[ Focus on Chemical Machinery Equipment Network ] On November 2, 2021, a special session on the development and application of the Internet of Things and sensor technology of the 2021 World Sensor Conference branch event was successfully held
.
Experts and business representatives at the scene focused on the development trends and opportunities of smart sensing technology, sensors and the Internet of Things, etc.
, and jointly sought the development of smart sensing technology from an innovative perspective, and provided suggestions for building the era of the Internet of Everything and boosting the development of intelligent big data

Chemical machinery equipment network hotspots focus on chemical machinery equipment sensors

In the era of the Internet of Everything, China has built the world's largest NB-IoT network and formed the most active IoT application market
.
The most critical thing in the technology architecture of the Internet of Things is the perception technology to obtain information, that is, sensor technology, which forms the basis of the Internet of Things
.

In our country's existing more than 400 IoT demonstration project systems, various types of sensing technologies and sensor products are widely used
.
Therefore, the development and application of the Internet of Things technology largely depends on the development of the sensor industry
.

　　In the era of accelerated cross-border integration of global information technology and the interconnection of all things, sensors, as an important means of interacting with the external environment and the main source of perceptual information, are regarded as one of the core and foundations that determine the development of the information technology industry in the future
.

　　There are many types of sensors, about 30,000 or more
.
Common types of sensors: a temperature sensor, a humidity sensor, a pressure sensor , a displacement sensor, a flow sensor, a level sensor, a force sensor, an acceleration sensor, a torque sensor or the like
.

　　In the era of the Internet of Everything, sensors are playing an increasingly important role
.
According to a report issued by the Foresight Industry Research Institute, China will usher in a period of rapid development of sensor technology and industry from 2012 to 2020
.
The size of China's sensor market has exceeded 200 billion yuan in 2019; it is expected that in 2021, China's sensor market will reach nearly 300 billion yuan
.

　　However, due to a late start, China is still in a monopoly position in key industries, key technologies, and high value-added applications of sensors
.
According to industry insiders, due to the large number of sensor categories and different technical thresholds, China has a layout in conventional sensors, but high-precision sensors are shortcomings and are facing the problem of "stuck neck"
.

　　First of all, there are a large number of domestic sensor companies.
There are more than 1,700 companies engaged in sensor production and development, but they are not large in scale.
Small companies account for more than 70%, and sensor companies with an annual output value of more than 100 million yuan do not exceed 10%.
Enterprises, with only the leader and no leader, have high thresholds and high costs for upstream and downstream collaboration, and the development of the industry has not yet formed a joint force
.

　　Secondly, from the perspective of the perception layer of the Internet of Things, sensor data collection and transmission standards have not yet been unified.
For downstream application manufacturers, there are certain limitations in the selection and use of sensors, and it also causes certain difficulties in data processing for industry application platforms
.

　　Finally, in terms of high-end sensors, firstly, limited by the level of domestic production and manufacturing, the consistency and stability of the products are not enough; secondly, in the technical research, the mainframe is often taken as the leading role, and the sensor is basically used as a supporting role
.

　　At present, with the opening of the Internet of Things era, various sensors are becoming ubiquitous neurons, and the demand for sensors is beginning to show explosive growth
.

　　Domestic sensor manufacturers, crawling on a long industrial chain with small bodies, are squeezed back and forth, and domestic sensors are living quite hard
.
However, as a very key core component in the Internet of Things and industrial fields, today, with the tide of technology localization, it is imperative for sensors to break through the "stuck neck" technology
.
