The technical framework is often proposed only to understand the problem, there is no fixed standard, there is no strict boundaries. For example, in the networking part of the product part, there are also components and communication protocols for network connection. Master five technologies IoT products support the popularization of smart home Knowledge of the technical architecture will help master the technology at the overall level. The architecture here is based on the "new technology architecture of the Internet of Things" proposed by Michael Porter and James Hopman, so it is not limited to smart home products but also to other smart products. use. a. product section From a technical point of view, the product includes both hardware and software. The hardware includes: the original physical components, intelligent components (sensors, processors, data storage devices, control devices), networking components (interface, antenna, network connection module, network connection protocol). Software parts include: operating system, software applications, user interaction system. The sensor will be covered in Section 2.2. In addition, in the framework of this book, the product is divided into two parts of technology and experience, which is divided from the user's contact level. The user can touch, see the experience of the user can not be reached, the bottom of the technology, which is introduced in this chapter. b. Internet part Unlike Michael's point of view, networked devices such as gateways and routers are also part of this section, and the network connection protocol is not limited to the communication between the product and the product cloud. It also includes direct communication between the product and the product. In addition, we will cover more details of the communication protocol in section 2.3. c. product cloud part Product cloud consists of three parts: product database, application platform, intelligent application platform. Product database is the bottom of the data storage link, the need to achieve real-time data and historical data storage and management. Application platform is through the use of product databases to achieve product-based smart features, including connectivity with the smart phone APP. Intelligent Application Platform, an intelligent control center with big data analytics technology, including intelligent rule bases for high-level, intelligent management and connection to business systems such as CRM Customer Relationship Management. In addition, the synchronization of data will be described in more detail in Section 2.4. d. Identity and security architecture For the user, including the user's identity authentication, device authorization management. For system administrators, including background system rights management, cloud platform rights management. For example, in the event of technical problems, how to engineer, customer service personnel authorization, and manage their view of the data range and operating authority. e. External data sources External data source, refers to the external data interface, including weather, traffic, location and other information. Among them, including some open data, need to access the system through the API. In addition, it is worth to introduce here SDI <and API two concepts. SDK (Software Development Kit) is a set of tools for developers to open Hair program tools. For example, AndroidSDK is used to develop Android system applications. APIIApplicationProgrammingInterface, that is, the application program interface) is a library that allows programs on the same platform to call other functions. For example, you need to embed a map service on your own website to use the map provider's API. In general, the SDK also includes some APIs. To sum up, it needs to be clear that the technical framework is often proposed only for understanding the problem, and there is no fixed standard nor strict limits. For example, in the networking part of the product part, there are also components and communication protocols for network connection.
When the Double Side Surface Grinding Machine is working, upper and lower grinding discs as well as the planet wheel rotate simultaneously to drive work pieces to do reciprocating planet motion between the two grinding plates.
Xinxiang SKF Machinery Co., Ltd. has focused on researching and developing high-precision grinding technologies of single sided and double sided grinding machines for many years. We hope to share rich process experiences and technological achievements with users.
