Chip for high-precision servo drive control system of optical fiber fusion splicer and its control method

Abstract

The invention discloses a chip used for an optical fiber fusion splicer high-precision servo drive control system and a control method thereof. A phase-locked loop module is connected with an image sensor clock generation module through a frequency divider. An electrically erasable programmable memory is connected with a serial communication interface. The serial communication interface is connected with a core control chip CPU. A serial communication bus module and a serial communication command processing module are connected with the core control chip CPU. The serial communication command processing module is connected with the serial communication bus module, a key scanning module and a limiting detection module. The serial communication command processing module is connected with a liquid crystal backlight control module through the liquid crystal backlight control module. The serial communication command processing module is connected with a servo motor through a stepping motor drive control module. The problems of low splicing quality and short service life of the optical fiber fusion splicer caused by the fact that the present optical fiber fusion splicer is high in power consumption, low in efficiency and poor in reliability and can only realize fuzzy control can be solved.

Description

technical field [0001] The invention belongs to the technical field of optical fiber communication connection and maintenance, and relates to a chip for a high-precision servo drive control system of an optical fiber fusion splicer and a control method thereof.
