Industrial intelligence is inseparable
The reason why we can feel the changes in the outside world is because we have five senses and touch. With the advent of the era of the Internet of things, "interconnection of all things" has become a basic requirement. In order to realize the perception of objects, sensors have to be used. Just as people have tens of millions of tactile nerves, there are many kinds of sensors. There are nearly 10000 kinds of sensors. In the future, sensors will be another trillion market with great potential.
China's sensors started relatively late. The development of high-end sensors lags behind developed countries such as Europe, America, Japan and South Korea. With the rapid development of domestic informatization, and the country lists sensor technology as a key breakthrough field, China's sensors have developed rapidly in recent years.
The sensor industry is a technology and capital intensive industry. In the early stage, China's sensor business failed to receive high attention and developed slowly, so it is difficult to form economies of scale. However, in recent years, with the enhancement of independent innovation ability of domestic enterprises and the support of national policies, the import substitution of sensors in China is accelerating.
The development of industrial intelligence in China is inseparable from sensors. Domestic sensors are accelerating to replace imported sensors
The process of intelligence is inseparable from sensors
Sensor is a basic product in electronic information equipment manufacturing industry and a special component in the new electronic components. As a promising high-tech industry, sensors have high technical content, good economic benefits and strong penetration ability. They have great development potential in the fields of industrial production, smart home, environmental protection and so on.
The key of intelligent manufacturing technology is to enable the products to be effectively identified, positioned and traced by the automatic production line, so that the intelligent machines and equipment on the production line can be manufactured and processed according to the customization requirements of different products. Specifically, micro intelligent devices such as intelligent sensors, processors, information memory and wireless communicator are added to various products to be processed.
With the advent of the intelligent era, sensors become more and more irreplaceable. Sensors have great potential in industrial production, smart home, environmental protection and so on, and with the gradual arrival of the intelligent era, sensors will become more irreplaceable. With the development of the information age, sensors are more widely used in various products. Miniaturized, digital and intelligent sensors have been popularized rapidly, which has changed our way of life. Sensors provide objects with senses such as touch, taste and smell. They have great potential in industrial production, smart home, environmental protection and so on.
What are the opportunities for domestic sensors?
At present, the domestic sensor industry is in a critical period of upgrading. Sensors need more miniature, intelligent, networked, systematic and functional products. Sensor technology has generally gone through three stages of development, from structural sensors to solid sensors. Now it is intelligent sensors. However, there is still a big gap in China's technology compared with foreign countries. The urgent task is to narrow this gap.
The industrial scale is growing. The scale of the global sensor market has maintained stable and rapid growth for many years. According to the prediction of the Ministry of industry and information technology, the scale of China's sensor market will reach 261 billion yuan by 2018, with an annual compound growth rate of about 29.56%.
It is proposed in the three-year action guide for the smart sensor industry that by 2019, China's smart sensor industry will make obvious breakthroughs, the industrial ecology will be relatively perfect, and a number of international advanced enterprises with strong innovation ability and obvious competitive advantage have emerged. The technical level has been steadily improved, the product structure has been continuously optimized, and the supply capacity has been effectively improved. At present, there are 5 enterprises with main business income exceeding 1 billion yuan and 20 enterprises with main business income exceeding 100 million yuan.
The ability to innovate has been significantly enhanced. Build an intelligent sensor Innovation Center; Simulation, design, MEMS process, wafer level packaging and personalized testing technology have reached the international level; The software and hardware integration capabilities covering analog and digital / digital and analog conversion (AD / DA), application specific integrated circuits (ASIC), software algorithms, etc. of intelligent sensors have increased significantly; The number of smart sensor patent applications has increased steadily, forming a preliminary layout in key areas such as new sensitive materials, low-power design, feedback control and safety mechanism; The intelligence level of metal, ceramic, optical fiber and other non semiconductor sensors has been rapidly improved.
Recently, Wang Wen research group of ultrasonic technology center of Institute of acoustics, Chinese Academy of Sciences has successfully developed a new current sensor with high sensitivity, fast response and low hysteresis error. Compared with the prior art, saw current sensor shows the advantages of miniaturization, strong anti-interference ability, good linearity and low power consumption. It has application prospects in smart grid line detection, power supply safety early warning and rescue in power metallurgy and rail transit, and power supply relay protection in industrial automation.
The ecological system is basically perfect. The carrying capacity and technical level of intelligent sensor public service platform are rising steadily; The supply capacity of thin film sensitive materials for MEMS such as aluminum nitride (AlN) and lead zirconate titanate (PZT) has been continuously enhanced; The performance of major equipment such as coating machine, lithography machine, deep silicon etching machine, wafer bonding machine and large-scale high-precision testing machine has been rapidly improved. Industrial chain coordination has been continuously strengthened, and strong system scheme ability has been formed in key application fields.
At present, according to the operation of several major sensor enterprises in the industry, as the core and foundation of Internet of things technology, intelligent manufacturing technology and even artificial intelligence technology, the application of various types of sensors is growing rapidly, and the revenue and profit growth are higher than the overall level of the industry. There is no doubt about the development prospect of sensors.
Sensor is a key device with high technical content, but it needs to depend on other systems and specific applications, so it is difficult to form a large output value and scale; Therefore, most of the current industrial sensor enterprises are taking sensor technology as the core, expanding machine products and system integration, and forming industry solution platform technology.
Because the key processes of sensor chips (especially high-precision pressure sensor chips) are controlled by others, most sensor enterprises in the industry actually compensate and package applications after purchasing sensor chips or modules, forming end products and system integration. It is very obvious that the design and application of industry enterprises are strong, and the key processes of core components are weak in the middle.
In addition to paying attention to the key processes of the core components of the sensor, the trends of chip, miniaturization, intelligence and low cost of the sensor, the deep understanding and grasp of the application industry and scenarios, and the extension of data acquisition and integrated application are also common problems that should be paid attention to.
