Abstract

The invention provides a communication method and device for transparent transmission of GPRS (General Packet Radio Service) remote data. The device comprises a GPRS module and a power supply module, wherein the GPRS module is used for realizing two-way transparent transmission of data between an external CPU (Central Processing Unit) and a network server; the power supply module is electrically connected with the GPRS module; the GPRS module is electrically connected to the external CPU through a UART (Universal Asynchronous Receiver Transmitter) serial port; an OpenAt system is integrated in the GPRS module; and the OpenAt system is used for calling a WIP (Work In Process) system function to start GPRS network connection, thereby establishing a data link between the GPRS module and the network server. The device is used for realizing the two-way transparent transmission of data, reducing work load of the external CPU and ensuring the stability of GPRS network data transmission.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a communication method and device for GPRS remote data transparent transmission. Background technique [0002] In the field of the Internet of Things, the main thing that needs to be realized is to communicate the data collected by the data terminal (that is, the host) through wired or wireless means, and transmit useful data information to the server system on the Internet through the data transmission device. In the case of short-range communication, radio frequency transmission can be carried out through Bluetooth, infrared rays and open frequency bands, but for long-distance data communication or mobile communication, it needs to be transmitted by means of wireless public network, which uses GPRS network data transmission . However, in existing GPRS data transmission devices, GPRS data transmission is realized by CPU controlling the GPRS communication module to realize GPRS...
