In-depth analysis of the current situation of the domestic sensor market
In addition, Chinese sensors also have new applications in other fields, such as industrial control, environmental protection, facility agriculture, multimedia imaging, and other related sensor applications. Looking back at China's sensor industry, although it is developing rapidly, there are also some disadvantages. For example, in terms of product technology, the industrial foundation is weak, technology and production are disconnected, product technology is low, product types are lacking, and the company's product research and development capabilities are weak.
But on the other hand, the country continues to formulate strategies and policies that are conducive to the development of the sensor industry. The rapid development of the whole system market throughout the year and the continuous promotion of emerging technologies have also become favorable factors for the development of sensor networks.
market capacity
According to China's sensor market status survey and development trend analysis report (2016-2020) released by China Industry Research Network, with the support of the government, my country's sensor technology and its industry have made great progress. The domestic sensor industry has established a production base for sensitive components and sensors in China under the guidance of the "double plus project", namely: accelerating efforts and speeding up development.
At present, there are three major sensor production bases in China. They are: Anhui base mainly builds economy of power and photosensitive scale; Shaanxi base established Shaanxi Sensitive Technology Industry Group Company in February 1990, mainly to establish voltage sensitive, thermal and automotive electronics Scale economy is the main goal; Heilongjiang base mainly establishes gas and humidity sensitive scale economy as the main goal.
At present, my country has more than 1,700 companies engaged in the production and research and development of sensors, of which more than 50 are engaged in the development and production of micro-systems. At the same time, sensors are increasingly being applied to various fields of social development and human life, such as industrial automation, agricultural modernization, aerospace technology, military engineering, robotics, resource development, ocean exploration, environmental monitoring, security, and medical diagnosis. , Transportation, household appliances, etc.
According to statistics, by 2015, the overall market size of my country's Internet of Things will or reach 750 billion yuan, and the sensor industry will directly benefit from it. It is predicted that China's sensor market will develop steadily and rapidly in the next five years. Driven by the substantial growth of the Internet of Things market, China's sensor market is expected to reach about 121.3 billion yuan in 2015.
Market structure
my country’s sensor manufacturers are mainly concentrated in the Yangtze River Delta, and gradually form a regional spatial layout dominated by central cities such as Beijing, Shanghai, Nanjing, Shenzhen, Shenyang and Xi’an.
Yangtze River Delta region: With Shanghai, Wuxi, and Nanjing as the center, a relatively complete sensor production system and industrial supporting facilities including thermal, magnetic, image, weighing, photoelectric, temperature, and gas sensors are gradually formed.
Pearl River Delta Region: Mainly in the central city of Shenzhen, foreign-invested enterprises in nearby small and medium-sized cities form a sensor industry system based on thermal, magnetic, ultrasonic and weighing.
Northeast China: Shenyang, Changchun, Harbin, mainly producing MEMS force sensors, gas sensors, and humidity sensors.
Beijing-Tianjin area: mainly colleges and universities, engaged in the research and development of new sensors, and fill in some fields^. Beijing has established a State Key Laboratory of Micro/Nano. Central China: Mainly in Zhengzhou, Wuhan, and Taiyuan, the model is closely integrated with production, education and research, and the development trend is good in the industries of PTC/NTC thermistor, inductive digital liquid level sensor and gas sensor.
In addition, with the rise of the Internet of Things, the sensor industry has developed rapidly in other regions such as Shaanxi, Sichuan and Shandong.
Facing problems
One is the lack of core technology and basic capabilities, and weak innovation capabilities. There is a huge gap in the high-end aspects of high-precision, high-sensitivity analysis, component analysis, and special applications. Almost 100% of mid-to-high-end sensor products are imported from abroad, and 90% of chips rely on foreign countries. There is a lack of sensors for new principles, new devices and new materials in China. R&D and industrialization capabilities.
Second, common key technologies have not yet truly broken through. There is a big gap in design technology, packaging technology, and equipment technology. There is no set of sensor design software with independent intellectual property rights in China. The reliability of domestic sensors is 1-2 orders of magnitude lower than similar foreign products. Sensor packaging has not yet formed a series, standard and unified interface. The research and development and production of sensor process equipment are monopolized by foreign countries.
Third, the industrial structure is unreasonable, with incomplete varieties, specifications, and series, and low technical indicators. Domestic sensor products often do not form a series, and there is a considerable gap between products in terms of measurement accuracy, temperature characteristics, response time, stability, and reliability. The fourth is weak corporate capabilities. Judging from the current market share and market competitiveness index, foreign-funded enterprises still have a greater advantage.
More than 95% of my country's sensor enterprises are small enterprises, with small scale, weak research and development capabilities, and poor scale efficiency. In view of these problems, how should our country solve them step by step? How to improve comprehensive competitiveness and gradually participate in international competition?
Foreground prediction
The demand for sensors in my country in 2015 could reach 3.2 billion, and the market size could reach about 121.3 billion yuan, which is enough to form a new economic growth point for the sensor industry and the information industry. In addition to industrial automation systems, supporting large-scale key projects, and the application of automotive electronics and home appliances, the applications in modern agriculture, environmental testing and governance, medical and health, and food testing markets are sudden and immeasurable.
In addition, domestic water resources control systems and home appliances are in the development stage from traditional technology to energy saving, emission reduction and technological upgrading. Inverter air conditioners and household vacuum cleaners, washing machines, solar water heaters, especially large central air conditioners have begun to use a lot of pressure Control, temperature adjustment and other systems have opened up a broad space for the application of various sensors in household air conditioners, washing machines, vacuum cleaners, and household water supply systems, and constituted a new market demand and application growth point in China.
