Problems solved by technology

However, there are very few domestic manufacturers of CNC computerized six-color automatic thread-adjusting circular knitting machines that can be independently developed. The machines they have launched also have problems such as slow speed and low control accuracy, which are difficult to meet the needs of the development of my country's knitting industry.

Abstract

The invention discloses a real-time control system and a real-time control method of an automatic computer line adjusting machine. The real-time control system comprises a human-computer interaction unit, a real-time control unit and a mechanism executing unit, wherein the human-computer interaction unit is connected with the real-time control unit through an FPGA (Field Programmable Gate Array)-based dual-port RAM (Random Access Memory); the real-time control unit is connected with the mechanism executing unit. According to the real-time control system and the real-time control method of the automatic computer line adjusting machine, disclosed by the invention, the transmission of pattern data is quick, the control accuracy is high, the development period of products can be reduced, the production quality of colorful cloth is increased, and the production reliability of the system is ensured.

Description

technical field [0001] The invention relates to a real-time control system and a control method of a computer automatic thread adjustment machine, belonging to the technical field of numerical control of knitting machinery. Background technique [0002] Computer automatic thread adjustment machines are widely used in the knitting needle industry. At present, the computer automatic thread adjustment machines on the market are divided into 3 colors, 4 colors, 5 colors and 6 colors. However, there are very few domestic manufacturers of CNC computerized six-color automatic thread-adjusting circular knitting machines that can be independently developed. The machines they have launched also have problems such as slow speed and low control accuracy, which are difficult to meet the needs of the development of my country's knitting industry. Contents of the invention [0003] In order to overcome the slow knitting speed of the existing computer automatic line adjustment control sys...
