With the development of society, the term “smart home” has become full of our lives, marking the advent of the Internet of Things era. The Internet of Things (IoT, Internet of things), that is, the “Internet where everything is connected”, actually uses information and communication

What is an industrial switch A switch can be understood as an intelligent, high-performance hub. Industrial switches are devices that implement wiring functions in industrial scenarios and can adapt to harsh environments. As data is sent back and forth through the switch, it records the

We are always connected to the internet. We do this with our phones, tablets, laptops, gaming systems, and cars. While some of these use wires and others use proprietary communication methods (albeit wireless), we will focus on Wi-Fi and Wi-Fi security issues. I think this

The growth of the Internet of Things (IoT) has dramatically changed the way consumers interact with their cars, homes, and appliances, but the aptly named second digital revolution is also having a major impact on the industry. From machine learning, machine-to-machine communication to artificial intelligence,

Finished IoT machines should have built-in smart manufacturing capabilities, especially machines with advanced features such as motion control. Even if factories are not currently connected to the Industrial Internet of Things (IIoT), you can be sure that they will be in the future. Fortunately, it’s

Different application scenarios Switch: Mainly used in internal core access, internal data exchange, and more commonly used in LAN; Router: It is a network outlet, mainly responsible for interconnection with operators, and is more commonly used to connect to external networks. For example, there may

One of the protections in industrial routers is often referred to as “anti-surge (EMC)”. There are many reasons for a surge. A surge is a spike pulse with a high rising speed and short duration. Grid overvoltage, switch ignition, reverse source, static electricity, motor/power supply

Among the EIA standard series, the RS485 protocol is considered the most versatile, showing good performance in all four standards of serial communication. This is the reason RS485 is widely used as a communication interface when multiple nodes need to communicate in control or data

The Internet of Things connects things through the network. The currently developed and mature wireless access networks have the characteristics of large capacity and flexibility, can provide faster data transmission rates, and support a wide variety of applications. Currently, GSM modules can be combined with

The LoRaWAN network architecture is deployed in a star topology (as opposed to a mesh topology, such as Zibgee). The base station of a LoRaWAN network laid out in a star topology relays data between sensor nodes and network servers. Communication between sensor nodes and

From the current point of view, Shanghai is the first city in China to fully offline narrowband dial-up Internet access. This may also mean that the already pitiful narrowband dial-up Internet service will become a thing of the past: a year ago, on August 17,

In serial communication, data is sent one bit at a time over a signal line, so in order for the receiving end to receive the data accurately, the sending end must know the sending data for each bit.在RS232中，同步已经定义了
