Abstract
En 中文
Internet of Things (IoT), as an emerging technology, brings effective means for interacting with the physical world and the digital world for monitoring and control applications of building automation. IoT actuators and IoT sensors for building process control are often configured and integrated within one network, which causes high network traffic, competition, and uncertainty for multiple nodes in accessing the network. This article, therefore, proposes a novel IoT architecture adopting a dedicated “edge control network” for robust process control in buildings at the field level. A dedicated wireless network is configured for each process control loop as an “edge control network,” in which the IoT actuator acts as the coordinator, and IoT sensors act as the end devices. An upper-level wireless network is configured to communicate with different “edge control networks,” IoT sensors not engaged in process control loops, and the field gateway. Experimental tests are conducted to evaluate the communication and control performance in comparison with conventional network architecture. When controllers with constant parameters and adaptive parameters are implemented using the proposed architecture, the average integral absolute errors (IAEs) are reduced by up to 14.98% and 13.44%, respectively, under high loads. In addition, the energy consumption of battery-powered IoT sensors is optimized to extend the operating lifetime by about 8.3 times.
