DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of measuring the amount of household energy per hour.

[0002]

2. Description of the Related Art Conventionally, in a household energy metering method (in the case of electric power), metering is performed using a type of integrating wattmeter (hereinafter, referred to as a normal type integrating wattmeter) that cannot measure the power consumption for each time zone. Had gone. In the case of measuring the nighttime power, it is necessary to install another nighttime power integrating meter in addition to the normal-type integrated power meter to measure the nighttime power. In such a household power metering method, two integrating wattmeters must be installed. For example, even if two integrating wattmeters are installed, the integrating wattmeter of the normal type integrating wattmeter can be used at any time. It is not possible to identify which is the case, and the power user should be able to use it at night rather than at the peak of the day, but if the power rate is the same regardless of the time of use However, there was a problem that there was no awareness of avoiding peak hours during the day. On the other hand, the household energy metering method (in the case of city gas) did not use hourly gas meters. Also, in the case of city gas, unlike the case of electric power, there was no night rate system itself. For this reason, the city gas consumers are made aware of peak power savings, such as using gas appliances for power peak cutting without using air conditioning with commercial power, especially during the peak power hours in the summertime. It was a difficult situation. As described above, in the household energy metering method, conventionally, there has not been considered a method of calculating a household energy fee during a fee calculation period. This means that weighing systems need to be installed in hundreds of thousands or millions of households,
Furthermore, it is difficult to efficiently acquire and collect a huge amount of household energy information for each time zone in the external processing system. Conventionally, information and information on household energy consumption
Acquisition work could not be leveled, and the efficient operation of household energy production and supply systems in the entire energy supply area or country could not be achieved.

(Explanation of terms) Hereinafter, explanations of terms used as constituent elements of the present invention (including the embodiments of the present invention) are as follows.・ Household energy means the amount of energy used in each household. Representative household energy includes household power and household city gas. In this specification, the amount of household energy is simply referred to as the amount of energy,
It may be abbreviated as the amount of energy used or the amount of energy used. The charge calculation period generally refers to a period determined for charge calculation, and is set in advance based on a charge system that determines a charge per unit energy amount.
During this period (T1 to T2), the same rule is applied for charge calculation. The same rule means that the rules applied during the charge calculation period are the same, such that the charge per unit energy does not differ depending on the day within the charge calculation period. The charge calculation period (T1 to T2) specifically refers to, for example, from midnight of the first day ds to 24:00 of the last day de. In this case, in effect, the first day d
This is synonymous with a period from s to the last day de. In the normal case, midnight on the first day of the month is the starting time, and 24:00 on the last day of the month is the expiration. Within the same fee calculation period, the fee calculation period shall be determined so that the same fee calculation method is used. The fee calculation period is mainly determined based on the fact that monthly fees are customarily common or to introduce seasonal fees. The time zone is generally Δt1, Δt2... Δt
It is represented by n. Δt1 = t0−t1, Δt2 = t1−t2... Δt
n = tn-1 to tn Here, t0, t1, t2... tn represents time, t0 represents midnight, and tn represents 24:00.・ The time-based charges are time periods Δt1, Δt2... Δ
In principle, tn refers to a fee that is determined based on a fee system that varies depending on the time of day. Alternatively, the measurement may be performed, for example, every hour (or every 0.5 hours) regardless of the fee system. The household energy fee during the fee calculation period is specifically calculated as follows. That is, after transmitting the home energy amount for each time zone stored in the storage device to the external communication device, the external processing system calculates the home energy amount for each time zone and the charge per unit energy amount for each time zone. The calculation is performed by calculating the household energy rate within the rate calculation period by multiplying and adding up. More specifically, the household energy rate E within the rate calculation period
(T2) is determined by the following equation. E (T2) = C0 + C1 * E1 (T2) + C2 * E2 (T2) +... + C n * En (T2) Equation 1 where C0 is the basic charge, C1, C2,. ,
Expresses the charge per unit energy (pay-as-you-go). C1, C2... Cn, in principle, have different numerical values. The storage device is a memory CM, time zones Δt1, Δt2,.
..., Memories R1 and R2 corresponding to Δtn
n and / or memory M1, M2... Mn. The values stored in the memory CM and CM, memory R1, R2 are stored in ............ Rn numeric were as R1, R2 ............ Rn, memory M1, M2
..., M1 , M2, ...
Mn . Here, the memory CM also has a purpose of counter operation and is also called a register. The output of the energy metering unit (which outputs a frequency proportional to the amount of energy used) is frequency-counted, and is stored as a numerical value CM in the memory CM every moment. The memories R1, R2,..., Rn and / or the memories M1, M2,. Memory CM and / or memory R1, R2 ...
... Rn and / or memories M1, M2... Mn are desirably nonvolatile memories. because,
Non-volatile memory CM, non-volatile memory R1, R2 ...
... Energy amount information ( CM ,
R1 , R2 ... Rn is included. ) Continue to be stored and accumulated even during a power failure. Since the commercial power is not used from the power failure to the power re-supply, the energy amount is not counted, and the energy amount count is restarted after the power re-supply. There is no problem in weighing. However, in the case of city gas, since the city gas continues to be used from the time of the power outage until the power is resupplied, the energy amount should be counted, but unfortunately it is not possible.
Therefore, the usage of city gas cannot be measured from the power failure to the re-supply of power, which is a problem, and it is necessary to take measures with a backup system such as a battery. As described above, the role played by the memory unit provided in the distributed installation system is particularly important in the present invention. The memory part provided in the distributed installation system is
At least a certain period (for example, a period after a predetermined period elapses after the expiration of the charge calculation period, or a period until the call signal is received and the household energy amount for each time zone stored in the storage device is transmitted to the external communication device) ), A device that stores and stores energy usage information. Even if the expiration of the charge calculation period has elapsed (for example, 24:00 on the last day of the month), by storing and accumulating the energy usage information in the memory unit provided in the distributed installation system, it is immediately possible Since there is no need to transmit the energy usage information to the external communication device, the role played by the memory unit is particularly important for leveling the operation of obtaining the energy usage information. When the communication device provided in the distributed installation system receives the call signal from the external communication device, or after a predetermined period has elapsed after the expiration of the fee calculation period, the communication device provided in the distributed installation system uses the communication device to transmit the energy usage information. Send to external communication device.
Here, the predetermined period may be set appropriately in advance so that the energy usage information work is leveled from the viewpoint of the entire system. Regardless of whether it is due to a call signal or after a predetermined period, the call signal transmission timing and a predetermined period elapse according to a schedule plan so that the energy usage information can be leveled into the central system and efficiently taken in. The time is set. As described above, by transmitting the energy usage information stored in the memory unit to the external communication device, it is possible to efficiently obtain the energy usage information during the charge calculation period of the distributed installation system distributed and installed in various places. it can. It is possible to avoid collectively acquiring energy usage information after the elapse of the charge calculation period, the work of acquiring energy usage information is leveled, and the energy usage information acquisition efficiency of the method of the present invention is greatly improved. . Again,
The present invention is characterized in that a distributed installation system itself is locally distributed and installed, and it is particularly important to adopt a configuration in which energy usage information is efficiently acquired in an external communication device. When the storage device is composed of non-volatile memory, in the case of power failure, etc. (When a backup system such as a storage battery is not installed, or it is out of order even if it is installed)
Therefore, the energy consumption (limited to electric power) immediately before the power failure can be stored in the memory unit CM and / or M1 to Mn and / or R1 to Rn even during the power failure, so that the power supply is restarted. If the measurement is restarted from time, there is no problem in collecting energy consumption information. During a power outage, the power consumption is zero, so the storage device (memory unit C
The energy usage information (energy usage information used before the power failure) stored in M and / or M1 to Mn and / or R1 to Rn) is continuously stored during the power failure and is effective even after the restart. This is because it can be used. However, if the clock of the distributed installation system stops due to a power failure, the time of the clock of the external processing system is transmitted to the communication device via the external communication device, so that the clock is adjusted.
The energy usage metering will be resumed. Even if the energy consumption is city gas, even in the event of a power outage (in the case where a backup system such as a storage battery is not installed, or it is installed but it is out of order), city gas is consumed, , The amount of city gas used cannot be measured, but the amount of city gas (non-volatile memory (CM and / or M1 to Mn and / or R
1 to Rn). ) Is weighed. Even if the energy consumption taken into the external processing system is lost due to failure or volatilization, etc., if it is stored in the nonvolatile memory in the distributed installation system, the call signal from the external communication system can be transmitted. Since the energy consumption ( CM and / or M1 to Mn and / or R1 to Rn ) stored in the non-volatile memory can be obtained by transmitting to the communication device, there is an advantage that there is no problem in charge billing. Yes. Conventionally, hundreds of thousands,
Millions of millions of customers' energy usage information (sometimes needed to store information for the past years)
It was necessary to separately save the past information by a backup system, which required a special storage space and labor costs for information maintenance. When stored and stored in a storage device installed in each distributed installation system as in the present system, there is also a special advantage that it is not necessary to concentrate and save a huge amount of energy use information of customers.

FIG. 1 is a block diagram of the system of the present invention. FIG. 1 shows an embodiment of the present invention, which will be described with reference to FIG. The distributed installation system 100 includes an energy amount measuring unit 2, a clock 5, a control device 10, a storage device 15, and a communication device 18. External processing system 500
Comprises a clock 55, an external communication device 58, and the like. Further, there is a data system (not shown) for storing home energy information (including past home energy information). Further, it generally includes a communication device (not shown) that communicates with the energy amount information transmission system 600. The energy meter 2 transmits a frequency signal proportional to the amount of the household energy 1 supplied. The control device 10 uses the clock 5 to control the time t0 (that is, 0 am
), The frequency signal is reset in the counter memory CM, that is, CM = 0, and a new count is started in the same manner as the normal frequency count. Then, at time t1, the count number CM is added to the numerical value R1 of the memory R1 of the energy amount measuring unit 2, and the added numerical value ( R1 = R1 + CM ) is controlled to be newly stored. At the same time, the counter memory CM is reset, that is, CM = 0, and counting of the frequency signal is newly started. Then, at time t2, control is performed so that the count number CM is added to the numerical value R2 of the memory R2 of the energy amount measuring unit 2, and the added numerical value ( R2 = R2 + CM) is newly stored. Repeat the following, the amount of energy metering unit 2, if the time ti-1, the control unit 10 resets the counter memory CM, i.e. C
M is set to 0, and counting of the frequency signal is started. Only while the household energy is being used, the frequency signal is counted in an amount proportional to the household energy used.

Is transmitted to the external communication device. As a result, in the external processing system, the amount of household energy for each time zone can be efficiently measured. That is, in the external processing system, the household energy amount within the charge calculation period is calculated by multiplying the hourly household energy amount by the hourly amount and the rate per unit energy amount for each time zone and adding the results. More specifically, the household energy rate E (T2) within the rate calculation period is determined by the following equation.

However, if necessary, correction may be performed in a distributed installation system or a centralized system. . Further, a case of a power failure or the like will be described.
If the output of the energy amount measurement unit is always stored in a storage device (memory CM), when a power failure occurs, the household energy amount in a time zone including the time of the power failure is stored in the count memory CM. After the restoration of the power failure, if the time period is the same as the time zone including the time of the power failure (at the time of the restoration of the power failure, according to the clock of the distributed installation system), the count memory CM
The count is restarted while the numerical value CM of the above is kept as it is. If the time period is not the same as the time period including the power outage, the numerical value CM of the count memory CM is stored in the storage device (R1 to Rn) for home energy during the time period including the power outage, and the count memory CM is cleared. Then ( CM =
0), restart counting of household energy. In this way, even if a power failure occurs, if the household energy is commercial power, the commercial power will not be consumed during the power failure, and the household energy during times other than during the power failure will be:

If the amount of household energy is city gas, the city gas is consumed even during a power outage, so that it is necessary to measure the city gas using a backup system such as a battery. However, if the household energy is city gas, all the city gas consumption before the power outage is stored in the storage device, so only the city gas consumption during the power outage is affected by the power outage.
