How to use wireless data terminal?
DTU has been widely used in electricity, environmental protection, LED information publishing, logistics, hydrology, meteorology and other fields. As shown above, although the application of different industries, but the principle of application is the same. Mostly DTU and industry equipment connected, and then set up a wireless communication connection with the background. With the development of Internet of things, DTU is used more and more widely. It helps industry convergence between industries.
As shown on the right, to complete the transmission of data, we need to establish a complete data transmission system. In this system, including: DTU, customer equipment, mobile networks, the background center. At the front end, the DTU and client devices are connected via 232 or 485 interfaces. After the DTU is powered on, register to the mobile GPRS network first, and then go and set up the SOCKET connection with the setting center in the DTU. The backend center serves as the SOCKET server, and DTU is the client for the SOCKET connection. Therefore, only DTU is unable to complete the wireless transmission of data, but also needs the backstage software coordination to use together. After setting up the connection, the front end of the device and the center of the background can wirelessly transmit data over the DTU, and it is bidirectional transmission.
The main function of DTU is to send data from remote devices back to the back office center wirelessly.
The terminal module of wireless data transmission terminal to realize wireless data transmission using, usually connected to PC, wireless data transmission to the mobile phone industry "of the title, because the data transmission time the transmission principle and we usually use the mobile phone in the same. Among them, the typical equipment including wireless data transmission, wireless router, wireless Modem and other equipment, the following describes the most widely used DTU related parameters as a reference.
