Embodiment Construction

[0046] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0047] refer to figure 1 As shown, the method proposed by the present invention is divided into two parts: planning and execution. The planning part is responsible for analyzing input data, creating a real-time model of the construction project, identifying and evaluating dangerous work areas in the model and creating DVF; the executing part is responsible for processing real-time data , detect risks, generate warnings and improve security precautions.

[0048] 1. Project planning stage

[0049] 1. Decompose tasks: According to the project schedule, use WBS and task duration to decompose the construction project tasks, create a hierarchical structure of project tasks and subtasks; form a specific task sequence according to the start date, end date and duration of subtasks, Such as figure 2 shown.

[0050] 2. Build the model: Based on...

Abstract

The invention discloses a construction site safety risk identification, assessment and prevention method comprising the following steps: S1, creating a real-time model of a construction project, identifying and assessing a dangerous work area in the real-time model, and creating a DVF; and S2, acquiring real-time data of a construction site, detecting the safety risk of the construction site according to the real-time data and the DVF, generating a warning, and perfecting safety precautions. Through the method, the construction process of a dynamic project can be visualized in real time, unknown risks can be identified and assessed, safety precautions can be strengthened, and the safety of the construction site can be improved. A BIM semi-finished product model can be created with the project advances. Risks can be identified in phases, and the accuracy is higher. The safety risk of a construction site can be identified, assessed and prevented in real time. The working state of workers can be monitored in real time. Once there is a worker approaching a danger area, the alarm is raised immediately. The precaution consciousness of workers is improved. A real-time and effective building construction safety management system is formed.

Description

technical field [0001] The present invention relates to a construction site safety risk identification, evaluation and prevention method, in particular to a construction site safety risk identification and evaluation based on BIM (Building Information Modeling, building information model) and RTLS (Real Time Location Systems, real-time positioning system) and preventive methods. The invention belongs to the field of virtual reality, real-time positioning technology and engineering risk identification and evaluation fields. Background technique [0002] The identification of accident hazards on construction sites is an important issue in the construction industry. A large number of close work tasks, unpredictable and uncontrolled activities have increased the accident rate on construction sites. Compared with other industries, the construction industry has the highest accident rate, especially falls, collisions and mechanical accidents, so it is necessary to install fences, ...
