Description

Method for Constructing and Maintaining IoT Network Infrastructure for Smart Buildings The present invention relates to a network infrastructure design that supports seamless communication between various IoT devices within a smart building and implements an efficient maintenance process, and in particular, to a communication infrastructure and related maintenance technology equipped with stability and scalability in an IoT network environment. Smart buildings utilize IoT devices to provide energy savings, efficient resource management, automated security, and convenience. To achieve this, real-time data transmission and reception between various IoT devices within the building is essential. However, establishing an integrated network infrastructure is difficult due to the diverse types of IoT devices and their differing communication methods. While wireless networks generally play a primary role, a hybrid network incorporating both wired and wireless connections is required for seamless communication among the various devices within the building. Existing IoT networks often suffer from interoperability issues between various devices, making operation and maintenance tasks difficult for building managers. Furthermore, some smart building networks focus on individual devices or single networks, making it difficult to monitor the status of the entire network in real time or resolve issues quickly during maintenance. To address this, an integrated network infrastructure is required that can efficiently support communication between IoT devices and enhance the efficiency of maintenance operations. FIG. 1 is a network configuration diagram in which various IoT devices (300, 400), such as temperature sensors, lighting control, HVAC, and security devices, are connected via wired and wireless communication through local gateways A and B (200, 201) and managed in an integrated manner, centered around a central management server (100) of an IoT-based smart building. The main embodiment of the present invention is to configure a network infrastructure to enhance communication stability and maintenance efficiency within an IoT-based smart building. This infrastructure consists of the following key modules, each of which provides efficient data transmission between IoT devices within the building, ease of maintenance, and centralized management functions. 1. Network Architecture Design Various IoT devices within smart buildings are classified by zone according to their communication range and function. IoT devices include a wide variety of items such as temperature sensors, lighting controllers, access security devices, energy management sensors, HVAC systems, and CCTVs; to ensure stability and security during data transmission and reception, the following network layer structure is designed. IoT Device Layer: This layer houses IoT devices deployed in each zone of the building, which detect temperature, humidity, illuminance, energy consumption, and entry/exit status in real time and collect data. These devices utilize various sensing frequencies to maintain signal reliability. Local Gateway Layer: Data collected from the IoT device layer is transmitted to the local gateway of the corresponding area. The local gateway possesses data processing capabilities, filters the data, and forwards it to the central server. The local gateway also identifies the status of devices in a specific region to detect abnormal conditions and monitors the communication stability of that area. Central Management Server Layer: Processes and analyzes data transmitted from the local gateway to provide a dashboard that offers a comprehensive overview of the smart building's overall status. Additionally, the central management server integrates with the energy management system, security monitoring system, and HVAC control system to support efficient building operations and provides remote control capabilities for devices across all layers. 2. Establishment of a network combining wired, wireless, and satellite communications In this invention, communication stability is enhanced by combining wired, wireless, and satellite communication methods as the communication method for an IoT network within a smart building. Wired Communication: Wired networks are used for devices where security is critical or for transmitting and receiving large amounts of data, and are installed in locations requiring network stability. Reliability is maximized by applying wired methods to data centers, security control devices, and server communications. Wireless Communication: Wireless networks are primarily utilized for small sensors installed within buildings or devices requiring mobility. Wireless communication methods such as Wi-Fi, BLE (Bluetooth Low Energy), and Zigbee are used, enabling the efficient collection of data, mainly from temperature, light intensity, and security sensors. Satellite Communication: Satellite communication is established as a network back
