Real-time and non-intrusive on-site diagnosis for commissioning wireless sensor and actuator networks in building automation

Abstract

Abstract Wireless Sensor and Actuator Networks (WSANs) are widely used in Building Automation Systems (BASs). The field commissioning of WSANs is generally considered to be time consuming and labor intensive. To increase the efficiency of commissioning process, an on-site diagnosis is extremely important. In this paper, a novel real-time and non-intrusive on-site diagnosis (OSD) for WSANs in BASs is proposed. It implements Out-of-Band Bluetooth Low Energy (BLE) to transmit diagnosis information without interference on the normal traffic of the BA field network, which has been validated through experiments. By proper utilization of our OSD system, installers can obtain a comprehensive knowledge of the network, which make commissioning much more efficient and cost effective.
