Research on wireless sensor network node for tower crane safety monitoring system

Based on the status of tower crane safety monitoring for construction project, the Internet of things technology is applied for tower crane safety monitoring and early warning system, the WSN nodes are designed for displacement, stress and distance monitoring function. Through the wireless transceiver module CC2530, field monitoring data are uploaded timely and accurately to the monitoring center PC, for real-time display and processing. If the monitoring data exceeds the alarm value, the alarm signal will be sent out immediately, to prevent tower crane accidents effectively, and ensure the safe of crane operation. By the network debugging, WSN node performance is reliable, and the measuring data is accurate. It has high performance to price ratio and application value.
