In recent years, with the rapid integration of the new generation of information technology and traditional industries represented by the Internet of things, cloud computing, big data and artificial intelligence, a new round of global technological and industrial revolution is booming, and a series of new production modes, organizational modes and business models are emerging constantly, which is promoting the intelligent transformation of global industrial system. According to the industrial Internet industry economic development report (2020) released by the China Institute of information and communications, it is estimated that the industrial Internet will become one of the most active growth areas in the national economy in 2020. It is estimated that the economic scale of China’s industrial Internet industry will reach 3.1 trillion yuan in the whole year.
There is no doubt that the current “new infrastructure” boom will be an important driving force for the development of China’s industrial Internet industry. “Some experts have further interpreted and classified the seven major fields of” new infrastructure “into information network, transportation network and energy network. However, no matter from what perspective, digitization is the core key element in the layout and construction of” new infrastructure “, which will surely drive a new round of development of its related industries, especially the accelerated development of the industrial Internet of things (iiot), making it the central stage of digital transformation of industrial manufacturing It is an important role in connecting the equipment layer and the network layer, laying a solid foundation for the platform layer, software layer and application layer, and will fully open up the key data flow in the entire industrial system Roger, market manager of industrial automation industry in ADI China, said in a recent media interview.
Accelerating the transition and upgrading of traditional industry to new industry with digital orientation
The industrial field has also been considered as one of the largest application scenarios of the Internet of things. Through the network interconnection, data exchange and system interoperability of industrial resources, the industrial Internet of things can realize the flexible configuration of manufacturing raw materials, the on-demand execution of manufacturing process, the reasonable optimization of manufacturing technology and the rapid adaptation of manufacturing environment, so as to achieve the efficient utilization of resources, and build a new service-driven industrial ecosystem, which itself is closely around digitization 。 With the advancement of digital process, industrial Internet of things can also bring fundamental changes in two aspects for the whole industry, including the digital upgrading of traditional equipment and the new products and business models produced in the process of upgrading.
“In fact, the industrial Internet of things has been upgraded to be digital, networked and intelligent on the basis of traditional industries, of which the core is still digitalization, and networking and intellectualization are the promotion of digitalization.” Yu changtao stressed, “the industrial logic behind the industrial Internet of things is also the integration and application of sensor technology, communication technology and information processing technology. We can well associate its layer structure with ADI products, which will include ADI’s rich and comprehensive sensor series, wired and wireless communication network technology and research based on cloud software algorithm.”
Deployment of industrial Internet of things communication network, gradually moving from wired to diversified combination
The advantage of industrial Internet of things is that it can make better decisions by making full use of the increasing data collected by sensors. In the whole industrial automation system, whether the data can be obtained and transmitted in time depends on the network connection. In order to cope with the increasing amount of data, network technology and manufacturing process flow and method must be constantly improved. Intelligent and interconnected automation environment needs digital connection control system, industrial equipment, production line robots, etc. to create and share information. The communication mode adopted by these machines and the factory communication network deployed are the core of the enterprise, and also the key to promote the realization of industrial Internet of things.
From the perspective of transmission network, the communication mode is divided into wired and wireless, so far the industrial field is still mainly wired communication, wireless communication in some application scenarios as a supplement, industrial Ethernet began to play an increasingly important role. With the development of several decades, industrial Ethernet protocol and topology forms are numerous. More and more industrial automation technology suppliers and manufacturers hope to obtain open communication platform independent of manufacturers. Therefore, the future industrial Internet of things applications must support a variety of common network topologies, such as PROFINET, Ethernet / IP?, EtherCAT?, Powerlink? And other common industrial Ethernet protocols, as well as linear and ring topology and star topology. Yu changtao introduced in detail that the fido5000 series products created by Adi are real-time Ethernet and multi protocol (REM) switching chips with two Ethernet ports. They are programmable IEEE 802.3 10 Mbps / 100 Mbps Ethernet Internet Protocol version 6 (IPv6) and internet protocol version 4 (IPv4) switches, which can support any two or three layer protocols virtually. In addition, it can be connected to any host processor, which allows developers to use their own processors and their preferred development environment.
It is worth mentioning that fido5000 also supports time sensitive network (TSN). In the future, industrial Ethernet Applications Based on TSN will be able to meet the very demanding real-time requirements of motion control or security applications. In an industrial environment, even a millisecond communication delay may have a negative and costly impact on the manufacturer’s product quality, throughput and efficiency. Adin1300, one of the new chronoustm series industrial Ethernet solutions launched by Adi, is further committed to solving the important challenges in deploying Industrial Ethernet connections with low latency and small package size, so as to ensure real-time and reliable industrial communication, thus shortening the industrial Ethernet network cycle time. This is an industrial Ethernet physical layer (PHY) product to help manufacturers meet the communication challenges of key industry 4.0 and smart factories, including data integration, synchronization, terminal connectivity, and system interoperability.
In the field of wired communication, typical fieldbus technology including RS-485 and traditional process control and motor control network. ADI provides a wide range of software configurable IO, field instruments and efficient server drive system based on the development of advanced simulation technology, isolation products and processors. “For example, ADI’s newly launched four channel, software configurable I / O kits, ad74413r and ad74412r, will help develop field configurable remote I / O units, connect traditional field devices to the network, and realize the integration of traditional instruments and high-level Ethernet networks.” Yu changtao gives an example.
In the industrial environment, low-power, stable and reliable wireless sensor network is becoming a supplementary network connection option for more industrial application scenarios due to the convenience of deployment and maintenance. The 2.4GHz smartmesh IP network provided by Adi is an outstanding representative. The most important feature of this network is that the mesh network with high data transmission reliability of 99.999% is realized, and the power consumption is extremely low. At the same time, smartmesh is also a time synchronization network, which can achieve accurate time synchronization of each node, which is convenient for many occasions requiring synchronization. Because of its high reliability, it is very suitable for industrial applications where the network transmission reliability is very high and maintenance free. For smartmesh IP, ADI not only provides high-performance chips and production modules, but also provides customers with a complete set of solutions. Smartmesh network has been applied in global data center, industrial automation, wind power generation, oil pipeline, transportation and other fields.
Intelligent upgrading of industrial equipment starts with accurate “inquiry” production line status
Whether it is industrial Ethernet or wireless sensor network, its greatest value is the landing of industrial applications, including the proliferation of high-quality sensors, reliable connection and data analysis, and the increasing degree of automation of intelligent nodes, the requirements for precise data capture and position tracking of sensors are also increasing. Sensors in the industrial field can be divided into many types, such as the well-known temperature, pressure, flow, liquid level monitoring, etc., which have been widely used for several years. In recent years, more and more mentioned equipment condition based monitoring (CBM) has introduced the technology of vibration monitoring as the core, which can further improve the product performance, production efficiency and added value by collecting and analyzing the vibration state of rotating equipment, which is the most practical economic significance and the most easy application.
For example, people who participate in the maintenance of industrial equipment all know that the vibration emitted by the equipment is very important information, and the health of the equipment can be judged through the vibration, thus the maintenance cost can be greatly reduced. The realization of equipment condition monitoring system depends on a number of series of high-performance MEMS accelerometer products launched by Adi in industrial application. Yu changtao said: “the adxl100x series of single axis accelerometers are optimized for industrial condition monitoring applications. The measurement bandwidth is as high as 50 kHz, and the g value range is as high as ± 100 g. moreover, it has ultra-low noise performance. The main faults in rotating machinery are within the measurement range of adxl100x state monitoring accelerometer. The integrated module product adcmxl3021 also combines high-performance vibration detection with various signal processing functions, which can track vibration signals on many machine platforms and simplify the development cycle of intelligent sensor nodes in the condition monitoring system
ADI team is not only committed to human interpretation of vibration for industrial equipment monitoring, but also to detect abnormal behavior and diagnose from the sound of equipment. The otosense architecture of ADI is a kind of equipment health monitoring system, which supports what we call computer hearing, enables the computer to understand the main indicators of sound and vibration emitted by the equipment, and can identify potential problems in factory machines or automobile engines before the problems become serious. It is worth mentioning that in order to further strengthen the predictive maintenance solution based on condition monitoring, ADI has also acquired test motors, a company specialized in predictive maintenance of motors and generators, and combined ADIF’s original industrial condition monitoring solution technology, as well as otosense’s artificial intelligence platform sensing interpretation software and test The monitoring functions of motors combine to create a more optimized solution to provide more advanced and comprehensive health monitoring for machines by capturing a wider range of potential faults.
Integrated and customized solutions to help industrial IOT application landing
The deployment of “new infrastructure” is speeding up. How to seize the opportunity of industrial IOT landing under the “new infrastructure”? In recent years, with the shortening of product R & D pace and time to market, customers have more and more requirements for semiconductor component suppliers. They are no longer satisfied with only providing corresponding components, but hope for a higher level of support. ADI has been working hard in accordance with this logic in the past few years. For example, based on the traditional advantage products, ADI can not only provide the chip itself, but also integrate the chip into the system level solution based on our understanding of the customer’s system, which greatly reduces the R & D risk and R & D time of customers.
Yu changtao said that the previous industrial condition monitoring module adcmxl3021 provided a full explanation for the systematic design support of ADI. It uses three accelerometers adxl1002, which are widely used in vibration monitoring. At the same time, it also uses a low-power MCU, plus a good and complete tested and verified mechanical structure for modular packaging. As a systematic solution, it perfectly solves the customer’s anxiety of application landing: to select the appropriate sensor chip, there should be corresponding software algorithm support, and at the same time, we must consider the design of mechanical structure. The three adxl1002 in adcmxl3021 can detect the vibration in three directions in X, y and Z axes. The low-power MCU integrates some FFT algorithms, which can transmit some time-domain or frequency-domain data, as well as some original data waveforms. Its entire mechanical structure design is also very small, and through the complete product level certification and verification. This is the common practice of ADI in providing customized and modular solutions for customers.
“Today, perhaps there are still isolated islands of industrial information and insight that we cannot access, but with the acceleration of the” new infrastructure “policy and the increasing popularity of industrial Internet of things deployment, the challenge of traditional industrial transformation and upgrading will turn to how to efficiently collect equipment operation data, ensure its security in the data transmission process, and how to use these data to fully enhance business Industry value. ” Yu stressed, “ADI has deep industrial expertise, technical experience and a wide range of product solutions, which will effectively help you accelerate the transition from traditional industries to future intelligent factories.”
