Combination of radio frequency identification (RFID) and field verification tests of interior decorating materials

In recent years, Radio Frequency Identification (RFID) has been considered an important technology affecting the development of industries around the world and is valued in many fields. In the construction industry, RFID benefits construction engineering and management by improving efficiency and control. This study describes the influence of combination manners of RFID and interior decorating materials on RFID system recognition by identifying appropriate combination manners and tag space layouts. The main study results include (1) building materials' influence on effects of RFID, (2) readable distance between tags and readers, and (3) electronic wave penetration of passive tags.

RFID 3D location sensing algorithms

Effective monitoring of personnel movements, material locations, and construction equipment has always been a topic of concern in construction management. Radio Frequency Identification (RFID) technology has been proven to increase efficiency for staff and materials management. The objective of this study is to develop a Three-Dimensional (3D) location sensing algorithm using RFID technology to analyze the possible location of objects. To achieve this goal, this research first establishes an indoor wireless sensing network to collect Received Signal Strength Indication (RSSI). The distance between the antenna and target tag is calculated based on RSSI. The gradient decent method is then used to calculate the location of the electronic tag. The feasibility of this 3D positioning algorithm is verified using a real case. The experiment proves that the location sensing algorithm established in this study can gradually approach the actual location of the target tag. This research is one of the first studies for 3D location sensing with RFID application in the construction industry. The proposed RFID 3D sensing algorithm can be used to assist construction managers in locating the positions of relevant personnel, equipment, apparatus and materials, enhancing management efficiency and safety.

First, the frequency of particular type of objects is analyzed based on vast historical accident cases. Next, this paper analyzes the proactively preventive information requirement of struck-by-falling-object accidents and brought forth an integrated information management model. Furthermore, considering the crucial and controllable objects, an integrated information management model is proposed. This study would provide a possible approach for tracking struck-by-falling-object accidents based on real-time information for proactive prevention and could serve as a foundation for further study.
