First class enterprises set standards, second tier enterprises to do the brand, the three flow of enterprises to sell technology, the four flow of enterprises to do the product has become a universal recognition of the law of economic development, the standard is actually a dispute over the market. Who mastered the standard, it means that the first to get the market ticket, and even become the industry's definition. The fierce competition in the field of industrial communications is particularly evident. Because of the reason of technology, all kinds of industrial communication protocols are combined with the original low speed fieldbus application layer protocol. Inevitably, the contention of the fieldbus continues to the increasingly stringent Industrial Ethernet standards, and then continues to the current industrial wireless technology standards.
In western countries, many companies are actively involved in the formulation of national standards." Shi Baoquan, deputy director of the National Standardization Management Committee, said in an interview that the motivation of these companies is nothing more than a standard who have the world. "The technology industry standards can best embody an industry, and enterprises to participate in the development of industry standards will try to put the enterprise technology embodied in, once led the development of the enterprise technical standard by experts of the national organization, it is the state for the promotion of products of the enterprise benefit, it is self-evident."
Industrial wireless technology international standards competition fierce competition
The national standard of industrial wireless technology continues to dispute the fieldbus standards and the characteristics of the industrial Ethernet standards.
Internationally, the HART communication foundation and the United States instrumentation systems and Automation Association ISA, represented by hundreds of member units, with the support of many multinational companies, actively carry out the work of the relevant standards. IEC TC65 (industrial measurement and Control Technology Committee) in September 2006 also began to develop international standards. However, due to the limitations of the world and major companies for commercial interests and technical research and development bottlenecks, IEC standards for the development of a very intense debate. One interesting episode is, in HART 7 (wirelessHART) two days before the launch of the standard, Honeywell announced the company as a member of the board of the HART foundation, is opposed to the introduction of WirelessHART. In a statement, the president of Honeywell's process control department suggested that the HART foundation be able to adopt the ISA SP100 standard. Because, one of the most significant difference is: wirelessHART development is only to support the HART protocol, and the ISA SP100 standard can support HART, Profibus, CIP, FOUNDATION Fieldbus and other protocols." The importance and complexity of international standards for industrial wireless technology.
WIA-PA wireless network for industrial process automation in China (Wireless Networks for Industrial Automation-Process Automation) specification is led in the Chinese Academy of Sciences Shenyang Automation Research Institute deputy director Yu Haibin, Ceng Peng, Xu Aidong and fellow researcher, joint Zhejiang University, mechanical instrumentation technology and Economy Research Institute, Chongqing University of Posts and Telecommunications, Shanghai Industrial Automation Instrument Research Institute, University of Science and Technology Beijing Southwestern University, Shenyang microcyber Corporation, Zhejiang in the control group, Northeastern University, Dalian University of Technology and other companies by Chinese scientists developed successfully. WIA-PA specification in October 31, 2008 after the International Electrotechnical Commission (IEC) of all Member States to vote, with 96% of the vote to get through, as publicly available specification IEC/PAS 62601 standardized documents released. To make the industrial wireless technology international standard wirelessHART (HART Foundation), ISA 100.11a (ISA), WIA-PA (China) a situation of tripartite confrontation situation.
Industrial wireless technology has been listed as the key project of "the research and development of industrial wireless technology and networked measurement and control system" in China's "863" plan in 11th Five-Year. Has been a breakthrough based on the RF environment cognition and adaptive frequency hopping communication technology, high reliability and low energy consumption based on the technology of high precision synchronization and event driven and based on space, time and frequency of multidimensional scheduling real-time communication technology and other core technologies. To establish the technology system with independent intellectual property rights, including the development of the wireless adapter, routers, gateways, communicator, network support equipment, construction of the test environment, and application in metallurgy, petrochemical, electricity, sewage treatment and other industries have achieved good results.
WIA-PA technology to promote automation technology in China
Measurement and control Standardization Technical Committee of national industrial process (SAC/TC124) secretary general professor Ouyang Jinsong pointed out that WIA-PA autonomous wireless standards in China as an international standard has important significance for the development of industrial wireless technology in China and even the whole automation industry.
Industrial wireless technology as the forefront of the field of industrial automation technology, leading the future direction of industrial automation systems. Industrial wireless technology is a new wireless communication technology, which is oriented to the information exchange between devices. It is the extension and promotion of the existing industrial communication technology in the industrial application. It will lead to the change of traditional industrial measurement and control mode, and lead the development of industrial automation system in the direction of low cost, high reliability and high flexibility. Europe and the United States and other governments have repeatedly pointed out in the development plan, industrial wireless technology will play an important role in improving product quality, reduce production costs, improve energy efficiency and so on. The U.S. Department of energy also classified industrial wireless technology as one of the main technical means to achieve a 5% reduction in overall energy consumption by 2020.
