Additionally, it should be understood that the location or arrangement of individual components within each disclosed embodiment may be changed without departing from the spirit and scope of the invention. Accordingly, the detailed description set forth below is not to be taken in a limiting sense, and the scope of the present invention, if properly described, is limited only by the appended claims, along with all equivalents as claimed by those claims. Like reference numbers in the drawings indicate the same or similar function throughout the various aspects.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily practice the present invention.

1 is a diagram showing a schematic configuration of a building management system according to an embodiment of the present invention.

The building management system 1 of the present invention can measure conditions within a building and control related facilities according to the measured conditions. In addition, the building management system 1 of the present invention can measure energy consumption in a building.

The condition within the building may include at least one of temperature, humidity, carbon dioxide concentration, air quality, pressure, and flow rate. In addition, energy for measuring usage may include at least one of water, domestic hot water, heat, electric power, and gas.

Facilities included in the building include at least one of a pump, an air conditioner, a refrigerator, a cooling tower, a boiler, and a heat exchanger, but are not limited thereto and may further include various facilities.

In addition, the building management system 1 may include a gateway (G/W) 10, a wired direct digital controller (DDC), an LCP panel, and a wireless mesh network. In addition, the building management system 1 may further include a management server 100 .

At this time, the wireless mesh network performs mutual communication using a radio frequency of 900 MHz band, and may include a wireless DDC, a plurality of wireless repeaters, and a plurality of measurement systems.

Each of the plurality of measurement systems measures the state of at least one of environmental conditions such as temperature, humidity, carbon dioxide concentration, air quality, pressure, and flow rate in the area where the measurement system is located in the building, and/or at least one of energy such as water supply, domestic hot water, heat, electricity, and gas. There may be a measurement system communication module capable of measuring one amount of usage and transmitting the measured state-related data to a location inside or adjacent to the measurement system, and a sensor and/or meter indicating a measured value.

For example, a sensor for detecting a human body may include at least one sensor for determining the presence or absence of an object, such as an ultrasonic sensor or an infrared sensor. In addition, in the case of a sensor for measuring pressure, it may be configured to include at least one sensor for measuring pipe pressure, duct pressure, and the like.

As can be seen with reference to FIG. 1, the wired DDC of the building management system 1 of the present invention performs facility control while communicating with at least one of installed facilities such as a pump, an air conditioner, a refrigerator, a cooling tower, a boiler, and a heat exchanger. The wired DDC or LCP panel can support control of power/lighting facilities while communicating with electronic switchboards, switchboards, lighting, etc.

In addition, the wireless DDC communicates with wireless repeaters and measuring instruments (temperature, humidity, carbon dioxide concentration, air quality, pressure, flow rate, water supply, domestic hot water, calorific value, power, gas, etc.) to determine the status of the area in the building where the measuring instrument is located and/or It can assist in carrying out monitoring of energy usage.

In particular, the wireless DDC receives data measured in each of a plurality of measurement systems, forms a wireless mesh network with each other using a radio frequency of 900 MHz band, and sends the measured data to the gateway 10 through the formed wireless mesh network. can be conveyed

Since the plurality of measurement systems form a wireless mesh network by being signal-connected to other measurement systems adjacent to each other at a radio frequency of the 900 MHz band having a coverage distance of about 1 km, even when installed in a place enclosed in a building or in a place with scattered obstacles, wireless operation is performed smoothly. Communication is possible, and installation costs can be reduced because it does not have to be installed so as to be exposed to a wall.

2 is a block diagram illustrating a wireless mesh network connection structure according to an embodiment of the present invention.

The wireless DDC includes a wireless DDC communication unit, a wireless DDC control unit, and the like, wherein the wireless DDC communication unit operates as a base station (BS) that collects and uploads measured data, and the plurality of measurement systems and the wireless DDC communication unit may form an N:1 mesh network.

As can be seen in FIG. 2, the wireless mesh network in the building management system 1 of the present invention has a BS, and each measurement system that is an end node can transmit data to the wireless DDC communication unit (BS) . Here, the measurement system communication module included in the measurement system may operate as a sensor network relay station (SNRS) within the wireless mesh network.

In addition, the wireless DDC may use both a polling method and an event driven method in collecting measurement data of each of a plurality of measurement systems. However, when the volume of measurement (meter reading) data is small and the meter reading cycle is long (eg, once a day), such as energy consumption measurement, the polling method can be advantageous because it can avoid data collision.

3 is a diagram showing a schematic diagram for explaining a wireless mesh network communication operating method of a building management system according to an embodiment of the present invention.

Referring to FIG. 3, the data flow between the wireless DDC and the measurement system is shown, and the measurement (meter reading) command ($Wrdp1 = 37:<FA>: 1) output from the control unit of the wireless DDC is transmitted by the wireless DDC communication unit (BS). Upon receipt, the BS can transmit Rd-pkt (Report Downlink Packet) including the measurement command or broadcast Bd2-pkt (Broadcasted Downlink 2 Packet).

Upon receiving this, the communication module (SNRS) of the measurement system may send a measurement command to a sensor and/or meter of the measurement system, collect the result, and transmit it to the BS in the form of Ru-pkt.

In order for the wireless DDC to measure (read) the value of a sensor and/or meter of a specific measurement system, a routing path from the BS to the communication module of the corresponding measurement system must be formed. For example, in order for the command signal of the wireless DDC control unit to be transmitted to the measurement system, a downlink path must be formed between the BS and the measurement system communication module. There should be.

To form the uplink path, the BS broadcasts a short packet called Bd1-Pkt (Broadcasted Downlink1 Packet) in the form of broadcasting, and measurement system communication modules, which are SNRS connected to each sensor and/or meter, receive it and update the uplink table, Uplink tables of all SNRSs in the network can be updated by rebroadcasting Bd1-Pkt after increasing hops if necessary.

On the other hand, when a packet is transmitted from the measurement system communication module (SNRS) of a specific measurement system to the BS, the downlink from the BS to the measurement system communication module (SNRS) is naturally updated in the downlink table of the measurement system communication module (SNRS). Therefore, in order to form a downlink path, data reception from the measurement system must be performed at least once so that a command signal transmitted thereafter can be transferred from the BS to the measurement system communication module (SNRS).

4 is a schematic diagram for explaining an operating principle in which uplink and downlink are formed between a wireless DDC and a measurement system according to an embodiment of the present invention.

The measurement is performed by a simple data acquisition procedure in which a measurement (meter reading) command is sent from the wireless DDC to the measurement system and the result is received. For this purpose, the first method is a specific measurement system communication module (a) as shown in FIG. SNRS) to determine whether the downlink path (address) is registered, and if the path is already registered, Rd-pkt (Report Downlink Packet) can be transmitted to the measurement system communication module (SNRS). Otherwise, if broadcasting is performed with CMD set to 19 during Bd2-pkt (Broadcasted Downlink2 Packet), the measurement system communication module (SNRS) receives it and transmits a simple message to the BS, and then a downlink path is formed.

On the other hand, as a second method, as shown in (b) of FIG. 4, if a measurement (meter reading) command (37 in the embodiment) is loaded on Bd2-pkt and transmitted without determining whether a downlink table is formed, the corresponding measurement system The communication module (SNRS) recognizes this and operates in a manner of immediately reporting meter reading data. The second method may be easier and more effective than the first method if the number of measurement systems is not large (eg 1000).

Meanwhile, a wireless repeater of a bridge concept can be placed between the wireless DDC and the measurement system to distribute the traffic load, and functions related thereto will be reviewed together in FIGS. 12 and 13 to be described later.

5 is a diagram showing a schematic configuration of a management server according to an embodiment of the present invention.

As shown in FIG. 5, the management server 100 of the present invention includes a communication unit 110 and a processor 120, and may not include a database 130 unlike FIG. 5 in some cases. At this time, the management server 100 may be connected to a separate and independent database through a communication unit. The management server 100 is a device for collecting and analyzing state and/or energy management information of areas within a building, and may correspond to a Building Energy Management System (BEMS) for building a zero-energy building.

The management server 100 may transmit and receive information to and from the manager terminal 200 through the communication unit 110, and the communication unit 110 of the management server 100 may be implemented with various communication technologies. For example, Wi-Fi (WIFI), WCDMA (Wideband CDMA), HSDPA (High Speed Downlink Packet Access), HSUPA (High Speed Uplink Packet Access), HSPA (High Speed Packet Access), Mobile WiMAX (Mobile WiMAX), WiBro ( WiBro), LTE (Long Term Evolution), 5G, 6G, Bluetooth, infrared data association (IrDA), NFC (Near Field Communication), Zigbee, wireless LAN technology, serial communication such as RS485 protocols, etc. may be applied. In addition, when connecting to the Internet and providing services, TCP/IP, which is a standard protocol for information transmission on the Internet, may be followed.

Next, the database 130 of the present invention may store information on the state and/or energy consumption of areas within a building. In the case of using an external database, the management server 100 may access the external database and transmit/receive data through the communication unit 110 as described above.

In addition, looking at the manager terminal 200, it is provided with a memory means and equipped with a microprocessor while performing communication, such as a desktop computer, a notebook computer, a workstation, a PDA, a web pad, a mobile phone, a smart remote controller, and various IoT main devices. Thus, any digital device equipped with an arithmetic capability may correspond to a terminal according to the present invention.

In addition, although FIG. 5 shows only one management server 100 as a central monitoring role, in some cases, a central control device (or central control server) for facility control and a central control server for power/lighting control with a central monitoring role. It is also possible to separate functionally in operation with a control device (or central control server), BEMS, etc. However, only the structure is different, and the function will be the same or similar.

6 is a diagram illustrating a process of controlling facilities included in a building through a wired DDC according to an embodiment of the present invention.

The building management system 1 and/or the management server 100 may process to measure (S601) conditions (temperature, carbon monoxide concentration, human body detection) of areas within the building through a measuring system included in the wireless mesh network. . However, without being limited thereto, the building management system 1 and/or the management server 100 may be configured to measure various conditions within the building, such as humidity, carbon dioxide concentration, air quality, pressure, and flow rate.

Specifically, the building may be divided into zones (eg, basement 1 (B1) floor, 1st floor, 2nd floor, conference room, office, lobby, parking lot, etc.), and the management server 100 may measure the status for each zone. can For reference, the method of dividing the zone may vary, and may be divided according to each floor such as the first floor and the second floor, or may be divided according to a divided place such as a meeting room and a lobby. In some cases, the condition of a plurality of buildings may be measured by dividing one building into one zone.

At this time, if the zone is composed of a plurality of zones, the same type of state may be measured for each of the plurality of zones (eg, temperature and human body detection in the first zone, temperature and human body detection in the second zone) measurement), and different conditions can be measured for each zone (e.g. temperature measurement in a conference room, human body detection measurement in a lobby).

According to various embodiments, the first zone and the second zone may overlap. For example, in a specific area (eg, a parking lot), a first area and a second area may include overlapping areas.

In this regard, FIG. 7 is a diagram of a specific area managed through the building management system 1 and a wireless network configured therein.

Referring to FIG. 7, a measuring system installed in a specific area and a wireless network including the measuring system include a wireless repeater 711, a wireless DDC 713, a gateway 10, a wired DDC 715, and a facility 717. can do.

Here, the gateway 10, the wired DDC 715, and the equipment 717 may be wired connected. In addition, a wireless DDC may also be connected to the gateway 10 by wire.

Sensors and/or meters constituting the measurement system are described as including sensors for temperature, carbon monoxide concentration, and human body detection, but are not limited thereto, and may include sensors for measuring various conditions in a building, such as an illuminance sensor. there is.

A plurality of measurement systems including a measurement system 701 and a measurement system 703 may be configured in a specific area.

State data measured through a plurality of measuring systems may be transmitted to a wireless DDC through a wireless mesh network. At this time, when the wireless repeater 711 is composed of two or more including a first wireless repeater and a second wireless repeater, state data measured through a plurality of measurement systems is transmitted wirelessly through the first wireless repeater and/or the second wireless repeater. It can be passed to DDC 713.

The gateway 10 may receive status data for an area from a wireless DDC included in a wireless mesh network (S603).

Specifically, the zone includes at least a first zone and a second zone, the wireless repeater 711 is composed of a plurality of repeaters including at least the first wireless repeater and the second wireless repeater, and the plurality of measurement systems includes at least the first wireless repeater 711. It can be assumed that the measurement system 701 and the second measurement system 703 are included.

At this time, as shown in FIG. 1, the wireless DDC 713, the first wireless repeater, and the second wireless repeater form an upper mesh network, and the first wireless repeater and the first measurement system 701 form a first lower mesh network. A network is formed, and the second wireless repeater and the second measuring system 703 may form a second lower-level mesh network.

For reference, in the present invention, the first lower-level mesh network may measure a state in a first region, and the second lower-level mesh network may measure a state in a second region.

As a result, the wireless DDC 713 acquires the first state data for the first area obtained by the first measurement system 701 from the first wireless repeater and transmits the obtained data to the gateway 10, and the second measurement system acquires The second state data for the second zone can be acquired from the second wireless repeater and transmitted to the gateway 10 .

The gateway 10 may transmit the received state data to a matched specific wired DDC (S605). Here, the wired DDC 715 may include a plurality of wired DDCs including a first wired DDC and a second wired DDC.

For example, in the database of the gateway 10, first state data (eg, temperature data) is matched with a first wired DDC, and second state data (eg, carbon monoxide concentration data) is matched with a second wired DDC. It may be in a state set to be matched.

Among state data obtained from a plurality of measurement systems, the gateway 10 may transmit first state data to a first wired DDC and second state data to a second wired DDC.

According to another embodiment, when the first state data and the second state data are data (eg, temperature data) obtained by measuring the same type of state (eg, temperature), the gateway 10 may determine the first state data and the second state data. It can be transmitted to one wired DDC that matches the state data. However, the first state data and the second state data may be transmitted to another wired DDC that matches each of the first state data and the second state data obtained by measuring the same type of state (eg, temperature).

For example, the first state data is temperature data measured in a first zone, the second state data is temperature data measured in a second zone, and the first state data is a first wired DDC connected to an air conditioner in the first zone. , and the second state data may be in a state matched with the second wired DDC connected to the air conditioner in the second zone.

At this time, the gateway 10 may transmit the first state data to the first wired DDC and the second state data to the second wired DDC.

A specific wired DDC, which may correspond to any one of the first wired DDC and the second wired DDC, can control at least one facility connected to the specific wired DDC based on received state data and at least one algorithm ( S607).

In each wired DDC, a setting value for a matched state may be set. For example, a first set value for the first state data may be set in the first wired DDC, and a second set value for the first state data may be set in the second wired DDC.

Here, the setting value is expressed as a value, but is not limited thereto and may be set as a range. Also, depending on the case, a plurality of setting values may be set in the wired DDC. That is, a plurality of setting values may be set in one state data.

A setting value set in each wired DDC may be set or changed based on user input. For example, the management server 100 may be configured to set or change a setting value of a wired DDC. The management server 100 may receive a user input for setting or changing a setting value of a specific wired DDC, and may set or change the setting value of a specific wired DDC based on this.

Each wired DDC may determine whether or not to control the connected equipment based on the received state data. For example, each wired DDC compares the received state data with a set value, or inputs state data into a calculation formula set (or programmed) in each wired DDC and compares the calculated value with the set value. equipment can be controlled.

Here, the calculation formula may correspond to at least one algorithm for obtaining a calculation value using state data as an input value. The wired DDC may include at least one algorithm for obtaining a calculated value and/or at least one algorithm for setting or changing a set value.

For example, the first wired DDC compares the first state data or a first calculation value calculated based on the first state data with a first set value set in the first wired DDC, and When the calculated value deviates from (or has a difference, hereinafter deviates from) the first set value, controls the connected equipment so that the first state data or the first calculated value meets (or reaches, hereinafter satisfies) the set value, When the first state data or the first calculation value does not deviate from (or satisfies) the first set value, the connected facility may be controlled to maintain the current state.

More specifically, when the first wired DDC confirms that the first state data or the first calculated value is higher than the set value, the first state data or the first calculated value satisfies the set value or the set value is within the range ( setting range), the facility connected to the first wired DDC sets the calculated value so that the first state data or the first calculated value satisfies the set range (eg, so that the first state data or the first calculated value is within the set range). lowering control can be performed.

In addition, when the first wired DDC confirms that the first state data or the first calculated value is lower than the set value, the first state data or the first calculated value reaches the set value or the set value is within the range of the first state data. A facility connected to the first wired DDC may perform control to increase the calculated value so that the data or the first calculated value is located within a set range.

In addition, the first wired DDC may be used when the first state data or the first calculated value satisfies the set value (when the set value is within a range, the first state data or the first calculated value is within the set range), the first state data or Equipment connected to the first wired DDC may be turned off or controlled in a standby state to maintain the first calculated value.

According to an embodiment, when the first state data is temperature data and the facility 717 connected to the first wired DDC 715 is a cooler or heater of an air conditioner, the first wired DDC 715 is the first state data or When the first calculated value is higher than the set value, the air conditioner may be operated so that the first state data or the first calculated value satisfies the set value, and when the first state data or the first calculated value is lower than the set value, the first state The heater may be operated so that the data or the first calculated value satisfies the set value, and the air conditioner may be turned off or the blower may be operated when the first state data or the first calculated value satisfies the set value.

However, the present invention is not limited thereto, and on the contrary, the first wired DDC compares the first state data or the first calculation value calculated based on the first state data with the first set value set in the first wired DDC, and When the data or the first calculated value is out of the first set value, the connected equipment is turned off or controlled to maintain the first state data or the first calculated value, and the first state data or the first calculated value is set to the first value. If it does not deviate from the set value, it may be possible to control the connected facility to turn on or deviate from the first state data or first calculated value.

The above-described first wired DDC and related embodiments may be applied in the same or similar manner to other wired DDCs such as the second wired DDC.

For example, when the second state data is carbon monoxide concentration data and the facility 717 connected to the second wired DDC is a ventilator and an air conditioner of an air conditioner, the gateway 10 matches the second state data to the second wired DCC. The second wired DDC may compare the second state data or the second calculated value with the first set value, and control the ventilator and/or the air conditioner of the air conditioner according to the comparison result.

Also, according to an embodiment of the present invention, the processor 120 of the management server 100 may set or change calculation formulas and/or set values set in the plurality of wired DDCs. That is, the management server 100 can set, change, and/or reset the calculation formula (program) and/or set value of each of the plurality of wired DDCs based on an input from the connected manager terminal 200. .

In addition, even if the same state data is received, the control of facilities (eg, air conditioners including at least some of ventilation fans, air conditioners, and heaters, etc.) connected to a specific wired DDC may also vary according to the set calculation formula and/or set values.

In addition, when the processor 120 of the management server 100 issues a command to the wired DDC to turn off the facility even when the state data is out of a preset setting value and the connected facility is scheduled to be turned on. The facility can be controlled off.

The processor 120 of the management server 100 may receive set values, calculated values, and state data (obtained from a measurement system), etc. set from each of a plurality of wired DDCs, and transmit them to the manager terminal 200, At least one facility may be turned on or off by having a manager directly transmit a command to each of a plurality of wired DDCs.

As described above, a plurality of measurement systems 701 and 703 may exist in any one zone, and a plurality of state data measured in each is transmitted through the wireless repeater 711, the wireless DDC 713, and the gateway 10. It can be delivered to the matching wired DDC 715.

At this time, it can be assumed that the plurality of measurement systems include the first measurement system 701 and the second measurement system 703, and the plurality of state data includes first state data and second state data.

Referring to FIG. 7 , although three first measurement systems 701 and three second measurement systems 703 are shown, the number of measurement systems constituting the first measurement system and/or the second measurement system is not limited thereto. will be able to change

According to an embodiment of the present invention, an average value of three first state data measured from the first measurement system 701 can be extracted by a calculation formula set (or programmed) in the first wired DDC, and 1 wired DDC can control facilities connected to the first wired DDC through comparison with the set first set value.

Similarly, the average value of the three second state data measured from the second measuring system 701 can be extracted by a calculation formula set (or programmed) in the second wired DDC, and the second wired DDC is 2 It is possible to control equipment connected to the 2nd wired DDC through comparison with the set value.

For reference, according to the above examples, an air conditioner is described as an example of a facility 717 connected to a wired DDC 715, but other facilities (eg boilers, heaters, etc.) It may be connected to (715).

In addition, according to another embodiment of the present invention, any one state data among the three first state data exceeds the set first set value (or less than), and the first wired DDC may control the connected facilities.

In addition, according to another embodiment of the present invention, a predetermined number or more of a plurality of status data received at a specific time point from the gateway 10 by at least one algorithm set (or programmed) in a specific wired DDC is in an on state. Once you confirm that it is, you can control the connected equipment.

According to various embodiments, the number of the plurality of first measurement systems included in the first lower-level mesh network (eg, 3) and the number of the plurality of second measurement systems included in the second lower-level mesh network (eg, 3) ) may be a state recorded in the database corresponding to the gateway.

The gateway 10 receives a plurality of first state data for the first area acquired by the first wireless repeater through the wireless DDC, and records the number of first measurement systems and the first status data recorded in the database of the gateway 10. It is possible to determine whether there is an error in the first lower-level mesh network by comparing the number of data.

For example, when receiving first state data measured at a specific point in time, the gateway 10 compares the number of received second state data with three, which is the number of first measurement systems recorded in the database, and the comparison result is If they are not the same, it is possible to determine a communication failure of at least one of the first measurement systems and/or a measurement system failure.

Similarly, the gateway 10 receives a plurality of second state data for the second zone acquired by the second wireless repeater, and calculates the number of second measurement systems and the second state data recorded in the database. By comparing the numbers, it may be determined whether there is an abnormality in the second lower-level mesh network.

For example, when receiving the second state data measured at a specific point in time, the gateway 10 compares the number of received second state data with three, which is the number of second measurement systems recorded in the database, and the comparison result is If they are not the same, it is possible to determine a communication failure of at least one of the second measurement systems and/or a measurement system failure.

According to an embodiment of the present invention, the wired DDC receiving state data from the gateway 10 transmits the received state data to the management server 100, and the management server 100, based on the received state data, It is possible to determine whether or not the measurement system is abnormal.

For example, the database 130 of the management server 100 may store information on measurable values of each measurement system. That is, the management server 100 can also check the value that the state data transmitted by the wired DDC receiving the state data measured by the measuring system can have.

The management server 100 determines whether the value of the state data transmitted from the wired DDC is a value that the state data of the wired DDC can have, and if the state data of a value that cannot be obtained is confirmed, the state data is measured. It can be determined that an error has occurred in one measuring system.

According to various embodiments, the building management system 10 may include at least one measuring system capable of measuring at least a portion of water consumption, electricity consumption, and heat consumption in at least one zone. Energy consumption measured through a measurement system in a building may be transmitted to the gateway 10 through a wireless mesh network.

The energy usage amount received by the gateway 10 may be transmitted to the management server 100 . For example, energy usage may be in a state in which a matching wired DDC is not set. When the gateway 10 receives data for which a matching wired DDC is not set, that is, energy consumption, it may transmit the data to the management server 100 .

According to the above-described embodiments, the gateway 10 has been described, but is not limited thereto, and the gateway 10 may include at least some of the functions of a router or may be replaced by a router.

Meanwhile, FIG. 8 is a diagram illustrating a process of controlling facilities included in a building through a wired DDC according to various embodiments of the present invention.

The management server 100 of the building management system 1 may measure energy consumption (eg, water consumption, electricity consumption, heat consumption, etc.) for a plurality of areas in the building through a wireless mesh network (S801).

Specifically, a building may be divided into a plurality of zones (eg, first floor, second floor, conference room, lobby, etc.), and the management server 100 may measure energy consumption for each zone. For reference, the method of dividing the plurality of zones may vary, and may be divided according to each floor such as the first floor and the second floor, or may be divided according to divided places such as a meeting room and a lobby. In some cases, energy consumption for a plurality of buildings may be measured by dividing one building into one zone.

At this time, the same type of energy consumption may be measured for each of the plurality of zones (eg, water and electricity consumption measurement in the first zone, water and electricity consumption measurement in the second zone), and different energy consumption for each of the plurality of zones Energy usage can also be measured (e.g. electricity usage in a meeting room, gas usage in a lobby).

In addition, the management server 100 may remotely receive and update energy usage for a plurality of zones from a wireless DDC included in the wireless mesh network (S803).

Specifically, the plurality of zones include at least a first zone and a second zone, the plurality of wireless repeaters include at least first wireless repeaters and second wireless repeaters, and the plurality of measurement systems include at least first measurement systems and second measurement systems. It can be assumed to include

At this time, as shown in FIG. 1, the wireless DDC, the first wireless repeater, and the second wireless repeater form an upper mesh network, and the first wireless repeater and the first measurement system form a first lower mesh network. 2 wireless repeaters and a second measurement system may form a second lower-level mesh network.

For reference, in the present invention, the first lower-level mesh network may measure energy usage in a first zone, and the second lower-level mesh network may measure energy usage in a second zone.

Eventually, the wireless DDC obtains the energy usage for the first zone measured by the first measuring system from the first wireless repeater, transmits the data to the management server 100, and obtains the energy usage for the second zone measured by the second measuring system. can be obtained from the second wireless repeater and transmitted to the management server 100.

Meanwhile, the energy usage includes at least one of water usage, electric power usage, and gas usage, and includes the number of a plurality of first measurement systems included in the first lower-level mesh network and a plurality of second measurement systems included in the second lower-level mesh network. The number of measuring systems may be recorded in the database 130 in advance.

At this time, the processor 120 of the management server 100 includes a plurality of first energy usage data (from a plurality of first measurement systems) for the first area (eg, the first floor) acquired by the first wireless repeater through the wireless DDC. acquisition) is received, and it is possible to determine whether there is an abnormality in the first lower-level mesh network by comparing the number of first measuring systems and the number of first energy usage data recorded in the database 130 .

That is, the processor 120 compares the number of first energy usage data obtained from the plurality of first measurement systems with the number of first measurement systems recorded in the database 130, and compares the number of the plurality of first energy usage data. If is less than the number of recorded first measurement systems, the processor 120 of the management server 100 may determine that there is an error in the first lower-level mesh network.

In addition, the management server 100 may obtain information on each of a plurality of first measurement systems as well as the number of the first measurement systems from the first wireless repeater. For example, identified information such as gas usage measurement data on the first floor of a building and water usage measurement data on the first floor of a building may be obtained. At this time, the processor 120 of the management server 100 may determine that a problem related to the data has occurred when it is confirmed that specific data (eg, gas usage measurement data of the second floor of a building) has not been obtained.

That is, the processor 120 of the management server 100 determines whether an abnormality has occurred based on the number of first energy usage data obtained primarily, and if it is determined that there is an abnormality in the number in the first determination, Secondarily, it may be determined whether any specific data among a plurality of first energy usage data has not been acquired.

In this case, it may usually correspond to a communication problem or a problem of the measuring device itself, and the processor 120 of the management server 100 may transmit related information to the manager terminal 200.

Energy usage monitoring for the second zone may be performed in a similar manner. The processor 120 of the management server 100 receives a plurality of second energy usage data for a second zone (eg, the second floor) acquired by the second wireless repeater, and the first energy usage data recorded in the database 130 It is possible to determine whether there is an abnormality in the second lower-level mesh network by comparing the number of two measurement systems with the number of second energy usage data.

Although only the first and second zones have been described above, the same can be applied to other zones, and not multiple zones for one building such as the 1st and 2nd floors, but each other such as the 1st and 2nd buildings. For different buildings (one zone corresponds to one building), each sub-level mesh network may be applied.

In the case of the wireless mesh network of the present invention, a measurement system (eg, water meter) checks every predetermined time (eg, 15 minutes), and the measured usage data is transmitted to the management server 100 via a wireless repeater and a wireless DDC, That data can be cumulative. That is, the processor 120 may remotely receive energy usage for a plurality of zones from a wireless DDC included in the wireless mesh network every preset time (eg, 15 minutes), and update the energy usage information.

However, the preset time may be set differently for each period. For example, in seasons (eg, summer and winter) in which high energy consumption is expected, the measurement period of the energy consumption may be shortened, and accordingly, the preset time of the corresponding wireless mesh network may be reduced to 10 minutes. there is.

Conversely, in seasons when energy usage is expected to be low (eg, spring and autumn), the energy usage measurement period may be longer, and accordingly, the preset time of the corresponding wireless mesh network may be increased to 30 minutes.

In addition, according to an embodiment of the present invention, the building management system 1 may measure energy usage through a wireless mesh network, determine whether the energy usage is appropriate for each unit time (eg, 1 hour), Accordingly, a warning alarm may be provided to the manager terminal 200 . Of course, depending on the case, whether or not the energy usage is appropriate is also determined according to the measurement period of the energy usage (eg, 10 minutes, 15 minutes, 30 minutes, 1 hour, etc.), and a warning alarm is sent to the manager terminal 200. can also provide. That is, it is possible to measure the amount of energy used and to determine whether the amount used is appropriate.

According to an embodiment of the present invention, the processor 120 may determine whether the energy usage is appropriate based on the reference energy usage, and setting the reference energy usage will be described below.

Since each building has a different total floor area, location, ambient temperature, and number of people, the standard energy consumption is inevitably different from each other.

At this time, the processor 120 of the management server 100 determines based on the reference energy usage per unit area or the reference energy usage per person before a predetermined period (eg, 1 year) elapses from the time when the energy usage starts to be measured or managed. Based on the first reference energy usage, it may be determined whether the energy usage for all of the plurality of zones is appropriate.

Here, the information on the standard energy consumption per unit area and the standard energy consumption per number of persons may be obtained in advance, and the predetermined period is a period during which energy consumption-related data is accumulated and statistics can be calculated (eg, 1 year) ), which may vary from case to case.

For convenience of description, the total floor area of the building (the total area of the total floor area of each floor of the building) and the number of registered people in the building are recorded in the database 130, and the management server 100 uses standard energy consumption per unit area and standard energy per number of people. It can be assumed that information on usage has been acquired.

For reference, if a specific building has a total floor area of 5000 m ² and the standard energy consumption per unit area per hour is 0.00416 kWh/m ² , the 1-1 standard energy consumption of the specific building per hour may correspond to 20.8 kWh.

In addition, if the number of registered people in a specific building is 100 and the standard energy consumption per person per hour is 0.187 kWh/person, the 1-2 standard energy consumption of the specific building (100 people) per hour corresponds to 18.7 kWh. can

At this time, the processor 120 of the management server 100 receives the energy consumption of each zone measured through each of a plurality of measurement systems from the wireless DDC and updates it every preset time (eg, 10 minutes, 15 minutes, 1 hour, etc.) and energy consumption (eg, 20 kWh) for the entire plurality of zones (entire buildings) can be obtained as a result of accumulation for one hour.

Here, the energy consumption may correspond to a sum of at least one or more of various types of energy sources such as water and electricity.

In this state, the processor 120 of the management server 100, the total floor area of the building (eg, 5000m ² ) and the 1-1 standard energy consumption calculated through the standard energy consumption per unit area (eg, 20.8 kWh) than the A first process of comparing whether or not energy consumption (eg, 20 kWh) for all of the plurality of zones (all buildings) is large may be performed every hour.

In addition, the processor 120 calculates the number of registered people (eg, 100 people) and the standard energy consumption per person, and the 1-2 standard energy consumption (eg, 18.7 kWh) is higher than the entire plurality of zones (eg, the entire building). A second process of comparing whether or not the energy usage (eg, 20 kWh) is large may be performed every hour.

When it is determined in at least one of the first process and the second process that the energy usage for all of the plurality of zones is greater, the processor 120 may transmit a notification message to the manager terminal 200 . In the case of the above example, since the energy usage (eg, 20kWH) is smaller than the 1-1 standard energy usage (eg, 20.8 kWh) but larger than the 1-2 standard energy usage (eg, 18.7 KWh), the manager terminal 200 A notification message can be delivered to.

The processor 120 of the management server 100 may perform the first process or the second process every hour, and the energy usage for the entire plurality of zones every hour is the 1-1 reference energy usage or the 1-1 2 It is possible to determine whether the energy usage is appropriate while comparing whether or not the energy usage is greater than the reference energy usage, and accordingly, a notification message may be delivered to the manager terminal 200 .

In the above, it is determined whether the energy usage is appropriate for each hour, but unlike this, it is determined whether the energy usage is appropriate for each measurement period (eg, 10 minutes, 15 minutes, etc.) of the energy usage, and accordingly, the manager terminal 200 You can also send notification messages to .

9 is a diagram illustrating a comparison between a second reference energy usage amount and an energy usage amount according to an embodiment of the present invention.

After a predetermined period (eg, one year) has elapsed from the time when the energy usage starts to be measured or managed, the processor 120 determines the second reference energy usage based on the statistical values of the energy usage for the entire plurality of zones. Thus, it is possible to determine whether the energy consumption for the entire plurality of zones is appropriate.

First, the processor 120 adjusts the energy usage for all of the plurality of zones for the predetermined period (eg, 1 year) based on the first reference energy usage (eg, considering the total floor area, number of people, etc.), and accordingly, the predetermined It can be assumed that the energy consumption for all of the plurality of zones obtained during the period corresponds to an appropriate level.

Accordingly, the processor 120 may obtain statistical values for the energy usage (all of a plurality of zones) obtained during the predetermined period. The processor 120 may obtain an average value of energy usage for each hour on a daily basis, and obtain a second reference energy usage as shown in FIG. 9 while displaying this as an accumulated value. That is, the second reference energy usage may indicate an accumulated value of an appropriate level of energy usage for one day (00:00 to 24:00).

In a state where the second reference energy usage is set, the processor 120 may obtain the energy usage for all of the plurality of zones, express it as an accumulated value, and compare it with the second reference energy usage.

The processor 120 displays and compares the second reference energy usage and the energy usage (accumulation) for the entire plurality of zones, and compares the energy usage (accumulation) for each hour (in some cases, the energy usage measurement period) to the second reference energy usage. It can be judged whether it is less than the amount used.

Referring to FIG. 9 , since energy usage (accumulation) in the interval between 10:00 and 12:00 has a value greater than the second reference energy usage, the processor 120 notifies the manager terminal 200 at 11:00. Messages may be delivered to induce reduction of energy consumption.

In some cases, it is possible to determine whether the energy usage (accumulation) is less than the second standard energy usage for each energy usage measurement period (eg, 10 minutes, 15 minutes, etc.) instead of every hour. In this case, 10:00 to 12 In the section between :00, the processor 120 may deliver a notification message to the manager terminal 200 a plurality of times.

According to an embodiment of the present invention, the second reference energy usage may vary according to seasons. In summer and winter, energy consumption is inevitably higher than in spring and autumn due to temperature control. Accordingly, the processor 120 of the management server 100 may obtain statistical values for each of the energy usage (all of a plurality of zones) acquired for a predetermined period (eg, one year) by season.

Accordingly, it is possible to obtain different second reference energy usage for each season, and after a predetermined period (eg, 1 year) has elapsed from the time when the energy usage starts to be measured or managed, the processor 120 performs a second reference energy usage in the spring. 1 compares standard energy use and energy use (cumulative), compares standard 2-2 energy use and energy use (cumulative) in summer, and compares standard 2-3 energy use and energy use (cumulative) in autumn In winter, a notification message may be delivered to the manager terminal 200 according to the comparison between the 2-4 reference energy usage and the energy usage (accumulation).

According to an embodiment of the present invention, it is possible to obtain energy usage for each of a plurality of zones, and determine whether or not it is greater than an appropriate energy usage.

The processor 120 of the management server 100 sets different lower-level mesh networks for each of a plurality of zones, and each lower-level mesh network includes at least one different measurement system. Accordingly, the processor 120 may obtain energy usage for each of a plurality of zones (eg, 1st floor and 2nd floor), and also obtain appropriate energy usage for each zone (based on total floor area or the number of registered persons). may be

Eventually, the processor 120 of the management server 100 may compare the appropriate energy usage and energy usage for each of the plurality of zones, and a notification message (e.g., 1st floor message that the energy usage exceeds the standard usage) can be delivered.

Meanwhile, according to an embodiment of the present invention, the building management system 1 may measure the amount of renewable energy (eg, solar energy, geothermal energy, etc.) generated through another wireless mesh network, based on the amount of energy generated. Thus, it is possible to re-determine whether or not the above-described energy consumption in the building is appropriate. In this regard, it will be reviewed below together with FIG. 10 .

10 is a diagram showing a schematic configuration of a building management system including a wireless mesh network capable of measuring energy generation according to an embodiment of the present invention.

As can be seen in FIG. 10 , the building management system 1 of the present invention may further include a predetermined wireless mesh network for measuring energy generation in addition to the wireless mesh network for measuring energy usage in a plurality of zones.

The predetermined wireless mesh network may also be divided into an upper mesh network and a lower mesh network. The upper mesh network includes a predetermined wireless DDC and a predetermined wireless repeater, and the lower mesh network includes a predetermined wireless repeater and at least one predetermined wireless mesh network. A meter may be included. The predetermined measuring system may measure solar energy generation amount, geothermal energy generation amount, and the like, and the solar energy generation amount measurement system may be usually located on the roof of a building. The photovoltaic energy generation, geothermal energy generation, etc. may be helpful in constructing a zero-energy building, which is one of the objects of the present invention.

For reference, although only one predetermined wireless repeater is shown in FIG. 10, a plurality of predetermined wireless repeaters may be included in the building management system 1 according to conditions, and power generation in different buildings may be respectively measured.

As a result, a predetermined wireless DDC and a predetermined wireless repeater acquires energy generation (eg, solar energy generation, geothermal energy generation, etc.) measured for a predetermined period (eg, 1 day, 1 month, etc.) from a predetermined measurement system, and the management server (100) The processor 120 of ) may remotely acquire the amount of energy generation measured by the predetermined measurement system through a predetermined wireless repeater and a predetermined wireless DDC, and update it to the database 130.

Next, the processor 120 may calculate an average amount of energy generation (eg, an average amount of energy obtained for 1 hour) for a first preset period (eg, 1 hour) based on the accumulated energy generation amount. It can be used to determine whether the energy consumption in the building is appropriate.

First of all, from the time when energy consumption was started to be measured before a predetermined period (eg, one year) has elapsed, the following is considered.

The total energy consumption in the building during the first preset period (eg, 1 hour) is 20 kWh, the 1-1 standard energy consumption calculated through the standard energy consumption per unit area per hour is 20.8 kWh, and the standard energy consumption per person per hour In a state where the 1-2 standard energy consumption calculated through is 18.7 kWh, it can be assumed that the average energy generation amount for the first preset period (eg, 1 hour) is 2 kWh for convenience of description.

At this time, the processor 120 compares the 1-1 reference energy usage (20.8 kWh) with respect to the remaining predetermined energy usage (18 kWh) excluding the average energy generation (2 kWh) from the total energy usage (20 kWh) in the building. A second process for comparing with the first process or the 1-2 reference energy usage (18.7 kWh) may be performed.

When it is determined that the predetermined energy usage is greater than the proper energy usage in at least one of the first process and the second process, the processor 120 may transmit a notification message to the manager terminal 200 .

In the case of the above embodiment, since it is determined that the predetermined energy usage (18 kWh) is smaller than the 1-1 standard energy usage (20 kWh) and the 1-2 standard energy usage (20.8 kWh), the processor 120 is a manager terminal ( 200), there will be no need to deliver a separate warning notification message.

Next, when a predetermined period (eg, one year) has elapsed from the time when the energy consumption was started to be measured, a look is as follows.

11 is a diagram showing a state in which energy usage is compared with a second reference energy usage in consideration of an energy generation amount according to an embodiment of the present invention.

The processor 120 of the management server 100 may obtain an average energy generation amount for a second predetermined period (eg, 1 day) and may remove it from the original energy usage (accumulation). That is, the processor 120 may compare the remaining energy usage (predetermined energy usage) with the second reference energy usage except for the amount of energy that can be generated by itself in the building, and on the graph (see FIG. 11), the 2nd reference energy usage A predetermined amount of energy that has moved in the minus direction of the y-axis by an average amount of energy generation during a predetermined period (eg, 1 day) and the second reference energy amount can be compared.

When the energy generation amount was not considered (see FIG. 9), the notification message was delivered because the energy use amount (cumulative) between 10:00 and 12:00 was greater than the second standard energy use amount between 10:00 and 12:00, but when the energy generation amount was considered (see FIG. 11) ) has less predetermined energy usage (energy usage (cumulative) - average energy generation) than the second reference energy usage, so the notification message will not be delivered.

According to an embodiment of the present invention, the processor 120 may set the average energy generation amount differently to adjust the predetermined energy usage amount corresponding to the comparison target. The amount of solar energy generation may vary depending on the time period (eg, season, etc.), and accordingly, the processor 120 may calculate different average energy generation amounts for each period.

Specifically, the processor 120 classifies the amount of energy generation accumulated up to the previous year by time (eg, season), and sets a predetermined period (eg, 1 hour, 1 day, 1 hour) for each period (eg season). month) average energy generation can be calculated. Therefore, it is possible to calculate different average energy generation amounts for spring, summer, autumn, and winter.

As a result, the processor 120 of the management server 100 may calculate an average energy generation amount matching each season, calculate up to a predetermined energy amount based on this, and perform comparison with the reference energy amount. After all, it is possible to determine whether or not the energy consumption is appropriate in a customized way. That is, the building management system 1 of the present invention may correspond to a control system for managing energy in a building.

Meanwhile, the processor 120 of the management server 100 may transmit energy usage for a plurality of zones to the manager terminal 200, and when input is received from the manager terminal 200, the processor 120 included in the building through a wired DDC. Equipment can be controlled (S805). In addition to the facility control, control of power/lighting may also be performed through a wired DDC or LCP panel based on the input of the manager terminal 200.

12 is a diagram showing a signal connection structure between a wireless DDC and a measurement system through a wireless repeater according to an embodiment of the present invention.

13 is a diagram illustrating a method in which a command signal of a wireless DDC is transmitted to each measurement system according to an embodiment of the present invention.

As can be seen in FIGS. 12 and 13, the wireless repeater is signal-connected to each measurement system through the lower-level mesh network, and the first communication module receives the output measurement data, and the measurement data received through the first communication module is transmitted to the wireless DDC. It may include a second communication module that delivers to.

The first communication module operates as a BS (Base Station) that is signal-connected to each measurement system communication module through the lower-level mesh network, collects measurement (meter reading) data, and uploads it to the second communication module, and each measurement system communication module and 1 Form an N:1 mesh network between communication modules.

That is, it is a communication structure in which the first communication module of the wireless repeater serves as a BS to collect meter reading data of each measurement system communication module and transfers the collected meter reading data to the wireless DDC through the second communication module.

If you want to configure the system to collect measurement data from the wireless repeater for each group, the frequency and Group ID of the measurement system communication module in each group can be set differently together with the wireless repeater.

After setting, the 1st communication module of the wireless repeater performs the role of BS in group units to collect measurement data, and when the 2nd communication module of the wireless repeater receives it, it operates as an RS (Relay Station) of the upper mesh network and It can be forwarded to DDC.

Here, the measurement of the measuring system can be performed through the wireless mesh network without installing the wireless repeater as described above. However, if the transmission is not performed at one time and the number of transmissions increases through the wireless mesh network, the communication time may increase, causing the wireless DDC to collect data after a set time. If this phenomenon appears regularly, a remedy for this is required, and the wireless repeater can be a solution to this.

Embodiments according to the present invention described above may be implemented in the form of program instructions that can be executed through various computer components and recorded on a computer-readable recording medium. The computer readable recording medium may include program instructions, data files, data structures, etc. alone or in combination.
