Overview of Smart Building Solutions
The application requirements of smart buildings are a very broad field, including communication automation systems (CAS), building automation systems (BAS), office automation systems (OAS), security automation systems (SAS), integrated wiring systems (GCS), and fire automation System (RAS), etc., each system can be subdivided into several specific functional requirements, such as: data communication system, monitoring system, office information service system, automatic alarm system…
Smart building solution design concept
In this smart building solution, the design standard of the wireless network refers to the hierarchical design idea of the Internet of Things, which is divided into three basic levels: the sensor layer, the network layer, and the application layer according to the Internet of things. Standard design for all aspects of network transmission and application development.
Sensing layer design standards-most of the sensor components are low-power, low-data flow devices, and there are many communication protocols, including zigbee, infrared, Bluetooth, RS232, RS485, TCP/IP, etc., according to the unified communication protocol, standard, and interface The principle requires the unified conversion of various communication protocols into WiFi standards to facilitate communication with the WiFi network of the optical carrier wireless switch.
Network layer design standards—According to the WiFi wireless network technical specifications and the area and structure of smart buildings, buildings and parks, install “optical wireless switches” in the central computer room, and install a sufficient number of remote antennas at suitable locations to ensure WiFi The wireless signal covers all experimental areas, reducing wireless interference and eliminating coverage blind spots.
Application layer design standards-complete the software and hardware environment construction in accordance with the main application functions of this program, and use general software development tools for application software development for each application function to ensure the sustainability of subsequent development.
The following content of this plan will focus on how to build an integrated system of optical-carriage wireless network intelligent building under the premise of low cost, high safety, easy construction, efficient management, and easy maintenance.
In buildings where wired LANs have been built, make full use of existing equipment and systems to build wireless networks to meet people’s needs for mobile networks. The optical carrier wireless network is a transparent network for users, network managers, and network developers. It follows the existing network protocol, and the management, maintenance and subsequent application development of the network can be seamlessly connected to the wired network.
Intelligent building group (smart community) solution network structure diagram
In the above figure, the network structure diagram of multiple intelligent buildings in a school park is simulated. The “optical wireless switch” is installed in the central computer room, and the wireless signal is distributed and covered to various areas of the intelligent building group through optical fibers to form WiFi wireless Full coverage of the network. Using this network, many functions such as wireless Internet access, video surveillance, 2G/3G signal coverage, man and vehicle material management, and environmental monitoring can be realized, and various systems can be organically combined. The following figure shows a schematic diagram of the interior of the building and specific scenes.

Smart building asset and access control management wireless network
The three major functional modules of the smart building’s video surveillance, logistics management and environmental monitoring will be described in detail below. Each large functional module can be subdivided into several sub-functions, corresponding to the main application requirements of intelligent buildings.
a) Video surveillance
Video surveillance functions are in great demand in the application of intelligent buildings, including security monitoring, personnel management, parking lots, and logistics management.
b) Logistics management
The logistics management function is mainly used in the management of intelligent building personnel, vehicles, materials and equipment. The front-end equipment is mainly RFID radio frequency identification tags and fixed or handheld readers. The reader module converts the read information into a WiFi wireless signal, and transmits it to a nearby remote antenna, and then transmits it back to the application management platform of the management center. The back-end database and application software cooperate to realize the logistics management IoT application.
c) Environmental monitoring
Fire monitoring-mainly through front-end fire monitoring equipment (mainly sensor devices, such as temperature, gas sensors, etc.), the monitoring area is timed or inductively collected, and the collected information is transmitted to nearby remote sites in real time through WiFi. Terminal antenna, and then transmitted back to the control center to show the current monitoring area status with a suitable man-machine interface.
Pollution prevention and control-mainly through front-end gas, humidity and other sensors to monitor the building’s air conditioning, heating, air supply and exhaust, water supply and drainage and other environments, carry out regular or inductive information collection, and transmit the collected information in real time via WiFi To the nearby remote antenna, then transmit it back to the control center to monitor the environmental status of the building in real time.
