The sensor industry urgently needs to break the situation of relying on imports

without perception, intelligence is impossible. Perception is not only the starting point of IOT, but also the starting point of moving towards the era of intelligence and high-quality development. Yang Xueshan, former Vice Minister of the Ministry of industry and information technology, pointed out at the 2018 International (Xuzhou) sensor and IOT Industry Summit recently

since last year, China's IOT market has entered a substantial stage of development. The annual market size exceeded 1trillion yuan, with an annual compound growth rate of more than 25%. The McKinsey report points out that by 2025, the economic benefits brought by IOT will be between $2.7 trillion and $6.2 trillion: cleaning the pendulum bearings, gear rods, pointers, and wires

sensor is the key component of IOT data collection. According to incomplete statistics, China currently has more than 12000 kinds of sensitive elements and sensors with scientific research achievements, technologies and products, and about 7000 kinds of conventional types and varieties. With the development of IOT, the sensor industry will also usher in an explosion. In the next five years, the compound annual growth rate of China's sensor industry will be about 30%, which will be much higher than the global average

however, at a time when sensors usher in broad development space, the vast majority of sensors mainly used in China's market still rely on imports, and the situation that mainstream market products rely on foreign supporting facilities is particularly prominent. Compared with foreign countries, domestic sensors still have a big gap in product quality, process level, production equipment, enterprise scale, market share and comprehensive competitiveness. Compared with the international advanced level, the development of new sensor products lags behind 5 to 10 years, while the industrialized large-scale production technology lags behind 10 to 15 years. Guoyuansheng, vice president of China sensor and IOT industry alliance, said

it is reported that among the nearly 5000 domestic instrument and meter enterprises, more than 1600 produce and manufacture sensitive components and sensors to varying degrees. Science and engineering colleges and universities and scientific research institutions in various provinces and cities in China have developed sensors and produced sensitive components and sensors in small batches to varying degrees. Due to the high proportion of non professional enterprises, sensors are only ancillary products in enterprises, with relatively low output value and insufficient attention. No matter what type of enterprise, the sensor output value of more than 100 million yuan only accounts for 13% of the total number of enterprises. There are less than 200 professional manufacturers with a complete range of products, such as fine ball screw pairs, fine ball screw pair transmission, low friction resistance, high machining precision, which can ensure the coaxiality between upper and lower fixtures, and less than 3% of them

talking about the reasons that restrict the development of China's sensor industry, Guo Yuansheng believes that domestic sensor enterprises lack deep understanding and participation ability of product technology and industrial scale, stretch their biased and one-sided understanding of sensors, often compare with integrated circuit products, technology, process and scale, and lack entrepreneurs with strong strength and strategic vision. Secondly, because the sensor is a multidisciplinary high-tech polymer, there are many kinds of products and small batches, many enterprises but small scale. In addition, domestic sensor enterprises lack core technology, independent intellectual property rights, and high-end talents, especially international leaders

in view of the development status and existing problems of the domestic sensor industry, Guo Yuansheng believes that in the future, sensors should make breakthroughs in two directions: process technology and application. He suggested that the sensor industry should combine regional characteristics and advantages to build a dual ecological industrial chain and form a sensor valley of the international sensor Industrial Park. In 5 to 10 years, more than 100 companies and scientific research institutes will be gathered to form characteristic industrial clusters or bases, involving professional sensor products with outstanding industrial advantages, forming a powerful international industrial park. At the same time, we should create a dual ecological system integrating politics, industry, learning, research, application and service (Natural Ecology), so as to realize the cluster development of sensor industrialization and the revitalization of the industry
