Wei Zhenggang: China's instrumentation industry is developing well

Introduction: In the past year of 2011, the first year of the Twelfth Five-Year Plan, we put forward the direction of the transformation of the economic development mode, put the good ahead of the speed, and proposed the cultivation and development of strategic new industries and specific seven industries. The development of high-end smart manufacturing equipment and so on, in addition to the importance of GDP and other indicators, but also pay attention to the concept of products and services. Wu Zhengzheng, a fieldbus professional committee of the China Instrument Industry Association, used this year-end and new-year opportunity to talk about energy efficiency, remote measurement and control systems, industrial automation instrumentation systems, and sensors.

Energy Efficiency Within the scope of energy conservation, the term energy efficiency has grown hotter. It stems from the white paper on energy challenges from 2010 to 2030 published by the Strategy Group of the IEC Standards Administration in March 2010. It is about energy efficiency and renewable energy. The future work in different fields put forward 34 constructions, including 3 proposals in the automation field:

It is suggested that IEC/TC2, SC22G, TC65 and ISO/TC184 should formulate guidance documents for the design and operation of energy efficiency systems in the fields of industrial automation and industrial process control from the perspective of the system.

In the production system design stage, in order to optimize the automation and production process, it is recommended that component or equipment standards include simulation data, such as simulation data optimized from the perspective of energy efficiency;

In the production system design stage, in order to optimize automation and production processes, it is recommended that the TC65 and its subcommittees develop simulation tools from the system's point of view, so that factory automation and production processes are optimized in terms of energy efficiency.

Under this circumstance, the joint working group JWG14 under IEC/TC65 is mainly responsible for formulating relevant standards for energy efficiency. In 2011, five meetings were held.

In addition to actively participating in standard setting, China has also implemented a lot of energy management practices. Energy measurement, control, monitoring, and regulation, from sensor to system, integration with production systems and separate forms, all exist. Now it is time to summarize Experience decides what to do next. The author does not comment on controversial issues for the time being. It is only for some basic measurement issues. He suggested that first trials should be conducted first, that the flow should be handed over and the trade should be handed over. It should be selected from standards, calibrations, design selection, installation, commissioning, acceptance, and operation and maintenance. In terms of accomplishments, this is the top priority for our professional instrumentation and automation professionals.

At present, domestic measurement technologies for natural gas, petroleum products, and water have made rapid progress. Ultrasonic flow meters, electromagnetic flow meters, Coriolis force mass flow meters, and multivariable transmitters have gradually become popular. In addition to wet calibration technology, dry calibration Technology has also been taken seriously. Some professional flow meters, such as heat meters for residents' heating charges and their meter reading systems, have gradually become popular products. This is the fourth form after the three tables. It is a people's livelihood project, and it is an energy conservation project. Energy conservation is a long-term issue. Doing a good job in basic inspection is the first level of automation technology.

In the 72nd issue of the CEC Magazine, a long-distance measurement and control system, an article was published on the wireless local area network WRAN by Mr. ApurvaMody, chairman of the IEEE 802.22 Working Group. This was a major event in 2011. It pointed out the direction for the Internet of Things and smart grid. The long-range and far-reaching remote measurement and control system in the automation profession points the way. The original remote measurement and control system was only a branch of the control system that was dominated by relative control, but it started from an industry with scattered detection elements and only needs supervision. The three remote or motion systems, data acquisition systems, and remote terminal units gradually emerged. Remote I/O, but due to the development of data communication technology, it gradually formed a modern remote measurement and control system. Its field layer covers RTV, fieldbus, wireless field instrumentation and other related technical products, and is also compatible with Internet of things RFID technology; The monitoring layer covers IEEE803.3, IEEE803.4 and other wired LANs and Internet TCP/IP and OPCUA technologies. It is the core of SCADA software and systems referred to today; its management layer is controlled by the central control room of the monitoring layer. Expanded to the metropolitan area network and multimedia technology, wireless communication wireless personal area network, broadband wireless metropolitan area network up to the beginning of this section of the wireless LAN.

At present, domestic automation professionals have made breakthroughs in the application of wireless personal area networks, especially ZigBee, and Shenyang Institute of Automation of the Chinese Academy of Sciences has pulled out WIA series products and loaded them into international standards.

As part of information technology IT, the automation industry should make use of the harmonious situation in the 3G era to make the remote measurement and control system a new growth point. It is said that the International Fieldbus Foundation has proposed the work process of ROM. In the near future, related DEMO demonstrations will also convey a message: The market reports of Frost & Sullivan forecast the global SCADA market to be US$4.5 billion.

Instrumentation and Sensors 2011 China's economy can be regarded as good on the landscape here. In the case of last year, the annual output value of Hollysys was RMB 3 billion; the annual output value of Zhejiang Zhongrong Company was RMB 200 million; the Yokogawa Instrument Company's annual sales of EJA pressure and differential pressure transmitters in 2010 alone. There are more than 200,000 units, and the total sales in the 10 years before 2009 were 1 million units. This fully proves that China's manufacturing capability is strong and the market is large. This shows that our automation industry should make greater achievements.

1. In the field of various field bus technologies that have been developed for more than ten years, China has been able to produce a variety of on-site meters. More than 10 FF field meters have passed the international registration certification, and other HART, Profibus, etc. In terms of systems, DCS manufacturers have been able to integrate HART, FF, and Profibus-PA into one DCS system at the same time. For example, DCS of Zhejiang Zhonghua produces FFH1 interface card AM712 modules, and each network segment can access 16 FF field instruments. FFBuilder hardware configuration software, FBD control strategy configuration software, alarm and event browsing software, diagnostic software, real-time monitoring software, SAMS equipment management software, and CIF on-site control function in FF technology are also provided.

2. In terms of functional safety, the integration of SIS and DCS has been accepted by people in addition to the use of specialized SIS systems. Domestic DCS manufacturers are also working hard on this. The application technology of functional safety has been popularized. There are technical teams in engineering applications such as standards, certification, training, design, installation, commissioning and acceptance.

3. In terms of management and control integration, most DCS products have incorporated equipment management functions. For example, Hollysys has AMS equipment management software that is compatible with multi-national HART and FF field devices and has been applied in projects. The three-layer structure of ERP/MES/PCS is also constantly improving.

4. Various control systems have been developed due to strong demand for energy conservation, environmental protection, oil fields, gas/oil pipelines, and rail transportation.

5, sensor technology has been developed. Gas sensors Since many factories have adopted the FGS fire gas system, the output is very large at present. For example, Zhengzhou Weisheng Electronic Technology Co., Ltd. currently supplies 3.5 million gas sensors of various types to the world each year. China can now produce a variety of industrial, mining, and civilian gas sensors.

Of course, the flow sensor is a hotspot. In addition to the flowmeter, sonar flowmeters such as SONARtrac can be used to monitor the precise operation of single-phase flow and multiphase flow and slurry or real-time measurement of entrained air/gas, etc. for volumetric gas content monitoring. system. With regard to the mass flow meter, thermal type and Coriolis type, the latter is widely used, and there are also many Coriolis-type domestic manufacturers. Now there are also foreign companies that make the core part of the sensor, such as the Siemens MASS2100DI1.5. /1/16, FC300DN4/1/16, MASS2100DI3-DI40/1/8-2, MC2, etc., to facilitate OEM production for more instrument manufacturers.

In addition, a large number of pressure sensors, except for the process industry, the factory production line, automotive, construction machinery and other areas of strong demand, so many domestic manufacturers. Radar level and laser level instruments have also been developed in level meters, and electrochemical sensor properties and component sensors have also been developed. In addition, discrete sensors related to factory automation are in the ascendant, such as intelligent proximity sensors, valve sensors, intelligent photoelectric sensors, displacement inductive sensors, capacitive sensors, control switches, etc. This field is very broad and remains to be exploited in applications. To serve people's livelihood and safety.
