Large-scale Cranes often need to run in a long-term working time, and result in various potential structural health risks. To reduce these risks, we herein design structural health monitoring system of the crane (SHMC for short) with Narrow Band IoT (NB-IoT). Firstly, we design a monitoring terminal for the SHMC system, wherethe single-chip microcomputer controls the electronic device to collect external signals to monitor the crane information in real time. Secondly, we employ NB-IoT based the wireless transmission module for network bandwidth-saving and long-term running. Then, we design a core platform, which parses and calculates the information uploaded by the terminal, and stores it in the database. Our system can monitor the running status of cranes in real time, and timely diagnose the fault information of crane to ensure their safe operation. Also the implementation of our design with apache storm cluster, Kafka server and Alibaba EC2 web server is showed in this study.
