In the aspect of construction supervision, along with diversification of monitoring modes, the prior art provides many different types of solutions for supervision problems of constructors. Because the traditional supervision mode needs a large amount of manpower and material resources, the supervision through equipment is the most important supervision mode for modern construction. However, there are many problems with supervision through the device, such as: the supervision range is not in place, the supervision effectiveness can not be guaranteed, the supervision function is limited, and the like.
In order to solve the above problems, the reference CN106385563B proposes a real-time monitoring system for a construction site, in which a monitoring device disposed on the site is connected to a management platform and interacts with a safety helmet to monitor constructors and construction tasks, and this solution solves some problems of construction monitoring to some extent, but still has the problems of easy drilling during monitoring, poor monitoring effect, and the like. Therefore, the prior art still has no good solution to the problem of how to effectively and safely supervise the constructors through the management platform.
