Internet of Things Technology Helps Make Sensor Market Mature

Sensors, computers, and the Internet are called the three major industries of information technology. With the gradual penetration of information technology into traditional industries, the scope of application of sensors has been greatly broadened and the role has become more and more important. It can be said that the speed of development of the sensor industry determines the development of the Internet of Things industry.

IoT technology promotes the maturity of the sensor market With the rise of emerging industries such as the Internet of Things, the sensor industry has become an important area of ​​competition for hi-tech development in countries around the world. In recent years, China's sensor industry has grown rapidly, and its application model has also matured. However, due to the low industrial scale and poor technological innovation capability, the domestic sensor industry presents a low-end surplus and the market pattern of high-end foreign monopoly. The lag in the development of sensor technology has hindered the smooth progress of domestic strategic emerging industries.

Taking the Internet of Things as an example, in the three areas of the sensing layer, the transport layer, and the application layer, the transport layer and the application layer mainly use computers, communications, and Internet technologies, and the technology path is relatively mature. The sensor layer, which is composed of sensor systems, mainly collects information and data for the Internet of Things and is the basis of the Internet of Things. It can be said that the rapid development of the sensor industry determines the development of the Internet of Things industry.

At present, China has formed a relatively complete sensor industry chain from materials, devices and systems to the network. Great progress has been made in network interfaces, integration of sensor and network communications, and architecture of the Internet of Things system. However, the industry is of a low grade, a small enterprise, and a poor ability to innovate in technology. Many companies only introduce foreign components for processing, and homogeneity is serious. The backward production equipment, process instability and other factors caused by the dispersion of product indicators, poor stability. Imitation products are also less than satisfactory in terms of agility. In areas that are relatively outstanding in R&D, basic development of industrialization has been neglected, and commercial development has lagged behind.

According to statistics, at present, there are about 6,000 sensor products in China, and more than 20,000 in foreign countries, far from meeting the needs of the domestic market. Imports of high-end and mid-range sensors account for 80% of the total, and sensor-chip imports have reached 90%. The domestic production gap is huge. There is a serious shortage of high-tech products such as digitization, intelligence, and miniaturization. The high-end products required by the country's major equipment are mainly imported. The sensors and intelligent instruments required for national security and major projects are often limited by foreign countries.

In the automotive industry, Mercedes-Benz, BMW and other luxury car sensors as many as two or three hundred, some people think that the sensor will be the future of the automotive industry, one of the major venues for competition. In many large-scale equipment and control systems, the number of sensors is even more alarming. The data shows that the demand for the Chinese sensor market will continue to maintain an annual growth rate of 30% in the next five years.

The formation of the advantages of the sensor industry chain In fact, China's sensor industry has formed advantages in some areas. First-generation technology, Yuanwanggu and other companies occupy 90% of the domestic market share in ultra-high frequency RFID products. According to the research report of Xiangcai Securities, the domestic market share of Hanwei's electronic gas sensors is as high as 60%, and the market share of gas detection instruments and meters is 9%.

In many fields of application, although the sensor is an indispensable key device, it can only be attached to a large industrial system, and it is often required to be tailor-made in many fields. In many areas, the market size is not large, so the company Should not blindly pursue the scale.

Secondly, the sensor product development cycle is long and the investment in the early stage is large. Domestic enterprises are generally small in size and weak in technical strength. Many companies rely on their scientific research strength to often lag behind the advanced level in the world. Some of them have even been replaced by more advanced technologies before they even started to be used.

To this end, while strengthening industrial policy guidance and incentives and actively attracting social capital investment, it should also establish public technology platforms in key common areas through financial support.

In addition, in some areas, China's sensor technology and R&D are not lagging behind in the world, and even leading the world in some high-precision aerospace fields, but industrialization is relatively weak, and products lose their competitiveness due to high prices and urgently need to be realized. Low cost commercialization. Sensors are a collection of high-tech products. They have features such as technology intensive, diversity of manufacturing processes, marginality, and comprehensiveness. Industrialization involves a wide range of advances. At present, the country should vigorously promote strategic emerging industries as an opportunity to focus on the needs of sensors for economic restructuring, form a production-learning-research alliance with complementary resources, improve industry product standards, and create conditions for industrialization.
