An angle displacement measurement system based on incremental photoelectric encoder is presented and the principle and hardware implementation are studied in this paper. The proposed system is composed of photoelectric encoder, specific decoder/counter module, microcontroller unit (MCU) and wireless communication modules.
A digital servo control system is constructed, which consists of single-chip microcomputer AT89S52, dedicated motion-control chip LM629, integrated and intelligent power output amplification circuit LMD18245 and Incremental Optical Encoder.
Testing device of press braking time with increment photoelectric coder has been introduced with both principle and method to test the time and angle and analysis of key circuit of the device which might become indispensable to forging equipment performance with high accuracy and easy use.
This paper introduces a method using 8096 procedure design for solving the position feedback sig- nal count mistake of optical chopper encoder at servo system oscillation and presents the foundation principle to realize digital filter replacing electric circuit by the software.
This paper introduces different methods of velocity detection using incremental encoder and the function of TMS320F2812 for velocity detection,and then analyses a method of M/T based on DSP,discusses the implementing path of the hardware and software.
