BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 It is a flow chart of the closed-loop control method of construction safety risk based on BIM technology of the present invention. DETAILED DESCRIPTION

[0019] The invention provides a closed-loop control method for construction safety risks based on BIM technology. Figure 1 As shown, the following steps are included:

[0020] S1. Establish a construction management BIM model, and add a safety risk source library to the construction management BIM model, wherein the safety risk source library includes unsafe behaviors of people, unsafe states of objects, and unsafe factors of the environment, to obtain a construction safety risk management BIM model;

[0021] Specifically, the unsafe behaviors of people include not wearing a safety helmet, working at height without a safety rope, working under a hoisted object, working in an unsafe environment, etc.; the unsafe conditions of objects include mechanical equipment without necessary protective devices and improper placement of materials, etc.; the unsafe factors in the environment include high slopes, insufficient illumination, and bad weather outdoors, etc.

[0022] S2. Obtain on-site construction data and bind the on-site construction data with the construction safety risk management BIM model;

[0023] Specifically, the on-site construction data is for each construction section, that is, each part in the construction safety risk management BIM model. The on-site construction data of the construction section includes on-site monitoring data, on-site photos taken and manually entered safety risk source data. For on-site photos, on-site managers can take photos and upload them.

[0024] S3. Use the trained AI intelligent recognition algorithm model to determine whether there are safety risk sources in the on-site construction data in the construction safety risk management BIM model, and distinguish and display the BIM model areas corresponding to the existing safety risk sources;

[0025] Specifically, the AI ​​intelligent recognition algorithm model is trained by using existing construction safety risk information, and the construction safety risk information includes on-site construction data and its corresponding safety risk sources; such as using photos, monitoring data or manually entered safety risk source data as input, and unsafe behaviors of people, unsafe conditions of objects and unsafe factors of the environment as output, to train the AI ​​intelligent recognition algorithm model to obtain an AI intelligent recognition algorithm model that can identify unsafe behaviors of people, unsafe conditions of objects and unsafe factors of the environment from the input data; the color of the construction section where the difference is displayed as having safety risks is inconsistent with the color of the construction section where no safety risks exist. In the construction safety management BIM, the corresponding safety risk source can also be displayed in the BIM model area corresponding to the existing safety risk source.

[0026] S4. Extract risk data based on the BIM model area where there is a safety risk source, match the rectification content based on the risk data, and send the rectification content to the corresponding person in charge;

[0027] Specifically, the risk data includes unsafe behaviors of people, unsafe conditions of objects and unsafe factors of the environment, and the rectification content is the rectification measures for each risk data.

[0028] S5. After receiving the rectification content, the responsible person shall complete the rectification according to the rectification content and upload the rectified data to the construction safety risk management BIM model;

[0029] Specifically, the data after rectification can be collected by video surveillance equipment, Internet of Things sensor equipment, etc. in the construction section, or it can be collected and uploaded by the responsible person.

[0030] S6. Use the trained AI intelligent recognition algorithm model or manual judgment on the rectified data to determine whether the rectification is completed. If the rectification is completed, cancel the distinguishing display of the construction section in the construction safety risk management BIM model; if the rectification is not completed, issue an early warning for the construction section in the construction safety risk management BIM model.

[0031] Specifically, use the trained AI intelligent recognition algorithm model or manual review to check whether the rectification is completed, so as to form a closed-loop control of risk sources.

[0032] In particular, in the construction safety risk management BIM model, statistics are collected on-site construction data of safety risk sources and their corresponding rectification contents and data after rectification. This allows us to intuitively see the location of safety risks, risk data, and data after rectification, thus achieving closed-loop control of safety risks.
