Description

Technical Field

[0001] The present invention relates to cooling function control, and more particularly, to a control system capable of remotely controlling and automatically controlling the temperature of an air conditioner in a telecommunication building. Background Art

[0002] Telecom service providers are one of the largest groups of electricity users. Most of the electricity used by telecom service providers is used to operate base stations or telecom buildings to operate telecom networks such as LTE (Long Term Evolution) and 5G (Fifth Generation). Telecom buildings consist of server devices and multiple transmission devices that generate heat, as well as cooling devices for removing the generated heat, and operate 24 hours a day, 365 days a year.

[0003] The amount of heat generated by the heat generating devices in the telecommunication buildings varies according to the volume of communication business and usage. Therefore, local heating is prone to occur in a certain space of the telecommunication building, and the characteristics of the heating vary according to the time and date of the weekly pattern and the characteristics of the surrounding floating population. On the other hand, in the case of the fixed-speed air conditioner, which accounts for the largest proportion of the cooling system in the telecommunication building, the compressor can only be turned on / off according to the set temperature and is controlled based on the temperature sensor value of the air inlet inside the air conditioner. Therefore, it is difficult to achieve the purpose of reducing the overall heating by controlling the output of the air conditioner according to the temperature around the cooling device.

[0004] Meanwhile, high temperature of telecommunication building installations is a serious problem that may cause communication failures, so air conditioners use a lot of power to keep indoor temperatures low. In particular, since similar cooling operations are performed even in the case of night, weekends, and winter when heat generation is low, additional power consumption is generated due to overcooling.

[0005] As described above, the typical control method of air conditioners in telecommunication buildings is to compare the temperature sensor at the air conditioner inlet with the set temperature and send a compressor on / off signal, and the set temperature is manually changed by a person. Here, since the air temperature around the air conditioner is determined as the temperature of the entire space of the telecommunication building, it is difficult to control the cooling according to the temperature of the entire space, and there is a problem of being unable to cope with instantaneous and localized heating. In addition, the typical control of air conditioners in telecommunication buildings does not take into account external influences such as outdoor temperature, so there is a problem of excessive or insufficient cooling supply. In addition, since there is no dead zone condition for the indoor temperature of the telecommunication building, there is a problem that the compressor is repeatedly turned on and off when the indoor temperature of the telecommunication building is maintained close to the set point, resulting in a loss of starting current. Summary of the invention

[0006] Technical issues

[0007] Therefore, the present invention aims to provide a cooling function control method for a telecommunication building and a server device supporting the method, which achieves a stable cooling state of the entire space of the telecommunication building by dynamically responding to the heating of the telecommunication building where local and instantaneous heating occurs.

[0008] Furthermore, the present invention aims to provide a cooling function control method for a telecommunication building and a server device supporting the method, which improves power waste due to overcooling or unnecessary cooling supply of the telecommunication building by performing optimized cooling control using techniques such as prediction of indoor temperature changes based on air conditioning control and air conditioning operation time control by maintaining an appropriate dead zone.

[0048] The present invention provides an example of finding the optimal cooling temperature by measuring external communication traffic forecast data, outdoor temperature, etc. and applying it to a telecommunication building.

[0049] Hereinafter, the types and roles of components included in a system environment will be described, and these components can provide optimized alternating operation combination information of a refrigerator included in the cooling system of the present invention.

[0050] Figure 1 An example of a cooling system operating environment supporting cooling function control for a telecommunication building according to an embodiment of the present invention is shown.

[0051] Reference Figure 1 According to an embodiment of the present invention, a cooling system operating environment 10 may include at least one administrator terminal 100 (or an electronic device for an administrator), a network 51 (or at least one of a mobile communication network, an Internet network, an intranet network, and a wired cable), a cloud server 200 (or a server device, a cooling control server device), and a cooling system 300 arranged in a telecommunication building (or a facility, a base station, or a data center in which a cooling system is installed).

[0052] A telecommunication building may be a facility such as a base station, a data center, etc., which continuously generates heat for the operation of communication services and whose heat generation varies locally or instantaneously according to the amount of communication services, or a facility that requires continuous cooling management. In a telecommunication building, a plurality of transmission devices supporting the transmission and reception of communication services and a plurality of server devices capable of storing the transmitted and received communication services may be arranged in a specific space. In particular, the telecommunication building may include a cooling system 300, which includes a plurality of air conditioners (or cooling devices, cooling equipment) capable of reducing the heat generated by the transmission devices and the server devices. At least some of the transmission devices and the server devices may have different heat generation according to the amount of communication services, and may have locally different heat generation according to the area where the amount of communication services increases. For example, if the telecommunication building is designed to handle the amount of communication services in multiple areas, the transmission devices and the server devices are provided to receive and transmit the communication services in the corresponding areas, and depending on the amount of communication services generated in each area, the heat generation of the transmission devices and the server devices handling a specific area may increase compared to other areas.

[0053] The cooling system 300 can manage the temperature of the telecommunication building (or the facility provided with the cooling system 300) to be lower than a preset temperature. The cooling system 300 can include a plurality of refrigerators (or air conditioners) for continuous temperature management, and at least some of the plurality of refrigerators can be operated alternately or as a whole. In the cooling system 300, a temperature sensor can be arranged near each of the devices installed in connection with the communication service or the devices generating heat, or arranged on the surface of the device, or arranged in the device for temperature management of the telecommunication building, and the temperature change in each area can be monitored based on the temperature information collected by the arranged temperature sensor. The cooling system 300 can determine whether to operate at least some of the cooling devices and the degree of operation in consideration of the monitored temperature change. According to an embodiment, the cooling system 300 can check the outdoor temperature and control the indoor temperature in the telecommunication building according to the outdoor temperature.

[0054] The network 51 may support the formation of a communication channel between the cooling system 300 and the cloud server 200 and between the administrator terminal 100 and the cloud server 200. In this regard, the network 51 may include at least one communication network element. For example, the network 51 may include various cables supporting wired communication channels, base stations supporting wireless communication channels, wireless access points, address allocation devices for identifying each device, routers for sending and receiving data, MEC (mobile edge computing), etc. In the example, the network 51 may include a cable connecting the cooling system 300 and the cloud server 200 in a wired manner, or a wireless communication element connecting them wirelessly. In addition, the network 51 may include a wireless communication network (or a wireless mobile communication network) that wirelessly connects the administrator terminal 100 and the cloud server 200. The network 51 includes at least some of the various communication elements that can form a channel for communication between the cooling system 300 and the cloud server 200 or between the administrator terminal 100 and the cloud server 200, and is not limited by type, form or scheme. For example, the network 51 can send the outdoor temperature collected by the meteorological agency and the cooling-related information collected by the cooling system 300 to the cloud server 200, provide the cooling system control information generated by the cloud server 200 to the cooling system 300, and send the screen related to the cooling system control to the administrator terminal 100.

[0055] The cloud server 200 may form a communication channel with the cooling system 300 through the network 51, and receive cooling-related information collected by the cooling system 300. In addition, the cloud server 200 may collect the outdoor temperature of the telecommunication building in which the cooling system 300 is installed. In this regard, the cloud server 200 may collect location information from the cooling system 300, and may collect the outdoor temperature corresponding to the location from the meteorological agency server. Alternatively, a temperature sensor capable of detecting the outdoor temperature of the telecommunication building in which the cooling system 300 is installed may be deployed outside the telecommunication building, in which case the cloud server 200 may receive information about the outdoor temperature from the temperature sensor deployed outside the telecommunication building.

[0056] The cloud server 200 may collect information about the outdoor temperature and indoor temperature of the telecommunication building, and control whether to operate the cooling device and the cooling temperature according to the indoor temperature of the telecommunication building, so that the temperature of at least some spaces is lower than a predetermined temperature. In this regard, the cloud server 200 may collect cooling device state information and cooling device power information from a cooling device state sensor and a cooling device power meter provided in the cooling device. In this process, the cloud server 200 may control the operation of the cooling device by using a remote controller provided in the telecommunication building or the cooling system 300. The cloud server 200 may collect information about the operation of the cooling system 300 and the cooling control state of the telecommunication building, and provide the collected information to the administrator terminal 100. In this process, the cloud server 200 may provide the administrator terminal 100 with information related to the manual control of the cooling system 300, and provide the telecommunication building with cooling-related control information corresponding to the control of the administrator terminal 100.

[0057] The administrator terminal 100 may access the cloud server 200 through the network 51, and then receive and output various information provided by the cloud server 200. In an example, the administrator terminal 100 may be provided as a desktop PC or a portable communication device, and may access the cloud server 200 via an Internet network, a Wi-Fi network, a base station, etc. The administrator terminal 100 may receive and install an application related to the operation of the cooling system provided by the cloud server 200. Alternatively, the administrator terminal 100 may access the cloud server 200 by using a web browser, and then receive and output a cooling system operation page provided by the cloud server 200 via the web browser. The administrator terminal 100 may output information about the current cooling control state of the telecommunication building through the cooling system operation page, output a screen interface related to manual control of the cooling system 300 of the telecommunication building, and support manual control of the cooling system 300 according to the input of the administrator.

[0058] As described above, the cooling system operating environment 10 according to one embodiment of the present invention performs cooling control by setting sensors in multiple areas and taking into account the sensor information of the multiple areas and the outdoor temperature of the facility so that the temperature of the multiple areas is lower than the specified value, thereby being able to continuously manage the cooling of facilities such as telecommunication buildings where the local space heating value changes instantaneously. Thus, the cooling system operating environment 10 of the present invention stably supports the temperature control of the telecommunication building, thereby preventing the transmission device or server device required for the operation of the telecommunication building from being overheated, supporting the provision of stable communication services, and improving the over-operation of the cooling device to support the reduction of the overall power usage.

[0059] Figure 2 is a diagram showing an example of a cooling system configuration according to an embodiment of the present invention.

[0060] Reference Figure 2 , the cooling system 300 according to the embodiment of the present invention may include an outdoor temperature collector 320, a plurality of region-specific temperature sensors 330, a plurality of cooling devices 340, a data processing unit 350, and a communication circuit 310. In addition, a hub connecting the plurality of region-specific temperature sensors 330 may be further included. In another example, the data processing unit 350 may include a hub.

[0061] The outdoor temperature collector 320 may collect the outdoor temperature. The outdoor temperature collector 320 may access the weather agency server using the communication circuit 310 of the cooling system 300 and collect the outdoor temperature corresponding to its location. The outdoor temperature collector 320 may send the collected outdoor temperature to the data processing unit 350. However, if the cloud server 200 is designed to collect the outdoor temperature directly from the weather agency server, the outdoor temperature collector 320 may be omitted and not included in the cooling system 300.

[0062] A plurality of region-specific temperature sensors 330 may be arranged in predetermined regions, respectively. For example, among the plurality of region-specific temperature sensors 330, a first temperature sensor may be provided in a first control region, a second temperature sensor may be provided in a second control region, and an Nth temperature sensor may be provided in an Nth control region. Here, N may be a natural number. Temperature sensors 330 may be provided to correspond to the number of control regions. A plurality of temperature sensors 330 may be connected to a data processing unit 350 via a hub. A plurality of temperature sensors 330 may collect temperature information of corresponding control regions in a specified time period and send the collected temperature information to the data processing unit 350.

[0063] The plurality of cooling devices 340 may include an air conditioner for cooling and an air conditioner controller for controlling the air conditioner. The cooling device 340 may be arranged at a designated location of the telecommunication building, for example, in a plurality of quantities. In the example, the cooling device 340 may be arranged at the edge of the telecommunication building in a plurality of quantities. The air conditioner controller may include a separate controller for temperature control of each cooling device 340. For example, when there are three cooling devices 340, three separate controllers may also be provided. The separate controller may control the operation of the air conditioner using infrared rays, like a general remote controller. For example, the air conditioner controller may also include a remote controller. The remote controller may be a device for controlling the separate controller. Therefore, the separate controller may be connected to the cloud server 200 or the administrator terminal 100 via remote control communication, and the administrator terminal is installed in the management office where the administrator who manages the telecommunication building works.

[0064] Each of the plurality of cooling devices 340 may include, for example, an air conditioning state sensor 341 and an air conditioning power meter 342. The air conditioning state sensor 341 may collect information on the on / off of the cooling device 340, the temperature setting information of the cooling device 340, whether the cooling device 340 is damaged, etc., and may transmit the collected information to the data processing unit 350. The air conditioning power meter 342 may measure the amount of power consumed by the cooling device 340, and transmit the measured power amount information to the data processing unit 350. In addition, although it is described above that the air conditioning state sensor 341 and the air conditioning power meter 342 are provided in each cooling device 340, one sensor and power meter may be provided to collect the state information and power amount of the plurality of cooling devices 340.

[0065] The data processing unit 350 may collect temperature information of each control area from the plurality of temperature sensors 330 at a specified period or in real time, and transmit the collected temperature information to the cloud server 200 via the communication circuit 310. In addition, the data processing unit 350 may collect operation information of the cooling device 340 (e.g., air conditioning state sensor information collected by the air conditioning state sensor 341 and air conditioning power consumption information collected by the air conditioning power meter 342) at a specified period or in real time, and transmit the collected information to the cloud server 200 via the communication circuit 310. For example, the data processing unit 350 may receive cooling system control information for controlling the cooling device 340 via the communication circuit 310, and transmit the received cooling system control information to a separate controller for controlling each cooling device 340 or a remote controller for managing the separate controller. Here, at least some of the remote controller and the separate controller may be provided as part of the data processing unit 350.

[0066] The communication circuit 310 may form a communication channel between the cloud server 200 and the data processing unit 350. Alternatively, the communication circuit 310 may support a communication connection of a hub included in the data processing unit 350 or a hub provided independently of the data processing unit 350. According to an example, the communication circuit 310 may include a modem (e.g., LTE CatM1, RS232) for the communication connection.

[0067] Figure 3 is a diagram showing an example of a telecommunication building to which a cooling system according to one embodiment of the present invention is applied.

[0068] Reference Figure 2 and Figure 3 According to the embodiment, the first type of telecommunication building 301 may include a plurality of electronic devices 300a for sending and receiving communication services, a plurality of temperature sensors 330, a plurality of cooling devices 340a, 340b and 340c, and an isolation facility 301a surrounding the above components. Here, the above cooling system may include, for example, a plurality of temperature sensors 330 and a plurality of cooling devices 340a, 340b and 340c, and Figure 3 Telecommunications buildings in the building may also include those related to the operation of the cooling system Figure 2 The data processing unit and communication circuit described in.

[0069] The plurality of electronic devices 300a may include a transmitting device and a server device for transmitting and receiving communication traffic. The plurality of electronic devices 300a may vary in at least some aspects of the number, size and shape of the transmitting device and the server device according to the amount of communication traffic to be handled by the first type telecommunication building 301.

[0070] The plurality of temperature sensors 330 may be evenly distributed in an area where the plurality of electronic devices 300a are arranged. Specifically, the plurality of temperature sensors 330 may be arranged at predetermined intervals in an area where the plurality of electronic devices 300a are arranged. The plurality of temperature sensors 330 may collect temperature information at a specified location and transmit the collected temperature information to the above Figure 2 The data processing unit 350 (or hub) described in .

[0071] The plurality of cooling devices 340a, 340b, and 340c may be, for example, evenly arranged at specific locations within the isolation facility 301a. For example, the plurality of cooling devices 340a, 340b, and 340c may include a first cooling device 340a disposed on the north side of the isolation facility 301a, a second cooling device 340b disposed on the south side of the isolation facility 301a, and a third cooling device 340c disposed on the entrance side of the isolation facility 301a. Meanwhile, although the first to third cooling devices 340a to 340c are exemplified for describing the first type of telecommunications building 301, the number, size, and shape of cooling devices that may be disposed in the telecommunications building may vary according to the administrator's policy. The plurality of cooling devices 340a, 340b, and 340c may be arranged in response to the above Figure 2 Alternatively, the first type telecommunication building 301 may further include a separate controller for driving the plurality of cooling devices 340a, 340b, and 340c, and the separate controller may perform on / off and temperature control of the corresponding cooling devices 340a, 340b, and 340c in response to the cooling system control information sent from the data processing unit 350.

[0072] The isolation facility 301a is a structure surrounding a plurality of electronic devices 300a, a plurality of temperature sensors 330, and a plurality of cooling devices 340a, 340b, and 340c, and may have a closed structure for efficient cooling operation. However, the isolation facility 301a may further include a ventilation channel for ventilation with the outside to allow external air circulation. The shape, size, and structure of the isolation facility 301a may vary according to the size and arrangement of the plurality of electronic devices 300a.

[0073] Figure 4 is a diagram showing another example of a telecommunication building to which a cooling system according to one embodiment of the present invention is applied.

[0074] Reference Figure 2 and Figure 4The second type telecommunication building 302 according to the embodiment may include a plurality of server racks 390a, 390b, and 390c on which electronic devices for sending and receiving communication services are placed (or electronic devices placed on the server racks), a plurality of temperature sensors 330, a plurality of cooling devices 340a, 340b, 340c, 340d, 340e, and 340f, an isolation facility 302a surrounding the above components, a separate controller 311 for controlling the plurality of cooling devices 340a, 340b, 340c, 340d, 340e, and 340f, and a remote controller 312. Here, the cooling system deployed in the telecommunication building may include a plurality of temperature sensors 330, a plurality of cooling devices 340a, 340b, 340c, 340d, 340e, and 340f, a separate controller 311, and a remote controller 312, and may also include Figure 2 A data processing unit and communication circuit are described in relation to the operation of the cooling system.

[0075] The isolation facility 302a may be provided in various structures in which a plurality of server racks 390a, 390b, and 390c, a plurality of temperature sensors 330, and a plurality of cooling devices 340a, 340b, 340c, 340d, 340e, and 340f may be placed. Although the shape of the isolation facility 302a is illustrated as a rectangular space in the horizontal direction in the figure, it is not limited thereto. For example, the isolation facility 302a may include: a polygonal or elliptical (or circular) side wall that encloses a specific space depending on the arrangement or size of the components arranged therein to ensure smooth flow of cooling air for cooling; and a structure that encloses the top and bottom of the side wall.

[0076] A plurality of server racks 390a, 390b, and 390c on which a plurality of electronic devices are placed may include, for example, a first server rack 390a on which a first electronic device is placed, a second server rack 390b on which a second electronic device is placed, and a third server rack 390c on which a third electronic device is placed. The server racks 390a, 390b, and 390c may vary according to the shape or size of the placed electronic devices. For example, when the electronic device has a structure formed longer in the horizontal direction, the server racks 390a, 390b, and 390c may also be formed longer in the horizontal direction corresponding to the shape of the electronic device. A plurality of server racks 390a, 390b, and 390c may, for example, be arranged at the center of the isolation facility 302a, or may be spaced apart from the sidewalls of the isolation facility 302a in the inward direction by a certain interval. In addition, the server racks 390a, 390b, and 390c may be spaced apart from each other. In the example, the spacing distance between the first server rack 390a and the second server rack 390b and the spacing distance between the second server rack 390b and the third server rack 390c can be formed to be the same. However, such spacing distances or arrangement positions of the server racks 390a, 390b, and 390c may be changed according to the administrator's policy for cooling system operation. Alternatively, the number, size, and position of the server racks 390a, 390b, and 390c may be changed according to the amount of communication traffic to be handled by the second type telecommunication building 302.

[0077] A plurality of temperature sensors 330 may be evenly distributed in server racks 390a, 390b, and 390c in which a plurality of electronic devices are placed, respectively. For example, some of the plurality of temperature sensors 330 may be arranged at a plurality of points of the first server rack 390a, similarly, some of the other sensors may be arranged at a plurality of points of the second server rack 390b, and the remaining sensors may be arranged at a plurality of points of the third server rack 390c. Although it is shown in the figure that three temperature sensors 330 are arranged in each of the server racks 390a, 390b, and 390c, the present invention is not limited thereto. For example, a greater number of temperature sensors may be placed, or a smaller number of temperature sensors may be placed, depending on the size of the server racks 390a, 390b, and 390c or the heat generated by the electronic devices. A plurality of temperature sensors 330 may collect temperature information and send the collected temperature information to the data processing unit 350.

[0078] A plurality of cooling devices 340a, 340b, 340c, 340d, 340e, and 340f may be, for example, uniformly arranged at specific locations within the isolation facility 302a. For example, each of the plurality of cooling devices 340a, 340b, 340c, 340d, 340e, and 340f may be arranged at an edge of the isolation facility 302a. In an example, based on the illustrated drawings, the plurality of cooling devices 340a, 340b, 340c, 340d, 340e, and 340f may include: a first cooling device 340a, a second cooling device 340b, and a third cooling device 340c, which are arranged on the left side wall of the isolation facility 302a so as to blow cooling air toward the center of the isolation facility 302a; a fourth cooling device 340d, a fifth cooling device 340e, and a sixth cooling device 340f, which are arranged on the right side wall of the isolation facility 302a so as to blow cooling air toward the center of the isolation facility. A plurality of cooling devices 340a, 340b, 340c, 340d, 340e, and 340f may be arranged to be spaced apart from one another. In an example, a plurality of cooling devices 340a, 340b, 340c, 340d, 340e, and 340f may be arranged to blow cooling air into the space between the server racks 390a, 390b, and 390c. For example, the first cooling device 340a and the fourth cooling device 340d may be arranged to blow cooling air into the space between the north side wall of the isolation facility 302a and the first server rack 390a. The second cooling device 340b and the fifth cooling device 340e may be arranged to blow cooling air into the space between the first server rack 390a and the second server rack 390b in the isolation facility 302a. The third cooling device 340c and the sixth cooling device 340f can be arranged to blow cooling air into the space between the second server rack 390b and the third server rack 390c in the isolation facility 302a. According to the example, the space between the first server rack 390a and the second server rack 390b located in front of the second cooling device 340b can be defined as the control area of ​​the second cooling device 340b. Similarly, each of the cooling devices 340a, 340b, 340c, 340d, 340e and 340f blows cooling air into a specific space that can be set as the control area of ​​the corresponding cooling device. Each of the cooling devices 340a, 340b, 340c, 340d, 340e, and 340f manages the temperature values ​​of the server racks 390a, 390b, and 390c in the control area. At this time, the adjacent cooling devices may affect the temperature of the control area. For example, the second cooling device 340b and the third cooling device 340c can affect the temperature of the control area shown.

[0079] The individual controller 311 may be arranged adjacent to or electrically connected to the plurality of cooling devices 340a, 340b, 340c, 340d, 340e, and 340f so as to individually control each of the plurality of cooling devices 340a, 340b, 340c, 340d, 340e, and 340f. The individual controller 311 may be arranged to correspond to the number of the plurality of cooling devices 340a, 340b, 340c, 340d, 340e, and 340f.

[0080] The remote controller 312 may be included in a hub or a data processing unit, or may be provided to perform the role of a hub or a data processing unit. The remote controller 312 may collect temperature information from the temperature sensor 330, send it to the cloud server 200, and receive cooling system control information from the cloud server 200 or the administrator terminal 100. The remote controller 312 may generate a control signal for controlling the separate controller 311 based on the received cooling system control information, and send the generated control signal to the separate controller 311. In response to the control signal received from the remote controller 312, the separate controller 311 may perform on / off control of the cooling devices 340a, 340b, 340c, 340d, 340e, and 340f and temperature control for cooling air.

[0081] According to an embodiment, the remote controller 312 may send information received from the temperature sensor 330 to the cloud server 200, and the remote controller 312 may receive cooling system control information requesting temperature adjustment (e.g., reduction of 2 degrees) of the control area managed by the second cooling device 340b from the cloud server 200. The remote controller 312 may generate a control signal for temperature adjustment of the second cooling device 340b by checking the received cooling system control information, and then send the control signal to a separate controller for controlling the second cooling device 340b to reduce the temperature of the control area of ​​the second cooling device 340b. In another example, the remote controller 312 may directly form a communication channel with the administrator terminal 100. The remote controller 312 may receive the cooling system control information provided by the administrator terminal 100, and control the cooling on / off or cooling level of the cooling devices 340a, 340b, 340c, 340d, 340e, and 340f in response to the received cooling system control information. Meanwhile, although it is described above that the remote controller 312 transmits the temperature information of the temperature sensor 330 to the cloud server 200 , the remote controller 312 may directly transmit the collected temperature information to the administrator terminal 100 .

[0082] Figure 5 is a diagram showing an example of a device configuration of a cloud server according to an embodiment of the present invention.

[0083] Reference Figures 1 to 5 The cloud server 200 (or control server device) of the present invention may include a server communication circuit 210 , a server memory 230 , and a server processor 250 .

[0084] The server communication circuit 210 (or server communication interface) may support the formation of a communication channel with the cooling system 300 and the administrator terminal 100. In this regard, the server communication circuit 210 may include a first communication circuit 211 for forming a communication channel with the cooling system 300 and a second communication circuit 212 for forming a communication channel with the administrator terminal 100. The first communication circuit 211 and the second communication circuit 212 are not limited to a specific communication scheme, communication type, or communication module type. The first communication circuit 211 and the second communication circuit 212 may be communication circuits of the same type or operating in the same scheme, or may be different communication circuits. In the server communication circuit 210, the first communication circuit 211 may receive cooling related information from the cooling system 300, and provide cooling system control information to the cooling system 300 under the control of the server processor 250. In the server communication circuit 210, the second communication circuit 212 may provide the administrator terminal 100 with operation information or cooling system control information of the cooling system 300, and receive control information about manual control of the cooling system 300 from the administrator terminal 100.

[0085] The server memory 220 may store at least one program and data required for the operation of the cloud server 200. For example, the server memory 220 may cumulatively store cooling system operation information provided according to the operation of the cooling system 300. In addition, the server memory 230 may store information about the communication traffic in the telecommunication building for each electronic device or server rack. The server memory 230 may store information about the heat generated according to the communication traffic.

[0086] The server processor 250 may receive cooling related information (e.g., temperature information collected by a temperature sensor, cooling devices (e.g., Figure 4 The server processor 250 may include a data collector 251, an optimal cooling load calculator 252, an air conditioning controller 253, and an information provider 254.

[0087] The data collector 251 may collect cooling related information related to the operation of the cooling system 300 at a predetermined time point or in response to a request from an administrator or a request from the administrator terminal 100. For example, the cooling related information may include the amount of communication traffic processed at the telecommunications building, temperature information collected by the temperature sensor 330, and the cooling device ( Figure 3 340a to 340c or Figure 4 340a to 340f in, hereinafter referred to as 340). According to an example, the data collector 251 can collect cooling related information at specified time intervals. Alternatively, if the communication traffic increases to above a specified reference value when the data collector 251 collects information about the communication traffic, the data collector 251 can collect the remaining information of the cooling related information, such as the temperature information and status information of the cooling device 340. Alternatively, the data collector 251 can only preferentially collect information about the communication traffic, provide cooling system control information to the cooling system 300, and then collect temperature information from the temperature sensor 330. The data collector 251 can collect outdoor temperature values ​​from the cooling system 300, or access a meteorological agency server to collect outdoor temperature.

[0088] The optimal cooling load calculator 252 may generate cooling system control information for temperature control of the cooling system 300 based on the cooling related information collected by the data collector 251. For example, the optimal cooling load calculator 252 may use the predicted value to prevent overheating and overcooling of the cooling device 340. For example, the optimal cooling load calculator 252 may calculate the predicted outdoor temperature at a specific time point in the future (e.g., 1 hour later) before the control time point of the cooling device 340 and the predicted traffic volume in the control area managed by the cooling device 340. The predicted traffic volume may include a value obtained by learning using the communication traffic volume collected so far and the past traffic volume under the same or similar conditions (e.g., conditions at the same or similar time points when various events occur).

[0089] The optimal cooling load calculator 252 can specify the electronic device that will overheat based on the predicted outdoor temperature and the predicted traffic volume at the control time point, identify the control area where the electronic device is set, and then generate cooling system control information, which includes the set temperature value of the minimum power required by the cooling device responsible for the control area to prevent the electronic device from overheating. Here, the optimal cooling load calculator 252 can set the set temperature lower as the predicted outdoor temperature is higher and as the predicted traffic volume is larger. In another example, the optimal cooling load calculator 252 can identify the predicted outdoor temperature (or actual outdoor temperature) and the set temperature, and create cooling system control information to use the outdoor temperature when the predicted outdoor temperature (or actual outdoor temperature) is lower than the set temperature. If the predicted traffic volume is less than the specified value, the optimal cooling load calculator 252 can generate cooling system control information to maintain the current state.

[0090] When the cooling system 300 drives at least some of the cooling devices 340 according to the set temperature included in the cooling system control information transmitted from the cloud server 200, the data collector 251 may collect temperature information of each area (or control area) from the temperature sensor 330 of the cooling system 300. If there is no overheated or overcooled electronic device as a result of analyzing the collected temperature information, the optimal cooling load calculator 252 may determine that the cooling device 340 is operating at an appropriate set temperature, thereby controlling the cooling device 340 to maintain the operating state.

[0091] If there is an overheated electronic device among the electronic devices, the optimal cooling load calculator 252 may additionally adjust the set temperature of the cooling device in the control area where the overheated electronic device is located. Figure 4If the electronic device in the control area in the direction in which the cooling air of the above-mentioned second cooling device 340b is blown out is overheated, the optimal cooling load calculator 252 can generate cooling system control information, which reduces the set temperature of at least one of the fourth cooling device 340d or the third cooling device 340c adjacent to the second cooling device 340b. For example, the optimal cooling load calculator 252 can determine whether the set temperature of the fourth cooling device 340d (or the third cooling device 340c) can be further reduced, and if it is determined that the set temperature of the fourth cooling device 340d (or the third cooling device 340c) cannot be changed, the cooling system control information can be generated to further reduce the set temperature of the second cooling device 340b. For example, the optimal cooling load calculator 252 can compare the current set temperature of the fourth cooling device 340d with the current set temperature of the second cooling device 340b, and if the current set temperature of the fourth cooling device 340d is lower than the current set temperature of the second cooling device 340b, the set temperature of the second cooling device 340b can be controlled to be further reduced. Alternatively, if the current set temperature of the fourth cooling device 340d reaches a predetermined lower limit threshold, the optimal cooling load calculator 252 can control the set temperature of the second cooling device 340b (or the third cooling device 340c) to decrease without further changing the set temperature of the fourth cooling device 340d. Here, the lower limit threshold can be defined as the limit temperature that can reduce the temperature of the cooling device.

[0092] In another example, the optimal cooling load calculator 252 may determine that the set temperature of the fourth cooling device 340d may be changed, and check whether the set temperature of the second cooling device 340b is higher than the set temperature of the fourth cooling device 340d. If the set temperature of the second cooling device 340b is determined to be higher than the set temperature of the fourth cooling device 340d, the optimal cooling load calculator 252 may control the set temperature of the second cooling device 340b to be lowered in terms of energy efficiency. If the set temperature of the second cooling device 340b is determined to be lower than the set temperature of the fourth cooling device 340d, the optimal cooling load calculator 252 may control the set temperature of the fourth cooling device 340d to be lowered in terms of energy efficiency.

[0093] In another example, if there is an overcooled electronic device among the electronic devices in the control area of ​​the second cooling device 340b, the optimal cooling load calculator 252 can determine whether the set temperature of the adjacent cooling device (e.g., the first cooling device 340a (or the third cooling device 340c)) of the second cooling device 340b can be increased. If it is determined that the set temperature of the first cooling device 340a cannot be changed (e.g., if the set temperature of the first cooling device 340a reaches a predetermined upper limit threshold), the optimal cooling load calculator 252 can control the set temperature of the second cooling device 340b to be lowered. Here, the upper limit threshold can be defined as an upper limit temperature value to which the temperature of the cooling device can rise. If it is determined that the set temperature of the first cooling device 340a can be changed, the optimal cooling load calculator 252 can also control the set temperature of the first cooling device 340a to be lowered.

[0094] If temperature information of a preset threshold or higher is collected within a predetermined time period during the process of detecting whether the electronic device is overcooled or overheated, the optimal cooling load calculator 252 can control the set temperature adjustment of the cooling device. The predetermined time period can be, for example, several minutes. In this process, the optimal cooling load calculator 252 can monitor the temperature change by repeatedly collecting temperature information at a preset number of times within a predetermined time period. Through this control, the optimal cooling load calculator 252 can prevent the temperature adjustment from occurring too frequently.

[0095] The air conditioning controller 253 may transmit the cooling system control information transmitted by the optimal cooling load calculator 252 to the cooling system 300 of the telecommunication building through the server communication circuit 210. In this regard, the air conditioning controller 253 may form a communication channel with the cooling system 300 and transmit the cooling system control information to the cooling system 300 through the communication channel. In addition, when the air conditioning controller 253 may receive a control signal related to the control of the cooling system 300 of the administrator terminal 100 from the information provider 254, the air conditioning controller 253 may transmit the received control signal to the cooling system 300.

[0096] The information provider 254 may generate information related to the operation of the cooling system 300 and provide the generated cooling system operation information to the administrator terminal 100. In this process, the information provider 254 may create a screen corresponding to the cooling system operation information and provide the screen to the administrator terminal 100. In addition, when the information provider 254 may receive a control signal related to the control of the cooling system 300 from the administrator terminal 100, the control signal is sent to the air conditioning controller 253.

[0097] Figure 6 is a diagram showing another example of an operating environment of a cooling system according to an embodiment of the present invention.

[0098] Reference Figure 6 The cooling system operating environment 11 according to the embodiment may include a cloud server 201 and a third type telecommunication building 303. In addition, the cooling system operating environment 11 may further include a meteorological agency server 400.

[0099] The third type telecommunication building 303 may include a plurality of temperature sensors 330, a plurality of cooling devices 340, a temperature data hub 361, a monitoring system 363, and an air conditioning automatic control system 365. Here, the cooling system of the third type telecommunication building 303 may include, for example, at least some of the plurality of temperature sensors 330, the plurality of cooling devices 340, the monitoring system 363, the temperature data hub 361, and the air conditioning automatic control system 365.

[0100] The plurality of temperature sensors 330 may be respectively arranged at designated locations of the third type telecommunication building 303. In an example, the plurality of temperature sensors 330 may be arranged to collect temperature information of various locations of electronic devices arranged in the first type telecommunication building 301. Alternatively, the plurality of temperature sensors 330 may be arranged at least one by one in each control area of ​​the plurality of cooling devices 340, which are arranged to reduce the heating of the electronic devices. The plurality of temperature sensors 330 may collect temperature information at a designated period or in real time, and transmit the collected temperature information to the temperature data hub 361.

[0101] The plurality of cooling devices 340 may be disposed at various locations of the third type telecommunication building 303. Alternatively, the plurality of cooling devices 340 may be arranged to be spaced at predetermined regular intervals and to discharge cooling air based on a control area where electronic devices are placed in the third type telecommunication building 303. In an example, as described above, the plurality of cooling devices 340 may be arranged to discharge cooling air from the edge of the isolation facility toward the center.

[0102] The temperature data hub 361 can collect temperature information of the plurality of temperature sensors 330 and send it to the cloud server 201. The temperature data hub 361 can be, for example Figure 2 At least a portion of the data processing unit 350 described in .

[0103] The monitoring system 363 may detect the communication traffic sent and received through the third type telecommunication building 303, and transmit the detected communication traffic to the cloud server 201. In an example, if the communication traffic of the electronic devices of the third type telecommunication building 303 exceeds a predefined value and lasts for a specified time period, the monitoring system 363 may transmit information about the detected communication traffic to the cloud server 201.

[0104] The air conditioning automatic control system 365 can receive cooling system control information (or air conditioning control information) from the cloud server 201, and provide at least a portion of the received cooling system control information to multiple cooling devices 340. In this process, the air conditioning automatic control system 365 can check the cooling system control information to identify the cooling device that needs temperature adjustment, and send a control signal to at least one cooling device. In the example, the air conditioning automatic control system 365 can generate and send a control signal for controlling one or more cooling devices to adjust the heating state or overcooling state of the electronic device placed in a specific area. The air conditioning automatic control system 365 can also be configured to include at least one of the remote controller and a separate controller or a data collector and a communication circuit, for example, as described above.

[0105] The cloud server 201 may operate as an AI-based cooling optimization server. The cloud server 201 may include, for example, an optimal cooling load calculator 252, a data collector 251 (collecting building temperature / communication traffic / outdoor air data), an air conditioning controller 253 (or AI mode), and an information provider 254 (or manual mode / RM). The cloud server 201 may collect outdoor air data from the meteorological agency server 400, and generate cooling system control information for controlling the cooling system 300 based on the collected outdoor air data and the predicted communication traffic received from the third type telecommunication building 303. The cloud server 201 may perform the same operations as above in Figure 5 The operations correspond to the operations of the server processor 250 of the cloud server 200 described in .

[0106] Figure 7 is a diagram showing still another example of the operating environment of the cooling system according to the embodiment of the present invention.

[0107] Reference Figure 7 , the cooling system operating environment 12 according to the embodiment may include a cloud server 200 (or an optimal control server) and a fourth type telecommunication building 304 .

[0108] The cloud server 200 may have the same Figure 5 or Figure 6The cloud server 200 may have the same or similar configuration as described in . For example, the cloud server 200 may collect outdoor air data from a weather agency server, and collect business data from the fourth type of telecommunication building 304. The cloud server 200 may calculate a predicted outdoor temperature and a predicted communication traffic volume by learning based on the collected outdoor air data and business data, and in response to the calculated predicted outdoor air temperature and predicted communication traffic volume, may correspondingly calculate a heating temperature to be generated in an electronic device, an expected temperature of the fourth type of telecommunication building 304 according to the heating temperature, and a set temperature of at least one cooling device. The cloud server 200 may send cooling system control information including the calculated set temperature value to the cooling system of the fourth type of telecommunication building 304.

[0109] The fourth type telecommunication building 304 may include, for example, a first old type cooling device 340a, a second old type cooling device 340b, a third old type cooling device 340c, a fourth new type cooling device 340_1, and a fifth new type cooling device 340_2. In addition, the fourth type telecommunication building 304 may include first individual controllers 311a to 311c wired to the first old type cooling device 340a to the third old type cooling device 340c, a remote monitoring system (RMS) 363 for controlling the fourth new type cooling device 340_1 and the fifth new type cooling device 340_2, a communication hub 361 for sending control signals to the first individual controllers 311a to the third individual controllers 311c, and a communication circuit 310 connected to the communication hub 361. The communication hub 361 may be wirelessly connected to the first individual controllers 311a to the third individual controllers 311c. The communication hub 361 may be connected to a plurality of temperature sensors 330. The plurality of temperature sensors 330 may be wirelessly connected to a communication hub 361. The communication hub 361 may have, for example, the same Figure 6 The communication hub 361 may be wired to the communication circuit 310 in RS232 mode. Alternatively, the communication hub 361 may be wirelessly connected to the communication circuit 310. The fourth new type of cooling device 340_1 and the fifth new type of cooling device 340_2 may be wired to the RMS 363.

[0110] The cloud server 200 may receive temperature and humidity data including temperature information (additionally, humidity information) collected by the temperature sensor 330 through the communication circuit 310, and receive information about the communication traffic volume of the fourth type telecommunication building 304 through the RMS. In addition, the cloud server 200 may collect outdoor air data corresponding to the location of the fourth type telecommunication building 304, and generate first control information for controlling the old type cooling device and second control information for controlling the new type cooling device. The cloud server 200 may send the first control information to the first individual controller 311a to the third individual controller 311c through the communication circuit 310 and the communication hub 361. The cloud server 200 may send the second control information to the fourth new type cooling device 340_1 and the fifth new type cooling device 340_2 through the RMS 363.

[0111] As described above, the fourth type telecommunication building 304 according to the embodiment of the present invention can not only operate an independent separate controller to control the old type cooling device, but also control the new type cooling device using the RMS 363. Here, if the old type cooling device is a fixed speed on / off cooling device, and the new type cooling device is a cooling device capable of changing the degree of cooling, effective temperature regulation of the telecommunication building can be supported by operating the old type cooling device and the new type cooling device alternately or in combination. For example, the cloud server 200 can independently or intermittently operate the fourth new type cooling device 340_1 and the fifth new type cooling device 340_2, while basically operating the first old type cooling device 340a to the third old type cooling device 340c. For example, the cloud server 200 can operate only the first old type cooling device 340a to the third old type cooling device 340c until the communication traffic volume increases and exceeds the specified amount, and when the communication traffic volume increases and exceeds the specified amount, at least one of the fourth new type cooling device 340_1 and the fifth new type cooling device 340_2 can be selectively operated. Alternatively, the cloud server 200 can divide the fourth type telecommunication building 304 into three control areas, place the old cooling devices 340a, 340b and 340c in the control areas respectively, place the new cooling devices 340_1 and 340_2 between the three control areas, and then selectively operate at least one of the new cooling devices 340_1 and 340_2 based on the predicted heating value of the control area (or the control area with electronic devices that enter an overheating state due to increased communication traffic).

[0112] Figure 8 is a diagram showing an example of a configuration of an administrator terminal according to an embodiment of the present invention.

[0113] Reference Figure 8, the administrator terminal 100 may include a communication interface 110 , an input / output unit 120 , a memory 130 , a display 140 , and a processor 150 .

[0114] The communication interface 110 (or communication circuit) may support forming a communication channel of the administrator terminal 100. In this regard, the communication interface 110 may include a communication circuit or a communication chip corresponding to at least one communication generation. For example, the communication interface 110 may include at least one of a 3G communication circuit, a 4G communication circuit, and a 5G communication circuit. The communication interface 110 may receive information related to the operation of the cooling system 300 from the cloud server 200. For example, the communication interface may receive cooling system operation information related to the temperature adjustment of at least one cooling device provided in the control area to control cooling according to the predicted communication traffic. The communication interface 110 may send an air conditioning control signal (e.g., a control signal for temperature adjustment of at least one cooling device included in the cooling system 300) input through the input / output unit 120 (or the display 140) to the cloud server 200 through the network 51.

[0115] The input / output unit 120 may include at least one input tool for supporting the input function of the administrator terminal 100 and at least one output tool for supporting the information output function of the administrator terminal 100. For example, the input tool of the input / output unit 120 may include a touch key, a touch pad, a physical button, a mouse, etc. In addition, the input / output unit 120 may include a microphone associated with supporting a voice input function. In addition, when the display 140 is configured as a touch screen, the display 140 may be a component of the input / output unit 120. The output tool of the input / output unit 120 may include, for example, an audio device capable of outputting an audio signal, a vibration module capable of outputting a signal of a specific vibration pattern, an LED or a lamp capable of outputting a specific color of light, etc. The input / output unit 120 may receive an administrator's input for manually controlling a set temperature of at least one cooling device among a plurality of cooling devices included in the cooling system 300 deployed in a telecommunication building, and then send the received administrator's input to the processor 150.

[0116] The memory 130 may store at least one program related to the operation of the administrator terminal 100 and data required for the operation of the program. For example, the memory 130 may store an operating system required for the operation of the administrator terminal 100, operation information of the cooling system 300, and an application supporting at least one of air conditioning control of the cooling system 300.

[0117] The display 140 may support the display function of the administrator terminal 100. The display 140 may output various screens required for the operation of the administrator terminal 100. For example, the display 140 may output at least one of a home screen, a screen for accessing the cloud server 200, and a screen related to the operation of the cooling system 300. Regarding the operation of the cooling system 300, the display 140 may output at least one of a cooling system setting information screen and a cooling system operation status screen. The display 140 may be provided in the form of a touch screen, in which case the display 140 may be used as an input tool of the input / output unit 120.

[0118] The processor 150 may control the processing and transmission of signals required for the operation of the administrator terminal 100, the storage of various information, and the like. The processor 150 of the present invention may control the formation of a communication channel with the cloud server 200 through the network 51 in response to the operation of the user, and receive a screen related to the operation of the cooling system 300 supported by the cloud server 200 and output it to the display 140. For example, the processor 150 may receive cooling system setting information from the cloud server 200 in the operation information of the cooling system 300, and output it to the display 140. The processor 150 may receive the administrator's input of the temperature adjustment of at least one cooling device of the cooling system 300 through the cooling system setting information, and then send a corresponding control signal to the cloud server 200. In addition, the processor 150 may request the operation status of the cooling system 300 from the cloud server 200 in response to the input of the administrator, and upon receiving information on the operation status of the cooling system from the cloud server 200, control the output of the information to the display 140.

[0119] In another example, the processor 150 may collect outdoor temperature values ​​(or outdoor temperatures) in the area where the telecommunication building is located from a weather agency server that provides weather information, and use electronic devices deployed in the telecommunication building to learn past monthly / weekly / daily business usage. The processor 150 may collect information about control areas managed by a plurality of cooling devices included in the cooling system 300, and manage the temperature of the electronic devices for each control area. That is, when the administrator terminal 100 is configured to replace the function of the cloud server 200, the cloud server 200 is replaced by Figure 1 The above structure is excluded, and the administrator terminal 100 can receive cooling-related information of the telecommunication building, predict the communication traffic, predict the outdoor temperature, and control the temperature of at least some cooling devices accordingly.

[0120] Fig. 9 is a diagram illustrating an example of a screen interface provided in a cooling system operating environment according to an embodiment of the present invention.

[0121] Reference Fig. 9 , a screen interface provided in the operating environment of the cooling system according to an embodiment of the present invention may be generated in the cloud server 200 and provided to the administrator terminal 100. The administrator terminal 100 may receive the screen interface from the cloud server 200 and output it to the display 140.

[0122] The display 140 may output, for example, cooling system setting information 1010. The cooling system setting information 1010 may include, for example, a recommended setting field 1011, a set temperature field 1012, and a setting field 1013. The recommended setting field 1011 may be a field that outputs a value calculated based on the predicted outdoor temperature and predicted communication traffic collected by the cloud server 200 to optimally operate the cooling system 300.

[0123] The set temperature field 1012 may be a field indicating a current set temperature state of a specific cooling device associated with the cooling system setting information 1010 among the plurality of cooling devices.

[0124] The setting field 1013 may be a field where an administrator can enter a temperature adjustment for a particular cooling device associated with the cooling system setting information 1010. The administrator may manually adjust the temperature of the particular cooling device by touching the setting field 1013.

[0125] The control transmission button 1014 may be a software button (or a virtual object output on the display 140) for transmitting a control signal for temperature adjustment of the cooling device input through the setting field 1013 to the cloud server 200 (or the cooling system 300). When the control transmission button 1014 is touched, the administrator terminal 100 may transmit the information input in the setting field 1013 to the cloud server 200.

[0126] Furthermore, although the screen interface is described as being provided by the cloud server 200, the present invention is not limited thereto. For example, the screen interface may be generated and output by an application installed on the administrator terminal 100 itself based on cooling related information provided by the telecommunication building.

[0127] Fig.10 is a diagram illustrating another example of a screen interface provided in a cooling system operating environment according to an embodiment of the present invention.

[0128] Reference Fig.10 , a screen interface provided in the operating environment of the cooling system according to an embodiment of the present invention may be generated in the cloud server 200 and provided to the administrator terminal 100. The administrator terminal 100 may receive the screen interface from the cloud server 200 and output it to the display 140.

[0129] The display 140 may, for example, output information about the operating state of the cooling system from the cloud server 200. In this regard, the administrator terminal 100 may receive only numerical values ​​related to the operating state of the cooling system, generate a graph as shown in the figure based on the received numerical values, and output it to the display 140. Alternatively, the administrator terminal 100 may receive graph information from the cloud server 200 and output the received graph information as is to the display 140. In addition, if a temperature higher than a predetermined value is detected when outputting the operating state, the administrator terminal 100 may highlight and output the relevant portion so that the administrator can easily recognize it.

[0130] The operation status graph output by the display 140 may include, for example, power amounts and temperature values ​​detected during a specified time period. Based on the administrator's input, the administrator terminal 100 may request operation status information for different time zones from the cloud server 200, and update the screen of the display 140 to output the operation status information for different time zones.

[0131] In another example, the administrator terminal 100 may collect only a segment having a predetermined amount of power or more or a segment having a predetermined temperature value or more and output the collected information to the display 140 .

[0132] Fig.11 is a diagram illustrating an example of a device operation method of a cloud server related to an operation of a cooling system according to an embodiment of the present invention.

[0133] Reference Fig.11 , regarding the device operation method of the cloud server according to the embodiment of the present invention, in step 1101, the server processor 250 of the cloud server 200 may collect the predicted future outdoor temperature. For example, the server processor 250 may access the meteorological agency server to collect the outdoor temperature at the location of the telecommunication building (e.g., 301, 302, 303) in which the cooling system 300 is deployed, and calculate the predicted outdoor temperature based on the current time and season. Alternatively, the server processor 250 may derive the temperature value under at least some of the same or similar conditions of the location of the telecommunication building, the current time, the weather, and the season from the cumulative outdoor temperature table pre-stored in the server memory 230 through comparative analysis, or collect the predicted outdoor temperature under the same or similar conditions from the meteorological agency server. Alternatively, the server processor 250 may calculate the outdoor temperature at a specific future time point (e.g., a few minutes or hours from now) based on the previous temperature value collected by the temperature sensor placed outside the telecommunication building and the weather, time, and season information when the temperature value is stored.

[0134] In step 1103, the server processor 250 may calculate the predicted traffic volume of the electronic device (or communication service processing device, service processing server device) set in the specific control area. In this regard, the server processor 250 may store and manage the accumulated information about the communication traffic volume of the electronic device set in the telecommunication building, and based on this, calculate the predicted traffic volume under the same or similar conditions. For example, the server processor 250 may calculate the predicted communication traffic volume after a specific time (e.g., a few minutes or hours later) from now by referring to the previous history of the communication traffic volume at the same or similar time, day of the week and season, or in the case of a specific problem.

[0135] In step 1105, the server processor 250 may set the temperature of the first cooling device of the control area based on the predicted outdoor temperature and the predicted traffic volume. Here, the set temperature of the cooling device determined by the server processor 250 may be calculated in consideration of overheating prevention and minimum power of the electronic device. For example, the set temperature may be a specific temperature value between overheating and overcooling, set to a temperature value at which the electronic device can achieve optimal efficiency, or a temperature value at which the electronic device can achieve optimal efficiency as defined in the specifications of the electronic device (or a midpoint between the minimum and maximum values ​​of a specific temperature range).

[0136] In step 1107, the server processor 250 may send the determined set temperature to a first cooling device in the control space. Here, the first cooling device may be a device configured to discharge cooling air primarily to the control space. The control space settings of each cooling device may also be performed by the manager when arranging the cooling devices.

[0137] In step 1109, the server processor 250 may collect temperature information of the control area. In this regard, the telecommunications building operates temperature sensors disposed at a plurality of locations, and the server processor 250 may collect temperature information from a temperature sensor located in the control area among the plurality of temperature sensors. Here, each temperature sensor has identification information, and the server processor 250 may distinguish temperature information provided by a temperature sensor placed in the control area of ​​the first cooling device based on the identification information of the temperature sensor pre-matched for each control space.

[0138] In step 1111, the server processor 250 may check whether there is an electronic device in the control area that has entered an overheated state. For example, if the collected temperature information of the control area indicates a temperature value higher than a specified temperature value, the server processor 250 may determine that the electronic device in the control area has entered an overheated state.

[0139] If the temperature information is different from the overheating state entry of the electronic device, the server processor 250 may check whether there is an electronic device entering an overcooling state among the electronic devices in the control area in step 1113. In this regard, the temperature information indicating the overcooling or overheating state may be predefined.

[0140] If the temperature information of the control area is a temperature value that does not indicate an overcooling state, in step 1115 , the server processor 250 may control the first cooling device of the control area to maintain the operation at the previously determined set temperature.

[0141] On the other hand, if there is an overheated electronic device in step 1111, the server processor 250 may check whether the set temperature of another second cooling device affecting the cooling of the control area is adjustable in step 1117. For example, if the temperature information is a temperature value indicating an overheated state of the electronic device, the server processor 250 may check whether the set temperature of the second cooling device is adjustable.

[0142] If the set temperature of the second cooling device is not adjustable, the server processor 250 may further adjust the set temperature of the first cooling device in step 1119. For example, if the current set temperature of the second cooling device is a predetermined minimum temperature, the server processor 250 may determine that adjustment of the set temperature of the second cooling device is not possible.

[0143] If the set temperature adjustment of the second cooling device is possible, the server processor 250 may check whether the set temperature of the first cooling device is higher than the set temperature of the second cooling device in step 1121. If the set temperature of the first cooling device is higher than the set temperature of the second cooling device, the server processor 250 may further adjust the set temperature of the first cooling device in step 1119. For example, the server processor 250 may control the set temperature of the first cooling device to further reduce the preset temperature.

[0144] If the set temperature of the first cooling device is lower than or equal to the set temperature of the second cooling device, the server processor 250 may adjust the set temperature of the second cooling device in step 1123. For example, the server processor 250 may control the set temperature of the second cooling device to be further reduced.

[0145] On the other hand, if there is an overcooled electronic device in step 1113, the server processor 250 may check whether the set temperature of another third cooling device affecting the cooling of the control area is adjustable in step 1125. If the set temperature adjustment of the third cooling device is not possible, the server processor 250 may adjust the set temperature of the first cooling device in step 1119. For example, if the set temperature of the third cooling device has reached a predetermined upper threshold, the server processor 250 may determine that the temperature adjustment of the third cooling device is not possible.

[0146] If the set temperature adjustment of the third cooling device is possible in step 1125, the server processor 250 may adjust the set temperature of the third cooling device in step 1127. For example, the server processor 250 may control the set temperature of the third cooling device to increase the specified temperature. In another example, the server processor 250 may compare the set temperatures of the first cooling device and the third cooling device that affect the cooling of the control area, and control the set temperature of the cooling device that is set relatively low to increase.

[0147] As described above, the cooling function control method for a telecommunication building according to one embodiment of the present invention sets the operating temperature of the cooling device to consume minimum power while preventing the heat-generating electronic device (or server) from overheating based on the predicted outdoor temperature and predicted traffic volume at the time of control. The higher the predicted outdoor temperature and the larger the predicted traffic volume, the lower the set temperature can be set.

[0148] The present invention described above is used to prevent overheating and overcooling of multiple air conditioners, and can collect the predicted outdoor temperature and predicted traffic volume of an electronic device (or a server device processing communication traffic) controlled by a specific cooling device. In this process, the present invention can derive the predicted traffic volume by learning based on past traffic volume.

[0149] The above can be performed for all multiple air conditioners Fig.11 The steps described in the method enable all multiple air conditioners to operate at appropriate set temperatures, thereby preventing the occurrence of overheated and overcooled servers (or electronic devices) and reducing unnecessary energy usage caused by the operation of multiple air conditioners.
