Specific implementation mode
As shown in Figure 1, a kind of stone plate surface detection device of the present invention, including：For carrying slabstone 400 and can band
The horizontal rail 120 of separate/close 100 horizontal movement of scanning laser light source of dynamic slabstone 400；It is arranged in 120 one end of horizontal rail
For to 400 surface emitting scanning light beam of slabstone scanning laser light source 100 and about 100 assist in scanning laser light source vertically move
The wavelength of dynamic vertical track 110, scanning laser light source 100 is adjustable, and range is 380 nanometers~880 nanometers, vertical rails
The setting in road 110 can make the slabstone 400 of the adaptation different spans of scanning laser light source 100；In horizontal rail 120 far from vertical track
110 one end is vertically arranged the light-intensity test screen 200 for being useful for receiving the scanning light beam intensity signal after the reflection of slabstone 400, receives
The intensity signal of collection includes light intensity change direction and coordinate information；It is additionally provided with and detects model for light-intensity test screen 200 will to be exceeded
The light beam enclosed reflexes to the speculum 300 on light-intensity test screen 200, which is arranged perpendicular to light-intensity test screen 200,
300 one end of speculum is connect with 200 upper end of light-intensity test screen, and other end freely extends to scanning laser light source 100.
A kind of operation principle of stone plate surface detection device of the present invention is as follows：Slabstone 400 lies in a horizontal plane in level
On track 120, opens scanning laser light source 100 and adjustment scanning is moved up and down in vertical track 110 according to the span of slabstone 400
The height of laser light source 100 makes scanning light beam all arrive at light-intensity test screen after 400 surface of slabstone or speculum 300 are reflected
200；The scanning incident beam path domain that scanning laser light source 100 is sent out is from first edge light beam 101 to second edge light
Beam 102.
The operation principle of intensity signal：Scanning light beam is swept from first edge light beam 101 to the position of second edge light beam 102
When retouching, light-intensity test screen 200 collect intensity signal path be since B points upwards to A points, then from A points downwards pass through B points most
C points are reached afterwards.Wherein, when scanning light beam just arrives to 400 left side edge of slabstone, the projection on light-intensity test screen 200 is located at
The B points of light-intensity test screen 200；When scanning light beam reaches the position of turning point light beam 103, the projection on light-intensity test screen 200
It is located just at the junction A points of light-intensity test screen 200 and speculum 300；When scanning light beam just arrives to 400 right side edge of slabstone
When, the projection on light-intensity test screen 200 is located at the C points of light-intensity test screen 200.Since light-intensity test screen 200 is in B points and A points
Between section be projected twice, it is therefore desirable to record light intensity change direction as identification parameter.When light intensity change direction is by B points
A points are directed toward, indicate that scanning light beam is moved from the position of first edge light beam 101 to the position of turning point light beam 103；When light intensity becomes
Change direction and B points are directed toward by A points, indicates scanning light beam from the position up to turning point light beam 103 to the position of second edge light beam 102
It is mobile.When slabstone 400 be free from flaw and it is smooth when, scanning light beam is from first edge light beam 101 to the position of second edge light beam 102
When setting scanning, the intensity signal that light-intensity test screen 200 is collected is continuous；When there is crack in 400 a certain position of slabstone, scanning
The position intensity signal that light beam should be reflected at this on light-intensity test screen 200 will appear mutation, to know that slabstone 400 goes out
The specific location in existing crack.And manage that tested 400 coplanar flat of slabstone is flawless, the light intensity of light-intensity test screen 200A points position
Mutation must be will appear, reason has two：One, A points are located at the junction of light-intensity test screen 200 and speculum 300, scanning light beam
Projection is converted between two physical bodies, necessarily light intensity is caused to be mutated.Two, scanning light beam from the position of first edge light beam 101 to turn
Pass through two secondary reflections in the position moving process of break light beam 103, energy loss is that slabstone reflects energy consumption β 1 plus speculum reflection
Energy consumption β 2；And scanning light beam is only passed through from the position up to turning point light beam 103 into the position moving process of first edge light beam 101
Primary event is crossed, energy loss is that slabstone reflects energy consumption β 1；Therefore necessarily there is light intensity mutation at A.In order to solve necessarily to go out at A
The problem of existing light intensity mutation, horizontal rail 120 is set, translates slabstone 400 after completing first time Scanning Detction, make originally with
Pip on the corresponding slabstone of A points leaves original position and rescans detection again once.If there is light intensity at A points originally
The point of mutation be not mutated in being detected at second, then can exclude the point has crack, otherwise the corresponding original position of A points confirms
There is crack.
Collection and processing method of a kind of light-intensity test screen 200 presented below to intensity signal：If ambient enviroment light source pair
The background light intensity of light-intensity test screen 200 is A0；The scanning light intensity that scanning light beam is obtained in light-intensity test screen 200 is A1；Work as detection
When having crack to slabstone, scanning light beam is A2 in the crack light intensity of light-intensity test screen 200.Light intensity is used by sequence of coordinate information
Array is recorded：Such as set and be divided into 100 coordinate points between A points and C points, A point coordinates is 0, B point coordinates is 80, C point coordinates
It is 100.Light intensity record first array since B points is denoted as [79 A0, A1,20 A0], second array of subsequent time
It is denoted as [78 A0, A1,21 A0], then the third array that subsequent time obtains is denoted as [77 A0, A1,22 A0] ... it
The array of middle characteristic point A is recorded as [A2,99 A0] and the array of characteristic point C is recorded as [99 A0, A1].Utilize two
Adjacent array can judge that light intensity change direction, such as a certain array are designated as [60 A0, A1,39 A0], next
A array is designated as [61 A0, A1,38 A0], then this by light intensity change direction by A points be directed toward B points.When slabstone 400 certain
There is crack in any, then puts corresponding intensity signal and be recorded as [n A0, A2, (99-n) a A0] with array.
The scanning light beam that scanning laser light source 100 is sent out is incident to 400 surface of slabstone along 101 path of first edge light beam,
The reflected beams finally penetrate the B points in light-intensity test screen 200 after the reflection of speculum 300；If the light intensity of certain point is by script
A1 sports A2, then proves that there are cracks for the corresponding incidence point of the scanning light beam, and testing staff can be according to the number of intensity signal
