摘要
介绍了一种基于GPRS和远距离ZigBee无线通信技术的网关节点的软硬件设计方法与实现方案。网关采用基于Cortex-M0内核的LPC1227微控制器,结合GSM模块、ZigBee芯片和2.4 GHz无线功率放大芯片,实现了GPRS网络、以太网和无线传感网络的互联。为测试网关功能,搭建了针对路灯节能、监控应用的上位机测试系统。测试表明,网关工作稳定,能够满足低成本、高实时性的要求。
Gateway node hardware and software design and program implementation are given based on GPRS and long-distance ZigBee wireless communication technology. The gateway uses LPC1227 microcontroller based on Cortex-M0 core, combined with GPRS module, ZigBee chips and 2.4G wireless power amplifier chip to implement interconnection between GPRS network, Ethernet and wireless sensor networks. , In order to test the function of wireless gateway, PC test system for energy-saving lights and monitoring application is built. Test results show that the gateway works well, meeting the low-cost, high real-time requirements.
