Description
Technical field
the utility model relates to a kind of micro computer mouse spurt control system, particularly relates to the very fast company of a kind of two-wheeled micro computer mouse double-core controller and turns spurt servo-drive system.
Background technology
micro computer mouse is a kind of Intelligent walking robot that uses embedded microcontroller, sensor and electromechanical movement parts to form, micro computer mouse can be in different " labyrinths " automatic Memory and selecting paths, adopt corresponding algorithm, arrive rapidly the destination setting.The match of micro computer mouse has had the history of more than 30 years abroad, all will hold in the world every year now up to a hundred similarly micro computer mouse contests.
the contest of micro computer mouse adopts working time, labyrinth time and touches this three parameters, mark from three aspects of reliability of speed, the efficiency that solves labyrinth and computer mouse, different countries adopts different standards of grading, has four national standards of representative to be most:
the U.S.: the international micro computer mouse of IEEE APEC robot competition, exploration time, spurt time and the fixing deduction of points that contacts, all charge to overall scores, score=exploration time/30+spurt time+fixing contact deduction of points;
japan: the international micro computer mouse robot conference in all Japan (expert's level), overall scores only calculates the spurt time, score=best spurt time;
britain: the challenge match of micro computer mouse robot, overall scores is all charged in exploration time, spurt time and the variable deduction of points that contacts, score=exploration time/30+spurt time+variation contact deduction of points;
singapore: robot contest, exploration time, spurt time are charged to overall scores; Each robot that contacts once attempts chance by minimizing, score=exploration time/30+spurt time.
from international standard above, the success or failure of spurt Time dependent whole micro computer mouse, because the unit of this robot of domestic research and development is less, R & D Level is relatively backward relatively, the micro computer mouse structure of research and development is as Fig. 1, and long-play is found to exist a lot of safety problems, that is:
(1) what adopt as the eyes of micro computer mouse is ultrasound wave or general infrared sensor, and sensor arrange wrong, make micro computer mouse in the time of quick spurt to around the judgement in labyrinth there is certain erroneous judgement, make micro computer in spurt fast, easily knock the barricade in front.
(2) what adopt as the topworks of micro computer mouse is stepper motor, and the problem that often can run into pulse-losing occurs, causes the memory of spurt position to occur mistake, can not find sometimes the terminal of spurt.
(3) owing to adopting stepper motor, make organism fever more serious, be unfavorable for spurt fast in large complicated labyrinth.
(4) owing to adopting more rudimentary algorithm, make the calculating in best labyrinth and the calculating in spurt path have certain problem, the micro computer mouse of research and development can repeatedly not accelerate spurt substantially automatically, spurt in the middle of general labyrinth generally all will spend the time of 15 ~ 30 seconds, and this makes cannot win victory in real international complex maze contest.
(5) because micro computer mouse is needing brake frequently and start in spurt process fast, increased the weight of the workload of single-chip microcomputer, Signal Processors cannot meet the requirement of spurt fast of micro computer mouse.
(6) what relatively adopt is all that the plug-in components that some volume ratios are larger makes the volume and weight of micro computer mouse huger, and center of gravity is higher, cannot meet the requirement of quick spurt.
(7) owing to disturbed by surrounding environment labile factor, the particularly interference of some light around, singlechip controller often there will be extremely, causes that micro computer mouse is out of control, and antijamming capability is poor.
(8) for the micro computer mouse of differential control, it is synchronous that the control signal of two motor of General Requirements is wanted, but be difficult to accomplish for single single-chip microcomputer, make micro computer mouse can be in the middle of labyrinth in the time of sound lunge rocking tendency larger, often occur that the phenomenon of hitting wall occurs, and causes making a spurt unsuccessfully.
(9) owing to being subject to single-chip microcomputer capacity and algorithm affects, micro computer mouse is not stored the information in labyrinth, and information all in the time running into power-down conditions will disappear, and this cannot complete whole spurt process.
(10) owing to not having the auxiliary of angular-rate sensor to turn, often occur that the too small or excessive phenomenon of angle of turn occurs, then rely on the sensor of navigation to compensate, in the labyrinth that causes turning in continuous several times, occur that the phenomenon of hitting wall occurs, and causes and makes a spurt unsuccessfully.
(11) adopt single-sensor to find out the barricade in labyrinth, front, very easily receive external interference, cause the upfront sensor misguidance micro computer mouse of spurt fast, cause micro computer mouse in labyrinth, make a spurt not in place or hit wall, cause and make a spurt unsuccessfully.
therefore, need to redesign based on monolithic processor controlled micro computer mouse controller existing.
