<Configuration>
FIG. 2 is a block diagram showing the configuration of the electricity bill system of the present embodiment. As shown in this figure, “Electricity Billing System” 0200 of this example includes “Building Electricity Usage Measurement Device” 0201, “Tenant Electricity Usage Measurement Device” 0202, and “Shared Department Electricity Usage Measurement Device”. 0203, “Electricity usage storage device” 0204, “Payment amount calculation device” 0205, and “Tenant device” 0206.

  The “Electricity Charge System” of this embodiment is an electricity charge collection and storage service agency that collects the electricity charges that are incurred by each tenant in a building where one or more tenants are occupying on behalf of the person responsible for collecting the electricity charges for that building. This is a system used by a contractor.

  “Building electricity usage measuring device” is an entire building that serves as a reference for calculating the amount of electricity bill billed by the power company supplying power to the building to the person who is obliged to pay the electricity bill for the building. It has a function to measure and output the amount of electricity used in the power supply line of the entire building.

  As a power supply line for the entire building, a power line for collectively receiving power from a power company in units of buildings can be considered. The power supply line of each tenant and the power supply line of the common part, which will be described later, are branched from the power supply line of the entire building. Conceptually, the power supply line of each tenant and the power supply line of the common part are The bundle is the power supply line for the entire building.

  The amount of electricity bill to be charged by the power company to the person who is obligated to pay the electricity fee is based on the electricity usage of the entire building measured by the building electricity usage measuring device and the electricity bill calculation standard of the power company. Calculated based on The calculation processing is mainly considered to be performed by a device managed by an electric power company, but may be performed by any device (for example, a payment calculation device described later) of the electricity rate system of this embodiment. Is possible.

  As the output means for the amount of electricity used for the entire building, a display output means, a print output means, a data recording output means, and the like are possible.

  The “tenant electricity usage measuring device” has a function of measuring and outputting the electricity usage of each tenant in the power supply line of each tenant that branches from the power supply line of the entire building.

  Here, the power supply line of each tenant branched from the power supply line of the entire building is a power line that supplies power only to each tenant. The output destination corresponds to an electricity usage storage device and each tenant device described later, but a configuration of additionally outputting to other devices is also possible. In addition, a configuration in which display output means, print output means, data recording output means, and the like are provided is also possible.

  The “shared part electricity usage measuring device” has a function of measuring and outputting the electricity usage of the common part in the common part power supply line branched from the power supply line of the entire building. Here, the common part power supply line branched from the power supply line of the entire building is a power line that supplies power only to the common part. As an output destination, each tenant device can be used in addition to the electricity usage storage device described later. Further, a configuration in which display output means, print output means, data recording output means, and the like are additionally provided is also possible.

  As a measuring means of each of the above measuring devices, a method of obtaining the data by providing an ammeter or CT sensor in the power supply line can be considered, but it is not particularly limited thereto. It should be noted that wired or wireless communication means can be used as means for outputting data to other devices. However, in order to reduce the construction burden, it is preferable to use wireless communication means inside the building. In this case, it is conceivable to use an interface for converting to wireless data.

  “Electricity usage storage device” is installed in the building, and accumulates and outputs each tenant's electricity usage amount acquired from the tenant electricity usage amount measuring device and the common portion electricity usage amount measuring device and the electricity usage amount of the common part. It has a function. The configuration further includes a configuration that acquires, accumulates, and outputs the electricity usage of the entire building from the building electricity usage measuring device.

  As a means for accumulating information, it is mainly considered to use a storage device that records in a non-volatile recording medium such as an HDD or a flash memory, but other storage devices can also be used. Here, it is conceivable to hold each electric usage amount in association with the identification ID of each measuring device so that the electric usage amount of each tenant can be distinguished from the common portion. These associations may be performed in each measuring device or may be performed in the electricity usage accumulation device.

  As a means for outputting to a payment amount calculation device or the like to be described later, a wired or wireless communication means can be considered. However, it is conceivable to perform communication mainly using the Internet network, a mobile phone network, or a PHS line network. In addition, it is possible to adopt a configuration in which information on the amount of electricity used can be transmitted at a predetermined date and time. Also, it is possible to detect whether or not the communication line is congested, and select and transmit a non-congested time zone.

  The “Payment amount calculation device” is installed at the center that manages and manages information related to the electricity usage of multiple buildings, and acquires the electricity usage of each tenant and the electricity usage of the common part from the electricity usage storage device of each building. Then, the total amount of electricity that each tenant of the building should pay to the electricity bill collection and storage business agent is the building electricity usage measuring device for the period of calculation and the period of the agent It is calculated based on the amount of electricity used for the entire building measured at the above and the electricity charge calculation standard of the electric power company, so that it does not fall below the amount of electricity bill to be charged from the electric power company to the person who pays the electricity charge In accordance with the rules set forth in 1), each tenant of the building has a function of calculating and outputting an electricity bill to be paid to the electricity bill collection and storage business agent. In this configuration, the electricity usage of the entire building is further acquired from the electricity usage storage device of each building, and the electricity bill that each tenant of the building should pay to the electricity bill collection and storage service agent is calculated. In this case, the output configuration is also included.

  The plurality of buildings include the building electricity usage measuring device, the tenant electricity usage measuring device, the shared partial electricity usage measuring device, the electricity usage storage device, the tenant device described later, and the like. . In the center, each building can be identified using an identification ID or the like, and information relating to the electricity usage of each building can be managed in association with the identification ID or the like.

  As the calculation process based on the above rules, the basic charge for each tenant is calculated by using the basic charge unit price, the electricity charge unit price, etc., which is the electricity charge calculation standard of the electric power company, and it is added to ensure that it does not fall below A process of adding and distributing the amount according to the electricity usage of each tenant can be considered. The following can be considered as specific examples of the rule.

(Specific examples of rules)
(1) Electricity charges for each tenant = dedicated partial charge + shared partial charge (2) dedicated partial charge = basic charge + electricity charge + meter reading charge + in-building electricity supply facility maintenance charge (3) basic charge = basic charge unit price [Yen] x Contract power for each tenant [kW] x Power factor discount / additional premium [%]
(4) Electricity charge = Electricity charge unit price [yen] x Electric power consumption of each tenant [kWh] ± Fuel cost adjustment [yen]
(5) Fuel cost adjustment amount = Electricity consumed by each tenant [kWh] x Fuel cost adjustment unit price [yen]
(6) Meter reading charge = Meter reading charge unit price [yen] x Electric power used by each tenant [kWh]
(7) In-building electricity supply facility maintenance fee = In-building electricity supply facility maintenance fee unit price [yen] x Electric power consumption of each tenant [kWh]
(8) Shared charge = basic charge + power charge (9) Basic charge = basic charge unit price [yen] x contracted electricity for common use [kW] x power factor discount / additional charge [%] x for each tenant Burden ratio [%]
(10) Electricity charge = Electricity charge unit price [yen] x Electricity used in common area [kWh] x Load ratio of each tenant [%]

  The basic charge unit price and the electricity charge unit price are the amounts announced by the power company, and the basic charge unit price of the power company is held as part of the rule information. Further, when the input of revision information is accepted, a process of newly holding as part of rule information is performed. Contract power for each tenant and shared part is calculated based on the information held by the power company as part of the rules. For example, it is conceivable that either the maximum demand power for the current month or the maximum demand power for the previous 11 months is set to a larger value. In addition, the contract power of each tenant for each month in the period of 12 months from “Electricity usage measurement start date” is the maximum demand power for this month and the maximum demand power from “Electricity usage measurement start date” to the previous month. Of these, it is conceivable to set a larger value. Information on the method announced by the electric power company is also stored as part of the rules for power factor discounts, surcharges, and fuel cost adjustments. Information such as the power factor and burden ratio of each building is held in advance as part of the rules.

  In the rules in the above example, the electricity usage amount of each tenant and common part is based on the rules for calculating electricity charges applied by the power company to the electricity usage of the entire building. There is a low risk that the amount charged by the electric power company for the amount of electricity used will be less than the total amount charged for electricity bills charged to each tenant by the electricity bill collection and storage business agent. In addition, it is possible to calculate an appropriate billing amount for each tenant, and there is no need to overload the meter reading fee and the in-building electric supply facility maintenance fee, which are additional amounts.

  In addition, when the electricity usage of the whole building is acquired from the building electricity usage measuring device via the electricity usage storage device, the following rules can be added.

(11) Shared partial charge (new) = Shared partial charge (old) + Transformer loss charge (12) Transformer loss charge = Electricity charge unit price [yen] x {Energy consumption of the entire building [kWh]- Electricity consumption [kWh] for each tenant-Electricity consumption for common areas [kWh]} x burden ratio [%]

  Even if there is a significant difference between the electricity usage value of the entire building, the electricity usage amount of each tenant, and the sum of the electricity usage amount of the common part by further using this rule, the difference Since the rules according to the electricity bill calculation standard of the electric power company are used for the amount of electricity used, it is possible to reduce the risk of lowering and to calculate a more appropriate billing amount for each tenant.

  The “tenant device” is installed in each tenant of the building and the tenant's electricity usage acquired from the tenant electricity usage measuring device and the tenant acquired from the payment calculation device are It has a function of displaying the electricity bill to be paid.

  As an acquisition means from the payment amount calculation apparatus, a configuration provided corresponding to the output means of the payment amount calculation apparatus can be considered. Communication means using the Internet network, mobile phone network, PHS line network, etc. are mainly considered. In addition, a configuration is possible in which the electricity usage amount storage device and other information storage devices are arranged at a relay point between the payment amount calculation device and each tenant device. By adopting such a configuration, information aggregation is enhanced.

  It is conceivable to use a general display output means such as a display as the display means. In addition, a configuration in which audio output means, print output means, and the like are separately provided is also possible. As described above, each tenant device can grasp information on its own electricity usage and information on electricity charges. Information on the electricity usage of each tenant can be displayed with little time lag because it is received directly from the corresponding tenant electricity usage measuring device. In addition, since the information on the electricity bill of each tenant is calculated by the payment amount calculation device, the processing burden on each tenant device can be reduced, and each tenant device can be configured more simply.

In addition, since it becomes easy to use accurate data for each amount of electricity used, it is possible to perform a more appropriate calculation process of electricity charges.

  In addition, the measured value abnormality detection device gives an index of the change in the electricity usage of the entire building, the electricity usage of each tenant and the electricity usage of the common part over the most recent past predetermined time with the output of the abnormality detection signal. It is also possible to employ a configuration that further includes means for respectively calculating and specifying a tenant measuring device or a shared partial measuring device in which the measurement result of the amount of electricity used has changed by a predetermined amount or more at the same timing as the abnormality detection signal.

  As an index of the change in the amount of electricity used, the amount of change in the amount of electricity used per unit time, the rate of change, and the like can be considered, but are not particularly limited thereto. When a plurality of measuring devices are specified as candidates, it is also possible to output as a measuring device that may have an abnormality in the measured value.

  In addition, when the measurement result abnormality detection device is a tenant electricity usage amount measuring device when the measurement result of the electricity usage amount has changed more than a predetermined value at the same timing as the abnormality detection signal, The tenant device of the tenant may further include a means for outputting an abnormality detection signal. In this case, each tenant device has means for displaying information indicating that an abnormality has occurred in the measurement value of the tenant electricity usage measurement device of the tenant based on the abnormality detection signal acquired from the measurement value abnormality detection device. It is conceivable to further provide a configuration.

  With this configuration, each tenant can easily grasp that there are some errors in their electricity usage displayed on the tenant device. Can be prevented.
