The invention relates to a positioning device and
system for real-time monitoring of construction site personnel information. The
system comprises a positioning
label attached to a constructor, a positioning
base station, a resolving service center
station and a background
management system. The positioning
label is attached to a safety helmet; the positioning
label enters a
signal coverage rangeof the positioning
base station and automatically establishes connection with the positioning
base station, and the positioning base
station completes acquisition of positioning data according to a built-in rule, transmits the positioning data to a resolving service center through data message
middleware for resolving, calculates an actual position of the positioning label and stores the actual position into an entity
database; the background
management system displays the positions of all people in the area in real time through an
electronic map, monitors the dynamic state of people, and masters the number of people and the real-
time distribution condition. Based on equipment information collection and reporting, the functions of personnel positioning, track playback, intelligent uncapping detection, safety helmet unwearing monitoring and the like are achieved, safety accidents caused by personnel retention negligence are effectively eradicated, and the
construction site safety accident occurrence frequency is reduced.
