为了解决家庭组网形式单一、布线繁琐、成本较高的问题,提出了一套家居网络节点的远程控制系统,结合ZigBee、GPRS/GSM和Internet通讯各自的优势和特点,设计了基于ARM微处理器sTM32F107VcT6的多种通信技术组合的智能家居网关和基于CC2430无线收发芯片的ZigBee网络控制节点;文中阐述了系统组成结构和运作流程,提出了家居网关和ZigBee节点的硬件组成结构和软件实现方法,实际测试结果表明,该系统组网迅速,通信可靠性会受通信距离和周围环境的影响;在功能上,能够满足家庭远程监控、安防、家电控制的需求,实现了家居网络化和智能化管理,具有较大的实用性和推广价值。
To solve the problems of monotonous form. complicated wiring and high cost of home network, a remote control system for home network nodes was proposed, combining the advantage and features of ZigBee. GPRS/GSM and Internet respectively, a direct--con- nected intelligent home gateway for different communication technologies based on ARM microprocessor STM32F107VCT6 and ZigBee net- work nodes based on wireless transceiver chip CC2430 were designed. This paper proposes the system composition structure and workflow, shows the hardware structure and software process of the gateway and ZigBee nodes. The experimental results show that the system is sta- ble, and able to meet the objective of remote monitoring, home security, home appliances control, family networking and intelligentization, has broad prospects for the application.
