Description
Technical field
The invention belongs to and utilize the field of measuring technique of transmitting the output of sensing member, relate to a kind of senser element of measuring the physical quantitys such as the anglec of rotation, rotational speed, straight-line displacement for automatic field, specifically a kind of absolute matrix scrambler.
Technical background
Optical electric axial angle encoder is the sensor of the physical quantitys such as a kind of conventional measurement length, angle, speed, by the difference of coded system, substantially can be divided into increment type, absolute type and accurate absolute optical encoder three major types, wherein absolute photoelectric shaft encoder has absolute position counting, precision is high, reliable and stable, be subject to the advantages such as external interference is little.Machine tool, the digital value that brake system of car needs sensor to produce is sometimes indicated mechanical location.If Fig. 1 is the concept map of code-wheel and some contacts, according to Pan Zhuan position, contact produces 3 binary codings, has 8 such codings.Pan Zhongan region is connected with the signal source of corresponding logical one; Liang region does not connect, and contact is interpreted as logical zero.Use Gray code to the bright dark areas coding on code-wheel, make to only have a numerical digit to change between its continuous code word.The degree of accuracy that so can not manufacture because of device is unlimited, and makes contact forward boundary position to and occur error coded.
The core parts of optical electric axial angle encoder are code-wheels, comprise Fig. 2 code-disc and the slit plate shown in the Fig. 3 matching, and wherein code-disc is connected with scrambler main shaft, when main shaft rotates, drive code-disc synchronously to rotate.A side at code-disc is equipped with light source (infraluminescence pipe), at opposite side, photoelectric receiving tube is housed, and between code-disc and photoelectric receiving tube, slit plate is housed.The light that light source sends is through code-disc, and slit, is accepted by photoelectric receiving tube.When code-disc and slit generation relative angular displacement, photosignal is modulated into the strong and weak electric signal changing, through amplifying, and shaping, the sport technique segments such as decoding, output binary-level code.
Along with the needs in the fields such as industrialization and high-tech development and military project, scientific research, more and more urgent to the requirement of optical electric axial angle encoder miniaturization.The requirement of optical electric axial angle encoder miniaturization, must make the radial dimension of code-disc and slit plate dwindle or to adopting special method for designing on the code channel design of code-disc, but, after the size of code-disc and slit is dwindled, affect the effective width in code channel region, that is to say, if guarantee same resolution, code channel quantity is constant, can only reduce the width of code channel, like this to size reduce contribution very little; If guarantee that code channel width is constant, can only be to reduce code channel quantity, can cause like this encoder resolution to reduce.
The matrix coder dish that slit plate shown in code-disc shown in Fig. 2 and Fig. 3 matches and forms, can only export 8 bit codes, and the angle resolution of scrambler can only reach 1.40625 °.Therefore, require the radial dimension of code-disc to dwindle and don't reduce the output figure place of scrambler, will in the code channel layout of code-disc, take new method for designing.
Summary of the invention
The present invention has overcome the defect that disclosed technology exists so far, improve the angle measurement accuracy of scrambler, the physical dimension of dwindling scrambler, solves the needs of absolute type encoder miniaturization, the application and the usable range that expand scrambler, proposed a kind of novel absolute matrix scrambler.
