Abstract

PROBLEM TO BE SOLVED: To easily recognize whether energy consumption tends to be saved in an optional period designated by a user.SOLUTION: An integration amount storage means 12 sequentially stores integration amounts calculated by a first integration amount calculation means 10 on a predetermined time basis by being combined with calculation dates. When a user designates a starting date and an optional period by a period designation means 14, an ending date calculation means 15 calculates an ending date from the starting date and the optional period designated by the period designation means 14, and an integration amount reading means 16 reads, from the integration amount storage means 12, integration amounts at both the ending date calculated by the ending date calculation means 15 and the starting date input by the user based on the date information. A second integration amount calculation means 17 calculates energy consumption between the starting date and the ending date by obtaining a difference between the integration amount at the ending date and that at the starting date.

Description

  The present invention relates to an information output device for a combined heat and power device that outputs information related to at least one of gas, power, and water used in a home where the combined heat and power device is installed.

  As an information output device that outputs information related to gas and water in a conventional home, there has been one disclosed in Patent Document 1. FIG. 4 is a block diagram of a conventional example described in Patent Document 1. In FIG.

  In FIG. 4, the measuring means 400 measures the amount of gas and water used periodically, and outputs the measured values to the integrating means 401. The integrating means 401 integrates the measured values of the gas amount and the water amount.

  In FIG. 4, the calendar unit 402 outputs time data to the storage unit 403 while measuring time based on the calendar. The storage unit 403 stores the integrated value integrated by the integrating unit 401 and the time data output by the calendar unit 402 in association with each other.

  The data stored in the storage unit 403 can display the gas and water consumption for each period to the user by displaying the integrated value together with the date and time on the display unit 404. The period-by-period integration management unit 405 instructs the storage unit 403 to store the time data and the integrated value in association with each other for a predetermined period, and resets the integrated value and restarts the integration for the integrating unit 401. Is responsible for directing.

  Normally, the integration unit 401 integrates the measurement values output from the measurement unit 400. However, when a reset and integration restart signal is input from the period-based integration management unit 405, the integration value is temporarily set to zero. Reset and restart integration from zero.

  For example, when the period-based integration management unit 405 manages the integration data every day, the period-based integration management unit 405 stores the integration value and time data in association with the storage unit 403 at the time of 24:00. Outputs a storage instruction. After that, the integration management unit 405 for each period outputs reset and integration restart to the integration unit 401, so that the integration unit 401 resets (deletes) the previous day's integrated value to zero and starts re-integration. Thus, the integrating means 401 can start integrating the gas amount for the day.

  By repeating this operation every day (every time at 24:00), the storage unit 403 can accumulate daily gas and water consumption. That is, in this conventional example, the integrated value stored in the storage unit 403 is the consumption of gas or water in units of periods indicated by the time data. The display means 404 indicates the daily gas and electricity consumption when the time data indicates the day, and indicates the monthly gas and electricity consumption when the month indicates the month.

  With the above configuration, the storage unit 403 stores the accumulated value and time data in association with each other for a predetermined period (year, month, day, etc.) in the calendar. And the amount of water consumption) can be confirmed on the display means 404.

  Hereinafter, preferred embodiments of a fuel cell power generator of the present invention will be described in detail with reference to the drawings. In the following description, the same or corresponding parts are denoted by the same reference numerals, and redundant description is omitted. Further, the present invention is not limited by this embodiment.

(Embodiment 1)
FIG. 1 is a block diagram of an information output device of a combined heat and power device according to Embodiment 1 of the present invention, and FIG. 2 is a calculation method of consumption for an arbitrary period in the information output device of the combined heat and power device of the same embodiment. It is explanatory drawing for demonstrating.

  As shown in FIG. 1, the information output device 100 of the combined heat and power system of the present embodiment includes a home total power consumption measuring means 1 that measures the total power consumption in the home, and the amount of power purchased from the power company. A power purchase amount measuring means 2 for measuring the amount of power purchased, and a power sale amount measuring means 3 for measuring the amount of power sold to a power company out of the power generated by a solar power generation system (not shown) installed at home. Yes.

  Furthermore, the information output device 100 includes a power generation amount measuring unit 4 that measures a power generation amount generated by a combined heat and power supply device (not shown). Here, the combined heat and power unit is installed in a home, and a hydrogen generator that reforms city gas using water to generate hydrogen, and electrochemically generates hydrogen and air generated by the hydrogen generator. A fuel cell stack that generates electricity by reacting with the fuel cell stack, and is configured to collect the heat generated during power generation of the fuel cell stack and store the hot water for use in hot water supply.

  The information output device 100 includes a household total gas consumption measuring means 5 for measuring the total consumption of city gas or propane gas in the household, and city gas or propane used by the combined heat and power supply device for power generation. Power generation gas usage measuring means 6 for measuring consumption of gas and the like.

  Further, the information output device 100 is a gas consumption used in a gas water heater for auxiliary heating of hot water provided in the combined heat and power supply device, or a gas hot water supply device (not shown) installed in the home separately from the combined heat and power supply device. It has a hot water supply gas consumption measuring means 7 for measuring the gas consumption used or the gas consumption used for both hot water supply.

  Therefore, the measured value of the household total gas usage measuring means 5 is theoretically larger than the sum of the measured value of the power generation gas usage measuring means 6 and the hot water supply gas usage measuring means 7. This is because gas is used for cooking and other purposes in addition to power generation and hot water supply.

  In addition, the information output device 100 includes a domestic total water consumption measuring means 8 that measures the total amount of water consumed in the home, and a combined heat and power device water usage that measures the consumption of water supplied from the combined heat and power supply device. It has a measuring means 9 and a first integrated amount calculating means 10.

  The first integrated amount calculation means 10 includes a home total power consumption measuring means 1, a power purchase amount measuring means 2, a power sale amount measuring means 3, a power generation amount measuring means 4, a home total gas usage amount measuring means 5, and a power generation Gas usage measuring means 6, hot water gas usage measuring means 7, domestic total water usage measuring means 8, and cogeneration apparatus water usage measuring means 9 (hereinafter, when these measuring means are collectively shown, The integrated amounts of all the measured values of “each measuring means 1 to 9” are sequentially calculated.

  Furthermore, the information output device 100 outputs current date / time (time) data including at least year / month / date / time data, and inputs the current date / time (time) data from the time measuring means 11 to a predetermined time (for example, (1 minute, 5 minutes, 10 minutes, 15 minutes, 20 minutes, 30 minutes, 60 minutes, 2 hours), the accumulated amount calculated by the first accumulated amount calculating means 10 in combination with the date and time data is sequentially stored. Quantity storage means 12. Moreover, the information output device 100 has an operation unit 13 of a remote controller for a combined heat and power device installed indoors. The operation means 13 has a period designating means 14 for the user of the combined heat and power supply apparatus to designate an arbitrary period consisting of the starting date and time and the date and time interval.

  The information output apparatus 100 also includes an end point date and time calculation unit 15 that calculates an end point date and time from the start point date and time and the date and time interval specified by the period specifying unit 14, and an end point date and time and a start date and time calculated by the end point date and time calculation unit 15. The integrated amount reading means 16 for reading out the integrated amount from the integrated amount storage means 12 based on the date / time data.

  The second integrating means obtains the consumption amount between them by calculating the difference between the integrated amount at the end date and time read by the integrated amount reading means 16 and the integrated amount at the starting date and time, and the starting point to reach the consumed amount. Calculate the number of days that have elapsed since the date and time. Further, the second integrated amount calculation means 17 calculates a scheduled date on which an amount equivalent to the consumption amount is further consumed from the calculated consumption amount and the elapsed days.

  Further, the integrated amount output means 19 constitutes a part of the display means 18 of the remote controller for the combined heat and power unit installed indoors, and the integrated amount calculated by the second integrated amount calculating means 17, the number of elapsed days, Outputs the estimated date of reaching the consumption amount (displays the numerical value of the accumulated amount for any period directly or in a graph).

  The first integrated amount calculating means 10 includes a nonvolatile register (not shown) provided for each data to be measured and at least one adder (not shown). Each time the measurement value output from .about.9 is input, the input measurement value is added to the data held by the register, and the value of the register is updated with the integrated value, which is the sum, and output.

The important point here is that the first integration amount calculation means 10 continues to integrate the measurement values output from the respective measurement means 1 to 9 sequentially in a register provided for each data to be measured. The contents of the register are not erased at the milestones of the calendar, and are always accumulated from the installation to the life end (life of the combined heat and power device) in the life cycle of the combined heat and power device. As a result, since the configuration of the first integrated amount calculation means 10 becomes simple, it is obvious that quality reduction and cost reduction are achieved by reducing the number of parts.

  In this case, since the measured values are accumulated and stored in the register, there is a concern that the register bit length becomes long and difficult to realize. However, the data to be measured is the amount of power consumed in the home, the amount of power purchased from the power company, the amount of power sold to the power company, the amount of power generated by the combined heat and power unit, the total amount of gas consumed in the home, and the combined heat and power unit Gas consumption used for power generation, gas consumption used for hot water supply, all water consumption in the home, water consumption used by the combined heat and power unit, so it is naturally limited to a finite value It is obvious.

  Taking power consumption as an example, a standard household uses 300 kWh of electricity per month, so 10 kWh per day is used. Even if there is a household that uses 20 kWh per day, if the life cycle of a combined heat and power unit is 10 years, the power consumption in the life cycle is 73,000 kWh. Even if it is assumed that the second decimal place is measured and the 100-fold value is stored, it is only necessary to store up to 7,300,000 in the register. Therefore, if a 32-bit register is prepared, it is possible to store amounts of power, water, etc., and it is clear that storing these amounts can be realized sufficiently.

  The user can specify an arbitrary period with the period specifying means 14 by specifying the starting date and time and the number of days in the forward / reverse direction (for example, specifying the past two months from today, the past month from today, last month) (Designation of the first 10 days, designation of 10 days from April 2, 2009). However, it is possible to specify both the start date and time and the end date and time, or specify this month and last week, for example, April 2009, in accordance with the calendar.

  Next, the operation of the information output device 100 of the cogeneration device will be described. The home total power consumption measuring means 1 measures all the power consumption in the home. The power purchase amount measuring means 2 measures the power purchase amount from the electric power company. The power sales amount measuring means 3 measures the amount of power sold to an electric power company out of the power generated by the solar power generation system installed in the home. The power generation amount measuring means 4 measures the power generation amount generated by the combined heat and power supply device installed in the home.

  The household total gas consumption measuring means 5 measures the consumption of all city gas in the household. The power generation gas usage measuring means 6 measures the consumption of city gas used by the combined heat and power supply device for power generation. Gas consumption measuring means 7 for hot water supply is the gas consumption used in the gas water heater for auxiliary heating of the hot water provided in the combined heat and power supply, or the gas used in the gas hot water supply installed in the home separately from the combined heat and power supply Measure consumption or gas consumption used for both hot water supply.

  The household total water consumption measuring means 8 measures the consumption of all water in the household. The combined heat and power device water usage measuring means 9 measures the consumption of water used by the combined heat and power device.

  And the 1st integration amount calculation means 10 calculates sequentially the integration amount of the measured value by each measurement means 1-9.

On the other hand, the time measuring means 11 outputs current date / time (time) data including at least the year / month / date / time. The accumulated amount storage means 12 inputs the current date and time (time) data from the time measuring means 11 and predetermined time (for example, 1 minute, 5 minutes, 10 minutes, 15 minutes, 20 minutes, 30 minutes, Every 60 minutes, 2 hours), the integrated amount calculated by the first integrated amount calculating means 10 is sequentially stored in combination with the calculation date.

  The user of the combined heat and power supply device uses the operation means 13 of the remote control for the combined heat and power supply device installed indoors, and the power consumption in the home, the amount of power purchased from the power company, the amount of power sold to the power company, and the combined heat and power generation device generates power. Power generation, all gas consumption in the home, gas consumption used by the combined heat and power supply device, gas consumption used for hot water supply, all water consumption in the home, combined use of the combined heat and power device Select the information you want to know about water consumption. Further, the user designates the period for which the selected information to be known is desired by the period designation means 14 in the operation means 13 of the remote controller. At this time, the winner designates a setting value desired to know about the selected information by the setting value designation means 21 in the operation means 13 of the remote controller. This set value is the value that the selected information, that is, the consumption amount of gas or the like reaches.

  In order to simplify the explanation, a case where only the total domestic power consumption is displayed in FIG. 2 will be described as an example. In this example, the case where the user designates one month from April 11, 2010 as the designated period by the period designation unit 14 will be described. The accumulated amount storage means 12 combines the accumulated total amount of electric power used at home at the end of one day, which is the unit time, with the date, and calculates the amount of the period from January 1, 2010 to May 10, 2010. Remember every day.

  Next, the end point date and time calculating unit 15 calculates the end point date and time based on the starting point date and time specified by the period specifying unit 14. Here, the end date / time is calculated as one month from April 11, and the final end date / time is calculated as May 11, 2010.

  Next, the integrated amount reading unit 16 reads the integrated amount of the total electric power consumption at both the end point date and the starting point date calculated by the end point date calculating unit 15 from the integrated amount storage unit 12 based on the date information.

  Then, the second integrated amount calculating means 17 subtracts the integrated amount of the home total power consumption at the starting date and time from the integrated amount of the home total power consumption at the end point date and time read by the integrated amount reading means 16. Calculate the total power consumption in the home. Further, when the calculated total household power consumption reaches the delimiter consumption, the number of days elapsed from the previous time is calculated. Here, the delimiter consumption is a numerical value for dividing the power consumption in stages for each predetermined amount, and should be changed in conjunction with an arbitrary period designated by the user. In this embodiment, the delimiter consumption is set as a number that is a multiple of 100, such as 100 kwh or 200 kwh. Numbers are preferred. Further, a scheduled arrival date for the next predetermined power consumption is calculated based on the number of days elapsed from the starting date and time.

  Next, as shown in FIG. 3, the total power consumption in the home and the number of days elapsed in the arbitrary period (until the day before this year) calculated by the second integrated amount calculation means 17 are graphed and directly expressed. The output signal from the integrated amount output means 19 is displayed on the display means 18 of the remote controller of the cogeneration apparatus. In addition, the scheduled date of arrival at the next delimited consumption is displayed. In FIG. 3, the total power consumption in the home last month is shown by a dotted line in the graph. If this month's graph is above this dotted line, it means that the number of elapsed days is greater than the same household total power consumption, indicating that power consumption can be saved compared to last month. On the other hand, if it is below the dotted line, it can be seen that the same amount of power is consumed in a short period of time for the same total household power consumption, so this month's power consumption is increasing I understand that.

Therefore, the user does not judge whether or not he / she can save electricity because the total household power consumption per day is much smaller than the same day last month, but instead of determining whether or not he / she can save power, he / she can increase or decrease the power consumption in units of one month. I can grasp. As a result, it is possible to grasp the increase / decrease in the power consumption per month while suppressing the influence of climate change such as hot or cold, or an individual event such as a home party.

  Further, the user can specify the period in an arbitrary format, and the processing time of the CPU until data is displayed does not change depending on the format of specifying the period. Therefore, the user can see the amount of electricity consumed for a specified period not only in calendar units such as year, month, week, day, but also in an arbitrary format.

  Here, the explanation has been focused on the accumulation and display of all the consumption of electricity in the home, but in the combined heat and power system, when the electricity generated by the fuel cell or electricity exceeding the power generation is used, It can also be applied to the amount of power purchased, the amount of heat collected during power generation, the amount of gas used for power generation in the fuel cell, the amount of gas used in the backup heat source, the amount of hot water discharged from the combined heat and power supply device, and the like.

  Furthermore, the solar power generation system can be applied to the amount of power generated by solar cells and the amount of power sold to an electric power company. In the gas water heater, the gas consumption of the gas water heater can be expanded. In the electric water heater, the electricity consumption of the electric water heater can be expanded.

  With the above configuration, if the user designates an arbitrary period with the operation means 13, the data calculation start date and time and the calculation end date and time are determined from the period, the corresponding data is read, and the difference between them is read. By calculating, data corresponding to an arbitrary period can be obtained. Therefore, the user can see not only the calendar unit but also the data corresponding to that period in any period except the future and before the installation of the combined heat and power supply apparatus. Therefore, the user can view the data for an arbitrary period without limiting the period during which the data can be viewed, so you can freely change the period you want to compare and reduce the amount of energy consumed in the future. It becomes possible to see the results of awareness and efforts to reduce energy. Thus, the usability of the information processing apparatus of the thermoelectric generator is improved.

  Furthermore, it is possible to calculate the amount of consumption by reading the data of the start date and end date and taking the difference once, whatever the format of the specified period is whatever the format. There is no huge amount of calculation.

  In the prior art, data is stored in units of months, weeks, and days in the calendar, so if you want to display data that deviates from that unit, you need to repeat the calculation using the data in the calendar unit. Obviously you can't get. For example, in order to obtain consumption for the past month in the middle of the month, in the conventional example, the daily data for the past month must be read and summed 30 times or 31 times. In the embodiment, the data with the tags of the calculation start date and time and the calculation end date and time extracted from the arbitrary period are read, and if the difference is taken, the consumption amount of the arbitrary period is obtained.

  Thus, according to the information output device 100 of the cogeneration apparatus of the present embodiment, the start date / time is arbitrarily changed, and the start date / time and the end date / time of the comparison target can be changed even if the date / time is not limited to the calendar. Since it is only necessary to take the difference between the integrated amount contained in the two data and the date and time, the sum of the integrated amounts stored for each day is calculated as in the conventional example to calculate the energy consumption for any two days and hours. Obviously, it is easier than this, and the graph of consumption-elapsed days can be generated with a small amount of calculation.

Furthermore, by pointing the consumption and elapsed days specified by the user on a graph with consumption on the horizontal axis and elapsed days on the vertical axis, is the consumption in that period tending to save? It becomes clear at a glance whether it tends to be wasted. Judging from this graph, it is easy to know the trend of energy consumption (whether it tends to be conserved or wasted) regardless of the user's daily events or changes due to mechanism fluctuations. It is.

  In addition, regarding the numerical display or graph display of the integrated amount for an arbitrary period, a plurality of integrated numerical values or graphs for an arbitrary period may be arranged side by side for comparison.

  The information output device of the combined heat and power supply apparatus according to the present invention can be applied not only to a household combined heat and power supply apparatus but also to a commercial combined heat and power supply apparatus.
