Overall quality sensor industry in China is uneven, its self-sufficiency rate of high-end products. In the next few years, under the impetus of the policy, the sensors will have broad application prospects.
High speed development and four big trouble Sensors to overcome difficult to development
Sensor is very important in the field of industrial automation, plays a connection to physical world and the control system to provide information of important role. In industrial process control, computer technology is already relatively mature, need to collect information is increasing, the production process requires a large number of various types of sensors, such as pressure sensor, a thermal sensor, light sensor, gas sensor, moisture sensor and magnetic sensor, etc., to a large number of physical and chemical parameters of non-electricity into electrical signal control information, in order to meet the various demand for the development of industrial process automation and intelligent.
Sustained growth in recent years, the market has been the sensor, the growth rate of more than 20%, mainly used in industrial and automotive electronic products, communications electronics, consumer electronics products are the four major fields of specialized equipment. At the same time, with the development of technology, the sensor is increasingly applied to various fields of social development and human life. Such as industrial automation, agricultural modernization, space technology, military engineering, robotics, resource development, Marine exploration, medical diagnosis, environmental monitoring, security, transportation, household appliances, etc.
In addition, with the support of the government, the sensor technology and its industry in China has made great progress, especially in the area of sensor production base created no small achievement. The current domestic production base, there are three sensors are: anhui base, main is to establish a force, photosensitive scale economy; Shaanxi sensitive technology industry group co., LTD., mainly is to establish a voltage sensitivity, thermal, automobile electronic scale economy as the main target; Heilongjiang base mainly gas, humidity sensitive scale economy as the main target.
In China's rapid development of sensor at the same time, the industry still exists some negative factors.
One is the lack of core technology, innovation ability weak. Sensors in high precision, high sensitivity analysis, composition analysis and special application of high-end gap is huge, high-grade sensor products are almost 100% imported from abroad, 90% chip dependence on foreign, domestic lack of sensor of new principles, new devices and new material of r&d and industrialization capability.
2 it is the key technology has not yet been breakthrough. Design technology, packaging technology, equipment, technology is a great disparity, etc. Domestic, there is no a set of software with independent intellectual property rights of the sensor design, domestic sensor reliability is lower than similar foreign products 1-2 orders of magnitude, sensor encapsulation has not yet formed series, standard and unified interface. Sensor research and development and production process equipment by foreign monopoly.
Three is unreasonable industrial structure, varieties, specifications, the series is not complete, technical indicators is not high. Domestic sensor products tend to not form series, the product in the measurement precision, temperature characteristic and response time, stability, reliability and other indicators and foreign also has a considerable gap.
Four is the enterprise ability. More than 95% of the sensor in our country enterprise belong to small businesses, small scale, research and development ability weak, poor economies of scale. From the current market share and market competitiveness index, foreign companies still occupy a larger advantage.
Aiming at the status quo, countries are conducive to the development of sensor industry strategy and policy, and the year of the rapid development of the whole machine system market and emerging technologies push also become positive factors in the development of sensor network. According to understand, to 2015, China has reached 750 billion yuan, the Internet of the overall market size and sensor industry will directly benefit from it.
In the future five years, sensor market will be steady and rapid development in our country. Especially under the power of the Internet of things market scale growth, in 2016 China's sensor size of the market is expected to reach 121.3 billion yuan. In addition to industrial automation systems, large-scale key projects supporting, automotive electronics, and the application of electrical home appliances products, in the modern agriculture, health care, environmental detection and governance as well as food market in the field of application will also be incalculable.
