Manual meter reading may be performed on a meter for meter reading (not shown).

Referring back to FIG. 1, when the remote meter reading and the manual meter reading are performed according to the meter reading item, the data acquisition unit 215 acquires the remote meter reading data acquired according to the remote meter reading and the manual meter reading data acquired according to the manual meter reading. Specifically, when the remote meter reading is performed by the meter for the remote meter reading according to the meter reading item, the data acquisition unit 215 may acquire the remote meter reading data from the meter for the remote meter reading.

In addition to knowing whether the meter is initialized or generating an error, there is an effect that it is possible to calculate the exact energy consumption. As described above, it is possible to distinguish between the initialization of the meter and the error of the meter, but for convenience of description, it is described that the initialization of the meter is included in the error of the meter.

When the integrated data is generated, the data integration unit 220 stores the integrated data in the database 240 and transfers the integrated data to the energy usage calculation unit 230.

The energy usage calculation unit 230 calculates energy usage for each zone of a building using the integrated data 330 generated by the data integration unit 220. Specifically, the energy usage calculation unit 230 extracts a value recorded in any one of the first data field and the second data field of the integrated data 330 according to a predetermined criterion to determine energy usage for each zone. Calculate. At this time, the standard may be set by the user to either manual reading data or remote reading data for each zone. For example, the user may set the reference as the manual reading data in the first zone in the building, and the reference as the remote reading data in the second zone.

The energy usage calculation unit 230 may correct the calculated energy usage according to a predetermined criterion for each area of the building.

Hereinafter, the energy usage calculation unit will be described in more detail with reference to FIG. 4.

4 is a view showing the configuration of the energy consumption calculation unit according to an embodiment of the present invention.

The energy usage calculator 230 includes a first energy usage calculator 410, a second energy usage calculator 420, a third energy usage calculator 430, a final energy usage calculator 435, and an estimation unit ( 440), and an energy usage correction unit 450.

The first energy usage calculation unit 410 calculates the first energy usage of the common area commonly used by energy consumers occupying each area of the building area according to the ratio of the area of the common area to the total area of the building. Specifically, the first energy consumption calculator 410 calculates the total energy consumption of all energy consumers by using the integrated data of the integrated meters of the area occupied by each energy consumer, and calculates the total energy consumption of all energy consumers from the total energy consumption of all buildings. The first energy consumption of the public area can be calculated according to the ratio of the area of the public area to the total area.

At this time, the energy consumer may include a tenant who is an office space rental customer or a tenant who is a commercial space rental customer.

The second energy consumption calculator 420 calculates the second energy consumption of the area occupied by each energy consumer. Specifically, the second energy usage calculator 420 may calculate the second energy usage of each energy consumer using the integrated data of the area occupied by each energy consumer.

The third energy usage calculator 430 calculates the third energy usage of each energy consumer by distributing the first energy usage of the common area to the second energy usage of each energy consumer. Specifically, the third energy usage calculation unit 430 determines the first energy use in the public area according to the ratio of the area of each energy consumer to the total area of all energy consumers or the ratio of the sales of each energy consumer to the total sales of all energy consumers. It is distributed to calculate the third energy consumption of each energy consumer.

For example, when the energy consumer is a tenant, the third energy usage may be calculated by distributing the first energy usage in the common area according to the area ratio of each tenant. In addition, when the energy consumer is an occupant, the third energy use can be calculated by distributing the first energy use in the common area according to the sales ratio of each occupant.

The final energy usage calculator 435 calculates the final energy usage of each energy consumer by adding the third energy usage calculated for each energy consumer to the second energy usage of each energy consumer.

Accordingly, the final energy usage of the first energy consumer may be calculated by adding the third energy usage by the final energy usage calculation unit 435 to the estimated second energy usage.

The energy usage correction unit 450 corrects at least one of the area of each zone occupied by each energy consumer, the sales amount of the energy consumer, the past energy usage of each zone, and the trend of past energy use in each zone in a predetermined correction formula. The energy consumption can be corrected by inputting it as a coefficient and inputting the energy consumption calculated for each zone as a correction variable of the correction equation. Here, the area may be the ratio of the area of each district to the total area of the building, and the sales may be the ratio of the sales of each energy consumer to the total sales of all energy consumers.

For example, the energy usage correction unit 450 may correct the energy usage of each tenant according to the area ratio of each tenant, if the energy consumer is the tenant, and if the energy consumer is the tenant, each tenant according to the sales ratio of each tenant It can correct the energy consumption.

In addition, the energy usage correction unit 450 corrects the energy usage by using the previous month's energy usage and energy usage trend of the month in which the energy usage was calculated, energy usage and energy usage trend of the same month of the previous year, and energy usage and energy usage trend of the same month of the previous year. Can. If these examples are followed, energy consumption can be corrected by using the average value of the previous month's energy use, the same month's energy use in the previous year, and the average energy use in the same month of the previous year.

In one embodiment, the correction equation may be a polynomial form defined by a user for each section of a building. When following this embodiment, the user can define an appropriate correction equation for each zone of the building, thereby improving the accuracy of energy consumption calculated for each zone.

In one embodiment, if the energy usage correction unit 450 records a flag indicating initialization or error occurrence in the third data field of the integrated data 330, the energy usage of the zone where the initialization or error occurred is determined in each zone. This can be corrected by using the past energy use of and the trend of past energy use in each area.

In one embodiment, when the sum of the total energy supply of the energy usage correction unit 450 and the energy usage calculated for each zone is different, it is determined that the missing energy usage is generated, and the energy usage calculated for each zone is omitted. Energy usage can be compensated.

The energy usage calculation unit 230 stores the calculated energy usage in the database 240 and transfers the calculated energy usage to the billing calculation unit 270.

The learning unit 260 trains the energy usage calculation unit 230 using the integrated data 430 and energy data stored in the database 240. In one embodiment, the learning unit 260 may train the energy usage calculation unit 230 using supervised learning. When following such an embodiment, the learning unit 260 may supervise the correction equation used by the energy usage calculator 230 to perform the correction. For example, the learning unit 260 may supervise the correction coefficient of the correction formula.

The learning unit 260 according to the present invention supervises the energy usage calculation unit 230 using integrated data and energy data in which remote metering data and manual metering data collected and categorized according to meter reading items are integrated ( Supervised Learning), it has the effect of improving the learning speed.

The billing unit 270 calculates the billing amount for each area of the building by multiplying the calculated energy use by the energy price according to the load for each time zone when the energy use for each section of the building is calculated by the energy use calculating unit 230. Can. Here, the load for each time zone may include a light load time zone, a heavy load time zone, a maximum load time zone, and the like.

The energy analysis unit 280 may generate energy data based on the integrated data collected during a predetermined period in the past, and analyze energy use habits of each region based on the generated energy data. At this time, the energy data may include the past energy usage of each zone, and the past energy usage trend of each zone.

For example, the energy analysis unit 280 may analyze energy usage habits of each region, such as time zone and season, by using energy data. At this time, the energy data may include past energy usage and past energy usage trends. The energy analysis unit 280 stores the generated energy data in the database 240.

As described above, the present invention can analyze energy usage habits using integrated data incorporating manual metering data and remote metering data collected by manual metering and remote metering, and also for areas for calculating energy consumption by manual metering. It has the effect that it can produce meaningful data analysis results.

Hereinafter, a building energy management method (hereinafter referred to as a “building energy management method”) using a remote meter reading and a manual metering method according to the present invention will be described with reference to the accompanying drawings.

5 is a flowchart showing a building energy management method according to an embodiment of the present invention. The building energy management method shown in FIG. 5 may be performed by a building energy management system as shown in FIG. 1.

First, the building energy management system generates a plurality of meter reading items for each zone of the building (S500). Specifically, the building energy management system generates a plurality of meter reading items for a plurality of meters installed for each section of the building. The meter reading item may include identification information of each meter and a physical quantity of an energy type measured by each meter. At this time, the plurality of meters may include a plurality of meters for remote meter reading and a plurality of meters for manual meter reading.

In one embodiment, the building energy management system may generate a meter reading item according to a control point stored in the database. Here, the control point can be set by connecting the facility and the characteristics of each facility. For example, a control point may be set according to a facility classification system utilized in a FMS (Facility Management System, not shown). When following this example, the facility may include various meters, and the characteristics of each facility may include the physical quantity of the energy type, the capacity of the facility, the location of the facility, and the volume of the facility. The building energy management system can select a control point connected to the meter and energy use among control points that are set by connecting facilities and equipment characteristics, and generate the selected control point as a meter reading item.

The reason why the building energy management system according to the present invention generates a set point as a metering item in which the facility and facility-specific characteristics are connected is collected by remote metering data and manual metering collected by the remote metering as the metering item is unified. This is to label the manual reading data.

Accordingly, when a plurality of meter reading items are generated by the building energy management system, manual meter reading can be performed on the meter for manual meter reading by the remote meter and the meter for building operation according to the meter reading item. have.

Thereafter, the building energy management system acquires remote meter reading data obtained according to the remote meter reading and manual meter reading data acquired according to the manual meter reading for each meter reading item (S510). Accordingly, the building energy management system may acquire remote meter reading data obtained by remote meter reading and manual meter reading data acquired by manual meter reading for each meter installed for each zone of the building.

Thereafter, the building energy management system integrates the acquired remote meter reading data and manual meter reading data (S520). Specifically, the building energy management system records the remote meter reading data in the first data field and the manual meter reading data in the second data field to generate integrated data in which the remote meter reading data and the manual meter reading data are integrated into one data.

In one embodiment, the building energy management system may generate integrated data by integrating manual metering data into the remote metering data based on the remote metering time at which the remote metering data is acquired. At this time, the building energy management system may determine that it is collected at the same collection time when there is a difference within a predetermined time range between the remote meter reading time and the manual meter reading time, and may integrate the remote meter reading data and the manual meter reading data.

In one embodiment, the building energy management system includes the initialization occurrence information or the error occurrence information of the meter when integrating the remote reading data and the manual reading data, if there is a difference over a predetermined reference value between the remote reading data and the manual reading data. Integrated data can be created. At this time, the initialization occurrence information may be a flag indicating initialization, and the error occurrence information may be a flag indicating an error.

In one embodiment, the building energy management system determines that an error has occurred in the corresponding meter if the difference between the remote meter reading value of the remote meter reading data and the manual meter value of the manual meter reading data is greater than or equal to a predetermined first reference value, and an error occurs in the meter The flag indicating is recorded in the third data field to generate integrated data.

In one embodiment, if the difference between the remote meter reading value of the remote meter reading data and the manual meter reading value of the manual meter reading data is greater than or equal to a second predetermined reference value, the building energy management system determines that the meter has been initialized, and initializes the meter. The flag indicating the occurrence can be recorded in the third data field to generate integrated data. In this case, the second reference value may be greater than the first reference value.

As described above, since the building energy management system according to the present invention generates the integrated data by determining whether the meter is initialized or an error occurs through comparison between the remote meter reading data and the manual meter reading data, it is possible to know whether the meter is initialized or an error occurs. It has the effect of calculating the exact energy consumption.

The building energy management system uses the generated integrated data to calculate energy use for each zone of the building (S530). Specifically, the building energy management system extracts a value recorded in any one of the first data field and the second data field of the integrated data 430 according to a predetermined criterion to calculate energy consumption for each zone. At this time, the standard may be set by the user to either manual reading data or remote reading data for each zone.

Hereinafter, a method of calculating energy consumption will be described in more detail with reference to FIG. 6.

6 is a flow chart showing a method of calculating energy consumption according to an embodiment of the present invention.

The building energy management system calculates the first energy use of a public area commonly used by energy consumers occupying each area of a building according to the ratio of the area of the public area to the total area of the building (S600). Specifically, the building energy management system calculates the total energy consumption of all energy consumers by using the integrated data of the integrated meters in the area occupied by each energy consumer, and the public area compared to the total area of the building from the total energy consumption of all energy consumers. The first energy consumption of the public area can be calculated according to the area ratio of.

At this time, the energy consumer may include a tenant who is an office space rental customer or a tenant who is a commercial space rental customer.

Thereafter, the building energy management system calculates the second energy consumption of the area occupied by each energy consumer (S610). Specifically, the building energy management system may calculate the second energy consumption of each energy consumer using integrated data of the area occupied by each energy consumer.

Afterwards, the building energy management system, if there is a first energy consumer occupying an area where no meter is installed in the building area, the first energy supply amount in the common area and the second energy consumer installed meter in the total energy supply to the building. The value obtained by subtracting the summation result value of the second energy supply amount of each is estimated as the second energy consumption of the area occupied by the first energy consumer (S620).

Thereafter, the building energy management system calculates the third energy use of each energy consumer by distributing the first energy use of the common area to each energy consumer (S630). Specifically, the building energy management system allocates the first energy use of the common area according to the ratio of the area of each energy consumer to the total area of all energy consumers or the ratio of the sales of each energy consumer to the total sales of all energy consumers. Calculate the third energy consumption.

Thereafter, the building energy management system calculates the final energy consumption of each energy consumer by adding the third energy consumption calculated for each energy consumer to the second energy consumption of each energy consumer (S640).

For example, when the energy consumer is a tenant, the third energy usage is calculated by distributing the first energy usage in the common area according to the area ratio of each tenancy, and the third energy usage is added to the second energy usage of each tenancy. The final energy consumption of the tenant can be calculated. In addition, if the energy customer is an occupant, the third energy consumption is calculated by distributing the first energy use in the common area according to the sales ratio of each tenant, and adding the third energy use to the second energy use of each tenant. The final energy consumption of the tenant can be calculated.

Referring back to FIG. 5, the building energy management system may preview at least one of the area of each zone occupied by each energy consumer, the sales of the energy consumer, and the past energy usage of each zone, and the past energy usage trend of each zone. The energy consumption may be corrected by inputting a correction factor of a predetermined correction formula and inputting energy consumption calculated for each zone as a correction parameter of the correction formula (S540).

Here, the area may be the ratio of the area of each district to the total area of the building, and the sales may be the ratio of the sales of each energy consumer to the total sales of all energy consumers.

For example, the building energy management system can correct the energy use of each occupant according to the area ratio of each occupant when the energy consumer is a tenant, and the energy use of each tenant according to the sales ratio of each tenant if the energy consumer is the tenant Can be corrected.

In addition, the building energy management system may correct the energy usage by using the energy usage and energy usage trend of the previous month, energy usage and energy usage trend of the same month of the previous year, and energy usage and energy usage trend of the same month of the previous year.
