Today, smart devices are widely used as emerging products in various industries. What are the characteristics of smart devices and what are their future development trends?

Intelligent instruments have a strong integration, of course, this has a close relationship with the development of microelectronics technology. Cpu, memory, timer/counter, parallel and serial interfaces, watchdogs, preamps, even a/d, d/a converters, etc. are all integrated together, combined with computer technology and measurement control technology, intelligent instruments It will happen. This kind of instrument with high integration and multi-technology integration must have many new features.

Compared with traditional instruments, smart instruments have greatly improved automation. The automation of the measurement process can be realized, including keyboard scanning, range selection, switch start closure, data acquisition, transmission and processing, and display printing. Intelligent instrumentation has a strong self-test function, can automatically detect instrument failures, and brings convenience to instrument maintenance. In addition, smart instrumentation also has data processing capabilities that are difficult to match with traditional instruments. Can achieve heavy data processing, and measurement accuracy has also been greatly improved.

Smart devices also have better human-machine dialogue capabilities through keyboards, displays, and more. The operator can implement the command input operation to the instrument, as well as the results of the instrument operation status and measurement data. In addition, smart instruments are equipped with a variety of standard communication interfaces with programmable control capabilities.

After the development of smart instruments in recent years, there has been new development and growth in both technology and types. In the future, smart devices will be more miniaturized, multi-functionalized, artificially intelligentized, networked, and virtualized. They will meet the needs of applications in different fields and promote the development of various industries.

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 Luo Baihui, 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 neglect the development of production line technology. Some companies' investment is more inclined to product technology than to production line technology, leading to investment in hardware equipment. insufficient. In this way, the company's automated production level is not high, resulting in product consistency is difficult to guarantee.
