Recently, Chairman Li Jianjun was invited to participate in the evaluation of the core chip technology results of the optical encoders led by the Ministry of Science and Technology, the Ministry of Industry and Information Technology and a research institution of the military, and the vice president of Tsinghua University, and the vice president of the group. Mr. Zhang Heng. Many well-known experts attended this evaluation meeting, and everyone expressed their opinions and gave detailed explanations on this research. High-precision absolute rotary photoelectric encoder, used to detect the speed, position, angle, distance or count of mechanical motion, is a high-end precision equipment integrating optical, electronic and precision machinery. It is widely used in robots. , UAV, CNC machine tools, injection molding machines, rail transit, textiles, medical equipment, printing machinery, etc., is an indispensable high-end product in the process of China's "Industry 4.0" and "Intelligent Manufacturing 2025" ambitious goals, 2017 With an annual usage of 10 million, it has broad application prospects.

The application range of photoelectric encoders is very wide and irreplaceable. CNC machine tools, elevators, injection molding machines, textile machinery and other fields are all industries with particularly strong application of photoelectric encoders. In recent years, with the rapid development of the national economy, encoders have rapidly entered the fields of automobiles, drones, high-end home appliances, and robots. In addition, the application of encoders in the military industry has also developed rapidly, and it is becoming an indispensable product for the modernization of our military. In recent years, the application of encoders in various industries has exploded.

At the meeting, the experts also pointed out a series of problems in this research: Since the photoelectric encoder is a comprehensive high-end precision equipment integrating optical, electronic and precision mechanical technology, it is extremely difficult to manufacture, and its core technology has long been monopolized by foreign companies. Domestic demand has always relied on imports, and supply is completely subject to suppliers. In peacetime, we can also purchase at a high price. If there is a crisis of supply-offs like ZTE and Huawei, it will greatly affect the normal production of the back-end products, and the consequences will be disastrous.

Experts say that in this context, the results of this research will solve these problems and bring a series of economic and social benefits. Including economic scale cost structure, energy saving, annual new output value, annual profit and tax, economic, social, environmental comprehensive benefits, market demand forecasting and promotion and application prospects. This project has opened the curtain of domestic encoder chips replacing imported chips, breaking the long-term monopoly of encoder chips by foreign companies, not only to prove to the world that Chinese companies can also design high-end codes with stable performance and competitive price. In terms of economic efficiency, the chip also brings huge potential benefits to domestic encoder manufacturers.

After the chip passed the test, the foreign supplier heard the news and lowered the sales price of the chip. Our chips have also brought new business opportunities to domestic processing plants, especially the packaging and testing plants, which have potentially solved the employment problems of more people and have enormous social benefits. Today, the evaluation committee listened to the technical report of the project completion unit, gave high recognition to the experts, and put forward many suggestions and suggestions for improvement. This indicates that the technical level has reached the domestic level and has advanced international level in some aspects.
