Figure FDA0003366807070000041
when the value l of the distance detection unit is acquired, the existence of other vehicles in front of the vehicle is judged, and the length calculation module is used for calculating the length of the vehicle according to the formula:
Figure FDA0003366807070000042
calculating to obtain the speed v of the automobile exceeding the speed v required by starting the tail wing when the automobile runsOpenerThe starting extension length value i of the tail wing, wherein imaxIs the maximum extension value of the tail wing, vmaxThe maximum length value of the tail fin is required when the tail fin reaches the maximum extension length valueA wheel speed value; through the formula, the specific values of the transverse length of the tail wing under the condition that the front of the automobile has the automobile when the automobile runs are respectively calculated, wherein the formula shows that the rainfall value j is larger and the differential speed value V with the front is larger when the speed V of the automobile is fasterDifference (D)The larger the transverse length of the tail wing, the larger the transverse length of the tail wing is affected, so that more counter-lift force can be provided to ensure stable running.
10. A blockchain based wind energy production control system according to claim 9, wherein: the step S4 further includes the steps of:
step S41: the starting control unit acquires an electric signal of a starting empennage;
step S42: starting a control unit to perform transverse extension of the tail wing;
step S43: the length adjusting unit acquires an output value of the length calculating module;
step S44: the length adjustment unit adjusts the elongation of the tail wing.
