Smart gateway, also called industrial IoT smart gateway, wireless data collection gateway, communication collection gateway, wireless gateway, industrial communication gateway, wireless sensor management host, industrial Ethernet serial port smart gateway, RS485 serial port Modbus RTU smart gateway, belongs to wireless sensor Internet product.
The wireless communication module enables all kinds of terminal devices to have the ability to transmit information on the Internet, and is the information portal for all kinds of intelligent terminals to access the Internet of Things. It is the key link that connects the perception layer and the network layer of the Internet of Things. The device data generated by all the terminals of the Interne···
4G RTU integrates traditional industrial RTU and full Netcom/4G/3G/5G data transmission functions into one, realizing comprehensive functions such as collection, counting, control, storage, alarm and transmission. It is also compatible with the data transmission function of the full Netcom/4G/3G/5G IP MODEM.
Narrowband Internet of Things (NB-IoT) technology is widely used in agriculture, industry, government and life. So what is the architecture diagram of Narrowband Internet of Things (NB-IoT) technology? A typical NB-IoT architecture has three layers, which are Perception layer, network layer, application layer.
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.
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).
