Specific embodiment
Technical solution provided by the present invention is made a detailed description below by way of the drawings and specific embodiments:
As shown in Figure 1, it is the knot in the wherein air duct that the dust-full detection system of sweeping robot of the present invention is related toStructure schematic diagram.The air duct be horizontal air duct, be disposed in the horizontal plane air inlet 101, dust-collecting box 102, strainer 103,The air outlet 105 of dust sucting motor 104 and dust sucting motor.As shown in Fig. 2, being the dust-full detection system of sweeping robot of the present inventionThe structural schematic diagram in the another air duct that system is related to.The air duct is rectilinear air duct, and air inlet is disposed on vertical plane201, the air outlet 205 of dust-collecting box 202, strainer 203, dust sucting motor 204 and dust sucting motor.Arrow in Fig. 1 and Fig. 2 is indicatedFlow direction of the air in the air duct.
By taking the air channel structure in Fig. 1 as an example, the principle of the present invention is illustrated.It is empty under the action of dust sucting motor 104Gas enters air duct by air inlet 101, successively passes through dust-collecting box 102 and strainer 103, and air duct finally is discharged by air outlet 105.In windIn each component part in road, any portion blocking, such as the blocking of air inlet 101 or strainer 103 are blocked, and can all lead to entire air ductBlocking.Since during dust suction, most dusts can be trapped in dust-collecting box 102 by strainer 103, so air outlet 105Seldom cause blockages, and relatively common blockage problem is mainly blocked up by air inlet 101, dust-collecting box 102 and strainer 103Caused by plug.
When air inlet 101 blocks, reason may be that sweeping robot enters some special ground regions, such asIt is laid with the region of carpet, carpet fold under the action of suction is picked up to air inlet 101, sweeping robot is caused to walkDifficulty, air duct blocking.In this case, the walking resistance of sweeping robot greatly increases, adjoint to be in the presence of it being walking electricityThe electric current of machine increases；In the case where opened loop control, the revolving speed of movable motor be will also decrease；In the case where closed-loop control, walking electricityThe revolving speed of machine remains unchanged, but the electric current of movable motor is by the more obvious of increase.If air duct obstruction is strictly by above-mentioned originalBecause caused by, at this point, reducing the input parameter of dust sucting motor 104, reduces the suction of sweeping robot, will be helpful to carpet in this wayIt is detached from air inlet 101, so that sweeping robot be helped to restore automatically to the state of normal walking, what air inlet 101 blocked is askedTopic will also be eliminated therewith, be not necessarily to manual intervention.And if reducing the input parameter of dust sucting motor, it is even switched off dust sucting motor, allThe electric current of movable motor, revolving speed can not be made to restore normal, then illustrate that failure occurs in sweeping robot, need to remind user to sweepingFloor-washing robot is checked, with debugging.In the situation that air inlet 101 blocks, user need not be specially to dust-collecting box 102It is operated.
And when air duct blocks, either since the blocking of air inlet 101, dust-collecting box 102 are filled blocking or strainer103 block, and the air quantity in entire air duct will reduce, therefore the load of dust sucting motor 104 will become smaller.According to motorWorking mechanism, the electric current of dust sucting motor 104 can decline at this time, and the wind speed of air outlet 105 can reduce；Meanwhile if dust sucting motor104 be opened loop control, then the revolving speed of dust sucting motor 104 will also rise；If dust sucting motor 104 is closed-loop control, dust suction electricityThe revolving speed of machine 104 will remain unchanged, but becoming apparent of can declining of the electric current of dust sucting motor 104.In this case, if in conjunction withTo the judging result of movable motor electric current and/or revolving speed, the situation of the blocking of air inlet 101 is eliminated, then can determine air ductBlocking is since dust-collecting box 102 is filled or strainer 103 occurs caused by blocking.But regardless of being that dust-collecting box 102 is filled, alsoIt is that strainer 103 blocks, it is necessary to remind user dust-collecting box 102 to be handled or toppled over the rubbish in dust-collecting box 102Rubbish or replacement or cleaning strainer 103, can make air duct restore unobstructed.
Based on the above principles, machine of sweeping the floor can be first determined whether by way of detection movable motor electric current and/or revolving speedWhether people breaks down or whether air inlet 101 blocks；According to the judging result to movable motor, by above situation plusAfter excluding, then the reason of blocking is judged by way of detecting 104 electric current of dust sucting motor, 105 wind speed of revolving speed and/or air outletWhether occur on dust-collecting box 102 or strainer 103, to further user be reminded to operate dust-collecting box 102.Moreover, adoptingUser is reminded to clear up dust-collecting box 102 with technical solution of the present invention, other dust-full detection means, example compared to this fieldSuch as weight detecting, photosensitive detection mode have valence without the expensive all kinds of high-performance sensors sensors of additional setting valueLattice advantage.Meanwhile technical solution of the present invention also has higher compared to traditional detections modes such as weight detecting, photosensitive detectionsStability and veracity because density, the humidity difference of rubbish cause weight detecting to be difficult accurately to reflect dust-collecting boxWhether 102 be already filled up；And light-sensitive element, in use due to the absorption of dust and accumulation, surface is easily overwritten,So as to cause erroneous judgement.
As shown in figure 3, being the function structure chart of the dust-full detection system first embodiment of sweeping robot of the present invention.It shouldFirst embodiment includes: first detection module 301, obtains the first parameter, the movable motor of the sweeping robot for detecting307 be opened loop control when, first parameter include the sweeping robot movable motor 307 the first electric current and/or first turnSpeed；When the movable motor 307 of the sweeping robot is closed-loop control, which includes the sweeping robot walking electricityFirst electric current of machine 307；
