And step S104, determining disaster risk levels corresponding to the flood area based on the flood area water flow corresponding to the flood area.
In the embodiment, through the analysis of the flow of the flood area corresponding to the flood area, the river reach which the water level rises and reaches the flood early warning is early warned according to the analysis data; determining the range data of the flood area according to the point location information of the early warning river reach and the geographic data information of the point location information of the river reach, extracting the range data of the flood area, extracting the geographic information data of the flood area, and reporting the disaster early warning; the method comprises the steps of determining the path direction trend of the flood beach according to geographic information data of the flood beach, dividing flood beach risk levels according to paths of the flood beach into different disaster risk levels, for example, dividing disaster risk levels of a flood beach area into a low risk area, a medium risk area and a high risk area.
And S106, determining a disaster relief scheme corresponding to the flood plain area based on the disaster risk level corresponding to the flood plain area through the digital twin simulation model.
In this embodiment, different disaster relief schemes are determined based on disaster risk levels corresponding to different flood plain areas, for example, when the disaster risk levels corresponding to the flood plain areas are high risk, an electronic transfer notification is sent to personnel, the personnel in the area to be transferred are positioned through a mobile device, and the positioned personnel in the area to be transferred are transferred in a fixed point through the mobile device; carrying out statistics and reporting on the number of accommodated people in the transfer personnel placement area by the staff, and generating a material list and planning a transportation path of the material according to the number of people in the placement area and the position of the placement area; meanwhile, a prevention and reinforcement scheme is implemented on the key river reach position of the flood beach, so that continuous flood diffusion of the flood beach is prevented.
Based on the schemes defined in the above steps S102 to S106, it can be known that, in the embodiment of the present invention, a corresponding flood fighting scheme is determined by a digital twin simulation model based on a manner of determining a corresponding disaster relief scheme by a disaster risk level; then determining disaster risk levels corresponding to the flood plain areas based on the flood plain area water flow corresponding to the flood plain areas; and finally, determining a disaster relief scheme corresponding to the flood plain area based on the disaster risk level corresponding to the flood plain area through the digital twin simulation model.
It should be noted that the disaster risk level is determined according to the flow rate of the flood area corresponding to the flood area, so that the timeliness and the accuracy of determining the disaster risk level are improved; and a corresponding disaster relief scheme is determined based on the disaster risk level, so that the timeliness and the accuracy of determining the disaster relief scheme are improved.
Therefore, through the technical scheme of the invention, the purpose of determining the corresponding disaster relief scheme through the disaster risk level is achieved, so that the technical effect of improving the timeliness and accuracy of determining the disaster relief scheme is realized, and the technical problem that the flood plain disaster relief scheme cannot be quickly and accurately generated based on the real-time condition in the related technology is solved.
Further, the system determines the disaster risk level corresponding to the flood area based on the flood area water flow corresponding to the flood area, and the determining includes: the method comprises the steps of obtaining estimated water flow of a flood area through monitoring real-time hydrological information, drainage basin environment monitoring information and meteorological data information of the flood area and based on a water level flow relation obtained by analyzing historical hydrological information, and determining water flow of the flood area according to the estimated water flow; then determining a water flow safety threshold and a water flow danger threshold based on historical hydrological information, wherein the water flow safety threshold is smaller than the water flow danger threshold; comparing the water flow in the flood area with the water flow safety threshold and the water flow danger threshold to obtain a comparison result; and finally, determining the disaster risk level of the flood area according to the comparison result.
Optionally, the water flow safety threshold represents that when the water flow is below the threshold, the risk of the flood beach occurrence is extremely low; the water flow risk threshold represents that when the water flow is above the threshold, the risk of the flood beach is extremely high. And calculating a water flow safety threshold and a water flow danger threshold according to the historical water flow. The estimated water flow is obtained by calculating the water level flow relation, the real-time water level information, the basin environment monitoring information and the real-time meteorological information which are obtained by analyzing historical water flow, the accuracy of the estimated water flow data calculation is verified through the real-time hydrological information, and the calculation parameter data are continuously refreshed.
Optionally, the monitored flood plain area water flow of the flood plain area is compared with the water flow safety threshold and the water flow danger threshold, and a disaster risk level of the flood plain area may be determined, for example, when the flood plain area water flow of the flood plain area is smaller than the water flow safety threshold, at this time, the disaster risk of the flood plain is very low, and the disaster risk level may be determined to be a low risk level.
When needing to be explained, the water flow safety threshold and the water flow danger threshold are determined based on historical hydrologic information, and the disaster risk level is determined by comparing the water flow of the flood plain area with the water flow safety threshold and the water flow danger threshold, so that the timeliness and the accuracy of determining the disaster risk level are improved, the corresponding on-site scheme is determined based on the disaster risk level in the follow-up process, and the timeliness and the accuracy of generating the flood plain relief scheme are further improved.
Further, the system determines a disaster risk level of the flood area according to the comparison result, and specifically determines that the disaster risk level of the current flood area is a first risk level when the water flow of the current flood area is smaller than a water flow safety threshold; when the water flow of the flood plain area of the current flood plain area is greater than or equal to a water flow safety threshold and smaller than a water flow danger threshold, determining the disaster risk level of the current flood plain area as a second risk level; when the flood plain area water flow of the current flood plain area is greater than or equal to a water flow danger threshold, determining that the disaster risk level of the current flood plain area is a third risk level, wherein the first risk level is lower than the second risk level, and the second risk level is lower than the third risk level.
Optionally, when the regional water flow of the current flood plain region is smaller than the water flow safety threshold, determining that the disaster risk level of the current flood plain region is a first risk level, where a disaster occurrence risk corresponding to the first risk level is extremely low and may be defined as a low risk. When the area water flow of the current flood plain area is larger than the water flow danger threshold, determining that the disaster risk level of the current flood plain area is a third risk level, wherein the disaster occurrence risk corresponding to the third risk level is extremely high, namely the flood plain disaster can certainly occur, and the third risk level can be defined as a high risk. When the regional water flow of the current flood plain region is between the water flow safety threshold and the water flow danger threshold, namely the regional water flow is greater than the water flow safety threshold and less than the water flow danger threshold, determining that the disaster risk level of the region is a second risk level. It follows that the second risk level is between a low risk and a high risk, and thus the second risk level may be defined as a medium risk.
It should be noted that the disaster risk level is determined by comparing the regional water flow of the flood plain region with the water flow safety threshold and the water flow danger threshold, so that the timeliness and the accuracy of determining the disaster risk level are improved, and the timeliness and the accuracy of generating the flood plain relief scheme are further improved.
