Industrial intelligent gateway is suitable for water, gas and steam pipe network monitoring; EMS (energy management system) signal collection and transmission; municipal water supply and drainage pipe network, pipe trench monitoring; underground pipe gallery environmental monitoring. Signal acquisition and data transmission in the production process of manufacturing and processing enterprises;

DTU is a wireless data transmission terminal, which is the most basic wireless transparent transmission terminal device.The data transfer unit DTU (Data Transfer Unit) is a wireless terminal device specially used to convert serial port data into IP data or convert IP data into serial port data for transmission through a wireless communication network.

The main function of DTU is to transmit data from remote devices back to the back-end center via wired/wireless methods. DTU data transmission methods are different. DTU has full Netcom DTU, GPRS DTU, WIFI DTU, CAN DTU, 4G DTU. Today we will take a look at the structure and work flow of DTU.

After the 4G network card receives the 4G signal, the 4G wireless router converts the signal into a WLAN signal that can be received by the notebook wirelessly. At the same time, it can also be connected to the computer through the LAN port of the 4G router with a network cable, so that it can be realized by using the router function Multi-machine sharing 4G Internet

The rapid development of the Internet of Things puts forward higher requirements for wireless communication technology, and LPWAN, which is designed for low-bandwidth, low-power, long-distance, and massively connected IoT applications, is also rapidly emerging. LPWAN (low-powerWide-AreaNetwork, low-power wide area network), that is, wide area network communication technology. NB-IoT and LoRa have ···

Examples of LoRa applicable scenarios: Smart meter reading: The owner has high requirements for the collection frequency and needs to do data analysis, and has high requirements for network availability;

LoRa is a low-power long-distance wireless communication technology, mainly for applications such as the Internet of Things or M2M, and is an important wireless technology for low-power wide area networks (LPWAN).

RS-485/Modbus is a popular way of network layout, which is characterized by simple and convenient implementation. The RS485 conversion interface is relatively cheap and has a wide variety of types.

The gateway can be a router, a switch or a PC. To communicate within the same network segment, there is no need to intervene the gateway. Only when the host is communicating with a device other than this network segment, it is necessary to send all data packets to the gateway device, and then forward through the gateway device or There are routing processing and so on.

Industrial-grade 4G router has high stability when transmitting and receiving data is one of its main advantages. It uses high-performance industrial-grade wireless modules and industrial-grade high-stability and high-precision components, which can make it resistant to harsh outdoor environments without interruption or loss of data transmission.
