HTTP and MQTT protocol Features and scope of application REST/HTTP is mainly to simplify the system architecture in the Internet, quickly realize the loose coupling of the interaction between the client and the server, and reduce the interaction delay between the client and the server.

The Internet of Things system consists of four main parts: hardware, software, user interface, and network.The IoT platform connects the four parts into a cohesive, manageable and explainable system.This platform helps to make data ingestion, communication, device management and application operation smooth and unified.

In the first stage, the stand-alone intelligent stage, the stand-alone system needs to accurately sense, recognize, and understand various instructions of the user, such as voice, gestures, etc., and make correct decisions, executions, and feedback. In this process, there is no mutual connection between the equipment and the equipment.

Although AIoT has become the industry's technology development outlet, the development of AIoT will experience three development stages: stand-alone intelligence, interconnected intelligence, and active intelligence.

artificial intelligence (AI) and the Internet of Things (IoT) are considered to be the leading technologies that promote the development of today’s industry. The integration of the two has produced a new concept: AIoT (Intelligent Internet). With the development of 5G technology, AIoT is High hopes are placed in industrial automation.

zoko-link Technology Co., Ltd. is a manufacturer specializing in the development and production of IoT hardware devices. The products apply NB-IOT technology and LORA technology. Let's take a look at the application characteristics and application scenarios of the two technologies.

There are many wireless technologies in the field of IoT applications, such as 2.4GHz WiFi, Bluetooth, Zigbee, etc. These technologies can form a local area network, and these wireless technologies such as 2G/3G/4G can form a wide area network. The advantages and disadvantages are very obvious. It can be summarized as shown in the figure below.

The essence of the Internet of Things is perception and services. The data of the Internet of Things can be traded, which is of great value to big data and cloud computing.The nature of the mobile Internet and the Internet is based on the push and sharing of online information and content on mobile phones and PCs. Information will disappear and be recreated, which has limited value for big data an···

DTU is an abbreviation for Data Terminal Unit. Broadly speaking, when communicating, the module units responsible for sending data information at both ends of the data transmission link are called DTUs. Under its action, format conversion and data collation and verification are performed on the transmitted information.In a narrow sense, DTU generally refers to the lower GPRS/CDMA transmitting term···

According to the communication protocol provided by the PLC communication module or the CPU module, the received data message transmitted by the front-end monitor is analyzed, and then packaged according to commonly used industrial standard protocols, such as OPC and other protocols.
