Explore the direction of smart instrumentation development

In recent years, the development of smart instrumentation in China has been particularly rapid, and the types of smart instrumentation on the market have varied. So, what are the development directions of smart instrumentation now? What innovations are needed to achieve a breakthrough?

Multifunctional multifunction is a feature of smart instrumentation. For example, in order to design faster and more complex digital systems, instrument manufacturers have created function generators with functions such as pulse generators, frequency synthesizers, and arbitrary waveform generators. This versatile integrated product not only offers higher performance (eg, accuracy) than dedicated pulse generators and frequency synthesizers, but also provides a better solution for various test functions.

Miniaturized micro-intelligent instruments refer to microelectronics, micro-mechanics, and information technology that are integrated into the production of instruments, making the instrument a small, full-featured intelligent instrument. It can complete signal acquisition, linearization, digital signal processing, control signal output, amplification, interface with other instruments, and human interaction. With the continuous development of micro-electro-mechanical technology, micro-intelligent instruments, their technologies continue to mature, prices continue to decline, so their application areas will continue to expand. It not only has the functions of traditional instruments, but also can play a unique role in the fields of automation technology, aerospace, military, biotechnology, and medical care. For example, it is currently necessary to measure several different parameters of a patient at the same time and perform control of certain parameters. Usually the patient's body is inserted into several tubes, which increases the chance of patient infection. Micro-intelligent instruments can measure multiple parameters at the same time. And it is small and implantable in the human body, making these problems solved.

Artificial intelligence artificial intelligence is a new field of computer applications. It uses computer to simulate human intelligence and is used in robots, medical diagnosis, expert systems, and proof of reasoning. The further development of smart devices will contain certain artificial intelligence, which replaces part of the human brain work, and thus in the visual (graphics and color recognition), hearing (speech recognition and language understanding), thinking (reasoning, judgment, learning and association) Other aspects have a certain ability.

In this way, smart devices can autonomously perform detection or control functions without human intervention. Obviously, the application of artificial intelligence in modern instrumentation allows us not only to solve a class of problems that are difficult to solve with traditional methods, but also to solve the problems that cannot be solved by traditional methods.

Although instrument and meter manufacturers are all working on the development of intelligent electrical instrumentation, domestic companies must achieve breakthroughs in production line technology, measurement chip technology, and material quality. In this way, domestic products can compete with foreign products and become competitive in the market.

Previously, some domestic instrumentation manufacturers have successively introduced electrical test systems with self-diagnosis functions and started to enter the market of smart instrumentation.

However, as a major producer of electrical instrumentation and meters, although the export volume of China's instrumentation products has increased year by year, the export area has continued to expand. However, on the whole, there is still a certain distance from the advanced level in foreign countries, which is mainly manifested in: lack of scientific research investment and low capacity for independent innovation; manufacturing technology, material quality, chip core technology, intensification and concentration of production, and installation size standards Other aspects need to be improved.

According to the investigation by the chief information officer of Jinmo Industrial Control Network, most of the electrical instrument manufacturers in China currently only pay attention to product R&D and ignore the development of production line technology. Some companies' investment is more inclined to product technology than to production line technology, resulting in insufficient investment in hardware equipment. . In this way, the company's automated production level is not high, resulting in product consistency is difficult to guarantee.

It is found that the quality of raw materials used in the production of electrical instrumentation products in China is far from the gap between advanced countries. For example, inductive power meter magnetic bearings, damping magnets and so on. The quality of these original devices determines the service life of electrical instrumentation. Its insulation performance, heat resistance and flame retardancy of the housing are the key factors for ensuring the quality of instrumentation.

In addition, China's core technology for electrical instrumentation, which is the lack of independent development capabilities for measurement chips, lacks innovation with independent intellectual property rights, which is also an important factor hindering the development of the instrumentation industry in China.

As for how to improve the market share and competitiveness of domestic smart electrical instrumentation, it is recommended that domestic instrumentation manufacturers should strengthen technical investment and innovation, and on the basis of introducing, digesting, and absorbing foreign technology, develop production line technology and improve raw material production. Quality, development and production of more integrated chips with independent intellectual property rights, which is the top priority for electric instrument companies.
