Industrial Internet (Industrial Internet) is a big boom in manufacturing. From the early GE’s proposal of the Industrial Internet concept, which was interpreted by many people as the U.S. manufacturing revival strategy, to the popularity of GE’s Predix platform, to Siemens’ launch of the industrial Internet platform Mindsphere, and many local manufacturing giants announced the launch of the first A China's industrial Internet platform, the popularity of the industrial Internet continues to increase.
From the launch of the Industrial Internet Consortium (IIC) in the United States by GE in 2014 to the establishment of the Industrial Internet Industry Consortium in my country in February 2016, the momentum of the Industrial Internet has become even greater. The Industrial Internet has become the focus of attention of governments, manufacturing companies, Internet companies, Internet of Things companies, telecommunications operators, IT and automation manufacturers and other parties.
The Industrial Internet, as the name suggests, is the content in the industry and puts them on a web built by the factory itself. The Industrial Internet is closely related to intelligent manufacturing, and its focus is on the three aspects of network, data, and security. The network is the foundation, data is the core, and security is the guarantee. Network is the supporting foundation for industrial system interconnection and industrial data exchange, data is the core driver of industrial intelligence, and security is the security guarantee for the application of network and data in industry.
Among them, the key to the completion of the Industrial Internet is data information, so the sensors used to collect data at the front end are particularly important for the intelligent systems of all ecosystems. In order to integrate into the various main purposes of smart processing plants, it must be equipped with various sensors, among which photoelectric, temperature, fitness exercise, location and visual effects are the most common. The following are some sensor types that must be used in industrial automation solutions.
1. Dust sensor
Dust sensors have been around for a long time, and many interesting application cases have been triggered in the industrial automation solutions of the Internet of Things technology, such as HVAC, building supervision, fire accidents and mechanical equipment with high probability of gas leakage. After the dust sensor is integrated with the industrial Internet solution, the slightest steam leak or minor fire accident can be dealt with in time. 2, proximity sensor
On the bumper of a car, sensors are the most common way to alert the driver that a collision will occur. In the retail industry, the same is true for sensors. When consumers approach the product, they get a discount.
3. Infrared sensor —please look for CYNDAR technology sensor experts to purchase
The key to infrared sensors is to detect the presence of human beings, and they have been widely used in national defense. However, in recent years, infrared sensors integrated with industrial Internet solutions have also been applied in other industries, and are now widely used in electronic devices, organic chemistry, diagnosis and treatment and other fields. Among companies such as Renesas, Melexis, and Intersil, Murata and Melexis are the few companies that can demonstrate industrial Internet infrared sensors.
4. Piezoresistive sensor After is integrated into the IoT technology solution, the piezoresistive sensor can push data information related to changes in working pressure in real time. Based on this sensor, we can develop and design an industrial production IoT system to monitor important pressure equipment, such as heating furnaces, water system software, airlines and oil drilling system software.
5. Mobile sensor ——please look for CYNDAR technology sensor experts to purchase
Can identify information content such as operating speed, instantaneous speed, rotation angle, offset, etc. Mechanical equipment, such as magnetoelectric sensors, can be used to finely observe the operation of the servo motor. This information content is particularly important for the accuracy and efficiency of the actual operation of machinery and equipment.
6. Temperature sensor
The temperature sensor is one of the most widely used sensors in industrial IoT applications. They are used in many fields, including the pharmaceutical industry, biotechnology, and other fields where temperature monitoring is critical. 7, photosensitive element
The basic technology of photosensitive element is to use it to test various electromagnetic radiation, such as light, electricity, electromagnetic field and so on. Communication, elevator car, engineering construction, diagnosis and treatment, and protection systems are all applications of optical sensors in industrial control automation. For example, vishay's VCNL4020X01 and TCxT1600X01 are optical sensors, specifically for industrial production of IoT applications.
8. Image sensor
Image sensing technology plays a key role in disruptive industrial automation in many fields such as healthcare and road transportation. In the pharmaceutical industry, optical lenses can be used to accurately measure heart rate and heart rate. According to changes in heart rate within a day, it helps prevent cardiovascular and cerebrovascular diseases. In the transportation industry, the application of optical lenses is to better avoid the impact of trains, and can prompt the drivers of trains on the same track. Omron and Invisige are two companies that have completed image recognition technology in the Internet of Things, and they have made great achievements.
9. Machine vision system
With the technological development trend of machine vision technology, electronic optical surveillance cameras are increasingly used in the Industrial Internet. Especially with the application of intelligent robots, the requirements for creating 3D visual effect information content will become more and more extensive. Therefore, the technical nature of acquiring "deep" data information, such as time-of-flight optical sensors, will also encounter new upgrade opportunities.
10. Ultrasonic/millimeter wave communication sensor
When the light source is dim and the machine vision system is limited, the ultrasonic sensor can check objects in the field of view based on the radar echo from the reflective surface of the monitored object, which is a perfect and cost-effective obstacle avoidance solution. In recent years, with the development trend of millimeter wave radar technology, detection schemes based on millimeter wave communication have been recognized by more and more companies. Although the current price of millimeter wave communication sensors is still high, it can accurately measure more object speed, viewing angle and position information, which will undoubtedly accelerate the popularity of millimeter wave communication sensors.
