Problems solved by technology

However, it is an integrated control method, which does not separate the operation processing and control, so that the control system cannot realize the parallel operation of operation and control, thus slowing down the speed of the system and reducing the performance of the machine
At the same time, the sewing speed of 800 needles per minute cannot well meet the needs of high-speed electronic pattern machine movement.

Embodiment

[0027] With reference to the accompanying drawings, we will describe the high-speed motion control method of the electronic pattern machine involved in the present invention in detail.

[0028] D It can be seen that the motion control method involved in the present invention is designed and implemented on the basis of developing the embedded control platform of the electronic pattern machine. The control system consists of two parts: ARM9 pattern processor with S3C2410 as the core and mechanical control processor with ARM7TDMI as the core, which are connected by serial port RS485. ARM9 has a very high degree of integration, is the core of the present invention, and is also the support for the implementation of the method provided by the present invention, including a human-machine interface unit, a pattern editing and modifying unit, etc.; ARM7 is mainly used to control the mechanical part of the pattern machine, including Embr...

Abstract

The invention discloses a method for controlling high-speed motion of an electronic pattern sewing machine, which includes: when a spindle servo motor part moves at constant speed, a control system detects motional angle and position of a spindle motor so as to control X-axial and Y-axial motor motion; a scheme of double processing units, namely ARM9 (advanced RISC machine 9) and ARM7, is adopted to separate operation and control of pattern information, and accordingly different controllers can be used for implementing respective specific functions; and the ARM9 operates the pattern data based on a powerful data processing function of the ARM9, the data are transmitted to the ARM7 through a serial line, and the ARM7 can control sewing according to pattern processing results. By means of the double-processing-unit control scheme, control time is well saved, the performances of the control system are improved, sewing speed is increased, the ARM9 processing unit is freed while patter sewing is unaffected, and accordingly other operations are available.

Description

technical field [0001] The invention belongs to the technical field of numerical control, and in particular relates to a control method for high-speed motion of an electronic pattern machine. Background technique [0002] The electronic pattern machine is an indispensable and important sewing equipment in the production process of bags, shoes and hats. In view of the high-speed motion, the three-axis coordinated motion control method it adopts directly affects the performance indicators of this type of electronic pattern machine. [0003] The patent publication number CN 1794561 A discloses a motor motion control method for an electronic pattern machine. Although it realizes the continuous operation of the spindle motor, because the spindle speed of the pattern changes with the different stitches, it is difficult to realize the high-speed and smooth operation of the electronic pattern machine. jitter and other undesirable phenomena. In addition, the technical index that th...
