Specific embodiment
The invention proposes a kind of comprehensive radio frequency system working method decision-making techniques of unmanned platform.This method is based on decision branch
Hold system (DSS) thought, using knowledge base, database, model library, man-machine interactively structure composed, research work mode is autonomous
Discrimination model design, realizes light-type, high real-time, the decision support function for meeting job task demand.Function of the invention
Framework includes five functional unit as shown in Figure 1, be wherein decision-making software in dotted line frame:
(1) target and environmental knowledge library
Object knowledge library includes radiant source target Characteristics of Electromagnetic, objective attribute target attribute, model, Platform dynamics type, puts down
The information such as platform mechanical movement velocity interval, activity space range.Environmental knowledge library includes longitude and latitude, height, administrative area under one's jurisdiction, military affairs
The information such as goal activities section, civilian site activity interval.
(2) real-time data base
1) this platform detection data: radar active target point mark, track, target identification including real-time update are as a result, spoke
Penetrate Source Description digital data (EDW)；
2) other platform detection datas: unmanned platform is generally configured with wireless communication function, and support data is shared and cooperateed with
Work, using cooperating, the data obtained can increase information content and information dimension.By cooperateing with channel, this unmanned platform can
To share target information with other platforms, cotasking request can also be initiated/received mutually.
3) target information storage pretreatment: the fresh target that will be seen that classified, matched, symbolism, storage.
(3) model and rule base
1) air threat priority model: the additional Threat generated comprising target Threat itself and other objective cross, meter
Calculate formula:
Di=aFi+b·Qi (1)
Di: the Threat of i-th of target, i=1,2 ..., N.N is total target lot number.
Fi: the Threat being calculated by i-th of target inherent parameters.
Qi: the additional Threat of i-th of target of imparting generated by other targets of same batch.
A, b are the weight coefficient for threatening item.
2) task model: specific tasks type is designed according to the functional requirement of comprehensive radio frequency system, each task includes one
A opposite execution priority parameter, the models of priority of each task is designed according to operating rule.The comprehensive radio frequency system of unmanned platform
Executable main task type includes: passive search, passive tracking, collaboration passive location, electromagnetic interference/trick, communication, master
Dynamic search, active tracing, active target identification etc..
3) task triggering rule: information fusion is carried out according to real time data, the model of different tasks is generated according to result.
Such as when the radiant source target Threat of intercepting and capturing reaches certain rank, determine to generate co-located task for emphasis radiation source；When not
When having cooperation condition, passive guidance active tracing task is generated.
4) task priority model: according to the functional parameter of the detection environment of comprehensive radio frequency system and object, design, design
Comprehensive radio frequency system task priority parameter model.Task priority model inclusion region priority, air threat priority, task class
Type priority, task deadline four elements.Design objective comprehensive priority is linear function:
Pj=w1Xj+w2Dj+w3Aj+w4DTj (2)
Meaning of parameters:
Pj: the priority of j-th of target, j=1,2 ..., M, M >=N.M is total task number.
Xj: the task type priority serial number of j-th of task.By by M task according to task priority from high to low
Arrangement obtains sequence X.
Dj: the air threat priority serial number of j-th of task.It is obtained by arranging M task from high to low according to Threat
Sequence D.
Aj: the corresponding monitoring airspace priority serial number of j-th of task.By by M task according to airspace importance from height
Sequence A is obtained to low arrangement.
DTj: the off period priority number of j-th of task.It is obtained by arranging M task from small to large according to the off period
Sequence obtains sequence D T.
w1, w2, w3, w4: for the weight coefficient of priority factors.It can be according to the mission and operating environment of comprehensive radio frequency system
Dynamic adjusts.
5) typical working method, each working method packet working method model: are designed according to comprehensive radio frequency system mission
Containing certain set of tasks, there are intersections between set of tasks, but each working method can be distinguished according to some feature.
This task-set and feature constitute working method model.This method is using exclusive significant task type as working method area
Other feature.
6) the autonomous decision rule of working method: according to unmanned platform application environment, using rule designed by working method
Between switch condition.By the task type of highest priority in task-set 1 decision parameter the most in this method, when it and certain work
Make to be converted to the working method when the significant task type under mode is consistent.
7) working method decision error alarm triggering rule: when manual intervention order is different from current autonomous court verdict
When, alarm is provided, and prompt current court verdict, current high threat target information.
8) manual decision and the selection principle made decisions on one's own: preferential to execute artificial do when receiving manual intervention order
Otherwise pre-command executes autonomous court verdict.
(5) inference engine unit
Measured data and target information storehouse matching are compared, binding model and rule make inferences calculating, calculate and threaten
Two degree, task priority parameters complete 2 judgements, obtain the autonomous court verdict of working method.
Judgement 1: being based on air threat priority calculated result, and task-set 1 is generated in the case where task trigger gauge then drives；
Judgement 2: it is autonomous to generate working method under the autonomous decision rule of working method for task based access control priority calculated result
Court verdict；
(6) man-machine interactively unit
There are target information coffrets, manual control command interface between decision-making software and higher level command and control center.
By the interface, person on duty assigns manual intervention order to decision-making software, and decision-making software is sent out according to the result of judgement 3 to person on duty
Warning prompt, working method confirmation message out.After decision-making software receives manual confirmation result, the working method of manual confirmation is selected
As the final result of decision.
Judgement 3: computer is directly executed when decision-making software does not receive manual control order and is made decisions on one's own result；When connecing
Receive with computer make decisions on one's own result identical working method intervention command when, execute the result；When different, give a warning
Prompt, and ask whether to execute the working method intervention command.
