Safety Monitoring of Construction Equipment based on Multi-sensor Technology

The growth in the size and the level of complexity of construction equipment imposes tremendous hazards in construction sites. Any breakdown or failure of such systems may not only cause the delay in construction but also lead to the loss of life and properties. To address these issues, this paper proposes an intelligent monitoring system based on multi-sensor technology, which consists of multiple sensor clusters, signal transmission and data acquisition systems, condition evaluation, identification and alerting systems, assisted by Wifi or Zigbee wireless transmission technology to obtain the real-time state data from various parts of construction equipment. The center computer can manage and analyze the relevant parameters to reveal the safety reserve of the tower crane, scaffolds, self-climbing platform and other construction equipment in a visual image. In addition, the alerting alerts can be sent directly to security officers and operators to respond to and avoid accidents. Lastly, the intelligent multi-sensor monitoring system is simulated tested in 6013 flat crane, which is shown the workflow of whole technology and demonstrates this technology is fast, accurate and valid for the safety management of construction.
