Demo Abstract: Towards a Wireless Building Management System with Minimum Change to the Building Protocols

Abstract

Abstract-We develop a wireless system that can (partially) substitute the wired infrastructure underlying Building Automation and Control network (BACnet) of the Building Management System (BMS). There exists effort (e.g., from ZigBee alliance) to develop wireless components for BMS, while they build from bottom up which may lead to change and re-standardization of a new BACnet protocol. There are entirely new infrastructure proposed (e.g., sMAP) to collect physical information. These schemes require a longer time to be adopted. Our system does not need any modification of BACnet. We believe that our design experience is useful for other applications where wired infrastructure and a complete set of upper layer protocols exist; and it is now considered cost-effective to convert the system to (partially) wireless.Our experience shows that a direct replacement of wires to wireless links does not work. There are a number of difficulties, including a strict time constraint for a frame to exist before the system consider it as outdated. Our solution is to propose an asynchronous-response framework so as to keep the control flow of the upper layer protocol intact. In the demo we will 1) bring the physical devices and explain our system on site and 2) show a video of a real world experiment of our system.

ZigBee wireless smart plug network with RSSI multi‐lateration‐based proximity estimation and parallelised machine learning capabilities for demand response

“…This study explores how wireless ZigBee technology may be applied to the automation of electric loads in residential and commercial spaces, allowing them to participate in DR initiative. The authors discuss the development of a custom smart plug with sensing, wireless communication, and electric load actuation capabilities along with RSSI multi‐lateration‐based proximity estimation and parallelised machine learning capabilities for electric load automation and DR [1–6]. The viability of both proposed methods is supported by experimental test results presented in Sections 5.3 and 6.3.…”

“…The authors discuss the development of a custom smart plug with sensing, wireless communication, and electric load actuation capabilities along with several innovative upgrades as outlined in the Section 1.2.Load automation and DR are important topics in the field of electrical engineering. DR may be utilised to increase or decrease the consumption of individual power system loads based on actual or projected electricity costs [1–6] The objective is to operate non‐essential loads that perform time‐insensitive tasks at times (e.g. late night) when electricity prices are low, providing customers an opportunity to reduce their average billing rate.…”

IAQSense

“…Building Automation and Control Networks (BACnet) is the most common communication protocol in BMS, our previous work has shown the approaches in retrieving the data from application layer [8] and datalink layer [5]. In this demo, we extend our work into the application of IAQ enhancement.…”

Carrying My Environment with Me

“…Building Automation and Control Networks (BACnet) is the most dominant communication protocol in BMS nowadays. In our previous work, we have shown two different methods to communicate with BMS, i.e., using software [18] in application layer or smart sensors [15] in datalink layer. We believe our design of CarryEn that based on BACnet is able to work in most of the buildings today.…”
