With the advancement of the global smart network-linked vehicles and the “Made in China 2025†plan, the important position of the sensor technology and sensor industry has become increasingly prominent. As an important part of the perception layer of the Internet of Things, sensors have been widely used in the field of automobile safety configuration, driving assistance, etc., and the industry changes brought about by this are also emerging. On September 12th, the China International Sensor Technology and Application Exhibition was held in conjunction with the Shanghai International Convention and Exhibition Center. For this reason, the reporter interviewed many guests on many issues in the field of domestic automotive sensors.
As we all know, 90% of the automotive industry's innovation comes from automotive electronics innovation. Automotive sensors are front-end systems for information acquisition and analysis. There are generally two types: one is vehicle body sensing, including pressure, flow, acceleration sensors, and gyroscopes, and the other is environment sensing, including lidar, millimeter-wave radar, camera, and infrared Night vision and other intelligent sensing devices. The automotive safety technology has evolved from passive safety technology to active safety technology (smart driving assistance). The sensor system also extends from body electronic sensing to intelligent sensing, and the intelligentization of automobiles brings a huge market increase in smart sensing. At this exhibition, Sensata, Advantech, UST, Minxin Microelectronics and many other well-known domestic and international sensors and Internet of Things companies exhibited. The reporter interviewed Sensata and Advantech on the application and development of automotive sensors.
Reporter: As the global sensor, electrical protector, controller design and manufacturing companies, what are the highlights of this exhibition?
Sensata Greater China & India Market Director of Sensor Products Jia Yongping
Jia Yongping: We mainly do two parts of the product, one is the sensor, the second is the controller. And recently it acquired a company from Schneider Germany, adding a lot of products. Pressure, high temperature, speed, position. We focus on applications that are more difficult to implement. For example, our temperature sensors have no room temperature and only have 300 to 1200 degrees high temperature sensors, which are very technically demanding, difficult to do, and critical. Because the sensor market is very large, only in the area of ​​automotive sensors, 2020 is expected to reach a market size of US$25 billion, and the Chinese market will reach a market size of US$5.5 billion. The entire sensor field should reach more than 100 billion market dollars. Therefore, it is impossible for any one manufacturer to monopolize. Therefore, we are concerned with how to make differentiated products and use our own technological accumulation and technological innovation to do something that others cannot easily enter.
And all of our sensors are produced in China, such as the production bases in Changzhou and Chengdu, Jiangsu. Because we have many large customers in China, we need to provide the nearest products and the best services. Tire pressure sensors on the market may only have a loading rate of around 20%. We expect that 90% will be achieved after the introduction of urban regulations in 2020. Our tire pressure sensors have a market share of more than 50% in the world, and tire pressure sensors have been installed as standard in Europe and North America at 100%. We are designing and manufacturing ourselves, because the most important thing in tire pressure monitoring is the sensor, which is a big advantage for us.
Reporter: It is very important for many consumers to look at the air quality in the car. What solutions do we have?
Advantech’s Embedded Computing Core Group Business Director Hu Zhisheng
Hu Zhisheng: The theme of our press conference is two parts. The left part is the front-end architecture products and services of the Internet of Things, and there is the sensor part. We have an M2.com front-end sensor interface standard, because sensor and processing are not the same, there are various data such as temperature, sensing, gas, carbon dioxide, sensing humidity and so on its interface is not the same, the industry does not A unified standard leads to their respective agreements.
Advantech is based on the global coverage of industrial control. Therefore, we want to combine some leading companies that are more transparent in the front end. For example, Bosch, ST, TI, Freescale, and other leading companies, we lead in the establishment of a front-end The industry standard for sensor interfaces is currently defined as M2.com.
At the same time, we have brought a carbon dioxide sensor that is a carbon dioxide collector that includes temperature and humidity. We also have a sensor for the humidity of the air. In the car in the exhibition basement, including the site and our headquarters, there is a sensor that can be monitored at any time, whether it is carbon dioxide or air temperature, humidity, or a flow meter. The sensor plugs directly into the unified one. The drawbacks of the past are not consistent with ours. You have to use Bosch and use the Internet of Things. There is no way to use it. Therefore, we are determined to push the standards of M2.com in some industrial applications. Now we are advancing to the application of the Internet of Things and we are also collecting the data of individual individuals (including the human body) at the front end and sending them to the back. In addition to the application of this product in the smart home, it can actually be applied to the car's cabin.
Reporter: The sensors exhibited by UST this time are miniature. What technological innovation do we have?
Song Menghua: UST is a supplier of chips to the German automotive industry. Products from chips to sensors are used to convert physical and chemical quantities into electrical signals. The sensors are mainly temperature sensors and gas sensors, where the temperature sensor detection range is from minus 200 degrees to 1050 degrees. Temperature is the most frequently detected physical quantity in the industrial or daily fields. It is worth mentioning here that our company has established a long-term strategic partnership with Shanxi Runyi Auto Parts Technology Co., Ltd. and uses UST chips to produce high-temperature sensors in Yuncheng for the automotive industry. The significance is that this sensor breaks the monopoly of American products. So far, within China, there is only this ethnic enterprise.
What I just mentioned is that we have successfully entered the automotive industry in batches. We are working with the next step of cooperation with Runxi Shanxi and are also air quality sensors used in cars. It is used to detect the air quality outside the vehicle when the outside air When the quality deteriorates and it is harmful to the human body, the external circulation is actively closed. This feature is available in almost 80% of cars in Europe.
Reporter: What applications do you have for your products in the automotive industry?
Suzhou Minxin Microelectronics President Li Gang
Gang Li: One is that we do this kind of car after loading, intake air pipe, and this fuel steam, 5KP, as well as refrigerant sensors, automotive refrigerants, but also organic oil. There are many applications that can be derived from the automotive industry. Like our packaging, we can do DPS, but the packaging is not the same, that is, you can do car suspension. Now on the car, we can't do anything other than the high-range. Basically we have other core technologies, including your packaging and testing. Your chips are your own. I can customize this application for him according to the customer's needs.
