Background technology
Firefighting robot is that in one, in simulating reality life, the mankind find harmful burning things which may cause a fire disaster and can a kind of Intelligent Robot of automatic distinguishing burning things which may cause a fire disaster.Generally, match type firefighting robot can move in a planar structure house model, finds a candle representing burning things which may cause a fire disaster and it extinguished under working rule instructs with the shortest time.The process of robot process fire alarm in simulating reality family.Candle represents the burning things which may cause a fire disaster that family is lighted, and robot must find and extinguish burning things which may cause a fire disaster.The bottom of candle flame is by overhead 15-20cm is high.Candle is the Chinese wax candle of diameter 1-2cm.The exact height of candle flame and size are uncertain, changes, and are determined by the environment of candle condition and surrounding.Candle will be placed in a room of competition area randomly, regardless of flame specifically what size after match starts, all requires that robot can find candle.
In real match, in order to strengthen competition difficulty, competition area are divided into the mode standard of n*n lattice, and what the most often adopt is the uniform pattern of 8*8 lattice, and its competition area structure as shown in Figure 1, will find burning things which may cause a fire disaster and extinguish in 64 lattice rooms by firefighting robot.Search in burning things which may cause a fire disaster map in the two dimension of Fig. 1, the material of wall is wooden general and can be reflective, and the length of every block barricade is that 60cm is long, and height is at 27-34cm.Ground, competition area is smooth, and the floor in place is black.Black is all brushed in any gap on place.The gap in place is no more than 5mm.Some robots may use foam, and powder or other material carry out the flame of extinguishing candles.Because after the match of each robot, the quality in cleaning place directly has influence on surface state, face, old place does not ensure all to keep absolute black during the games whole.Once start, firefighting robot oneself must control navigation under the intervention of nobody, but not manual control, searching the stability in burning things which may cause a fire disaster process to test firefighting robot, it cannot collide or contact wall, otherwise will be caught a packet.
A complete firefighting robot is roughly divided into following components:
1) motor: actuating motor is the power source of firefighting robot, it performs according to the instruction of microprocessor the relevant action that firefighting robot walks on two dimensional surface;
2) algorithm: algorithm is the soul of firefighting robot, firefighting robot must adopt certain intelligent algorithm could arrive the motion in another one room quickly and accurately from a room, then find burning things which may cause a fire disaster, and open self-contained dry ice controller, put out burning things which may cause a fire disaster;
3) microprocessor: microprocessor is the core of firefighting robot, be the brain of firefighting robot, the information that firefighting robot is all, comprises room wall information, fire location information, and motor status information etc. all needs through microprocessor processes and makes corresponding judgement.
Firefighting robot combines multi-subject knowledge, for promoting the manipulative ability of students, team collaboration's ability and innovation ability, promotes that the scope of one's knowledge of the digestion of student classroom knowledge and expansion student is all very helpful.The unit of domestic this robot of research and development is more, but the robot of research and development is relatively backward, and the firefighting robot structure of research and development is as Fig. 2, and long-play finds to there is a lot of safety problem, that is:
(1) mostly what adopt as the topworks of firefighting robot is stepper motor, often can run into pulse-losing causes motor desynchronizing phenomenon to occur, cause occurring mistake to the memory of position, firefighting robot cannot seek burning things which may cause a fire disaster, or after fire extinguishing, starting point cannot be got back to by robot;
(2) owing to adopting stepper motor, make organism fever relatively more serious, need sometimes to carry out installing heat abstractor additional, robot overall weight is increased;
(3) owing to adopting stepper motor, the occasion that system is generally not suitable for speed is higher is run, and easily produces vibration, sometimes may contact wall during high-speed motion, causes finding burning things which may cause a fire disaster failure;
(4) because firefighting robot will brake frequently and start, increased the weight of the workload of single-chip microcomputer, single single-chip microcomputer cannot meet the requirement that firefighting robot starts fast and stops;
(5) what relatively adopt is all the plug-in components that some volume ratios are larger, and make firefighting robot control system take larger space, weight is relatively all heavier;
(6) owing to disturbing by surrounding environment labile factor, singlechip controller often there will be exception, and cause firefighting robot out of control, antijamming capability is poor;
(7) burning things which may cause a fire disaster process is found for two-wheeled firefighting robot, the pwm control signal of two motor of General Requirements wants synchronous, due to the restriction by single-chip microcomputer computing power, single single-chip microcomputer servo-drive system is difficult to meet this condition, firefighting robot walking navigation is made to be difficult to control, particularly for worse off cake when walking fast;
(8) owing to adopting two power wheels to drive, acceleration during in order to meet fast searching burning things which may cause a fire disaster and deceleration, make the power of single drive motor larger, the space not only taken is larger, and under the state that some relative requirements energy are lower, sometimes cause the phenomenon of " low load with strong power " to occur, be unfavorable for the saving of the firefighting robot system energy;
(9) based on the firefighting robot that monokaryon controls, particularly for the firefighting robot that many wheels control, because the algorithm of single core processor process is more, arithmetic speed is not very fast, is unfavorable for that robot runs up;
(10) in actual fire extinguishing procedure, burning things which may cause a fire disaster may not be in room center of a lattice, and causing has an angle between the direction of travel of firefighting robot and burning things which may cause a fire disaster, causes putting out a fire and has consumed a large amount of dry ice, sometimes may extinguish burning things which may cause a fire disaster;
(11) in actual fire extinguishing procedure, due to the burning of candle, it is highly also changing, and the burning things which may cause a fire disaster in this and reality is also closely similar, but the nozzle height of the dry-ice fire extinguisher that general firefighting robot carries is fixing, cause effectively to put out burning things which may cause a fire disaster;
(12) in actual fire extinguishing procedure, common light source acquisition sensor can may receive the interference of external light source, causes fire extinguishing to seek failure, cannot finish the work.
Therefore, need to redesign based on monolithic processor controlled two-wheeled firefighting robot controller existing, seek a kind of economic and practical can use in reality six take turns double-core full-automatic fire-extinguishing machine people servo-drive system.
