Description

Technical Field

[0001] This invention relates to a TVWS-based intelligent building integrated management server and method, specifically to a TVWS-based intelligent building integrated management server and method, which provides management of various facilities and data within the building, disaster monitoring, and energy efficiency optimization. Background Technology

[0002] Building management systems (BMS) are constantly evolving to automate or efficiently manage various building facilities (such as heating and cooling, lighting, electricity, and access control) by integrating them into a single control platform. For example, sensors within the building measure indoor temperature and humidity, which are then monitored and analyzed in a central control unit, automatically controlling various facilities (air conditioners, heaters, dehumidifiers, etc.). However, these traditional technologies are typically built primarily using wired networks or limited to a single wireless protocol (Zigbee, Wi-Fi, etc.), limiting their ability to provide seamless coverage for large buildings or complexes of buildings.

[0003] The demand for real-time monitoring of various disaster situations (such as fires, earthquakes, and floods) is constantly increasing, while the need to link closed-circuit television video analysis with environmental sensor data (such as temperature, humidity, dust, and harmful gases) is becoming increasingly necessary. For example, when a fire occurs in a specific space, there is a need for a function to detect a sudden increase in sensor temperature values ​​or to identify smoke or flames through closed-circuit television video analysis and immediately send a notification to management personnel.

[0004] There are increasingly more cases where closed-circuit television systems, environmental sensor monitoring systems, and access control security systems are not interconnected and operate independently, making it difficult to comprehensively monitor facilities within buildings, difficult to conduct timely real-time control, and increasingly difficult to develop additional functions or expand systems.

[0005] Furthermore, in many cases, there are differences in network environments between older and newly constructed buildings, or blind spots where wireless transmission and reception are not smooth. For example, in buildings with thick interior walls or complex underground structures, it is difficult to achieve stable connections using existing short-range wireless communication protocols such as Wi-Fi or BLE (Bluetooth Low Energy). Therefore, to achieve energy saving, disaster monitoring, and comprehensive security, wireless network technologies capable of stable coverage over a wider area are needed.

[0006] Therefore, in order to overcome this market demand and technological limitations, it is necessary to research a building management system that can utilize various wireless communication technologies (including the TVWS band) and provide intelligent monitoring, analysis and control on a single platform.

The method may include: calculating an intelligent building control information score; calculating a building comprehensive management optimization score based on a weighted sum of the calculated wireless connection information score and the intelligent building control information score; and generating a building comprehensive management optimization list by sorting the calculated building comprehensive management optimization scores in descending order.

[0016] This includes: adjusting the basic maintenance plan based on the value calculated by subtracting the building management optimization score from the predetermined key building management optimization score, and multiplying that value by an adjustment sensitivity coefficient (calculated as the ratio of the number of warnings or error notifications during the predetermined monitoring period), thereby calculating the adjusted maintenance plan.

[0025] Descriptions of well-known technical aspects within the scope of this invention that are not directly related to it will be omitted. This is to more clearly convey the essence of the invention without obscuring it by omitting unnecessary explanations.

[0026] For the same reason, some components in the accompanying drawings are exaggerated, omitted, or depicted schematically. Furthermore, the dimensions of each component do not perfectly reflect its actual size. In each drawing, the same or corresponding components use the same reference numerals.

The functionality provided in components and "subcomponents" can be combined into a smaller number of components and "subcomponents," or further separated into additional components and "subcomponents." Furthermore, components and "parts" can be implemented to regenerate one or more CPUs within a device or secure multimedia card.

[0031] In the embodiments of the present invention, examples of specific systems will be used as the main subject, but the key points claimed in this specification can be applied to other communication systems and services with similar technical backgrounds without obviously departing from the scope disclosed in this specification, and this can be determined by those skilled in the art.

[0032] Figure 1 This is an example diagram illustrating the operating environment of a TVWS-based intelligent building integrated management server according to an embodiment of the present invention.

[0033] refer to Figure 1 The TVWS-based intelligent building integrated management server 100 (hereinafter referred to as "server 100") can provide wireless connection information and intelligent building control information through user terminal 10.

[0034] Here, user terminal 10 is a desktop computer, laptop computer, notebook computer, mobile phone, tablet computer, smartwatch, smart glasses, e-book reader, PMP (portable multimedia player), portable game console, navigation device, digital camera, DMB (digital multimedia broadcasting) player, digital recorder, digital audio player, digital video recorder, digital video player, or PDA (personal digital assistant) with communication capabilities.

[0035] In addition, server 100 can connect to external big data server 110 via wired or wireless network to receive wireless connection information and intelligent building control information, and external server 110 can be integrated with server 100 or provided in the cloud.

[0036] Here, wireless connectivity information may include shadow reduction rate, communication range, latency, packet loss rate, frequency utilization efficiency, overlap coverage, simultaneous connection throughput, data transmission speed of encryption methods, security authentication success rate, intrusion detection response speed, data processing volume, average accuracy of AI analysis, anomaly detection rate, and monitoring video stream latency.

[0037] Here, intelligent building control information can include temperature deviation limits, humidity deviation limits, fine dust concentration change rate, solar irradiance prediction accuracy, ventilation volume control response speed, indoor air quality improvement rate, renewable energy utilization rate, heating and cooling energy consumption reduction rate, lighting automatic control energy saving rate, equipment control response speed, predictive control accuracy, maintenance cost reduction rate, IoT device linkage rate, and energy utilization efficiency improvement rate.

[0038] Here, wired and wireless networks can include various communication methods, such as Bluetooth communication, BLE (Bluetooth Low Energy) communication, Near Field Communication (NFC), WLAN communication, Zigbee communication, Infrared Data Association (IrDA) communication, WFD (Wi-Fi Direct) communication, UWB (Ultra-Wideband) communication, Ant+ communication, WIFI communication, and RFID (Radio Frequency Identification) communication, and are not limited to these.

[0039] On the other hand, when server 100 receives wireless connection information, it can classify the wireless connection information into at least one category based on at least one attribute.

[0040] Next, server 100 can calculate wireless connection information scores by cross-linking the wireless connection information classified into various categories.

[0041] On the other hand, when the server 100 receives intelligent building control information, it can classify the intelligent building control information into at least one category based on at least one attribute.

[0042] Next, server 100 can calculate the intelligent building control information score by cross-linking the intelligent building control information classified into various categories.

[0043] The immigration consultation optimization score is calculated by weighting the wireless connectivity information score and the intelligent building control information score.

[0044] In addition, the generated building integration management optimization scores can be sorted in descending order to generate a building integration management optimization list, providing users with the optimized building integration management.

[0045] Figure 2 This is an example diagram illustrating the operation of a TVWS-based intelligent building integrated management server.

[0046] See the reference image. Figure 1 and Figure 2 Server 100 can utilize wireless communication networks, including the TVWS (TV Blank Band) band, to monitor, analyze, and control various facilities and sensors within a building in real time.

[0047] Specifically, server 100 communicates with multiple gateways 210 and TVWS IoT communication terminals 220 to collect and analyze data generated from building facilities 240 (such as cooling and heating equipment and monitoring 230), thereby providing stable wireless connectivity and efficient facility management services without any blind spots within the building.

[0048] Server 100 integrates and analyzes real-time environmental data (such as temperature, humidity, air quality, dust, etc.) and monitoring images obtained from sensors within the building, and then automatically controls building equipment 240 based on the results, thereby achieving energy saving and safe operation. Furthermore, by utilizing the TVWS frequency band (e.g., 470–510 MHz), it can stably cover long-distance or shaded areas that are difficult to reach with existing short-range communications (BT, Zigbee, etc.), and can provide a secure wireless communication environment by applying the highest level of security.

[0049] Server 100 can communicate with multiple gateways 210 and TVWS IoT communication terminals 220 to collect, store, and analyze various sensor and facility data.

[0050] For example, server 100 can store and analyze data such as temperature, humidity, dust, and energy usage transmitted in real time from large IoT devices.

[0051] At this point, server 100 can apply intelligent algorithms to optimize device operation modes or perform fault prediction (predictive maintenance) through machine learning / AI analysis (e.g., based on TensorFlow, PyTorch).

[0052] Furthermore, server 100 connects to gateway 210 via TCP / IP and can handle authentication and encryption (e.g., TLS / SSL, IPSec) during communication with TVWS IoT communication terminal 220. Server 100 can achieve efficient energy operation by monitoring renewable energy usage and providing reports (energy usage trends, savings effects, carbon footprint analysis, etc.), thereby providing energy reports (RE100 contribution).

[0053] For example, message queuing systems such as Apache Kafka or RabbitMQ can be used to process sensor data streams within server 100, and data visualization dashboards can be configured through the Elastic Stack (Elasticsearch, Logstash, Kibana).

[0054] Gateway 210 serves as an intermediate bridge between server 100 and TVWS IoT communication terminal 220, relaying and linking various wired and wireless networks within a building. At this time, gateway 210 can send and receive data with server 100 via wired Ethernet, Wi-Fi, or a dedicated embedded module, using a TCP / IP-based communication method. Furthermore, gateway 210 can interconnect with TVWS IoT communication terminal 220 using a 470-510MHz frequency band, thereby providing long-distance, blind-zone communication.

[0055] In addition, the gateway 220 is wirelessly connected to the closed-circuit television 230 installed in the hazardous area to collect and transmit images. The server 100 can analyze the images in real time (e.g., detect objects, identify abnormal operations) and provide notifications to the administrator.

[0056] Multiple gateways 210 can coexist and be placed on different floors and in different areas of a building to distribute network load and eliminate shadow areas.

[0057] For example, on gateway 210, modules configured as Docker containers (data acquisition, Edge AI module, network routing module, etc.) can be executed to perform real-time data preprocessing or caching functions on-site.

[0058] The TVWS IoT communication terminal 220 is a terminal that directly connects wirelessly to building equipment 240, sensors, closed-circuit television, etc., and can provide long-distance, low-power communication using the TVWS (470-510MHz) frequency band. The TVWS IoT communication terminal 220 adopts... Figure 2 The TVWS (802.15.4m) standard shown is based on the 802.15.4m communication method and can support a transmission speed of about 200Kbps and a communication distance of about 1km.

[0059] At this point, in order to address shadow areas, even in areas where existing BT and Zigbee technologies are difficult to reach, the low-frequency characteristics of TVWS can ensure excellent obstacle penetration and coverage.

[0060] At this point, protocols such as AES-CCM, TLS, and IPSec can be applied to ensure the secure transmission of sensor data and control commands, achieving the highest level of security. Furthermore, if necessary, multiple TVWS IoT communication terminals 220 can form overlapping coverage to provide network stability, ensuring communication continues even if one terminal fails. These TVWS IoT communication terminals 220 can be implemented using 802.15.4m chipsets or white space radio modules (such as Carlson Wireless) developed by Texas Instruments or NXP.

[0061] Surveillance camera 230 is a surveillance camera used in hazardous areas to monitor for fires, intrusions, and disasters within buildings. It can connect to gateway 210 or a standalone IoT communication terminal 220 to provide video data. It can connect to gateway 210 via LAN cable or wirelessly (Wi-Fi / 5G), and in some sections, it can be relayed via TVWS IoT communication terminal 220.

[0062] At this point, the video stream is transmitted to server 100, where AI-based object and operation analysis is performed, and notifications can be provided in the event of anomalies (e.g., detecting a person falling, detecting a flame, etc.). Meanwhile, when CCTV 230 is transmitting video using TVWS bandwidth (hundreds of Kbps), it can effectively utilize limited bandwidth by periodically transmitting low-rate MJPEG / H.264 / H.265 streaming media or image snapshots. Furthermore, distributed CCTV systems can be integrated and managed, for example, by using commercial software such as Milestone VMS or Genetec, and video analysis can be performed via AI plugins linked to server 100.

[0063] Building equipment 240 includes core building infrastructure equipment such as air conditioning, air conditioning facilities, lighting, elevators, and security systems, which can be controlled in real time through TVWS IoT communication terminal 220.

[0064] Building equipment 240 wirelessly transmits data generated by sensors (temperature, power, vibration, etc.) installed on each device so that server 100 can determine its operating status or abnormal conditions. Meanwhile, TVWS IoT communication terminal 220 transmits commands such as temperature control, fan operation, and lighting brightness adjustment from server 100 so that the operating mode of the device can be changed immediately.

[0065] For example, a wireless approach can be implemented for existing industrial protocols by connecting Modbus RTU-based sensors / controllers to the TVWS Gate module. It can also connect to commercial PLCs (Programmable Logic Controllers) or BEMS (Building Energy Management Systems).

[0066] Therefore, server 100 can ensure a stable connection with areas that are difficult to cover by existing short-range communication such as Wi-Fi and BLE via TVWS, and centralize sensor information and monitoring images in server 100, thereby enabling real-time monitoring of the entire building's status and automatic implementation of energy and security strategies.

[0067] In addition, intelligent analysis can be used to optimize heating, cooling and lighting control, generate environmental energy operation reports such as RE100 achievement rate, and flexibly respond to the expansion of building scale or linkage with other facilities by additionally deploying TVWS IoT communication terminals 220 and gateways 210, and operate safely through top-level security.

[0068] Therefore, server 100 can provide the technical effect of effectively monitoring large-scale IoT facilities by building a wireless network utilizing TVWS within the building, and reduce building operating costs and energy use based on intelligent analytics.

[0069] The method according to the invention can be implemented in the form of program commands, which can be executed by various computer devices and recorded on a computer-readable medium. The computer-readable medium may contain program instructions, data files, and may include data structures, etc., individually or in combination. The program instructions recorded on the computer-readable medium may be program instructions specifically designed and configured for this invention, or program instructions known and available to those skilled in the art of computer software.

[0070] Examples of computer-readable media may include hardware devices specifically configured to store and execute program instructions, such as ROM, RAM, flash memory, etc. Examples of program instructions may include machine language code (e.g., code generated by a compiler) and high-level language code that can be executed by a computer using an interpreter. The hardware device may be configured to operate in conjunction with at least one software module to perform the operations of the present invention, and vice versa.

[0071] In addition, the method or apparatus can be implemented individually by combining all or part of its configuration or functions.

[0072] The present invention has been described above with reference to preferred embodiments; however, those skilled in the art should understand that various modifications and variations can be made to the present invention without departing from the spirit and scope of the invention as set forth in the following claims.
