Abstract

The invention discloses a control system of a circular knitting machine. The control system comprises an embedded system control panel, a parallel bus driving board and an electromagnetic needle selector unit. The embedded system control panel comprises an ARM [advanced RISC (reduced instruction set computer) machine] processor and a field-programmable gate array which are connected with each other by a parallel bus; the parallel bus driving board comprises a field-programmable gate array, and the field-programmable gate array of the embedded system control panel is connected with the field-programmable gate array of the parallel bus driving board by a parallel bus; the field-programmable gate array of the parallel bus driving board is connected with the electromagnetic needle selector unit by a parallel bus. The control system has the advantages that an ARM and FPGA (field-programmable gate array) dual-core processing effect can be realized, the control system can be operated via a touch screen, an eight-bit address and data time-sharing multiplex bus driving mode is adopted for controlling an actuating mechanism, accordingly, the real-time processing and control abilities of the system can be improved, and time-sequence requirements of high-speed control for different grades of circular knitting machines can be met.

Description

technical field

[0001] The invention relates to a control system of a circular knitting machine, which belongs to the technical field of textile machinery control devices. Background technique

[0002] Knitting circular knitting machine involves many fields such as electronics, machinery, computer, control, etc., and is a relatively complex typical mechatronics product.

[0003] At present, the circular weft knitting machine is developing in the direction of high machine number, multiple channels, high speed and strong auxiliary functions, and these technologies are mainly guided by Germany, Italy, Japan and other countries; limited by production, processing, assembly, control and other technologies However, there is still a gap between the stability and technological advancement of the domestic circular knitting machine system and foreign countries. Therefore, developing an advanced circular knitting machine control system has very important practical significance for enha...

Examples

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the examples, but not as a limitation of the present invention.

[0016] See Figure 1 to Figure 4 , The circular knitting machine control system includes an embedded system control panel, a parallel bus driver board, an electromagnetic needle selector unit, and the like. The embedded system control panel can realize the functions of pattern file reading and writing, control data analysis and organization, parameter setting, interface operation, etc.; the parallel bus driver board completes the signal preprocessing of the current running position of the circular knitting machine, control data forwarding, fault detection, emergency Stop control, etc.; the synchronization device is composed of a coupling, an encoder, and a zero position sensor. The coupling realizes the synchronization between the circular knitting machine gear and the encoder, and the needle positioning is realized through the A, B...
