Guo Zhenyu, director of Tencent Cloud's platform department of architecture, gave a speech at "Intelligent Manufacturing and Intelligent Energy".
The following is the full text of the live speech:
Industrial Internet of Things will become the main force of the growth of the Internet of Things
State Grid Corporation proposed two networks in the 2019 report of the two sessions: “Strong Smart Grid” and “Pan-in Power Internet of Things”. The term “ubiquitous power internet of things” first appeared in the report of the State Grid Corporation's two conferences, and the focus of the State Grid's 2019 work in the first place is to promote the deep integration of the power grid and the Internet, and focus on building an energy Internet.
The example of the State Grid fully shows that more and more industries are deeply integrated with the Internet of things through the Internet of things. Today, I would like to share Tencent's thinking on the ubiquitous Internet of things and the product matrix launched. And some application cases in the energy manufacturing industry.
It is an indisputable fact that the rapid development of the Internet of things is already an indisputable fact. According to a report released by IOT, the number of connections to devices is expected to reach 25.1 billion by 2025, of which the number of Internet of things connections in the industry is more than half, judging from the growth rate from 17 to 25 years. The growth rate of the industrial Internet of things is 4.7 times, which is also 2.5 times higher than that of the consumer Internet of things. Therefore, we believe that the industrial Internet of things will become the main growth force of the Internet of things in the future.
In the past, we used to say that the Internet of things makes everything connected. The Internet of everything has many characteristics: the first is mass connection, the second is that the value of the Internet of things mainly comes from the traffic generated by the connection and the value of the application of the Internet of things. The third is centralized data processing, including high delay, high transmission costs and so on. We think that if the development of the Internet of things goes any further, it should be from the Internet of everything to the Alliance of all things. The value of the Internet of things will be more reflected in data analysis and mining.
Everything else has other characteristics: due to the introduction of edge computing, combined with hybrid cloud, IoT data processing is more distributed processing, which can further reduce network latency and provide users with more secure and reliable data local storage and analysis services. To ensure the privacy and security of user data.
Four major issues in the development of industrial Internet of things: cycle, connectivity, safety and standards
In order to develop rapidly in the industrial Internet of things, the "intellectual alliance of all things" is mainly faced with the following four problems:
1Investment and long-term cycle: The Internet of Things terminal development technology stack has more hardware specifications than the Internet development, and the supporting operating systems and middleware are not perfect. The cycle from product development and debugging to business online is long, and the investment is large. Respond quickly to market demand.
2 Connection fragmentation: There are many types of terminal products. The same functions can be realized by different types of products. Individual choices are more personalized, and it is difficult to have a large-scale unified import product like the Internet era. There are differences in communication protocols/standards/addresses between different equipment companies, between different products of the same equipment enterprise, and even between generations of the same product. There are hundreds of commonly used protocols.
3 Security issues: The Internet of Things from the terminal to the cloud to the application, the link of information interaction is long, and the accompanying security risks will increase. Many IoT devices have never considered security during the design or development phase, streaking or using weak passwords. There are also a lot of management, and the overall security issue will become more and more prominent.
4 the standard is not perfect: the standard system of the Internet of things, including the protocol standard of the Internet of things, the security specification standard, the platform access standard and so on, is still not perfect. In the past, different manufacturers are developing according to their own agreements. The development of standards in the field of technology and application also lags behind the needs of the industry.
Tencent Cloud IoT full stack product matrix: service multi-industry different scenarios
On September 30 last year, Tencent announced a restructuring of the company. Tencent CEO Ma Huateng said: this initiative is Tencent's new starting point for the next 20 years. This is a very important strategic upgrade. In the second half of the Internet, it belonged to the industrial Internet. In the first half, Tencent connected people and people, connected users and quality services. In the second half, we will build on this. To help the industry and consumers to form a more open new connection ecology, to achieve the connection ecology of people and equipment, equipment and services.
In response to the four problems of the development of the industrial Internet of Things, we will focus on demand and introduce more ecological partners through the Internet tool to create a scene for energy, industrial manufacturing, power grid, construction, government, automotive and other industries. Service capacity.
In order to realize the above vision, Tencent Cloud continues to enrich the product matrix of the Internet of things, providing full stack Internet of things products for massive global equipment, as well as cross-platform and cross-industry solutions, so that the ability of the Internet of things can help customers in more industries. Let customers focus more on the construction and service of business applications.
In order to solve the problem that the equipment of the Federation of things goes up to the cloud quickly, we have launched one after another:
1 IoT communication IOT Hub provides a secure, stable and efficient IoT communication connection platform.
2 the traffic card service Iot Link, provides the mobile communication access service of the special number section of the Internet of things based on the three major operators (mobile, Unicom, telecommunications).
3 Low-power wide-area IoT service LPWA provides high-capacity, wide-coverage, and highly reliable IoT communication access services (supports LoRaWAN protocol and CLAA protocol).
Recently, four new products have been launched to make up the full stack of IOT product matrices:
1 Internet of things operating system TencentOS tiny. This is a lightweight Internet of things embedded operating system, suitable for a variety of small iot devices, support terminal data fast Tencent Cloud, shield some hardware differences, greatly reduce the terminal development requirements.
2 Internet of Things Development Platform (IoT Explorer). Provide customers with convenient development tools and services to help customers complete device access more efficiently, provide application development and scenario service capabilities, and help customers build IoT applications efficiently and at low cost.
3 Internet of things security service (IoT Trust ID,IoT TID). Provide customers with multi-security level, cross-platform, less resource consumption of Internet of things equipment identity authentication services.
Internet of things market. This is a one-stop Internet of things industrial cooperation service platform, each cooperative developer provides different levels of Internet of things services, jointly promote industrial development.
Subsequent edge computing related services will continue to be launched.
The following is a specific introduction to these four new products.
Development of TencentOS tiny: simplified Network Terminal, Fast Cloud
TencentOS tiny is a lightweight Internet of things real-time operating system independently developed by Tencent. Its functional characteristics are as follows:
1 to provide the most concise RTOS kernel, the resource occupation is very small, the typical LoraWan plus sensor application RAM and ROM occupy only 3KB and 12KB respectively;
2 Provide an efficient power management framework to reduce power consumption for different scenarios;
At the same time, it supports COAP/MQTT/TLS/DTLS and other common Internet of things protocol stacks and components, and integrates Iot Hub SDK, to facilitate users to access Tencent Cloud IoT Hub; quickly.
(4) to provide a reliable security framework to support five levels of security rating schemes;
5 kernel and iot components are highly decoupled, providing good portability and providing automated migration tools;
6 Provides the last screen debugging function of Yunhua, supports OTA differential upgrade, and is convenient for development and debugging.
At present, TencentOS tiny has supported Italian-French semiconductors, Enzipu, Huada Semiconductor, Ruixing Hengfang, national technology and other mainstream manufacturers of a variety of chips and modules, and continues to expand.
TencentOS tiny has been used in some projects and will soon be put on Tencent Cloud's official website for everyone to apply for. At the same time, we are promoting open source related work, hoping to work together with more partners to build IoT ecology.
Tencent Cloud IoT platform: building Internet of things Infrastructure
Internet of things development platform Iot Explorer and IoT hub together, formed Tencent Cloud IoT platform. The Internet of things development platform enables both ends of equipment and industry applications to provide a complete set of platform-level solutions, support complex scene access, secure and stable data communication, visual monitoring, supporting SDK and management flow tools, and so on. It can avoid most of the tedious work, such as self-construction and deployment, operation and maintenance, capacity expansion and so on.
At the same time, the Internet of things development platform also supports the plug-in configuration operation to connect the massive storage service behind Tencent Cloud. Users do not have to purchase and open other cloud services separately. They can use virtual machines and object storage directly in the Internet of things development platform. Database and other rich resources, very simple and convenient.
We hope that customers and developers of Tencent Cloud iot platform can complete the development of industry solutions in one stop, shortening the development cycle and subsequent operating costs.
IoT Device Identity Trust ID: Multiple security levels, cross-platform, and low resource usage
IoT Device Identity (TID) provides customers with IoT device identity authentication services.
First of all, by using one machine, one secret at a time, to ensure that each device, each session has its own separate key. Even if a single device or a single session key is leaked, the security of other devices or sessions can be ensured.
Secondly, the product provides solutions covering different security levels such as hardware and software, supports international mainstream encryption algorithms and supports domestic commercial cryptographic algorithms (SM2, SM3, SM4), including the inspection process and mechanism of Tencent security team reinforcement.
Finally, the end-to-end offline authentication is supported, and the whole process does not need to communicate with the cloud platform. Compared with TLS authentication encryption protocol, handshake data transmission is reduced by 92% and library file size is reduced by 81%. Even embedded MCU with weak computing power has the ability to run.
The first batch of standard safety chips include Fudan Microelectronics, Huada Electronics, Enzipu and related safety chips for Yuanxin, and are expanding.
In addition, Tencent security team Tencent Blade Team has also compiled the Tencent Internet of things Security Technical Specification from the point of view of security vulnerabilities attack and defense. This security specification has made a lot of improvements on the basis of the Internet of things security national standard. It involves the cloud platform security of the Internet of things, the communication and authentication security of the Internet of things, and the security of the terminal of the Internet of things. It can help the manufacturers of the Internet of things to quickly establish a perfect security system of the Internet of things.
Tencent Cloud Internet of Things Market: One-stop Internet of Things Industry Cooperation Service Platform
Faced with the huge prospects and vast market of the Internet of Things, Tencent Cloud has now launched the Internet of Things market. Tencent Cloud will always remain open and look forward to more chip module manufacturers, hardware manufacturers, software service providers, system integrators, solution providers and consulting service providers to join the cloud market through technical cooperation and branding. Promotion, business opportunity sharing and other ways to jointly solve customer needs and share market opportunities. At the same time, government departments are welcome, and entrepreneurs, incubators, developers and channel providers are contributing to the IoT market and seeking solutions.
Application of Tencent Cloud IoT Intelligent Manufacturing Industry
Smart factory, smart charging pile, power operation and maintenance
Finally, three cases of Tencent Cloud iot products in the energy manufacturing industry are shared.
Through the edge cloud interconnection and upgrading of traditional factories, the factory can be transparent and efficient. Collecting monitoring data such as video cameras, workers and asset positioning tags, controllers and meters and reporting them to the cloud IOT platform through the edge gateway, through the big data analysis capabilities of the IOT platform, can greatly improve the predictive maintenance capabilities (including intelligent dispatch , parts turnover, defect traceability, etc.), reduce labor costs, while enhancing product design and optimizing operational efficiency.
Smart charging pile
The rapidly developing new energy charging pile industry is faced with the problems of scattered charging pile, weak power management, poor customer experience and high cost of operation and maintenance. Through IOT platform and Internet of things industry solution support, through intelligent matching location, data analysis and remote reminder reservation, we can optimize the location, reduce the threshold of station construction, and optimize process management. More importantly, the electric quantity of the electric vehicle, the use of the charging pile and the reservation can be associated, the nearest idle charging pile can be automatically distributed, the utilization rate of the charging pile and the customer experience can be improved, and the difference in the cost of high and low peak power consumption can be combined at the same time. Reduce charging operating costs.
Power operation and maintenance
In the power plant, there are a large number of systems and indicators that need to be monitored and managed. In the past, due to equipment suppliers and other reasons, manual inspections and monitoring management are often required, resulting in data monitoring and response delays, and global monitoring data missing.
Through the IOT series products, the data can be collected by the iot terminal, and the data is uploaded to the Tencent cloud iot platform according to the Internet of Things protocol to build an intelligent power operation and maintenance platform. Through the platform, the device can perform online diagnosis, fault prediction and life analysis, real-time monitoring of equipment operation data, multi-dimensional analysis and report presentation, timely response and linkage processing of faults, and greatly improve the intelligent level of power operation and maintenance. .
