Referring first to FIG. 1, FIG. 1 illustrates a configuration of a building energy management system according to the present invention.

The building energy management system includes at least one facility 400 and a central controller 150 communicating with the facility 400. The building energy management system includes an input unit 110, an output unit 120, a sensor unit 130 and a database 140. The building energy management system includes a web service module 310 and an individual controller 330 for individual control. . The building energy management system further includes a communication unit 200 that performs communication between the facility 400, the central controller 150, and the web service module 310.

The facility 400 is a power consumption device installed in a building, for example, an air conditioner, an air conditioner 410, a heating, ventilation and air conditioning (HVAC) Fans, boilers, and the like.

The central controller 150 communicates with one or more facilities 400 and centrally controls the operation of the facility 400. Specifically, the central controller 150 comprehensively considers the device data, the operation data, the environmental condition data, and the user data of the facility 400, And determines the optimum point to optimize the rate of increase of the drive.

Here, the device data includes information on the type of the facility 400, for example, the type of the device such as the multi-type air conditioner 410 and the illumination 420, the installation location of the facility 400, ) &Lt; / RTI > itself.

The operation data includes, for example, the operation state of the facility 400, the operation pattern of the facility 400 depending on the user, the facility location, or the area, and the operation history for a certain period of time.

The environmental condition data may include at least one of natural environmental condition data such as external weather data, sunshine temperature, temperature, humidity, and current time, and an anthropic environmental condition such as user reacquisition, space characteristics, user connection position, You can include all of your data. In addition, the user data may further include the current position of the user, the taste or preference of the user.

The optimum point may be changed within a predetermined range according to the external device of the central controller 150, for example, whether it is interlocked with the database 140, another system installed in the building, characteristics of the building, and user preference . In addition, the user may set a minimum saving standard of energy consumption for the facility 400 in advance.

The reduction rate of the energy consumption is optimized in consideration of the device data, the operation data, the environmental condition data, and the user data in a direction to further increase the energy saving. In addition, the rate of increase of the efficient driving is optimized in a direction to further increase the user satisfaction by comprehensively considering the device data, the operating data, the surrounding environment status data, and the user data. As described above, since the relationship between the reduction rate of the energy consumption and the rate of increase of the efficient driving is in inverse proportion to each other, the optimal point for optimizing the simultaneous optimization is determined to automatically control the facility 400. [

The optimum point may be changed according to the characteristics of the building. That is, it can be categorized as a case where the energy consumption of the facility 400 is emphasized depending on the building and a case where the efficiency of the facility 400 is increased (for example, the comfort due to the efficient operation of the air conditioner is emphasized). Examples of the former include a company, a factory, a university, and the latter examples include a hospital, a nursing home, a bank, and a performance hall. For example, in a company or a factory, which is a large-scale building, the optimum point may be changed in a direction that emphasizes the reduction of energy consumption, and a special environment such as a hospital, a nursing home The optimum point can be changed in a direction that more emphasizes an increase in efficient driving or a user-customized control.

The central controller 150 automatically controls the facility 400 to match the thus determined optimal point. As a result, efficient energy management of buildings is possible.

Referring to FIG. 1 again, the building energy management system may further include a terminal device 500 that communicates with the central controller 150 and provides user requests to the central controller. The central controller 150 may determine the optimum point by further considering the user request, and may automatically control the facility.

The terminal device 500 may be connected to the central controller through a wired / wireless communication method. The terminal device 500 can perform communication with the central controller 150 through a communication unit 200 described later. The terminal device 500 includes, for example, one or more of a computer, a smart television, a smart phone, and a cellular phone.

For example, when the terminal device is a smart phone, the smartphone user can input the location of the attendant and the user request in real time through the network service. As shown in an example in FIG. 7, the central controller 150 displays a pop-up window indicating the location of the occupant registered by the smartphone user, the user's request, and the like.

The network service includes at least one of a message, a bulletin board, an e-mail, a website, and a social network. For example, referring to FIG. 7, a terminal device can transmit content to a central controller through a message service, simply, a 'message'. The message service includes a Short Message Service (SMS), an Enhanced Messaging Service (EMS), and a Multimedia Messaging Service (MMS). The message service can transmit not only text but also simple media such as ring tones, images, animations, etc., which are more various media than text. The message service can be a combination of various media such as a single medium as well as a multi media. Referring to FIG. 7, a terminal device transmits a facebook, which is one of social network services (SNS), to a central controller. The social network service includes a cyber bulletin board service provided in an Internet cafe or the like, and is provided in the name of cyworld, myspace, facebook, twitter, and the like.

The central controller 150 informs the administrator in the form of a pop-up window, and the unprocessed items can be continuously displayed. In addition, when the manager clicks the network service, the central controller 150 can display the facilities related to the occupant's location on the screen, and display a control window for controlling the corresponding space on the screen.

As another example, the central controller 150 can provide the determined optimal point, control status of the facility, status, and the like to the terminal apparatus 500 through the network service. 8A to 8D are diagrams showing various types of information that the central controller 150 provides to the terminal apparatus 500. FIG. As shown in FIG. 8A, the central controller 150 can provide the terminal device 500 with a summary of environment and setting information such as indoor / outdoor temperature, comfort, automatic operation, and set energy saving intensity (FIG. 8A). In addition, the central controller 150 can send the instantaneous power consumption amount (FIG. 8B), the monthly saving amount (FIG. 8C), and the like to the terminal device 500. In addition, the central controller 150 can provide a cumulative daily usage amount such as cumulative power consumption per time period and power charges per load to the user (Fig. 8D).

9 is a diagram illustrating a form in which a terminal device and a central controller share information through a social networking service. Referring to FIG. 9, a manager who manages a smartphone and a manager who manages a central controller can transmit and receive information in real time . Accordingly, convenience of the user can be considered, not one-sided control of the central controller.

Referring to FIG. 1 again, the building energy management system may further include a monitoring device 600 installed in the building and monitoring the inside and outside of the building. Here, the monitoring apparatus 600 may be a surveillance camera, for example, a CCTV camera. The central controller 150 can further determine the optimum point by considering the monitoring data of the sensing apparatus, and can automatically control the facility.

At this time, as shown in FIG. 7, the central controller 150 can display the monitoring devices 600 connected thereto on the screen. The administrator will be able to know the use of equipment such as air conditioners, lights, etc. that are not scheduled. The central controller can display the scene screen input through the monitoring device. The screen of the central controller can simultaneously display the monitor items together with the control items for each space, that is, the air conditioner, the illumination, and the like.

In addition, when the terminal device and the monitoring device are interlocked with the central controller, and the user of the terminal device transmits the location of the occupant and the user's request to the central controller through the network service, It can be checked through the monitoring device installed at the location of the occupant. Accordingly, it is possible to detect energy consumption and excess energy consumed in the empty space by interlocking with the monitoring apparatus, and to save the energy and energy consumption.

Referring to FIG. 2, a detailed configuration of the central controller 150 is shown. 2, the central controller 150 includes a saving mode setting module 151 and an optimum point calculating module 153. [

The saving mode setting module 151 sets a minimum saving standard of energy consumption for the facility according to a user input or a preset reference. For example, a premium saving mode with a minimum energy saving standard of 3%, a normal saving mode with a minimum energy saving standard of 5%, and a minimum energy saving standard of 10% It is possible to implement any one of the economical saving modes. It is also possible to directly set the value of the minimum saving standard of energy consumption according to user input or predetermined criteria. Thus, the minimum saving standard of the energy consumption of the facility 400 can be set step by step through the saving mode setting module 151 so that the optimal environment can be set according to various environments.

The optimal point calculating module 153 numerically measures the expected reduction rate of the energy consumption and the expected increase rate of the efficient driving considering the device data, the running data, the surrounding environment state data, and the user data of the facility 400 in a comprehensive manner. The optimal point calculation module 153 calculates an optimum point for simultaneously optimizing the numerical estimated reduction rate and the expected rate of increase.

In this regard, FIG. 3 graphically shows the optimal points of the estimated saving rate and the estimated growth rate, which are quantified.

As shown, the x-axis of the graph represents the rate of increase in efficient driving of the facility, for example, the increase in comfort due to multi-climate control, and the y-axis of the graph represents the rate of energy savings. As described above, the 'optimal point' can be obtained by reflecting the various factors that are inversely related to the rate of efficient driving of the facility and the rate of energy consumption reduction, and can optimize both of them at the same time. According to the building energy management system of the present invention, it is possible to maximize the efficiency of the energy saving and the efficiency of the facility by taking the device data, the operation data, the surrounding environment state data, and the user data of the multi- have. That is, when the building energy management system according to the present invention is applied to the multi-type air conditioner 410, the rate of reduction of the energy consumption and the efficiency of the efficient driving of the facility are both adjusted to an optimum point do. The facility is automatically controlled according to such an optimum point. However, in the case where the energy saving rate is more important than the optimum point, the optimum point moves to the left along the curve of the graph, and in the special environment where the efficiency increase rate of the facility is more important, .

Referring again to FIG. 1, the database 140 is interlocked with the central controller 150 and stores device data, operation data, surrounding environment status data, and user data of the facility 400. In addition, the database 140 logicizes the control pattern for the facility 400 from the data. Also, the database 140 reflects the control data generated through the individual controller 330 on the control pattern and logicizes the control data.

The sensor unit 130 is installed in the building and senses the environmental condition data in real time. In an embodiment, the environmental condition data includes at least one of weather data, user reacquisition, spatial characteristics, user's connection location, current time, and external device interlocking. In addition, the sensor unit 130 may include an infrared sensor capable of detecting infrared rays, an action sensor for detecting movement of an object, a body reaction sensor for detecting a temperature of a person, a pulse or the like, A humidity sensor for sensing a change in humidity of the wind, a wind direction sensor for detecting the direction of wind, a light intensity sensor for sensing a change in illumination, and a timer sensor. The error occurrence rate can be lowered when the facility 400 is controlled through the combination of various sensors.

The input unit 110 receives the user data and / or receives monitoring and control commands for the facility 400.

The output unit 120 displays the current state of the central controller 150 and / or the operation result.

The communication unit 200 performs communication between the facility 400 and the central controller 150. In addition, the communication unit 200 performs communication between the facility 400 and the web service module 310. In addition, the communication unit 200 performs communication between the central controller 150 and the web service module 310. In an embodiment, the communication unit 200 is a white-net gateway. In this case, it can be connected using RS-485 communication cable.

The building energy management system according to the present invention further includes a web service module 310 and an individual controller 330 for individual control of the user to simultaneously satisfy the operational convenience of the actual user and the central manager of the facility 400 can do.

The web service module 310 is capable of communicating with the central controller 150 and one or more facilities 400. The web service module 310 provides the individual controller 330 with device data, operation data, environmental condition data, and user data of the facility 400 via the Internet. To this end, the web service module 310 includes a data extracting unit (not shown) for periodically receiving data stored in the database 140 through the communication unit 200, And a web server (not shown) that provides a protocol to provide the display information generated by the web page generator to the individual controller 330 via the Internet .

The individual controller 330 comprehensively considers the data provided from the web service module 310 and generates control data for individually controlling one or more facilities 400. In addition, the individual controller 330 provides the generated control data to the central controller 150 to control the facility 400.

Referring to FIG. 6, in another form of FIG. 1, the building energy management system according to another embodiment further comprises a cloud server 10 capable of freely interworking various information and functions in a building. At this time, the configuration of the building energy management system of FIG. 1 is connected through the network 20 instead of the communication unit. That is, the cloud server 10 can communicate with the facility 400, the central controller 150, and the terminal device 500 via the network 20, and can transmit, receive, and store the data. Further, in the case of a building energy management system in which the monitoring apparatus 600 is further installed, surveillance data can be further shared.

The information and data of the building energy management system can be provided to the user through the terminal device or the like by using the cloud server 10, and in particular, the manager can be provided through the terminal device 500 other than the central controller 150 The facilities of the building energy management system can be controlled.

The control method of the building energy management system according to the present invention described above will now be described. 4 is a flowchart illustrating a method of controlling a building energy management system according to an embodiment of the present invention.

First, device data, operation data, environmental condition data, and user data of the facility are collected (S10). The estimated reduction rate of the energy consumption and the estimated increase rate of the efficient operation for the facility are all calculated in consideration of the collected data (S20). An optimum point for optimizing the estimated reduction rate of the calculated energy consumption and the expected increase rate of the efficient driving is determined (S30).

Control data to be individually controlled is generated based on the provided data. The generated control data is reflected in the facility control and stored as a database for the control pattern.

5 is a flowchart illustrating another embodiment of a method for controlling a building energy management system according to the present invention. First, a minimum saving standard of energy consumption for a facility installed in a building is set according to a user input or preset reference (S5). Then, the device data, the operation data, the environmental condition data, and the user data of the facility are collected (S10). The expected increase rate of efficient driving to the facility is calculated by taking the collected data together (S20 '). An optimal point for optimizing the minimum saving standard of the set energy consumption and the calculated rate of efficient driving is determined (S30 '). The facility is automatically controlled so as to match the optimum point (S40). At this time, the device data, the operation data, the environmental condition data, and the user data may be logicized and stored in a database. The stored data may be automatically updated in real time. When the user tries to individually control the facility (S50), the device data, the running data, the surrounding condition data, and the user data stored in the database are provided to the respective controllers via the Internet, and the provided data The control data to be individually controlled is generated (S60). The generated control data is reflected in the facility control and stored in a database for the facility control pattern.

Referring again to FIG. 4 or 5, the control method of the building energy management system may further include a step (S11) of receiving a user request through a terminal device. The terminal device communicates with the central controller and provides user requests to the central controller. The central controller can determine the optimum point further considering the user's request, and can automatically control the facility.

For example, when the terminal device is a smart phone, the smartphone user can input the location of the attendant and the user request in real time through the network service. As shown in an example in FIG. 7, the central controller displays a pop-up window indicating the position of the occupant who is posted by the smartphone user, the user's request, and the like.

The central controller informs the administrator in the form of a pop-up window, and the unprocessed items can continue to be displayed. When the manager clicks the corresponding network service, the central controller can display the facilities related to the occupant's position on the screen and display a control window for controlling the corresponding space on the screen.

As shown in FIG. 8A, the central controller can provide a summary of environment and setting information such as indoor / outdoor temperature, comfort, automatic operation, and energy saving intensity set to the terminal device (FIG. 8A). In addition, the central controller can send the instantaneous power usage amount (Fig. 8B), the monthly saving amount (Fig. 8C), and the like to the terminal device. In addition, the central controller can provide a cumulative amount of daily use such as cumulative power consumption by time and power charges by load to the user (Fig. 8D).

Referring again to FIG. 4 or 5, the control method of the building energy management system may further include a step (S12) of receiving monitoring data from a monitoring apparatus installed in the building. Here, the monitoring apparatus may be a surveillance camera, for example, a CCTV camera. The central controller can further determine the optimal point by taking into consideration the monitoring data of the sensing apparatus, and can automatically control the facility.

At this time, as shown in FIG. 7, the central controller can display the monitoring devices connected thereto on the screen. The administrator will be able to know the use of equipment such as air conditioners, lights, etc. that are not scheduled. The central controller can display the scene screen input through the monitoring device. The screen of the central controller can simultaneously display the monitor items together with the control items for each space, that is, the air conditioner, the illumination, and the like.

For example, in the case where the multi-air conditioner 410 is installed in the classroom, in order to optimize the reduction of energy consumption and the increase of efficient driving to the facility, for example, the operation of the air conditioner 410 is started before the start of the steel time, The optimum point can be determined so that the operation of the air conditioner 410 can be terminated.

If the environment condition data and the user data do not coincide with each other, for example, if the lecture time table is inconsistent with the user reacquisition, The point should be determined. Thereby reducing the energy consumption for the facility 400 and increasing the efficient driving can be optimized at the same time. In addition, for efficient energy management, the facility 400 can be controlled by interlocking the security system and / or access system installed in the university.

The above-mentioned building energy management system and its control method are applied to a hospital as follows. In a hospital, a building energy management system according to the present invention can be applied for patient monitoring purposes. Referring to FIGS. 4 and 5, the user data further includes the patient's name, ongoing therapy, specificity, patient status, and the like. In addition, the sensor unit 130 further includes a body reaction sensor that can precisely monitor the state of the patient in real time. The data of the patient's pulse, blood pressure, body temperature, blood glucose, etc. obtained from the body reaction sensor are logically stored together with other data and stored in the database 140. In this way, the optimal point must be determined to individually control the indoor unit vanes of the facility 400, for example, VRF HVAC (Variable Refrigerant Flow Heating, Ventilation, Air Conditioning), reflecting the condition of the patient. That is, the VRF HVAC can be controlled in a temperature and / or humidity range where the body temperature, blood pressure, pulse, etc. of the patient can ideally be maintained while monitoring the patient's condition in real time through the body reaction sensor, can be changed. Furthermore, when the patient is discharged, it is possible to interlock the system through the mobile device so that the updated control pattern can be equally applied to the equipments installed at home.

The configuration of the building energy management system can freely link various information and functions in the building through the cloud server. That is, the cloud server can communicate with the facility, the central controller, and the terminal device via the network, and can send and receive data and store it. Further, in the case of a building energy management system in which a monitoring device is further installed, surveillance data can be further shared.

The information and data of the building energy management system can be provided to the user through the terminal device and the like, and in particular, the manager can control facilities of the building energy management system, can do.

As described above, the building energy management system and the control method thereof according to the embodiment of the present invention can be applied to various fields such as weather data, usage pattern, convenience of operation, characteristics of a building or a building area, Etc., to determine the optimum point that simultaneously satisfies the reduction of energy consumption and the increase of the efficient driving, and accordingly, the facility is controlled so that efficient energy management can be performed. In addition, data related to facilities can be provided to individual controllers through a web server, so that individual control of facilities can be realized, thereby enabling efficient energy management and customized facility control.
