A Smart Building Design using Cyber-Physical System Modeling

Due to the demand for IoT technologies, the concept of CPS was explored in this paper. CPS refers to the coordination and communication of physical processes and computing elements connecting the physical and digital worlds. With the increasing number of smart buildings, the researchers considered the automation control of various facilities in a smart building which are air conditioning, lighting, and surveillance systems for sustainability. With this, the researchers acquired and analyzed the STEER Hub building’s layout diagram as the basis of a smart building design. It was verified and evaluated by an ocular visit, and the total number of existing system devices for air conditioning, lighting, and surveillance was 313. Wireless access points connect these devices to the internet. The network architecture was designed and simulated in Cisco Packet Tracer. Meanwhile, the aforementioned systems were modeled and simulated in MATLAB® and Simulink®. A digital signal, signifying the On/Off condition, serves as the output of the air conditioning and lighting systems. Meanwhile, the surveillance system’s output is a waveform that compares the motion intensity to a threshold value. The captured picture displaying the total number of source and captured frames were also presented.
