ABB invented and manufactured many products and technologies, including three-phase transmission system, world-class self-cooled transformer, HVDC transmission technology and an electric industrial robot, and took the lead in putting them into commercial application. ABB has a * * * product line, including a full range of power transformers and distribution transformers, high, medium and low voltage switchgear products, AC and DC power transmission and distribution systems, power automation systems, various measuring equipment and sensors, real-time control and optimization systems, robot software and hardware and simulation systems, energy-saving motors and transmission systems, power quality, conversion and synchronization systems, and fuse and switch devices to protect the safety of power systems. These products have been used in industry, commerce, electricity and public utilities.

In the control system, instruments and meters are its constituent elements, and its technical progress follows 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.
