As the fundamental equipment for lifting, cranes are widely used in metro and underground construction. Crane related contact collision is a major safety issue faced by these construction activities. From 2004 to 2006, there were over 600 construction worker deaths related to construction equipment and contact collisions in the United States. Crane related accidents have become more serious in large scale metro and underground construction projects with increasingly complex environment, sensitive urban infrastructure and migrant workers with poor safety awareness on construction site. In order to address the challenges presented by such projects, safety monitoring systems to reduce the likelihood of human errors in metro and underground construction projects are highly recommended to improve safety during crane operations.
Dr. Cheng Zhou, who came from HUST in China as a visiting scholar to UMD, introduced the Internet-of-Things-based portable and agile monitoring system for blind hoisting in metro and underground construction. This innovative system can collect all the information about hazards of blind hoisting on underground construction site very easily, accurately and reliably, which also has data analysis and early warning mechanism in real-time. The Internet-of-Things-based portable and agile monitoring system for blind hoisting is a proactive controlling system for isolating hoisting hazard energy and preventing accident on metro and underground construction sites, which is totally different from the manual and experience based safety monitoring approaches. The core of the system is a portable and agile IoT suitcase with IoT-based monitoring devices which can easily and conveniently support a 360˚ and real-time monitoring network anywhere and anytime.
