Design of wireless sensor networks for safety monitoring at civil engineering construction sites

Civil engineering construction site is a high-risk area, where many accidents occur, but most construction sites lack necessary safety monitoring and warning system. Compared to traditional monitoring system, the monitoring system based on wireless sensor networks has many advantages. According to the requirements of practical engineering, the safety monitoring system for civil engineering construction is designed based on wireless sensor networks. The structure of system, network topology, and architecture of the wireless sensor nodes, hardware design, performance test and the architecture of information fusion are presented.
