Description

  The present invention relates to an information output device for a combined heat and power device that outputs information related to any of gas, power, and water in a household 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. 3 is a block diagram showing a conventional example described in Patent Document 1. In FIG.

  In FIG. 3, a measuring means 500 periodically measures the amount of gas and the amount of water and outputs a measured value. The integrating means 501 integrates the measured values. The calendar means 502 outputs time data while measuring time based on a calendar. The storage unit 503 stores the integrated value integrated by the integrating unit 501 and the time data output by the time measuring unit 502 in association with each other.

  The data stored in the storage unit 503 can display the usage value for each period to the user by displaying the integrated value together with the date and time on the display unit 504. The period-by-period integration management unit 505 instructs the storage unit 503 to store the time data and the integrated value in association with each other at a predetermined period, and also resets the integrated value and restarts the integration. Is responsible for directing.

  Normally, the integration unit 501 integrates the measurement value output from the measurement unit 500. However, when a reset & integration start signal is input from the period-based integration management unit 505, the integration value is once cleared to zero and zero. Restart the integration from. For example, when the integration management unit 505 for each period manages the integration data every day, a storage instruction is output to the storage unit 503 so as to store the integration value and the time data in association with each other at 24:00, Thereafter, the integration value of the previous day can be cleared to zero by outputting reset & integration start, and the integration of the day can be started by starting the re-integration.

  By repeating this operation every day (every time at 24:00), the amount of gas and water used every day can be stored in the storage means 503. That is, in this conventional example, the integrated value stored in the storage unit 503 is the amount of gas or water used in the period indicated by the time data. If the time data indicates the day, it is the amount of gas or electricity used every day, and if it indicates the month, it is the amount of gas or electricity used every month.

  With the above configuration, the accumulated value and time data are stored in association with each other for a predetermined period (year, month, day, etc.) in the calendar. It is possible to know the amount used) on the display means 504.

Japanese Patent No. 3061215

  However, the conventional configuration has the following problems. That is, in order to see the amount of usage for a predefined period (month, week, day), it is sufficient to read the data for the corresponding period from the storage device. Calculation is necessary and it is not possible to respond flexibly. For example, in order to see the usage for the past month in the middle of the month, the sum of the integrated values for each day corresponding to the past month must be calculated.

  Embodiments of an information output device for a combined heat and power device according to the present invention will be described below with reference to the drawings. Note that the present invention is not limited to the embodiments.

(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 method for calculating a usage amount in 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 of the combined heat and power supply apparatus of the present embodiment includes a home total power usage measuring means 1 that measures all the power usage in the home, and the amount of power purchased from the power company. Electric power purchase measuring means 2 from the electric power company to be measured, and electric power sales amount measuring means to the electric power company that measures the amount of electric power sold to the electric power company out of the electric power generated by the solar power generation system (not shown) installed in the home 3. A combined heat and power supply unit (not shown) installed in a household that uses city gas and water to generate electricity with a fuel cell, collects the heat generated during power generation, stores the hot water, and uses it for hot water supply The power generation amount measuring means 4 of the combined heat and power device for measuring the amount of power generated by the power generator, the domestic total gas usage measuring means 5 for measuring the usage amount of all city gas in the household, and the combined heat and power generation device for generating power For power generation to measure city gas consumption Used in a gas water heater for auxiliary heating of the hot water supply provided in the gas usage measuring means 6 and the combined heat and power supply device, or used in a gas hot water supply device (not shown) installed in the home separately from the combined heat and power supply device, or Gas usage measuring means 7 for measuring hot water used for both hot water supply, household total water usage measuring means 8 for measuring all water usage in the home, and combined heat and power supply Combined heat and power supply device water usage measuring means 9 for measuring the amount of water used by the apparatus, integrated amount calculating means 10 for sequentially calculating the integrated amount of the measured values by these measuring means 1 to 9, and at least the date The current date and time (time) data including the time, and the current date and time (time) data is input from the time measuring means 11 and predetermined time (for example, 1 minute, 5 minutes, 10 minutes, 15 minutes) 20 minutes, 30 minutes, 60 minutes The integrated amount storage means 12 for sequentially storing the integrated amount calculated by the integrated amount calculation means 10 every 2 hours) in combination with the calculation date and time, and one of the operation means 13 of the remote controller of the combined heat and power unit installed indoors A period designating means 14 for the user of the combined heat and power supply device to designate an arbitrary period, a starting point end point date and time calculating means 15 for calculating the starting point date and end point date and time of the arbitrary period specified by the period specifying unit 14; The integrated amount reading means 16 that reads the integrated amount of both the starting date and end time calculated by the starting point / end date / time calculating means 15 from the integrated amount storage means 12 based on the date / time information, and the end point date / time read by the integrated amount reading means 16 An arbitrary period integrated amount calculation means 17 for calculating an integrated amount for an arbitrary period by subtracting the integrated amount of the starting date and time from the integrated amount of the display, and a display means 1 for a remote controller of the cogeneration device installed indoors An arbitrary period integrated amount output means 19 that constitutes one of 8 and outputs the integrated amount of the arbitrary period calculated by the arbitrary period integrated amount calculation means 17 (the numerical value of the integrated amount of the arbitrary period is displayed directly or in a graph); Is provided.

  The integrated amount calculation means 10 includes a non-volatile register (not shown) provided for each data to be measured and at least one adder (not shown), and the measurement means 1 to 9 output the measurement. Each time a value is input, the data held in the register and the input measured value are added, 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 integrated amount calculating means 10 simply integrates the measured values output from the measuring means 1 to 9 into the registers provided for each data to be measured. The contents of the register are not cleared at the milestones of the calendar, and are always accumulated from the installation to the life end in the life cycle of the combined heat and power system. As a result, since the configuration of the integrated amount calculation means 10 becomes simple, it is obvious that the quality can be improved and the cost can be reduced 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 used 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 used in the home, and the combined heat and power unit Because it is the amount of gas used for power generation, the amount of gas used for hot water supply, the amount of water used in the home, the amount of water used by the combined heat and power unit, it is naturally limited to a finite value. It is obvious.

  Taking the amount of electric power used as an example, a standard household uses 270 kWh of electricity per month, but if there is a household that uses a maximum of 20 kWh per day, it will be 7,300 kWh per year and the life cycle of the combined heat and power system will be 10 If it is a year, 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, it is clear that if a 32-bit register is prepared, it can be saved and can be sufficiently realized.

  The user can specify an arbitrary period with the period specifying means 14, for example, according to the calendar, specifying this month, last week, specifying as of April 2009, starting date and time, and forward / reverse direction from there. (For example, the designation of the past two months from today, the designation of the past 10 months of today, the designation of the first 10 days of the previous month, the designation of 10 days from April 2, 2009), the starting date and end point It is a specification of both of the date and time.

  Next, the operation of the information output device of the cogeneration device of this embodiment will be described. The household total power consumption measuring means 1 measures all the household power usage. The power purchase amount measuring means 2 from the power company measures the power purchase amount from the power company. The electric power sales amount measuring means 3 for the electric power company measures the electric power sales amount to the electric power company out of the electric power generated by the solar power generation system installed in the home. The power generation amount measuring means 4 of the cogeneration device measures the amount of power generated by the cogeneration device installed in the home. The household total gas consumption measuring means 5 measures the usage of all city gas in the household. The power generation gas usage measuring means 6 measures the usage amount of city gas used by the combined heat and power supply device for power generation. The gas consumption measuring means 7 for hot water supply is used in a gas water heater for auxiliary heating of hot water provided in a combined heat and power supply device, or used in a gas hot water device installed in a home separately from the combined heat and power supply device, or Measure the amount of gas used for both hot water supplies. The household total water usage measuring means 8 measures the usage of all water in the household. The combined heat and power device water usage measuring means 9 measures the amount of water used by the combined heat and power device.

  Then, the integrated amount calculating means 10 sequentially calculates the integrated amounts of the measurement values obtained by the measuring means 1-9. On the other hand, the time measuring means 11 outputs current date / time (time) data including at least 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, The integrated amount calculated by the integrated amount calculating means 10 is stored in combination with the calculation date and time every 60 minutes, 2 hours).

  The user of the combined heat and power supply unit uses the remote control means 13 of the combined heat and power supply unit installed indoors to use power in the home, purchase power from the power company, sell power to the power company, and generate power from the combined heat and power supply unit. The amount of power generated, all the gas used in the home, the amount of gas used by the combined heat and power unit for power generation, the amount of gas used for hot water supply, the total amount of water used in the home, and the combined heat and power unit used Information to be known is selected from the amount of water used, and the period for which the selected information to be known is desired is designated by the period designation means 14 in the operation means 13 of the remote controller.

  Referring to the example of FIG. 2, the cumulative total amount of electricity used at home at the end of the date is combined with the date and the amount from January 1, 2010 to May 11, 2010 is stored in the cumulative amount storage means 10. In this state, the total power consumption in the home for the last 31 days up to the previous day is specified.

  Next, the start / end date / time calculating means 15 calculates the start date / time and end date / time of the arbitrary period (the last 31 days up to the previous day) specified by the period specifying means 14. In this case, the starting point / end date / time calculating means 15 calculates the starting point date / time as April 10, 2010, and calculates the end point date / time as May 11, 2010.

  Next, the integrated amount reading means 16 uses the total power consumption in the home for both the starting date / time (April 10, 2010) and the end date / time (May 11, 2010) calculated by the starting / ending date / time calculating means 15. Is read out from the integrated amount storage means 12 based on the date / time information. Then, the starting date and time (April 10, 2010) from the integrated amount of the total power consumption in the home at the end point date and time (May 11, 2010) read by the integrated amount reading means 16 by the arbitrary period integrated amount calculation means 17 By subtracting the integrated amount of the total electric power consumption in the home, the total electric power consumption (integrated amount) in the home for an arbitrary period (the last 31 days until the previous day) is calculated.

  Next, the total electric power consumption (integrated amount) in the home for the arbitrary period (the last 31 days up to the previous day) calculated by the arbitrary period integrated amount calculating means 17 is supplied to the remote controller of the combined heat and power unit by the arbitrary period integrated amount output means 19. The display unit 18 displays the numerical value directly or in a graph.

  The important point here is that the user can specify the period in an arbitrary format, and the time taken for the overhead until data is displayed does not change depending on the format for specifying the period. Therefore, the user can see the amount of electricity used for a specified period in an arbitrary format as well as a calendar unit such as year, month, week, and day.

  In addition, the user should use the electricity (electric power) consumption during the period of concern to determine whether to reduce the amount of energy used in the future with reference to the period, or whether power can be saved smoothly. Is possible.

  Here, the explanation has been focused on the accumulation and display of all the usage of electricity in the home. However, 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. The gas water heater can be used for gas usage of a gas water heater, and the electric water heater can be used for electricity usage of an electric water heater.

  As described above, when the point that this embodiment is superior is described again, if the user designates an arbitrary period, the calculation start date and time and the calculation end date and time are determined from the period, and the data corresponding to them is determined. Since the data corresponding to an arbitrary period can be obtained by calculating the difference between them, the user is not limited to the calendar unit, but in any period except for the future and before the installation of the combined heat and power unit. However, the data corresponding to the period can be viewed. So, the user can see the data for any period without being limited to the period in which the data can be viewed, so you can freely change the period you want to compare and reduce the amount of energy used in the future It becomes possible to see the result of the energy reduction efforts so far.

  In addition, the usage amount can be calculated by reading the data of the start date / time and the end date / time and taking the difference once, whatever the specified format of the arbitrary period is of any length. There is no huge amount of calculation.

  In the conventional example, data is saved 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 the amount used in 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 having the start date and time for calculation and the end date and time for calculation extracted from an arbitrary period as tags are read, and if the difference is taken, the usage amount for the arbitrary period is obtained.

  As described above, the information output device of the combined heat and power supply apparatus according to the present embodiment measures the total electric power consumption measuring means 1 for measuring all electric power consumption in the home and the amount of electric power purchased from the electric power company. Electricity purchase amount measuring means 2 from the electric power company and electric power sale amount measuring means 3 to the electric power company that measures the amount of electric power sold to the electric power company out of the electric power generated by the solar power generation system (not shown) installed in the home And a combined heat and power supply device (not shown) that is installed in a household and uses city gas and water to generate electricity with a fuel cell, collect the heat generated during power generation, store the heated hot water, and use it for hot water supply The power generation amount measuring means 4 of the combined heat and power supply device for measuring the amount of generated power, the household total gas consumption measuring means 5 for measuring the usage amount of all city gas in the household, and the combined heat and power supply device for generating power Power generation that measures the amount of city gas used Used in a gas water heater for auxiliary heating of the hot water supply provided in the combined heat and power supply device 6 or in a gas hot water supply device (not shown) installed in the home separately from the combined heat and power device, or , A hot water gas usage measuring means 7 for measuring the gas usage used for both of the hot water supply, a domestic total water usage measuring means 8 for measuring all the water usage in the home, and a thermoelectric Combined heat and power device water usage measuring means 9 for measuring the amount of water used by the co-feeding device, integrated amount calculating means 10 for sequentially calculating the integrated amount of the measurement values by these measuring means 1 to 9, and at least the year and month Timekeeping means 11 for outputting current date and time (time) data including date and time, and input of the current date and time (time) data from the timekeeping means 11 for a predetermined time (for example, 1 minute, 5 minutes, 10 minutes, 15 Min, 20 min, 30 min, 6 One of the integrated amount storage means 12 for sequentially storing the integrated amount calculated by the integrated amount calculating means 10 every minute, 2 hours) in combination with the calculation date and time, and one of the remote control operating means 13 for the combined heat and power unit installed indoors. And a period designating unit 14 for designating an arbitrary period by a user of the combined heat and power supply device, and a starting point end point date and time calculating unit 15 for calculating the starting point date and end point date and time of the arbitrary period specified by the period specifying unit 14; The integrated amount reading means 16 for reading out the integrated amount of both the starting date / time and the end date / time calculated by the starting point / end point date / time calculating means 15 from the integrated amount storage means 12 based on the date / time information, and the end point read by the integrated amount reading means 16 Arbitrary period integrated amount calculation means 17 for calculating the integrated amount of an arbitrary period by subtracting the integrated amount of the starting date and time from the integrated amount of date and time, and display means for the remote controller of the cogeneration device installed indoors An arbitrary period integrated amount output means 19 that outputs the integrated amount for an arbitrary period calculated by the arbitrary period integrated amount calculation means 17 (displays the numerical value of the integrated amount for the arbitrary period directly or in a graph). Is provided.

  In the above configuration, the integrated amount calculating means 10 sequentially calculates the integrated amount related to at least one of gas, electric power, and water, and the integrated amount storage means 12 is calculated by the integrated amount calculating means 10 every predetermined time. The integrated amount is sequentially stored in combination with the calculation date.

  When the user designates an arbitrary period using the period designating unit 14, the start point / end point date calculation unit 15 calculates the start point date / time and end point date / time of the arbitrary period designated by the period designation unit 14, and the integrated amount reading unit 16 uses the start point / end point. The integrated amount of both the start date and the end date calculated by the date calculation unit 15 is read from the integrated amount storage unit 12 based on the date information.

  Then, the integrated amount for the arbitrary period is calculated by subtracting the integrated amount for the starting date and time from the integrated amount for the end point date and time read by the integrated amount reading unit 16 by the arbitrary period integrated amount calculating unit 17, and the arbitrary period integrated amount output unit 19. Outputs the integrated amount of the arbitrary period calculated by the arbitrary period integrated amount calculating means 17.

  Therefore, the information output device of the combined heat and power supply apparatus according to the present embodiment can flexibly and quickly output an integrated amount related to at least one of gas, power, and water for an arbitrary period specified by the user using the period specifying means 14. The user can easily and quickly know the usage amount related to at least one of gas, electric power, and water supply for an arbitrary period specified by the period specifying means 14, so that comparison of energy usage is easy. It can be used to reduce energy consumption.
