Attendance system, method and device used for construction site

Abstract

The invention relates to an attendance method, device and system used for a construction site. The method comprises the following steps: acquiring a range of a constructor in the construction site, atime point that the constructor just leaves away the construction site and a time point that the constructor enters the construction site again after just leaving away the construction site as well ascorresponding images; and acquiring and recording the actual positions and facial images shot by attendance equipment specific to the same constructor in the range of the construction site, at a moment that the constructor leaves away the range of the construction site for the first time and at a moment that the constructor arrives at the construction site for the first time after leaving away the range of the construction site for the first time as well as corresponding shooting time points, and calculating a time period of the constructor outside the construction site. The attendance method, device and system used for the construction site are convenient for accurately controlling the construction site by an enterprise or unit, inconvenience caused by the traditional manpower supervision and attendance is avoided, and supervision and development of the enterprise are benefited.

Description

technical field [0001] The invention relates to the field of intelligent attendance checking, in particular to an attendance checking method, device and system acting on a construction site. Background technique [0002] With the continuous progress of society and the rapid development of science and technology, more and more enterprises should carry out reforms and innovations in a rapidly developing society, such as strengthening the internal attendance management system of enterprises. The time attendance machines in the prior art are in various forms such as punch card, fingerprint recognition, and head portrait recognition. The time attendance machine using fingerprint recognition, construction workers work on the construction site, because they are exposed to a lot of dust and dirt during get off work hours, and the fingerprint recognition often fails when they clock in after work. Due to the dust on the construction site, the dust floats into the time attendance machin...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the limitations of the construction site, it is difficult for management personnel to supervise and manage the construction site at the first time, resulting in adverse effects of inadequate supervision;

[0005] 2. Most of the existing attendance equipment is based on equipment or devices to record attendance, and the hardware is prone to functional damage due to the harsh conditions of the construction site
