Belong near infrared band.Correspondingly, the laser of other wavelength of near infrared band also has preferable relative to other wave band of laser
Effect.
The principle of laser cleaning is emitted due to acoustooptical effect to surrounding when paint film absorbs laser and heated by alternation
Sound wave, photic acoustic wave energy are a part of laser energy.In the photic sound wave that surface of the paint film generates, it is equivalent to a sound wave
Source launches outward sound wave.Sound wave into paint film reflects again after reaching the body surface under paint film, the sound so generated
Wave has biggish amplitude and good coherence, so reflected acoustic wave and incident acoustic wave will interfere, thus makes
The vibration in place exponentially increases, and like producing the explosion of micro- power in paint film, paint is become extremely small dust and clear
It removes.
In the structure shown in Fig. 1 ~ 3, the laser cleaner of sports field markings needs to configure a carrier, base
In the principles of the present invention, which reduces the factor of manpower intervention, can realize automatic control as far as possible.
The preferred wheel undercarriage in chassis is that sports field operating condition is relatively good, and wheel undercarriage control is more flexible, and energy consumption
It is relatively low.Also it is not excluded for the use on other types chassis, such as caterpillar chassis, caterpillar chassis is relatively steady, braking
Can be relatively good, but speed is relatively slow.
In contrast, in the embodiments of the present invention, the required precision that chassis is advanced is not high, and has not also required
Relatively reliable at the uniform velocity performance, especially sports field is generally relatively flat, and for chassis, direction controlling is even more important.
The markings of sports field are generally closed line, such as track line, include straightway and arcuate line segment group on the whole
It is made into an annular, suitable for working continuously.
Part of the chassis for bearing article is commonly referred to as support plate 2, such as flatcar, trolley, straddle carrier, bearing part are
Table top, table top are provided by the plate being located on running gear, and plate is referred to here as support plate 2.
Since the output par, c for the component being loaded on support plate 2 is mounted on the lower surface of support plate 2 more, such as vacuum part and swash
Light device part, to reduce assembly difficulty, 2 front of support plate is equipped with the first pilot hole, and middle part is equipped with the second pilot hole, thus, such as
Vacuum part, main part are located on the table top of support plate 2, and its suction inlet 10 is then located at the lower surface of support plate 2.
Accordingly for laser, the main body of the laser is mounted on chassis, and the fixed peace of laser head 11 of laser
Mounted in the first pilot hole, making laser head 11, laser head 11 is mainly including exit lens 15 and for installing exit lens 15 downwards
Mechanical part.
In use, chassis is across on blip line, the lower surface of the support plate 2 on chassis is substantially parallel with blip line,
The axis of exit lens 15 is accordingly vertical with ground or blip line.
About dust catcher, as previously mentioned, its main part is mounted on chassis, it is specifically mounted in the support plate 2 on chassis
On table top, suction inlet 10 is by the second pilot hole row in 2 bottom of support plate, it is to be understood that before suction inlet 10 is for drawing
11 the formed crushed material of clear flag line of side laser head, suction inlet 10 should be greater than being equal to target in the lateral array-width of support plate 2
The width of markings.
It is understood that the array-width of suction inlet 10 is also not easy excessive, unnecessary waste otherwise can be generated.
For the tracking of markings, photoelectric sensor group is provided, 9 row of multiple photoelectric sensors being adapted to is before chassis
End, specifically, can be the front underside of support plate 2, is also possible to the front end face of support plate 2.
About photoelectric sensor 9, active photoelectric sensor can also be, be also possible to passive type photoelectric sensor, it is main
Dynamic formula photoelectric sensor is sampled by being transmitted to the light of standing wave section based on the reflected light projected on object.For passive
Formula photoelectric sensor then depends on the natural light under external light source, such as daylight condition.
It is understood that not only body color reflectivity is high for markings, but also its surface is opposed flattened, diffusing reflection effect
It is weaker, and for runway face, it is that such as color asphalt concrete paves and is formed by surface, rough surface, diffusing reflection effect is non-
Chang Qiang, the two have very big difference to the reflecting effect of light.In contrast, either active photoelectric sensor or quilt
Dynamic formula photoelectric sensor, can effective diacritics line and original runway face.
In view of markings may be stained, single photoelectric sensor 9 may generate erroneous judgement, when multiple photoelectric sensors
When 9 row, it will be able to effectively reduce False Rate.
About piggyback pod 4, driving equipment is mainly installed, control equipment can also be installed, control equipment is based on automatically controlling
Intelligent device, such as controller should be protected, since the forms of motion on chassis is fairly simple, the algorithm being adapted to is also fairly simple,
For multiple photoelectric sensors 9, then mainly very with false judgement, institute's adaptation algorithm is also very simple, such as multiple for examining
Survey the photoelectric sensor 9 of blip line be it is true or most when being true, illustrate that chassis does not yaw.If the left side is so many,
The right is very few, then chassis can be determined further there may be yaw or carry out yaw steering based on probability, that is, drive
When moving such as deflecting roller 6 and do low-angle adjustment, such as being judged as yaw, 1 degree is adjusted, avoids adjustment excessive.
If photoelectric sensor 9 is completely used for the judgement of markings itself, the probability for generating erroneous judgement is bigger than normal, misses to reduce
Sentence probability, in a preferred embodiment, the row width of photoelectric sensor group is greater than the width of blip line, thus relative to
The part that mark line width goes out can carry out yaw judgement.
Specifically, photoelectric sensor group has photoelectric sensor 9 to be located at outside blip line at the both ends in row direction, and
It is denoted as border sensor, to drive chassis to deflect to corresponding side when border sensor samples blip line, such as positioned at
The border sensor in left side samples blip line, then it represents that chassis yaws to the right relative to blip line, in this situation
Under, controller control deflecting roller 6 is turned left, as previously mentioned, the angle changing rate for correcting yaw is small, is normally controlled in 1 ~ 5 degree, is avoided
Correction is excessive in short time.
Further, since there are the lateral marker lines on cross section, such as endless track for markings, if to ring marker
When line cleans, in markings infall, the border sensor positioned at both sides has maximum probability that may sample markings simultaneously,
Under this condition, it should be judged as that chassis does not yaw, i.e., when the border sensor on both sides all samples markings, should be judged as chassis
Do not yaw.
To avoid generation, there are interference when lateral marker line, can set a threshold value, i.e. side border sensor is adopted
It does not rectify a deviation at once after sample to markings, a time threshold is given, if other side border sensor in the time threshold
Detect markings, then it is assumed that chassis does not yaw, if other side border sensor does not detect in the time threshold
Markings, then it is assumed that yaw is produced, to carry out correction processing.
Preferably, the quantity of photoelectric sensor 9 is the odd number more than or equal to five in photoelectric sensor group, is located at row two
Each photoelectric sensor 9 at end is used as the border sensor, remaining photoelectric sensor 9 is used for the knowledge of markings itself
