| Abstract: | GPRS wireless communication is widely used in real life.A method including hardware design and software control based on GPRS wireless communications is proposed in this paper in order to resolve the problem of remote terminal I/O port control.In this scheme,the GPRS module GTM900 hardware connection and software-driven is completed,and the serial communications between GPRS module and LPC2214 processor based on the standard format MODBUS protocol are standardized to achieve the GPRS wireless communications.Experimental results show that the system is low cost,high-speed and high stability. |
