Description
Technical field
The present invention relates to a kind of position detecting system, be specifically related to a kind of for metrical error and vectoring error correct system and method.
Background technology
Existing position detecting system generally adopts optoelectronic switch reflactor type.It generally comprises Mechanical Moving platform, infrared light supply and reflector, and infrared light supply and reflector are located on Mechanical Moving platform, and described reflector adopts rough reflective surface.It utilizes diffuse reflectance to confirm, and whether front detection target exists error, is generally used for and whether detects target in front.But this position detecting system cannot detect the left and right upper-lower position deviation of target in front, in other words its cannot determine error be relative to center left, to the right, upwards, downward position deviation direction, also cannot carry out error transfer factor voluntarily by guiding device.Also have the locating device of error detecting single shaft in prior art, but all complex structure, installation accuracy require high, cost is high, and relevant with the relative position of two inter-agency firm bankings, cannot complete detection error.
Summary of the invention
A technical matters to be solved by this invention is, there is provided a kind of for metrical error and vectoring error correct system, this system can be used for detecting the error up and down relative to center and vectoring error correction, and structure is simple, installation accuracy requires and cost is lower.
Technical solution of the present invention is, provide a kind of have following structure for metrical error and vectoring error correct system, comprising: generating laser, for launching site laser; Reflector, carries out mirror-reflection for the laser gone out laser transmitter projects; Photographic plate, for detecting the laser signal of reflector reflection; Signal processor, is electrically connected with photographic plate, for the treatment of the signal that photographic plate transmits; Equipment control center, is electrically connected with signal processor, the result of display processor; Signal processor receives the reflects laser point position signalling that photographic plate sends, and calculates with the center position stored the direction whether target object location has deviation and deviation more afterwards, flows to equipment control center in real time to carry out offset correction.
Compared with prior art, of the present invention for metrical error and the system that vectoring error corrects have the following advantages: of the present invention for metrical error and the system that vectoring error corrects comprises reflector for carrying out mirror-reflection to a laser, what adopt is mirror-reflection instead of diffuse reflection, the deviation relative to 360 degree, center in plane can be detected, and this system architecture is simple, relatively low to the requirement of installation accuracy, easy for installation, cost is also relatively lower.And by detecting the direction that can obtain the deviation of relative centre point position, target location, thus by adjusting the bootable correction error in position of generating laser and/or reflector.
In one embodiment of the invention, described photographic plate adopts CCD photographic plate.More responsive to light.The laser signal of reflection can be received preferably, and convert the signal received to digital signal transfers to signal processor.And CCD photographic plate technology is relatively ripe, cost is lower.
In one embodiment of the invention, described reflector is flat taper shape, and the reflecting surface of described reflector is smooth plane.The flat conical structure correspondence of reflector forms limit range inner region and limit range outskirt.Limit range inner region determines the size of location permissible error, when the some laser of laser transmitter projects is radiated at the limit range inner region of the plane of reflector, laser vertical is reflected back initial point, photographic plate does not receive signal, illustrate that subject performance platform is in limit range, location is normal namely in the error range allowed.When the some laser of laser transmitter projects is radiated at limit range outskirt and the corresponding circle conical surface position of reflector, the angled opposite direction reflexing to photographic plate of laser.When namely incident ray exceeds the limes superiors of reflector, reflects laser point appears at the below of the central point of photographic plate; Otherwise, if penetrate light when exceeding the smallest limit of reflector, penetrate the top that luminous point appears at the central point of photographic plate.Around this principle, the bias direction of light 360 degree can be detected.Signal transmission can be calculated the direction of skew by photographic plate to signal processor, and guiding device carries out moving with correction error.
In one embodiment of the invention, the distance between described generating laser and reflector is 0 ~ 50m.Due to adopt is a laser and mirror-reflection, can detecting distance relatively long.
In a preferred embodiment of the invention, the distance between described generating laser and reflector is 0.3 ~ 5m.Error-detecting within the scope of this is more accurate, more convenient with correction.
In another preferred embodiment of the invention, described generating laser, photographic plate and signal processor are as a whole.Entirety moves, more convenient when correction error, more efficient.
Another technical matters to be solved by this invention is, provides a kind of metrical error and the method for vectoring error correction.
For this technical matters, the technical solution of employing is, adopts of the present invention for metrical error and the system that corrects of vectoring error, and to comprise the following steps:
1) generating laser is to reflector launching site laser, reflector will put laser reflection to photographic plate, by the laser spot position that photographic plate detection reflector reflects, and laser spot position is fed back to signal processor, signal processor is by comparing with the signal location stored, calculate the direction whether target object location has deviation and deviation, and flow to equipment control center during fructufy by signal transacting; 2) according to the result of equipment control center display, the position of adjustment generating laser and/or reflector, to eliminate deviation.
In step 2) in when there is ultralimit, the deviation that mobile generating laser and/or reflector provide according to signal processor makes reflected light move to central point in the other direction, when reflected light jumps to central point from the super point of accumulation CCD, mobile platform continues the radius distance of the limit range inner region to the mobile reflector of deviation opposite direction, reach the limit of district center and the centre of location in scope to complete error correction and guide, now the center of the light source center of generating laser and reflector on the same line.
Can also can more efficiently be corrected error by metrical error accurately, easily by above step.
