Industry 4.0 has come a long way, and the journey to smart manufacturing continues, but what has really made a difference in recent years is the take-off of the Internet of Things (IoT) and the advent of artificial intelligence (AI) solutions.

DTU is the abbreviation of Data Transfer Unit. The Chinese translation is a data transfer module. It is used to transmit the statistical data of the lower-level laser pipe cutting machine such as PLC to the network server on the remote side. It is professionally used to convert the serial port data into IP statistical data or A wireless network intelligent terminal that converts IP data into seria···

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.

At the wireless IoT level, the most fundamentally weak stage is poor, intermittent signal strength.Low signal level leads to poor system characteristics, slow response speed and credibility problems.For installation system staff and other 4G industrial router dealers, how to choose a 4G industrial router network?
