摘 要: ZigBee技术是新兴的无线双向通信技术,其具备近距离、自组织、低功耗、低复杂度、低速率等特征,在工业控制、智能家居、医疗护理等领域获得了广泛的应用。本系统是基于ZigBee网络的无线遥控器的实现,实现了终端节点与汇聚节点之间控制信息的传输,为构建一个多对一的无线遥控系统提供了底层设施,并且以此底层设施为基础设计了一套窗帘控制系统。系统设计基于模块化的设计思想,将系统分解为终端模块和汇聚模块,在这之下又对模块进行功能分解,分解为若干功能模块。系统硬件基于TI公司的SoC解决方案CC2530,软件协议栈使用的是配套的ZStack,所使用的开发环境是IAR Embedded Workbench for 8051。系统主要实现了ZigBee无线网络的组建,外部控制信息的输入,系统运行状态信息显示以及终端节点和汇聚节点之间的数据传输等功能。54275

Abstract: ZigBee is a wireless technology developed as an open global standard to address the unique needs of short-distance, short-range, low-cost, low-rate, low-power wireless sensor networks. It has been widely used in industrial control, home automation, medical care and other fields. The system is an implementation about wireless remote control based on ZigBee network. In the system, end-device can communicate with coordinator. With this as a basis, you can build a many-to-one wireless remote control system, and then we design a curtain control system. This system is implemented using modularized design method. It is pided into two modules. One is terminal module, and the other is assembly modular. The more generated functional modules are described as well. CC2530 is used as hardware platform, and ZStack is used as ZigBee protocol stack. IAR Embedded Workbench for 8051 is adopted as the development tool. The system has the following functions: ZigBee Networking, receiving external control information, showing working status and data transmission.

1.1 开发背景和意义
无线遥控器被广泛应用于信息收集、工业控制、家电控制、医疗护理等领域中。现行的无线遥控器一般采用红外、蓝牙等技术,遥控器直接与主机通信。由于光的直线传播原理,红外易受障碍物的影响,在障碍物较多,空间要求达不到的情况下,主机的响应率会降低,网络的通畅率会下降,而蓝牙只能建立一对一的通信连接,不能支持多终端的情况,应用场景需要接入多个控制器,那蓝牙也就不能胜任了。
