The smart meter 104 constantly integrates the electric power to obtain the electric energy, and outputs the electric energy data shown in FIG. 4B by route A in 30-minute units. The meter data management system 23 receives this electric energy data and transfers it to the payment server 22, and the payment server 22 stores this as electric energy history data as shown in FIG. 9, but stores it in the blockchain format. May be good.

(Order processing)
After completing the user registration, a person who wishes to buy or sell electric power operates the terminal device 105 to generate the order data illustrated in FIGS. 5A and 5B and transmits the order data to the electric power trading server 20.

Here, the attribute at the time of selling order sets the attribute of the power generation facility 101 owned by itself.
On the other hand, the attribute at the time of a buy order specifies the type of electric power that one wants to purchase. For example, if you want to purchase only renewable energy, you may specify solar power, wind power, and hydropower by item, or you may specify renewable energy comprehensively.
The message digest here is, for example, a hash value created by a hash function assigned to the terminal device 105 used by the user.

The electric power trading server 20 receives the order data transmitted from each terminal device 105, classifies the order data into a sell order and a buy order, and stores the order data in the auxiliary storage device 204 and the DB 21.

The method itself for generating order data is arbitrary. For example, the electric power trading server 20 provides a Web page for inputting or selecting data necessary for generating the provided order data, and the user inputs necessary items in the Web page, confirms and approves the data, and automatically. Order data may be generated.

The CPU 201 of the power trading server 20 constantly executes the matching process shown in the flowchart of FIG. 10 by executing the matching program.

In this matching process, the CPU 201 selects a sell order and a buy order that match the conditions using the location, the attribute, the period / time zone, the unit price, and the electric energy as keys (step S11). The matching partner does not have to have one order.

For example, as shown in FIG. 5A, if you want to sell 30kWH from 9:00 on November 10, 2019 to 16:00 on November 17, 2019, for example, from 10:00 to 11 on November 10th. You may conclude a transaction with Mr. A who wants to purchase 15kWH at 10:00 on March 13th and Mr. B who wants to purchase 20kWH from 10:00 on November 12th to 15:00 on November 16th. In this case, the CPU 201 may sell 15 kWH to Mr. A and Mr. B, respectively, according to a preset priority. In this case, Mr. B will run out of purchased power for 5kWH, but this amount will be allocated to all or part of the sales of other applicants for sale, or the electric power company will be based on the contract with Mr. B. The shortage may be supplied.

Similarly, as shown in FIG. 5A, if you want to sell 30kWH from 9:00 on November 10th to 16:00 on November 17th, for example, from 10:00 to November 13th on November 10th. You may conclude a transaction with Mr. A who wants to purchase 10kWH at 10:00 on the day and Mr. B who wants to purchase 15kWH from 10:00 on November 12th to 15:00 on November 16th. In this case, according to the priority, for example, 10 kWH and 15 kWH, for a total of 25 kWH, may be sold to Mr. A and Mr. B, respectively, and the surplus 5 kWH may be sold to another person or purchased by an electric power company. Good.

The CPU 201 calculates the consignment amount of the selected transaction data from the geographical conditions, and determines whether or not the desired trading amount is satisfied even if the consignment amount and the like are taken into consideration (step S12).

Regarding the shipping fee and the like, for example, when the order data of the selling order is received, the shipping fee set in advance may be added to the selling unit price. The method of calculating the transportation fee is optional. An average fixed amount may be added, or a pay-as-you-go amount may be added. As an example of the pay-as-you-go system, for example, after the transaction is completed, the straight line distance or the distance of the transmission line / distribution line may be obtained from the latitude / longitude information of the seller and the buyer, and the consignment charge may be set according to the distance. .. Further, instead of adding it to the unit price, it may be deducted as a fee at the time of settlement processing.

In step S12, if the condition is not satisfied (step S12: No), the condition is returned to step S11, and if the condition is satisfied (step S12: Yes), the transaction is completed and the order combination is registered in the auxiliary storage device 204 and the DB 21 (step S12: Yes). Step S13). In addition, the transaction data shown in FIG. 8 is generated, stored by itself, and transmitted to the payment server 22.
Further, the user table is referred to, and the user is notified by e-mail or the like that the transaction has been completed (step S14).

In this way, the electric power transaction server 20 repeatedly executes processes such as accepting order data, matching orders, notifying the settlement server 22 of the closed transaction, and notifying the user of the matching result.

In the present embodiment, the orderer can set "special conditions" for his / her own order. When the power trading server 20 performs matching in step S11, if the "discerning condition" is set, the "discerning condition" is preferentially considered. For example, a buyer may wish to purchase electricity generated by renewable energy at any price. In this case, the user sets "renewable energy" in the attribute column of the buy order data shown in FIG. 5 (b). Similarly, for example, a buyer may wish to purchase only the electricity generated in a particular area. In this case, the user specifies "J city in K prefecture", "K region", etc. in the power generation area column (not shown) of the purchase order data shown in FIG. 5 (b). Similarly, a seller may want to sell electricity only to users in a particular area. In this case, "L prefecture", "M region", etc. are specified in the consumption area column (not shown) of the sell order data shown in FIG. 5 (a).

The CPU 201 executes the candidate selection process according to the sticking condition shown in FIG. 11 in the matching process step S11 shown in FIG.
In this process, the power trading server 20 determines whether or not there is a particular condition (step S111). If there is Good for, it excludes those that do not meet the conditions of this from the matching of the subject (step S112). The remaining order data is a candidate for matching, and if other conditions are met, a contract is concluded.

For example, when the attribute field of the buy order data that is the target of the matching process is set to "renewable energy", the electric power transaction server 20 steps in executing the matching process of step S11 of FIG. The processing of S111 is executed, it is determined that there is a particular condition, only the sales order data for which the "attribute" is set as sunlight, air volume, geothermal power, hydraulic power, etc. is targeted for matching, and the "attribute" is thermal power, nuclear power, etc. Exclude the set sell order data from the matching target. Similarly, when the "power generation area" column of the buy order data that is the target of the matching process is set to "K prefecture", the power trading server 20 is located in K prefecture with reference to the user data. The sell order data of the user to be matched is targeted for matching, and the sell order data from users located in other regions is excluded from the matching target.

Further, when "K prefecture" is set in the "consumption area" column of the sell order data that is the target of the matching process, the electric power trading server 20 is located in the K prefecture with reference to the user data. The user's buy order data is targeted for matching, and the buy order data from users located in other regions is excluded from the matching target.
It should be noted that a contract cannot be concluded just by satisfying the particular conditions, but a contract can be concluded by satisfying other transaction conditions.

Further, in step S11 of FIG. 10, when performing price matching, it is desirable to perform matching in consideration of the consignment charge (cost for transmitting and distributing electric power from the power generation area to the consumption area). The shipping fee can be fixed, but it is also possible to increase the shipping fee as the transmission and distribution distance increases and decrease the shipping fee as the transmission and distribution distance decreases. The content of the matching process in this case will be described with reference to FIG.

The CPU 201 of the power trading server 20 executes the candidate selection process based on the price shown in FIG. 12 within the process of step S11 of the matching process shown in FIG.

In this process, the CPU 201 first determines whether or not a desired price is set for at least one of the sell order and the buy order selected as matching targets (step S121). When the desired price is set (step S121: Yes), the electric power trading server 20 searches the user data using the user ID included in the order data as a key, and searches for the area such as the user's address, latitude, and longitude. Acquire the information to be specified (step S122). Next, the distance or transmission and distribution route is obtained from the seller's area and the buyer's area, and the unit price of the shipping fee is calculated based on the obtained distance or power transmission and distribution route (step S122). Geographical information may be obtained from the location information of the transaction data. Next, the electric power trading server 20 corrects the desired selling price by adding the unit price of the requested shipping fee to the desired price included in the selling order data, and sets the corrected desired selling price and the buying order data. It is compared with the desired purchase price (step S123) to determine whether or not the condition is satisfied (step S124). If the conditions are met, it is left as a trading candidate (step S125), and if the conditions are not met, it is excluded from the trading candidates (step S126).

For example, it is assumed that the sell order data having a desired unit price of 17 yen and the buy order data having a desired unit price of 18 yen are selected as matching targets. It is possible to make a contract with only the desired price. However, if the unit price of the transportation fee calculated from the locations of the seller and the buyer is higher than 1 yen, the price conditions will not be met and it will be difficult to conclude a contract. By performing such processing, the electric power trading server 20 can set a consignment fee based on rational grounds and promote local production for local consumption of electric power.

In addition to the automatic matching process, the electric power trading server 20 can also enable the user to make a transaction by designating a business partner. In this case, the orderer transmits his / her sell order data or buy order data to the electric power trading server 20. Based on the received order data, the electric power transaction server 20 extracts a certain quantity of order data that can be a candidate for transaction, creates a list as illustrated in FIG. 13, and presents it to the user. Note that FIG. 13 shows an example of a list of candidate sell orders to be traded, which is presented to the user who issued the buy order. The user receives this list in the terminal device 105, selects from this list those that match his / her desired conditions as the target of the transaction, and transmits the transaction request data to the electric power transaction server 20. The electric power transaction server performs matching processing again on the received transaction request data whether or not the contract can be concluded.
At this time, the electric power trading server 20 performs the same processing as in steps S122 and S123 to obtain the consignment charge, and includes the consignment charge, the desired price, and the total unit price thereof in the list. As a result, the user can select an order that can be closed while paying attention not only to the desired price but also to the actual cost.

On the other hand, the settlement server 22 executes the settlement process for each transaction shown in FIG. In this settlement process, the transaction data received from the electric power transaction server 20 is extracted for each account and smart ID unit (step S21), and the electric power is generated based on the transaction data and the electric energy data obtained by the smart meter 104. The sale amount or purchase amount is calculated (step S22).

At this time, for sell orders, the usage fee of this system is charged, and for buy orders, the shipping fee is charged and the usage fee of this system is charged. In addition, it is determined whether or not there was compensation for breach of contract or a penalty, and this is reflected in the settlement. More specifically, the power generation facility 101 owned by the user may not always be able to generate the amount of power specified in the sell order. For example, when the power generation facility 101 is a solar cell, wind power generation, etc., the amount of power generation changes depending on the weather, and the amount of power generation may exceed the amount of power specified in the sell order data, or the specified amount of power may be generated. Sometimes you can't. Therefore, it is necessary to determine whether or not the order data matches the actual amount of power sold or purchased, and if they differ, it is necessary to coordinate with the electric power company .

For example, it is assumed that the sell order shown in FIG. 5A has been completed. In this sell order, 30 kWH of electricity is sold during the trading period. On the other hand, in the power amount data measured by the smart meter 104, it is assumed that the difference between the upstream power amount and the downlink power amount during this transaction period is 31 kWH. In this case, 1kWH of extra electric power is sold. Therefore, the selling amount is the sum of the sales of 30kWh at the desired unit price of 18 yen / kWh and the selling amount of 1kWH to the electric power company. .. Settlement server 22, based on the user data, to identify the electric utilities of the user of the contractor, to determine the power purchase unit price of its electric utility, to identify the payments to the user from the purchase unit price and the amount of power, In addition, the amount billed to the electric power company is set.

Further, it is assumed that the difference between the upstream electric energy and the downlink electric energy measured by the smart meter 104 during this trading period is 25 kWH. In this case, the sales amount is 5kWH short. Therefore, the actual sales are the sum of the sales of 25kWH at 18 yen / kWh and the purchase of 5kWH from the electric power company . Settlement server 22, on the basis of the user data, and identifies the electric utilities of the user contract destination, to determine the power sale price of the electric utility, to identify the billing amount for the user from out bids and electric energy Also, set the amount to be paid to the electric power company .

Further, it is assumed that the buy order shown in FIG. 5B has been completed. In this buy order, 7kWH of electricity is purchased during the trading period. On the other hand, in the electric energy data measured by the smart meter 104, it is assumed that the difference between the upstream electric energy amount and the downlink electric energy amount during this transaction period is 10 kWH. In this case, 3kWH extra power is purchased. For this reason, the price for 7kWh at the desired unit price of 17 yen / kWh, the separately required price for the transportation amount, the system usage fee, and the electricity charge for 3kWH to the contracted electric power company are charged. The payment server 22 sets the payment amount to the electric power company and the payment amount to the power transmission and distribution business operator .
In this way, the settlement server 22 refers not only to the closed sell / buy orders but also to the user table for each contracted transaction, and the power selling unit price and the power buying unit price that the user has contracted with the electric power company. And perform the calculation for settlement. In addition, it also performs billing processing for shipping charges and system usage fees, and calculates the amount of payment to electric power companies and power transmission and distribution companies .

The payment server 22 stores the payment amount for each electric power transaction obtained in this way for each user, each electric power retail trader, and each power transmission and distribution business operator .

In addition, the payment server 22 executes the payment process shown in FIG. 15 at the timing of payment determined for each user.
First, the payment server 22 identifies one user (step S31), and creates a list of individual payment amounts (sale amount, purchase amount) and transaction items during the payment target period (step S32). Then, the total amount of sale and the total amount of purchase are calculated by accumulating the amount of sale and the amount of purchase within the settlement period, respectively. Further, the difference between the total amount of the sale amount and the total amount of the purchase amount is obtained (step S33). At this stage, the amount of electricity sold / purchased with the electric power company is also accumulated.

Next, the payment server 22 performs payment processing according to the payment method defined in the user table shown in FIG. 7 (step S34). For example, if the payment method specified in the user table is a bank account payment process, for example, the bank account specified by the user data is accessed via the Zengin system, and the payment target amount is transferred or withdrawn. In addition, payment by electronic money, payment by exchange, payment by credit card, issuance processing of invoices, etc. are performed.
The payment server 22 transmits payment information to the user via the Internet IN according to the contract details (step S35).

By repeating such processing, the settlement processing of the electric power transaction is executed based on the electric energy measured by the verified smart meter 104. In addition, the settlement server 22, electric utilities, also performs an accumulation process for power transmission and distribution businesses, and the like.

In this way, each user can buy and sell electric power under desired conditions by operating the terminal device 105 and transmitting the order data to the electric power trading server 20.

(Embodiment 2)
In the first embodiment, the A route of the smart meter 104 is used for transmitting the power data, but the C route can also be used. Hereinafter, an embodiment using the C route will be described with reference to FIG.

FIG. 16 is a system configuration diagram corresponding to FIG.
The basic configuration of this support system is basically the same as that of the electric power transaction support system 1 of the first embodiment. However, the meter data management system 23 is installed in the power transmission and distribution business operator , and the electric power trading server 20, the payment server 22, and the meter data management system 23'are installed in the electric power business operator.

The electric power transaction server 20 and the payment server 22 each store the same data as in the first embodiment.
The sell order data and the buy order data are transmitted to the electric power trading server 20. The electric power transaction server 20 executes the matching process shown in FIG. 10 and transmits the transaction data shown in FIG. 8 to the settlement server 22.
The payment server 22 executes steps S31 to S33 of the settlement processing shown in FIG. 14 and the payment processing shown in FIG.
The electric power amount data is transmitted to the meter data management system 23 via the A route, further transferred to the meter data management system 23'via the C route, and transferred to the electric power transaction server 20 and the settlement server 22.

(Embodiment 3)
In the second embodiment, the electric utility itself does not need to execute a trade of power. It is also possible to carry out the electricity transaction processing by a third party with a contract. It is also possible to outsource only part of the electricity transaction processing to a third party. FIG. 17 illustrates a system configuration when the matching process is outsourced to a third party.

In this configuration, the power trading server 20 is installed at a third-party organization that is outsourced.
On the other hand, the payment server 22 and the meter data management system 23'are installed in the electric power company, and the meter data management system 23 is installed in the power transmission and distribution business operator .
In the system configuration of FIG. 17, the processing up to matching of the sell order data and the buy order data is the same as that of the first and second embodiments.
The data of the contracted transaction, that is, the transaction data is transmitted from the electric power transaction server 20 to the settlement server 22 via a dedicated line.
The settlement server 22 executes the settlement process and the settlement process.

The electric energy data from the smart meter 104 is transmitted to the meter data management system 23 installed in the power transmission and distribution business operator . The meter data management system 23 transmits electric energy data for each electric power company to the payment server 22 via the meter data management system 23'via the C route.

(Embodiment 4)
It is also possible to notify the electric power company of the electric power data via the B route. FIG. 18 shows a configuration example when the B route is used.
In this case, the output of the smart meter 104 is transmitted by wireless or power line communication, and is notified to the terminal device 105 via the router 106 via the interface 108 having a function of receiving them. The interface 108 may notify the terminal device 105 directly.
The terminal device 105 appropriately transmits the power data notified by the B route to the meter data management system 23 via the Internet IN. Subsequent processing is the same as in the first embodiment.

Even in this form, it is possible to install the electric power trading server 20 in a third-party organization and the payment server 22 in the electric power company .

An example of configuring a blockchain as the electric power trading server 20 has been shown, but the configuration itself of the electric power trading server is arbitrary.

Further, in the above description, the electric power transaction server 20 and the payment server 22 are distinguished, and the electric power transaction server 20 and the payment server 22 cooperate with each other to support the electric power transaction. An example of doing so was explained. The present invention is not limited to this. For example, the electric power transaction server 20 and the payment server 22 may be composed of one electric power transaction support device having the functions of both servers. In this case, the electric power transaction support device has a receiving means for accepting a sell order and a buy order via a network, a matching means for matching the sell order and the buy order and closing the order, and an electric energy amount for the closed order. It is provided with a payment means for performing payment processing based on the electric energy data obtained by measuring with a meter. It may be functionally configured as part of a large system consisting of multiple computers, such as a cloud server or cloud system.

If the computers provided with the reception means, the matching means, and the payment means are different, the corresponding programs are installed in each.

Further, the server may be installed anywhere, and the management authority may correspond to the above example. Furthermore, management is not limited to the above-mentioned electric power companies, power transmission and distribution companies , third-party organizations with which consignment contracts have been concluded, and the like.

The configuration illustrated in the above embodiment can be changed as appropriate. For example, the configuration of the electric power trading support system shown in FIGS. 1, 3, 16 to 18 is an example, and may be changed as appropriate. Further, the configuration of the user system 10 shown in FIG. 2 can be changed as appropriate. For example, the user system 10 dedicated to power purchase without the power generation facility 101 may be used, or the user system 10 dedicated to selling power not provided with the load 103 may be used.
Further, the communication line connecting the user and the power trading server 20 is not limited to the Internet IN, and any other communication network can be used.

(Embodiment 5)
It is also possible to utilize the above-mentioned electric power transaction support system 1 for demand response. Hereinafter, an embodiment in which the electric power transaction support system 1 is used for demand response will be described.

Here, the demand response is to change the power consumption pattern so that the consumer side suppresses the use of power according to the setting or payment of the incentive when the market price rises or the grid reliability declines. is there.
In the present embodiment, at the time of registering the user information, whether or not to support the demandless response, the contract contents with the electric power company, and the like are registered in advance.

When a request for restraining (restricting) the use of electric power is generated by an electric power company or the like, the request is notified to the electric power trading server 20.
In response to the request, the electric power trading server 20 starts the demand response process shown in FIG.

The CPU 201 of the power transaction server 20 refers to the user table and picks up the user corresponding to the demand response (step S41).

Next, the CPU 201 extracts a target user according to the demand response request content (step S42). For example, when only a specific area is targeted, the target user is extracted from information such as address, latitude, and longitude. Further, for example, when only the user who has a contract with a specific electric power company is targeted, the user who has a contract with the electric power company is extracted from the contract information included in the user information. Further, for example, when only users whose contract capacity is equal to or larger than the reference value are targeted, users with a capacity that satisfies the request are extracted.

For each extracted user, the CPU 201 sets the content (restriction condition) for limiting / suppressing the power consumption based on the content of the demand and the power saving ability of each user according to a predetermined standard (step S43). .. For example, based on the contracted capacity, the upper limit of the power consumption in the requested time zone is set to 2 kWH for the user A, and the upper limit of the power consumption in the requested time zone is set to 8 kWH for the user B.

The CPU 201 inquires about whether or not the registered contacts (for example, e-mail address, push notification of the smartphone application) correspond to the demand response and the restriction conditions for some of the users extracted in step S42. A guide including (for example, period, upper limit of usage amount, etc.) is sent via the communication device 207 (step S43).

After that, the CPU 201 waits for a reply from the user who sent the guidance (step S44). In the case of a reply that the reply accepts the demand response, the CPU 201 accumulates the amount of reduction in power consumption achieved by the acceptance (step S44). The CPU 201 determines whether or not the predetermined timing has been reached (step S45), and if not (step S45: No), returns to step S44. On the other hand, if the predetermined timing is reached (step S45: Yes), it is determined whether or not the cumulative value of the reduction amount has reached the preset target amount (step S46).

If it is determined that the result has not been reached (step S46: No), the process returns to step S43, and the guidance is transmitted to a part of the users who have not issued the guidance.

The CPU 201 repeats the processes of steps S43 to S46 until the cumulative amount of reduction reaches the target amount.
When it is determined that the cumulative amount of the reduction amount has reached the target amount (step S46: Yes), the participant information is saved and notified to the payment server 22 (step S47), and the process ends.

After the end of the demand response period, the CPU of the payment server 22 executes the demand response settlement process shown in FIG. 20, and performs the settlement process for each participant.

The CPU of the payment server 22 sends out one unpaid participant based on the information acquired in step S47 (step S51). Next, from the electric energy history data of the participant, the actual power consumption of the demand response execution time zone is acquired (step S52), and it is determined whether or not the demand response limit assigned to the user is satisfied. (Step S53).

If it is determined that the restriction is satisfied (step S53: Yes), a preset reward is given to the participant (step S54), and if it is not satisfied (step S53: No), step S54 is skipped. ..

The CPU of the payment server 22 determines whether or not the settlement based on the demand response has been executed for all the participants (step S55), and returns to step S51 if the unsettled participants remain (step S55). : No) If the settlement has been completed for all the participants (step S55: Yes), the process ends.

The CPU of the payment server 22 considers the reward given in step S54 in steps S32 and S33 of the payment process of FIG. For example, when a certain reward amount is given as a reward, the fact that the reward is a demand response is recorded as an item in the list in step S32, and the reward amount is included in the payment amount to the user. ..
As a result, demand response can be performed more efficiently.

It should be noted that the pre-registration of the demand response may be omitted, step S41 may be skipped, and the process may be started from step S42. In addition, the method of power usage restriction and the reward for satisfying the restriction conditions can be set arbitrarily.

(Embodiment 6)
In the above-mentioned electric power transaction support system 1, the target of processing was only matters related to electric power. The present invention is not limited to this. The target of processing is arbitrary.
An example of processing gas charges and water charges as well as electricity charges will be described.

In the present embodiment, as shown in FIG. 21, the smart meter 104, the gas meter 1010, and the water meter 1020 are the control unit 1042, 1012, 1022 and the communication device 1043, 1013 together with the instrument main body 1041, 1011, 1021, respectively. 1023 is provided. Further, the smart meter 104, the gas meter 1010, and the water meter 1020 include input devices 1044, 1024, 1024, and display devices 1045, 1015, 1025, respectively.

The instrument main body 1041, 1011, 1021 measures the power consumption, the gas consumption, and the water consumption, respectively.

The control units 1042, 1012, 1022 include a processor and a timer, and control each unit. The communication devices 1043, 1013, and 1023 are connected to each other via the home network HN and communicate with other devices. The input devices 1044, 1024, 1024 input arbitrary information such as setting information, and the display devices 1045, 1015, 1025 display measurement data, menus, and the like.

In the present embodiment, it is assumed that each user has previously agreed to bill and pay the gas usage fee and the water usage fee via the electric power transaction support system 1. In this case, the contracted gas company, the rate plan, the contracted water company, the rate plan, and the like are registered in advance in the user table.

The control unit 1012 of the gas meter 1010 and the control unit 1022 of the water meter 1020 each execute the meter data transmission process of FIG. 22 at an appropriate cycle by a timer interrupt or the like, and first, whether or not the data transmission timing has been reached. Is determined (step S61).
If the transmission timing has not been reached (step S61: No), the process is completed, and if it has been reached (step S61: Yes), the measurement data from the previous transmission to the latest is transmitted to the communication devices 1013 and 1023, the home network. It is transmitted to the smart meter 104 via the HN (step S62).

The control unit 1042 of the smart meter 104 receives the transmitted measurement data via the communication device 1043 and temporarily stores it.

The control unit 1042 of the smart meter 104 executes the meter data transmission process of FIG. 23 at an appropriate cycle by a timer interrupt or the like, and first determines whether or not the data transmission timing has been reached (step S71).
If the transmission timing has not been reached (step S71: No), the process is completed, and if it has been reached (step S71: Yes), the measurement data of the gas meter 1010 and the water meter 1020 that have been received and stored are stored in A. It is transmitted to the payment server 22 via the route, the B route, or the C route and the meter data management system 23.

In the payment server 22, the control unit 1042 of the smart meter 104 receives the transmitted measurement data via the communication device 1043 and temporarily stores it. The CPU 201 of the payment server 22 obtains the gas usage fee from the data received from the gas meter 1010 from the contract information and the like registered in the user data. The CPU 201 of the payment server 22 obtains the water charge and the sewerage charge from the contract information and the like registered in the user data from the data received from the water meter 1020.

The CPU 201 of the payment server 22 uses the gas usage fee and the water usage fee obtained in steps S32 and S33 of the payment process of FIG. 15 as a part of the billing amount to the user.
On the other hand, for each gas company and water company, after deducting commissions, they are accumulated and processed as sales amount for each company.

In this way, the electricity charge, the gas charge, and the water charge are collectively processed for each user.

In the above description, the configuration in which the gas meter 1010 and the water meter 1029 are provided with the communication devices 1013 and 1023, respectively, has been illustrated, but the configuration is arbitrary as long as the measured value can be transmitted to the smart meter 104. For example, an external device that optically reads the measured values displayed by the display devices 1015 and 1025 of the gas meter 1010 and the water meter 1029 and transmits them wirelessly or by wire to the communication device 1043 of the smart meter 104 is arranged. May be good.

In the above description, an example of processing measurement data of a gas meter and a water meter in addition to a smart meter has been shown, but the data to be processed is not limited to gas usage data and water usage data. Data that is subject to billing or billing acquired by any other device can be processed.
