The concept of edge hasn't appeared for a long time. Many people have generalized it. The scope and explanation are different, and some are even repetitive and contradictory. Today, let everyone learn about the sacred IoT edge.

1. The concept of IoT edge

First, let me introduce what is the edge? Edge computing is data processing at the edge of the network to reduce latency and reduce the demand for cloud computing and data center resources. The edge can be ubiquitous, the most common one, and what everyone can understand best is the actual industrial business site. Edge computing occurs in the smart gateway, where the data is collected and processed. The current market space at the edge is Very imaginative. Consulting companies have predicted the edge market space. By the end of 2023, more than 50% of large enterprises will deploy at least 6 edge computing applications for the Internet of Things or immersive experience. The Chinese market takes the industrial Internet as an example. It is expected to be in 2023. , Industrial manufacturing will have a market space of 7.2 billion U.S. dollars.

Multiple forms of Huawei's edge

Huawei's positioning of the edge is mainly divided into three forms:

• Edge cloud: such as IEC, mainly used for interactive entertainment, online education, media creation
• Edge sites: such as IES, which are generally used for innovative service deployment, traditional services on the cloud, and local data storage
• Edge cloud services: For example, IoT Edge, which is generally used in smart parks, smart transportation, smart manufacturing, etc.
  

The form of HUAWEI CLOUD IoT edge cloud service

Now we are talking about "smart manufacturing", "the next Internet is the industrial Internet", "seize the opportunity of the new digital infrastructure", "the industrial Internet is one of the seven new infrastructures", these new concepts are related to the light edge IoT Edge is inseparable.

The form of IoT edge cloud service is divided into cloud side and edge side. The edge side is mainly divided into Huawei Cloud IoT Edge, which provides data governance, partner plug-ins and operation framework. The operation framework is equivalent to the torso of the octopus tentacle, which is used to shield the underlying system and The difference brought by the hardware, while ensuring the normal operation of the upper-level business, the partner plug-in is equivalent to the suction cup on the tentacles, the entrance to the edge data, and the grasping hand of the edge. The data processing is equivalent to the cerebellum in the tentacles, which processes and transfers data. .

Two, why use plug-in development

In actual manufacturing, customers will always encounter difficult problems:

• The edge side needs to collect data, but there are many types of non-standard equipment, and there is no unified standard agreement.
• The data on the edge side is often tens of thousands of points, and the data is of the order of milliseconds. The data is uploaded to the cloud, which requires extremely high bandwidth and middleware performance.
• In actual production, equipment failure is a common occurrence. Engineers often need to go to the location of the equipment for operation and maintenance, which consumes manpower and material resources, and the timeliness is also very low.
• There are barriers to data, and OEMs have no channel to know the actual usage of EU equipment. To improve and upgrade the equipment, our edge is to solve the pain points of these customers.

The edge can provide a plug-in operating framework, and with the help of the power of the ecology, people who understand the industry know how to solve these pain points with Huawei Cloud IoT. After IoT is added to the ecosystem partner, we can provide data collection capabilities on the customer site, collect industrial equipment according to the protocol, and further route the data to the specified application. Finally, the application business will close the loop. At this time, we have built a plug-in ecosystem and achieved it. The real Internet of Everything.

3. How to integrate plug-in with Huawei Cloud IoT Edge

Plug-in integration solution of HUAWEI CLOUD IoT

HUAWEI CLOUD IoT provides a framework for running plug-ins, and plug-ins developed by partners can run under the framework. I hope that more partners like Sheng Yuancheng will join the IoT ecosystem and solve different customer problems in different fields.

Cooperation between partner Sheng Yuancheng and Huawei Cloud IoT

Sheng Yuancheng is a company that focuses on the equipment industry and is committed to the digital, intelligent, and service-oriented transformation of the equipment industry. It has a deep understanding of the industry, strong research and development capabilities, and 80% of the research and development personnel. The focus on the equipment industry is recognized. Investments in rounds A and A+. Sheng Yuancheng and Huawei began to cooperate in 2016. The main products are Shengyun circle CMS and Shengyun cat SLM. These two products are Sheng Yuancheng's leading products in the equipment industry, and the integration of the IoT edge is the Shengyun circle, which is also the focus of our cooperation. Cloud Shengyuncat integrated IoTDA in 2018 and was selected by HUAWEI CLOUD. This time, it mainly builds the integration of CMS and light edge. The two products can be combined through HUAWEI CLOUD IoT services to carry out the full life cycle of the device. manage.

As shown in the figure below, the CMS software is compatible with multiple protocols and third-party data interfaces, which can realize high-speed millisecond-level collection, data distribution and data uploading to the underlying equipment, and open up the data link between the cloud and the underlying equipment. It has powerful standard module functions. , Intelligent management and control of the production process (monitoring kanbans, alarms, recipes, key parameters, data analysis, quality management) With the high-frequency data support of CMS, SLM can use the powerful data analysis capabilities of the cloud to realize failure analysis and predictive maintenance Wait

How does IoT Edge integrate with CMS

The above picture shows the data flow of Sheng Yuancheng plug-in integrated deployment with Huawei Cloud IoT on the edge side and the architecture after SIoT and IoT edge integration. The field is the edge side is the edge site and field equipment, and the cloud is the middleware of Huawei Cloud IoT and the upper SAAS application. Implementers only need to be in the local environment, use the development version of CMS, and configure the collected point tables and requirements. The standard modules shown are imported into managed IoT edge nodes through remote tools, and the CMS image is pulled and deployed on the IoT edge platform, so that the deployment can be completed quickly in 3 simple steps, and the entire bottom layer can be opened up. Data link from device to cloud.

After the integration of SIoT and Huawei IoT Edge, the project often caused some abnormalities in the software due to system inconsistencies, especially Windows systems. After containerization was deployed to the IoT edge, the problem of difficult software deployment and implementation caused by the system environment was solved. This can be achieved by using the IoT edge. One-click remote deployment to edge nodes at the remote end, which is efficient and stable. After integration, relying on the powerful data processing capabilities of Huawei's IoT edge side, it can connect the full amount of data of the underlying equipment to the cloud with low latency, which largely guarantees the synchronized display of the edge cloud data and reduces latency. After the data is opened up, the IoT edge can be used to efficiently control the nodes and collect a large amount of device information. At the same time, relying on the powerful computing power of the cloud, the algorithm model can be distributed to the edge node, and the actual production process can be optimized to generate huge value. The IoT edge acts as a link, connecting the edge and the cloud, combining the real-time data processing at the edge and the powerful computing capabilities of the cloud to create unlimited value.
