Introduction: In the past year of 2011, it was the first year of the “Twelfth Five-Year Planâ€. It proposed the direction of the transformation of the economic development mode, placed “good†before “fastâ€, and proposed the cultivation and development of strategic new industries and specific The seven major industries have proposed the development of high-end smart manufacturing equipment, etc. In addition to focusing on GDP and other indicators, they have also attached importance 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 become 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 “energy efficient and renewableâ€. "Future Energy" proposed 34 constructions in different fields in the future, including three proposals in the field of automation:
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, JWG14 (Energy Efficiency for Industrial Automation, EEIA Working Group) under IEC/TC65 is mainly responsible for formulating relevant standards for energy efficiency. In 2011, it had held five meetings.
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 besides "Three Watches" (water meters, electricity meters, and gas meters). 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 the industry with scattered detection elements and only needs supervision; the three remote or motion systems, data acquisition systems (SCADA) and remote Terminal unit (RTU), remote I/O, but due to the development of data communication technology, it gradually formed a modern remote measurement and control system (RMCS), its field layer covers RTV, fieldbus, wireless field instrumentation and other related technology products It is also compatible with Internet of Things RFID technology; its monitoring layer covers IEEE803.3, IEEE803.4 and other wired LANs and Internet TCP/IP and OPCUA and other technologies, it is the core of the SCADA software and system referred to today; The management layer is expanded from the central control room of the monitoring layer to the metropolitan area network (MAN, IEEE802.6) and multimedia technology, wireless communication wireless LAN (WLAN, IEEE802.11) wireless personal area network (WPAN, IEEE802.15), broadband Wireless Metropolitan Area Network (WMAN, IEEE802.16) up to the wireless area network mentioned at the beginning of this section (this concerns the low population of geographically dispersed rural areas, mines, etc.) Degree, measurement points, observation points, low-density regions).
At present, domestic automation professionals have made breakthroughs in the application of wireless personal area networks (WPAN, IEEE802.15), especially ZigBee, and the 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 and excellent situation in the 3G era to make remote monitoring and control systems a new growth point. The International Fieldbus Foundation is said to have proposed the work process of ROM (Romotte Operations Management). , May be related to the DEMO demo in the near future, also conveyed a message: The market report of Frost & Sullivan predicts the global SCADA market is 45 billion US dollars.
Instrumentation and Sensors In 2011, China's economy can be regarded as "the scenery is good here." Take last year, Hollysys's annual output value has reached 3 billion yuan; Zhejiang Zhonghua's annual output value reaches 200 million yuan. Yokogawa Instruments' EJA pressure and differential pressure transmitters alone sold more than 200,000 units in 2010, compared with 1 million units sold in 2009. 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 domestic FF field instruments 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. Also equipped with FFBuilder hardware configuration software, FBD control strategy configuration software, alarm and event browsing software, diagnostic software, real-time monitoring software, SAMS equipment management software (this software can connect various intelligences through EDDL and FDT/DTM interface technology Equipment), in addition can realize CIF scene control function in FF technology.
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 foreigners who make the core part as a sensor, such as Siemens' MASS2100DI1.5. /1/16 ", FC300DN4/1/16", MASS2100DI3-DI40/1/8 "-2", MC2, etc., to facilitate more OEM manufacturers of OEM production.
In addition, a large number of pressure sensors have been used in process industries and factory production lines, and automotive, construction machinery and other areas are in great demand. Therefore, there are many domestic manufacturers (OEMs). Radar level and laser level instruments have also been developed in level meters. Electrochemical instruments (PH meters, TOC meters) have also developed physical and compositional (concentration meter) sensors. 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.
