The collection and transmission module developed by Zongheng Intelligent Control mainly uses 4G network as the transmission channel, which can realize the mutual transmission of data between serial devices and network servers through the operator’s network. Currently, it can be roughly divided into two categories

The serial port server mainly includes: a power circuit module, an ARM9 processor, a network port circuit module, and a serial port circuit module. The ARM9 processor includes the following interfaces: at least one network port circuit interface and at least one serial port circuit

Different from Internet thinking, fragmentation is the best opportunity for the Internet of Things. By connecting things within a limited range and a short time window, you seize the fleeting opportunity. Most of the companies that practice this principle have achieved good results, and we

RS485 principle This principle, also known as ANSI/TIAEIA-485, TIA-485-A or TIA/EIA-485, is jointly defined by the Electronic Industries Alliance and the Telecommunications Industry Association. Simply put, it is a method used in balanced digital multipoint systems. Standards that define the electrical characteristics of drivers and

Report summary: Wireless transmission is the main information transmission method of the Internet of Things, and the communication module is one of the core components of the Internet of Things. Wireless transmission is mainly divided into three types of connection methods: cellular communication technology, LPWA

As we all know, the PPPoE protocol of industrial routers is a common dial-up Internet access method. So what is its principle? PPPoE: DNS protocol The Internet is essentially just a very large computer network, and in many ways is not unlike a local area
