The combination of mobile communications and practical applications can provide users with flexible and efficient services. In the era of vigorous development of the Internet of Things, the wide application of 4G technology provides a wealth of solutions for all walks of life.
4g data transmission terminal, or 4G DTU , is a terminal module used to realize wireless data transmission. It is usually connected to a lower computer to achieve the purpose of wireless data transmission. Its transmission principle is basically the same as that of the mobile phone data transmission we usually use. It mainly implements 4G Wireless access, transparent data transmission, protocol conversion and other functions.
The main function of the 4G data transmission terminal is to transmit the data of the remote device back to the background center through wireless means. To complete data transmission, a complete data transmission system needs to be established. Included in this system are: DTU , client equipment, mobile network, and backend center. At the front end, DTU is connected to the customer’s equipment through the 232 or 485 interface. After the DTU is powered on and running, it first registers to the mobile 4G network, and then establishes a SOCKET connection with the background center set in the DTU. The backend center serves as the server of SOCKET, and DTU is the client of SOCKET connection. Therefore, DTU alone cannot complete wireless transmission of data, and it also needs to be used with the cooperation of background software. After the connection is established, the front-end device and the back-end center can transmit wireless data through DTU, and it is a two-way transmission.
4g data transmission terminal has the characteristics of reliable performance, flexible networking, convenient configuration, compact and beautiful appearance, etc. It is an ideal choice for building center-to-multipoint, multi-point dispersed, and small and medium-sized wireless data transmission systems. 4g data transmission terminals can form a wireless data transmission system together with the data service center to provide users with an always-on, transparent two-way, fast and flexible virtual private data transmission network, suitable for power automation, industrial monitoring, intelligent transportation, environmental protection, and weather automatic vending. Goods, POS and other industry applications.
