CB 8013BSE042245R1ABB's control system in the 21st century will be a combination of network and control. The research on Networked Control System (NCS) has become one of the frontier topics in the field of automation. As the communication network is embedded in the control system as a system link, it greatly enriches the industrial control technology and means, and makes great changes in the system structure, control method and man-machine cooperation method between the automation system and the industrial control system. At the same time, it also brings some new problems, such as the coupling of control and communication, time delay, information scheduling method, distributed control mode and fault burst.

As its constituent elements, CB801 3BSE042245R1 ABB instruments and meters have developed with the development of control system technology. At present, the control theory has developed to a new stage of intelligent control, and the intelligentization of automatic instruments and meters has become inevitable.

The intellectualization of instruments and meters is mainly attributed to the development and application of microprocessor and artificial intelligence technology.

For example, using intelligent technologies such as neural network, genetic algorithm, evolutionary computation and chaos control, instruments and meters can achieve high speed, high efficiency, multi-function and high flexibility.

Another example is the use of fuzzy reasoning technology of fuzzy rules to make various types of fuzzy decisions on various fuzzy relations of things.

For another example, using software to realize signal filtering, such as fast Fourier transform, short-time Fourier transform and wavelet transform, is an effective way to simplify hardware, improve signal-to-noise ratio and improve sensor dynamic characteristics.

For example, make full use of the powerful self-learning, self-adaptation and self-organization capabilities of artificial neural network technology, the functions of association and memory, and the black-box mapping characteristics between input and output of nonlinear complex relationships.

At present, the basic industries such as instruments, meters and sensors are the weakest and most in need of development in the field of intelligence in China. With the rapid development of science and technology and the continuous improvement of automation, China's instrument industry will also undergo new changes and obtain new development. High-tech instrumentation products, especially intelligence, will become the mainstream of instrumentation technology and industry in the future.
