The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1 and fig. 2, a construction site high formwork intelligent monitoring and early warning system based on a digital twin technology comprises a monitoring point creating module, a monitoring point management module, an information acquisition module, a threshold management module and a monitoring and early warning module, and the implementation steps of the intelligent monitoring and early warning system are as follows:
monitoring point creating module
The monitoring point creating module is used for receiving basic information of any externally imported high formwork sub-region, wherein the basic information at least comprises a project period, position information, a number of the associated high formwork sub-region and all contained structural components, wherein the project period and the position information are of the high formwork sub-region.
Firstly, importing high formwork related information for preprocessing, wherein the preprocessing is divided into 2 steps, firstly, screening corresponding monitoring objects from all structural components of a high formwork subregion by combining basic information, and analyzing the monitoring objects to obtain monitoring parameters, corresponding parameter thresholds and related monitoring object numbers of each monitoring object; and secondly, creating a new monitoring point by combining the basic information and the analysis result of the high formwork, and allocating unique monitoring point numbers and monitoring object numbers to the monitoring points and the monitoring objects.
For example, a building project under construction is divided into three building areas according to a high formwork structure: the building comprises a region A, a region B and a region C, and the high formwork structures of the three building regions have associated influence. Under the condition that the 3 building areas are constructed simultaneously, the project periods, the position information, the associated high formwork sub-area numbers and the structural components contained in the high formwork areas of the area A, the area B and the area C are respectively led in through the monitoring point creating module. The method comprises the steps of supposing that corresponding intelligent wireless data acquisition terminals, pull rope type displacement sensors, shaft pressure sensors, inclinometers, wireless cameras, laser deflection meters and the like are screened out from all structural components of the high formwork sub-area by combining basic information of the area A, analyzing the monitored objects of the area A to obtain corresponding vertical rod inclination, vertical rod axial force, template settlement, template horizontal displacement, casting surface vertical displacement, foundation settlement and integral horizontal displacement related monitoring parameters, corresponding parameter thresholds and related monitoring object numbers, and allocating unique monitoring point numbers and monitoring object numbers to monitoring points and monitoring objects of the area A.
Second, monitoring point management module
And the monitoring point management module is used for receiving the created monitoring points and monitoring objects and sending the related data information to the threshold value management module and the monitoring early warning module for analysis and processing.
Third, threshold value management module
And the threshold management module receives and processes the related data sent by the monitoring point management module, and calculates the parameter threshold of each monitored object in the current threshold management period by combining the basic information of each monitored object in the current threshold management period and the real-time monitoring parameters of the corresponding related monitored object.
For example, in the removal of the high-branch formwork, the threshold management module readjusts the threshold parameter according to the change of the relevant removal parameter, such as the removal of the upper half of the high-branch formwork in one area, the load-bearing information of the high-branch formwork area in the lower half will be recalculated and adjusted, and the partial parameters of the high-branch formwork area in the associated area will be recalculated. Or in the foregoing example, if the partial parameter threshold of the high formwork in the area B or the area C is affected before and after the high formwork in the area a is removed, the threshold management module automatically adjusts the partial parameter threshold of the area B or the area C according to the existence condition or the removal progress of the high formwork in the area a.
Fourth, monitoring and early warning module
The monitoring early warning module receives real-time monitoring parameters of the monitored object, collected by the sensors arranged on the monitored objects in the high formwork sub-area, and performs early warning judgment processing on data of the monitored point and the monitored object by combining the parameter threshold of the monitored object in the current threshold management period. If the monitoring and early warning module judges that the alarm value is exceeded, the monitoring and early warning module pushes an alarm state and an alarm position.
As shown in fig. 3, the alarm state and the alarm position corresponding to the high-support monitoring object are pushed to the mobile terminal or the web end through the wireless communication module, and the mobile terminal or the web end can automatically refresh the display data of the high-support monitoring point and the monitoring object in real time.
For example, after the building is built, a high formwork region of an outer wall is dismantled, a side plate in the high formwork region deforms, the monitoring and early warning module carries out early warning judgment processing after receiving data, the monitoring point and the monitored object can be displayed through a graphical interface or a mobile terminal, if the monitoring and early warning module calculates and judges that warning reminding needs to be given, the monitoring and early warning module can send early warning state, the monitoring point and the monitored object information to relevant responsible persons and synchronously display the information on the graphical interface or the mobile terminal.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
