2results about How to "Effective early warning" patented technology

This invention discloses a method and system for accident rescue risk early warning based on real-time calculation. The method includes: when a collapse accident occurs and rescue is required, acquiring surrounding rock parameters, collapse body parameters, and a expected rescue plan; constructing a finite element model based on the surrounding rock parameters, collapse body parameters, and expected rescue plan, and using the excavation advance of the expected rescue plan as the calculation advance; loading a seepage model onto the finite element model based on the expected groundwater level and initializing the steady-state seepage field, and then performing excavation simulation calculations through the finite element model; performing excavation simulation calculations in each round using the calculation advance; conducting rescue operations according to the expected rescue plan, and adjusting and recalculating the parameters of the finite element model and seepage model based on data detected during the rescue operation; when the calculation result of the finite element model exceeds the warning value, determining that there is a risk in the current rescue operation.

The utility model relates to a parking space anti -collision technical field especially, it is a kind of electric vehicle charging positioning anti -collision mechanism, its technical scheme includes: underframe, the underframe is installed with fender subassembly, warning subassembly is installed on the fender subassembly, the fender subassembly is rotatably installed with underframe, adjusting subassembly is installed on the fender subassembly, and the adjusting subassembly is used to adjust the rotation angle of fender subassembly on underframe;The warning subassembly includes pressurized air bag, and pneumatic horn is installed on the pressurized air bag.The utility model has the advantages of effective early warning and buffer collision, solves the problem that vehicle tail and charging pile collide and cause vehicle and equipment damage and security risk.
