摘要
GPRS无线通信已经广泛地运用于现实生活中。针对GPRS无线通信远程终端I/O口控制问题,提出了一个从硬件设计到软件控制的整体方案。在该方案中,完成了GPRS模块GTM900的硬件连接设计和软件驱动,规范了GPRS模块与LPC2214处理器之间串口通信的MODBUS协议标准格式,实现了GPRS无线通信。实验结果证明,所提出来的方案成本低,且稳定可靠。
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 .
