Paper Abstract

In order to improve the reliability of photoelectric switch type sensor and its anti-jamming ability to the outside natural rays and industrial highlight, this paper presents a photoelectric sensor based on the light digital link cyclic code type. In the light link of this sensor, a set of digital information is used to substitute the DC light information or the DC modulated light information of conventional sensor. And the sensing device implements strict digital sequential detection of the digital information. As this digital information hardly exists in the nature and industrial field, it is impossible to make interference to the light link. Therefore, the digital link cyclic code type photoelectric sensor is of high reliability and especially is not susceptible to the interferences in signal capture mode.
