Description of drawings
Fig. 1 is the general frame synoptic diagram of the utility model two-dimension displacement proving installation;
Fig. 2 is the structural representation of the photoelectric sensor module of the utility model two-dimension displacement proving installation;
The schematic perspective view of the optical lens that Fig. 3 is adopted for the utility model two-dimension displacement proving installation.
Embodiment
As shown in Figure 1, be the one-piece construction synoptic diagram of the utility model two-dimension displacement proving installation, each module is electrically connected each other.The workflow of whole device roughly is a power-on-reset at first, each module enters duty, the change information of the displacement of the measurement two-dimension displacement proving installation that the photoelectric sensor module is continuous, this mainly is earlier by successively outside reference being carried out picture shooting, successively picture shot is carried out special analyzing and processing then, go out the change in displacement of two-dimension displacement proving installation according to the various computing of front and back pictures taken, and this change in displacement is converted to increment size (the Δ x of coordinate, Δ y), then with this displacement data, be that the increment of coordinate value sends to the optical fiber type control module, the optical fiber type control module is passed through the displacement data that receives the format conversion of data, make the data after format conversion can help the processing of single-chip microcomputer, sending the data to one-chip computer module then handles, one-chip computer module carries out certain analyzing and processing to these data after receiving the data that the optical fiber type control module sends, and the displacement data that receives carried out accumulation process, displacement data after this is added up is converted to two-dimensional coordinate data, then this two-dimensional coordinate data is sent to data disaply moudle.The data that show by display module promptly are the position coordinate datas of two-dimension displacement proving installation, can directly draw the change in displacement of two-dimension displacement proving installation according to the true origin of setting.If whole two-dimension displacement proving installation and a moving object are fixed together, the displacement information of the two-dimension displacement proving installation that then records promptly is the displacement information of this moving object, thereby has measured the displacement of moving object.
Because this two-dimension displacement proving installation is integrated by several modules, so whole apparatus structure compactness is installed also very convenient; Again because only need to set a true origin, thereby only need a reference point, the variation of the continuous perceptual object displacement of photoelectric sensor module, thus make the precision of test result and accuracy that good assurance all arranged.
As shown in Figure 2, structural representation for the photoelectric sensor module of the utility model two-dimension displacement proving installation, comprise a circuit board 4, this circuit board 4 is fixed in the shell 6 by screw 5, light emitting diode 3 is welded on the circuit board 4, and this light emitting diode 3 can send the light of certain intensity after the energized.On circuit board 4, also be welded with an optoelectronic induction chip 1, the utility model is this optoelectronic induction chip 1 ADSL-2051 optoelectronic induction chip that is Agilent preferably, see also the related description book of this chip for the detailed operation principle of this chip, the utility model is just used this chip, at this it is no longer described for the principle of work of known technology.
The major function of optical fiber type control module is that the data from photoelectric sensor are carried out format conversion, this module mainly comprises a light formula control chip, the utility model preferably model of this optical fiber type control chip is mdt80c06, this chip is converted to the data of PS/2 form with its data that receive, and the data of PS/2 form help the processing of one-chip computer module.
One-chip computer module mainly comprises a singlechip chip, and the utility model preferably uses 89S52 model single-chip microcomputer.This module functions is that the PS/2 formatted data from the optical fiber type control module is handled, and this data processing is converted to can show two-dimensional coordinate data, and this two-dimensional coordinate data is sent to data disaply moudle.Single-chip microcomputer is roughly the processing procedure of the data of PS/2 form, Single-chip Controlling display unit data presented was zero when at first start resetted, promptly Ci Shi coordinate is (0,0), when optical fiber type control module transmission data are come, just begin the data that receive are handled, judge the direction of these data earlier, be that each dimension coordinate increases progressively or successively decrease, the directional information of these data is included in the data that one-chip computer module receives, thereby single-chip microcomputer can directly be judged that data increase progressively or successively decreases, if increase progressively, then singlechip chip adds the value that receives on former coordinate basis, if the then single-chip microcomputer that successively decreases deducts the value that receives on original coordinate basis, and new coordinate figure of so final formation.One-chip computer module sends to display module so that in time show with new coordinate data after the data processing that receives is finished immediately.One-chip computer module all is that the data after handling immediately and will handling in time send to data disaply moudle after receiving new data, to reach the measured coordinate figure of real-time demonstration.
Data disaply moudle, mainly comprising of this module shows that charactron and corresponding driving circuit thereof, major function are exactly that the coordinate data that one-chip computer module sends is shown in real time.The groundwork process of this module is exactly that driving circuit is accepted the data by the one-chip computer module transmission, then the data that receive is shown by driving described charactron.
The foregoing description only is for the present invention will be described, rather than limitation of the present invention, those skilled in the art will appreciate that without departing from the inventive concept of the premise, and the utility model also has many modification.
