Construction site personnel positioning system based on WSN

Abstract

The invention discloses a construction site personnel positioning system based on a WSN and belongs to the monitoring technology field. The system comprises a monitoring server host, a client computer, anchor nodes, a moving node, a GIS system, a positioning software platform system and a construction personnel positioning APP software system. The anchor nodes are arranged in a construction site and each anchor node comprises a positioning module and a communication module. Moving node equipment is worn by a construction person. Personal basic information is arranged in the moving node. The anchor nodes and the moving node form bidirectional communication. The positioning module collects moving node information according to a preset time interval. The monitoring server host is connected toeach anchor node and the moving node. The client computer is used for inputting basic data, and inquiring and displaying collected moving node data. In the invention, the WSN is used to position theconstruction person in real time. On a computer terminal and a mobile phone terminal, construction site personnel positioning can be checked in real time so that management efficiency is greatly increased.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to a WSN-based construction site personnel positioning system. Background technique [0002] At the construction site, managers need to know the distribution of personnel in real time to facilitate the management of the construction site. In the traditional personnel management mode, due to the scattered areas, multiple people are required to manage the site, and it is impossible to know the distribution of personnel in real time, the specific location of personnel cannot be determined, and it is difficult to know whether there is any unauthorized departure during work; In a dangerous situation, there are a series of problems such as the inability to effectively determine the location of the personnel in a timely manner, and the inability to view the historical trajectory information of the personnel.

Problems solved by technology

The traditional personnel management mode requires many people to manage the site due to the scattered areas. It is impossible to know the distribution of personnel in real time, and the specific location of personnel cannot be determined. In a dangerous situation, there are a series of problems such as the inability to effectively determine the location of the personnel in a timely manner, and the inability to view the historical trajectory information of the personnel.

[0003] The traditional personnel management mode is not only low in management efficiency, but also cannot fundamentally solve the problem of supervising every personnel

Most of the current positioning systems use UWB or ZigBee networks. Although they can also realize the function of personnel positioning, the existing problems are also more prominent: the UWB spectrum is not flexible, the spectrum utilization efficiency is not high, and the information transmission rate is not high. It is obvious; while ZigBee has relatively high cost, short communication distance, poor penetration and other issues that cannot be ignored.
