Rapier loom control system based on embedded flexible PLC

Abstract

The invention discloses a rapier loom control system based on an embedded flexible PLC. The system adopts a modularized design and comprises a flexible PLC development module, a multi-power-supply conversion module, a common input module, a common output module, a high-speed signal transmitting module, a high-speed signal collecting module, an analog input module, an analog output module, a Flashstorage expansion module, a communication interface module, an SWD debugging module, an Ethernet module and a wireless module; the system mainly takes an embedded control system platform as the support, the flexible PLC is solidified to the embedded control system platform, so that the embedded control system platform has the effects that the integrity is high, the manufacturing cost is low, the expansibility is high, and real-time industrial interconnection can be achieved, by adopting a flexible PLC system, the rapier loom control system has the function of achieving PLC programming, the simple programmability is achieved, the development cost is reduced, and the input of later maintenance can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of rapier loom control systems, in particular to a rapier loom control system based on embedded soft PLC. Background technique [0002] Since shuttleless looms replaced shuttle looms, my country has always been a major producer and exporter of textile products, which is also constantly promoting the development of my country's rapier loom industry. At present, foreign rapier looms have always been ahead of our country in terms of mechatronics, control effects, stability, and selection. Therefore, it is of great significance to develop independent core technology and improve the performance of rapier looms. [0003] From the perspective of the control system of rapier looms, the core of the current rapier loom control system is mainly based on PLC or single-chip microcomputer. The application number is 201721758416.5, which is a patent proposal for a rapier towel loom control system based on single-chip micr...

Problems solved by technology

[0003] From the perspective of the control system of rapier looms, the core of the current rapier loom control system is mainly based on PLC or single-chip microcomputer. The application number is 201721758416.5, which is a patent proposal for a rapier towel loom control system based on single-chip microcomputer. The single-chip microcomputer to build the rapier loom control system has the advantages of low production cost, easy production and strong integration, so it is favored by manufacturers. However, the technical requirements of the single-chip control system are relatively high. Once a system failure occurs, non-professional It is difficult for personnel to deal with the fault easily, which greatly increases the maintenance cost in the later period; the Chinese patent No. ZL201710185288.8 discloses a PLC-based rapier loom control system, using PLC to build a rapier loom control system, The advantage of the PLC system is that the PLC programming language is easy to learn, and its principle imitates the hardware wiring principle. Therefore, when the PLC control system fails, it is easy to know the cause of the failure and deal with it. However, the price of the PLC system is expensive. From the manufacturer's point of view, PLC is rarely used as the core to build the rapier loom control system
