The Research Of System Of Subdivision Of Optical Encoder With MCS-51

In the course of industrial measurement and control,Often requires rotating spindle from the perspective of information,On the need to use as a rotary encoder sensors. Photoelectric encoder servo system is an important component of,Through its information collection point or displacement. According to the acquisition of different signals, servo system to adjust. The servo system is the core of the NC system. So its entire manufacturing sector is of great significance.Breakdown in industrial control in the important practical significance, based on the MCS-51 SCM photoelectric encoder breakdown of the circuit, is the view of the current sub-circuit the shortcomings of the sub-circuit system were studied. Circuit from light source, slit, receiving components, plastic surgery to enlarge, A / D converter, MCS-51 system, D / A converters, drives and other components of output. Receiver components of the change of perspective or displacement transmitted to the MCS-51 sub-output system. Sub-circuits can be called multiplier circuit. Mohr grating on the fringes of the signal frequency methods are widely the study of law, machinery, electronics, computer software and other law approach. The traditional frequency circuit in the actual application of the following limitations: 1. Multiplier number can not be too much2. Measurement complex structure, size, and some can not be measured for dynamic3. Modular production in poorSo the traditional encoder breakdown of the circuit design a new frequency circuit, much of it has overcome the limitations of traditional frequency circuit, is of important value. CPU module using low-power MCU AT89C52 as a master. Master to complete the acquisition signals a breakdown detection device output processing. In the SCM software design, modular software design, signals the completion of the collection, processing, and other parts of the preparation process, commissioning work.In logical, intelligent control, the MCU is irreplaceable advantages. At present, the SCM has been widely applied to the photoelectric rotary encoder data processing system design, through the flexible design of the SCM software can be achieved A variety of logic operation and control, use of top-down system design methods to shorten the development cycle, improve the efficiency of the design. 80 C196KC take full advantage of the high-speed mathematical treatment capacity so that it can better achieve the larger scene of the conditions for real-time digital processing and precise control. This structure has been successfully applied to photoelectric rotary encoders, made a good practical results.This shows that the design and practical application there is still a certain gap. In the future work and learning in a more in-depth study. Mainly in the PC integrated information processing module and the use of EDA approach to systems design, reduce the circuit design and circuit board design and the difficulty of the workload and improve the response rate Titong efforts.
