Development prospect of industrial communication technology and standards

[introduction: with the trend of industrial system towards distribution and networking, communication technology and networking technology have become one of the core contents of industrial automation technology. At present, there are many kinds of fieldbus, industrial Ethernet and industrial wireless communication standards in the world. How to choose the standards suitable for transformation?]

with the industrial system moving towards distribution and networking, communication technology and networking technology have become one of the core contents of industrial automation technology. The information transmission between factory production management system and production control unit, and between controller and various production equipment has become the lifeblood of industrial enterprises. Industrial communication technology has become an indispensable part of industrial automation technology. From fieldbus, industrial Ethernet to industrial wireless communication, the dispute over standards has become a strategic means of competition for major international enterprises. In the Chinese market with huge market space, major international industrial communication standards are coming one after another and rooted in China, and China's independent industrial communication standards are also developing in the bud

as the domestic counterpart of IEC/TC65, SAC/TC124 has actively participated in relevant national scientific research and international standardization activities for many years. On the one hand, a large number of international standards have been transformed. By the end of 2009, the standard acquisition rate of IEC/TC65 (industrial process measurement, control and Automation) international standards has reached 74%, and nearly ten industrial communication technologies such as PROFIBUS, MODBUS, CC-Link and Ethernet/IP have been transformed. A number of industrial communication standards are being formulated, which basically meet the needs of the development of industrial automation technology in China; On the other hand, China's independently formulated EPA and WIA-PA have been pushed to the international stage. These two standards have successively become IEC international standards, laying the foundation for China's independent technology to go international. According to statistics, as of May 2010, there were 1369 current standards in the instrumentation and automation industry, of which 934 were independently formulated standards, and the rest were international advanced standards

Transform international standards into national standards

at present, there are a variety of fieldbus, industrial Ethernet and industrial wireless communication standards in the world. How to choose the standards suitable for transformation? First of all, we should consider the needs of the Chinese market, that is, the application and popularization of this technology in the Chinese market; Secondly, the corresponding technology counterpart organizations are required to be truly open to the technology, support China's standardization work and create conditions for China's standardization work. They should also support domestic enterprises producing various devices to develop bus products. At the same time, the localization of communication technology consistency and interoperability testing is also an important factor. In this way, the adoption of international standards and China's independent national standards form an organic whole to form a predictable, open and dynamic industrial communication standard system, so that the effectiveness of the standard work can be shared by all parties in the society

the consequences will also be contrary

at present, a number of international communication standards such as PROFIBUS, MODBUS, CC-Link and Ethernet/IP have been incorporated into China's national standard system. On the one hand, it promotes the development of the application of industrial communication technology in China and cultivates a broad market space. At the same time, it also promotes the development of various automation products based on these standards in China; On the other hand, it has also played a good leading and exemplary role for domestic R & D and production application enterprises, promoted the research of China's independent technology and the development of related products, promoted the research and development of China's independent intellectual property technology, and shortened the technical level gap between China and developed countries in the research of industrial control network

how to develop China's independent standards

China's EPA and WIA-PA have successively become IEC international standards. Their driving force mainly comes from the desire of Chinese users and automation technology developers for independent technology and the policy guidance of the national government to actively promote independent technology research and development. However, after these standards become national and international standards, the market promotion is relatively slow. The main reason is that the product technical system is not perfect, and there are many obstacles in product selection when users design and apply, which limits the development of application

to solve this problem, we need to drive more enterprises to invest in the R & D of relevant products and form a more comprehensive and rich product chain. To drive more enterprises to invest, on the one hand, it requires the improvement of the technical system and standard system, including the development of software system, consistency and interoperability standards, evaluation standards, safety standards, installation requirements and the establishment of relevant test platforms. Only with perfect technology and standard system can enterprises standardize and promote the development of corresponding products, However, China's current independent technical standards have not been born for a long time, and some key technologies need to be continuously studied and improved; On the other hand, the promotion of industrialization requires greater policy encouragement and financial support from government departments. In the market economy, the behavior of enterprises is driven by interests. Only by allowing enterprises to see real benefits, can they give full play to their initiative and actively participate in the development of independent standard products. Therefore, the government should formulate more practical promotion policies for industrialization and effectively implement supervision. In addition, the maturity of any technology is inseparable from the application, so users' support for independent standard products is also indispensable

future development of industrial communication technology and standards

firstly, there is a trend of joint development and application of multiple companies or organizations in a field, such as Siemens, Emerson, abb and other large multinational companies jointly developing WirelessHART industrial wireless technology; Secondly, the system technology considered in the development of modern industrial communication technology is more comprehensive, such as improving its security, high availability, interoperability, integration and other indicators to better meet the needs of users; Thirdly, enterprises or technical institutions form close contact with user groups in the process of technology research and development, and carry out targeted research and development according to the needs of users. For example, when WirelessHART industrial wireless technology carries out technology development, it cooperates with Namur user organizations with great influence in Europe, and considers the needs of users in the process of development, so as to make the technology itself more targeted; Finally, due to the increasing scale of automatic control system, the compatibility of new and old systems, the coexistence, interoperability, communication security and vertical and horizontal integration of information between various control technologies and communication technologies and related products are also the development priorities in the field of industrial automation
