Embodiment

[0067] refer to figure 1 , a construction site risk early warning method based on BIM and RFID technology, including the following steps:

[0068] 1) RFID risk data collection: Use RFID with electronic tag models to collect temperature, wind speed, pressure on materials, location of materials, current and voltage of mechanical equipment, location of mechanical equipment, and helmet position on the construction site ( In order to judge the location of the personnel) data information, the surface of the items involved in the construction process is attached with an RFID tag, and the radio frequency signal is transmitted through the RFID, and the materials, mechanical equipment, and helmet information attached to the RFID tag enter the magnetic field area where the RFID works. RFID receives radio waves in the magnetic field by coupling, so that the RFID generates an induced current to obtain energy. The RFID will store the temperature, wind speed, pressure on the material, materi...

Abstract

The invention discloses a construction site risk early warning method based on BIM and RFID technology. The method comprises the following steps: 1) performing RFID risk data collection; 2) performingrisk data processing; 3) performing BIM database construction and risk data storage; 4) performing BIM model establishment and BIM database data retrieval; 5) performing collision check; 6) generating a risk report; 7) issuing risk early warning alarm; 8) exporting BIM database historical data; 9) predicting the risk of optimizing the LS-SVM by using a PSO algorithm; and 10) generating a prediction result: generating a risk prediction result of optimizing the LS-SVM by using the PSO algorithm. By adoption of the method, the accurate collection of construction site risk data, the timely transmission of risk information and the effective storage of the risk data are effectively and reliably ensured, and dynamic early warning control and ex ante forecasting avoidance of construction processrisks are achieved.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a construction site risk early warning method based on BIM and RFID technology. Background technique [0002] Engineering construction is complex and long-term, and the risk factors on the construction site are also uncertain and random. The uncertainty and randomness of risk factors pose a greater potential threat to the smooth implementation of the project and seriously affect the construction personnel. The life safety of the project, the construction progress of the project and the social image of the enterprise. [0003] At present, the information transmission in construction management is not timely, the working methods of various departments and types of work are not coordinated, and the phenomenon of rework and delayed work is serious. Building Information Modeling (Building Information Modeling, referred to as BIM), as a new technology in the industry, has visual...
