Learn IoT technology and embrace the future of IoT

In recent years, the Internet of Things technology has been applied into smart homes, shared bicycles, and smart cities, which has shown explosive growth. So what is the Internet of Things? What are the levels of the Internet of Things? Living in an intelligent society, how can we catch up with the technological trend of the times and embrace the world of Internet of Things? In the following parts, we will answer these questions one by one.

Internet of Things and Sandwich

Everyone knows that the Internet of Things is an important part in the new generation of information technology. Its English name is "The Internet of things". As the name implies, "The Internet of Things connects with the Internet of things." The level of the Internet of Things (IoT) is usually divided into four layers, including application, platform, network, and perception. IoT is like a sandwich. The bottom layer is perception, and the middle layer is the platform and network. While the top layer is the application.

There are thousands of types of IoT terminal devices. As they use different communication protocols, so they just like sandwiches with various food materials. The IoT platform should support diversified device access protocols so that terminal devices can quickly access the IoT platform, and reduce the difficulty of integration for terminal device manufacturers.

Huawei Ocean Connect IoT Platform

Huawei Ocean Connect IoT platform provides full-stack platform services, including connection management, device management, and application enablement. In the process of large-scale commercial use, combined with the operator's network, Huawei aims to build "cloud-network synergy" for showing the advantages of NB-IoT and 5G networks. In addition, Huawei Ocean Connect IoT platform provides standardized terminal access for various industries. While the terminal is plug and play. It supports the rich protocol adaptation, presets terminal access plug-ins, and completes terminal and platform integration within a few hours.

Huawei Lite OS System

The bottom layer is the perception layer, used for information collection and signal processing, just like the skin and facial features of the Internet of Things. For example, if your hands are scalded by boiling water, you have to ask your brain how to act. When you retract it, your hands will become pig's feet.

Every IoT device usually has a small amount of computing power. Compared with computers or smart phones, the main function of IoT devices is not computing. They usually only have a small micro-controller (MCU) development board connected to a device designed for a specific purpose.

IoT devices have their own programming environment. But due to the limitations of the device's limited computing power, it is impossible for IoT devices to run traditional operating systems or development tools.

Huawei Lite OS is a lightweight operating system based on a real-time kernel developed by Huawei for the Internet of Things. Lite OS is a lightweight IoT operating system with a minimum kernel size of only 10KB, which has the advantages of fast start-up and low power consumption.

The Open CPU architecture is designed for the Lite OS small kernel architecture to meet the demand for limited hardware resources. Through the Open CPU architecture that combines MCU and communication modules, it will significantly reduce the size and cost of the terminal.

Huawei IoT Certificate

Huawei has now launched HCIA-IoT certificate and HCIP-IoT Developer certificate. And it will upgrade the two certified products this year.

HCIA-IoT V2.0 (Huawei Certificated Internet of Things Engineer) is positioned at the popularization of basic knowledge of the Internet of Things, the delivery of applications and solutions in the Internet of Things industry, the construction of operation and maintenance and secondary development capabilities, which is based on Huawei Internet of Things solution architecture, assessment and certificate. That are designed to promote the construction of the Internet of Things ecosystem and the cultivation of talents. Compared with V1.0, HCIA-IoT V2.0 pays more attention to experimental links, increasing the proportion of experiments to 50% of the total duration of the course. And it optimize the original experimental content to improve the practice. Meanwhile, it adds the smart home and other communication methods to achieve end cloud Interoperable experiments for further enriching the experimental content.

HCIP-IoT Developer V2.0 (Huawei Certificated IoT Senior Development Engineer) is positioned at constructing the Huawei IoT platform data model, developing the code plug-ins, understanding the Huawei IoT platform Restful API in-depth and applying it to IoTaaS cloud services. The end-cloud application, based on Huawei Lite OS IoT operating system, aims to cultivate application-oriented talents who master the principles of IoT technology and flexibly use Huawei IoT products and technologies for comprehensive innovation. The new version will further increase the proportion of experiments to 60%, and emphasize R&D experiments.

After reading so much knowledge, are you eager to try it out? After the upgrade of Huawei IoT Certificate, it will pay more attention to the experimental link, making the courses more interactive and practical And it will allow you to apply what you have learned and play with IoT technology. Join the Huawei IoT certificate family, the ocean of IoT knowledge is waiting for you.
