Description

The optimum allocation method and system on a kind of networking unmanned plane reservation base station 5G charging level ground
Technical field
The invention belongs to UAV Intelligent charging schedule technical fields, and in particular to a kind of networking unmanned plane reservation base station 5G The optimum allocation method on charging level ground, the invention further relates to the systems for realizing the above method.
Background technique
Unmanned plane has flexibility high, and mobility is good, and reaction speed is fast, and operation requires low advantage, answers extensively For multiple fields such as logistics, security protection, aerial survey, inspection and agriculturals.Recently as country, to low latitude domain, open, unmanned plane is managed Etc. the appearance of relevant policies and the gradually mature hair for further having pushed unmanned plane industry and market of 5G mobile communication technology Exhibition.Unmanned plane usually needs to be implemented the task that far range is interior, time-consuming, but existing electronic multi-rotor unmanned aerial vehicle is usual Can only be non-stop flight about 1 hour, it is not able to satisfy round-the-clock, uninterrupted, AUTONOMOUS TASK the demand of unmanned plane.Although can be by taking Extend the unmanned plane utonomous working period with high capacity cell, but undoubtedly increase load in this way, reduces unmanned machine operation Efficiency, do not tackle the problem at its root.Unmanned plane can obtain energy resource supply nearby during AUTONOMOUS TASK, be to solve it The prefered method of energy deficiency problem in long-term autonomous operation process.Existing cellular mobile communication base station dense distribution and can To provide electric energy, just meet the demand condition of unmanned plane charging level ground arrangement, therefore can realize unmanned plane by base station Energy resource supply.
When unmanned plane is when needing to charge, multiple unmanned planes may be faced and compete the same charging level grounds or a unmanned plane Have multiple charging level grounds alternately the case where, how to realize at this time charging level ground reasonable distribution and it is optimal charging level ground selection be nothing A man-machine charging main problem to be solved.
Summary of the invention
The object of the present invention is to provide a kind of optimum allocation methods on networking unmanned plane reservation base station 5G charging level ground, solve nothing It is man-machine in the task of execution the problem of energy recharge.
It is a further object of the present invention to provide a kind of optimum allocation sides on above-mentioned networking unmanned plane reservation base station 5G charging level ground The system of method.
The technical scheme adopted by the invention is that a kind of optimum allocation side on networking unmanned plane reservation base station 5G charging level ground Method is specifically implemented according to the following steps:
Step 1, base station collect the current state on charging level ground, and simultaneously broadcast related information is then updated in constant duration; The unmanned plane driven into base station communication radius can obtain charging level ground situation, be sentenced according to the information such as self electric quantity and destination distance It is fixed whether to need to initiate charging reservation;
Step 2, when battery capacity is lower than charge threshold, unmanned plane is selected current location and is filled to available between destination Electric level ground;
Step 3 is obtaining and can calculate electricity consumed by unmanned plane to each charging level ground traveling with behind charging level ground;Synthesis is examined Consider the energy consumption for driving towards charging level ground, itself course information, remaining capacity, task emergency Multiple factors and carry out decision, realizes most Excellent charging level ground distribution;
Step 4, unmanned plane send reservation application to selected charging level ground, position including unmanned plane distance charging level ground, current Electricity and E.T.A;
Step 5, during unmanned plane drives towards selected charging level ground, decide whether to update its using the information newly obtained pre- About, if necessary to update, then new charging level ground is reserved again, otherwise continue former reservation platform charging;
Step 6, after charging complete, unmanned plane continues to execute its task.
Present invention is also characterized in that
In step 2: unmanned plane charge threshold is divided into 3 grades according to the number of remaining capacity, when unmanned plane remaining capacity is It is level-one low electric energy early warning shelves when 30%~40%;It is the low electric energy early warning shelves of second level when remaining capacity is 20%~30%;When It is three-level low electric energy early warning shelves when remaining capacity is 10%~20%;When multiple UAVs compete the same charging level ground, early warning There is the higher unmanned plane of series higher priority to charge.
In step 2: the number to be charged on the way according to unmanned plane current location, destination locations and unmanned plane, Being divided into the two kinds of situation selections that only need once to charge and need repeatedly to charge can be that S indicates present bit with charging level ground, detailed process It sets, D expression destination draws circle by radius of unmanned plane remaining capacity coverage R_1, be denoted as circle 1 using S as the center of circle;It is with D The center of circle justifies by radius work of maximum coverage R_2 of unmanned plane when fully charged, is denoted as circle 2;WhereinWithE in formulacFor unmanned plane current residual electricity, RmaxTotal electricity when being full of for battery, αevFly for unmanned plane The energy consumption of every meter of row;Alternately charge level ground set on the available charging level ground of overlapping region between two circles;When between circle 1 and circle 2 There is no overlapping region, unmanned plane, which needs to carry out repeatedly charging, can just arrive at the destination;Charging level ground selected by charging for the first time is One in multiple alternative charging level grounds in 1 coverage area of circle, the coverage area for being chosen at circle 2 on subsequent charge level ground is interior to be carried out Selection.
In step 3: influencing the factor and its weight calculation detailed process of decision are as follows: every meter in (a) unmanned plane driving process Energy consumption be αev, the energy consumption that unmanned plane reaches charging level ground is calculated according to the distance between unmanned plane and base station r, consume energy bigger weight It is smaller, it is denoted as w1=ε αevR, wherein ε is energy consumption weight coefficient;(b) according to unmanned plane destination and charging level ground position whether In same direction, if the two direction unanimously if set biggish weight, if the two is not in same direction, i.e. unmanned plane will be spent more Big cost charges, then sets lesser weight, be denoted as w2;(c) the more few then weight of unmanned plane remaining capacity is bigger, is denoted as w3;(d) significance level of unmanned plane execution task is higher, and weight is bigger, is denoted as w4;(e) according to w=w1+w2+w3+w4, w value gets over There is greatly higher priority to charge.
Another technical solution of the present invention is a kind of optimum allocation on networking unmanned plane reservation base station 5G charging level ground System, including multiple base stations 5G charging level ground and unmanned plane, each base station 5G charging level ground are equipped with one or more charging level ground data letters Cease processing module, be provided on unmanned plane the Position Fixing Navigation System being connected to the network mutually, Unmanned Aerial Vehicle Data message processing module with And charging guidance information release module, charge level ground processing data information module and Unmanned Aerial Vehicle Data message processing module and charging Guidance information issues data connection bootstrap algorithm and realizes module.
