Measurement and Control Instrumentation Development Direction of Informatization

Integrate various new technologies, and innovate new weak signal sensitivity, sensing, detection, and fusion technologies based on the research of instrumentation-related types of sensors, components, materials, and technologies, and atomic and molecular level detection technologies. The combination of sample analysis technology, life science in situ, in place, real-time, online, high-sensitivity, high-throughput, highly selective detection technology, create a variety of new detection instrumentation.

Combining the development of system theory and cybernetics, based on the development of on-line analysis and control of industrial automation measurement and control, in-situ analysis and control, high reliability, high performance, and high adaptability, innovative development of industrial automation instrumentation and control systems .

Combining the development of life sciences and human sciences, medical instruments are developed based on the development of health monitoring, early diagnosis and treatment, non-destructive diagnosis, non-invasive and low-impact medical treatment, and precise positioning of treatment technologies for medical diagnosis and treatment; In the field of application, development of various special, fast, automated detection and measurement technologies and special instrumentation.

Industrial automation instrumentation and measurement and control systems and scientific instruments occupy both half of the instrumentation and measurement and control in both the output value and the market, and are the two pillars of the measurement and control instrumentation system.

First, the trend of measurement and control instrumentation development:

Measurement and control instruments face constant improvement in product stability, reliability and adaptability;

Measurement and control instrumentation technical indicators and functions continue to increase;

The first measurement and control instrumentation adopts new scientific research results;

Measurement and control instrumentation high-tech high-volume;

Micro-miniaturization and intelligence of measurement and control instrumentation units are becoming increasingly evident;

It is required that the measurement and control instrumentation unit can be used independently, embedded, and networked;

The scope of instrument measurement and control is extended to three-dimensional and globalized;

The monitoring and control function has been systematically and networked; a large number of portable, handheld and even personalized instruments have been developed.

The characteristics of measurement and control instrumentation are as follows: The information-based automation instrumentation technology of the enterprise includes information acquisition, processing, and application. "Enterprise informatization" is actually the integration and integration of enterprise information. To do this, it is necessary to "simplify", "rule" and "abstract" information with automated and systematic information models in order to make the most effective use of information. This is a basic work in the field of automation instrumentation, and it is also an important means to unify information expression.

Second, measurement and control instrumentation This is the realization of automated instrumentation system can be fully interoperable. Interoperability is hierarchical, and implementation requires a long process. In recent years, the publication of the IEC62424 standard, the expansion of the InTools tool software functions, and the introduction of interoperable standards for the control system and field instrumentation layer are an important landmark in the development.

Third, the security of measurement and control instrumentation The important development of functional safety in recent years is that a large number of measurement and control instruments and meters that have passed functional safety certification have been introduced to the market. In order to gain a favorable position in the competition, almost all instrument manufacturers will conduct functional safety research.

Fourth, system maintenance and instrument diagnosis system maintenance and instrument diagnosis are more and more concerned by users, manufacturers and researchers.

It is divided into four levels: diagnosis of production processes, diagnosis of production equipment, diagnosis of automated control systems, and diagnosis of field instruments.

The diagnosis of production processes does not, in principle, belong to the category of automation instruments, but the exchange of diagnostic information involves automated instrumentation systems. For the monitoring of production equipment, diagnostic instrumentation systems have introduced new products. The diagnosis of the automatic control system is usually a module or a function of the equipment management software in the control system, which is responsible for the real-time diagnosis and predictive maintenance of the control system itself and the field instruments. Field instrumentation is difficult to diagnose. The maintenance period is determined by the loss of the smart meter or fixed time.

V. Wireless communication technology of measurement and control instrumentation The rapid development of industrial wireless communication technology is a prominent highlight in the field of automation instrumentation. Its characteristics are: diversification of technical solutions, rapid increase in participants, and establishment of a professional organization. The introduction of a variety of wireless demonstration systems and measurement instrument prototypes will become the focus of major automation instrument exhibitions around the world.

VI. Control Network of Measurement and Control Instrumentation Network control measurement and network instrumentation will be the focus of automation instrument development in the next few years. The direction of development is to significantly increase the speed, simplify the complexity of installation and commissioning, expand wireless functions, and develop network technologies.

VII. Standardization of measurement and control instrumentation The standardization of production has played an important role in the history of automation instrument development. In the future, it will play a major role in catching up with the world level for instrument products in China. In the new economic era, there are a large number of information interface standards. Its common feature is that there are many standardized solutions at the same level of technology. Now we can set standards for high-tech new products and completely change the concept of standardization.
