The building network may be connected to the external energy management server 100 through a router. In another embodiment, each gateway 210 to 216 may be directly connected to the energy management server 100 through the Internet. Hereinafter, for convenience of explanation, when the gateways 210 to 216 are connected to the energy management server 100 through a building network and a router, and the gateways 210 to 216 are directly connected to the energy management server 100 without a building network. In all cases, it is expressed that the gateways 210 to 216 are connected to the energy management server 100 .

In the building 200, at least one or more first measuring instruments 220 and 222 for measuring power generation, at least one or more second measuring instruments 224, 226 and 228 for measuring consumption by energy source, and at least one or more third measuring instruments 230 and 232 for measuring consumption by use may exist. For example, the 1-1, 1-2 measuring instruments 222 are respectively connected to facilities that produce renewable energy such as solar, geothermal, and wind power to measure the amount of power generation, and 2-1, 2-2, 2-3 measuring instruments (224,226,228) are installed in water/switchboard, gas pipe, hot water pipe, etc. to measure consumption by energy source such as electricity usage, gas usage, hot water usage, etc., and 3-1,3-2 measuring instruments (230,232) are It is connected to various facilities such as transportation means such as lighting, electric heaters, air conditioners, and elevators, so that the power consumption for each purpose can be measured. The 1-1, 1-2 measuring instruments 220 and 222 each exist for each type of renewable energy, the 2-2, 2-2, 2-3 measuring instruments 224, 226 and 228 exist for each energy source, respectively, and the 3-1 measuring instrument 230 may be implemented as a multi-channel meter to measure energy consumption for a plurality of different uses. The measuring instruments 220-232 are watt-hour meters and integrated calorimeters depending on the measurement target. It can be implemented with a digital meter, a flow meter, etc. The type and number of measuring instruments in a building may be variously modified according to embodiments.

A plurality of gateways 210 to 216 may exist according to the type of information measured by the measuring instruments 220 to 232 (energy production, consumption by energy source, consumption by use, etc.). In one embodiment, the first gateway (210, 212) is located between the first measuring instrument (210, 212) and the energy management server 100 for measuring the amount of power generation by type of new and renewable energy, the amount of renewable energy collected from the first measuring instrument (220, 222) information on the energy management server 100 may be transmitted. The second gateway 214 is located between at least one or more second measuring instruments 224, 226, 228 for measuring energy consumption by energy source and the energy management server 100, and information on consumption by energy source collected from the second measuring instruments 224, 226, 228 It can be transmitted to the energy management server (100). The third gateway 216 is located between at least one or more third measuring instruments 230 and 232 for measuring energy consumption by use and the energy management server 100, and collects information about energy consumption by use from the third measuring instruments 230 and 232. It can be transmitted to the management server (100).

In another embodiment, one gateway may collect at least two or more different types of information among energy production, consumption by energy source, and consumption by use and transmit it to the energy management server 100 . For example, after the first gateway 210 collects all energy production and consumption information for each energy source, it may transmit it to the energy management server. To this end, information on instruments interworking with each gateway (eg, information on instruments connected for each gateway serial channel) may be pre-registered in the energy management server 100 .

To this end, each gateway 210 to 216 may pre-define the type of measurement information received from each connected measuring instrument 220 to 232 .

The communication methods of the plurality of measuring instruments 220 to 232 in the building 200 may all be the same or some may be different from each other. Alternatively, the communication methods of the instruments of the building A and the building B may be the same or some may be different from each other. In other words, the communication methods of the measuring instruments present in the buildings 110 managed by the energy management server 100 may not all be the same. For example, the first measuring instrument 220 may use the RS-232 communication method, the second measuring instrument 224 may use the Zigbee communication method, and the energy management server may use the Internet communication method. In this case, a gateway 210 intermediary between the RS-232 communication method and the Internet communication method is required between the first measuring instrument 220 and the energy management server 110 , and the second measuring instrument 224 and the energy management server 100 are required. ), a gateway 214 for intermediary between the Zigbee communication method and the Internet communication method is required. When the measuring instruments 220 to 232 of various communication methods exist in the building 200, different types of gateways supporting different communication methods for each of them are required. Moreover, when a plurality of buildings 110 exist as shown in FIG. 1 , more various types of gateways that intermediary between heterogeneous networks may be required. However, when each gateway supporting each communication network is purchased or individually manufactured, there may be a problem in that it takes a lot of time and money to construct a network in a building. In order to solve this problem, the present embodiment provides a gateway capable of supporting a plurality of different communication methods, which will be described in detail with reference to FIGS. 14 to 20 .

Also, some components may be omitted or other components may be further added according to embodiments.

The integrated monitoring unit 310 receives and stores information on energy production, consumption, and usage from each gateway of the building, and information about at least one of an energy usage target value, energy production, energy consumption, consumption status by energy source, and consumption status by use is integrated and displayed. In one embodiment, the integrated monitoring unit 310 may receive and set the target energy usage from the manager, then determine how much the real-time energy usage reaches the target value and display it on the integrated monitoring screen. An example of the integrated monitoring screen provided to the building manager terminal is shown in FIG.

The intended use of electricity at the time the gateway is installed may change over time. For example, the use of electricity measured by the measuring instrument may vary according to a change in wiring of an electric line, new installation or removal of various facilities, or movement of a location. In the example of FIG. 2 , the heating device connected to the measurement point measured by the 3-1 meter 230 may be changed to a ventilation hole. When such a change occurs, the administrator can reflect the change in the use of electricity measured by the instrument in the network environment information. However, in order to solve the problem of the manager reflecting these changes one by one and to solve the problem of omission of reflecting the changes, the energy analysis unit 320 may automatically determine whether the energy use purpose has been changed as an energy use pattern. For example, since the electricity usage pattern of the air conditioner and the electricity usage pattern of lighting may be different from each other, the energy analysis unit 320 pre-prescribes a reference pattern (eg, usage pattern for each purpose for a certain period in the past) for usage by purpose. It is possible to automatically determine whether the purpose of the energy use collected by the measuring instrument has changed by comparing the energy use pattern and the reference pattern collected over a recent period from the measuring instrument that stores and measures the amount of use by purpose.

In another embodiment, the facility information providing unit 350 may receive and provide status information of various instruments and gateways in the building.

The information monitoring unit 360 provides the status of occurrence of an event including a failure or warning of equipment in a building for a certain period of time. An example of a screen provided by the information monitoring unit 360 is illustrated in FIG. 12 .

In another embodiment, the information monitoring unit 360 automatically detects an abnormality in facilities such as water or electricity (eg, water leakage, short circuit, etc.) using the energy usage pattern and notifies the administrator (eg, an alarm to the administrator terminal) can be sent). For example, the information monitoring unit 360 may determine that an abnormality has occurred and notify the manager when values such as the amount used by energy source and the amount used by each use are suddenly changed out of a predefined range. In order to detect the occurrence of an abnormality, the standard of usage by energy source/use may be variously modified according to embodiments.

The environment information providing unit 370 provides surrounding environment information including indoor and outdoor temperatures. The surrounding environment information provided by the environment information providing unit 370 may be displayed on each screen of FIGS. 4 to 13 .

The control management unit 380 controls various facilities, measuring instruments, or gateways in the building. For example, when the control management unit 380 receives an indoor temperature control command from the manager or a preset condition occurs, it generates a control signal to control the indoor temperature in the building to generate a control signal for the corresponding equipment (air conditioner, blower, air conditioner, heater) in the building. etc.) can be forwarded. In addition to this, various methods for controlling various facilities may be applied to the present embodiment.

The energy trading platform 390 provides an energy trading platform for energy trading between a plurality of buildings. For example, the energy trading platform 390 provides a platform for the sale or purchase of new and renewable energy produced or stored in each building. Buildings that have a lot of new and renewable energy production can register the energy sales information of the surplus on the energy trading platform.

In addition to this, the energy management server 100 may further include a configuration for automatically setting the network of FIG. 21 and/or managing the instrument memory map of FIG. 22 . For example, it may further include a configuration of a network setting unit that performs the automatic network setting method of FIG. 21 and/or a memory map management unit that performs the memory map management method of FIG. 22 .

21 is a diagram illustrating an example of a network setting method for constructing a zero-energy building according to an embodiment of the present invention.

Referring to FIG. 21 , the energy management server 100 stores network environment information, such as the installation location of the meter and the gateway in the building, and the connection relationship between the meter and the gateway (that is, information on the instrument connected to each channel of the gateway), such as a manager, etc. It is registered from and stored in the database (S2100). In one embodiment, the energy management server 100 is a type of measuring instrument (manufacturer/model, identifier, etc.) connected to various facilities (energy production facility or energy consumption facility, etc.) in a building, a baud rate for serial communication ), the measurement location of the measuring instrument (eg, renewable energy power generation facilities, water/switchboard, electric heater, etc.), the type of information the measuring instrument measures (eg, energy production, consumption by energy source, consumption by use), gateway Network environment information such as an identifier, a gateway installation location, and a connection relationship between the gateway and the instrument can be stored in advance in the database. The type or number of information included in the network environment information may be variously modified according to an embodiment.

The energy management server 100 may generate and output an on-site installation manual for installation and connection of a meter and a gateway in a building based on the network environment information stored in the database. For example, the energy management server 100 may output an on-site installation manual in which the installation location of a meter and a gateway for each floor of a building is displayed on a floor plan for each floor. Operators can install instruments and gateways using the on-site installation manual. When the measuring instrument and the gateway are installed and connected, a network between facilities (eg, new and renewable energy generation facilities, lighting, electric heating appliances, etc.), measuring instruments, gateways, and energy management servers is established as shown in FIG. 2 . In another embodiment, the meter and the gateway are pre-installed in the building, and the energy management server 100 may register and store network environment information such as the meter and the gateway installed in the building.

The energy management server 100 transmits network setting information including a type of a measuring instrument to be interlocked with each gateway, a measuring point, and the like (S2110). As an example, the network setting information includes the type of instrument connected to the channel of each gateway, measurement point, baud rate, information to be read from the connected instrument (eg, the memory map information of FIG. 22 ), instrument identifier , and may include information such as a measurement point identifier. For example, the gateway automatically connects to the energy management server based on the preset and stored address information (eg, IP address, etc.) of the energy management server and transmits its identifier (ie, gateway identifier) to the energy management server. And, the energy management server may transmit network setting information such as a measuring instrument connected to the corresponding gateway to the corresponding gateway based on the identifier of the accessed gateway.

When installing the gateway, the operator can directly input the information of the instrument connected to the gateway or the information to be collected from each instrument into the gateway at the site to set it. However, there are many gateways in the building, and since the types or number of connected instruments and the types of information to be collected are different for each gateway, many errors may occur when an operator enters the gateway one by one in the field.

Accordingly, in this embodiment, each gateway automatically establishes a connection with the measuring instrument by identifying the type of measuring instrument connected to itself and the type of information measured by each instrument based on the network setting information received from the energy management server ( S2120). For example, referring to FIG. 2 , the second gateway 214 is an identifier of three second instruments 224, 226, 228 from the energy management server 100, and a measurement point (number/switchboard, By receiving and storing network setting information such as the identifier of gas pipe, hot water pipe, etc.) Settings for connection with the instruments 224 , 226 , and 228 can be automatically completed.

Each gateway collects information from the connected instrument and transmits it to the energy management server (S1230). For example, referring to FIG. 2 , the second gateway collects energy consumption by energy source from the second meter according to the network setting information received from the energy management server 100 , and then transmits it to the energy management server.

As an embodiment, a function for interworking with the instrument may be added to the firmware of each gateway so that each gateway can receive information from the instrument. For example, if instruments of model A and model B are connected to the gateway, functions for communication with model A and model B and information collection may be added to the firmware of the gateway, respectively. However, in this case, since each function for interworking by instrument model must be additionally developed in the firmware of the gateway, a lot of time and cost are incurred.

As a method for solving this problem, the energy management server 100 may use memory map information for each instrument model. A method of managing the memory map for each instrument model will be described again with reference to FIG. 22 .

22 is a diagram illustrating an example of a method for managing a memory map of an instrument according to an embodiment of the present invention.

Referring to FIG. 22 , the energy management server 100 stores and manages memory map information for at least one or more instruments 2210 , 2212 , and 2214 connected to the gateway 2200 in a database. Three different models of measuring instruments 2210 , 2212 , and 2214 may be connected to the gateway 2200 through the first to third channels. Most instruments use a standard interworking protocol such as modbus for serial communication such as RS485, but the data management method (ie, memory map management method) for each manufacturer/model may be different.

The energy management server 100 registers and stores the memory map information (information such as the address of the memory to be read from the instrument, data length, data type, etc.) for each instrument model, not the firmware, from an administrator, etc., and stores it, and provides each gateway to each gateway. Provides memory map information for each model of the instrument connected to it.

If the models of the instruments (2210, 2212, 2214) connected to each channel of the gateway 2200 are all different, the energy management server 100 provides memory map information for the instruments (2210, 2212, 2214) of three different models. and the like may be provided to the gateway 2200 . For example, when instrument A is connected to the first channel of the gateway, the energy management server 100 stores memory map information about instrument A stored in the database (accumulated power amount of 8 bytes 'long' type in memory address 30001, information such as an instantaneous power amount of 2-byte 'int' type) at the memory address 30011) is provided to the gateway 2200 .

The gateway 2200 may collect necessary information by requesting and receiving information stored in a specific location of the memory of the corresponding instrument by using the memory map information for each instrument model. For example, the gateway 2200 reads the accumulated power amount information stored in the 8-byte 'long' type in the memory address 30001 of the A meter using the memory map information of the A meter received from the energy management server 100, and then It can be transmitted to the energy management server (100).

If the A meter 2210 connected to the first channel of the gateway 2200 is replaced with a D meter of another model afterward, the energy management server 100 transmits the information of the instrument connected to the first channel of the gateway 2200 to the D instrument. Information (model, baud, type, memory map, etc.) can be changed and stored, and memory map information of the D instrument can be transmitted to the gateway 2200 .

The present invention can also be implemented as computer-readable codes on a computer-readable recording medium. The computer-readable recording medium includes all types of recording devices in which data readable by a computer system is stored. Examples of the computer-readable recording medium include ROM, RAM, CD-ROM, SSD storage device, optical data storage device, and the like. In addition, the computer-readable recording medium is distributed in a network-connected computer system so that the computer-readable code can be stored and executed in a distributed manner.

So far, with respect to the present invention, the preferred embodiments have been looked at. Those of ordinary skill in the art to which the present invention pertains will understand that the present invention can be implemented in a modified form without departing from the essential characteristics of the present invention. Therefore, the disclosed embodiments are to be considered in an illustrative rather than a restrictive sense. The scope of the present invention is indicated in the claims rather than the foregoing description, and all differences within the scope equivalent thereto should be construed as being included in the present invention.
