Description
Technical Field
The invention relates to a rainfall simulation technology, in particular to a movable artificial rainfall simulation method based on an unmanned aerial vehicle platform.
Background
At present, the main artificial rainfall simulation experiments in China are artificial rainfall simulation halls and traditional movable artificial rainfall simulation devices, and both the two methods can be used for artificial rainfall simulation experiments. The artificial rainfall hall is built in a closed house, and a fixed rainfall main part (a rainfall pipeline and a spray head), a power supply system, a rainfall control system, a water supply system and a runoff sediment collecting device are arranged at the roof; the rainfall main part of the system is an immovable part, different underlying surface conditions need to be manually laid (soil is taken, vegetation is transplanted or vegetation is planted) according to the surface parts of the field, the soil is generally taken as undisturbed soil and placed at a certain position on the earth surface, and then the vegetation is transplanted according to the spatial position, the vegetation coverage and the vegetation height of the vegetation where the vegetation is also planted. After the arrangement is finished, manual maintenance is needed, and rainfall simulation tests can be carried out after precipitation of rainwater irrigation for a certain time meets the requirements of the field natural environment. Soil taking, vegetation planting or transplanting and later maintenance need a large amount of manpower and a certain long time to meet the conditions, and waste time and energy. And soil destroys original structure easily in the removal, can cause experimental husky data of producing to a certain extent and bigger, and the data result is inaccurate. The time for stable soil precipitation and vegetation maintenance is long for 3 months and 1-2 years if the soil is long for achieving the accurate effect; if the simulation of the ground surface with a plurality of underlying surfaces is realized, a plurality of underlying surface conditions are required to be set. The field rainfall simulator is arranged above a field fixed sample plot, and the sample plot part utilizes a natural sample plot, so that the problem of the arrangement part of the underlying surface ground surface is solved. The common field rainfall simulation device generally comprises a rainfall simulation part, a rainfall control system, a power supply system, a water supply device and a runoff sediment collection part, wherein the components of the device are the same as those of an artificial rainfall simulation hall, and the device can be assembled and used in the field and arranged above a field fixed sample plot, and the rainfall simulation is completed by utilizing a natural underlying surface. Compared with a manual rainfall simulation hall, the rainfall simulation hall has the advantages that the setting of an underlying surface and the planting or transplanting of vegetation are omitted. But the simulation area of the rainfall simulation in the field is generally 5m multiplied by 2m or 10m multiplied by 5m; the height of the simulator is about 5m; the rainfall simulator has the advantages that the simulation area is too small, the gradient length of a coverage area is not enough, the runoff converging path of rainfall on the ground is short, a complete converging process is not formed, the difference between simulation and real runoff converging is large, the representativeness of a simulation result is poor, and most of the simulation time is used for instrument carrying, assembling and sample plot replacement. If a standard runoff plot is made to realize rainfall simulation, the slope length of 22.13m is required (Qiluhua, 2011), and the rainfall simulator is at least 23m long, so that the mobile advantage of the field rainfall simulator is obviously lost. Meanwhile, the simulator cannot make rainfall reach free fall height, the free fall speed needs to be achieved through pressurization of a control system, and the requirement on a rainfall control system is higher. At present, the required raininess is achieved by pressurizing through the diameter of a spray head and a control system, the pressure is too high, the initial falling speed of raining raindrops reaches the requirement, but the raininess is increased only by the time rainfall amount; if the water outlet of the spray head is reduced, raindrops at the water outlet are reduced to form atomization. Coordinating the relationship between pressure, meeting aperture and rain intensity is difficult, typically by modifying the meeting, but never as satisfactory. At present, a rainfall control system of a field rainfall simulation device can generally simulate common rainfall intensity, but when the rainfall control system is used for simulating, only one fixed rainfall intensity can be controlled by one-time rainfall. In the process of natural rainfall, the rainfall intensity can change along with time, and the research on the rainfall intensity of the rainfall produced on the downhill surface is limited by the rainfall simulator and cannot be realized. At present, the research on the sand production in the runoff production under the fixed rainfall intensity is basically completed, and the research on the sand production in the runoff production under the variable rainfall intensity is urgently needed.
Therefore, although the rainfall hall can realize free falling of rainfall raindrops, the rainfall hall is immovable, needs to rebuild a mat surface, wastes time and labor, has long ground surface remodeling process time, and has difficult effect to meet the requirements of natural slope surfaces in a short period; although the movable artificial rainfall simulation device solves the problem that the equipment is moved to the field from a laboratory, the natural underlying surface can be utilized, the problem of repeated slope surface is solved, the operation area of the movable artificial rainfall simulation device is convenient to move, the requirement of the lowest standard slope runoff length cannot be met, the runoff converging and reality difference in the simulation process is large, and the difference between the simulation result and the real rainfall runoff sand is large. The rainfall simulator is difficult to move and transport when the sample plot is changed on the slope surface, the simulation area of the instrument is limited by the coverage area of the instrument, and most of the simulation time is used for carrying, assembling and sample plot changing of the instrument. The natural rainfall process is a rainfall intensity change process, the current artificial rainfall simulation can only simulate the effect of fixed rainfall intensity, and the rainfall intensity change in the rainfall process cannot be realized.
Therefore, a method, a technology or auxiliary equipment for simulating rainfall is urgently needed, a rainfall simulation test can be carried out by utilizing the underlying surface of a natural slope, the rainfall simulation test can overcome the defects that the rainfall range is small, the rainfall height is low, and the raindrop point cannot reach the raindrop splashing erosion force generated by free falling, and the rainfall process with nearly natural variation of raininess can be simulated, namely, the raininess can be changed along with time in the same rainfall process, so that the simulation result is closer to the real effect, the processes of disassembling, carrying and assembling when the simulation field is changed for artificially simulating the rainfall device can be omitted, and the rainfall simulation efficiency can be improved.

s111, dividing a rainfall area into at least three sub-areas, and meanwhile, taking at least three unmanned aerial vehicles to correspond to the at least three sub-areas (in the scheme, three unmanned aerial vehicles are taken as an example, as shown in figure 3);
s112, setting a flight route in each sub-area, arranging all unmanned aerial vehicles in the corresponding sub-areas to fly according to the set routes, and synchronously spraying simulated rainfall in the flight process;
wherein, unmanned aerial vehicle flying height all is at 10-30m, the rainfall that all unmanned aerial vehicle sprayed is different, and, two adjacent subregions do not have coincidence region in border department, unmanned aerial vehicle in two adjacent subregions sprays the edge of scope mutually not coincide (because the different raininess of simulation in the three subregion is, belong to independent simulation test, consequently, the spraying border of three subregion can not coincide, just can simulate accurate different raininess, guarantee that every independent subregion's border department can not produce the mixed raininess of coincidence), the advantage of this kind of mode lies in can accomplishing bigger flight area in the short time.
