Intelligent construction site visual positioning management system based on Internet of Things

Abstract

The invention relates to an intelligent construction site visual positioning management system based on the Internet of Things, and the system comprises a positioning management system, a WLAN wireless network communication system, a label unit and a plurality of triggers. The triggers send RF ID signals to activate the label unit in a signal coverage area of the triggers; and the WLAN wireless network communication system is respectively connected with the positioning management system and the label unit. The triggers are installed at entrances and exits of construction sites, construction posts and fence positions, wrist strap products in the tag units are worn on wrists of building workers, wrist straps transmit positioning signals and upload the positioning signals to the positioning management system by using a WLAN, the positioning management system calculates the positions of the building workers by combining SSS I and TDOA positioning technologies, and marks the positions on a map, so the management and control capability and management efficiency of the intelligent construction site are effectively improved.

Description

technical field [0001] The present invention relates to the technical field of management systems, in particular to a smart construction site visual positioning management system based on the Internet of Things. Background technique [0002] Smart construction site refers to the use of information technology to carry out precise design and construction simulation of engineering projects through a three-dimensional design platform, and to establish an interconnected, collaborative, intelligent production, and scientifically managed construction project information ecosystem around the management of the construction process. Under the virtual reality environment and the engineering information collected by the Internet of Things, data mining and analysis are carried out, process trend prediction and expert plans are provided, and visual intelligent management of engineering construction is realized, so as to improve the level of engineering management informatization, so as to ...

AI Technical Summary

Problems solved by technology

However, this kind of personnel inspection plus camera video surveillance and alarm mode cannot fully effectively locate and manage construction workers, and there is still a certain gap compared with the actual work needs of the construction site.

Personnel inspection is an active defense, and it is difficult to conduct real-time inspections, especially at night; video surveillance is a passive defense, mainly used to provide video playback, and it is impossible to associate events with personnel

This will inevitably reduce the management efficiency, the construction workers will not work efficiently, and the construction period will be extended.
