Description
Technical field
The utility model is related to electronic device field, more particularly to the image measurer that a kind of integrated optical source is controlled.
Background technology
Radiographic measurement technology is an emerging measuring technology using computer vision as Research foundation.What it was represented is digital shadow
As science and technology dissolves in metering field, the advanced e measurement technology of space geometry computing is carried out.Image measurer is set up accurate in micron order
The hardware of numerical control with the basis of hommization operation software, various functions perfection is integrated, finally realize it is high-precision, multi-functional,
It is intelligent.The measurement of modernization.Image measurer has grown up the contemporary optics noncontact measurement of artificial intelligent type, passes
The excellent kinematic accuracy of digitized instrument and motion handling have been held, flexibility, the intellectuality of machine vision software has been merged
With the feature of automation, belong to the optical dimensions detection device of current forefront.
Kinetic control system is the important component in image measuring system.In the practical application of image measurer,
The positioning precision of motion control directly affects the quality of picture splicing.Therefore, invent a kind of for the efficient of image measurer
Kinetic control system is most important.
In existing radiographic measurement equipment, because optical ruler data acquisition, motor control, light source control use different drives
Dynamic control program, these programs are run on non real-time Windows operating system platform, can cause each control device can not
At least there is following defect or deficiency in efficient co-ordination, prior art：
1st, X/Y/Z motion controls are due to using open-loop control technology, it is impossible to eliminate transmission mechanism error, back clearance, Yi Jigong
Make the motor angle of operation deviation that the reasons such as platform Abbe error, and electrical system interference are caused, to realize positioning accuracy request
Survey Software need to read optical ruler coordinate position repeatedly, and send 2-3 motion positions according to deviation after once motion terminates
Operation could be completed to be accurately positioned, but the requirement of high efficiency measurement is wasted and be unable to reach which results in the time.
2nd, motion mode is measured：Board moves and stops at CCD alignment detected parts first, and board stops and waits for board
Stopping obtains image after rocking from CCD, and then board moves to next detected part, and so circulation completes all detected parts
Measurement, due to there is repeatedly starting and stopping, waiting the totally stationary grabgraf of board, has to be hoisted to the measurement efficiency of complex part.
3rd, man-machine interaction is generally using USB game control handles or USB industry control stick collection measuring instrument operator behaviour
Control is intended to, and data are sent to computer by USB, and the Windows Survey Softwares analysis identification for running on non real-time characteristic is manipulated
Bar sends back the data come and is converted into movement instruction, motion control card is issued to by PCI slot, due to HID class USB devices
Data communication relatively slow and Windows non real-time characteristic, causes operator's manipulation instruction to exist between being issued to board motion
Compared with large time delay, made troubles to operation.
4th, Survey Software is operated on Window operating systems, is non-real time operating system by Window, in 3D measurements
During, because process is blocked or responds sluggishness, and now probe collides with workpiece, because brake instruction can not be sent out in time
Go out board persistent movement, probe offset angle, which exceedes safe range, can cause hard ruby ball to occur strongly to touch with workpiece
Hit, cause equipment or workpiece damage, prior art carries out there is greater risk during 3D measurements.
5th, using analog quantity form, when board is static due to drift problem device be not present absolute inactive state but
Dynamic balance state, when optical ruler because installing space limitation can not be installed against transmission device.
6th, controller and compunlcation use usb communication, need independently installed driving, and communication distance is too short.And usb protocol is
Asymmetrical agreement, it is necessary to have main frame support, it is impossible to build star structure or bus-organization, whole equipment tree must have individual root
Node, between equipment and equipment can not direct communication, comparatively, Ethernet and serial ports are all the communication systems of equity.
