The unidirectional connection of central control system, ground control system is unidirectional with unmanned plane 1 to be connected, and described communication system is double with earth station system
To connection, earth station system is connected with ground storage system bidirectional, and described storage system is used for storing flying quality, described communication
System is used for carrying out communication with ground control system and earth station system and carrying out signal data alternately with central control system,
Ground control system is used for controlling unmanned plane during flying and controlling wide angle camera zoom and take pictures, then by communication system and ground
Station, face system carries out data exchange, and ground storage system is used for storing image information.
As in figure 2 it is shown, described unmanned plane 1 is provided with wide angle camera 12；Described central control system include micro-control unit,
Power Management Unit, sensor unit and driver element；As in figure 2 it is shown, described water system include Straightway micro-water pump 1,
Water supply hose 5 and water pump control unit, wherein Straightway micro-water pump 1 is connected with water supply hose 5, water pump control unit and direct current
Micro pump 1 connects；Described purging system is formed by cleaning shower nozzle, Straightway micro-water pump 26, water tank 2 and presser unit, institute
State cleaning shower nozzle and include common injector head 8 and high-pressure injector head 9, and be provided with rudder at common injector head 8 and high-pressure injector head 9 end
Machine；As shown in Figure 2 and Figure 3, being provided with reservoir chamber 10 in the middle of described water tank 2, both sides are provided with cleaning solution storeroom 11, in reservoir chamber 10
Equipped with clear water, equipped with cleaning solution in cleaning solution storeroom 11, described common injector head 8 is stored with reservoir chamber 10 and cleaning solution respectively
Room 11 connects, and high-pressure injector head 9 is connected with reservoir chamber 10, and described Straightway micro-water pump 26 is located at reservoir chamber 10 and cleaning solution storage
Hide bottom room 11, be provided with liquid level sensor 7, described presser unit and high pressure at reservoir chamber 10 and cleaning solution storeroom 11 middle and lower part
Injector head 9 connects, and described water tank 2 lower end is provided with water supply hose clamping device 4.
With specific embodiment, specific works mode is illustrated below:
When in work high above the ground, first start each big system, but do not start unmanned plane 1, by water system feed-tank 2
Between reservoir chamber 10 store clear water, then pour cleaning solution in cleaning solution storeroom 11, water supply hose 5 now is with water tank 2 not even
Connecing, then start unmanned plane 1, the real time information returned according to wide angle camera 12 transmission by ground control system controls unmanned plane
1 flight, the real time information then returned according to wide angle camera 12 transmission is gone to adjust the cleaning shower nozzle in purging system, is passed through steering wheel
Adjust common injector head 8 and high-pressure injector head 9, make the place that common injector head 8 and high-pressure injector head 9 are cleaned facing to needs,
After being more than ready to, earth station system first controls reservoir chamber 10 lower end and the Straightway micro-water pump two of cleaning solution storeroom 11 lower end
6 work, according to cleaning environment and cleaning target, control the rotating speed of the two Straightway micro-water pump 26, it is achieved clear water and cleaning solution
The mixing of different proportion, then the mixing liquid of clear water and cleaning solution sprays to object from common injector head 8, is then shut off clear
The Straightway micro-water pump 26 of clean liquid storeroom 11 lower end, is given from reservoir chamber 10 out by the presser unit in purging system
Clear water pressurizes, and is then rinsed object clear water by high-pressure injector head 9, clear by the mixing liquid of clear water and cleaning solution
After washing, then it is cleaned with the clear water of high pressure, it is ensured that the clean level of cleaning, by common injector head 8 and high pressure spray
Penetrating 9 end and be provided with steering wheel, it is achieved that common injector head 8 and the multi-angle regulation of high-pressure injector head 9, clean range is wider, with
The common injector head of Shi Caiyong 8 and the combination of high-pressure injector head 9, and presser unit gives and leads to high-pressure injector head 9 from reservoir chamber 10
Clear water pressurizes, and cleaning efficiency is higher；Clear water and cleaning solution are divided by reservoir chamber 10 and cleaning solution storeroom 11 by setting on water tank 2
Leaving, the different proportion realizing clear water and cleaning solution by controlling the rotating speed of Straightway micro-water pump 26 mixes, to tackle difference
Cleaning environment and clean target, additionally the Straightway micro-water pump 26 of cleaning solution storeroom 11 lower end of water tank 2 both sides is all with general
Logical injector head 8 connects, and working speed keeps identical simultaneously, and the consumption well avoiding the cleaning solution due to both sides is uneven
The change of the position of centre of gravity of the unmanned plane 1 that weighing apparatus brings so that the control difficulty of unmanned plane 1 is strengthened by ground control system.
Along with the carrying out of cleaning, the clear water in reservoir chamber 10 and the cleaning solution in cleaning solution storeroom 11 are gradually disappeared
Consumption, when the water level of clear water is less than liquid level sensor 7 less than the liquid level of liquid level sensor 7 or cleaning solution, now liquid level data
Being transferred to earth station system through central control system by communication system, the people then controlling ground control system can operate nothing
Man-machine 1 landing, feed-tank 2 supplements clear water and cleaning solution, for being again carried out work.
When this system only operates at middle low level, it is jetted through the mixing liquid of clear water and cleaning solution at common injector head 8
After, water tank 2 water supply hose clamping device 4 below can make water supply hose 5 be connected with water tank 2 always, then micro-by direct current
Type water pump 1 stores clear water constantly to reservoir chamber 10, and the clear water making high-pressure injector head 9 always can eject high pressure is carried out clearly
Clean, clear water need not be supplemented because of reservoir chamber 10 and landing unmanned plane 1 repeatedly.
Above in association with accompanying drawing, the present invention is exemplarily described, it is clear that the present invention implements not by above-mentioned side
The restriction of formula, as long as have employed the improvement of the various unsubstantialities that method is conceived and technical scheme is carried out of the present invention；Or not
Improved, above-mentioned design and the technical scheme of the present invention are directly applied to other occasion, all in protection scope of the present invention
Within.
