Intelligent control system of pattern sewing machine

Abstract

The invention discloses an intelligent control system of a pattern sewing machine. The intelligent control system comprises software, hardware and a structural system. The structural system comprises an electric cabinet, the hardware comprises a spindle control subsystem and a subsystem controlling a needle rod mechanism, a delineating mechanism, a thread picking-up mechanism, a feeding mechanism and a presser foot mechanism, the spindle control subsystem is provided with a position closed-loop control motion control module and a spindle system failure process and enabling control module, the needle rod mechanism, the delineating mechanism and the thread picking-up mechanism are controlled through an alternating current servo motor, the feeding mechanism is controlled through an XY motor, and the thread picking-up mechanism and the presser foot mechanism are controlled through a stepping motor; a hardware system core is composed of a DSP+ARM double-core system and comprises a bottom layer control platform and an upper layer human-computer interface, the bottom layer control platform is controlled through two main processing chips of a TMS320F2812 and an LC 5512 in real time, and the alternating current servo motor and the stepping motor achieve multi-axis linkage. The DSP+ARM double-core system is high in operating efficiency, displaying of a seven-inch touch screen is achieved through true color images, an operation panel is visual and concise, and a system hardware frame is high in universality.

Description

technical field [0001] The invention relates to a control system of sewing equipment, in particular to an intelligent electronic control system of a pattern sewing machine. Background technique [0002] Pattern sewing machine is the most common special sewing machine, which is widely used, such as handbags, shoes, bags, leather goods, especially in clothing enterprises, and even in home decoration industries such as curtains, wall coverings and furniture factories. , the electronic pattern sewing machine can reproduce it at high speed and efficiently after the operator or designer selects the corresponding pattern according to the pre-drawn pattern, which is unmatched by traditional manual sewing. In recent years, many kinds of electronic pattern sewing machine products have appeared at home and abroad, but the electronic control system of these existing electronic pattern sewing machines is basically composed of a single-chip microcomputer plus a motor-driven control board,...

AI Technical Summary

Problems solved by technology

This electronic pattern sewing machine control system overcomes the shortcomings of the previous pattern sewing machine control circuit composed of two single-chip integrated circuit boards, and instead uses two ARM chips as the master-slave control chip. Compared with the original technology, this The control system can be regarded as having improved processing power
