Abstract
The invention relates to an angle digital sensor. The optical disk comprises a coded disk 1 and a photoelectric sensor 4, wherein the coded disk 1 is a disk with teeth 2 on the outer circumference, and the center of the photoelectric sensor 4 is arranged corresponding to the teeth 2 of the coded disk 1. The invention solves the technical problems of high requirement on working conditions, complex manufacturing process and high cost of the angle digital sensor in the background technology.
Description
One, technical field
The present invention relates to a kind of digital sensor of angle.
Two, background technology
Often running into measurement of angle in the real work, generally is the digital sensor of angle that adopts the photoelectric code disk structure, directly exports digital quantity, and this is one of the most direct method of measurement of angle.Traditional digital sensor of angle has two classes: 1, increment code wheel, when code-disc rotates, provide a series of signal, and carry out plus-minus counting by follow-up circuit according to rotating.2, absolute value code-disc, it does not need computing, can both provide fixing and the corresponding digital quantity in measured axis position at an arbitrary position.These two kinds of code-discs are to the requirement of photoelectric detector all very high (as shape, structure, installation etc.), and the follow-up circuit complexity of increment code wheel, and the technology difficulty of absolute value code-disc is very high, be provided by professional manufacturer, and cost is very high.
Three, summary of the invention
The digital sensor of angle condition of work that the invention solves in the background technology requires height, complex manufacturing technology and the high technical matters of cost.
Technical solution of the present invention is: a kind of digital sensor of angle, its special character is: this digital sensor of angle comprises code-disc 1 and photoelectric sensor 4, code-disc 1 is the disk of an excircle band tooth 2, the tooth 2 corresponding settings of the central authorities of photoelectric sensor 4 and code-disc 1.
Above-mentioned code-disc 1 is one.
The number of teeth of above-mentioned code-disc 1 is two or more.
Above-mentioned photoelectric sensor 4 is two or more.
Above-mentioned photoelectric sensor 4 is GK320 type, GK225 type or GK285 type sensor.
The present invention adopts code-disc and photoelectric sensor isolating construction, and the condition of work of photoelectric detector is not required, and it is simple in structure, at the bottom of the cost and difficulty of processing low.
Four, description of drawings
Accompanying drawing is a structural representation of the present invention.
Five, embodiment
Referring to accompanying drawing, the simplest structure of the present invention is that a code-disc 1 and two photoelectric sensors 4 of adopting rotating shaft 3 to install are formed, and code-disc is the disk of a band tooth 2, when rotating shaft drives the code-disc uniform rotation, and the photoelectric sensor output waveform of two correspondences.All from a code-disc number of winning the confidence, their output note is made G1 and G2 with two photoelectric sensors, with the XOR signal (note is made G1 G2) of logical circuit generation G1 and G2, fixes a photoelectric sensor, regulates the position of another photoelectric sensor at circumferencial direction.When code-disc at the uniform velocity rotated, the waveform with oscillograph observation G1 G2 transferred to 50% with dutycycle.The state of G1 level when utilizing the G2 level translation, follow-up circuit can be judged the state of rotating shaft: be just to change or reverse, determine plus-minus counting thus, obtain corresponding angle value.High-low level to G1 G2 signal is all counted, and the angle explanation that then can monitor is 360 °/4n (n is the code-disc number of teeth).
When accuracy requirement is higher, can increases the number of teeth of code-disc or increase photoelectric sensor.As adopt three photoelectric sensor output waveforms, during signal Processing, earlier with G1, G2 XOR and then and G3 XOR.The dutycycle that will make final signal during installation is 50%.At this moment angle resolution can reach 360 °/6n.
