Breaking the "sensing" bottleneck of the Internet of Things to create an international sensor valley
Recently, a US-Chinese scientist, Song Jinhui, realized the world's first 50-nanometer ultra-high-resolution digital image sensor, which has attracted wide attention in the industry. It breaks the industry limit of 1 micron pixel image sensor in this field, and attracts international electronics, military, aerospace, medical, laser, information storage technology and related departments.
The Internet of Things continues to grow, the importance of sensors is increasing, and demand is rising. The sensor is the foundation of the Internet of Things and is in the upstream of the industrial chain. It has benefited a lot from the beginning of the development of the Internet of Things. At the same time, the sensor is in the tower of the Internet of Things pyramid, which will be the most demanding and basic part of the entire IoT industry.
Sensors have become the bottleneck of China's Internet of Things development, and the requirements for localization are urgent: China's sensor industry is lagging behind, domestic sensor demand, especially high-end demand is heavily dependent on imports, and the localization gap is huge. Currently, sensor imports account for 80%, and sensor chip imports account for Up to 90%.
Demand growth
In recent years, the global sensor industry has developed into a blowout situation. The development of 10 key areas such as the new generation of information technology industry, high-end CNC machine tools and robots are closely related to sensors. It is estimated that in the next five years, the global compound growth rate of all sensor markets in the world will exceed 10%, and it is still a high-growth industry. In 2015, the global market for sensitive components and sensors will reach $177 billion.
Smart lighting can turn on or off the power of the lamp by sensing thermal energy, automatically sensing the user's access, so as to achieve real energy savings.
The humidity sensor is applied to the wiper of the car. If it is raining or liquid splashes on the window, the sensor can automatically activate the wiper to discharge the liquid on the windshield.
For the part of urban traffic, the smart meter can accept coins, credit cards, and proximity wireless smart phones to pay for parking. When the public finds a parking space, they no longer need to rush to put the coin into the parking meter. These smart meters are also equipped with vehicle sensors that transmit messages in the app so that drivers don't have to take a circle to find a parking space.
Guo Yuansheng expects that the demand for optical bio-signal sensors will grow rapidly. Consumers began to pay attention to their physical health. The simple step-and-sleep monitoring function in general wearable devices has long been unable to meet the needs of users. It measures heart rate, blood pressure and blood by illuminating the skin with different wavelengths of light-emitting diodes (LEDs). Physiological values ​​such as oxygen are the development trend of wearable devices.
Environmental sensing will also be the next wave of sensor development trends. "In recent years, consumers' demand for environmental quality around their lives has risen, which will drive the demand for a wave of environmental sensors to rise," said Guo Yuansheng.
Create an international sensor valley
After years of development, China's sensor industry regional layout has formed five regions that are relatively concentrated: the Yangtze River Delta region, the Pearl River Delta region, the Jinjing region, the Northeast region and the central region. Guo Yuansheng suggested that on the basis of existing domestic and foreign enterprises, talents, technology, market and other resources, combined with location advantages and policy advantages, integrate domestic and foreign product testing, technical standards, market docking platform, product technology development, international exchange and collaboration, The existing conditions of public service such as talent introduction and training, through the development and promotion of politics, production, learning, research, use and service six-dimensional integration, create a “double ecological†industrial chain with good natural environment and superior industrial ecological environment. In 5-10 years, it will become an international sensor industry park, namely China's “Sensor Valleyâ€, which will form an industrial agglomeration effect and promote the development and improvement of the overall level of the domestic sensor industry.
It is understood that at present, Hangzhou, Guangzhou, Chongqing, Changzhou, Kunshan, Zhangjiagang, Huzhou, Shanghai, Wuhan, Tianjin, Nanjing, Wuxi, Jinan and other cities are willing to provide corresponding resources to implement planning goals. The Electronic Components Industry Development Research Center of the Ministry of Industry and Information Technology, the German AMA Association, and the Japan MCPC Computer User Association form an alliance to participate in the construction of the Sensation Valley. The Silicon Valley High-Tech Enterprise Alliance and the Japan Sensor Association participated in the construction of the assistance; China Discrete Manufacturing Industry Alliance, Home Appliances Association, and Equipment The Manufacturing Association and the Automotive Electronics Association participated in the construction of a market docking and communication platform; the University of Coburg, Tsinghua University, the University of Electronic Science and Technology, and the China Metrology Institute established a key sensor laboratory to provide talent training, new technology, and process research and development support.
Industry trend "clusterization"
The prospects are certainly promising, and the real dilemma still exists.
Academician Chen Junliang of the two academies once said: "The Internet of Things era is coming to us. The vision of the Internet of Everything and the intelligent society that people have imagined in the past is now becoming a reality with the development of sensing technology. But now the development of the Internet of Things The biggest bottleneck is still reflected in the sensor."
"Domestic sensors have few types of production and low output, which is the biggest shortcoming in the development of the Internet of Things." Chen Junliang said.
Wang Yongtao, CEO of Beijing Aikei Rui, believes that the main problems facing the sensor industry at present are: the industrial links are scattered, and the effective development and promotion mechanism has not yet been established. "Many companies have prejudice and one-sided understanding of sensors, often compared with integrated circuit products, technologies, and processes; lack of entrepreneurs with strong strengths, large enterprises do not look up, small enterprises can not afford, resources are difficult to integrate."
"Because of the high technical content of sensors, the industry characteristics of products with multiple varieties and small batches, enterprises are also accustomed to small-scale and small-scale operation, lacking a large and specialized awareness, resulting in a large number of industrial enterprises and small scale, which is completely different from foreign countries. Wang Yongtao said, "On the other hand, the sensor industry is in short supply of professionals such as technology development and industrialization development."
How to break through the bottleneck that has long plagued the development of the sensor industry? Guo Yuansheng's suggestion is to form a “double ecological†industrial environment through system construction and mechanism innovation, to create an international industrial environment, to introduce and concentrate various international resources, and to build a complete sensor industry chain, so that the sensor industry is “clusterizedâ€. "Development path.
"To build China's 'sensing valley'." Guo Yuansheng said. It is necessary to establish a natural ecological park with people-oriented, beautiful environment, energy saving and emission reduction, complete hardware environment and public service facilities; it is also necessary to build a complete upstream and downstream industrial chain, reasonable mutual ratio, short-distance docking of market services, complete public services, and talent advantages. Outstanding industrial ecological park.
The establishment of Sensing Valley must also be multi-party cooperation and state support. Guo Yuansheng believes that only in this way can the sensor industry adapt to the new normal of global information technology: regional penetration, industrial integration, technological innovation and structural transformation. 
This valve consists of a hollow, moveable floating piston pressed against a stationary solid seat, and can use the working fluid or an external pressure source to seal the valve. This open/closed valve has a novel balanced piston so it can be designed to always seat with the same amount of force, allowing the use of metal-to-metal seats as well as soft seats. Additionally, this valve design, even when used with large, high-pressure applications, does not require large conventional valve actuators, and the valve stem itself is eliminated. Actuation is achieved with the use of small, simple solenoid or hand valves. This design also eliminates the need for many seals used with existing ball valve and globe valve designs, which also commonly cause failure. Coupled with the elimination of the valve stem and conventional valve actuator, this valve design reduces downtime and maintenance costs, while increasing valve reliability and seat life.
