Accordingto the characteristics of the manufacturing process of its products, themanufacturing industry can be divided into discrete manufacturing and processmanufacturing.

Discretemanufacturing products are often assembled from multiple discrete processes,such as 3C products, automobiles, machinery, etc., and the production processis discrete. The process manufacturing industry is based on a fixed process,through a series of equipment and equipment processing to form a product, theproduction process is highly automated, such as petroleum, chemical, naturalgas, paper and so on.

Theentire production chain involved in discrete manufacturing is very long, andthe various links in the production chain are independent of each other, andthe production capacity is very different. This will cause problems in theconnection of various links and affect the production of the final product. Forexample, in the field of mobile phone manufacturing, sometimes the capacity ofthe new machine cannot be kept up after the release, which may be caused by thelow yield of a certain component in the production chain. Therefore, in thefield of discrete manufacturing, it is very meaningful to provide a unified IoTplatform and connect all aspects of production from the information level.

Specificto the manufacturing process, most of the equipment involved are machine tools.At present, there are some companies in China that explore the direction ofmachine tool information networking, which is a typical application in theindustrial Internet of Things.

Bycollecting and managing information on CNC machine tools and related sensors,you can achieve two values:

Equipmentlevel

Obtainingthe data of the device performance can help the second-hand pricing behind thedevice. In addition, the device fault information code can be obtained, and thedevice fault condition can be known in time to facilitate subsequentmaintenance.

Managementlevel

Theoperator of the workshop can be connected with the production process tofacilitate the management of personnel. This bottom-up data can solve theproblem of relying on the on-site management of the workshop.

Throughthe application of the SaaS level, on the one hand, the status information ofthe equipment can be clearly displayed. On the other hand, some management andcontrol applications can be developed to improve the productivity of themachine tool and the factory. After all the links in the discrete manufacturingchain are connected through the unified Internet of Things platform, it is moreconvenient to manage the overall manufacturing process from a globalperspective.

Thefield of construction machinery is also an industrial application of theindustrial Internet of Things. After installing the IoT access terminal, theengineering machinery equipment can obtain the location and status informationof the equipment in time to improve the equipment usage and managementefficiency. Internet of Things access services generally consist of two parts,the first part is to provide IoT access terminals, and the second part isindustrial IoT big data platform.

TheInternet of Things access terminal mainly includes a positioning module and acommunication module, and generally adopts a GPRS or 4G access mode. Its mainfunction is to obtain the location information of the device, deploy it to theengineering machinery device, and also obtain some state information of thedevice, and transmit the information to the cloud platform in time.

The Internetof Things cloud platform can query the parameters and working conditioninformation of each mechanical equipment in real time and accurately, monitorthe production operation data of the equipment in real time, and push thewarning information when the equipment parameters are abnormal, so as toachieve accurate monitoring of the equipment. At the same time, the platformcan also diagnose and analyze vehicle faults and find fault solutions to assistafter-sales personnel to rush to the site for repairs and improve servicequality.

Inaddition, the Internet of Things platform can also analyze the online quantitydistribution of equipment, equipment operating rate, average working hours ofequipment, and working heat of equipment area. It can predict and analyze theafter-sales service spare parts market to optimize production planning andinventory.

Theabove two are just typical application cases. There are many companies in themarket that are doing industrial IoT platforms, focusing on various segments.Most of the business is concentrated on the data collection and display layer,and some of them involve the second. The layer will do some basic data analysisand management according to the customer's industry characteristics, but thereare very few third and fourth layers.

Thereason is that shallow applications are more versatile, relatively technicallyeasy to implement, and the requirements for the team's technology and industrydepth are not too high; on the other hand, the current level of connectivity isnot up to the industrial level. The application requirements, especially interms of low latency and reliability of the network, result in networkconnections not being able to participate in the industrial system's ownbusiness and production processes.

5G'spossible impact on the Industrial Internet of Things

5Gtechnical features

5G isnot a system designed for a "killer application", but for manyapplication scenarios that are still unknown. The 5G system is designed with atop-down approach. It defines the future application scenarios, then abstractsthe technical requirements from the scenarios, and then finds solutions basedon each specific requirement and develops specific solutions. .

Becausethe requirements of the system are very extensive, the technology of the pastgenerations of communication systems is not suitable for the needs of 5G. Amongthe many preset scenarios of 5G, the technical requirements of 5G aresummarized into three major aspects by the ITU (International TelecommunicationUnion):


■ Ultra high data rate (enhanced mobile bandwidth, eMBB)

Providesextremely high data transfer rates and extreme signal coverage

■ Large connection capacity (large-scale machine type communication,mMTC)

Providingdata connection capabilities for massive devices is the basic requirement ofthe Internet of Things

■ Ultra low latency (ultra reliable low latency communication, uRLLC)

Providesultra-reliable, low-latency communication connectivity services that requireextreme availability and reliability with extremely low latency

IndustrialInternet of Things

Forthe industrial sector, a highly reliable and low-latency communication systemcan be said to be crucial.

Theapplication of industrial Internet of Things has always been stuck in thesurface data collection and display and some management functions extended fromit. It is difficult to refer to the core areas of industrial system control, inwhich the stability and delay of the communication system are not up toRequirements are the main constraints.

Theinvestment in equipment in the industrial field is huge. Whether it is machinetools, production lines or mechanical equipment, the shutdown caused byfailures in the production process often affects the entire production line andeven the entire product delivery cycle.

Toensure stability, the industrial control system is still local, deploying alarge number of hardware and software systems. In this respect, the entirecontrol system is very complicated and has a huge investment. On the otherhand, it also limits the flexibility and scalability of the system. Today, asconsumer demand is changing rapidly, changes in production systems can't keepup with changes in consumer demand, which can lead to missed many newopportunities.

Thecurrent application of mobile communication systems in the field of industrialIoT is not deep, although 4G has greatly improved the speed of the network,which can meet the needs of users to watch video at any time, but thereliability and delay of the network are still A lot of room for improvementdoes not meet the requirements of industrial scenes.

Theapplication of 4G in industrial scenarios is more of a way to upload data tothe cloud in scenarios where real-time requirements are not high. For example,the machine tool in the factory collects data every 5-10 seconds. The data summaryis generally collected into a unified terminal, which is sent by the terminalto the cloud platform through 4G.

Inorder to ensure the stability of data transmission of machine tools, in thefactory, the connection between each machine tool and the unified terminal isgenerally wired. This type of connection is still relatively heavy, and a largenumber of cables will also lead to a complicated internal structure of thefactory. When the performance of the mobile network system is upgraded toreplace the cable, the internal structure complexity of the factory is alsoreduced, making it easier to manage.

In theindustrial field, these requirements for communication systems, 5G technicalstandards can be well met, extremely low delay, ensuring real-time monitoringand control requirements in the industrial field; high reliability networkquality ensures the stability of industrial systems Requirements; largebandwidth can achieve high-definition 3D video, and even AR transmission,greatly improving the operation accuracy in the field of remote control.

5Gapplication in industrial internet of things

At theWorld Mobile Congress held in Shanghai in June 2018, CCTV Financial reportersexperienced the demonstration of 5G smart industrial application scene broughtby China Mobile:

Anexcavator on the site of Shijiazhuang is connected to the cab located in thefield through 5G technology, which can not only work in harsh environments, butalso can be built without artificial.

Visitorscan take real-life driving in the on-site cab, synchronously control theexcavator in Shijiazhuang, and perform excavator front and rear, rotary motionand boom, arm, bucket and excavation loading. The large screen opposite theconsole passes through the scene. Real-time HD video synchronization deliversreal-world scenes and panoramic video effects.

Althoughthis is just a scene demonstration, it represents the potential applicationvalue of 5G in the industrial field and the direction of future applications.At present, 5G commercialization has not yet officially started, and there areno mature 5G application scenarios. However, many research institutionsfocusing on 5G fields are exploring the specific application scenarios of 5G inthe industrial field, and what kind of application can be brought about.commercial value.

Ericssonshared two specific research cases for us, showing us the application of 5Gtechnology, improving industrial efficiency and enhancing business value andsocial value.
