Requirements to achieve more sensitive, accurate, faster, and more reliable real-time detection.

What is the current industrial status, market structure and future development prospects of China's sensor industry?

Industry status
The market of Chinese sensors has continued to grow in recent years, with a growth rate of more than 20%. The four major areas of sensor applications are industrial and automotive electronics, communications electronics, and consumer electronics.

In 2012, the overall development of China's sensor industry has gradually expanded, and it is significantly used in the automotive industry, including sensor applications in automotive tires, sensor applications in airbags, sensor applications in chassis systems, sensor applications in engine operation management systems, exhaust gases and Sensor applications and requirements in air quality control systems, sensor applications and requirements in ABS, sensor applications and requirements in vehicle driving safety systems, sensor applications and requirements in automotive anti-theft systems, sensor applications and requirements in engine combustion control systems Sensor applications and requirements in automotive positioning systems, sensor applications and requirements in other automotive systems.

In-depth analysis of the current status of the domestic sensor market
In addition, Chinese sensors have new applications in other fields, such as industrial control, environmental protection, facility agriculture, multimedia imagery, and other sensor-related applications. Looking back at the Chinese sensor industry, although it is developing rapidly, there are also some unfavorable factors. For example, in terms of product technology, the industrial base is weak, technology and production are out of line, product technology level is low, product types are lacking, and enterprise product research and development capabilities are weak.

On the other hand, the state has continuously formulated strategies and policies that are conducive to the development of the sensor industry. The rapid development of the whole machine system market and the continuous promotion of emerging technologies have also become favorable factors for the development of sensor networks.

market capacity
According to the survey and development trend analysis report (2016-2020) of China's sensor market released by China Industrial Research Network, with the support of the government, China's sensor technology and its industry have made great progress. Under the guidance of the “double plus project”, namely: accelerating efforts to accelerate development, the domestic sensor industry has established a production base for sensitive components and sensors in China.

At present, there are three major sensor production bases in China, namely: Anhui base is mainly to establish a force and light-sensitive scale economy; Shaanxi base established Shaanxi Sensitive Technology Industry Group Corporation in February 1990, mainly to establish voltage-sensitive, heat-sensitive, automotive electronics The scale economy is the main goal; the Heilongjiang base mainly establishes the gas and humidity sensitive economies of scale as the main target.

At present, there are more than 1,700 companies engaged in the production and research and development of sensors in China, among which more than 50 are engaged in the research and production of microsystems. At the same time, sensors are increasingly being applied to various areas of social development and human life, such as industrial automation, agricultural modernization, aerospace technology, military engineering, robotics, resource development, ocean exploration, environmental monitoring, security, medical diagnosis. , transportation, household appliances, etc.

According to statistics, by 2015, the overall market size of China's Internet of Things will 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. Under the driving force of the substantial growth of the Internet of Things market, the size of China's sensor market is expected to reach 121.3 billion yuan in 2015.

Market structure
China's sensor manufacturers are mainly concentrated in the Yangtze River Delta region, and gradually form a regional spatial layout dominated by central cities such as Beijing, Shanghai, Nanjing, Shenzhen, Shenyang and Xi'an.

The Yangtze River Delta region: With Shanghai, Wuxi, and Nanjing as the center, it has gradually formed a relatively complete sensor production system and industrial support including heat sensitivity, magnetic sensitivity, image, weighing, photoelectric, temperature, and gas sensitivity.

Pearl River Delta Region: The central city of Shenzhen is mainly composed of foreign-funded enterprises in small and medium-sized cities. The sensor industry system consists of thermal, magnetic, ultrasonic and weighing.

Northeast China: mainly in Shenyang, Changchun and Harbin, mainly producing MEMS force sensitive sensors, gas sensors and humidity sensors.

Beijing-Tianjin region: mainly engaged in the research and development of new sensors, mainly in colleges and universities, filling the domestic gap in some areas. Beijing has established a national micro/nano laboratory. Central region: Zhengzhou, Wuhan, Taiyuan, the close combination of production, study and research, the development of PTC / NTC thermistor, inductive digital liquid level sensor and gas sensor industry.

In addition, the sensor industry is accompanied by the rise of the Internet of Things, and has developed rapidly in other regions such as Shaanxi, Sichuan and Shandong.

Face the problem
First, the core technology and basic capabilities are lacking, and the ability to innovate is weak. The gap between sensors in high-precision, high-sensitivity analysis, component analysis and special applications is huge. Nearly 100% of medium and high-end sensor products are imported from abroad, 90% of chips rely on foreign countries, and there are no new sensors, new devices and new materials in China. R&D and industrialization capabilities.

Second, the common key technologies have not really broken through. There are big gaps 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 that of similar foreign products. The sensor package has not yet formed a series, standard and unified interface. Sensor technology equipment research and development and production is monopolized by foreign countries.

Third, the industrial structure is irrational, the varieties, specifications, and series are incomplete, and the technical indicators are not high. Domestic sensor products often do not form a series, and the products have considerable gaps in measurement accuracy, temperature characteristics, response time, stability, reliability and other indicators. Fourth, the ability of enterprises is weak. From the current market share and market competitiveness index, foreign-funded enterprises still occupy a large advantage.

More than 95% of China's sensor enterprises are small enterprises, with small scale, weak research and development capabilities, and poor scale benefits. In response to these problems, how should China solve it step by step? How to improve its comprehensive competitiveness and gradually participate in international competition?

Forecast
China's sensor demand in 2015 can reach as high as 3.2 billion, and the market size can reach 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, large-scale key projects, automotive electronics, and home appliance applications, applications in modern agriculture, environmental testing and governance, healthcare, and food testing markets are sudden and incalculable.

In addition, domestic water control systems and household appliances are in the development stage from traditional technology to energy saving and technology 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 regulation and other systems, which open up a wide space for the application of various sensors in household air conditioners, washing machines, vacuum cleaners, household water supply systems, etc., constitutes a new market demand and application growth point in China.
