Design of Crane Strain Acquisition System Based on ZigBee

Article Preview

Abstract:

A crane strain acquisition system based on ZigBee wireless sensor network and WiFi is built to monitor the stress state of the cranes in real-time. The star topology is selected as the wireless communication architecture. The endpoint nodes are responsible for acquiring the strain data sampled by a time to digital converter PS021, and then sending the data to the gateway. The Gateway collects the data from the endpoint nodes and transfers the data to the host computer through WiFi network. Furthermore, the strain data are analyzed with the monitoring software. The static and dynamic strain data of a cantilever beam are obtained with the system, and the results show that the system works properly and is proved to be useful and feasible to monitor the crane stress state.
