The combination of mobile communications and practical applications can provide users with flexible and efficient services. In the era of booming development of the Internet of Things, the wide application of GPRS technology provides a wealth of solutions for all walks of life.
What GPRS network?
GPRS is the abbreviation of General Packet Radio Service technology. It is also a mobile data service available to GSM mobile phone users. GPRS is a data transmission technology in the second generation of mobile communications.
GPRS has the characteristics of making full use of the existing network, high transmission rate, reasonable tariff, high resource utilization, and always online.
GPRS network coverage is very comprehensive, and wireless data transmission can be supported wherever there is a GPRS signal.
What is a GPRS wireless terminal?
GPRS wireless terminal, also called GPRS DTU , is a wireless terminal device specially used to convert serial data into IP data or convert IP data into serial data and transmit it through the GPRS wireless communication network.
Different from the GPRS module , the GPRS wireless terminal is an external device with a metal shell and supports a variety of interfaces. Users can directly connect sensors and instruments for use.
Take the ZHC2911 of Zongheng Intelligent Control as an example. Its appearance adopts an industrial-grade design and has built-in dual watchdogs. The device can maintain normal operation even under harsh environmental conditions. DTU has rich interfaces and supports RS485/RS232/AI/DI/DO, making it easy to connect to various monitoring equipment. Zongheng Intelligent Control’s GPRS DTU adopts a unique cloud configuration method, supports remote upgrade, supports three working modes of TCP/UDP/HTTP, supports up to 921600 serial port baud rate, two-way continuous sending and receiving, and supports sticky packet splitting, making transmission more efficient! Secondly, the GPRS DTU also supports the active collection and reporting function. There is no need for the user to add a separate controller. By configuring the DTU, the data of external sensors and instruments can be automatically collected at a scheduled time!
Application scenarios of GPRS wireless terminals
GPRS wireless terminals are suitable for use in scenarios where you need to work on the move or when the collection site is in the wild, have certain real-time data requirements, and the amount of data to be transmitted is not particularly large. It can be widely used in agriculture, water conservancy, urban construction, and electric power. Systems, industrial monitoring, traffic management, environmental monitoring, meteorology, coal mines, petroleum, new energy and other industries.
Nowadays, the GPRS network is fully mature and the coverage rate is also very high. Most areas across the country are covered by GPRS signals, and the rates of the GPRS network are relatively cheap. Therefore, using GPRS DTU for data transmission is very cost-effective under appropriate circumstances. choose.
