so that electric equipment can be used.

In consideration of the convenience of the user's life and the degree of necessity of the electric equipment, the electric equipment can be operated manually even after the operation control.

In addition, regarding the comparison of the actual usage amount with respect to the target value of power consumption and the control of electrical equipment, as a control method that pays more attention to energy conservation, the judgment whether or not the above-mentioned segregation line has been exceeded, instead of every day, The calculation processing may be performed by a program stored in the calculation means so as to be performed at finer time intervals such as time units or minute units.

As a result, it is possible to shorten the time until operation control is performed when the amount of power used exceeds the size indicated by the apportioning line shown in FIG. 15, and the use of power shown in FIG. When the condition is the same, the operation control is performed with the usage amount indicated by c in FIG. 15, and the same user can feel early that he / she has used too much electric power and can easily recognize it. In this way, the residential distribution board can provide support so as not to exceed the usage apportioned relative to the initially set target value.

In addition, the comparison of the actual usage with respect to the power usage target value, and the control of electrical equipment, in addition to increasing the degree of independence of the user's energy conservation efforts, the operation behavior of residential distribution boards As a control method for reducing the degree of intervention related to the above, it may be calculated by a program so that the determination as to whether or not the apportionment line has been exceeded is made not in every day but in a longer period such as a month.

As a result, even if the apportionment line is exceeded during the month as shown in FIG. 16, the residential distribution board does not control the operation of the electrical equipment until the power that can be used for the entire month is reached. That is, operation control is performed when the amount of power used reaches d in the figure. And the next month, you will be able to use electrical equipment.

In addition, as to whether or not to perform operation control, if the power used is smaller than the above-mentioned segregation line at certain time intervals (daily, hourly, monthly, etc.) At the next interval, the amount of power that can be used is relatively large because of the addition of the amount of power that should have been available at the previous interval, but the power usage is leveled at each interval. For the purpose of continuing energy conservation awareness, even if the power used is smaller than the above-mentioned segregation line, the amount of power that should have been available at that interval is added to the calculation of the power consumption at the next interval. Instead, the calculation processing may be performed by a program so that the energy saving direction is as much as possible.

If the power used is smaller than that of the above-mentioned segregation line, the amount of power that should have been available at that interval is added to the calculation of the amount of power used at the next interval, and calculation processing is performed. You may comprise.

In addition to electric power, for the purpose of providing support for the use of living energy, such as gas and water necessary for living, in order to make the use of the living energy appropriate, for example, The amount of power used is smaller than the above-mentioned segregation line, but if the usage amount of gas energy or water exceeds the segregation line and exceeds the usage amount, it corresponds to the surplus with respect to the target value of the power. Convert the amount of carbon dioxide equivalent to be converted into the amount of gas energy and water consumption, subtract the amount from the excess amount, and interchange, and support various living energy as a whole You may comprise.

Furthermore, the field of view is expanded from a unit such as a household to a unit such as a region, and a target value for use of living energy is set for each region. If a surplus occurs in a certain home, the surplus is used as a living energy use. The system may be configured so that the amount of household energy consumption is appropriate and allocated to households that have exceeded the amount.

In this case, for example, a setting value of the amount of use of living energy in a predetermined area, user information that participates in the system, a server device that stores the amount of living energy used in each home to which the user belongs, and information on the server are stored. The system is configured with an operation / display unit equipped with a communication unit so that it can be acquired, and a measurement / control unit that measures the amount of energy consumed in each home.

In the server device, target value data in each household, life energy usage data, surplus or excess information on usage with respect to the target value, energy saving level, contribution information to the region, and target value data in the region, Data on usable amount of usable living energy is made into a database and the information is accumulated in time series.

For households whose energy consumption exceeds the target value, it is determined whether or not the usage can be reduced to the target value or less in the household at a predetermined time interval such as the current month or year. In addition, allocation processing is performed from the surplus in the region.

At this time, for the households that provided the surplus, the data in the database was updated by increasing the contribution to the region, and for the households to which the surplus was allocated, the data in the database was decreased by reducing the contribution to the region. Update. Regarding the contribution level information to the region, the basic value is set to zero. If the contribution level increases, 1 is added. If the contribution level decreases, 1 is decreased. An arithmetic process may be performed by a program so as to determine the degree of contribution based on the total value in a predetermined period.

In addition, every year, the contribution to the community in each household is aggregated, and based on the contribution data, the usage fee for living energy is increased or decreased, and various taxes such as resident tax are increased or decreased. The system may be configured to process the program, store this information on the server, and determine the charge / tax collection amount for each household based on the stored life energy fee data and various tax data. .

In addition, the database includes, as control operation record data of the life energy appropriate use support system, the number of times the life energy appropriate use support system has performed operation control of the control target device, the type of control target device that has performed operation control, Operational status of the life energy appropriate use support system, such as the number of times of operation control for each control target device, the date data on which the operation was performed, and temperature measurement means such as a temperature sensor. In addition, data representing the surrounding environment state may be recorded.

The storage area for recording these data may be a storage area provided in the calculation unit, or a storage unit may be separately provided and stored in the storage unit.

Using these data, the operation status of the life energy appropriate use support system in the past is displayed as a list or graph by the calculation unit, and the user later browses the operation status of the life energy appropriate use support system. Therefore, it may be configured so that it can be used as an opportunity for study to appropriately take measures for energy saving.

As a result, it is possible to provide more effective support for the proper use of living energy, and it is caused by the depletion of global resources and the consumption of resources necessary for people to live their lives. The response to environmental problems such as global warming due to the effects of carbon dioxide, etc. can be promoted with mutual assistance in each household and the entire region.

Since the present invention is a residential distribution board that supports the proper use of electric power in dwelling units, it is introduced into ordinary households, and it is used by companies for resource depletion and global warming. There is a possibility that it can effectively tackle environmental problems in combination with efforts to prevent environmental problems.
