Description

The present invention relates to a data transmission system using a computer to transmit data on carbon dioxide emission reductions created by using a plurality of energy-saving devices.

In recent years, efforts have been made to reduce emissions of greenhouse gases such as carbon dioxide. For example, in Japan, efforts are being made to contribute to the reduction of greenhouse gas emissions by utilizing the J-credit system. The J-credit system is a system in which the government certifies the amount of greenhouse gas emission reductions and absorption as "credits (emission rights)" through efforts such as the introduction of energy-saving equipment and forest management. This system is a system that integrates the domestic credit system and the offset credit system in a developmental manner.

Since the amount of carbon dioxide emissions can be reduced through the use of energy-saving equipment for home use, carbon dioxide credit certification can be obtained by performing procedures based on the J-credit system for the amount of reduction. However, in this case, the amount of credit to be authenticated is small, although the procedures for credit authentication are complicated. Therefore, each family does not go through the procedures individually.

In order to be able to effectively receive carbon dioxide credit certification even for the carbon dioxide that is reduced through the use of household energy-saving equipment with a small scale of carbon dioxide credits, the Green Linkage System operated by the government is being implemented. A club is created. In this Green Linkage Club, the amount of carbon dioxide emissions reduced by the use of energy-saving equipment owned by each household (individual), that is, the amount of carbon dioxide emission reduction created by the use of energy-saving equipment, is compiled and processed collectively. conduct. Therefore, the scale of carbon dioxide credits increases, and can be effectively used for carbon offsets and the like.

In addition, Patent Document 1 measures the amount of power generated by the use of fuel cells in a plurality of general households and small businesses, and calculates the amount of carbon dioxide emission reduction based on the total value of the measured power generation. A system configured to grant carbon dioxide credits based on carbon dioxide emission reductions is disclosed.

Further, Patent Document 2 discloses a system for aggregating the amount of carbon dioxide emission reductions from general households and the like without incurring a large cost, and making it possible to trade the carbon dioxide credits created thereby. According to this system, a device ID and power usage data are transmitted from an energy-saving electrical product in the home to the power usage meter. The data sent to the electricity usage meter is sent to the mobile terminal of the meter reader. The meter reader takes the mobile terminal back to the base and transmits these data from the mobile terminal to the server at the base. The server uses the received power usage data to calculate the amount of carbon dioxide emission reduction.

Further, Patent Literature 3 discloses a management device for constructing a system or mechanism for carbon dioxide credit transactions in anticipation of general households becoming targets of carbon dioxide credit transactions.

(Problems to be solved by the invention)
The operation of carbon dioxide credits (specifically, the application for approval of carbon dioxide credits) can be carried out by local governments and private companies. However, credit management institutions such as local governments and private companies are currently limited to a small number, such as Kobe City (Kobe _CO2 Bank) and Shizuoka Gas Co., Ltd. One of the reasons for this is the complexity of data collection until an application for approval of carbon dioxide credits, and the loss of the value of carbon dioxide credits. For example, the Kobe _CO2 Bank applies for approval of carbon dioxide credits based _on the amount of power generated by the fuel cell cogeneration system. The bank samples a plurality of users from registered users who have fuel cell cogeneration equipment. Next, a plurality of sampled users (hereinafter referred to as "sampling users") are asked to take a picture of the screen of the in-home remote controller that displays the power generation amount of their own fuel cell cogeneration system, and the power generation performance report is pasted with the picture. Have the form mailed to Kobe _CO2 Bank. Then, Kobe _CO2 Bank staff will collect the power generation data of each sampling user's fuel cell cogeneration system based on the results described in the power generation performance report mailed by each sampling user and the attached photo. collect. In this way, data collection is complicated because a plurality of manual operations are intervened for data collection. In addition, if there is a defect such as missing necessary information in the photograph taken by the sampling user, the photograph will be taken again, further complicating data collection. Furthermore, there may be sampling users who are uncooperative in such data collection, in which case it is necessary to encourage submission of photographs and reports, and the occurrence of such actions also increases the complexity of data collection.

In addition, when Kobe _CO2 Bank applies for carbon dioxide credits, in order to calculate (estimate) the aggregate value (total amount) of the overall carbon dioxide emission reduction from the data collected only from sampling users, the calculated aggregate value Data have uncertainty. Therefore, according to the rules of the J credit system, the value obtained by subtracting 10% from the total data is to be applied as a carbon dioxide credit. Therefore, the value of carbon dioxide credits to be applied for is damaged by that amount.

In this way, when managing carbon dioxide credits, there are the problems of the complexity of data collection and the problem of loss of the value of carbon dioxide credits, and the invention described in the above patent document solves these problems. No measures are shown.

The present invention provides a data transmission system that can simplify the collection of data for applying for carbon dioxide credits and transmit data so as to prevent or suppress loss of value. With the goal.

The present invention uses a computer configured to be able to communicate with a plurality of energy-saving devices, and provides data for transmitting data on the amount of carbon dioxide emission reduction created by using a plurality of energy-saving devices to a management server of a credit management institution. In the transmission system, the computer is specified by identification information acquisition processing for acquiring identification information data of a plurality of energy-saving devices registered in the management server from the management server, and identification information acquired by the identification information acquisition processing. from each of a plurality of specified energy-saving devices, and obtains individual usage data representing the usage of the specified energy-saving devices within a predetermined period, and associates the acquired individual usage data with the identification information data, Based on the evidence data storage processing to be stored and the individual usage data of each specific energy-saving device stored in the evidence data storage processing, a plurality of specified energy-saving devices between a predetermined measurement start date and a predetermined measurement end date Data aggregation processing for calculating the total amount of carbon dioxide emission reduction data created through the use of Aggregation to be sent to the management server together with the evidence data that associates the individual usage data of each specific energy-saving device or the accumulated value data with the identification information of each device stored in the evidence data storage process up to the date To provide a data transmission system capable of executing a data transmission process.

According to the present invention, a computer obtains identification information data of a plurality of energy-saving devices from a management server, thereby selecting a management server of a credit management institution from among a plurality of energy-saving devices configured to be able to communicate with the computer. A plurality of specific energy saving devices can be identified to which data should be sent to. In addition, the computer collects usage amount data of the specified plurality of specified energy-saving devices from each of the specified energy-saving devices from the predetermined measurement start date to the predetermined measurement end date, and collects the usage amount data Based on this, calculate the total amount of carbon dioxide emission reduction data created by using multiple specified energy-saving equipment. Then, the computer automatically transmits the data of the calculated total amount of carbon dioxide emission reduction to the management server together with the evidence data. In this way, data necessary for applying for carbon dioxide credits can be sent to the management server without human intervention, so that the user of the energy-saving equipment can take a photo and send the photo together with the report, as in the past. There is no need for mailing, and there is no need for credit management agency staff to collect data based on mailed reports and photographs. Therefore, it is possible to simplify the collection of data for applying for carbon dioxide credits, avoid human errors, and improve the accuracy of the data. In addition, data on the total amount of carbon dioxide emission reduction can be calculated by aggregating the data on all the specific energy-saving devices, and the data on the total amount is supported by evidence data. In other words, the calculated aggregate (total) amount of carbon dioxide emission reduction data is reliable and does not include uncertainty. Therefore, it is possible to apply for the total amount of the calculated carbon dioxide emission reduction amount as a carbon dioxide credit, and the value of the carbon dioxide credit is not impaired.

In the above invention, the identification information is information that can individually identify a plurality of specific energy-saving devices. Further, in the above invention, the "usage amount" of the specific energy-saving equipment is an amount that can express the amount of carbon dioxide emission reduction that is created. Therefore, the "amount used" may be the carbon dioxide emission reduction amount itself. Further, for example, when the specific energy-saving equipment is LED lighting, the amount of carbon dioxide emission reduction created is represented by the amount of power used. Therefore, in this case, the usage amount is the power usage amount. In addition, when the specified energy-saving equipment is a power generation device such as a fuel cell cogeneration device or a solar power generation device, the amount of carbon dioxide emission reduction is calculated based on the self-consumed power generation amount obtained by subtracting the reverse power flow rate from the power generation amount. Therefore, these amounts, that is, the power generation amount and the reverse flow rate, or the self-consumption power generation amount, correspond to the usage amount. Further, in the above invention, the "predetermined period", which is the interval at which the individual usage data is stored in the evidence data storage process, can be set arbitrarily. The "predetermined period" may be, for example, one day (that is, stored every day) as in the embodiment described later, or one week.

Further, the computer may be configured to execute the total data transmission process when a transmission request signal is input from the management server. According to this, the data of the total amount of carbon dioxide emission reduction can be transmitted to the management server together with the evidence data in a timely manner in response to a request from the credit management institution having the management server. In this case, the computer may be configured to execute the data aggregation process and the aggregation data transmission process when a transmission request signal is input from the management server.

In addition, the computer performs abnormality detection processing for detecting the occurrence of an abnormality that reduces the amount of carbon dioxide emission reduction from each of the plurality of specified energy-saving devices, and detects the abnormality if the abnormality is detected by the abnormality detection processing. and an abnormality notification process for notifying an abnormality of the specific energy-saving device that has been detected. According to this, by quickly detecting and reporting an abnormality that reduces the carbon dioxide emission reduction amount, the abnormality can be quickly repaired. For this reason, it is possible to suppress or prevent a decrease in the amount of carbon dioxide emission reduction due to the occurrence of an abnormality as much as possible. Therefore, it is possible to suppress the loss of the value of the carbon dioxide credit due to the reduction in the amount of carbon dioxide emission reduction caused by the occurrence of an abnormality in the energy saving device. In the above invention, the computer preferably notifies the abnormality in the abnormality notification process so that a person who takes action to repair the abnormality can recognize the abnormality. In this case, the computer detects an abnormality in a display device such as a remote controller connected to the specific energy-saving equipment, an information terminal (user terminal) of the user who has the specific energy-saving equipment, and a server or mobile terminal of the maintenance company of the specific energy-saving equipment. can be notified.

Also, the computer may be configured to be capable of periodically executing intermediate data transmission processing from a predetermined measurement start date to a predetermined measurement end date. In this intermediate data transmission process, usage amount intermediate data, which is an accumulated value of individual usage amount data stored in evidence data storage processing from a predetermined measurement start date to the present time, is calculated for each of a plurality of specific energy-saving devices. Use of multiple specified energy-saving devices from the specified measurement start date to the current time, based on the usage amount intermediate data calculation processing and the usage amount intermediate data of each specific energy-saving device calculated by the usage amount intermediate data calculation processing and an intermediate total amount calculation process for calculating intermediate total amount data, which is data of the total amount of carbon dioxide emission reduction created by the method, and an intermediate total amount transmission process for transmitting the usage amount intermediate data and the intermediate total amount data. According to this, intermediate data of the total amount of carbon dioxide emission reduction (intermediate total amount data) is periodically transmitted to the management server, and the usage amount intermediate data is used as evidence data, for example, a remote control device connected to a specific energy saving device or a specific By transmitting to the user terminal of the user having the energy-saving device, the transmission history is saved as backup data. Therefore, after that, for example, if communication between the computer and each specified energy-saving device is interrupted due to some kind of communication failure and the computer cannot grasp the usage status of the specified energy-saving device, the interim total amount data and Carbon dioxide credits can be applied for using the evidence data (intermediate usage data).

Also, the specific energy-saving equipment may be a fuel cell cogeneration system. In this case, the computer performs power usage status acquisition processing for acquiring the power usage status in the home of the user who has the fuel cell cogeneration system, and power generation status acquisition process for acquiring the power generation status of the fuel cell cogeneration system owned by the user. , advice information transmission processing for creating advice information that will increase the amount of carbon dioxide emission reduction based on the power usage status and power generation status, and sending the created advice information. good. According to this, by providing advice information to the user of the fuel cell cogeneration system, it is possible to create a greater amount of carbon dioxide emission reduction. As a destination of the advice information to be sent in the advice information sending process, a remote control device connected to the fuel cell cogeneration system or users of the fuel cell cogeneration system can be exemplified. can.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an overview of a system to which a data transmission system according to this embodiment is applied. As shown in FIG. 1, this system includes a device group 10 consisting of energy-saving devices possessed by a plurality of users, a credit management agency (local government 20) such as a local government, a credit certification agency 30, and a credit buyer 40 such as a company. , and a support server 50 . It should be noted that the plurality of energy-saving devices constituting the device group 10 are energy-saving devices for home use, such as those installed in ordinary homes. In this embodiment, the fuel cell cogeneration device 11 is exemplified as an energy-saving device, but other energy-saving devices for home use, such as a solar power generation device, or electrical products recommended as energy-saving products, may also be used.

The fuel cell cogeneration system 11 generates power using fuel and oxygen, and generates heat along with the power generation. The amount of carbon dioxide emitted per unit power generation amount when power is generated using this fuel cell cogeneration device 11 is the amount of carbon dioxide emitted per unit power generation amount when a system power supply such as a commercial power supply generates power. less than quantity. Therefore, the more the power generated by the fuel cell cogeneration device 11 is used instead of the system power supply, that is, the more it is used as self-consumed power, the more the carbon dioxide emission is reduced, that is, the carbon dioxide emission reduction created. amount can be increased.

The fuel cell cogeneration system 11 is operated in either a rated operation in which the generated power is constant or a load following operation in which the generated power follows the domestic power consumption (power used in the user's home). In rated operation, the fuel cell cogeneration system 11 always generates power at the rated power (for example, 700 W) except during maintenance. On the other hand, in the case of load following operation, power is generated so as not to purchase power from the grid power supply for home use power below the rated power (for example, 700 W). In either operation method, when the domestic power consumption exceeds the rated power, the excess power is purchased from the grid power supply. Also, during rated operation, if the power used in the home is less than the rated power, the difference between the generated power (rated power) and the power used in the home is sold as surplus power. In this case, the power to be sold reversely flows through the system power supply. On the other hand, in the case of load following operation, surplus power does not occur, so reverse power flow of generated power does not occur.

Of the power generated by the fuel cell cogeneration system 11, the power that contributes to the reduction of carbon dioxide emissions is the power consumed at home, that is, the self-consumed generated power. Therefore, when the fuel cell cogeneration system 11 is in rated operation, the self-consumed generated power is the generated power minus the sold power (that is, the reverse flow power). On the other hand, when the fuel cell cogeneration system 11 is in load-following operation, the reverse flow power is 0, so all the generated power is self-consumed generated power.

Each user who has the fuel cell cogeneration device 11 constituting each device group 10 is a person who lives in the municipality 20 in this embodiment. Also, each user purchases the fuel cell cogeneration system 11 and performs a predetermined procedure with the local government 20, and subsidies are provided by the local government 20. FIG. Each user transfers the right based on the amount of carbon dioxide emission reduction created by using the fuel cell cogeneration system 11, that is, the right of the carbon dioxide credit to the local government 20 in return for receiving the subsidy from the local government 20. Then, the municipality 20 applies to the credit certification body 30 for approval of carbon dioxide credits based on the amount of carbon dioxide emission reduction created by the use of the fuel cell cogeneration system 11 of each user. The credit certification agency 30 verifies and deliberates the documents related to the authorization application, approves the carbon dioxide credits, and gives the approved carbon dioxide credits to the municipality 20 . It should be noted that a gas company or the like entrusted by the local government 20 may perform the operations of the credit management institution.

The municipality 20 sells the carbon dioxide credits given by the credit certification agency 30 to the credit buyer 40 by carbon offset or the like. Credit buyers 40 are preferably businesses within municipality 20, for example. As a result, the municipality 20 obtains profits from selling the carbon dioxide credits. By using the sales profit obtained in this way to subsidize users, it is possible to continuously promote the popularization of the fuel cell cogeneration system 11 and the accompanying reduction in carbon dioxide emissions.

The municipality 20 has a management server 21 . This management server 21 has a management database, and in this management database, the equipment manufacturing numbers of all the fuel cell cogeneration systems 11 to which subsidies are provided are listed for the users of each fuel cell cogeneration system 11. It is stored in a state associated with information. The device serial number corresponds to the identification information of the present invention. By storing this information in the management database, each fuel cell cogeneration device 11 of the user in the municipality 20 (in FIG. 1, the fuel cell cogeneration device 11 constituting the device group 10) is registered in the management server 21. be.

The support server 50 corresponds to the computer of the present invention. The support server 50 stores data necessary when the municipality 20 applies for a carbon dioxide credit to the credit certification body 30 based on the amount of carbon dioxide emission reduction created by using the fuel cell cogeneration device 11 that constitutes the device group 10. is provided to aggregate the collected data and transmit the aggregated data to the management server 21 . The support server 50 may be, for example, a computer owned by the manufacturer of the fuel cell cogeneration system 11 .

The support server 50 includes an arithmetic unit 51 , a storage unit 52 and a communication unit 53 . The calculation unit 51 is configured to implement various functions by executing each process described later. The storage unit 52 stores each process executed by the calculation unit 51, information such as a database required when the calculation unit 51 executes each process, values calculated by executing each process, and the like. Further, in this storage unit 52, the contact information of the user who owns the fuel cell cogeneration system 11 constituting the device group 10 is stored (registered). A user's contact information is, for example, an e-mail address of a user terminal such as a personal computer or a smartphone owned by the user. The communication unit 53 has a function of external communication.

The support server 50 is communicably connected to each of the plurality of fuel cell cogeneration devices 11 and the management server 21 of the local government 20 . FIG. 2 is a schematic diagram showing the state of connection between a plurality of fuel cell cogeneration devices, the support server 50, and the management server 21. As shown in FIG. As shown in FIG. 2, the fuel cell cogeneration system 11 has a communication function and is configured to be connectable to the Internet via a remote control device 12 and a wireless router 13 in the home where it is installed. Also, the support server 50 is configured to be connectable to the Internet via its communication unit 53 . Therefore, the plurality of fuel cell cogeneration devices 11 and the support server 50 are configured to be able to communicate via the Internet. In this embodiment, the fuel cell cogeneration system 11 is connected to the Internet via the remote control device 12 and the wireless router 13. However, the communication device installed in the fuel cell cogeneration system 11 is connected to the support server 50. A method of connecting to the Internet is also feasible. The support server 50 is also communicably connected to the fuel cell cogeneration system 11 that constitutes the device group 10 and the fuel cell cogeneration system 11 other than the fuel cell cogeneration system 11 that constitutes the device group 10 . . For convenience of explanation, among all the fuel cell cogeneration devices 11 connected to the support server 50, the fuel cell cogeneration devices 11 constituting the device group 10, that is, the fuel cell cogeneration devices registered in the management server 21 are It is called a specific fuel cell cogeneration system 11 . This specific fuel cell cogeneration system 11 corresponds to the specific energy saving device of the present invention.

Information data related to the operating state of the fuel cell cogeneration system 11 is constantly input to the support server 50 together with the device serial number via the communication function. Thereby, each fuel cell cogeneration device 11 is monitored by the support server 50 . Therefore, the support server 50 constantly grasps the power generation state of each fuel cell cogeneration device 11 .

In addition, the remote control device 12 in each user's home is configured to receive the amount of electric power used in the home. Therefore, the support server 50 can acquire the amount of electric power used in each user's home and the state of electric power use (for example, the amount of electric power used for each time slot) from the remote control device 12 in each home.

The support server 50 and the management server 21 are linked by an API (Application Programming Interface). Through this API linkage, the support server 50 can acquire the device manufacturing number of each fuel cell cogeneration device 11 stored in the management database of the management server 21 . FIG. 3 is a flow chart showing the flow of a device manufacturing number acquisition processing routine executed by the computing unit 51 so that the support server 50 acquires the device manufacturing number of each fuel cell cogeneration device 11 . This routine is periodically executed at predetermined intervals. When this routine is activated, the computing unit 51 accesses the management database of the management server 21 via the communication unit 53 in step 11 of FIG. 3 (hereinafter step is abbreviated as S). Next, all the device serial numbers in the management database are acquired (S12), and the acquired device serial numbers are stored in the device serial number database of the storage unit 52. FIG. After that, the calculation unit 51 terminates this routine. The equipment manufacturing number acquisition process (identification information acquisition process) described above is periodically executed by the computing unit 51, so that the equipment manufacturing number of the specific fuel cell cogeneration device 11 is stored in the equipment manufacturing number database of the storage unit 52. . By acquiring the device manufacturing number of the specific fuel cell cogeneration system 11 registered in the local government 20, the support server 50 can access all the fuel cell cogeneration systems communicably connected thereto. 11, a specific fuel cell cogeneration system 11 registered with the local government 20 can be specified. In other words, the specific fuel cell cogeneration device 11 is specified by the device serial number acquired by the device serial number acquisition process. The equipment manufacturing number acquisition process shown in FIG. 3 corresponds to the identification information acquisition process of the present invention. If the API link between the support server 50 and the management server 21 is not possible, the municipality 20 creates a list of the device manufacturing numbers of the specific fuel cell cogeneration device 11, sends an email to the support server 50, and stores the list in the support server 50. can also

In addition, the support server 50 stores data (individual usage amount data) of the daily power generation amount and the daily reverse power flow rate, which are the daily usage amounts of the plurality of fuel cell cogeneration devices 11 including the specific fuel cell cogeneration device 11. These acquired data are stored in the device-by-device evidence database of the storage unit 52 . For this purpose, the computing unit 51 of the support server 50 executes evidence data storage processing. FIG. 4 is a flow chart showing the flow of the evidence data storage processing routine executed by the calculation unit 51. As shown in FIG. This routine is repeatedly executed at predetermined short intervals. When this routine is activated, the computing unit 51 first determines whether or not the current time is a predetermined time (for example, 0:00 am) in S21 of FIG. If the current time is not the predetermined time (S21: No), the computing section 51 terminates this routine. On the other hand, if the current date and time is the predetermined time (S21: Yes), the calculation unit advances the process to S22.

In S22, the calculation unit 51 calculates the daily power generation amount E1, which is the amount of power generated by the fuel cell cogeneration device 11 from 0:00 a.m. to 23:59 on the previous day, and A daily reverse flow rate F1, which is the amount of power that reversely flows to the system power supply, is acquired for each device, that is, from each fuel cell cogeneration device 11 . In this case, the control unit in each fuel cell cogeneration device 11 sends the data of the daily power generation amount E1 and the daily reverse flow rate F1 of the previous day to the support server 50 together with the device manufacturing number at or before the predetermined time in S21. configured to transmit. Therefore, in S22, the support server 50 receives the data transmitted as described above, identifies the device manufacturing number based on the received data, and specifies the fuel cell cogeneration device 11 having the identified device manufacturing number. The data of the daily power generation amount E1 and the data of the daily reverse power flow rate F1 are acquired. The data of the daily power generation amount E1 and the data of the daily reverse flow rate F1 correspond to the individual usage amount data of the present invention.

Next, the calculation unit 51 advances the process to S23, and stores the data of the daily power generation amount E1 and the data of the daily reverse flow rate F1 acquired in S22 in the device-specific evidence database. FIG. 5 is a diagram showing an example of an evidence database for each device. As shown in FIG. 5, in the equipment-specific evidence database, data on the daily power generation amount E1 and the data on the daily reverse flow rate F1 of the fuel cell cogeneration system 11 are continuously stored every day for each equipment serial number. be. In S23, the calculation unit 51 stores the data of the previous day's daily power generation amount E1 and the data of the daily reverse flow rate F1 acquired in S22 in association with the corresponding device manufacturing number and the corresponding date. After that, the calculation unit 51 terminates this routine. By executing the evidence data storage process shown in FIG. Acquire individual usage data (daily power generation E1 data and daily reverse power flow rate F1 data) representing the usage amount (power generation amount, reverse power flow rate) of the specific fuel cell cogeneration device 11 within (one day) , the obtained individual usage amount data is associated with the device manufacturing number data and stored in the device-by-device evidence database on a daily basis.

In addition, the calculation unit 51 periodically transmits the intermediate data of the carbon dioxide emission reduction amount and its evidence data by periodically executing the intermediate data transmission process from the predetermined measurement start date to the predetermined measurement end date. send to FIG. 6 is a flow chart showing the flow of the intermediate data transmission processing routine executed by the calculation unit 51. As shown in FIG. This routine is repeatedly executed at predetermined short intervals. When this routine is activated, the computing unit 51 first determines in S31 of FIG. 6 whether or not the current date and time is the first predetermined time of the week (for example, 0:00 am). If the current date and time is not the first predetermined time of the week (S31: No), the calculation unit 51 terminates this routine. On the other hand, if the current date and time is the first predetermined time of the week (S31: Yes), the calculation unit 51 advances the process to S32.

In S32, the calculation unit 51 selects a plurality of specific fuel cell cogeneration systems specified by the device serial number acquired in the device serial number acquisition process (that is, specified by the device serial number stored in the device serial number database). For each of the devices 11, the data of the daily power generation amount E1 stored by the evidence data storage process from the predetermined measurement start date to the present time, that is, the data of the daily power generation amount E1 from the measurement start date to the last day of the previous week are summed up. Then, the cumulative intermediate power generation amount E2 is calculated. Furthermore, in S32, the calculation unit 51 calculates the daily reverse power flow rate stored in the device-specific evidence database from the predetermined measurement start date to the current time (the last day of the previous week) for each of the plurality of specific fuel cell cogeneration devices 11. The data of F1 are added to calculate the accumulated intermediate reverse flow rate F2.

Next, the calculation unit 51 advances the process to S33. In S33, the calculation unit 51 calculates the specific fuel cell cogeneration system 11 for each of the plurality of specific fuel cell cogeneration devices 11 based on the data of the cumulative intermediate power generation amount E2 and the data of the cumulative intermediate reverse power flow rate F2 calculated in S32. A cumulative intermediate carbon dioxide emission reduction amount C2, which is the carbon dioxide emission reduction amount created by the cogeneration device 11 from the measurement start date to the present time, is calculated. In this case, the cumulative intermediate carbon dioxide emission reduction amount C2 is calculated by substituting the cumulative intermediate self-consumed power generation amount G2 obtained by subtracting the cumulative intermediate reverse power flow rate F2 from the cumulative intermediate power generation amount E2 into a predetermined conversion formula. can be done.

Subsequently, the calculation unit 51 advances the process to S34. In S34, the calculation unit 51 adds up the data of the cumulative intermediate carbon dioxide emission reduction amount C2 calculated for each specific fuel cell cogeneration device 11 in S33 to calculate the intermediate total carbon dioxide emission reduction amount C3.

Next, the calculation unit 51 advances the process to S35, and the data of the cumulative intermediate power generation amount E2 and the data of the cumulative intermediate reverse power flow rate F2 for each specific fuel cell cogeneration device 11 calculated in S32 and S33, The data of the carbon dioxide emission reduction amount C2 is transmitted to the user of the corresponding specific fuel cell cogeneration system 11. In this case, the computing unit 51 sends these messages to the mail address of the user terminal of each user registered in the support server 50 or to the remote control device 12 connected to the specific fuel cell cogeneration device 11 of that user. Data can be sent.

Further, the calculation unit 51 advances the process to S<b>36 and transmits the intermediate total carbon dioxide emission reduction amount C<b>3 calculated in S<b>34 to the management server 21 . After that, the calculation unit 51 terminates this routine.

By executing the above-described intermediate data transmission processing by the calculation unit 51, the individual usage amount data ( Intermediate usage data (data of cumulative intermediate power generation E2 and data of cumulative intermediate reverse flow F2) representing the cumulative value of daily power generation E1 and daily reverse flow It is calculated for each generation device 11 (S32). In addition, based on the calculated intermediate usage amount data of each of the specified fuel cell cogeneration devices 11, from the measurement start date to the present time (in this embodiment, until the last day of the previous week), a plurality of specified fuel cell cogeneration devices 11 (data of intermediate total carbon dioxide emission reduction C3) is calculated (S34). Then, the data of the calculated intermediate total carbon dioxide emission reduction amount C3 is transmitted to the management server 21 every week (S36), and the usage amount intermediate data, which is the evidence data, is sent to the user of each specified fuel cell cogeneration device 11 weekly. is sent every time (S36). This intermediate data transmission process may be performed weekly, monthly, or daily as described above.

In addition, the calculation unit 51 of the support server 50 aggregates the data of the carbon dioxide emission reduction amount created from the predetermined measurement start date to the predetermined measurement end date by executing the aggregation process. It is configured to be able to transmit data to the management server 21 . FIG. 7 is a flow chart showing the flow of the tallying processing routine executed by the computing unit 51. As shown in FIG. This routine is repeatedly executed at predetermined short intervals. When this routine is activated, the calculation unit 51 determines in S41 of FIG. 7 whether or not a data request signal has been input from the management server 21 after a predetermined measurement end date. This data request signal is transmitted from the management server 21 to the support server 50 by, for example, an operator of the management server 21 inputting a predetermined command to the management server 21 when the municipality 20 requests aggregated data on the amount of carbon dioxide emission reduction. sent to.

If the calculation unit 51 determines in S41 that the data request signal has not been input (S41: No), it ends this routine. On the other hand, when determining that the data request signal has been input (S41: Yes), the calculation unit 51 advances the processing to S42.

In S42, the calculation unit 51 refers to the device-specific evidence database, and sums and accumulates the daily power generation E1 from the predetermined measurement start date to the predetermined measurement end date for each of the specific fuel cell cogeneration devices 11. A power generation amount E3 is calculated. Next, in S43, the calculation unit 51 refers to the device-specific evidence database, and calculates the daily reverse flow rate F1 from the predetermined measurement start date to the predetermined measurement end date for each of the specific fuel cell cogeneration devices 11. are added to calculate the cumulative reverse flow rate F3.

Next, the calculation unit 51 advances the process to S44, adds up the cumulative power generation E3 calculated for each of the specific fuel cell cogeneration devices 11, and calculates the total power generation E4 from the measurement start date to the measurement end date. Furthermore, the cumulative reverse power flow rate F3 calculated for each specific fuel cell cogeneration device 11 is summed up to calculate the total reverse power flow rate F4 from the measurement start date to the measurement end date.

Subsequently, the calculation unit 51 advances the process to S45, and calculates the total self-consumed power generation amount G4 by subtracting the total reverse power flow rate F4 from the total power generation amount E4. Further, the calculation unit 51 advances the process to S46, and based on the total self-consumed power generation amount G4, carbon dioxide emissions that are the total amount of carbon dioxide emission reduction created from the predetermined measurement start date to the predetermined measurement end date A total emission reduction amount C4 is calculated. The processing from S42 to S46 corresponds to the data aggregation processing of the present invention.

Next, the calculation unit 51 advances the process to S<b>47 and transmits the data of the carbon dioxide emission reduction total amount C<b>4 and its evidence data to the management server 21 . Here, the evidence data to be transmitted to the management server 21 in S47 includes the data of the cumulative power generation amount E3 and the data of the cumulative reverse power flow rate F3 calculated for each of the specific fuel cell cogeneration devices 11 in S42 and S43, and the This data is associated with the manufacturing number of the specific fuel cell cogeneration system 11 that is the object of data calculation. After that, the calculation unit 51 terminates this routine. The process of S47 corresponds to the total data transmission process of the present invention.

Based on the individual usage amount data (daily power generation amount E1 and daily reverse flow rate F1) of each specific fuel cell cogeneration device 11 stored in the evidence data storage process, the calculation unit 51 executes the above-described aggregation process. Data of the total amount of carbon dioxide emission reduction created by using a plurality of specified fuel cell cogeneration devices 11 from the measurement start date to the measurement end date (data of total carbon dioxide emission reduction C4) is calculated. be done. Data on the calculated total amount of carbon dioxide emission reduction is automatically transmitted from the support server 50 to the management server 21 together with the evidence data. Based on the data sent to the management server 21, the municipality 20 can create documents required for carbon dioxide credit authentication. In this manner, data necessary for carbon dioxide credit authentication is automatically transmitted from the support server 50, so that collection and totalization of these data are not troublesome. That is, data collection can be simplified. In addition, the data of the total carbon dioxide emission reduction amount C4 can be calculated by aggregating the data of all the specific fuel cell cogeneration devices 11, and the data is supported by the evidence data. In other words, the data of the calculated total carbon dioxide emission reduction amount C4 is reliable and does not include uncertainty. Therefore, all of the calculated carbon dioxide emission reduction total amount C4 can be applied as a carbon dioxide credit, and the value of the carbon dioxide credit is not lost.

Further, according to the present embodiment, by executing the intermediate data transmission process, the calculation unit 51 periodically transmits data of the cumulative intermediate power generation amount E2, data of the cumulative intermediate reverse flow rate F2, cumulative intermediate carbon dioxide emissions, The data of the reduction amount C2 is transmitted to the user terminal of the user of each specific fuel cell cogeneration device 11, and the data of the intermediate total carbon dioxide emission reduction amount C3 is transmitted to the management server 21. Thereby, the transmission history of each data is stored in the user terminal and the management server 21 as backup data. Therefore, when communication between the support server 50 and each specific fuel cell cogeneration device 11 is cut off due to some kind of communication failure after that, and the power generation state of the specific fuel cell cogeneration device 11 cannot be grasped on the support server 50 side. , using the data of the intermediate total amount of carbon dioxide emission reduction C3 and its evidence data (the data of the cumulative intermediate power generation amount E2 and the data of the cumulative intermediate reverse flow rate F2) transmitted so far, it is possible to apply for carbon dioxide credits. can.

Further, according to the present embodiment, when a transmission request signal is input from the management server 21, the aggregation process is executed, and the data of the carbon dioxide emission reduction total amount C4 is transmitted to the management server 21 together with the evidence data. It is configured. Therefore, these data can be transmitted in a timely manner in response to a request from the municipality 20. FIG.

Further, the calculation unit 51 is configured to be able to notify the occurrence of an abnormality that causes a reduction in the power generation amount of the specific fuel cell cogeneration device 11, that is, an abnormality that causes a reduction in the amount of carbon dioxide emission reduction (carbon dioxide credit). It is FIG. 8 is a flow chart showing the flow of an abnormality notification processing routine executed by the calculation unit 51 to notify the occurrence of such an abnormality. This routine is repeatedly executed at predetermined short intervals. When this routine is activated, the calculation unit 51 determines in S51 of FIG. 8 whether or not an abnormal signal from any of the specific fuel cell cogeneration devices 11 has been detected. If no abnormal signal has been detected (S51: No), the computing section 51 terminates this routine. On the other hand, when an abnormal signal is detected (S51: Yes), the calculation unit 51 advances the processing to S52. Each fuel cell cogeneration device 11 is configured to output an abnormality signal represented by an error code that can determine the content of the abnormality to the support server 50 when an abnormality occurs.

In S52, the calculation unit 51 determines whether or not the abnormality signal detected in S51 is an abnormality signal representing a specific abnormality. Here, the specific anomaly means an anomaly that causes a decrease in the power generation amount of the fuel cell cogeneration system 11 (an anomaly that causes a decrease in the carbon dioxide emission reduction amount). For example, if a current sensor that measures the current of the generated power fails, power generation by the fuel cell cogeneration system 11 stops. When power generation stops, the generated power decreases. Therefore, failure of the current sensor is a specific anomaly. Further, if the air blower breaks down, the oxygen required for power generation cannot be supplied, resulting in a decrease in power generation capacity. As a result, it becomes impossible to obtain the necessary generated power, and the generated power decreases. Air blower failure is therefore also a specific anomaly. What kinds of abnormalities are specific abnormalities are stored in advance in the storage unit 52 of the support server 50 . Therefore, in S52, the calculation unit 51 can determine whether or not there is a specific abnormality based on the type of abnormality indicated by the abnormality signal. The process of S52 corresponds to the abnormality detection process of the present invention.

If it is determined in S52 that the abnormality signal is not an abnormality signal representing a specific abnormality (S52: No), the calculation section 51 terminates this routine. On the other hand, when it is determined in S52 that the abnormal signal is an abnormal signal representing a specific abnormality (S52: Yes), the calculation unit 51 advances the processing to S53. In S53, the calculation unit 51 identifies the equipment manufacturing number of the specific fuel cell cogeneration system 11 that has output the abnormal signal. Next, in S54, the calculation unit 51 notifies the specified fuel cell cogeneration device 11 side of the specified device manufacturing number of the abnormality. In this case, the abnormality may be displayed on the display of the in-home remote control device 12 connected to the specified fuel cell cogeneration device 11 having the specified device serial number to notify the user in the home of the abnormality. The user in the home may be notified of the abnormality by emitting a sound from the remote control device 12 . Further, the user terminal of the user of the specified fuel cell cogeneration device 11 having the specified device serial number may be notified of the abnormality by e-mail. Furthermore, when the server of the maintenance company of the specified fuel cell cogeneration device 11 with the specified equipment serial number and the support server 50 are configured to be able to communicate with each other, the server of the maintenance company may be notified of the abnormality. The process of S54 corresponds to the abnormality notification process of the present invention. After announcing the abnormality in S54, the calculation unit 51 terminates this routine.

By executing the above-described anomaly notification processing by the calculation unit 51 and quickly detecting and notifying the specific anomaly, the specific anomaly can be quickly repaired. Therefore, it is possible to minimize or prevent a reduction in the carbon dioxide emission reduction amount due to a reduction in the power generation amount due to the occurrence of the specific abnormality. Therefore, it is possible to suppress the loss of the value of the carbon dioxide credit due to the reduction in the carbon dioxide emission reduction amount due to the occurrence of the specific abnormality of the specific fuel cell cogeneration system 11 .

Further, the calculation unit 51 is configured to be able to provide advice information for maximizing the power generated by the specific fuel cell cogeneration device 11 (specifically, the generated power for self-consumption). FIG. 9 is a flow chart showing the flow of an advice information providing processing routine executed by the calculation unit 51 to provide advice information. This routine is periodically executed at predetermined time intervals. When this routine is activated, the calculation unit 51 selects one of the users of the specific fuel cell cogeneration system 11 in S61 of FIG. Next, in S62, the calculation unit 51 acquires the home power usage status of the selected user for a predetermined period (for example, one week) from the in-home remote control device 12 (power usage status acquisition process). Next, in S63, the calculation unit 51 acquires the power generation status of the specific fuel cell cogeneration device 11 for the predetermined period from the indoor remote control device 12 (power generation status acquisition process).

Subsequently, the calculation unit 51 calculates a time zone during the day when the purchased power is high (S64). In this case, the calculation unit 51 first calculates the average transition of the home power consumption for one day from the home power usage status for one week acquired in S62, and then calculates the average transition of the power consumption for one week acquired in S63. From the power generation situation, calculate the average transition of the power generation amount for one day. Next, by comparing the average transition of domestic power consumption for the day with the average transition of the amount of power generated for the day, the average transition of purchased power for the day is calculated. The purchased power can be obtained by subtracting the amount of power generated from the domestic power consumption during the same time period. Then, from the calculated average transition of the purchased power for one day, a period of time when the purchased power is high is calculated.

Next, the calculation unit 51 calculates the time periods during the day in which the indoor power consumption is less than the rated power of the specific fuel cell cogeneration system 11 (S65). Subsequently, the calculation unit 51 creates advice information (S66). For example, if the time period during which a large amount of purchased power is purchased in a day is from 8:00 to 9:00 and the time period in which the domestic power consumption is less than the rated power is from 4:00 to 6:00, the advice information is "8 Refrain from using electricity from 12:00 to 9:00 and use it from 4:00 to 6:00." After creating the advice information, the calculation unit 51 transmits the created advice information to the remote control device 12 to which the specific fuel cell cogeneration device 11 of the target user is connected (S67). As a result, the advice information is displayed on the display of the remote control device 12 and provided to the user.

Next, the calculation unit 51 advances the process to S78 and determines whether or not there is a user who has not yet selected. If there is a user who has not yet selected (S78: No), the calculation unit returns the process to S71 and repeats the processes after S71. On the other hand, if there is no user who has not yet selected (S78: Yes), the calculation unit 51 terminates this routine.

In order to maximize self-consumed power generation for the user having each specific fuel cell cogeneration device 11 based on the power usage status and power generation status by executing the advice information provision process described above by the calculation unit 51 advice information, in other words, advice information that will increase the amount of carbon dioxide emission reduction created by using the specific fuel cell cogeneration device 11 is created, and the created advice information is transmitted to the user. Then, by changing the lifestyle according to the advice information sent by the user, it is possible to create a greater amount of carbon dioxide emission reduction. For example, as described above, the user who was notified of the message "Please refrain from using electricity from 8:00 to 9:00 and use it from 4:00 to 6:00." And if you were using an air conditioner, use the washing machine between 4:00 and 6:00 using the reservation function, and refrain from using the air conditioner between 8:00 and 9:00, so that you can use it from 8:00 to 9:00 It is possible to reduce the power and increase the power generated by the fuel cell cogeneration system 11 between 4:00 and 6:00.
