Description
Technical field
The utility model relates to a kind of individual pen absolute encoder
,relate in particular to a kind of individual pen absolute encoder for part-turn electric actuator.
Background technology
Conventional electric topworks realizes valve opening counting with pot, pot utilizes swept resistance principle, owing to being contact slip, long-time use easily causes the problems such as loose contact, output signal shakiness, and the easy temperature influence of pot, temperature is waftd greatly, counting precision is poor, be not suitable for frequent high precision regulates.Also have part electric operator to count with Hall element, it is less that this counter technology acuracy is high, nothing is worn and torn, temperature is waftd, but owing to utilizing relative know-why, after power down, can not count, and easily causes technology to lose, and this is unallowed in actual motion.
The recent development due to technology, originally the absolute encoder that was applied to military project, Aeronautics and Astronautics, high-end exact instrument starts to be applied in electric operator counting unit, absolute encoder claims again Photoelectric angular position transducer, it is a kind of light, mechanical, electrical digital angle measurement device that integrates, absolute encoder has that resolution is high, do not affect normal counting after power down, without wearing and tearing, not affected by environment, the advantage such as reliable and stable is the first-selection of electric operator counting unit.

Accompanying drawing explanation
Fig. 1 is that the utility model is for the structural representation of the individual pen absolute encoder of part-turn electric actuator;
Fig. 2 is the structural representation of code-disc.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
Refer to Fig. 1, Fig. 2, a kind of individual pen absolute encoder for part-turn electric actuator, the control box that is arranged on part-turn electric actuator is inner, comprise data collector and data processing equipment, described data collector comprises main shaft 1, code-disc 2, slit plate, light-emitting component 3 and photelectric receiver 4, described code-disc 2 is fixed on main shaft 1, and described light-emitting component 3 and photelectric receiver 4 are arranged on respectively the both sides of code-disc 2.
Described code-disc 2 is circular, and code-disc 2 is along the circumferential direction divided into 256 sector regions, is transmission region and coding region alternately, the white hash mark of transmission region.In each coding region, be divided into again the fan-shaped window of 7, each fan-shaped window printing opacity or light tight, the logical value of the fan-shaped window of printing opacity is " 1 ", the logical value of light tight fan-shaped window is " 0 ", the fan-shaped window of 7 represents the area code code of this coding region, and area code code from 0000000 to 1111111 is arranged in order.
The light that light-emitting component 3 sends is irradiated on photelectric receiver 4 through code-disc 2, slit plate, wherein slit plate maintains static, code-disc 2 rotates with main shaft, form Moire fringe with the slit overlaid on slit plate, by photelectric receiver 4, received, main shaft 1 often turns over an angle pitch, and Moire fringe moves past a spacing, photelectric receiver 4 sends an electric signal, has just realized the conversion to input displacement.Photelectric receiver 4 is that one group of electric signal is delivered to data processing equipment by the code-disc pattern change of slit correspondence position, compare and enlarge, after integer, decoding, segmentation integer, demarcation, integer etc. process, calculate the relative shift of code-disc 2, the digital code output of last angulation, realized the measurement to angle, can realize detection of dynamic and control in real time.
In sum, owing to having adopted technique scheme, the utility model adopts absolute value code-disc, has realized high precision, high-speed digital communication output, without battery, no signal, disturbs, safer sooner, can realize detection of dynamic and controls in real time.
