Abstract

Abstract

Error detection is an important procedure during large quantity production of photoelectric encoder. At present, such error is mostly detected manually by judging sequences from binary LED arrays. This method is of low efficiency and extra error due to manual work, especially when large quantity is concerned. Given the defects of current methods, an auto-detection system for photoelectric encoder is designed in this paper. Firstly, the main reasons for the error are analyzed, and then an auto-detection method is proposed by adopting differential after referring to present works method. Lastly, an auto-detection system is established, utilizing a FPGA control chip. The system is capable of swift data acquisition and procession and its outcomes can be transported to a computer or displayed on a LCD. Experimental results show that the system is suitable for 15 bit series or parallel interface in different speeds. The system is intelligent, swift, portable and suitable for laboratory and other work situations, and the detection efficiency has been improved by 3-5 times.
