4G industrial wireless terminal, a data transmission terminal equipment mainly based on 4G network, referred to as DTU (Data Transfer unit), is specially used to convert serial port data into IP data or IP data into serial port data, and communicate through wireless Wireless terminal equipment for network transmission. 4G industrial wireless terminals mainly use the 4G network for data transmission. If the local signal is not good, it will automatically switch between the 3G network and the 2G network to ensure the real-time and effectiveness of the data. Most of the 4G industrial wireless terminals on the market are 4G full Netcom. There are 7-mode 14-band, 7-mode 15-band, 7-mode 16-band, etc.

4G industrial wireless terminal applicable scenarios:
(1) Application cases in smart meter reading
Through 4G industrial wireless terminals, power loads can be effectively balanced and power outage accidents reduced. Optimize energy distribution through more accurate big data predictions. Dynamic pricing is enabled by dynamic pricing based on real-time energy demand, either for or to reduce costs. Use accurate real-time data from smart meters to provide useful and detailed feedback on energy consumption. Increase transparency on your monthly energy bills by providing more accurate pricing based on usage. Enable them to adjust their habits based on this information to reduce their monthly electricity usage.
(2) Application cases of smart buildings
For example, construction sites are often unable to use wired broadband services. However, with the development of the Internet of Things, many devices need to be connected to the network to facilitate remote collection of device data and control. 4G DTU can send serial port data to the backend server using the 4G network for observation and control through the transparent transmission cloud. In short, DTU equipment greatly facilitates IoT connections, solves the wiring problems of limited links, and saves costs.
(3) Application cases in sewage treatment
The sewage online monitoring system based on 4G industrial wireless terminals can provide real-time data transmission, remote management and control functions for the sewage discharged by the environmental protection department and enterprises, and realize remote management of sewage monitoring and control. It is an excellent sewage system. Remote automatic monitoring platform solution.
