Fig. 7 is second embodiment of the dust sensor Wiping mechanism in the utility model dust sensor self-induction mop system.Fig. 8 is along the cut-open view of C-C direction among Fig. 7.The difference of the dust sensor Wiping mechanism of this second embodiment and the dust sensor Wiping mechanism of first embodiment is that described light-passing board 3 is rectangle, the one side is provided with tooth bar 31, the front end of described motor drive shaft 61 is provided with gear 62, described tooth bar 31 and gear 62 are meshed, one side of described light-passing board 3 also is provided with the spring 7 that is used to make light-passing board 3 answers, so that make light-passing board 3 drive the to-and-fro movement of back do perpendicular to motor axis by motor 6.After wiping finished, spring 7 overcame rack-and-pinion and cooperates the resistance that is produced that light-passing board 3 is returned to initial position.Certainly, also can directly control positive and negative rotation of motor and get final product without spring 7.By revolution, rack-and-pinion cooperates makes light-passing board 3 do rectilinear motion, because polishing piece 2 is fixed, and therefore meeting relative motion between this moment light-passing board 3 and polishing piece 2, thus will wipe out attached to the dust of light-passing board 3 inner surfaces.
Fig. 9 is the 3rd embodiment of the dust sensor Wiping mechanism in the utility model dust sensor self-induction mop system.The difference of the dust sensor Wiping mechanism of the 3rd embodiment and the dust sensor Wiping mechanism of first embodiment is that described motor drive shaft 61 passes dust channel 12, all fixedly connected with the light-passing board 3 that is positioned at both sides, in order to drive described two light-passing boards 3 simultaneously, saved a motor.And described motor also can be replaced by the main motor of intelligent cleaning robot.
In addition, dust sensor Wiping mechanism in the utility model dust sensor self-induction mop system also can be matched with the motor drive shaft 61 of motor 6 with polishing piece 2, drive the back by motor 6 and do rotation or to-and-fro movement, and light-passing board 3 is arranged on corresponding fixed position.When revolution, make between light-passing board 3 and the polishing piece 2 and produce relative motion, thereby will wipe out attached to the dust of light-passing board 3 inner surfaces.
Below, in conjunction with Figure 10 to Figure 13 the determination methods of the utility model dust sensor light-passing board pollution level is described.
The real signal value curve of Figure 10 for receiving by the dust sensor among Figure 13, the transverse axis express time of Figure 10 (unit is " second "), longitudinal axis Y are represented dust sensor real signal value (unit is " millivolt ").
The real signal value curve that dust sensor receives is subjected to the influence of two aspects, is the influence from ground amount of dust on the one hand, and it fluctuates up and down at random, and on macroscopic view, it does not produce regular variation in time; Be the influence of polluting from light-passing board on the other hand, it clocklike changes in time, and the time is long more, and pollution level increases.Therefore, integrate, described real signal value curve is localised waving and overall downward trend.
After the interchange variable quantity of the actual signal that the hardware circuit by as shown in figure 13 receives dust sensor amplifies, obtain variation value curve as shown in figure 11, the transverse axis express time of Figure 11 (unit is " second "), longitudinal axis Y1 are represented the variation value (unit is " millivolt ") of dust sensor signal.Under the normal condition, described variation value curve is fluctuation up and down within the specific limits, reflects that each enters into the situation of change of the amount of dust of intelligent cleaning robot dust channel constantly, promptly, reflect indirectly and can the amount of dust on ground in time be detected what of floor-dust amount by means of this numerical value.Signal intensity after the processing and amplifying, the situation that can observe real signal value more clear, effectively, thus the work of purging system is controlled in the variation in the short time according to described variation value curve.
On the other hand, the actual signal that hardware circuit by as shown in figure 13 receives dust sensor is after the A/D conversion, ask arithmetic mean to handle, obtain mean value curve as shown in figure 12, the transverse axis express time of Figure 12 (unit is " second "), longitudinal axis Y2 are represented the mean value (unit is " millivolt ") of dust sensor signal.Described mean value curve is downward trend gradually, reflects that light-passing board is polluted gradually, its gradually downtrending the size mainly determine by the pollution level of light-passing board.Y2 is more little for arithmetic mean, and the pollution level of dust sensor light-passing board is serious more.Control wiping by means of described mean value curve result of variations in a long time to light-passing board.
That is, if arithmetic mean Y2 during less than a certain preset value, it is many then to judge the accompanying dust of dust sensor light-passing board, and the light-passing board pollution level is big, and light-passing board needs wiping.Described preset value can be set according to actual needs, and normally the empirical value that draws by test of the producer is stored in the corresponding memory in advance.
Below, in conjunction with Figure 14 the course of work of the utility model dust sensor self-induction mop system is described.
After the intelligent cleaning robot started working, the amount of dust in the 1 pair of dust channel 12 of dust sensor in the utility model dust sensor self-induction mop system was carried out acquisition of signal, obtains real signal value (step S1).
The interchange variable quantity of the real signal value that dust sensor is received amplifies, and carries out the A/D conversion, obtains the variation value (step S2) of dust sensor signal, and this value is transfused to control module 201 (microcontroller (MCU)).
When the variation value of dust sensor signal during greater than first preset value (being "Yes" in step S3), the amount of dust of then thinking dust sensor and being detected is big, needs to carry out fixed point cleaning action.At this moment, control module 201 sends 401 pairs of ground of instruction startup cleaning agency and fixes a point to clean (step S4).Described first preset value can be set according to actual needs, and normally the empirical value that draws by test of the producer is stored in the storer of control module in advance.
After meanwhile the real signal value that dust sensor is received carried out the A/D conversion, Input Control Element 201 (microcontroller (MCU)) asked arithmetic mean to handle, and obtains the mean value (step S5) of dust sensor signal.
When the mean value of dust sensor signal during less than second preset value (being "Yes" in step S6), think that then the accompanying dust of dust sensor light-passing board 3 is many, the light-passing board pollution level is big, needs to carry out wiping action.At this moment, control module 201 sends and instructs 301 pairs of dust sensor light-passing boards of startup dust sensor Wiping mechanism 3 to carry out wiping (step S7).Described second preset value also can be set according to actual needs, and is stored in advance in the storer of control module.
In addition, the utility model dust sensor self-induction mop system can be determined the length of wiping time according to the order of severity that the dust sensor light-passing board pollutes.For example can set two threshold values (first threshold is greater than second threshold value), when Y2 value (arithmetic mean) during less than first threshold and greater than second threshold values, Wiping mechanism begins wiping, and the wiping time was shorter, as wiping 2 seconds; When Y2 value during less than second threshold value, pollution grows worse can prolong the wiping time, as wiping 5 seconds.The described first threshold and second threshold value also are to set according to actual needs, are stored in the corresponding memory in advance respectively.
In addition, the dust sensor output terminal can be looked by the intelligent cleaning robot in the process of any sweeper mode output situation determines whether carrying out the wiping and the length of wiping time of dust sensor light-passing board." carrying out the fixed point cleaning moves " and " execution wiping action " can carry out synchronously, also can be when " execution wiping action ", and the intelligent cleaning robot temporarily stops " carrying out fixed point cleaning action ".In fact, in the use of intelligent cleaning robot, because the time of dust is very short on the wiping dust sensor light-passing board, in the chronomere of level second, can finish wiping work, so " fixed point cleaning action " and " action of wiping dust sensor light-passing board " are to carry out synchronously, still separately carry out, to robot work itself, without any influence.
After wiping action is finished, turn back to step S 1, and the mean value of the actual signal that receives according to current dust sensor judges whether needs wiping once more.Wiping action (step S7) is then carried out in wiping once more if desired once more.
