Acquiring a hazard occurrence value of a target foundation pit and a soil hazard value of a place where the target foundation pit is located;
setting the object weight of an object to be borne in the edge area of the target foundation pit, and calculating to obtain the hidden danger radiation value of the target foundation pit;
hidden danger radiation radius of the target foundation pit is calculated according to the hidden danger radiation value;
constructing a hidden danger area of the target foundation pit according to the hidden danger radiation radius by taking the edge position of the target foundation pit as a starting point;
the comprehensive management module sends the hidden danger area of the target foundation pit to the display terminal, the display terminal is used for displaying the hidden danger area of the target foundation pit, and a user avoids according to the hidden danger area when placing articles.
10. A management method for intelligent management of foundation pits in urban construction sites, characterized in that based on the intelligent management system of foundation pits in urban construction sites according to any one of claims 1-9, the method comprises the following steps:
step S101, a data acquisition module acquires foundation pit basic information of a target foundation pit and foundation pit soil information of a place where the target foundation pit is located in an urban construction site, the foundation pit basic information and the foundation pit soil information are sent to a foundation pit analysis module, and the foundation pit soil information is sent to a soil analysis module;
Step S102, a soil analysis module analyzes the soil condition of the place where the target foundation pit is located, if the soil condition is analyzed to generate three-level foundation pit signals, the three-level foundation pit signals are sent to a comprehensive management module, and if the soil risk value of the target foundation pit is obtained through analysis, the three-level foundation pit signals are sent to a foundation pit analysis module;
step S103, analyzing the comprehensive condition of the target foundation pit by the foundation pit analysis module, analyzing and generating a foundation pit health signal and foundation pit danger signals of different grades, and sending the signals to the comprehensive management module;
And step S104, the comprehensive management module carries out comprehensive management on the target foundation pit according to different signals, simultaneously constructs a hidden danger area of the target foundation pit, and sends the hidden danger area of the constructed target foundation pit to the display terminal for display.
