Dual-microcontroller based GPRS data transmission control system design

A new method is introduced in GPRS data transmission control system design, which is to employ two microcontrollers as control core. Firstly introduced the GPRS data transmission system, and then gave a new GPRS data transmission control system hardware schematic design and software flow chart design. Compared to systems using single microcontroller, ARM or FPGA control core, the advantage of the new data transmission control system is presented. At last, after three months of testing the control system in real data transmission application, we draw a conclusion that the design is successful.
