Research on Metro Station the Blind Zone of Camera Surveillance Based on"BIM+Simulation"
The traditional construction plan design of the surveillance camera is mainly based on previous experience using two-dimensional design method,it is unable to simulate the monitoring area of surveillance camera.When the terminal devices are obscured so that they cannot be pass security acceptance,it is necessary to increase the number of camera deployment,and results in decoration being demolished and leading to an increase in the construction period and construction cost.In order to solve the blind zone issue in surveillance camera,a method of analyzing the simulation of camera surveillance based on BIM technology was studied.The technique includes creating BIM model of the target building,deploying surveillance camera,determining the field of view area of the camera and reasonable surveillance area,analyzing the factors affecting the obstruction of objects around the surveillance camera,etc.By applying this technology,monitoring areas and blind zones could be marked out,and the distribution of camera monitoring ranges could be mapped to confirm that there was no blind zone.The technology simulated the monitoring range of surveillance cameras and analyzed the blind zones,and effectively solving the problem of the blind zones of surveillance camera and realizing the integration of BIM technology and the security monitoring profession.It realized the security requirements of'without dead ends and complete coverage for monitoring',which improved the construction drawing design and construction quality of monitoring camera in urban rail transit projects,high-speed rail stations,aviation airports and shopping malls,reduced construction costs,and improved the safety management level of project operations.
