Unified Textile Equipment Interface, Technology Is Not Difficult

Because different mobile phone chargers can not be used each other, it brings a lot of inconvenience to our daily life, and also creates a great waste: to eliminate a cell phone, we must throw away a charger.

The main reason why mobile phone charger can not be used is that the interface of charger is not uniform. As long as the interface is unified, all problems will be solved. The problem of non-uniform interface is also existing in the textile field. With the deepening of enterprise information management, the problem of unified communication interface of textile equipment network management is becoming more and more urgent.

Interface is not uniform and equipment is difficult to connect.

With automation technology from single machine control to union Machine (multi machine) control, factory automation development, textile production enterprises carry out on-line collection and processing of output and quality information in production process, and use computer network system to monitor production and equipment operation status in workshop or enterprise management level, and demand for production planning, quality, consumption and other management is increasing. However, due to the fact that the equipment developed by the textile machinery manufacturing enterprises is not standardized, the description of the same machine information format is not uniform, and the communication interface of the field equipment is not uniform, which brings difficulty to the information recognition and reading of the enterprises. Some equipment did not consider the communication interface with the workshop control layer, some of which had communication interfaces but varied, which affected the equipment interconnection of textile enterprises.

At present, most of the informatization work in textile enterprises has realized local applications such as purchase, sale, storage, office automation and cotton blending management, especially in the cotton textile enterprises, which has exceeded 60%. However, production monitoring and quality testing are one of the weak links of textile enterprises. Cotton textile enterprises participate in the two integration evaluation of the Ministry of industry and information, and realize online monitoring through the network. Testing The coverage rate of the machine is 21.9%, and the coverage rate of the on-line monitoring machine is only 18.7%. This fully shows that there is still much room for improving the online monitoring and testing informatization. It should be realized by improving the digitalization level of the equipment and promoting the use of online monitoring and testing system.

Interface standards promulgated, most enterprises wait and see

There are many kinds of equipment involved in cotton spinning enterprises, including blowing carding, drawing frame, comber, roving frame, spinning frame, self winding machine and so on. Due to the different types, different manufacturers, and different types of controllers in the equipment, the communication interfaces and supporting protocols of controllers are different.

In order to guide the development and production of textile equipment from different manufacturers to meet the requirements of the equipment interconnection, in 2007, the China Textile machinery and equipment industry association took the lead in formulating the FZ/T 90108-2010 "cotton textile equipment network management communication interface and specification" industry standard, and promulgated it in August 2010. This is also the first digital information technology standard in the textile machinery industry, which has made a good start for standardizing the interconnection of textile machinery equipment. Sun Liangyuan, professor and senior engineer of the China Textile machinery and equipment industry association, who has drawn up and participated in the "cotton textile equipment network management communication interface and specification" standard, said that the purpose of setting up the industry standard is to facilitate the production of cotton spinning equipment manufacturers to choose the appropriate industrial control network in the design of the new machine, reserve the standard communication interface, and provide reference for the cotton mill's centralized control system construction and equipment selection. communication interface standard It is a recommended standard. If cotton spinning equipment manufacturers can use this standard as reference, the communication interface of equipment should be unified as soon as possible. This will play a positive role in promoting the information management of cotton textile industry and promoting the two fusion of cotton textile enterprises.

"Cotton spinning equipment network management communication interface and specification" industry standard has been published for more than a year, but the promotion process is relatively slow. Most spinning machinery enterprises do not respond quickly, but are waiting for the attitude of the user enterprises. Although the textile enterprises have attached great importance to the information-based management of the enterprises, they still do not know enough about the efficient database management that may be brought to the enterprises after the equipment networking. Therefore, the demand is not strong. Only a small number of information-based enterprises are in the front of the textile enterprises, and they invite the textile machinery enterprises or electric control system enterprises to spanform the equipment interfaces in the workshop.

Implementing interface unification is not a difficult point.

Sun Liangyuan said that in the formulation of the industry standard for the communication interface and specification of cotton spinning equipment network management, the feasibility of standard implementation was not only considered in order to facilitate its popularization and application, but also considered the advanced nature of the technology and ensured the sustainable development of technology. At the same time, it also paid attention to the advanced technology and development trend of the famous cotton spinning equipment networking in the world, and approached the international level as far as possible. For this reason, the standard recommends several kinds of communication protocols and interface types that are mature, versatile and widely used, but strive to avoid restricting technological innovation.

"All enterprises need to make individual adjustments to the original system data so that they can be unified to the standard." Jin Guang Cheng, deputy general manager of Jingwei Textile Machinery New Technology Co., Ltd. implements the industry standard of "cotton spinning equipment network management communication interface and specification", which is technically difficult for spinning machinery enterprises. He said that when making equipment networking for the user enterprises, if the manufacturers of different equipment give active coordination and open communication protocol, then the interface unification can be easily achieved; if the host enterprise does not disclose the agreement, then the communication interface needs to be reformed. Generally, we should add communication modules, upgrade CPU types, or replace the controller products.

"All devices are networked to achieve centralized production and equipment. Monitor It is the specific requirement for the integration of cotton and textile two technologies, and also the management mode that cotton textile enterprises must change from extensive to intensive. "Ye Jianchun", Deputy Secretary General of the China Cotton Textile Industry Association, said that during the "12th Five-Year" period, the cotton textile industry should promote the industrial structure adjustment with the integration of two technologies, and infiltrate the information technology into the whole process of cotton textile production. Through the application of information technology, the enterprise's internal management, technological development, product design, online testing and marketing methods will be changed to achieve the upgrading of the textile industry. He urged cotton spinning enterprises to reconnect and work on equipment networking as soon as possible.

In order to let cotton textile equipment manufacturers and cotton textile manufacturers further understand the specific contents of the "cotton textile equipment network management communication interface and specification" industry standard, and promote the unification of the interface standard of cotton spinning equipment, in December of this year, the China Textile machinery and equipment industry association and the China Cotton Textile Industry Association jointly organized the propaganda standard of this industry standard. Jingwei Textile Machinery Co., Ltd., which has the capacity of producing cotton spinning sets, is very active in implementing the industry standard of "communication interface and specification for network management of cotton spinning equipment". After the meeting, the company immediately called the subordinate enterprises and deployed the unified network communication interface work. Jin Guangcheng said that the unified interface is more prominent for Jingwei AG, and it is easier for them to sell their equipment.
