Have simple to operate, spray uniformly, dosage is few, efficiency is high, be easy to the features such as information system management.
Current plant protection unmanned plane, when spraying insecticide, needs the flight effector of specialty to manipulate, and by
Being uneven in ground, farmland causes crops the most inconsistent, needs effector to adjust throttle and makes unmanned
The machine height away from crops keeps consistent, thus reaches the uniform requirement of herbal sprinkling.Flight effector is behaviour
In control unmanned plane operation process, only control the amplitude of throttle by range estimation, this technology requirement to professional
The highest, control accuracy is low, unmanned plane also cannot be made to be used widely simultaneously.
Chinese patent CN201520139322.4 is it is proposed that one excessively is controlled fixed based on plant protection unmanned plane ultrasound wave
High operating system, its operation principle is to measure the unmanned plane altitude information away from ground by ultrasonic detector,
It is transported to monitor by Video Character Superpose and provides judgement to operator.Its signal and receiver signal are simultaneously
In access single-chip microcomputer, Single-chip Controlling make a decision output signal, the instruction of the height that interior setting is variable, and
Fixed high open command is also performed, finally by single-chip microcomputer all height by remote controller accessory channel switch
Signal is supplied to flight control system, flight control system regulate power, it is achieved the ultrasound wave of plant protection unmanned plane is controlled fixed
High so that plant protection unmanned plane realizes self regulation and can realize controllable height.
Such scheme is the fixed high system of a set of ultrasound wave that adds outside the fixed high system of GPS of unmanned plane, though
Existing plant protection unmanned plane so can be overcome cannot automatically to determine high defect, but it is difficult to use ultrasound wave to determine high-tech
Degree is relatively big, device structure is more complicated, needs to install single-chip microcomputer, receiver, ultrasonic listening on unmanned plane
The various electronic such as device, realizing of whole platform is relatively costly, and owing to equipment is various, ultrasound
Away from algorithm the most complex, stability and the efficiency of the work of the fixed high system of this ultrasound wave there is also doubtful
Ask.
Utility model content
In order to solve the problems referred to above, applicant, through Improvement, now provides the fixed height of auxiliary of a kind of unmanned plane

The fixed high system of auxiliary in embodiment illustrated in fig. 1 includes the flexible strip-the first that two length is different
Flexible strip 5-1 and the second flexible strip 5-2, two induced signal emitter the-the first induced signals are sent out
Emitter 6-1 and the second induced signal emitter 6-2,7, main control module 8 of an induced signal receptor
And a flight control system 4.First flexible strip 5-1, the second flexible strip 5-2 can be rubber,
Fabric, the hollow pipe soft excellent, soft of plastic material or soft ribbons structure, its adjustable length is the most detachable, both
One end be connected to the lower section of two different support arms 2 of rotor wing unmanned aerial vehicle.First induced signal is sent out
Emitter 6-1 and the second induced signal emitter 6-2 are separately mounted to the first flexible strip 5-1 and second soft
The other end of property bars 5-2.In other embodiments, it is possible to by the first flexible strip 5-1 and second
Flexible strip 5-2 is arranged on the lower section of same support arm 2；Or can also be only with a flexible barcode
Part, and the first induced signal emitter 6-1 and the second induced signal emitter 6-2 is separately positioned on same
Differing heights position on bar flexible strip, is arranged one on the other.Induced signal receptor 7, master control mould
Block 8, flight control system 4 are arranged on above fuselage 1 or inside, in the embodiment given by this utility model
It is mounted in the inside of fuselage 1.
Flight control system 4, induced signal receptor 7, main control module 8 are in FIG owing to being mounted in fuselage 1
Inside, invisible at aircraft exterior, its circuit connecting relation is shown in Fig. 2.
Refer to Fig. 2, the first induced signal emitter 6-1, the second induced signal emitter 6-2 and sensing
By wired or wireless connections between signal receiver 7, main control module 8 and induced signal receptor 7,

The work of system 3.
Referring to Fig. 3～Fig. 5, as a example by this utility model application on plant protection unmanned plane, this practicality is new
The fixed high principle of type is as follows:
If being used as fog machine by this utility model, in fuselage 1 inside or lower section, medicine-chest need to be installed,
Dosing mouth, flusher are set on medicine-chest.
First, according to different vegetation, the dispenser requirement for height of different agents, by the first flexible strip 5-1
With the second flexible strip 5-2, length being adjusted to L1 and L2 (L1 > L2) respectively, the dispenser making regulation is high
Degree is between L1 and L2.
First induced signal emitter 6-1, the second induced signal emitter 6-2 are to contact with object or connect
Send signal during nearly distance (such as 1cm) to a certain setting, do not send out when not touching or proximating to object
Go out the device of signal.
In Fig. 3 state, the first induced signal emitter 6-1 touches vegetation, and the second induced signal is launched
Device 6-2 is not in contact with to vegetation.Therefore, induced signal receptor 7 receives the first induced signal emitter 6-1
The signal sent, and do not receive the signal that the second induced signal emitter 6-2 sends.Induced signal receives
This signal is delivered to main control module 8 by device 7, main control module 8 by preset program learn now unmanned plane away from
From the flying height of vegetation top end surface between L1 and L2, this highly meets requirement, this fog machine height
Remain unchanged, dispenser can be carried out.
In Fig. 4 state, the first induced signal emitter 6-1, the second induced signal emitter 6-2 all contact
Arrive vegetation.Therefore, induced signal receptor 7 receives the first induced signal emitter 6-1 and second sense
The signal that induction signal emitter 6-2 sends.This signal is delivered to main control module 8 by induced signal receptor 7,
Main control module 8 learns that by preset program the flying height of the distance vegetation top end surface of now unmanned plane is less than
L2, the most too low, thus the multiple output channels controlling flight control system 4 control each rotor power system 3
Work, promotes the flying height of this fog machine, until Fig. 3 state.
In Fig. 5 state, the first induced signal emitter 6-1, the second induced signal emitter 6-2 all do not connect
Contact vegetation.Therefore, induced signal receptor 7 do not receive the first induced signal emitter 6-1, second
What induced signal emitter 6-2 sent touches signal.Induced signal receptor 7 now no signal delivers to master control
Module 8, main control module 8 learns the flight of the distance vegetation top end surface of now unmanned plane by preset program
Highly more than L1, excessive height, thus the multiple output channels controlling flight control system 4 control each rotor power
The work of system 3, reduces the flying height of this fog machine, until Fig. 3 state.
Above-described is only preferred implementation of the present utility model, and this utility model is not limited to above enforcement
Example.It is appreciated that those skilled in the art are straight on the premise of without departing from spirit of the present utility model and design
Connect and derive or the oher improvements and changes associated, be all considered as being included in protection domain of the present utility model it
In.
