What role do sensors play in modern industrial automation?
Sensors are widely used in the field of modern industrial automation. There are many sensors used in the mechanical manufacturing industry, which are used to measure variables in various manufacturing processes.
Compared with other sensors, the temperature and humidity sensor is the most familiar sensor. In addition to the industrial field, it is also widely used in agriculture, chemical industry, civil, scientific research, aerospace and other fields. Humidity and temperature are important environmental factors that affect many places in the industrial field. Many high-precision machining or calibration measurements have high requirements for temperature and humidity, and unsuitable temperature and humidity will affect the precision performance of the product.
In the industrial field, the requirements for temperature and humidity sensors are generally relatively high, which gave birth to industrial temperature and humidity transmitters. Compared with ordinary temperature and humidity sensors, industrial temperature and humidity sensors have more precise measurement and control. A variety of temperature and humidity transmitters can be combined and connected to integrate with other environmental monitoring systems to realize automatic remote monitoring and control.
In addition to transmitters, there is also a temperature and humidity Internet of Things monitoring system to help large factories, mechanical processing, and warehouses realize full temperature and humidity data monitoring, automatically uploading to the cloud platform, with online, storage, statistics, alarms, analysis reports, and remote data transmission functions .
A photoelectric sensor is a device that converts light signals into electrical signals. It can be used to measure light intensity, illuminance, radiation temperature measurement, gas composition analysis, etc.
The pressure sensor is another commonly used sensor besides the temperature and humidity sensor. It can sense the pressure signal and convert the pressure signal into a usable output electrical signal according to a certain rule. It is widely used in various machinery industry production automation, aerospace, petrochemical, electric power and other industries.
Sensors have already penetrated into a wide range of fields such as industry, agriculture, aerospace, heavy industry, chemical industry, civil use, hydropower engineering, scientific research, and electronics. Sensors are not only limited to these types of sensors, but are also widely used in industrial environments such as proximity sensors, position sensors, inductive sensors, vacuum sensors, and flow sensors.
The international standards for agricultural sensors are derived from Israel's scientific and technological contributions. Israel combines the Internet of Things with computer technology to form a precision agriculture system and is widely used. Using mobile phones to remotely manage agricultural facilities improves production efficiency and reduces labor costs. Real-time monitoring is carried out through various agricultural sensors (temperature and humidity sensors, carbon dioxide sensors, light sensors, soil sensors, soil moisture monitors, etc.) to understand the growth of animals and plants and epidemic diseases, and prevent diseases in time. And there are strict cold chain logistics and transportation links, and the Internet of Things is added to the product traceability supervision system, making it more systematic, more integrated, and more scientific.
Agricultural Internet of Things monitoring system, temperature and humidity Internet of Things monitoring system integrates the essence of sensing technology, Internet of Things technology, wireless communication technology, electronic technology, network communication, using cloud platform, big data, cloud computing and other cutting-edge technologies to realize the whole process of information Retrospective. Covers the fields of facility agriculture, food cold chain transportation, vaccine cold chain transportation, factories, laboratories, granaries, tobacco factories, museums, breeding farms, fungus cultivation, warehouses, industry, medicine, and automated integrated monitoring.
There are many things we can learn from the practical results of Israel and the Netherlands. For example, their artificial environment technology is very advanced, creating an artificial ecosystem; drip irrigation water-saving technology is popular and advanced, and Israel’s drip irrigation technology is world-renowned, achieving 95% The above water utilization rate; with the support of the government, farmers use advanced technologies such as satellite identification and data analysis to guide agricultural production activities more scientifically and rationally. Their successful experience has practical guiding significance for agricultural organizations and is worthy of our research and study.
