Liuyang, the first domestic high-end sensor production line, is under construction. The first phase of the project is expected to be completed in March next year, with an annual output value of 5 billion yuan.

It can help robots perceive the outside world. Just as the eyes, nose, ears, and skin function in the human body, the sensor acts as a role in the hardware to receive information from the outside world. It can bring touch, hearing to the robot... Based on networking, the sensor market has developed rapidly in recent years, and has ushered in a major development trend. From mobile phones, watches, cars, to high-speed railways, airplanes, and ships, sensors have penetrated into people's production and life.

At present, the annual demand of my country's sensor market is billions, worth hundreds of billions of yuan. Facing such a huge market, domestic and foreign manufacturers are stepping up research and development to conquer cities. In order to seize the high ground for the development of the intelligent manufacturing industry, Changsha is actively taking action. Yesterday, Hunan Qitai Information Technology Co., Ltd. Sensor Internet of Things Industrial Park started construction in Liuyang Manufacturing Industry Base. The total investment of this project is 1 billion yuan. ) The sensor production line, the first phase of the project is expected to be completed in March next year, with an annual output of 2 million high-end pressure sensors and an annual output value of 5 billion yuan. This is a brand new start for China's sensor industry!

Liuyang builds sensor IoT industrial park

Located on a piece of loess land in Yongan, Liuyang, construction personnel have already moved in. Here, a brand-new sensor Internet of Things industrial park will be built. The total construction area of ​​the project is 23,000 square meters, including the chip main body workshop, sensor packaging workshop and office scientific research complex. One year later, high-end sensors made in Changsha will be sent from here to all parts of the country.

Sensors are called the peripheral nerves of the Internet of Things, and they affect the development of the Internet society. The more developed the society, the higher the demand for sensors. "By 2030, the number of sensors used in the world will increase by leaps and bounds from 3.5 billion in 2013 to more than 100 trillion, and people and the natural environment will be closely connected through sensors."

This is the bold conjecture of Jeremy Rifkin, the author of "The Third Industrial Revolution" and "Zero Marginal Cost Society".

There are currently about 40 countries in the world engaged in sensor research, production and application development, with more than 6000 research and development institutions. Among them, the United States, Japan, Germany, Denmark and other countries are strong, with a wide range of products, wide coverage, and a total market share of more than 60%, and they have the dominant market.

According to industry statistics, the sales of sensitive components and sensors in my country in 2014 exceeded 120 billion yuan; the demand in 2015 was about 65.29 billion, a growth rate of more than 18%, and sales exceeded 130 billion yuan.

At present, my country has more than 1,700 enterprises and institutions engaged in sensor development, production and application, and sensor products have reached 10 categories, 42 subcategories, and more than 6000 varieties.

gap

The output value of a hundred companies is not as good as a foreign company

However, despite the rapid development of my country's sensor market, high-end sensor technology and technology have always been in the hands of foreigners.

Compared with Europe, America and Japan, the domestic industry is backward in all aspects of the industry, and the manufacturing technology and packaging technology are more obvious. In addition, the quality of domestic sensors is unstable, and it is difficult to enter the high-end areas of the industry. On the contrary, foreign sensors have very stable signals after loading the load source, which is well received by the market.

Due to the technological gap, domestic sensor manufacturers mainly produce some low-end sensor products. In the domestic automotive electronics production field, one of the largest sensor markets, 1 billion sensors are needed every year, among which high-end products basically rely on imports, and only some low-end sensors for measuring water temperature and oil temperature have been made domestically.

Competitiveness determines market value. At present, the market share of the top 100 sensor companies in my country is not comparable to that of a leading foreign company. Take pressure sensors as an example. There are thousands of manufacturing companies across the country, but few have exceeded 500 million yuan. The leading sensor company abroad has an annual output value of more than 10 billion U.S. dollars.

Qitai masters the core technology of high-end sensors

Nowadays, coincides with the major adjustment of my country's industrial structure, and the high-end manufacturing industry has also ushered in the spring of development.

After more than 10 years of hard work, Qitai Information has overcome the key core technologies and processes in MEMS sensors, filled the gaps in the country, and enabled the industrialization of high-end sensors with independent intellectual property rights and put them into production in the Liuyang manufacturing industry base.

"Qitai is engaged in the core hardware industry in sensors and is at the highest end of the industry chain. It is similar to the CPU of a computer and also belongs to the category of characteristic integrated circuits." Professor Wang Guoqiu, chairman of Hunan Qitai Information Technology Co., Ltd. According to the introduction, the company will first build the first domestic factory-based non-semiconductor base material MEMS (Micro Electro Mechanical System) sensor production line, and will gradually expand its production to an annual output of more than 10 million high-end pressure sensors. In order to adapt to the development of the Internet of Things, they will also launch digital, network, and smart sensors. After 8 to 10 years of hard work, Qitai Information will become a complete category of Internet of Things sensor professional company, making it the leader of the Chinese industry and enter The first international phalanx.

Relevant experts told reporters that MEMS sensors are new types of sensors manufactured using microelectronics and micromachining technology. Compared with traditional sensors, it has the characteristics of small size, light weight, low cost, low power consumption, high reliability, suitable for mass production, easy integration and realization of intelligence. At the same time, the feature size on the order of micrometers allows it to perform functions that cannot be achieved by some traditional mechanical sensors.

What is a sensor

It is a detection device that can feel the information to be measured, and can transform the detected and felt information into electrical signals or other required forms of information output according to certain rules to meet the needs of information transmission, processing, storage, and Display, record and control requirements. It is the first link to realize automatic detection and automatic control. There are many types of sensors, and there are different applications in different products. Take a simple mobile phone, there are gravity sensors, acceleration sensors, distance sensors, light sensors, three-axis gyroscopes, electronic compasses, etc. In the future, there are more likely to be heat sensors, temperature sensors, humidity sensors, ultraviolet sensors, and pressure. Sensors, etc.
