传统的电能抄表系统技术落后,其自动化程度远不能满足现有电量管理系统的要求.以ZigBee协议为技术载体,电能计量装置作为应用对象,设计了一种由SOC片上系统级芯片CC2430构成的无线电能集抄系统.CC2430负责ZigBee无线通讯网络的构建,通过其片内的80C51内核控制器采集电能装置的电量数据,并通过网络协调器上传至数据集中器.介绍了系统的体系结构,对抄表系统的终端节点和协调器软件一行了详细设计,并对电能数据的读取过程进行了分析.实践表明,利用ZigBee技术实现的电能抄表系统克服了复杂现场布线带来的难题,具有结构简单、数据传输可靠、快速等特点,大大提高了系统的灵活性.

Design of Power Centralized Meter Reading System Based on ZigBee Technology

The traditional power meter reading system is technically backward,and its automation degree is unable to meet the existing power management systems.Using ZigBee protocol as a technology carrier and power metering device as an application object,a wireless power centralized metering reading system constituted by the system-on-chip CC2430 was designed.ZigBee wireless communication network is constructed by CC2430.CC2430 collects power device metering data through its on-chip 80C51 core controller and the network coordinator upload the data to the concentrator.The system architecture is introduced,and the end-nodes on the meter reading system and software of coordination are designed in detail.In addition,the power data reading process is analyzed.Practice shows that the power meter reading system using ZigBee technology has overcome the complex problems caused by field cabling,and has simple structure,reliable and rapid data transmission,and a series of features,and has greatly improved the flexibility of the system.
