Distributed wireless system for tower crane monitoring

The goal of this project is to develop a wireless distributed system for monitoring and predictive maintenance of tower cranes. The system will increase the security at work in this field since it is able to predict potential failures and to assess the risk of fall of the crane. The system consists on a set of wireless sensors (to measure load, wind speed, etc ) transmitting data to an acquisition and signal processing unit located close to the crane. The sensors and the unit communicate to each other using the ZigBee standard. Finally the signal processing unit transmits data (using a GPRS modem) to a remote host that performs monitoring and predictive maintenance. A prototype of this system has been successfully developed.
